She would be nervous, but curiousity always got the better of her. She was never sure, but he was. He'd convince her how much fun they could have. He'... teach her everything he knew about that mysterious, forbidden world.Their reality was much different. They had parents, uncles, aunts, cousins ... They were hardly ever alone. Uncle Fred, Lydia's father, for one, was almost always around. He'd want to take the boys -- Donald, his brother, Dennis, and Lydia's brother, Alan, out fishing, riding,. His smooth fingers wiggled back and forth inside my ass, it felt so good. Once it was ready, he pressed his head against my asshole. I put my hands against the walls for support. Slowly, he pushed his way into my ass. I let out a huge groan as his large cock went into my small hole. "Oh, Jenna, you're so fucking tight!" he growled. He squeezed onto my bum cheeks as he softly began to thrust his cock. It felt so odd, yet excitingly pleasurable. I moaned a little louder as he went further into my. I slid my hand into my shorts as they continued, rubbing my cock as I watched, when my sister Lisa tried to open my door. The chair I was standing on had the door blocked, I quickly got down and opened the door, whispering to my her to be quiet and let her in, then told her what I had seen, putting the chair back under the vent so we could look some more. We took turns looking for a few minutes as they continued to play with each other. Lisa was up on the chair watching them as I stood behind. Sara tensed at first and then started to moan even louder. Yes, lick my asshole please she said. This has never been something I was into, but this was one of the most torrid moments of my life. I continued to lick her asshole then moved a finger up to it and began to push it in while I went back to sucking her clit. Sara began to sob once again and grind her pelvis onto my chin. She shuttered, tensed up and screamed with my cock in her hand. Once again her pussy filled with more fluids.
