Walking around with these two gorgeous girls in the past two hours has started to cause a stiffening in my pants. The thought of fucking my sister in ... public place added with the nature of the taboo sex we have, made the thought of the experience so much better. I decided to go ahead and fuck my sister but I needed to separate her from her friend. So, while they were inside a store looking through stuff I went to the bathroom in the back. Took out my phone and texted my sister.Mike: Don’t say. I had really fallen with my bum in the butter this time!"Don't forget, Sunday is V-Day!" she said as we went arm-in-arm to the bathroom, alluding to the day she had decided would mark the end of her virginal status, with me the designated deflowerer."Won't forget, looking forward to it," I lied. This was an important event in a young woman's life and as I had no experience of maidens I feared I would botch the job and turn her off sex for life. Still, I was flattered to be chosen and would do. Anyway, I got on top of her and she took my dick and led it to her pussy. Everything was all wet down there from her cum and my b*****rs too but I didn’t mind. It felt so good and I slid all the way into her. I went at it the same way I saw my b*****r do it, but this time it was me doing it and I was looking right down at her huge tits bouncing as I fucked her. She started rubbing my back and my ass and I actually lasted almost a minute before I felt that familiar feeling just before you cum.. Weeks and weeks passed. We started to exchange pictures every once in a while. Nothing sexy. Just normal photos. And I started to want her really bad. One night we were talking on the phone and I dropped it."Hey babe," I said."Mmmm," she replied in her usual sensual voice."I can't stop looking at the photo you sent me yesterday," I admitted, referring to a photo she sent me the other day. It was photo of her in front of a mirror, right out of a bath, in her towel. It was the first photo she.
