I pushed down on the top of his head, forcing him into line with my crotch. “Lick.” He hesitated. “I said lick! And don’t pretend you haven’t done this in half your sick fantasies. You’ll enjoy finally getting at your sis’ sweet twat. Now, lick!” To be honest, he was a bit rubbish at cunnilingus, lapping at my crotch as if he were cleaning a plate – and no doubt tasting something worth the lapping up. My cunt had felt a few tongues in the last few days, and while he was not the worst, he was far from the best. The racy sordidness of the situation more than made up for it though, and my chest started heaving with the beginning build toward climax. Besides, a few words of firm guidance, supported by my directing hands on either side of his head soon had him hitting more of the right spots. He could be trained! I had confidence that, with practice and my precise feedback, he had become a fairly decent pussy-licker. The very fact that I was even thinking that way gave me a little illicit thrill when I realized it. This time, though, with my oral masseur in my thrall, a whim caught me and I decided to take it a step further. Shifting slightly to rest more on my tailbone, I pressed down on the top of his head, pushing him away from my clitoris, down across the perineum to my puckered pink arsehole. It was too much for him. With a lurch, he backed away a foot or so. “Eww, you want me to lick you bum?! That’s disgusting!”
