His eyes were on her upturned ass, but, bending and twisting in front of him, she felt the pose in her stomach and the small of her back, in the muscles that stabilized her just slightly spread legs. Her hand swept the fall of her loose curls from where they poured over her face and continued the stroking motion over the small bumps of her breasts, giving a lust shiver.
She couldn’t see his face like this, not with her back to him and him tied to the chair, but she heard the noises he made and could imagine what he saw, knew her body well enough to know that her ass was, in her estimation pretty awesome.
She wondered if he focused on the fullness, because with her hips it was wide and heavy. If he wasn’t restrained, he could take it in his hands, one on either side, and dig his fingers in and fill his hands, fingers sinking in just a little. Or, perhaps he paid more attention to the contrasts, the way her waist bit in and then suddenly belled out below, like an invisible corset had cinched her in around the middle.
Or maybe he liked to see the cleft between the halves of her ass and the way the split led down. Putting he hand on her hip she thrust her ass out higher, pulling slightly to spread herself. She wanted him to look at her, to desire her, and, holding him captive this way, she teased herself as well, imagining he was loose from the cuffs that locked his arms behind his back. He would stroke the feathery hair on the vivid pink slash of her cunt, find the sticky dew that gathered, and pet with two fingers until her cunt welcomed and engulfed them.
She liked it, liked giving him liberty that way, to feel his hand smack into the unblemished white of her ass cheek, just enough to tingle, and feel herself devouring more fingers. Sometimes he talked, speculatively and teasingly, of the day her cunt would eat his hand up to the wrist.
And sometimes, more carefully, when he had her humming with desire, his fingers would wander to her ass again, and tease their way inside. The intensity of just one or two would always pushed her orgasm to somewhere beyond the usual realm.
But, right this moment, it was her own fingers playing with her cunt, opening herself for him to look but not touch. It was clumsy at this angle, but, his little intake of breath was worth it, as was the creak at he pressed himself back into the chair. Coyly, she pivoted to look over her shoulder. “I’m going to sit in your lap now.”
She settled herself with more than the necessary amount of wriggling, aware of her bare ass pressing against his cock. The width of her hips filled the span of his lap, nestling her snuggly into the space where his arms were bound to the chair. Resting her own arms on top of them, she sighed contentedly and then began to swivel about on the spot, grinding and rubbing up against him.
“What,” she smiled, “Is it worth to you to be inside me?”
