I think that my favorite thing about my mom's new boyfriend Simon is that he likes to make fun bets with my mom -- and MOST especially that, when he wins, he can always get her to follow through with the wager.

It's really nice to see my mom so happy - and fun! I mean, my mom is a real knock-out, and she's always been great and super-sweet and stuff, but before she met Simon on the internet, it was like she was always really tense and never quite enjoyed herself. Then she went on a couple of dates with him, and POW - it's like he's totally let out her wild side, you know?

Every time they come back from a date now, he always fucks her one last time -- doggie-style, right in front of the couch so me and my sisters can watch -- before he leaves ... and they always decide on a new bet. Emmy, Cate and me are supposed to be the witnesses, so nobody welshes on the deal.

Anyway, this last time, my mom was real dumb: she bet Simon that his friend Leroy wouldn't have the balls to fuck any of her daughters, right in front of her at the dinner table, during family Uno night. And when she lost that bet, well ... we ALL had to pay up.

My little sister Cate, by the way, well, her favorite thing about Simon is probably his dick, which she's finally learned to take all the way up her ass. And as for Emmy, my big sister, I think that she mostly likes Simon's dog, Kubla. She likes Kubla a LOT.

But, me, I think that him getting my mom to take us all to parties is the coolest part.

You should have seen her when she lost the bet: this high-powered business woman, there on her knees in the kitchen with those awesome tits hanging out, working double-time with her mouth and both spit-slick hands, trying to get Leroy to cum before he slipped that monster cock into me, with me squirming around on his fingers and begging for him to 'fuck a baby into me '.

It was awesome.

I'm not sure, but I think that if Simon hadn't grabbed Cate, bent her over the table and started fucking her right there in front of us, Leroy might not have had the balls to do it. Part of the rules of the bet, after all, were that nobody was allowed to tell Leroy what was going on ... but we kind of cheated: none of us girls showed up with any panties under our skirts, and Emmy kept missing her turns because she was playing with Kubla's dick -- or bucking around in her chair with half her fist jammed up her cunt while the dog licked her clit raw.

My mom totally lost that bet - I got my little pussy creamed real good that night by Leroy, and took that huge tool all the way to the root before he nutted.

So we got to go to a party!

Specifically, it was a fraternity event -- and Simon told us to dress to impress.

That night, my mom looked like a supermodel, I'm not even kidding. We trimmed her pussy for her, making her bush into this little heart, and she was a total fox in a short, sparkly red dress that Simon bought her - it was like something a twenty-nine year-old Jessica Rabbit would have worn if she wanted everyone to see her cunt better.

Me and my sisters also wore outfits that Simon picked out for us: a blue, bow-tied sailor-girl skirt for Cate, a pink fairy-princess ballerina-tutu for Bree (that's me!), and a tight black biker jacket with a leather skirt for Emmy, since she just turned fifteen and finally has the tits to really make it look good. We stood in the front hallway of our house, each of us trembling and quiet -- and each with a handful of Vaseline, like he told us to have ready -- while Simon inspected each of us in turn.

We were all holding our breath -- after he was satisfied that we looked good enough, he told all of us to turn around and face the wall.

I watched as he flipped my mom's skirt up, slapped her once across the bare ass, and then pulled a thick black magic marker out from his jacket pocket. He hauled his thick cock out, rubbed it across my mother's slippery pussy lips, and fucked her for a few strokes while he told my mom to rub some Vaseline onto the marker. Nodding, her hips rocking in time to the thrusts, she held onto the wall with one hand and used the other to rub the marker like she was massaging a dick. Taking the marker back, Simon pulled out of my mother's sloppy sex with a wet plop, drew a single one-inch black line up and down on my mom's ass-cheek, and then slipped the slick pen up into my mother's tight asshole.

"Just warming you ladies up. Whoever comes home with the most fuck-marks gets a special prize. Think of it as a bet -- so be sure to ask the boys to draw a little line on your pretty white behinds when they're done ramming their cocks into you."

He was now pounding into Emmy with short strokes: her mouth was hanging open and her eyes were closed. She always gets like this when she's about to get gang-banged. She rubbed the slick marker with one hand, kneading at it like she does with Kubla's big pink doggy-shaft.

"Daddy, do butt-fuckings count double?"

I looked over at Cate, who had her shirt tucked up under her armpits and was already playing with her tiny, hairless pussy with both hands, rubbing her Vaseline into herself, her eyes wide. She loves to call Simon 'Daddy' -- seven year-olds are such babies.

He grinned. "Very good question, young lady. The rule is that only fraternity brothers -- yes, Emmy, you little whore, push back, shit yes --- who fuck you get to draw a mark on your little ass, and all fucks are worth exactly one mark -- but you can ask a man to send over three friends at once to fuck you next, if he thinks you did a particularly good job."

Cate beamed her patented shit-eating grin as she reached back with one arm, trying to open up her ass with her other hand. "I will, Daddy."

Simon gave her a warm smile, pulling his over-sized cock out of Emmy's steaming-hot cunt before making a single precise mark just to the right of her tailbone. "You know, one little girl I used to fuck came home from a party like this with marks across both ass cheeks, all the way down both legs, from her hips to her ankles."

"Wow."

"That's right, 'wow'."

Simon flipped the back of my skirt up, slapped my ass, and began rubbing the slick head of his cock through my juicy pink lips. He wrapped one hand around my throat and squeezed, making it hard to breathe, and I felt my wet hole split wide as he sunk into me. I was lifted onto my tip-toes, feeling his throbbing member punching inside of me.

With my face pressed against the wall, he placed a thick black magic marker in my Vaseline-ready hand, and I began getting it as slick as I could.

After only a few seconds, FAR too soon get the cum I needed, Simon's enormous cock pulled out of me. The feeling of his massive member leaving me ... god, I was overheating, wet and tingling, loose and empty -- and a moment later I felt a him draw a little vertical line on my toned butt-cheek. Then hard, slippery plastic began to invade the first six inches of my ass-guts. Christ, that man gives me goosebumps!

Breathing hard, I looked to the side -- Cate had gotten on all fours for her fucking. She grunted and grinded back against Simon, on his knees, letting the little 8-year old push his cock into her.

"Now, you ladies drive safe. Your mother knows which house -- yes, good girl, yes, open up for that cock -- the party it is, and I'll come get all of you in the morning."

"You're ... oh, fuck ... not ... shit fuck ... coming with us, Daddy?"

"No, pumpkin. Daddy has a date tonight, but I'll be there later."

"Are you ... god fuck god ... sure you won't come?"

"Well, maybe I'll stop by. But somehow, I think you'll be coming enough for both of us, baby-slut."

He slipped his dick out of her itty-bitty fuck-hole, made a tiny black mark on her little white cheek, licked the end of the marker, and then screwed the slick plastic into her puckered pink shitter.

"Thank - th-thank you, Daddy."

"You make me proud, my lovelies."

We pulled up, markers still in place, and it was obvious that the party had gotten started without us. A dozen pairs of panties were hanging from various branches in the yard, and loud music was blaring from the giant old building. The fraternity's letters were brightly lit, shining into the yard, and I could see one girl asleep face down, beer still in hand and skirt pushed up around her hips, passed out on the lawn.

"Now, you girls be nice. Say please and thank you."

Emmy piped up, her voice bored like only a teenager's can be: "Got it, mom."

"I mean it. And if someone offers you a beer, it's okay to have one or two, but don't get sick or Simon will get mad."

Cate was almost bubbling over with excitement: "I don't want any beer, mom. I want to get fucked!"

"Alright, that's the spirit."

I couldn't help it. "Thank you for losing that bet to Simon, mom. You're the best!"

"Oh, hush. You and that little potty mouth of yours are what got us into this."

That made me really, really happy.

Mom led us up to the door and knocked. The door opened and a good-looking guy with a beer in his hand in a smoking jacket draped over his shoulders opened the huge door. The music got louder, and I could see the silhouettes of people dancing and drinking inside.

"Hi. I'm the General, and you must be Simon's friend -- Darlene."

I could tell that my mom was nervous. Her voice almost cracked, and she swallowed hard: "Yes. These are my daughters Emmy, Bree and Cate."

"Why, it's very nice to meet all of you; you're even more beautiful than I expected. Well please, pretty ladies, come on in. It's cold out there!"

Cate: "So, uh ... will you fuck my little pussy, mister?"

"Catherine!"

"Oops. I mean, will you PLEASE fuck my little pussy, mister?"

He laughed. "Oh, I think that we're going to have ourselves a lovely time tonight, Darlene. I'm going to introduce your littlest one here to a good friend of mine named KP."

The General put his arm around mom's waist, pulled her close, and started walking around with her like she was his date.

It was really sexy.

Once we were inside the fraternity house, it was like something out of a movie. A really dirty movie, specifically. Like something off of one of Simon's websites.

In the living room, a group of college-age guys and younger girls were sitting on couches, making out, drinking, passing a bong around and watching a gorgeous young girl with big tits and duct-tape over her mouth -- also, binding her wrists together behind her back, to her ankles -- getting fucked by a big Huskie dog. She was squirming and crying with her cheek pressed against the floor, with cum running down her face and caked into her long blond hair; after a moment, I could see that loops of tape were wrapped around her thighs and calves together, too, holding her lower legs into place so that she couldn't get off her knees.

In the corner, a high-end digital camera was running; a tall, athletic-looking guy next to it was idly nursing a beer and manning the recorder while a curly-haired brunette with pigtails bobbed up and down on his cock.

"Darlene, ladies, this is Jerry's little 15-year old fuck-socket sister Amy. Jerry's sister, these nice ladies are going to compete with you to see who can take the most dick tonight. These girls are ready to rock, but I have a feeling that you just might get raped inside out before the evening is through. There are a lot more doggies where this one came from."

I looked over and saw that mom had already pulled the General's cock out and was milking it gently while watching Amy get fucked. He, in turn, had casually pushed her skirt up in the back to toy with her ass, letting his fingers run around the marker poking out.

Emmy just couldn't take her eyes off the thick k-9 cock plunging into the blond, and she walked over to run her hands around the wide shaft as it pumped into the sobbing girl's unwilling hole. She unzipped her jacket, showing bare skin from her neck to her belly-button. "I'll bet that I can take more of that doggy-cock than she can, though, Mister General."

He smiled. "You ... BET? We take that sort of thing very seriously around her -- as I'm sure Simon has told you."

Emmy stared, licking her lips, her hand exploring the violent intersection of inter-species flesh. "I'll bet, yeah. I bet I can take more dog cocks than every girl here put together."

"And what if you can't?"

Emmy turned, her bright green eyes blazing, her pretty features flushing hot. I could see her whole arm moving back and forth as she fucked the dog's cock into the crying blonde's cunt. "Anything. Anything at all. Seriously, fuck, mister, can I be next?"

"Next? Sure, fine by me. If you lose, though, we're getting you pregnant. Tonight, or tomorrow night, or for however long it takes. And once you're pregnant, you stay here in the frat house as our party-favor. How does that sound?"

Wordlessly, my mom dropped to her knees and started deep-throating the General's cock.

Emmy blushed, her hand working the canine's member faster. She was moving her hips rhythmically now, in time with the fucking the huskie was pounding into the horrified blond. "Okay."

The General smiled. "I see you like that idea. Well, then it's a bet. Witnesses?"

Everyone in the room said "AYE" all at once so loud it echoed. It was awesome.

Rocking his cock into my mother's gagging mouth, the General turned serious. "I'll have the house kennel-master bring us some more dogs, then. You -- freshman! Go get a dry erase board and a marker, and write down the names of all our lady-guests; we're going to need a scoreboard. Then mark down Jerry's worthless fuck-toy sister here for six already."

Emmy gulped, her unoccupied hand now stroking at her clit, hidden under her skirt.

The General smiled. "First, though, before this dog nuts in Amy and she moves to #7, in the game-room, I'd love it if all of you lovely young ladies would be so kind as to take a piss on little cunt-meat's face. She's been upset about all the semen on her, I think, and it only seems fair to let her get washed off."

Without hesitation, Cate stepped forward, lifted her dress in the front, and let loose a stream of hot piss, catching Amy in the eye. A laugh went up from the room. As the stream turned to a dribble, a pair of muscular guys effortlessly hoisted her and began walking her up the stairs to the bedrooms. The last I saw of her that night, she was shouting down that she had three holes -- and they needed another guy.

That got another laugh from the room. I really liked this place. I couldn't wait to visit when they got Emmy knocked up.

My mother stood, wiping a steam of saliva and the General's precum from her chin, to begin hiking up her skirt and take her position -- there next to Emmy, who was already pissing on Amy.

After a moment of hesitation, I raised my hand -- feeling embarrassed.

"Yes, Miss Princess?"

I started blushing. "I can only pee in front of strangers if someone sucks it out of me."

"That's no problem, young lady. Whore Jen, you heard the word 'suck' - get over here and earn your privileges."

The skinny brunette popped off of the bobbing dick in front of her with a slurp, and slid across the floor to run her head up the front of my frilly dress and work her thick dick-sucking lips around my clit.

"Wow!"

"Oh, yeah. Little Jen here is worried that we're going to let the dog fuck her, and she's doing everything in her power to just be too damn fun at everything else. Hell, I've had her lick out the inside of my ass while I raped her little sister. This bitch will do just about anything not to get filled with doggy-cock like her pal Amy."

As the curly-haired, pig-tailed little minx leaned in, sucking my fat cunt lips into into her hot mouth and lapping her tongue into my slit trying to get piss out of me, Emmy finished her leak onto the shaking blond. Then she flipped her short leather skirt up and began running her fingers, now wet with dog-fuck and urine, against her slick pussy.

The General crept up, slipped the pen out of my mom's ass, then stood behind her as she opened her knees wide to piss.

He began running his nine-inch cock between her legs, and my mom started breathing heavily. Massaging his huge fuck-meat, rubbing the shiny head as is ran back and forth between her mushy cunt-lips and cooing, she leaned the back of her head against his chest. "Uh, Mister General, sir, I, uhhh, don't know if I'm going to, oooh, be, ahh, able to pee like this, if you, if you, ahh, fuck, start fucking me."

"You don't get fucked until you piss on this bitch. I just like to feel it dribble off my cock."

That did it for me. Well, that and the little tongue playing at my piss-hole. Jen started sputtering as I filled her mouth with warm pee, which she spat into her friend Amy's face just as my mom's stream hit her.

All of that got another laugh from the crowd.

Emmy wound up pregnant that night anyway, as did Mom, but she totally won the bet.

Yep. It turns out I really do like fraternity parties.
