So, I moved in with no small amount of trepidation...only to fund myself living next to the kindest girl I have ever met. And possibly the sexiest. Mo...e on the latter later.Anyhow, after moving in and working at the library all summer, I got to be a bit bored. I'd never lived alone for more than a week (housesitting for my parents), and I didn't realize how much time it gave me. I read a lot, but even that began to get stale, and frankly, I needed a new glasses prescription.That's when the. “I guess she’s a slut” I said smiling at him.”slut, il show you slut” he said as he grabbed me pushing me over the bed, taking my bottoms off with my knickers almost tearing them. “I’m gonna fuck you like a whore” he said, pushing roughly into me. He really did mean it as well because he fucked me like he was banging in a nail with the dick. It actually hurt a bit and I looked back to let him know but he just kept on till I begged him to stop. “That’s too rough” I said as Debra came walking in. The closer I got the more turned on I became. I could feel the lust building in my balls.I made up my mind that if my brother would not or could not satisfy her I could damn sure do it! Besides, if nothing else I had to at least touch that ass even if SIL got pissed off at me. I carefully sat on the edge of the couch. I could not believe how wonderful she smelt. Timidly I placed my hand on her thigh and got an instant charge of sexual energy as the skin was smooth as satin. I moved my hand. Mary started to move up and down and soon she felt him have a climax. Mary said that he had again made a big load of cum, except this time he had put it deep into her. Mary said that feeling his young cock enter her vagina for the first time was an incredibly thrilling feeling and they agreed to continue to meet weekly and have sex every time. Hearing Mary tell me how Paul had put all that cum into her pussy (he wasn't using rubbers) got me very excited. I was also very surprised how.
