She was only about 5'2" and probably didn't weigh more than 100 pounds, but she was a nice set of tits, probably a b or c cup, and her hips made me qu...ver with excitement as dad was giving her all she could handle. As he was sucking and kissing on her clit, I put my hand into my shorts and had began to stroke my cock. I was so turned on seeing my dad and little sister go at it, with dad occasionally breaking stride to kiss her lips and stroke her hair. My mind was filled with questions as I. He sighed with pleasure as I stood behind him and slipped both hands into his pockets, as usual he wore no shorts under his trousers and my hands quickly found his semi-erect penis,"It's all yours mum" he said softly as I stroked him gently and fondled his freshly shaven testicles,"I want this in my mouth" I whispered, "And your balls too"I felt his hand finding the side slit in my dress and his fingers touched the naked flesh above my stocking as I masturbated him slowly,"And after I've. This time the session was pretty dull, 30 minutes of him lying tied, the30 minutes of where I entered with the vibrator and took his cage offand then the final 30 minutes where he was left at the end. I ended upjust adding 5 number cards at random intervals throughout. I would havehim watch it in his room later to get him out of the way when I hadfinished with him. The number cards meant he couldn't look away from hishumiliation, he would have to watch the whole thing as if he didn'trecite all. I imagine a few minutes went by, and then I pulled out of her completely and put my hands on her hips more gently. Her bottom rose into the air as if to seek my penis again, but it was just beyond her reach. I then turned her round again and put a hand on her heaving chest, positioning myself with the other to enter her missionary-style. I looked at her face: her mouth was hanging open and her eyes were closed. I teased her, stroking up and down with my tip, for a few seconds, and then pushed.
