He also slapped my hips and legs, almost anything he could reach. He was beyond control now, just growling like some kind of Wildman. He then pushed...me off and told me to lay on my tummy and I did and he slid his cock into my ass again and pinned my neck down and began slapping the back of my head. He pumped so hard and after a few minutes came in my ass. He moaned, almost yelled when he did…the kind that a man does when he cums harder than he has before. He then pulled out of me and laid. His chin sank with shame onto his barechest, for he knew that his Mistress was right and it was his miserablesubmissiveness to her clothing that had made him disgrace himself acrossher black pencil skirt."I... I'm so sorry, Mumsie, yes, I..."She tightened her grip with both gloves, bringing him to a halt with a"Yipe!" Is my lickel baby boysie forgetting to talk to his Mumsie in a pwopersissy voice when she is cuddling his sissy lickel popsie, den?"His penis was stiffly erect in her hands as he. Why should I mind if you look at my body. You wouldn't mind if I looked at yours, would you?" Darlene waited hopefully for the answer."Well, of course not," he blustered and it wasn't two seconds later that the boy had tossed back the covers and was standing as naked in front of his big sister, as she was in front of him.For almost a minute, the two siblings just stood there, staring intently at each other's naked bodies. Darlene, while not yet at full womanhood, was definitely developing into. He then moved to flick and massage my clit while he moved two fingers, then three into my cunt. I rocked into him hard and I felt that incredible swelling of an orgasm growing fast. I clenched onto the sheets under me as I prepared my body to cum hard and long. Oh, dear god it was fucking amazing and I heard his moans of approval as he slurped up my cum. He wanted to make me cum again as he slowed down, but was deliberately working my pussy again. It was hard to pull him away and selfishly hard.
