Mary was really hot and she had a thing for me. She once confessed she found me attractive, she was a minor back then so i refused. But she had recent...ly turned 18. She had also gotten more sexy. One day when Jay was out with friends, i was masterbating in my room, i had left the door open so she could see me when she came to call me. She did and to my surprise he barged right inside. I was laying on my bed with my 7 inch hard cock. She came inside my room, locked it. She asked if she could help. Stood there waiting. I was afraid and excited, both at the same time. What if I'd guessed wrong? It was possible that I was kidding myself here. Was this like an ant trying to rape an elephant? Every second that I waited seemed so much longer than that to me. By the time that I'd begun to be convinced that I had been right, and the voice would have to deal with me on a more equal footing, I started sensing that I was all alone again. I couldn't feel his presence with me at all. Silence. I couldn’t help it if my bum made my skirt that bit shorter. Was it my fault that my shirt didn’t quite fit because my boobs had exploded since my Mum paid for it? Now though, being 18, I was different. I didn’t have a uniform anymore but I could dress just as teasingly – if not more so. Whereas the uniform had guidelines – sort of, at college you could wear what you liked. Well almost. When I dressed for college on that late spring morning, with the sun bleaching my curtains, I thought solely. “Stop!” she shouted. “Stop!” This was something else that was new for me. None of my previous lovers had ever cried for me to stop. I hoped I hadn’t hurt her. “I need to rest for a moment.” She said, again apologetically.“Are you okay?” I asked, concerned that I had done something she didn’t like.“I’m fine, it’s just… well it was all too much for me. I have never felt quite so… I don’t know.” I thought that her reticence in saying the words that described her getting close to orgasm was perhaps.
