Stop him. He should save himself for Mandy

"Stop! Sam, stop! Wait!" Frantically, you finally pull your top off your head and look down at Sam. His head is hovering just over your crotch, and he has your pants and panties half way down your thighs. "We can't do this! Not yet! Fuck, I want to, but we can't.

His eyes flick down to your naked pussy, and he sniffs deeply. For several seconds he just hangs there, lost in indecision. Surely he's not considering forcing the matter? But then he backs off, standing up from the couch. He doesn't look as pissed as you expected him to be, despite the blue-balling. "It's fine," he says, "I understand. Once Mandy is dealt with, right? Maybe we'll even have her join us." You feel a brief surge of revulsion at her name, then a stronger one at the thought of having a threesome with her. But then you think of the position she would be in. What you could do with her...

"Done," you say with an eagerness that surprises even yourself. "Once she's your ****, you can bring her back here. We'll have some fun then, I'm sure." You fix your clothing as you speak, though Sam shows no indications of putting his shirt back on. Instead he just watches you get dressed, arms crossed across his chest. "So. Now what, then?"
