I never expected what I saw. Instead of visiting my sister and seeing her interacting with her children she was no where to be seen. Her two kids were sitting in the living room watching television. Their toys were strewn about, as if their mother, my sister had ignored them for some time. "Where is your mom," I asked openly to both of them?

"She is in her room," said her oldest son.

"Have you two had lunch," I asked?

"No, mom said she would feed us after she was done."

"Done with what?"

"Uncle Joe came over today."

What the fuck? Uncle Joe? There is no one named Joe on my side of the family. Dave, her husband, wasn't related to anyone named Joe. "Okay," I told her kids, "I'll go get your mom and get some lunch for you."

"Okay," my nephew said right before being sucked into the television once again.

I walked to the door of my sister's room and pushed it open a little while knocking lightly, "Karen, you around?"

A sudden rush around the room was followed by Karen covering up under her blankets. A man jumped from the bed and quickly put on his pants and shirt, grabbing the rest of his clothes as he ran off. In a stark contrast Karen stayed firmly in her bed. "Get the fuck out of here," she yelled.

"Why are you fucking around with other guys," I asked. "Dave deserves better than this."

"Get the fuck out of here and stay out of my business. Dave knows about this."

"You are telling me that Dave knows your fucking a guy with a small dick?"

"Its none of your business. NOW GET OUT!"

I reached into my pocket and pulled out my cell phone. "Who the fuck are you calling," Karen asked commandingly?

"Just going to talk to Dave for a second. If he knows what you are up to then I'll leave you alone and let you get back to fucking small dicked guys. Otherwise I'll tell him what is happening."

Karen was suddenly not concerned about her nudity. She jumped out of her bed and ran towards me, grabbing for my phone. I turned by body to keep my phone away from her. I secured it in my pocket before turning back around to confront her. She kept grabbing for my phone, with her hair flailing about and her tits flopping around. Finally, I had enough. I grabbed her little body by the sides of her stomach and threw her back onto the bed. She bounced once and landed against the headboard with a loud thud.

At first Karen didn't move at all. My anger and disappointment turned to worry. I was so fucking scared that I had seriously hurt her. When I heard her beginning to sob my worry became compassion. "Don't call Dave," she said beneath her sobs. "If he finds out I did this again he will leave me for sure."

"You have done this to him before," I asked? In response was only more crying. I took a seat on her bed and rubbed her back trying to comfort her. "I can't let you do this to him. I may not actually be related to him but he is one hell of a guy. And from what I can tell he is an awesome father."

Karen suddenly sprang to life, "Don't call him, please. I'll do whatever you want." She leaned in and kissed me, nearly tackling me to her mattress. She got up and straddled my lap, continuing her bombardment of kisses across my neck and face.

"Karen," I said. She ignored me. "Karen, stop." She ignored me again. "Karen, I can't fuck you, and I can't ignore what you did."

She began crying again and put her head on my shoulder. My own sister was naked on my lap, throwing her body at me, all for the sake of trying to get me to keep my mouth shut. It would be incest, it could be hot. Honestly, I had thought about Karen before. My own wife had even indulged with me in incest roleplay fantasies. I couldn't just do it, I had to think it through. After all I had my own marriage to consider as well.

"Go make your kids lunch," I told her, "I'll wait here and when you come back we can talk about this more."

Karen wiped the tears from her eyes and stood up. She put on a skimpy house robe and left the room. I was alone to consider my options but I couldn't do it alone. I pulled out my phone and called my own wife Jessica. I told her about everything I had seen. I told her about my sister's cheating and how she offered herself to me so I wouldn't tell Dave.

"Are you going to fuck her," Jessica asked?

"I don't know," I said.

"It is the fantasy we have both thought about. You have had a vasectomy so you can't get her pregnant. You can if you would like, I am fine with that. But if you choose not to fuck her then I would understand that too."

I could hardly believe how understanding my wife was about the situation. I would love it even more if my own wife was there cheering me on. "Should I tell Dave about it," I asked her?

"From the sound of the situation you should just help her stay satisfied while Dave is out of town. I don't know if I would tell him though."

"Thanks for your help hun," I said.

"No problem baby. I'm going to come over and pick up Karen's kids. If you choose to have sex with her I don't want them knowing what is going on. Best keep it quiet for now."

"Sounds good Jess. I'll see you in a little bit."

I waited for both women; Jess, my wife, and Karen, my sister. Karen had no clue that Jess was on her way and I sure as hell wasn't going to say anything to her. I had some time to ponder whether or not to tell Dave, Karen's husband, about her cheating. Not only about her cheating but now she wanted to fuck me in order to keep me quiet. I just wasn't that comfortable fucking another woman without permission from all parties that would be influenced by such a coupling.

Karen finally returned to her room. She looked much more composed and confident. Like myself, she also had time to consider her earlier offer.

"Welcome back," I said.

Instead of responding to me Karen simply removed her skimpy robe she had put on before and lay down on her bed. "Lets do this," she said.

"I haven't agreed to fucking you. I haven't agreed to anything. For all you know I could have called Dave while you were making lunch for your kids. For all you know I could fuck you even though I called him."

"Either way I'm going to end up getting fucked. Either my marriage is over or my brother's dick is satisfied. If you are right then it might be both."

"I'm not going to fuck you just so I won't tell Dave anything."

"So you didn't call him?"

"No, but I would like to work some things out first. And if you don't agree then I'll call your husband."

"The only thing you need to work out is your dick. Then you can work it into me."

"Did you actually fuck that guy?"

"Joe? No, he was starting to put on a condom when you came in."

"Where did you meet him?"

"Craigslist," she said bluntly.

"Have you met him before," I asked?

"No, this was the first time. I just get so horny when Dave needs to go out of town for work."

"I can understand that," I attested, "and being horny is what I want to help you with."

"Well then get to it," she said.

"I don't want to fuck you only once. I want you to come to my house whenever Dave is out of town. Between Jessica and I we can help keep you sexually satisfied."

"Jessica knows about this," Karen asked?

Just on time, as if it was fucking scripted, Jessica arrived. Without a knock at the door she came walking into Karen's room and looked at both of us. Karen didn't try to cover herself up as much as she did with me. Instead she only put her arm over her tits and one hand down over her cunt.

"You haven't started fucking her yet," Jessica asked?

I shook my head no.

"Well, are you going to?"

I could only shrug my shoulders.

"Well, Karen, I'll take your kids out somewhere fun. You two decide what you are going to do and call me when you are done."

Jess then walked over and kissed me. "I love you baby," she said.

"I love you too. Have a good time," I told her.

"You too," she said as she left the room.

The room was silent for a bit. I looked over at Karen, she had moved her hands from her tits and crotch. "I can't believe you told her," she said.

"I love my wife," I said, "and I would never fuck another woman unless she said I could."

"And she is okay with you fucking your own sister?"

"Very much so. We pretend to be brother and sister during sex all the time. She really loves that sort of thing."

"Holy fuck," Karen said astonished, "just when I thought I had heard it all."

"I'll fuck you," I said, "but only with the understanding that from now on you don't get men off Craigslist. From now on you just come over to our house when you are horny. I'll fuck you whenever you want and if I am not around Jess will eat your cunt for you."

"I'm really not into women," Karen said, "but that is a good idea. I'll do it but I'll just stick to fucking you."

"That is fine," I said, "but you can't tell my wife to leave if she wants to watch."

"Fine. I'll agree to all of that if you don't tell Dave."

I stood up and Karen understood my prompt. She rolled over towards me and loosed my pants. She pulled my dick out and began sucking. She started slow, just gentle sucking followed with licking my rod and kissing my dick head. She would move her lips up and down my shaft in a fucking motion while holding my dick up to her lips with one hand. My sister then kissed her way down my cock to my balls. She sucked in one and then other. She sucked on both of them for a while before stopping in order to stand up next to me.

She leaned in and kissed me, the taste of my own dick on her lips. Her hands got to work, removing my shirt and pulling my pants down while she continued to kiss me. She pushed me to her bed and pulled my pants off completely. Then she got back to my cock. She kissed up and down my shaft as she had before. She sucked on my balls as she had also done before. Then she moved further down, licking my taint, her tongue teasingly close to my asshole.

Karen licked her way up my shaft to my dick head. She continued sucking my cock in and out of her lips. She finally began kissing her way up my body, grazing on my nipples on the way. "Did you enjoy that big brother," she asked?

"You sure are a great dick sucker," I replied. "Where did you learn how to do that?"

"I read books about it," she said, "then I practiced a lot on Dave."

"Sounds like you are a pretty good wife, too bad you cheat on him."

"I wish he was here more often," Karen said. "Then I wouldn't have to cheat on him. I wouldn't have to have my own brother fill me up. Why don't you put your dick in me big brother?"

"Do you plan on calling me big brother all night?"

"Yes, I think it is hot. Besides, knowing that Jess wants you to fuck me makes it even hotter." Karen straddled me, rubbing her cunt on my shaft. "What do you say big brother? Ready to fuck my pussy?"

I grabbed my sister's hips and rolled her over. I took my place on top of her and began kissing her lips. "No, I'm not ready to start fucking your pussy."

"Oh, come on big brother. You know I need it!"

I began kissing down her body. I paused at her chest and took her breasts into my mouth. Her erect nipples excreted the residue of a mother's milk. It hadn't been long since she stopped breastfeeding and her milk was barely holding on. I encouraged Karen's sweet taste to fill my mouth through suckling her tits. My sister's moans confirmed that I was beginning to sexually pleasure her.

After having my fill of Karen's milk drizzle, I continued my way down. "Oh big brother," she moaned. "please get up here and fuck me."

I continued to kiss my way down to her cunt, "Not after I have a taste of your pussy," I replied. I licked her slit starting at the bottom and finishing with flicking her clit back and forth. I moved back downward, plunging my tongue in and out of her pussy hole. My sister moaned in delight with each of my actions. I sucked her inner labia into my mouth and ran my tongue between them. I sucked her labia in and out, then she began bucking her hips into my face. I continued sucking until she finally let out a loud moan. An orgasm had ravaged her body, letting every muscle twitch with delight.

"Oh big brother," Karen said, "You sure know how to eat pussy."

"Yes," I said, "I love Jessica and she loves pussy eating." I then moved back up on top of her and kissed her lips.

"You taste like my pussy," she said.

I placed my dick head at her fuck hole, "That's okay sweetie. You have a good taste."

I plunged my cock into my sister, her scream of ecstasy confirmed her desire for me. I pulled my dick back out and pushed it back in. I started fucking, slowly. "Oh shit big brother," Karen yelled, "I need your cum."

With her request for my man juice I felt I had no other choice than to begin banging her pussy with all my might. The force of my body slammed against hers with a slight slapping sound. Over and over came the sound of slapping, the sound of moaning, and the sound of my cock plowing through my sister's wet cunt.

Karen began to moan, "Cum in me! Please put your cum inside me!"

I continued pounding her wet cunt while I replied, "You want incest babies with me?"

"Oh yes," she exclaimed! "I'll have incest babies. Just give me your cum!"

"You will get my sperm really soon," I said.

Karen then began bucking her hips up against me much faster and harder than before. The thought of fucking my actual sister had caused my dick to become more sensitive than normal. However, I was able to hold off. I was able to stick it to her until she wildly squirmed underneath me. Her muscles twitched as they had before. Her pussy creamed my dick with an unparalleled wetness. I was able to keep my dick under control until her orgasm slowed. Then I let loose, my manliness filling her woumb one spurt of cum at a time.

"Holy shit," Karen said, "that was just what I needed. Thank you."

"Don't worry about it," I said. "Jess was okay with it and you needed it. Besides my dick can always use a good fucking, even if it is from my own sister."

"I'll fuck you anytime you want," she said.

"Then why don't you come stay the night with me and Jess? Dave will be out of town for a few more nights so it won't matter to him much. By the time you leave I guarantee your cunt will need a break."

"How could I refuse an offer like that?"

Just then Jess walked back into the room. I was still laying on my sister, my dick was softening enough to start slipping out of her. We both looked over at the alarm clock on the night stand. The time had nearly gotten away from us.

My wife sat down on the bed next to us. "Was the sex as good as it smells," she asked?

"Very good," I said. "How would you feel if Karen spent the night at our house for a few days?"

"That may be a good idea," Jess replied. "But it looks like your sister has some cum leaking out of her cunt that belongs to me. Why don't you go get the kids ready to go and I'll see if I can get that cum back."

Karen broke into our conversation, "I don't really want..."

My wife cut her off, "You fucked my husband and now I want his cum back. All his cum belongs to me." Jess started taking off her clothes as quickly as I had ever seen. "Besides," she continued, "It will make it feel good for your cunt to give it to me."

I dressed while I watched my wife start kissing up my sister's legs. Jess stopped short of her cunt, "Go get the kids ready. We should be finished in about thirty minutes or so."

I left the room, closing the door behind me. It was going to be a long night and I was looking forward to it.
