Chapter One:

    We never would have had that argument if Mom hadnt asked me to give her a ride home. So, really, everything that happened is also her fault. And my Dad was the one who started us on that method of resolving arguments. So it was his fault, too. Of course Faith had her share of the blame. So, although I dont want to downplay my own role in things, they were all partly responsible. Them, and Samuel L. Jackson.

    School was out for summer, at least for me. Exams were still on, but our school board had a policy that if you did well the rest of the year, you could skip the final exams. Both me and my sister, and about a quarter of my friends, did just that. I was looking forward to two months of newfound freedom. For the first summer ever, I had a drivers license, and a car to go with it. It was only a shitty used car, but it was mine.

    The freedom wasnt total I was only sixteen and lived with my parents, and whenever I wanted to go anywhere I either had to beg for gas money or work for it. I had a part time job, but I didnt want to spend the whole summer slaving away and having no fun at all, so I didnt make the job full-time over the summer like most of my friends did.

    The big problem was, with my friends working, either on last minute studying for exams or to save money for college, there wasnt much they could do with me. Freedom gets old when you dont have anybody fun to be free with. My summer of freedom was in danger of becoming a summer of boredom.

    I was wrong. My summer really began on one fine, sunny day when I decided I was going to head out to the mall. I had some idea of checking out some hotties in the food court, as Id done so many times before, and maybe talk to my friend Fred who worked at the Burger King, to see how much work time we could waste without him getting fired. Id spent the previous few days mostly lounging around the house watching movies, so I was excited about doing something different, something that got me out.

    My cell phone rang as I opened the car door. It was my Mom. Whats up?

    She sounded stressed nothing new, there. Listen, Mark, I need you to do me a favor.

    Whatll you pay me?

    She wasnt amused. Tell you what, well take it out of your back rent out of the last sixteen years. I thought I was going to get out of here by now, but theyve just called an emergency budget meeting, and Im going to be late.

    Yeah, yeah, I said, not really caring. What do you want?

    I need you to pick up your sister from her dance lesson. She doesnt have bus fare and your father cant get out of work.

    My plans werent great plans, but they were mine, and now they were out the window. I had to consciously keep from swearing. That would do no good and only get me grounded. Aw, Mom, I was just about to head to the mall.

    You can go after you bring her home.

    I sighed, overly dramatically, told her shed better reimburse me for my gas later, and then ran back into the house to get a pen and paper to jot down the address of the place and the time.

    I was a little late, and Faith was waiting outside by the corner with her bag on her shoulder. Shed already changed out of her dance tights and now wore shorts and a belly shirt.

    My sister Faith was three years younger than me. She was into dance, I never really took an interest in what it involved, just that it was more complicated than ballet, she really enjoyed it, and it sometimes had her practicing around the house in tight little tights. She was a little snobbish about her dancing, acting like it was some great profession that would make her famous one day, which might have been why I deliberately took no interest. I didnt want to encourage the attitude.

    Other than her little hobby, she was a typical kid. I always thought of her as kind of a brat, but I bet most big brothers think that. We were close at some point, but it seemed especially this year when she hit her teens, she closed off. The fun times tapered off, and it seemed the only time we talked was when she was bothering me and asking questions that were stupid or nosy. We got in fights all the time, but that hadnt changed since we were kids.

    She was hot, though. I wasnt proud of thinking that way about my sister, but I never planned on telling anybody, either. While I took after our father and had dark brown hair, she took after Mom and was a redhead (although Mom usually dyed her hair. She also had green eyes, pale skin, and freckles. I teased her often about being a ginger kid, but she wasnt goony looking like a lot of gingers. Her face really looked pretty to me, although Id never admit it. She had a little button nose and even though she hated her freckles, they were cute and didnt explode all over her face like some of our cousins. It was just a nice little patch around the nose. Sometimes they disappeared completely, although since it was summer they were out in force and she hated them. Her body was slim and toned and, I imagined, perfect for dancing. It was a tight little package even though she was a little smaller than most girls her age, small frame and her long limbs contrived to look tall and willowy at the same time.

    I only gave her a brief once over this time, though. I didnt stop to stare because I was angry at being put out of my way. I rolled down the window and pulled to a stop in front of her. Mom wanted me to pick you up.

    She didnt seem at all grateful. It was like she took it for granted that I was going to help her out. Yeah, she told me. Youre late, she said.

    Since I was doing her a favor, I didnt appreciate being talked to like that. So, when she put her hand on the door handle, I said, Hey, not in the front seat. I dont want any of my friends seeing a ginger kid in my car. Besides, you probably smell like a sweaty gym sock. Get in the back.

    She sighed and got in the back without further complaint. We drove a block and then she said, I think I like it better this way. Its like youre my chauffer.

    Dont get used to it.

    Yeah, yeah. She was mercifully silent for a while as she twiddled her thumbs and texted her friends, and I listened to the music on the satellite radio. I was almost able to forget she was there.

    She ruined at illusion while we were stopped at a red light. Ooh, she said. I want to see that movie.

    I glanced around, trying to figure out what she was referring to, when I caught it. There it was, a poster on a bus shelter wall, for one of the upcoming summer blockbusters. Yeah, it might be cool, I agreed. I read the cast list. Huh, I didnt know Samuel L. Jackson was in that. I didnt remember him from the commercials.

    Hes in everything these days, Faith said.

    I gave a little laugh. Yeah. What do you think the odds are that hes bald or has an eye patch in this one?

    I dont think hell have an eye patch. And hes always bald.

    Not always, I said, struggling to think of a recent example where he didnt.

    Faith, instead, began listing all the recent movies where he was bald. Some were not so recent. She ended her little list with, Star Wars. The Matrix.

    He wasnt in the Matrix, I corrected.

    Yes he was, she said, sounding snotty. He was Morpheus.

    No, that was some other guy. I snapped my fingers, trying to remember, but Lawrence Fishburnes name, though on the tip of my tongue, wouldnt come out.

    No, it was Samuel L. Jackson. I just saw it on TV a few weeks ago.

    Youre wrong.

    We went back and forth, arguing Yes he was and No he wasnt several more times, before Faith finally said, Wanna bet?

    Thats where my Dads part of this came in. We got into arguments like this all the time, for our whole lives, over stupid shit. As annoying as the arguments were to us, they were even harder to listen to, and Dad often snapped at us to shut up which only made us continue the argument in whispers, slowly regaining out original volume.

    Finally, one day, years ago, Dad came up with a solution. If youre both so sure, he said, You should bet on it. If we werent convinced enough that we were right that we were willing to bet on it, he explained, we should back down and stop arguing. And once we bet on it, there was no need to argue, you only had to settle the bet.

    It was a pretty good solution for him. Whenever he couldnt take any more of our arguing, hed suggest wed bet on it, and we soon started betting to settle our own fights. Sometimes we bet money, but more often we bet chore duties, services, items. We were scrupulous about keeping the bet, no matter how unfair it seemed to be. Dad made sure of that, too. The one time he caught me welching on a bet, he gave me a spanking Id remember long after Id forgotten what stupid chore I would have had to do. I think it was to attend a tea party with Faith instead of playing baseball with my friends.

    There were two ways the bet system could be used to resolve an argument. Either we agreed on a bet, found out who was right, and the loser paid up their part of it, or one of us bet something so outrageous that the other person backed down because they werent sure they were right. It was like a game of chicken. If the person accepted the ridiculous bet, Dad insisted there still be a chance for the first person to back out, but if you didnt, once you shook on it, you were committed.

    I chose the second way this time. It was too easy. Of course Samuel L. Jackson wasnt in the Matrix. Fine, I said, half-jokingly. If he wasnt in the Matrix, you have to give me a blowjob anytime I want for a week. I dont know what made me think of that. Actually, I do. Sometimes, when a girls annoying you, all you can think of is shoving your cock in her mouth, if only to shut her up. My sister gave me that reaction often.

Chapter Two:

    There was a stunned silence. I thought Id gone too far. I hadnt meant it seriously, only to show her how convinced I was that I was right so shed shut up. Finally, she said, Okay, fine. But if he was the guy in the Matrix, then you have to drive me and my friends around anywhere I want, like a chauffer, for a whole month!

    I shifted about uncomfortably in my seat. I was getting hard. Shed accepted my ridiculous bet. Are you sure you dont want to back out? Do you even know what a blowjob is?

    She rolled her eyes. Of course I know. But it doesnt matter. Im not going to have to do it, because I know Im right. Are you sure YOU dont want to back out? She reached her hand over the back seat, offering the handshake that would seal us in to the terms of the deal.

    For just a moment, I thought of backing down. I had sudden doubts about whether I was wrong and it really WAS Samuel L. Jackson, but I honestly couldnt say if my hesitation came from fear of losing or fear of winning. But the fact was, the potential reward was too good to pass up. At the next red light, I swung around and grabbed her hand. We shook on it.

    We didnt talk much the rest of the ride home. As usual, dads solution stopped the argument, not because wed changed our minds, but because it now was just a matter of finding out. I watched Faith in the rear view mirror, and thought I could see some anxiety there, so maybe she was worried. I wasnt.

    I practically raced to the computer in the family room, and my sister followed at a slower pace. By the time she reached me, I had already called up Wikipedia. It was there, in black and white (and blue, for links). Samuel L. Jackson was not in the Matrix. Lawrence Fishburne was.

    Faiths face was frozen in shock. Anybody can edit Wikipedia, she said. Maybe somebody just got it wrong. So, I pulled up the Internet Movie Database. It agreed. No, she said breathlessly. I was sure.

    They look a lot alike, I said, a wolfish grin on my face.

    Youre not going to actually make me do that, are you?

    What? You want to welch out? You know thats against the rules.

    Yeah, but you said anytime you want. Come on, Mark you dont really want one from me, do you?

    It was a technicality. I could have let her get away, and say that although she still had to give me a blowjob anytime I want for the next week, Id just let the time expire without asking for it. I could have traded a promise to do that for some other chore. I should have done that. But Id never had a blowjob before. I had a hand job from a girl at a party, but that wasnt the same thing.

    Sorry, I told her. A bets a bet.

    But its not fair, she said. Giving you a blowjob anytime you want means I could be doing it all day!

    I rolled my eyes. Please, what do you think, guys masturbate nonstop? It would only be two or three a day, probably.

    She said, Oh, and looked thoughtful for a moment, before giving out one of her sighs. Her sighs were like amateur drama productions, full of exasperation, and conveying in no uncertain terms that she thought she was above whatever shes been forced into doing. Okay fine, she said, adding ice to the last word. I suppose youll want one now.

    As a matter of fact. My dick was starting to strain against my pants, so I stepped back from the computer, unzipped and whipped out my cock. She looked at it, got down on her knees, and, on those knees shuffled towards me to close the distance. My cock was pointed right at her face, a little precum already at the tip.

    Her mouth opened into a wide oval as though testing the proper width she would use, then closed her eyes and extended her tongue as she leaned forward. As soon as her tongue touched it she drew back as though stung, and made a face. Gross.

    Sooner you do it, the sooner youll get it over with.

    She moved forward again, and this time took me in her mouth, and closing over me. She only went halfway down, and her tongue didnt move very much, she just moved her head back and forth on it. It still felt incredible. Every few seconds, she pulled off entirely to take a breath and looked up at me with a glare, but she didnt need to be told to go right back to it. It was just delicious seeing her mane of red hair bobbing up and down on my dick. After her third air-break, she started applying some light suction, and the pleasure doubled while I watched her cheeks go concave.

    My dick began to pulse with the familiar sensation, and I groaned lightly, giving her the only warning I planned on that something was coming. I started cumming when she was on an upstroke, getting one glob of my cum in her mouth right away. She pulled off, surprised, and the next big glob landed on her face, on one side of her nose, running down along the freckled highway towards her cheek. The next landed on the other side of her face, her cheek, as she turned away with a shriek, and tried to get up. I got one shot on her shirt and most of the remainder dribbled out on the floor.

    Ewww! she cried. You didnt have to shoot on my face!

    Where else was I going to shoot? I asked. If you didnt want it in the face, you should have swallowed it all.

    That is so gross, she said. Ive got to go take a shower.

    Dont blame me, I said. Blame Samuel L. Jackson. She headed off towards the nearest bathroom, and after that locked herself in her room. I cleaned up what cum was on the floor before one of my parents freaked. Id make sure the rest of that weeks blowjobs would be in a less public place than the family room.

    I had a huge shit-eating grin that whole day. That evening, while our parents were downstairs, I caught Faiths eye and pointed to my penis, and then to my room, with a grin on my face. She sighed, but followed me. Id laid a towel on the floor and sat down on my bed, then pulled down my pants. Can you at least warn me before you shoot this time? she asked.

    Yeah, okay.

    She went down with less hesitation this time, just going down on me like shed done it all her life. Now that she had the rhythm down and didnt have to come up for breathe, it was more pleasurable, but I didnt want to cum so fast this time. I wanted to savor it, and I wanted her to work at it. You know you could use your tongue more, I said. She complied instantly, and I could feel it moving from the underside of my head to the side, and over.

    I looked down at her and noticed she had her eyes open, watching my face. I smiled down at her and gently stroked the side of her flushed cheek with a knuckle a few times. I thought she tilted her face into the stroke, but it was probably my imagination. Soon after, she pulled back to just suck on the tip and teased it with her tongue, then went down even farther than she had before. That was enough to tip me over the edge, into the point of no return. Okay, Faith. Im about to blow my load.

    She pulled off quickly, and then rolled out of the way, leaving me to spurt out into empty air. Most of it landed on the towel, though some got on my floor. Wow, you dont have to be such a bitch about it.

    Hey I just didnt want you to get your goo all over me again.

    I told you the best way to do that was just to swallow it all. Its not really a blowjob if you dont swallow. Besides, I added, its supposed to be good for the complexion. Maybe itll clear up those freckles.

    Really? she said, and leaned back over the goo-covered towel to have a look at it. My dick was still semi-hard, and I couldnt resist the opportunity, I wiped my slimy dick on her cheek. There was still plenty of my sperm on it, and I thought it was pretty funny to see my sister with my jism on her face. She didnt. You jerk! she yelled, and stormed out of my room in a huff to wash up.

    I slept pretty well that night, I can tell you, and was looking forward to the many blowjobs to come.

Chapter Three:

    The next morning, I waited until both our parents were out to work, then went to knock on Faiths door. She didnt answer. After one more try, I just opened it, but she wasnt there. She wasnt anywhere else in the house, either.

    Annoyed, and with a morning hard-on, I phoned her. What do you want, Mark? she said. She must have known it was me from the display.

    Where are you?

    Im at Sallys house. Were going to listen to music.

    Im sure that sounds like fun, I said, but Ive got a boner and want a blow job.

    What? Thats not fair.

    Sure it is. The bet was that youd give me a blowjob every time I want one. Not every time I want one and you happen to be home.

    So Im supposed to be ready every time you she didnt finish the sentence. I could hear others in the background talking faintly, so she was probably worried she would be overheard.

    That was the bet you agreed to. Dont blame me, blame Samuel L. Jackson.

    The other line was silent for a long time. I cant believe youre making me do this.

    Quicker you get over here, the quicker youll be done. Ill be waiting for you in your room. I hung up. I was being a jerk, but I really liked the idea of having her at my beck and call. This deal wouldnt last forever, so I thought Id better exploit it while I could.

    She came up to her room about five minutes later. Sally only lived just up the block and across the street. She shook her head at me and said, Come on, whip it out, I want to go back.

    I dont know, I said. I might not be in the mood anymore. But I might be in the mood in an hour

    She sprinted over to me and pushed me back, but she had a playful expression on her face. Youre lucky Im doing this at all. I should go tell Mom and Dad on you. But from her look, I had no worries she actually would. That never happened anymore. By an unspoken agreement, we handled our problems ourselves.

    I gave up the pretense of disinterest, though, since I really did want the blowjob, and pulled out my cock. She really seemed to want to rush this job, but that had the effect of making everything she did filled with more enthusiasm, although she slowed down halfway through to pull out her phone when it began vibrating. She stopped moving her head to read from the display and, without taking her lips off my cock, typed out a text message reply. I would have loved to have read that one. cnt tlk now, sucking bros cock. When she finished replying, she went back to a more intensive sucking. I tried to hold out as long as I could, but pretty soon I had to tell her I was ready.

    She didnt pull off this time, just kept sucking until I finished cumming. Id miss seeing my sperm all over her face, but imagine it running down her tongue and down into her belly was a great substitute. Wow, Squirt, I said when I was down to dribbles. Youre getting better at this. You actually swallowed this time.

    She pulled her mouth off and wiped the corner of her lip wih the side of her hand. Shut up. I just didnt want to get it all over my room. Or to have to take a shower. She stood up, dusted off her knees. Now I just need mouthwash.

    What, you dont want to go back to your friends with cock breath?

    She smiled a little. Not really. She put her hand up to her mouth and breathed in, then smelled it. After making a face, she said, Youre not going to be calling me back here throughout the day, are you?

    I dont know I said, letting an exaggerated amount of uncertainty into my voice, then I cracked a smile. Tell you what, since you did such a good job this time and swallowed like a good girl, Ill wait until you come back on your own.

    Thanks, she said, and went into the bathroom.

    When she was finished gargling, I met her again in the hallway. Hey, was it true what you said about swallowing cum being good for the skin?

    I shrugged. Wikipedia says it is. Wikipedia said no such thing. But if she called me on it, I could just say somebody must have changed it.

    Whether she believed it or not, she swallowed my cum that night too, without any complaint. I made it last a long time, too, mostly just lying back in my bed and staring at the ceiling as she sat beside me, slurping down my meat. I figured Id pay her back for the text message stunt and phoned my buddy Fred. It distracted me a little and made me last longer, and I got a big kick out of it, but I cut the call short because I didnt want to cum on the phone to a friend. Its just rude.

    I could get used to this, I thought as she sucked on my shooting prick. I was going to have to make blowjobs appear as a regular part of wagers if she wanted to get into stupid arguments with me. Maybe I could even get more than that. Id have to find the balance between what she might do if she was confident, and what would just make her back down no matter what, but now that the precedent had been set, it was only a matter of experimentation. She left and, as she almost always did, retreated first to the bathroom and then to her room, where she played music.

    The next morning, she was in her room, so I pointed to my cock and she got right down to it. She was getting better at it each time, and though last time Id complimented her, I wanted to try something else, see if I could get her to try harder to please me. I dont know, I said. Im just not feeling it.

    She picked up speed and began to use her tongue more, so I had to think about this squirrel I hit with my car a few weeks ago to keep me from going off. You know what might make this go faster? If you took your clothes off. Gave me something to look at.

    Faith pulled her mouth off my dick to look at me. Mark, youre not supposed to see me naked. Im your sister.

    When youre giving me head, youre not my sister, I said, youre just a good place to bust my nut. I might as well see some pussy while Im doing it.

    Shut up, youre such a freak, she said, but took my cock back into her mouth and resumed sliding her tongue underneath it.

    It was worth a try. I really wanted to see what she looked like naked. She didnt have much of a body, but I didnt need one to make me happy. Despite my best efforts to hold off, pretty soon I was blowing another freshly brewed batch of ball-juice into her belly. Nice job, I said. Want to make me some breakfast? She gave a disgusted snort in reply and left.

    I dont want to give you the impression that Im a total jerk, or that me and my sister hated each other. I am a bit of a jerk, but Faith and I have always been a little antagonistic. Its just our way, since we were kids. We insulted each other and made fun of each other, but we both knew there was love underneath that. Why, because of the blowjobs, I was even nicer to her than I usually was. I willingly gave her and her friends rides in my car a few times, like I would have had to do if I won the bet. I wouldnt have done that before, waste my gas money like that, but I figured it was the least I could do. A good blowjob is worth a little gas money.

    Maybe I was a total asshole for putting her through that at all, forcing her to regularly suck her own brothers dick... but I didnt beat myself up over it, because I had a theory. After almost every blowjob, if she didnt have somewhere to be, shed lock herself in her room and put the music on. At first I thought she was just angry with me, but when I put the music on and locked my door, a lot of times it just was because I wanted to masturbate. I didnt want anybody to hear the rhythmic sound of my chair or bed shuffling in time to my hand movements, or a little groan that might escape my lips, and the music covered that.

    I had a vivid image in my head, that after sucking me off, she ran to her room, and rubbed her little pussy. I hadnt seen it, at least not as far as I could remember, but I could imagine her rubbing a pink little clit on a hairless mound, remembering what shed just done. She always seemed in a better mood after she finally came out. So that became what I told myself, to push past any bad feelings, that she secretly enjoyed it as much as I did. I convinced myself that my sister was as much of a freak as I was.

Chapter Four:

    Theres no need to give a blow-by-blowjob account. Faith kept on sucking me off whenever I requested, and she usually swallowed, but always refused when I asked to see her tits or anything else. With the days specified in the wager running down, I had, at last, a brilliant idea. I couldnt pull it off while Mom and Dad were there, but the last morning of my privileges, after theyd left for work, I knocked on the door to Faiths room.

    Im going to take a shower, I said. We typically warned each other of this fact, because turning on the water in the kitchen would drastically change the temperature of the water in the shower.

    Yeah, you need one, she said, the barb automatic and unthinking, and therefore didnt really hurt. She didnt even look up from the computer. I dont need it.

    I waited in her doorframe. Yeah, but, heres the thing I kind of want a blowjob in the shower.

    She finally looked up. Cant it wait until after? Or I could give it to you now

    Whenever I want, I reminded her. And I want it in the shower. So you better get undressed.

    She sighed, and made sure I heard it, then muttered, Damn you, Samuel L. Jackson. She made sure I heard that too. Ill be in there in a minute, she said.

    I decided to leave her to getting herself ready, and went into the bathroom, leaving the door open. I started the water so it would warm up to a nice temperature, and then stripped down. My cock sprang, fully hard, out of my boxers.

    I got in the water and called out, Im waiting, loud enough for her to hear me in her room. She came storming in, with a pout on her face.

    She wasnt naked. But it was a step in the right direction.

    Faith was wearing only the bottom piece of a green two-piece swimsuit. That left her topless. I stared at her. She had a lithe dancers body, without much fat on her at all, and barely any tits at all. In fact, if you looked at her from wrong way, you might think she was completely flat. It was only at certain angles that her breasts revealed themselves, like they were hiding the rest of the time.

    The boobs may not have been great, but her nipples were glorious, poking visibly out, surrounded by a well-defined circle of pink. I licked my lips involuntarily at the sight of them. Shut up, she said, feeling my gaze. I couldnt find the fucking top half, she explained. With one arm, she tried to cover herself, but it was too late, Id already seen what she had to see.

    Im not complaining, I said.

    I bet. She pulled back the shower curtain with her other hand and stepped over the edge of the bathtub, then kneeled in the water pooling by my feet. I bopped her in the face with my cock. It bounced off her lip, then she caught it in her hand on the rebound and placed it inside where it belonged.

    I wished I had eyes in my knees so I could stare at those nipples, but her back blocked my view, so had to be content with looking her head bobbing up and down and the little bit of ass crack I could see poking out of her suit. You know, theres something wrong with people who wear bathing suits in the shower, I said, but she wouldnt take the hint and remove it.

    She licked and sucked on my dick for several minutes, but this time, when I told her I was ready, she pulled off. Instead of squirting down her throat, I hit her face with one glob, then I angled down where I hit mostly her shoulder and neck before I managed to get just a little bit on her tits.

    Whats wrong? I asked. Didnt want to swallow?

    I never do, she said. I only do it so I dont have to clean up. Next time dont ask me to get in the shower with you if you want me to swallow. Maybe she thought she was teaching me a lesson, but she wasnt. It was almost as hot to watch her take my load on her face as it was to know she was swallowing it.

    I got a little bonus treat that time, too. She stood up and pushed past me to get into the shower spray, to wash my semen off her body and down the drain. As she did, her chest brushed against my arm. I also got a nice look as the stream of water ran down her chest, doing a little jump off her perky nipple.

    Once her face was clean, she stepped out and grabbed my towel to dry off. Enjoy the rest of your shower. I dont need one. She dried herself quickly, then wrapped my towel and left, taking it with her. Her door slammed seconds later, and music started up again. I soaped myself up and cleaned myself off while imagining her fingers thrusting in her pussy.

    I later had to sprint out naked to get another towel, but I didnt mind, no one else was home. By the time I was done, dressed and my hair all styled, Faith was downstairs, so I tiptoed into her room and looked around. There were clothes strewn all over, and I smiled in satisfaction as I realized that she had evidently passed up a blue one-piece swimsuit in favor of the green bottoms she took to the shower. She had an alternative to showing me her tits, and she didnt take it. It was all new evidence for my theory that she wanted it.

    Unfortunately, I was running out of time to exploit the deal. It was the last day I would be entitled to blowjobs, and I certainly couldnt try the shower trick again. I had some plans with friends who were finished their exams that day, and I couldnt do it when our parents might come home and wonder why we were both in the shower together. It wasnt a big risk to get a blowjob in one of our rooms while they were home, because our parents tromped around the house loudly and you could hear them coming while they were halfway down the hall. In the shower, it would be a lot harder to get into an innocent looking position.

    I met Faith in the kitchen, and we talked a bit before I went to see my friends. To be prepared, and to be nice, I asked her if she was going to need a ride home from Dance class that day, but she told me it was cancelled this week, so she was just going to hang around the house and watch videos. When I learned that, I seriously considered cancelling my plans with my friends to get whatever blowjobs I could. I decided not to, because I had little time to see my buddies lately, and you know what they say, Bros before hos.

    That was a mistake. The rules bullshit. None of my bros would give me blowjobs. Not that I wanted any from them, Im just saying I was an idiot to give up blowjob time to hang out with them. It was fun hanging out with them, but nothing compared to getting my cock sucked by my sister.

    I got one last session of head from her in her room that night. By established history and a lot of prior arguments, bets of one week or one day or one month or whatever were always rounded up to the next day, so even though we started in the middle of the day last week, I could press her for one until we went to bed. So I did.

    It was only after I left her room that I realized she never mentioned it was the last. Neither had I.

    So I decided to press my luck. The next morning, after the folks were gone, I went into her room one more time, mentally crossing my fingers. Hey, I said. Want to give me a blowjob?

    She sighed, and went down on me again. It was excellent, and she swallowed my load, and was all the more enjoyable because it was a freebie. Thanks, I said after I was done.

    Dont thank me, she muttered after a last swallow. I dont want to be doing this. Thank Samuel L. Jackson.

    It was idiotic of me, but I couldnt resist rubbing in her face. Both literally and figuratively. As I wiped my dick on her face, I said, Sammy had nothing to do with this one. The bet was only for one week, remember?

    Her mouth opened wide, and then her face turned red. You jerk, she yelled. She grabbed a pillow from her bed nearby and threw it at my head, but barely missed me. I was thrown off because my dance class was cancelled. Why didnt you tell me?

    I never said you had to do it, I just asked you if you wanted to. You seemed to enjoy it so much the other times.

    Fuck you, she said.

    If you wanted, but youd have to give me a few minutes to recharge.

    Shut up and get out of my room. You asshole. The only reason Id go anywhere near your smelly cock was because of the bet.

    She pushed me towards the door until I was out of the room, and then slammed it in my face. I heard the lock click, and then a sound I thought was her flumping on her bed. I stayed there being super quiet. She hadnt turned music on, and it was extremely quiet in there. After a few minutes, I thought I heard a repeated whimpering sound. Not like she was crying Id heard her cry before and this wasnt it. This had a little bit of a grunt in it. I imagined herself shoving something into her pussy that was a little bigger than comfortable, and the sound fit with what noises Id imagine shed make. I grinned. She was more into it than even I expected.

    When she left that day, I went back in there, looking for anything she might have shoved inside her and gave it a sniff. Hair brushes, sharpies, thin cans of styling goo. To my disappointment, I found no candidates with an unusual scent. Either she hid it, used only her fingers, or I was wrong entirely.

    I didnt think I was wrong. But for a while, she made me doubt myself.

Chapter Five:

    Over the next few days, I asked Faith several times if she wanted to give me a blowjob. She refused each time, acting disgusted that Id asked. I also regularly suggested she walk around topless. Ive already seen your little tater tots. She just told me to shut up.

    I didnt get it. I was sure she wanted it. But whether I asked nicely or crudely, I was always rebuffed, sometimes with an insult, more often with just cold silence. Maybe she was just on the rag.

    Whatever the reasoning, I started to think I was wrong, Id inflated the whole situation in my head, that this was just a one-time freak occurrence. It wasnt until we had our next argument, a few days after the July 4th holiday, that I thought anything might happen again.

    It was about a half hour after I had lunch, and I was starting to get the munchies. Im not a big guy but I can put away a lot of food, especially when Im bored, and when Im watching a movie I need something to chow down on. I looked through every one of the cupboards, but we were out of the usual staples snacks, chips, popcorn, crackers. So I went to the fridge, where I found, in the freezer, a large frozen pizza, Three Meat Special. By the time it cooked, I would be even hungrier than I was, so I decided I could probably eat it all, and started preheating the oven.

    Faith walked down from her room as I was cutting the pizza on the counter, after it had cooked and cooled some. I was in a good mood, so I nodded towards her. Do you want some pizza? Its got sausage on it. I know how you like the sausage

    She ignored my innuendo but actually seemed to considered the pizza for a moment, before she shook her head. Maybe later. I didnt really expect her to have any. Like a lot of girls, she was way too concerned about watching her weight. I guess I couldnt complain about that, whatever she was doing was working for her.

    Wont be a later, I warned her as I plucked off a piece of pepperoni and put it in my mouth. Thisll be gone in ten minutes. I wasnt actually serious. I planned on stretching it out over the course of the whole movie, although I knew I could eat it that fast if pressed. I wasnt just a big eater, I was a fast one too. It was a wonder I wasnt huge. If Faith shared enough of genes, she might not have needed to watch her weight at all.

    Faith looked at the pizza, then made a sort of cluck of disapproval by striking the roof of her mouth with her tongue. Youre such a pig, Mark. And didnt you just eat lunch? she asked. Theres no way youll eat that whole thing in ten minutes.

    That was a challenge. At that point, even though I had been exaggerating, I felt compelled to defend my honor. Theres two things girls should not doubt about men, their sexual stamina, or their ability to eat. Both will inspire boasts and offers to prove them wrong. This? I could eat this in ten minutes easily!

    No way, she said. Maybe if you were starving, but

    I interrupted her. I AM starving. I ate, like, a whole hour ago.

    You just think youre hungry. Once you start eating, youll feel full again and you wont be able to eat more than a slice or two.

    I think I know my own body. Ive got more than enough room.

    Wanna bet? she said.

    My ears pricked up. What? That I can eat this whole thing? Thats a sucker bet.

    No, that you can eat it all in ten minutes.

    That would be a little harder, but I knew I could be up to it. Fine, I said after a moments thought. What do you want to bet?

    She hesitated, seemed to take a few seconds to think while she Ummmed , and then, while I was getting some cola from the fridge, finally suggested, If I win, you have to be my chauffer for a month.

    I slammed the fridge door and looked back at her, surprised. In our last wager, wed already established that a week of blowjobs was a fair wager against one month. To propose the same thing was practically daring me to make the same type of bet.

    My previous doubts were gone, my theory back in full force. I decided that she must want it after all. She was only looking for an excuse. She sounded so sure of herself, but she must have known she was going to lose. I dont think Ive ever eaten a pizza that fast before, but Ive fast-eaten other things.

    And since she was practically daring me to make the bet another round of blowjobs, I wondered how much I could push it. Okay, I said. But if I win, you have to let me watch every time you masturbate. For a month.

    She wrinkled her nose and rolled her eyes. Youre a fucking perv-o. What makes you think I even masturbate?

    I was pretty sure of myself at this point, but the question did bring up something I hadnt considered. She could get out of it by refusing to masturbate. Girls were supposed to be able to do go without longer than boys. If she needed an excuse, Id better give her a good one. Then youll have to try, at least I pulled a number out of my hat. Ten times. And you have to have ten orgasms, or we go on to the same deal next month. If I won, it would guarantee me something to see, and I was sure that once I got her masturbating in front of me, I could push her into more. I held my breath, waiting for her to decide.

    Fine, she said. Youre losing this time anyway. I saw what you had for lunch. Theres no way you can eat that in ten minutes. We shook on it.

    I dont think I need to tell you who won the bet. It wasnt quite as easy as I thought. Not because I was too full to pack it all in there, but because she insisted that the ten minutes started right away, and the pizza was still pretty hot. But by rolling the crust up the first few to protect my tongue from hot cheese and sauce, and having a lot of cola on hand, I was able to get through them, and by the time I got to the fourth slice, about five minutes in, they were cool enough to eat normally.

    The last one was tough. You reach a point, especially when youve been drinking a lot of carbonated beverages, where it gets hard to eat fast, and you feel bloated. Its usually an illusion you just have to burp. But time was running out. I pushed repeatedly on my stomach, forced the air out, and finished the last piece, swallowing the crust with about twenty seconds to spare.

    Faith acted surprised and disappointed, but I really think it was an act. How could she not expect that Id win? She just said, Oh, my, God, with a full seconds pause between words. I cant believe you were able to do that. Youre a freak.

    After I wiped the smirk off my face, I said, A freak who just won a bet.

    She repeated, I cant believe it. Why did I ever agree to such a retarded bet? She made a shuddering sound, and left.

    I let her go. I needed time to let the meal settle. After about a half an hour (and a visit to the bathroom), I went to find her in her room. I didnt knock privacy seemed to be unimportant if I was going to be seeing what I was going to be seeing. As I ducked my head in the door, I asked, So, I dont want to put you off your usual schedule or anything but I need to plan my day. What time do you usually masturbate?

    In bed, or in the shower, she told me, quietly.

    I gave a self-satisfied smile. I knew you did it.

    Faith let out a snort of exasperation. I dont want you being creepy and watching me when Im about to sleep. Itd give me nightmares. Id better do it now.


****
Chapter Six:

    She told me she had to set the mood first, or she wouldnt be able to do it at all, especially with me watching. For the next several minutes, Faith rearranged her room, picking discarded clothes off the bed, and arranging some pillows in a comfortable way. I watched from the door, enjoying her ass bounce up and down beneath her tight shorts as bent over or moved across the room to do one more thing, like light candles or put on some music. I had the feeling she was stalling, but she couldnt stall forever, so I just waited, already semi-hard, knowing what was coming.

    When she was ready, room dim, music on, the smell of vanilla wafting in from her scented candles, Faith peeled off her shorts. Underneath she had plain white cotton panties with a little flower design on the front. I cant believe Im doing this. I looked for, and found, a spot of wetness at the bottom to confirm my suspicion that she was putting on an act of reluctance.

    I sure can. She sat on the bed, hooked her thumbs under the waistband of her panties, then lifted her ass slightly and pulled them off. I knelt beside her bed to get a good look. Thats a cute pussy, I said. I wasnt just being polite, either. It was almost closed, with most of it all tucked inside, but with a little streak of pink, glistening with moisture, visible in the middle of the slit, and the little hood poking out at the top. It was crowned with a small tangle of red hair. That was the biggest difference compared to my imagination, I never pictured any hair at all. I guess my little sister was more grown up than Id thought.

    Shut up and lets just get this over with, she said, and ran her finger up and down her slit. I kept my mouth shut and just watched for a while. She started rubbing around her slit up and down, but then soon started shoving two fingers inside her and pumping them in an out. I changed position, to kneel directly in front of her, staring into the hole as her fingers withdrew, then returned, again and again. Whenever she paused for a moment to rub her clit, the hole closed up almost right away, giving me no time to glimpse at the inside. I imagined how tight it must have been.

    Do you ever use anything other than your fingers? I asked.

    She made a soft noise, like an Mmph, and it took a second for her to answer in words. I used a hairbrush once, but it really hurt.

    You might have broken your hymen, I said. Spread it out and Ill have a look. I didnt think she actually would, but she stopped and used both hands to spread open the outer lips of her pussy. I looked all the way inside her tight little hole, and didnt see anything that looked like a hymen, although Id never seen one in person before. Yeah, I decided. Looks like you lost your virginity to your hairbrush, I teased. Way to go.

    Her comeback was pretty lame. Better than losing it to your hand. Guys didnt lose their virginity to their hand. Even by the most liberal definition, you needed the warm, wet, hole of another person. She went back to rubbing her clit, the wetness shed gathered from her slit dripping all over. The bottom bits of her pubic hair were now damp and matted.

    I watched for about five minutes, then I couldnt take anymore, my dick was threatening explode inside my shorts, so I pulled it out and started rubbing up and down.

    Oh, gross, Faith said, but she accelerated finger-fucking herself, and for a short time we were almost in synch, her self-penetrations happening in time to my down strokes. Suddenly, she pulled her wet fingers out and turned on her back, giving me a nice look at her little ass cheeks, and reached across to her night table to grab a Kleenex and some lotion.

    Thats it, she said. Im out. She began to wipe her hands off, and rubbed them down with some lotion. Then she pulled up her panties and took a few prancing steps to pick up her shorts.

    Didnt look like you had a chance to cum to me, I said.

    She turned on the lights. I didnt, but Im not doing it with you masturbating. If you want to whack off, go to your own room.

    I went to my own room, but didnt finish myself off. The sudden cold reception threw me off a little. It didnt make sense. I was sure shed be into it. Disappointed, I watched some of that movie I had been planning earlier, and in about an hour, she knocked on my door and said, Okay, I want to try it again.

    We didnt go back to her room where everything was prepared. She just sat beside me and stripped down, placed her palm on her pussy, and began rubbing, inserting different fingers in. She gradually leaned back further and further until she was lying down, legs hanging over the edge of the bed. I watched quietly as she got to a point of regular heavy exhalations mixed in with small whimpers.

    I decided to take a risk. I was seated, so I lay one of my hands on her shoulder, the one that was closest to me and not working on her pussy. Then, I slid under her tank top, making progress on her breasts. My finger found her nipple and rolled it under my finger for nearly a minute before she said, Stop that, and pulled away, just enough for me to get the message and remove my hand. But before she did, her tongue ran out over her lips, moistening it, and it seemed to me she was getting more into playing with her clit.

    She went back to focusing on her pussy, and she reached a point where, when her eyes were open at all, they had a glassy, far away stare. I made another move and slid my hand down her belly and over her mouth. The little bit of pubic hair didnt stop me at all, and nor did anything else. While her fingers were inside her hole, I took over on her clit, rubbing back and forth slightly.

    She moaned in surprise and pleasure and though she said stop, her voice had a higher pitch to it and no anger, just a sense of urgency. I kept rubbing, pretending not to hear. Her hand closed on top of mine. At first I thought it was to push it away, but instead she started moving it up down and around in an erratic pattern. I realized her legs were shaking. She let out a sharp, severe, shuddering breath with a wordless cry following close behind.

    After she recovered, she elbowed me and moved to get dressed. Mark! I never said you could touch me.

    It just seemed like you needed help getting over the hump, I said. You should be thanking me. You only have nine more to go. I looked at my fingers, still a little damp with her wetness, and licked them. Mmmm, I said. Finger lickin good. I couldnt say exactly what it tasted like, especially since my taste buds were still a little raw from hot pizza. The best I can describe is, it tasted like lightheaded feels.

    Youre so gross. I cant believe youre making me do this.

    Come see me when you want your next orgasm. She stormed out and slammed the door to make her point. I jacked off while smelling her scent on my fingers.

Chapter Seven:

    It was two days before Faith came for me again. I had to work both days, so I dont know if she would have come otherwise, but the first morning I was free, she found me and told me, Im going to touch myself again. But you have to promise.

    I acted innocent. Promise what?

    No touching me.

    You seemed like you enjoyed it last time.

    I didnt. It was nasty, she said softly.

    In certain tones of voice, nasty sounds more like a compliment than a complaint. This one was too close to call. I remembered vividly the feel of her hand, directing mine. So nasty that you came. Right.

    Do you want to watch, or not? Because if you dont, Im counting it as one anyway.

    That power play wasnt supported by the rules of the bet, but I followed her to her room anyway. She had the mood set already, and so without any ceremony, she just laid down and stripped, this time getting all the way nude. She also had a chair set up, a few feet away, close enough that I could get a good look but far enough that I couldnt easily reach. I took the invitation. Perhaps to prevent me from becoming too inspired to want to touch her breasts or pussy again, she laid on her stomach and grinded against her hand from above, leaving little space for me to slip a hand in. Her head was turned towards me, staring. I focused on watching her ass bobbing in the air, and the hand buried underneath.

    After watching her do herself for some time, I had to touch something. I pulled my dick out and began to stroke it again. I told you, she said. If youre going to jack off, Im stopping. Thats not part of the bet.

    You dont seem to understand, I said. Watching you like this is incredibly hot. Ive got a boner and Ive got to take care of it one way or another. If you stop every time I jack off, then youll be stopping every time. And if you dont get your cums in this month, we start over again next month.

    She was resigned to her defeat. Okay. But no touching me.

    I agreed, and stroked myself slowly as she rubbed her pussy from below and sometimes outright humped her hand. She never kept her eyes off me, and most of the time it wasnt on my face, but on my cock.

    When it was getting close, I stoop up, walked right up to her bed, pointing my dick at her mouth. Mark! I said no touching.

    Im not touching you, I said, and continued to pump my hand up and down on my dick. Im about to cum, but Im not touching you. I had a flashback to times when we were very young and I would torment her by doing everything short of touching her, so she couldnt tell on me.

    But youre going to spooge on me!

    But Im still not touching you, I said. If I cum, I cum. If you dont want to get messy, you could always put it in your mouth. I dont mind if YOU touch ME. She stared at my throbbing cock without speaking. I stopped for a moment to let her have a good look. Come on, dont act like youve never done it before. I started up again. Another few seconds, another few strokes, passed as she just glared at me. Getting pretty close, I warned.

    She closed her eyes and opened her mouth and, taking that as an invitation, I closed the distance and put it in. Her mouth closed over, creating a tight seal and I swung my hips in and out, fucking her mouth while I still could before I came. I had my eyes on her hands, and she never broke stride with her masturbating either. If anything she was moving faster. I came and my sister drank what I gave her, down to the last drop.

    I now was almost certain what I was doing turned her on, even though she wouldnt admit it. It was nearly hilarious, the way she kept denying it, acting like she was being all abused, all while putting herself in the position in the first place and getting hot while it happened.

    She came that morning, too, a few minutes later. Id actually hoped she wouldnt, because it risked her finishing her required part of the deal too fast. If she didnt cum in front of me ten times, Id get another month to play with her. If she did, she might stop masturbating, if only because she couldnt tell herself she was forced to do it.


****
Chapter Eight:

    I suppose the fear that she might quickly run through her ten masturbation sessions and then stop was what prompted me to take a gamble. The next time she took me into her room, she tried to lay down the law again. No touching, and you can masturbate if you want, but you cant come near me. Its not fair to make me suck you off and watch too, that wasnt what the bet was.

    But you enjoy it, I said.

    I do not. Im not a sick perv like you, I dont want to do any of this. The only reason Im doing this is because of this stupid bet. I wouldnt do any of this if you didnt force me.

    Id had enough. Fine, if thats the way you feel, how about a new bet?

    She started, not expecting that. What?

    Another bet. If you win, the rest of your obligation is off. If I win, we up the ante. I can touch you any time I want, anywhere I want.

    What? she repeated.

    You heard me. So, do you wanna bet?

    Wait, what do you mean whenever you want? Cause when blowjobs were whenever you want, I had to be, like, at your beck and call.

    That was a fair point. I wanted to make it easier for her to agree, so I backed down a little. Okay, anytime were alone, then. But you cant just run off whenever I lay a hand on you either, you take it until Im done with you.

    Good, because thats one thing, being some kind of sex slave, thats another. I guess thats okay. I bet youre going to keep touching me anyway, at least this way I have a chance at getting out of it. But the way she said sex slave, a little breathily, made me wonder. Maybe that was what she really wanted. She just wanted to be pushed into it. For one instant, I was absolutely sure of it.

    Or, perhaps, it was just what I wanted. I wondered just how far I could go with her, and I wasnt sure that Id stop until I found out what the boundaries were. If I could take absolute control over her, I would. I didnt really want to hurt her, but if she wanted that, and I wanted that, everybody was happy, even if I had to pretend to force her into it. You cant really force somebody into doing what they really want. But how would I know for sure whether she wanted it and just wanted to deny it, or actually didnt want it? I only had one idea. Arent you wondering what the bet actually is?

    Oh, yeah, she said as though it shed forgotten that little detail. So, what is it?

    A game. On the Wii downstairs. Your choice. The bet is simple I bet I win the game. I was better than her at most of the games we had, because I bought them, but there were still games where we were about even or where she usually beat me. I thought it would be a fair test of my theory. If she chose a game I was better at, or did poorly at one she was good at, it would prove to me, beyond any doubt, that she wanted it. Then it would just be a matter of pushing her where I wanted her to go until she started to push back.

    I didnt think I was risking too much. Even if I lost, shed already bet sexual favors once, I knew I could get her to do it again sooner or later.

    She went downstairs to the Wii console and began looking through titles. After a half hour, she chose a game that she was better at. It was the table tennis part of Wii Play. When we first got the system, she kicked my ass on that game right away, and although Id gotten better, she still beat me most of the times we played, and I spent most of my time playing newer games. I worried that I might have misjudged the situation. Youd better play your best, I said. Because if you lose, Im going to be taking full advantage of my newfound rights.

    We played. The game rules had the first player to 11 points win. She served first, and scored the first point because I missed, and then she scored another on the next round. Then I started remembering my old moves, and was able to gain ground.

    I have to think she let me win. It was too neat to happen otherwise. Throughout the whole match, shed let herself get 2 points ahead, and then shed start playing poorly and Id catch up.

    By the time she was at 9 points, we were tied. I scored the tenth point first, overtaking her for the first time, and on the next round she caught me again. It was down to the tiebreaker. Youre going down, I said. Or maybe Ill go down on you. I havent decided. I stuck out my tongue and lewdly wiggled it to demonstrate the pun.

    I served. It was a difficult shot, but by no means out of her range. She should have been able to at least return it and wed have some back and forth. She missed it entirely.

    No! she moaned, her eyes wide. She threw the controller down. If it hadnt been aimed at the couch, it might have broken from the force of the throw. How could I have missed that?

    Maybe you wanted to, I suggested.

    Dont be stupid, of course I didnt want to. What kind of sick person would want their brother to do stuff like that to them? Her eyes welled up a little, but I knew she could cry on demand. You just psyched me out, thats it. I got freaked out about losing and I played like shit.

    I had no sympathy. Id given her enough chances to win her way out of it. Whatever. I won. I patted my leg. Why dont you bring my winnings over this way.

    She slid over to me, head down, but hopped onto my lap. I leaned back and pulled her with me, running my hands over the exposed areas of her body, her legs, arms, and belly. Then I slid my hand underneath the shirt and up to her chest, fingers ducking beneath the bra. I squeezed her developing breasts firmly, getting a good fondle of each of them in turn, as my other strayed down to undo the button on her shorts.

    It popped open, and then I had one hand playing with a nipple, the other rearranging her pubic hair as she leaned back into me. She took it passively, not complaining, but not engaged, either. As I slid my left hand lower into her slit, I felt how moist shed become, further reinforcing my belief Id interpreted things correctly. If she didnt want it, shed be bone dry, and if she was bone dry, I dont think I would have pressed her. Instead, I rubbed, my fingers attracted by the wetness, seeking out the hole it came from. When they reached the source, I stuck two inside and curled them. Her butt was nestled up against my crotch, and she must have felt my erection pressing up against her, but she didnt complain about that, either. She just accepted it, letting me do whatever I wanted.

    I knew then it would only be a matter of time before I fucked her. I probably could have done it that day, if I pushed hard enough, but I wanted to take it slow, ease her into it one step at a time, and tease her a little. My secret goal was to get her to beg me for it, but if she was so fucked up that she needed to lose bets to get what she wanted, I doubted I could hold out long enough for that.

    If I couldnt have her beg, I was at least determined to leave her wanting more. I kept up a steady pace of stroking and fingering, until I thought she was getting close to the edge of orgasm country. When she reached that point, I withdrew my fingers, now soaked in her juices, and lifted her off my lap with both hands. Okay, thats enough.

    She stared at me uncomprehendingly. What?

    Thats enough for now. You can go. I picked up the game controlled, and started a new game, a single player round of tanks, pointedly pretending to ignore her.

    After a few seconds, she got up, and walked away on unsteady, rubbery legs, towards her room. Remember, I called back after her. No masturbating while Im not there. She didnt speak, and I smelled my finger and went back to my game.

    She held out an hour before coming back to get me. I want to masturbate.

    Yeah, I guess it was unfair of me to get you all worked up and not get you off, I said.

    It wasnt you, she insisted, but was unconvincing. I was watching my DVD of Twilight.

    Sure. Lets go, then. I followed her up to her room, smacking her bottom playfully as we climbed the stairs. Once there, she pulled off her shorts and sat down on the bed. You might as well get all the way naked, I said, Since Im probably going to be touching you anyway. Theres no reason to make it difficult for me.

    She frowned, and then removed her top, and finally her bra, then lay back, made herself comfortable, and started touching herself. She kept her eyes on me. I unzipped and pulled my cock out in advance, although I felt up her chest for a while before doing anything. When I did, I rubbed it on her breasts, teasing the nipple. Its too bad you dont have bigger tits, I said. Theres not even enough to titfuck here. She told me to shut up, so I let go of her, stepped back, and just kept watching.

    Soon, she closed her eyes and began to rub more vigorously. I leaned in for a close look, and then, as a surprise, stuck my tongue in past her frantically moving fingers and around her clit, and wiggled it. Id tasted one girls pussy before, but this one tasted much better, stronger than the remnants of her juices. It tasted a little like an apple that was just a little sour, but not unpleasantly so.

    The response to my little taste test was immediate. OH GOD! she cried. Her back arched up, bringing her pussy upwards, closer to my mouth, and the lick inadvertently became a kiss.

    Faith collapsed in a heap, her hands dropped to her side. Once she caught her breath, she said, You werent supposed to lick. Only touch.

    I was touching you with my tongue. You never said what I could use. I ran my hand into her red hair and ruffled it a little, and then left her lying naked. I didnt trust myself to masturbate in front of her without deciding to try then and there to fuck her, so I went to my room to do it alone.


****
Chapter Nine:

    Faith avoided me the next couple days, spending much of the time with her friends except when our parents were home, and either choosing not to masturbate, or to secretly violate the terms of the wager. I was worried I might have pushed things too far, but it was awful fun, and I knew shed be coming back to me eventually.

    One night, as we were having a family dinner together, in front of the television, Mom spoke up. Oh, I forgot to mention, your cousins called. Theyre back from their trip, and want to know if you want to come over tomorrow, go swimming or something.

    Sure, Faith said. I cant wait to talk to Lara about her trip. I thought it might be fun to see Lara too. Maybe Id get pussy that day after all.

    I have five cousins. Two live on the other side of the country. The other three of which live in my city. Todd, age 19, Lara, age 15, and Mikey, age 16. Theyre my Dads brothers kids. They live on the other side of town, in a nice neighborhood because, thanks to Aunt Sharons family money. Theyre a lot more well-off than we are. We hadnt seen them for a while, since they took a big trip to Europe right as summer started. It wasnt a special occasion, they go somewhere every year.

    Were not just cousins, were friends, at least most of us. Not as much with Todd, who tormented Mikey and I when we were younger and ignored my sister ever since she broke one of his models. But Faith was pretty close to Lara and looked up to her, and thought Mikey was funny. Im closest to Mikey. Hes like a much more awkward version of myself, and we got along well, like how brothers are supposed to be. Lara was a little different. I liked her, but Ive also wanted to fuck her since I was twelve which I guess makes her a little like my sister, only without the arguments. Sometimes I get signs Lara might be interested, but Id never made any move because she was family. If it didnt work out, things would get awkward. Well, now Ive already crossed that line with Faith. What was one more relative?

    The next day, I drove Faith there. I let her sit in the front seat this time, and she wore a skirt, giving me a nice look at her pale-skinned, unblemished legs, while reminding me even more of what was still covered. The access was easy. Wearing something like that was practically an invitation, and I accepted that invitation. When I drove along the secluded side streets, free of much traffic, I let my right hand cross over the divider between our seats, and up her leg. Underneath the skirt, she had panties on, but it didnt take much concentration to get underneath those, even while I was driving. I rubbed her pussy slowly, carefully. It was a little dry at first, but very soon became slick with her juices. In the mirror, I watched her face as little twitches played across it. She was trying to control her expression and not give me the satisfaction of displaying an effect, but her pussy couldnt lie, and her face didnt do it well.

    I must have fingered her for five or ten minutes on the car ride before I pulled out and drove the last few turns to our cousins place.

    My oldest cousin Todd answered the door. He was a fairly built guy who had a small weight bench in his room, and talked about it a lot. He wore a tank top and shorts, and had sunglasses on a chain around his neck. He was superficially nice, welcoming me in and shaking my hand, but he always squeezed a little too tight and I still had those lingering memories of him beating up me and his brother when we were younger, so I didnt like him much.

    He asked how we were, took a look at my car, subtly insulted it compared to his own BMW, and then pointed us towards the backyard.

    Lara was sitting on the edge of the large pool. She was blonde, and her skin was more tanned than usual, undoubtedly due to a lot of time spent on European beaches. She wore a yellow bikini that clung tightly to her pear-sized beasts. I could see tanlines poking up from the bottom part of her swimsuit, but there were none on her bikini top. I imagined her sunning herself on the beaches of Europe, where toplessness was supposedly okay, and cursed that our family was never invited along.

    Mikey was on the diving board, looking ready to jump off when he saw us. He looked about as usual, except with his hair wet instead of poofed up. He looked like the before picture to his brothers after, in some kind of ad for a weightlifting program. There wasnt much fat on him, but not much muscle either. If I had the same type of features as them, I could have been there too, somewhere in the middle ground between them, maybe as an example of the benefits of the program after only a few weeks. Mikey waved and cannonballed into the water with a big splash, then swam to our side of the pool.

    We exchanged greetings, talked about their trip a little, and then changed into our swimsuits. I had long swim trunks and only needed a second. Faith, being a girl, needed longer. She eventually came out, wearing that green bikini she once wore half of in the shower with me. I almost got a boner from the memory alone, not to mention how she looked in it.

    We swam a while, played some two-on-two water basketball (in which I got to accidentally grab Laras boobs while trying to steal the ball), had some pizza rolls and colas, and just generally spent time together. We mostly stayed in our swimsuits, even when we were inside. With that much flesh to look at, my gaze kept falling on either my sister or Lara, distracting me from talking to Mikey. I dont know if he noticed. I think he was distracted too.

    One incident had Mikey and I talking about some sports, and I could barely follow his side of the conversation, because on the other side of the room Lara and Faith were talking about her dance lessons. Then they got up and Faith demonstrated to Lara something, raising her leg very high, like you see in ballet. Lara tried to copy the move. Having both of them in tight bikinis, raising their legs provocatively was quite a sight. I noticed Mikey had gone silent too.

    Lara lost her balance and stumbled, laughing. I dont think I have it in me to do that.

    Im sure you can be flexible enough, Faith said. You just need a little training. I could just imagine. Id love to help her with her flexibility by pinning her legs behind her ears until she got used to it while I fucked her.

    Maybe, but the choreography for your stuff is too rigid and complicated. I prefer spontaneous, freestyle. She moved her body sexily in a music-less dance.

    Its not so bad. I like it. Sometimes its nice to just not have to make any decisions, you know? You just do what youre supposed to do when youre supposed to do it. Thats all. If you do exactly what youre told and they dont like you, its not your fault, you were just told the wrong thing.

    I must have spent minutes watching, imagining. I had loads of wrong things I wanted to tell her to do. Eventually Mikey got my attention and once again drew me into a conversation about the teams we followed.

    A half hour later, after wed returned to the pool to do a little more swimming, Todd came down from his room and met us there. Hey, Im going to grab a coffee, you guys want anything?

    Lara wanted an iced cappachino. I asked for an iced coffee with three sugars. Mikey wanted something to eat, asking for a combo from a sub place near the coffee shop, which prompted Lara to ask for a sub too. Okay, Im not going to be able to get all that. One of you guys have to come with me.

    Lara volunteered. She hadnt dropped back into the pool yet, so was still dry, and just pulled on a t-shirt and shorts and left with her brother, to my disappointment. Once they pulled out of the driveway, Mikey got out of the pool and said, Im going to go inside for a while, maybe watch a movie or something in the basement. Want to come, Mark?

    I knew what he was up to. Since we were young, sometimes wed sneak down to the basement and watch porn on one of his dads satellite channels. I looked across the pool at my sister, who was shooting some basketball shots by herself. The backyard was well obscured from prying eyes, with a high fence and lots of trees. Why dont you go ahead, I said. Ill join you in a few minutes.

    He looked at me funny, but left. I slipped into the pool and behind my sister. She hadnt noticed we were alone. I slid my hand under her butt, attacking her from below, and she yelped. Mark! she whispered, looking about frantically. Not here.

    Shhh, I said. Nobodys watching. Were alone. Just relax. Im collecting on the bet. I felt her up there, in the pool, for about ten minutes, keeping an eye on the sliding glass door to the house, before I heard Todds car pull back in. My finger withdrew and Faith swam away from me quickly, blushing a deep red.

    I got my coffee and also grabbed Todds sub combo and brought it to him downstairs in the basement. There was no porn on the screen. He was looking at me strangely. I passed him his food. Here you go, sorry I got a little held up.

    I saw what you were doing with Faith, he said.

Chapter Ten:

    I froze at the accusation, then decided to try and play it off as though it was no big deal. Maybe he was referring to something else entirely. What do you mean?

    You were, like, feeling her up. I saw you from the upstairs window.

    Oops. I guess even the best of us slip up now and again. So, what, you never fingered your sister?

    No! he said. He leaned close to whisper. Are you doing her? He didnt sound angry or freaked out. He sounded interested.

    I relaxed. Not yet. Probably soon, though.

    How could you do that?

    Its a long story. Just, keep your mouth shut. Its not like were dating or anything, just having a little fun.
    Thats messed up, man, he said, but he said it with a smile and a shake of his head. Man, I wish I could get a piece of that.

    I thought about it. Why not? If I could get her to fuck me, I could probably get her to fuck her cousin. Tell you what, keep your mouth shut, I may be able to get her to do something with you.

    Really?

    I nodded. You know Id like to help you out. I might be able to get her to at least throw a bj your way. No promises, but Ill do what I can. Just, you know, maybe put a good word in with your cousin for me, because Id like to get a piece of that, too.

    Sure I mean, Ill try.

    On second thought, I said. Dont say anything to her. You might screw it up. But Ill still try to help you. It wasnt just charity, or angling for his own sister that made me the offer. The thought of Faith fucking another guy not because she wanted to but just because I wanted her to really aroused me. If she wanted to be controlled, well, that was pretty controlling. I wanted that power, if she wanted to give it up. I wasnt sure if she was willing to go that far, but I was dying to find out.

    I was telling Mikey a little about what shed already done for me, when I had to stop suddenly. The door was opening. It was my sister. She sullenly padded down the stairs and said, Im not really feeling well. Can you bring me home?

    I was suddenly worried. Sure. Whats wrong?

    I dont know. I think maybe those pizza bites didnt agree with me.

    I told her I would, and we said our goodbyes to our cousins, and I drove her home. Do you want me to pick up some Pepto or something? I asked on the way. I really was concerned for her.

    No, she said. Im not really sick. I just wanted to go home.

    Oh? Why? You and Lara have a fight?

    No, she said. Then she sighed. I suppose youre going to find out anyway, since I have to let you be there. I really need to masturbate.

    Spectacular. Oh? I guess you liked being touched.

    I cant help it, she said, her blush extending all over her face and blotting out her freckles. Dont be too proud of yourself, a monkey could touch me there and it would feel good.

    Wow, I said. Kinky. Do you often think about animals doing sexual things with you?

    Shut up!

    Because I dont know anybody with a monkey, but my friend Fred has a dog

    Shut up, you freak! Youre so disgusting.

    Throwing caution to the wind, I darted my hand under her skirt to feel her up. I dont know, youre pretty wet. I must have said something that turned you on.

    Thats from the pool.

    Right. Well, dont worry, well be home soon. Ill help you get off.


    She ran up to her room. I let her go. I made her wait a few minutes while I killed time downstairs. Finally, she yelled, Are you coming?

    Pretty soon, I said. Are you? Oh, right, youre not allowed to until Im there.

    Come on she said. I decided to be nice. I was pretty horny too.

    She was already nude, waiting for me in her room. She sat on the edge of her bed, and as soon as she saw me, she put her fingers to her crack and began rubbing. I put my hands on her shoulders and pushed her down into a lying position, and began caressing her lightly, then knelt over her pussy and tongued along the side of her slit as she continued to fuck herself.

    She was getting into it pretty good, and my dick was rock hard, so I decided Fuck it, it was time. She wasnt likely to ask, so it was time to push her a little more. I knelt between her knees and gently spread them apart, then rose and took my cock out. It was pointed directly at her little cunt.

    What are you doing? she said breathlessly.

    What does it look like? I asked. I leaned in closer and touched her pussy with the head of my penis. Touching. Like Im allowed to.

    You cant fuck me, she said. Theres a difference between touching and fucking. The deal doesnt let you fuck me, she said. She wasnt stopping masturbating. If you try to fuck me, Ill have to tell somebody.

    Okay, I said. But what about rubbing? To demonstrate, I rubbed the head of my penis along her slit, in the groove, poking gently but too gently to penetrate inside. Theres nothing wrong with that, is there? Thats still touching.

    I guess not, she said breathlessly.

    Good. I used my thumbs and pulled her pussy a little wider. My cock slipped in between the lips, and I pressed forward just the slightest bit. And what if I just have the head in a little? I asked. Thats not fucking, is it? She didnt answer, but stopped masturbating and drew her fingers back to give me room. Very slowly, I moved more and more inside. If she told me to stop, I would have, but she said nothing and only watched. Soon, the whole head was inside her. By some measures, this was penetration, and she was no longer a virgin. I didnt dare move forward beyond that, not yet. Well? Is this fucking?

    No, she said. I guess its not.

    Im glad. But I think we really need to decide where touching becomes fucking. Because, I said, giving her an intense, uncompromising look, I intend to touch you as closely to that line as I can. So you need to tell me exactly where it stops being touching.

    We stayed like that, silent, unmoving, lightly coupled, for a pregnant twenty or thirty seconds, before she finally made a decision and said, I think once youre more than halfway inside of me it starts being fucking.

    Id take halfway. But now, I pulled out, her cunt lips, stretched around the head of my penis, seemed unwilling to slide back, but they did. I walked over to her desk, cock swinging with every step, and got a marker, then handed it to her. Just to be sure, wed better mark it. Mark the halfway point on me. I wont go any deeper than that. I swear.

    She held my dick lightly with one hand, and looked at it, unconsciously licking her dry lips, and then pulled me close, and made a mark on the side of my penis. It was more than halfway down. By my reckoning, it was somewhere well in the neutral zone between halfway and three-quarters of the way down. I took the pen back from her, marked it around so I could see it from above, and then tossed it back on her desk.

    Okay. Lets get back to not fucking you then.

    I resumed my previous position, only this time after I got my cock head in her hole, I held her legs in my hands for leverage, so I could pull her to me while pushing in, and I began to pump in and out.

    I was fucking her. Id say I was, I think most people would say I was, but I did play fair with her. As hard as it was not to dive all the way in to the balls, I did not cross the line marked on my penis. So as far as she was concerned, I was only touching her inside her pussy, and with my dick.

    As I plowed in and out of her snatch, increasing in speed, she brought her fingers back to play with her clit. She must have been very near to cumming when I chose to act, because soon she was moaning and writhing, then repetitively moaned, oh god, each time increasing in volume and pitch and length. I came just before she did, squirting my cum deep inside her, up towards her womb. I hoped she was protected.

    I left myself inside of her until Id stopped dribbling, and then pulled out. There. That wasnt so bad, was it? She didnt say anything. I think Im going to be doing a lot more touching from now on...


****
Chapter Eleven:

    I touched the inside of Faiths pussy with most of my cock the again next day. That time, she got on her hands and knees, and I did it from behind, my hands on her ass, getting a good look. She didnt even touch herself this time, just let me take it. As I rocked back and forth into her (up to the line, freshly marked again at roughly the same spot) and kneaded her ass cheeks, I told her how it looked like a tight ass and I might like to touch it one of these days. She didnt say anything, not even a complaint, but moaned a few seconds later. I knew I was getting to her. I knew, sooner or later, shed ask me, instead of just going to masturbate as the bet stipulated and getting touched while she did.

    As it turned out, she didnt ask, but she did almost the same thing while trying to preserve her deniability. The next time I fucked her, I decided not to wait until she came to me to masturbate. She wore a pretty short skirt, and walked by me while I was watching TV. Her little pale legs crossed my vision and I thought I saw a flash of panties. I got stiff, and since nobody was home, I decided to assert my rights. Come here a minute, I said, and pulled her towards me.

    I felt up her legs and into her panties, then pulled the fabric down to her knees. While I was seated and she stood in front of me, I had a nice view of her puffy little pussy and I felt like a taste, so I leaned forward and tongued her crack for several minutes. When Id had enough of eating pussy, I stood, told her to lie on the couch, and took off my pants as she complied wordlessly. She even took her panties completely off without having to be asked, because she knew what was coming.

    The mark was still visible from the last time since the marker we used was semi-permanent, so it still made a good reference point. I stuck the head of my penis in, and then slowly got as far as was allowed to go.

    I thrust in and out, in and out, enjoying her squeezing the top half of my cock tight. After a while, she linked her legs behind me and her heels dug into my back.

    It wasnt a gentle nudge of inadvertent movements. She was pulling me deeper inside her, and I was already as deep as I was supposed to go. An invitation is an invitation even if its unspoken, so I went with the flow, let her pull me in, and sank all the way into her. She let out a moan of pleasure, and I thrust in and out, letting my balls slap against her. I fucked her as hard as I could and as long as I could, then pushed one last time as far as I could into her as she gasped, and let jet after jet of my sperm shot into her pussy.

    Well, I guess youve been officially fucked now, I said.

    You bastard, she yelled. You werent supposed to do that. Tears were in her eyes, and for a moment, just a moment, I felt ashamed.

    Then I remembered the feel of her legs drawing me in, and I just got mad. I grabbed her face in one hand, squeezing just enough to make her pucker up and shut up. Dont you dare try to blame this on me. I was only doing what you wanted. Everything Ive done, youve gotten wet from or gotten off from and thrown off signals that you wanted more, all while complaining that you didnt want it. I see right through you. Inside youre just a dirty little slut, arent you?

    I let her go enough to speak. I am not, she said, but it was a weak denial, like she was trying, and failing, to convince even herself.

    You lost that last bet on purpose because you wanted it. Fuck, I bet you lost all of them on purpose, didnt you? She didnt answer, but couldnt meet my eyes. I had her, I knew I had her. Okay, then Ive got one more bet for you. This ones for all the marbles. If I lose, I never touch you again. Ever. No matter how much you want to cum, no matter how much you beg. If I win, youre my sex slave until the end of the summer. You do whatever I want, whenever I want, with whoever I want. Her eyes got suddenly wide at the last part. It looked like they were about to jump out of her head. Now, do you wanna bet? Or do you want to keep things as they are?

    Whats the bet? she asked softly.

    Sometime in the next five days, you will beg me to touch you.

    Thats it? she asked. But thats so easy.

    Im not finished. Youll beg me to touch you, because you cant do it yourself. If you play with yourself in any way, whether you use fingers or toys, or even squeeze your legs together and rub your thighs, you lose the bet. Ive gotten you used to regular orgasms, so its time to turn off the supply, until youre mine, totally.

    Her mouth hung open a little, and I watched her wet her lip with her tongue, thinking it over. Okay, she said. I can do that.

    I thought it was a fair bet. I could hold off touching myself for five days. Girls should have it even easier. Of course, I had a little idea to help me win, but if she really wanted to, I thought she could have made it. I gave her the official handshake to seal the agreement, and once it was given, I let her go. Let the game begin


****
Chapter Twelve:

    I didnt do anything with her the first day. I wanted to see if shed just come to me on her own, like I wanted her to. Besides, I had to work that day. I dropped by her room when I got back home to see if she might ask then, but she wouldnt.

    I let the next day pass, too. I treated her like a normal guy would treat his sister, in the hopes of giving her a taste of how boring our relationship would be from then on. She mostly ignored me, which was pretty much as our relationship had been before the Samuel L. Jackson incident.

    By the third day, I was starting to wonder if my theory was wrong. It was time to kick things into high gear. I saw her in the kitchen, laying out some carrot sticks on a plate for breakfast. Mom and Dad were both gone. She tensed for a moment when she saw me, then relaxed. Once she let her guard down again, I came up behind her and reached into her shorts. What are you doing? she asked.

    I never gave up my right to touch, I said as I worked my fingers past her panties. As she bent forward, pushing back into me, I grinded my crotch towards her ass. I kept her like this for several minutes, and then when I heard her breathing heavily, and regularly, almost panting, really, I abruptly pulled out.

    Arent you going to she asked, but then stopped.

    Do you want me to? I asked.

    She shook her head, and left for her room. I stood outside, waiting, to listen for any sounds of masturbation that would constitute losing.

    Every time I saw her that day, if we were alone, I felt her up for a few minutes, to get her motor running, and then suddenly left.

    The next day, I went into her room and told her to lay down on the bed. She did, meekly, almost as though she was already mine. I stripped her down to nothing, and began fingering her. When she started wiggling with excitement, I added my tongue to the mix, teasing her clit with little licks. I had to be careful. Every few seconds I would look up to watch her face. My plan might be ruined if I accidentally made her cum.

    I stopped when she was close. She groaned in frustration when I told her that was enough, that she could get dressed. What? Do you want me to touch you more?

    She didnt answer.

    I left her alone a few hours, then did it again, only this time, after licking her, I pulled down my shorts and ran my dick along her slit, then pushed it inside. I was worried Id overplayed my hand, and if I was going to lose, Id get my dick wet a few more times. Id save all out fucking (or the half-way fucking I was technically entitled to) until the last day, but I gave her a few strokes, In and out, while playing with her clit with my thumb, and started to leave again.

    No, she said as I was at the door.

    I paused. What?

    Its not fair.

    I shrugged. Then you shouldnt have agreed to it.

    She was quiet for a long time, and I reached for the doorknob. She spoke again before I turned it. You wont hurt me, would you, Mark? If I lost?

    I looked back at her and smiled. Im your brother. Of course I wouldnt hurt you.

    She sighed. Okay. You win. Please touch me.

    Her last question made me generous, I gave her one last test. Are you sure you want to do this? You know what this means?

    She nodded. Anything, anywhere, with anybody.

    And you still want me to touch you?

    Yes. Please. Im begging you.

    Id won. It felt like a wave of pure power washing over me, through me. I dont think Ive ever felt anything more arousing. Oh, Ill do more than touch you, I said as I went back to worked my cock into her slick hole once more. I grabbed her by the ankles and lifted them up to my shoulder, then back, seeing just how flexible she was. I pinned them in the spaces between my shoulders and pecks, leaning on top of her to get a downward angle. I wasnt able to pin them back to her ears, but I didnt think her dance teacher would have any complaints about her flexibility.

    I repositioned myself inside her, since Id temporarily slipped out, and then pushed all the way into her, practically stabbing her with my dick. Her legs pushed back, but not by much. I fucked her roughly not harshly, I wasnt trying for pain, but her comfort wasnt my priority then, getting off was. I was so worked up from the last few days that I didnt care much about her pleasure, I just kept thrusting and thrusting, like I was a machine designed to make my dick expel its seed. I broke stride just once to wipe some of the sweat from my head. She used the opportunity to let her legs slip out, falling towards sideways. That put her in a spread eagle, but allowed me more room to get deeper, so I didnt adjust any. I felt a throbbing up and down my shaft and it wasnt just her tight pussy squeezing me. It wasnt long before I came inside of her. She had an orgasm too, but I think she was so close already that practically any stimulation would have pushed her over the edge.

    I grunted as I emptied myself inside of her, then pulled out and let the last jet fall on her face. She was still coming down from her climax, so I wiped grabbed my panties and wiped my cock down with them. I thought Id get a kick out of making her wear them later.

    So what now? she asked as I sat down on the bed beside her. I looked into her eyes. She wasnt crying. She wasnt smiling, but she wasnt crying. I watched her, looking for any sign of pain, worry, or doubt. Now that Id just gotten off, guilt was once again an emotion I was capable of. When I didnt answer her question, she must have taken it for a criticism, because soon Faith corrected herself. I mean, what now, master?

    Master. I grinned, loving the sound of that. It looked like I had myself a sex slave.


****
Chapter Thirteen:

    I made good use of Faith, keeping my word that she would be my personal sex slave. Any time I got horny, I used her. The next day, I took her anal cherry as she grunted with her face jammed into the bed, and it was impossibly tight, but I liked cumming it in her pussy better, and I didnt want to risk giving her some kind of infection by going from one to the other. I still loved my sister, and I didnt want to hurt her, and I got the feeling that anal sex did that, even though she was a trooper and didnt verbally complain. She seemed relieved when I told her it wasnt as good as Id hoped.

    After a few days of enjoying her all by myself, and wearing myself out a little in the process, I decided it was time to hold up to my end of two promises. I said that Id try to help Mikey get a shot with Faith, and I told Faith shed do whatever I want with whoever I want. She clearly wanted that, or she wouldnt have agreed, so there was no reason to disappoint either of them. One day, while Faith was sucking on my cock dressed only in panties, I phoned Mikey.

    After the initial pleasantries, in part designed to make it clear to her who I was talking to, I told him, casually, as though it was just another bit of news, Yeah, so I started fucking Faith. She almost choked on my cock in surprise, but didnt do anything except look at me with wide eyes. I reached over to pat her head, a signal to go back to moving her head up and down.

    Wow. How was she? Mikey asked.

    Real good. Do you want to fuck her?

    Do you think she would?

    She will if I tell her to. She lost a bet. She has to do whatever I say.

    There was silence on the phone for a few seconds, and then he said, I dont know, if shes only doing it because youre forcing her

    Im not forcing her. Shes kind of a freak. A beautiful, amazing freak. She wants it, or she wouldnt let it happen. I can get her to fuck you, easily. She knows thats the plan, and she certainly hasnt had any complaints. She looked me right in the eyes as she went from the top of my cock all the way down, as though to emphasize that she wasnt objecting. I smiled lovingly at her.

    Okay, then, yeah, Id like to fuck her.

    Good. Heres the deal. Ill throw you a blowjob for free, because youre family. You can see her naked, even feel her up a little. But to fuck her, I want money. $100 a pop, so to speak.

    $100? Thats sick dude.

    Believe me, shes worth much more. I know you can get it. They were practically spoiled with their allowance. He might have to ask his parents for a little extra cash, but theyd do it if he gave them a plausible story. He probably had money saved up already to buy a car or something if his parents hadnt already promised to get him one when he got his license. If youre free, well come over tomorrow and you can sample the goods.

    He agreed, and the next day, I drove Faith over to her place. She wore a skirt and, when we pulled up into the driveway, I had her roll her panties down her legs in the front seat and pass them to me. Mikey would be alone that day, he assured me, and I got a little thrill knowing all it would take would be a flip of the skirt and shed be exposed.

    Mikey met us at the door, and tried to act all casual, like it was just another visit from her cousins. Faith kept her head down, but I knew she was secretly eager. Her panties were pretty damp. As soon as we were inside, I pulled up the front of Faiths skirt and said, Hey, Mikey, check this out. Her little slit could be seen clearly, and Mike had a boner visible through his shorts. I dont think he ever completely believed me until that moment.

    Holy shit. We should go downstairs, Mikey said.

    Downstairs, I sat down beside Faith on the comfortable black couch. She had her legs pulled up beneath her, and I directed her to spread and display for him. She did, with only her blush giving any indication that she wasnt 100% behind this.

    I let Mikey kneel down, get a good look, stick his finger inside. He was clumsy, like I was the first time. After hed fucked around enough, I said, So, you got $100 for me? Or are you going to happy with a blowjob?

    Are you all right with this, Faith? Mikey asked.

    Yes. Whatever Mark wants me to do, she said. She even smiled. Hes my master. I didnt think Id ever get tired of her saying that.

    He chose to fuck her, of course. I waited until I had the money in my hand, counted it, then nodded to Faith. Go on, make him happy, girl, I know you can.

    He went for straight missionary position. I watched them together, getting a little aroused, but I didnt want to whip it out and fap. Fapping to your sister is fine, fapping along with your male cousin to porn is fine, as long as you both kept your eyes glued to the screen, but fapping while watching your male cousins cock plow into your sister just seemed a little gay.

    He mumbled about how he wanted this for so long, but after only about two or three minutes, he came and pulled out, exhausted. We left soon afterwards. I could tell Faith was disappointed the sex wasnt longer, but Id take care of her later.

    On the way home in the car, I took one of the twenties and held it towards Faith. I dont have to do this because youre mine, and Im not promising to do this every time I rent you to somebody, I told her, stopping for a moment to let that sink in and assure her more was coming, before continuing, but you did a good job, so I thought Id reward you. $20 isnt bad for two minutes work. She took it in trembling fingers, and then after she put it away, she smiled.

    Thank you, Master.

Chapter Fourteen:

    Mikey wanted another dose of Faith a few days later. He called me, told me he was going to be alone for a few hours, and had money, so I made another drive over with Faith.

    This time I let him fuck her before asking for the money. That was, generally, a policy I do not recommend, but it worked out for the best this time.

    He had her ride on top of him this time, cowgirl style, letting her do most of the work while he took in the view. I, meanwhile, got a view of her little ass bumping up and down.

    He lasted longer this time, maybe five minutes, and swore up a storm in his moans and grunts, which was funny compared to the last time when he seemed deadly serious and focused. After he came, I told Faith to get off and clean him up, which meant licking off the combination of cum and her own juices that were left on his cock.

    Okay, I said, after she was done. I guess you owe me $100.

    Mikey put on a guilty look. Listen, I was only able to get $45.

    What? You told me you had it all. I was not impressed.

    I thought Id have more, but it just didnt work out. Besides, $100 is way too much.

    Now I was outright angry. Too much? First you try to cheat me, and then you insult Faith. Thats not cool man.
    He put up his hands defensively. Thats not what I meant, its just she enjoyed it. I know she wanted it. He looked at her. Didnt you Faith? You wanted it, right? he pleaded with her. Fuck, he was practically begging for her to agree.

    I didnt let her answer. It doesnt matter if she wanted it or not. Come here, Faith. She hopped off the couch and to my side. I put my hand to her cunt, trying to ignore that Mikeys cum was inside. This pussy belongs to me. It does what I say. I was doing you a favor by offering to share it. Fuck, I even threw in a blowjob for free, because youre family. You try to screw me, and youll never be screwing this, again. I dipped a finger in.

    I felt Faith squeeze around my finger reassuringly. Then she said, Hes right, Mikey. I wouldnt do your if Mark told me not to. I dont think Id do you at all if he didnt tell me to. Pay up. Good girl.

    I didnt say I wouldnt pay, Mikey backpedalled. I just cant pay right now. Give me a week or two. Mom wont give me any more money until my next allowance.

    You have till tomorrow, I said. I was pissed at him. And never again are you getting credit. You want me to tell Faith to fuck you, you pay up front.

    I need a little more than that. Give me a till the weekend, I cant do it in a day!

    Tough. Sell something. Youve got enough nice shit, somebody will pay you for some of it. And until you pay, Im taking your laptop as what do they call it collateral. Go get it. Faith, get dressed.

    Come on, man, Mikey said. Not my laptop. I use that all the time. Ill get the money for you by tomorrow. You dont have to be such a prick about it.

    He was in very real danger of severely ruining our friendly familial relationship for all time. I might have banned Faith from fucking him at all, just for the insult. However, he got extremely lucky. We all looked above us at the same time at an unexpected sound. Above us we could hear the rhythmic thumping of somebody running upstairs. The door opened, and Mikeys sister Lara came bounding down the stairs.

    Wed only had a few seconds warning, so although Faith was able to get panties on, and Mikey had one leg in his pants, there was no mistaking that we were pretty well naked. What the fuck is going on? she asked.

    I thought you were out! Mikey said with an accusatory tone. You left with Todd!

    No, Erin cancelled. I just took a nap. Then I saw Marks car in the driveway.

    We were just Mikey started. I dont know what line he was going to use. It probably would have been dumb.

    Lara interrupted him. I know what you were doing. I heard it all through the vent.

    What vent? Mikey asked.

    The one in my closet. If you bend down and everything elses quiet, you can hear almost everything going on in the basement. I thought you guys would be jacking off to porn again. She looked to me. Is it true?

    That we were jacking off to porn?

    No. That youre pimping out your sister.

    No, I said. It was my turn to be defensive. Its not like that.

    We werent doing anything, Mikey said.

    Right. I heard you guys fucking. She mimicked his voice, and his words. Oh, Faith, this is amazing, youre so fucking tight. I dont care if you fuck her, I know youve wanted that for years. Is the other stuff true?

    I didnt know what to say. Faith answered for me. Marks my master. I do what he says.

    Does he have something on you? Like blackmail?

    We made a bet. I lost.

    She didnt need to explain any more than that. Lara, too, know how our bets worked, and didnt seem surprised that it had gotten to this level. She looked back to me, deadly serious. So how much if I wanted her to eat me out?


****
Chapter Fifteen:

    I grinned, feeling that now familiar feeling, relief mixed with the certainty that everything was going to work out all right. For you, its free. So long as I get to fuck you, first.

    She smiled, a devilish little smile out of only one side of her mouth. Took you long enough. I was beginning to think you were never going to ask me. She pulled her shirt over her head, and then looked over at her brother. Go upstairs, Mikey. I dont want you sitting there and staring.

    But

    You still owe me money, I said to Mikey. Why dont you go and check under the couch cushions or something. Or see if you can find something thats worth $55, used.

    He gave up his arguing, and started a slow march up the stairs. When he was gone, and the door to the basement was closed, I said, Ten bucks says hell be racing up to listen at the vent.

    Probably, Lara said in a smile. But fuck him.

    Fucking him wasnt exactly the plan. I took off my shirt.

    Lara unhooked her bra and slid it off her shoulders, revealing her nicely tanned teardrop-shaped breasts. Her areolas were larger than Faiths, and faded more gradually into the rest of the breasts, but the nipples stood just as alert, erect. Soon she was nude, having dropped first the shorts, quickly, and then the thong-style panties in a slow tease, letting me look at her from behind. Her ass was pretty nice, as was what I could see of her pussy. I decided that I wanted to take her doggy-style.

    She seemed to favor missionary, for she sat down and spread her legs wide. She had a visible tan line area around her pelvis, that part of her skin standing out almost white compared to the rest. Her pussy was almost bare, with what looked like a little bit of growth coming in after a recent shave, just enough to give a triangle of dark shading on the creamy white larger triangle of untanned skin. Laras slit was a little more open than Faiths, with a fair bit of pink and the hole clearly defined by inner lips. It looked good either way, but better from the back than the front. When shed bent over to remove her thong, her legs squeezed it tight, and I just wanted to use my cock to push it apart.

    Faith, I said, why dont you go down on her a little and warm her up. Just lick her like you like to be licked.

    Yes, Master, she said. That title always got me hard, but I was already hard with the thought of fucking my cousin. I moved off to the side where I could get a good view and slowly finished stripping down. Faith walked the first few steps and then got down on her hands and knees and crawled to close the distance to Laras pussy. She looked at it closely, and I thought for a moment that she was going to balk you never know whats going to be the last straw for somebody. But Faith was a real great slave, and soon her tongue lanced out to take a lick. At first she didnt move the tongue much, but instead kept it steady and moved her whole head back and forth, up along the slit, like it was an ice cream cone. Lara assisted by holding her labia wide open, giving Faith more access to the pink parts inside. By the time I was naked, her tongue got more adventurous, and it flicked around her clit while Lara made sounds like she was enjoying a particularly delicious meal.

    I watched it for a few minutes before I couldnt take it any more. Okay, Faith, I said, and swatted her lightly on her panty-covered butt. Thats enough for now, its my turn. When she moved out of the way, I told Lara, Bend over.

    She frowned a little, then got up, turned around, and bent down, resting her arms on the couch and presenting me her ass. I stuck a finger in, feeling her wetness, and then used the hand to position my dick so that I could thrust inside without difficulty. I did just that moments later, while grabbing her by the hips. With one swift movement, I was all the way in.

    It was disappointing, but only by comparison. Faith was so tight fucking her was like an all-over cock massage. Lara was more like a warm, comfortable, hug on my dick. Still nice, but theres a world of difference. I thrust in and out for almost a minute, pushing hard inside of her, and kept looking over to Faith, who was watching it with her tongue playing around the bottom edge of her upper lip. I had an idea, and pulled Lara upward. Come on, I said.

    I wanted to change position, trying to do it like they do in some porns, without losing contact, but I slipped out when she stood up. So I just turned us around together, and then fell back onto the couch, her ass on top of me. A quick readjustment later, and I was back inside her, she bouncing up and down on me. I pulled her back to me so I could look over her shoulder, and then told Faith, Lick us together.

    I leaned Lara back so I could watch over her shoulder while Faith eagerly added her tongue to where we joined. It was incredible, combining the best part of normal and oral sex, the powerful thrusts as I went in and out of my cousins pussy, and the feel of my sisters delicate, warm tongue snaking its way around us. She licked both of us, and it seemed when she was on Laras clit, Laras pussy convulsed, squeezed me even tighter, so it didnt matter to me where she was focused.

    A gentle kiss on my cock was what triggered the final sensation that would lead inevitably to my orgasm. I started ramming more and more intently and grabbed Laras tits. The sudden onslaught of effort began to make her cry out in pleasure. Finally, when I was ready to blow, I held her down on top of me. I came deep inside her while Faith kissed my spasming balls.

    I slipped out of Lara, and immediately Faith pulled my gooey, deflating cock into her mouth and sucked intently as though demanding the last drops of my seed as her right. I let her, then pointed at Laras crack. A lot more of my cum was still up there, and some of it was leaking out. Now that youre done cleaning me, I said, you should do the same for your cousin.

    My dick dropped, and Faith buried her face in Laras snatch, sticking her tongue way up inside, and Lara started moaning lightly again. I slipped out from under there. My cock was quickly growing flaccid and I didnt want to that to be the last impression it left on both of them, just lying there limp in the background while Faith ate Lara out.

    After quickly slipping something on, I knelt by Faith and rubbed her bare back while getting a good view of her performing her task. Thats a good girl, I said softly. Get all that cum out of her. Her mouth was pressed tight to the hole for almost a minute at a time, and from Laras gyrations I knew she was doing good work. It wasnt long before Lara closed her eyes and let her head loll back. She went limp soon after. Faith kept licking for a while, until I patted her and told her she could stop. She sat up and smiled, her face wet with Laras juices.

    Wow, Lara said at last. That was pretty fucking good. We should definitely do that again.

    I think that could be arranged. I looked over at Faith, who seemed happy. The fingers of one of her hands were playing inside panties, inside of her pussy. I think Faiths still unsatisfied, I pointed out. You feel like eating her out?

    Lara wrinkled up her nose and shook her head. No, sorry. Im not gay. Besides, my brother just cummed in that, theres no way Im sticking my tongue in there. Thats pretty gross, you know? To lick up your own brothers cum? Youve got to be some kind of fucked up freak slut to do that.

    Hey! Faith cried in wounded dignity.

    I shot back a lopsided grin at Lara, knowing she was only teasing, but Faith seemed to take it seriously, so I had to jump to her defense. Hey now, thats my sister, and my property, youre talking about there, and Im not going to let you insult either of them. Say youre sorry.

    Lara pouted, but said, Im sorry, Faith. But Im still not licking you.

    Its okay, Faith said.

    I bent down beside Faith to look her right in the face, then smiled at her, brushing a lock of hair behind her ear. As I retreated, I stroked her cheek gently with one finger. You want to get off too?

    She nodded eagerly. Yes please, Master.

    Fingers? I asked. Or can you wait for my cock?

    Please, I want your cock, Master. She pulled her fingers out of her pussy, as though it was an unspoken promise to wait.

    Faith had finally begged me to fuck her. I was just sorry that Id just cum and couldnt do it right then. Impulsively, I gave her a kiss on the cheek, and she blushed. Give me about ten minutes, Ill take care of you. I couldnt very well let my sister go home unsatisfied.

Epilogue:

    Despite Mikeys douche move this time around, I managed to forgive him, though from then on I got my money up front. My cousins, including Todd, a few weeks later, turned out to be some of my best customers, although they were by no means my only ones. Faith was a popular piece of ass, and she was mine to sell one piece at a time.

    It wound up being a pretty great summer for me, and I think Faith enjoyed it too. I was able to quit my job, as I made more money pimping her out than I could have working. I could have made a lot more by being less discriminating, but I cared about my sister and didnt want to risk her getting hurt. I didnt let her go with just anybody, only friends and family. I also took cues from her. If it looked like she didnt want to do someone or something, I usually refused on her behalf, and if she didnt seem to enjoy it, I told her I wouldnt let her do that again. Plus, absolute secrecy was a condition of anybody getting pussy. I didnt want anybody outside finding out what my sister was doing and ruining her reputation. So, you see, I was being pretty responsible with her.

    Thats why I say what happened wasnt all my fault. It was a little my fault. But Mom, Dad, Samuel L. Jackson, the people I pimped her out with, and Faith herself for agreeing all share in the blame. It wasnt all me, no matter how guilty I felt over what happened.

    What happened was Faith missed a period, in the last week of summer. I should have seen it coming, taken better precautions, but she said she was on the pill, and most people didnt want to use a rubber when fucking her. I sure didnt.

    I think it must have been because she missed a pill one day. That can throw your whole body schedule off and youre not perfectly safe for a whole month after. Or maybe she just got a bad batch, and it was ineffective. They say no form of birth control is 100%. But a home pregnancy test soon confirmed that she was pregnant.

    It was anybodys guess who the father was. Odds are, just by sure volume of cum pumped into her this summer, it was mine, but it could have been a dozen other guys. There was even an outside chance it was Freds dog the pooch had certainly dumped enough spunk in her, while we watched, to breed a whole litter of half-ginger puppy-kids. I know people say cross-breeding like that is impossible, but when youve managed to get your own sister as your willing sex slave, you start to believe anythings possible.

    Even though it wasnt totally my fault, I was pretty vocal about my apologies, sobbing like a baby at first in her lap, until I calmed down and we were able to discuss it. She seemed to be the rational one, but I think she was just still numb from shock. She didnt want to keep it, since she knew it would ruin her life. I told her Id pay for the abortion. Luckily in our state parents dont have to be notified. I took Faith to an abortion clinic, and we got it done. She was a bit broken up afterwards, and in pain after the anesthetic wore off, and we didnt discuss sex, or much of anything, for a few days. I figured she hated me for what Id forced her to go through. I wouldnt have blamed her one bit.

    Finally, I decided I couldnt take the silences, and would rather she told me she hated me if that was what she felt. I went into her room to talk to her. Since I usually only came into her room for one reason, she asked if I wanted to fuck her.

    No, I said. Dont worry about that. Because of what happened, Im releasing you from the rest of the deal. Schoolll be on again pretty soon anyway.

    A bet is a bet, she said firmly. Until school starts up again.

    Then Im not going to order you to do anything until time runs out. Youve already been through enough. I never wanted to hurt you. So the bets over.

    Okay, she said finally. Thank you. We sat there a while, quietly, and then she said, The next time we do this, can we use condoms more often? I dont want to go through that again.

    I was a little stunned. Next time? Were not going to be doing it anymore.

    I liked it though. I dont think we should do it while schools on, but I thought I could be your slave again next summer, she said.

    What? I thought shed wanted the whole slavery thing, but could never be sure if it was actually that she wanted, or if she just went along with that for the sex. She never admitted it so openly before, or given any hint shed want to do it after the summer was over. Next summer, I repeated.

    Only for the slave thing. With school and everything, I just think it could get too crazy. But you can still touch me anytime you want.

    You want to do it again next summer. I was a little slow.

    Maybe over the Christmas break, too, she added as though she was uncertain on that point. But definitely next summer.

    Id be a fool to turn that down, but I had a rare moment where brotherly concern completely outweighed my baser instincts. Lets not go too crazy, okay? A lot can happen in a year. You could get a serious boyfriend. You might regret wed done it all. You could start to hate me. By next summer, you probably wont even want to do it again.

    She grinned at me. Wanna bet?

The End
