"Ohhhhh, Scotty," she moaned in a low tone of voice so that her brother could not hear her. Then, she raised her voice. "Hurry, Biff, fuck me now!"Bif... slapped his sister's ass hard several times, leaving his red handprints on her lily-white flesh. He grinned and pushed the throbbing head of his prick into the hairy mouth of Gail cunt. He surged forward, stabbing the first few inches of his cock into her."Yessss!" Gail hissed.Biff groaned with pleasure, loving the feel of his sister's hotly. The closer I got to the room, the louder the noise got then I could pick out my wife's voice above the rest of the noise. Just a few steps away from the door, it finally hit me. The sounds I was hearing were the sounds of sex. Two people going at it hard and heavy on a bed. At first I thought my wife was being attacked until I clearly heard her yell, "Fuck me, Oh God Yes" over and over.The door to the bedroom was slightly ajar and the noise from my wife having sex with someone other than me was. I had a quick look up at his face - he still had the cutest and most innocent smile on his face - my hands slowly pulled down the black boxers that fell on the floor - and in front of me was now his soft uncut manhood! At least 20cm dangling in front of my face ready to be played with...Slowly but determine I licked the tip of his dick pushing his foreskin back with my tongue. As his soft dick slowly became harder so did my pace. I held my hands around his thighs and onto his ass forcing his. He rested deep inside me for a few moments. “Does it feel nice?” I asked. “Yes” he whispered. “Ok I said, you can start fucking me now, slow for a little while, until I get used to your cock. He did what I said, easing almost all the way out and then easing back in deep. Long slow strokes, his warm hands pressing on the small of my back. In and out slow and steady. He had a rhythm. His cock filled me. Each time he withdrew it felt like he was coming out, but he never did. It was beautiful.“Do.
