All in: Take her on the couch

"Get on all fours on the couch Kate, now." Kate walks over and bends over the couch, her ass sticking up in the air, beckoning for your cock. You can't resist, you hands unclasping your belt. You walk up behind Kate, and her ass a slap. She gasps, looking back towards you with those big, innocent green eyes.

"What are you going to do?" she asks, a waver in her voice.

"I'm going to fuck you, and you are going to orgasm when I tell you to." You position your cock between her lips, and nudge the head into her. "Now orgasm."

Kate screams in surprise and pleasure as her orgasm washes through her. You thrust into her, your cock pushing against her walls. She screams again, as you bury yourself in her tight, still sensitive pussy. You begin fucking her, giving her ass another good slap. She moans, as you pound into her, her now-glistening pussy coating your cock. As you feel your own orgasm building, you pull out, flipping her onto her back and positioning at her entrance.

"Kate, each thrust will bring you to the edge of orgasm, but you will not fall over that edge. Not unless I tell you to."

Kate nods, and you push into her. She gasps, "I'm going to cum again, oh my god." Again. "I'm going to cum!" Again. "Oh I'm so close!" And again. But although on the edge, Kate cannot seem to orgasm. You continue, and with each thrust Kate gets more ****. Her hand moves down to rub her clit, her legs squirming. "Please, John, let me cum, its ****."
