“You’ve got great tits, Miss Ginello,” he told her.Tits! She had tits now, wasn’t that funny? Hooters, mellons, tatties, boobies! Nice ones, t...oo. Tom had said so.“T-thank you,” she said as he squeezed and fondled her through the ill fitting men’s dress shirt. “but this isn’t right. We shouldn’t do this.”Her right breast popped free from the shirt. Why had the buttons come undone? Oh, because she was currently unbuttoning them. Wait a second, that wasn’t what she meant to do, and why was she. There were no groans of pain from the arthritis, or even any slowness. She reached down and fed my cock into her hot, wet pussy and started to move up and down. I pushed her nightie up so I could put my hands on her naked hips. She reached down and took hold of the bottom of her nightie, with her arms crossed the way women do. She lifted her arms and removed the nightie. She sat astride me, completely naked for the first time in many years. I looked at her body. Her tits swung as she rocked. She has always liked how it prods her when they are naked and kissing. The feeling is so naughty, made even more so because they are siblings. She slides her hands down over his broad shoulders, down over his now furry chest and then down his sides. The sensation hovers between ticklish and intensely erotic. Her hands eventually come to rest on his hips to pull gently on him, increasing the friction between them.Carson breaks off the kiss, pulling back a little to look at his sister again. She. He then moves slowly under the covers until he is lying between her spread legs, his head is even with the top of her legs. He slowly pulls the covers down further, as he wraps his own arms gently under her legs. She is now held firmly, his head positioned at the apex of her legs. He inhales deeply, sensing the arousal that already builds within her still sleeping body. Soft kisses, planted on her legs and upper thighs. Tongue touching, tasting the skin, the slight sweat of sleep, slowly.
