I stared at her boobies. Not big. Not tiny. Just a good handful. Not that I would know. I was a virgin. My knowledge of sex was looking at magazines a...d watching videos on the computer. But to my inexperienced eyes her breasts looked fabulous. And my penis obviously thought so as it was twitching furiously inside my boxers.My sister must have noticed this. She turned away from me, shook her ass, then pulled down her panties. She turned round, her hand covering the space at the top of her legs.. Just when I was about to cum, I stopped and asked her to turn around. Instead, she got up, pushed me on the bed, and started riding on me. As time went by, she started riding me harder and harder.To be honest, I was hurting a little because she was riding a little too harder. But pleasure took over the pain, as usual. I could see her sweating and getting tired of riding me. I asked her to switch and pinned her down.We then fucked in missionary for a while, and she had an orgasm. I could see her. Amy could do nothing but sit as a mere puppet and enjoy these new feelings. Lisa then ripped apart Amy’s underwear, rubbed Amy’s cunt for a few seconds and then brought her digit close to her mouth and licked off the sticky liquid. “mmmmmm…you do taste delicious Ameline!”, exclaimed Lisa. She wasted little time in lying on her back and pulling Amy by her hair, and burying her face right inside her wet, sopping love hole. She barked, ”lick me hard and lick me well Ameline, show me how good you. His descent was in slow motion, the silly waving of his arms, like an ostrich that thought it could still fly. And seeing clearly his trajectory, how to land on the floor he would first have to go through a full truck of books, I was praying please don't break your neck, please don't break your neck.Then things speeded back up. The truck squealed on its wheels, then tipped. These train-wreck long loud noises as books flew everywhere and Ethan and the truck crashed to the floor. I thought he was.
