" I shivered at the obscenity of what I was saying. I know it's wrong to let my son ejaculate his sperm in his little sister ... especially consider...ng that the younger girl has been having periods for over four months now; and had finally finished her first regular flow a little over a week earlier. Somehow the danger of having my barely teenaged boy actually impregnate his eleven year old little sister with his incestuous sperm just increased the thrill of watching the two kids mating. We enter the house there are still hands fondling my ass and tits as we go into a large lounge, very neat and tidy for, four guys living together. Robbie who is West Indian gets everyone a drink, music is put on, I feel fantastic, surrounded by four horny studs. The guys are all around me they pull my dress over my head, I am now just in my heels and lacy thong, I am lowered down onto the rug I can feel lips on my nipples gently biting, nipping deliciously, a hand is rubbing. "I can entertain myself."All right," she said. "I'll take a nice long shower and get myself all relaxed so we can have a good time going out tonight." She smiled at me one last time and walked through the door; I caught a final glimpse of her beautiful naked body as she shut it halfway.I rolled my eyes; I couldn't believe how much she was turning me on! Here I was in this gorgeous woman's apartment and she was naked in the other room! It'd been months since I'd picked up a woman; I'd been. I always imagined watching a guy go in and I’d follow him and end up on my knees sucking his cock but I could never build up the courage to do it. Anyway I was sitting there minding my own business when a white car pulled up on the other side of the road from me. It was quite a warm night so I had my window open but my music turned down so as not to draw attention to myself and the next thing I hear is this quiet voice calling over saying hi. I turned my music down to hear him better and called.
