A year later, when Marcy became eighteen, she moved in with me. To any casual observer, we were just another young couple living together. I wanted ...t that way. Although the sex was good, make that great, I still had certain guilt feelings in the back of my mind about living with my step-sister. None of our family knew, which is one of the reasons we did not move out of the house at the same time.Marcy continued her wild ways, perhaps even more so. It was not uncommon for her to invite. Fully naked you slip a towel around your waist and head straight for the shower, with mum and dad at work you don't care much for modesty, you've always been close with your sister and you know she wouldn't think much of catching you in a towel.As you arrive at the bathroom door though you find it locked, the soft patter of water lets you know Brittany is currently in there. The thought of water trickling down her thin but shapely body makes your towel rise slightly, with a sigh you walk back. With Samantha immobilized and still unconscious, John got on-line and called some people he knew in the underground film business. Over the last 6 months, John had laid the groundwork to make a slew of porn films starring Samantha. Her tight teenaged body would be object of their desires while also providing unending hours of sexual pressure. The players in the upcoming films would arrive at his house in a few hours and Samantha would get top billing and their undivided attention for the next. It took a lot longer than necessary for him to click it in, but she didn't make any moves to stop him.We got onto the bumpy main road, and the whole van started shaking and rattling. Somewhere in the middle of the bumping I saw Dave's hands shift from Annie's stomach to her thighs. The two were talking and laughing, but I couldn't hear them over the car noises and the guys talking football.One of the guys turned to me and asked about my football loyalties. I tried to focus on what was going.
