"No ma'am" I panted, trying to calm my now raging erection. "Ma'am? I like the sound of that." Michelle giggled, taking the razor to my balls. "Anythi...ng you say ma'am." I breathed. "Good. Now keep still." It didn't take too long for her to be washing the last of the soap from my now hairless dick. "What next?" I asked. She looked up sternly. "Sorry. What next ma'am?" "Well, you know I've always wanted a little sister to dress up..." She tailed off, the smirk on her face once more. "NO!" I was. She was really getting into one night when we were fucking she kept yelling for Al to fuck her harder.Finally about two months later I got the nerve to make it really happen. On the night that she fucked him, I told Al to wait outside until I came to get him. I tied Sandy to the bed all naked and spread eagled, she didn’t know it, on this night I set up the movie camera to capture the festivities.I snuck out momentarily and let Al into the house. He undressed as I started to massage Sandy all. He greeted me with the same kiss as his son. I walked behind the car with garage door still open he pulled down my panties and my pants down in one downwards motion. Then he inserted his cock in to my wet vaginal opening and he went in deep repeatedly that the car moved. It was so funny that we could fuck so openly and no one walked in I just closed my eyes when we came together and thats when I got just and evil ideal and I could not ignore it. I invited their whole family over to my house. He used to invite me up to his bedroom , well one day he had a naughty magazine and he asked me if I wanked I said yes well he got his cock out and started to wank so I did as well but during it I put my hand on his cock and started to wank him he was shocked so I stopped , then he asked me to do it again so I did and I tossed him off ,.He shot his load all over my hand so I said I off to wash my hands , little did he know that I was going into.
