Yvonne's long, lithe form draped off the edge of the bed, obviously more unconscious than asleep from the state of her, and then the smell hit her. St...le wine and sex mingled in the air, and she slumped back against the pillow with tears in her eyes, trying to remember what she could of the previous night.She remembered getting her second glass, and commenting at the time that she couldn't remember finishing the first. She remembered the lights being dimmed, and Yvonne's long, slim fingers. ..nudging my head down to the massive thing I sucked gently on the head to listen to my lover moan a little bit. I got it nice and sloppy wet and was realizing for the first time just how fucking huge his cock was. Well over eight inches and at least four to five inches in girth, it was a huge cock and my pusst hadnt seen any action in a long time. I was only nervous about being stretched. I didn't care about the possible pain or the fact he would bottom out and nudge my cervix but I just. I put on headphones so it would look like I did not hear her come in, but the sound was all the way down. I started stroking my cock slowly in my panties, waiting. I was so nervous I was shaking. I though, I can change clothes right now, there is still time before she gets here. But no, I was going though with it. I was not going to chicken out again.Five minutes went by and I heard the apartment door open, no going back now. I was committed. I heard keys hit the counter in the kitchen. I knew. Than, acting foolish, i stuck my index finger as far into her as she would let me before moanining and turning over. Some nigbts i even put my dick on her feet and gave myself a foot job. It felt so wrong and right at the same time. When she was awake on day i took a risk and put my hand near her ass while she was bending over. I wanted to grab it so badly. I did get caught however, and my relationship with m ly sister will never be the same. Even after i got caught i always umagined fucking.
