Without thinking too much about what I was doing, I dressed in the lingerie. I admired myself in the mirror and suddenly wondered what the hell I was ...oing. Here I was standing in the family house of a guy I had met two hours earlier in a bar, fucked, tied up and verbally abused and now I was trying on his sister’s underwear! I walked out of the bedroom and downstairs to the kitchen, still wearing the borrowed underwear. I was getting really turned on and I was panting a little with excitement. To fill in when she needed, she would fuck her neighbor in the apartment complex where she lived. She had settled down a bit but she was still active. After about two or three months word got around at her work. As it turned out one of her co-workers was the girlfriend of one of my co-workers. So when my buddies decided I needed to get laid, he came up with her. That is how we met (see part 1).So now we were living together and fucking every morning and every night at least once. Sometime. I watched engrossed as her skirt was lifted high and her panties were pulled down to just below her bum, and the guy behind was releasing his cock and pushing it into her naked bum. We both could hear her, she was almost grunting and making all these sex noises, that was when daddy asked me, "Do you know her, shall I go across and intervene"?I heard myself reply, "Best not too Daddy, she might get pissed off", and then I reached for my phone and started to record it. I think my father was. Krystall lifted onto your tiptoes to reduce the vibrations passing through your clit, although you couldn't stand that way for long & had to take breaks, which drove the vibrations through you hard. I stepped up the vibrations & made a gesture with My other hand, signaling to Miranda to add to your torment. You felt hands slide around your middle gently caressing your white skin & breasts, running around to your back & down over your phat ass, a finger occasionally teasing your pink puckered.
