Our family is really open, as you may have guessed, and we’d always run around nude around the house. Our parents taught us that masturbation was na...ural and not a big deal, and certainly nothing to be ashamed of. So it didn’t bother me that the door was open and as Sis passed by the door she could look over and see me whacking off. As it turned out, she wasn’t interested, and never even looked into my room.But I sure looked at her. Mom and Sis had great bodies, and they both always turned me. When she stops for a minute, her hands now on his shaft jerking him, he lowers himself to his stomach and tells Emma to go back to how she was positioned earlier.She quickly does as told, on her knees, butt in the air, wondering why he wants her this way again already. In seconds she knows. He is between her legs, on his knees, and pressing his hard cock up along her slit. Teasing her clit, wetting it well, and then ‘yes, yes, yes,’ he thrusts himself in her as deep as he can.In this. (I doubt I was the only one)Will lowered her onto the bed on her back, her ass just hanging off the bed as he spread her legs, his now-glistening cock again disappearing inside her,Bella clasped on to the covers as she took his full load, her tits bouncing as he slammed into her, letting out a cry of ecstasy , her legs tensing with his thrusts.The sound of the bed shaking took my mind of the rain, as Bella's still wet hair clung to her face, her eyes closed, and eyebrows raised... An expression. A pain that would normally cause me tostop and never do it again, but I wanted, needed the release so muchthat I carried on after that short pause. I was eventually bucking andthrusting in mid air until my inner satisfaction eventually came onceagain. All through it my entrapped penis had throbbed and buzzed,begging, screaming, for its' release until that finally achievedseemingly longer to achieve climax.I lay there feeling weak, my eyes closed my heart still throbbing, deepdown I felt mixed.
