At first I was disgusted at my sister, but then I remebered the feelin of her hands rapped around me, and the feeling of her tits on my arm and I star...ed to relieve myself and came everywhere. That was the first sexual experience I had ever had, and also when my attraction started for my sister. the next morning she woke up and had no recilection of what happened! so I thought i'd best not say to her. A few months on we had guests staying in our house and I was made to sleep in my sisters room. The routine is always the same, I come in, get undressed lie on his bed, he fucks about with his phone and monitor in search for porn and then we settle down to playtime. I take his flaccid penis into my mouth and work it up to an erect monster of a cock and then he does the same to me, usually I fail to perform and so he lubricates my ass, his penis and slips his whole 11inches deep inside me, each thrust harder and faster until he explodes and deposits his seed directly inside me. Sometimes. It was so humiliating to be bent over the doctors lap, presenting my anus for her fingers, but my puss was enjoying it.Her fingers pushed into my opening as I gasped."Very good, you naughty girl, opening yourself up like that. Keep alternating between bearing down and sucking in"Her fingers wiggled around inside my bottom as I did as I was told. I could feel my asshole suck her fingers deep inside me, then push them out again, when suddenly, I felt the suppository start to work!It was stinging. Unfortunately, as I kissed along the line of your pubic hair breathing in the scent of your sex, you realised my intention, and for whatever reason surged through your mind, you stopped me and pulled me back up.Not put off, my fingers continued pleasing you, alternating between finger-fucking and teasing your clit. I was aware your breathing was quickening, the moans increasing until finally, you whispered, “You make me want to.”‘Want to? What to what?’ I thought. You must mean you want to do.
