“Why?” I began but stopped as the leather strap flicked across my thigh.Suzie’s eyes were wide open as she watched me get into position, everyth...ing was on show.Mike stood at the end of the table, his cock hovering over the top. He pulled me towards him until his cock was just pushing into my slit, then he stepped back and picked up the strap.“I am going to use this strap on your cunt, just like you used it on my penis. Don’t move or try to stop me or else.”He smiled as he flicked the strap. I used to watch her cooking over her shoulder watching her sweaty cleavage. Sometimes I used to rest my hands on her shoulders and smelled her neck. It was such a wonderful feeling and slowly my mind moved away from mother sentiment to a sexy hot female.She never minded while I moved around her and we also watched TV while holding hands together which itself gave me full erection multiple times. I was feeling jealous on my brother and tried to listens their bedroom sounds at night but I. I pumped it in and out and then I took it out and slipped it in my mouth and sucked the juices off. I quickly returned to fucking you but this time I slipped two fingers in. You began to moan so loud that everyone in the theatre could hear.Suddenly, a man appeared in the row before us and gazed down. "My friends want to know if we can all watch." He said. You smiled and looked up to him and nodded approvingly. He motioned to some other people and soon the man and three of his friends surrounded. I cant count the number of times that I have looked through my bedroom window to see these two naked women flat on their backs with their legs open, pointing their pussy at my bedroom window, I sometimes wondered if they did it on purpose.It had been just the three of us since my Dad passed away some years ago.So Friday came around and after initial card and present opening, my sister, became more and more withdrawn. I was quite worried about her, so I suggested to Mum that we start the party.
