As I went upstairs to go to my room I heard my 14 year old sister Jennifer talking to somebody so I walked very quiet to her room and listened. She wa... there with her best friend Ashley they were talking about boys and sex Jennifer was saying she couldn't wait to feel a hard cock shooting its stuff in her pussy. Ashley said, you want to feel sperm shooting into your belly. Jennifer said, yes I want to see what it feels like. Ashley said, you could get pregnant if you let a boy shoot his cum in. I actually did not feel shy but to avoid that i asked her if she has danced to that particular tune which was playing, anytime with her husband. Asking that question i felt that its wrong on my part and i was trying to avoid the discussion. Around 12 the rain stopped for a while but the breeze was continuous and its making us feel cold.she asked me to latch the door and she went inside the bathroom, may be for a pee. When she came out i could see that she has already removed her brassier and. Time and again they did it and even told me they were not going to let me up but tie me up in the middle of the store naked and leave me there when they left. I think they were surprised when I said in a very very hot voice, Oh, yes, please do, tie me up and leave me till morning so they will find me naked. The teasing continued and then the short haired one stooped over my face, Oh I have to piss so bad. she said and a stream of piss sprayed over my face and I opened my mouth wide to take it. I could get my dick in there without maneuvering it in, right? Out of all the things I could do I really hoped I wouldn't be the asshole that needed to grab his dick and actually attempt to position it into a pussy. I felt my cock slowly make its way in as her body tensed under me. She yelped slightly as I began to thrust in and out of her. I could feel the sweat dripping down the back of my neck and the pressure building up in my balls. No no no, I wasn't a 16-year-old boy. I have to at least.
