The plot thickens. One night my girlfriend Karen told me that she let her brother Peter fuck her brains out. The day after she told me that he filled her tight cunt twice. That was supposed to be the end of their little affair. However, apparently their sister Jeanine saw them fucking around and now she wants Karen to do something for her so she won't spill the beans to their parents and me.
"What did she want you to do?" I asked her while she was lying against me on the couch. Karen still wore her top, but other than that she was naked from the waist down.
Karen started to tell me how Jeanine played her carts.
Karen was taking a bath, soaking her nicely shaped body in hot water. Jeanine walked in the bathroom. She did not bother knocking.
"Hey, what the fuck are you doing? I am having my bath!" Karen yelled irritated.
"Yeah, so what? I've got to talk to you, little sister."
Jeanine gave her a stern look. Meanwhile she looked her sister over. She hated her sister's slim body and beautiful breasts. Now, Jeanine wasn't ugly or anything, but not a looker either. Her ass was a bit plump and her big tits did sag a little bit. But on the positive side, those breasts were impressive and she had great full lips that would make any cock happy. Still, Karen seemed to come home with all the cute boys, while Jeanine... well actually we didn't know a lot about her at that point. She never brought anyone home, so we assumed so was sort of a wallflower. But who knows whom she was fucking outside of the house.
"You know Raymond, right?" Jeanine asked.
Karen wasn't interested. "Who?"
"Raymond, the guy I work for at the bookstore."
"The big black guy?"
Jeanine nodded. She walked behind Karen and squatted down on the ground. Jeanine put her hands on Karen's shoulder.
"What about him?" Karen asked. Feeling a bit uncomfortable by her sister's hands on her body.
Jeanine came close to Karen and whispered: "Raymond has always found you very attractive. The other day he told me he really likes to fuck you."
Karen replied: "So what? I've got a boyfriend remember?"
"Really? That didn't stop you from fucking Peter a while ago..." She whispered in Karen's ear.
Karen began to sweat. So Jeanine did see the whole thing. "I-I don't know what the hell your talking about."
Jeanine grabbed Karen's shoulders tight. "Don't play with me little sister. I saw you guys screwing each other. He even took photo's of your soaking cunt."
"You can't proof that."
"Can't I? What would Robert say if I told him what you did? What would dad say? Peter is not the only one with a digital camera you know," Jeanine said.
Karen knew she was in trouble. "What do you want?"
Jeanine let go of Karen's shoulders, and put her hands into the hot water. She let her hands creep down Karen's body until she reached her breasts. Jeanine took hold of Karen's nipples.
"You've got two options. One, you'll let Raymond fuck you in every hole he desires."
She paused for a moment, tightening her grip on Karen's nipples – making them hard. It left Karen almost breathless. "Second choice might be slightly better..."
"What is it? Stop twitching my nipples..."
Jeanine did quite the opposite and pinched a little harder. It hurt Karen, but she got horny despite the situation she was in.
"Second option is, I get to fuck Robert. I want his fucking dick in my slit pumping away, like Peter did yours." Karen was silent for a moment. That fucking bitch saw everything they did and now she wanted to do her boyfriend. "Well, although Robert always said you needed a good fuck to loosen you up a bit, I really doubt he was thinking of himself as the one to do it. I think you can forget about that, aaahh..." Jeanine was turning Karen's nipples even harder. Karen didn't want to admit it, but she liked every second of it.
"Listen baby sister. You've got a week to work this out. You either let yourself be fucked by Raymond – boy I'd love to see that big black cock of his impale your skinny white pussy. Or your boyfriend is going to give me a lot of pleasure. How you make him do that, I don't care. Just do it."
Jeanine let go of Karen's nipples. She dropped one hand deeper and quickly inserted two fingers in Karen's pussy. "Oh, and one more thing. If you let Robert fuck me, I want you present when it happens. I want you to see your boyfriend fucking me. You fucking horny bitch," she said. Karen decided not to stop Jeanine and let her touch her most private area since she didn't want to cross her sister anymore. Besides, once upon a time, when Jeanine and Karen were much closer, they had felt each other up lots of times discovering their sexuality. (But that's another story.) Jeanine pumped Karen's slit three times, and touched her engorged clit when she retracted from her wet pussy. Karen's legs shuddered. She was on the brink of cumming. Then Jeanine stood up and walked out of the bathroom. "One week, Karen. One week."
When the door closed, Karen let out a deep breath. She put her left hand on her clit, rubbed it and came instantly. "Oooohhhhhhhh..."
I couldn't believe my ears when Karen had told me that. I was so stunned, that I hadn't touched her body during the whole story.
After being silent for I while I said: "That little bitch. She got us by the balls."
"Yes, I guess she does," Karen replied.
"Have you spoken to Peter about it."
Karen shook her head. "Nope. I decided to tell you first, to tell you everything so she couldn't blackmail me anymore."
"Well, she can still tell your parents. Or show the pictures if she indeed made photo's that night."
Karen sighed. "I guess so. So what are we going to do?"
"Well, I don't know about you, but I don't fancy you being fucked by that Raymond. Don't like that one bit."
"Neither do I, honey. I don't like the bastard. He is always looking me over, with those horny beady eyes of his. I'd rather die before I let his cock penetrate me."
I kissed her forehead. "So, that leaves us with option two, doesn't it?"
Karen looked me in the eye; she had a surprised look on her face. "Don't tell me you're seriously considering giving Jeanine what she wants. Y-you don't want to fuck her, do you?"
