I go over to the bed and then look around and you are nowhere to be seen, I decide to get a quick shower to warm up and then get changed. Im in the sh...ower getting warmed up when the light goes out, then shower curtain moves and I feel someone grab me from behind. I start to scream and feel something pushed into my mouth, pushed up against the wall and my legs spread open. Whispered into my ear I hear, don’t struggle, relax and enjoy it.Your hands start to explore my body, I still can’t see you. I felt that Malcolm had had a good long look at it on the way out. Later this would happen time and time again but it never inhibited Collette at all.After he had left Collette just carried on as if nothing had happened. I found that I was even more turned on than normal. Collette just kept getting dirtier and dirtier that morning and that was the first time I tried anal sex. Collette had said that we could try it on her 18th birthday but she just offered me her arse that Saturday morning. She was actually a few minutes early at Tony's. She greeted me with another hug and a heartfelt, "Oh, Gerry, I'm so sorry..." Dad warned me," I responded, "that hard science is a demanding mistress. I really don't mind sharing you, Emma, but I'm going to demand my share of your attention."She looked a bit worried at that, but I went on, "Love, I know you're going to get immersed in whatever train of thought you're following and most of the time that'll be fine. Just try to remember you don't. I could feel him trying to find my soft spot, pushing between my cheeks. He was urging me to relax and let him in, his hard cock stabbing at my arse. I felt the pressure on my hole as he tried to push inside, yelping out as he thrusted against me. He told me to ‘Shhhhh’ and brought his hand round covering my mouth. I could feel his other hand trying to pull my bum cheeks apart and I cried out again when I felt him penetrate me, the head of his cock inching past my tight ring. His hand clenched.
