Okay I need to get this off my cheast. I was at home alone one evening, my family had gone to the supermarket. I decided to gone onto an online web chat site, looking for a cute girl to talk to. Its a bit weird but used to do this alot before masturbating, i was 15 at the time.
so i went on and almost instantly i met this very hot women and she was strpping for me, as i was for her. I was getting so h**** and then she stopped and asked me 'do you have a sister?', and i do so i said yes (my sis was 13 then). Then the hot lady said she would only continue to strip for me if i got a pair of my sisters knickers for her, as proof i have one.
It was a bit weird but i went to get the knickers for her, after seeing them she she told me to play around with them over my d*** and finaly c** on them, im ashamed to say i did, but that isnt the worst.
After doing this with her knickers i started to notice them alot more round the house, in her draws, on the ironing board and in her dirty washing pile. One day i got back frpm school early and i really wanted a w***, on my way to my bedroom i noticed a pair of my sisters dirty knickers on the landing, i could see they were dirty by a small yellow smear on the inside. This gave me a b**** straight away. I picked up the knockers and ran into my room.
i straight away pulled down my trousers and started wanking with my 13 yr old sisters dirty knickers right up in my face. I was sniffing them very hevily. It took only seconds for me to o******, thinking that this small strip of fabric has been right up my sisters vag. Im asamed to say it was a very good w***, i havent been able to look at my sister in the same way since.
i dont know to do! I cant stop thinking that i orgasimed over the smell of my 13 yd old sis's vag.i still geta bit of a b**** thinking about it now! Horible thing is i have thourght about doing it again. How wrong is this and do i need help????
