It made me horny again. I slowly tried to slide in my dick in her asshole. But it was tight.We went to the bathroom and applied shampoo and slid it th...rough her asshole. It was really painful for her but she didn’t want me to stop. Her crying changed to moaning. Then I increased my pace and started ramming her ass. She was screaming at the top of her voice.I was being turned on by her voice over and over. She was really a bitch. I pulled my dick out and took her boobs in my mouth and started. Then she glanced at me with a strange smile.I felt nervous and instantly unsure of what I had happened. The movie went on but for some reason Angela would glance at me from time to time, with the same little cute smile. Amazingly, I could see her little nipples become firm under her tank top.Shortly after I found myself staring at her chest, the movie ended.Sarah sighed and uttered, "I'm fucking tired Angela, lets chill in my room. I mean lets go to bed!" Then my sister got up and went to her. I heard her tell Max on one of the recordings that she was only worried about still being able to make the fuck films while she's pregnant. Max told her that she would be paid even more for making the videos when she was pregnant. It seemed that those types of movies were in high demand by all the perverts out there.I continued to watch my videos of those men fucking her. As much as I liked seeing their big cocks ramming her pussy, my favorite thing was seeing their big cum loads draining out. Then there was a young man Millie had dated when she was in trade school. That young man had pressed the issue of sex, telling her he loved her until finally she had given in and he took her virginity. That was very quick the first time. After that, there had been a dozen or so sessions of sex, Millie found that she really did enjoy it and she finally got to touch one. But one day he had become bored with her and moved on. That was very close to the time when her Mother had passed, all of that.
