Had dinner with my sister and her daughter Amy (my nice) she is a stunning young thing, just hope she go's lesbian some time and knock’s on my door,...after that we went shopping and ended up in Ann Summer’s, were we tried on a few outfit’s and I got a nice look at Amy’s 16 year old tit’s, (got my pussy dripping. hehe) after buying a nice nurse outfit for the week-end I went home, I found out why my David had not left me any cum this morning, he had a girl round, he must have been saving it all. Then she took her hands and grabs my dick and started her thing, she started jerking my long shaft and playing with my balls and then she licks my tip and started sucking on it. I get excited and moan a bit. Then she goes further and further down my shaft and as she deep throats my cock and licks around my shaft with her tongue, I can now feel my cock throbbing in her mouth and she knows I’m about to cum so she takes it out and bends over on the couch and says “ fuck my dirty whore ass cus. I put my cum in her mouth and forced her to drink it. I then ran outside and waited a few minutes. I came inside our house and saw her sleeping again I put her clothes and removed the blindfold. Morning came and I asked her how was her sleep with the pill. She told it was ok . She asked me where was I last night. I got nervous because she might have remembered what happened. I told her that I was in the house all night. She then asked if heard her asking for my help. I answered no and told her. I wanted to be fucked.Suddenly I could feel it push into me, penetrating me, stretching me, moving deeper and deeper inside me. I gritted my teeth in pain as it entered deep into my bent over virgin ass. I could feel the man behind me put his hand on my hips and start to thrust slowly into my ass. I groaned in pain, but also pleasure. I was bent over, tied up and at the mercy of a man fucking my ass. The thought turned me on as I felt him thrust inside me."Fuck me!" I said through gritted teeth.
