As she was not that beautiful, I was hesitating a bit but then I saw her big cleavage and just gave her a smooch, we kissed like crazy for 10 mins, me...nwhile, I pressed those big melons very hard making her moan loud in pain.After that, we moved on the bed. I was on her kissing her and pressing her boobs, after some times, I started undressing her, removed her top, her bra and pant and panty, she was naked and was looking, sexy with those big boobs and that ass and hairy pussy, I was about to. He moaned. I think I did too. Then he rolled back over on his back.I laid down on him and kissed him. It was really exciting to have my tongue in another man's mouth! I worked my way down his body until my face was resting against his penis. I stroked the head of my cock rubbed against his calf, and kissed and licked the head of his penis as he massaged it. He was squirming with enjoyment.Then I had an idea. I got a handful of Vaseline, then spread the guy's legs apart and kind of scrubbed his. Taking my excited cock in my hand I found the entrance to her fuck hole. “Fast and hard Paul, fuck me fast and hard.” With one fast hard shove, I buried myself fully in my sister’s hungry pussy. She groaned loudly. I bet the people in the next room could hear us. I started pounding away at my sister’s cunt which made the bed headboard bang the wall. I knew they could figure out what we were doing but they would have no idea that we were brother and sister.After the sucking Janet had given. He caught me looking at it, and stared me down, smiling. He knew from the start how naughty I was, and he loved that about me. He aggressively pulled my toned legs towards him and wrapped them around his waist. Impatient, I started to unbuckle his belt and unbutton and unzip his trousers. As much as I loved the shirt, it came off too. I was now one layer closer to him as I lay down, but he was still wearing his white underwear. His dick under the thin cotton was so close to my open wet pussy.
