Mistress, of course!

If she's so eager to get her brains fucked out, why should you stand in her way?

You pull away from Sam with a wink, and he smiles back at you. Then he pounces. Mandy lets out a yelp of surprise which is quickly silenced when Sam plants his mouth on hers. You grab his cock and line it up for him. You must serve your master, after all. They waste no time with a slow buildup, instead they set a furious pace from the get go. You sit back for a moment, admiring Sam's ass as his muscles do their thing.

Deciding to get a view from a different perspective, you crawl around to Mandy. As you do so, Sam briefly pulls out so he can flip her over, then plunges right back in to fuck her from behind. You lie down on your front in front of Mandy, face-to-face with her. You wouldn't be able to stand being this close to all that plastic, especially not with the pleasured look on her face, if you weren't so gleefully aware of her impending doom. She looks a little confused by your actions, but doesn't say anything. Mostly because Sam has picked up the pace, and is leaving her little chance to utter anything beyond gasps and moans.

Sam places his hands on Mandy's shoulders and leans forward, pressing her into the mattress as far as her overinflated tits will allow. This is making it very hard for you to decide where to look. Down to where Sam's cock is drilling into Mandy over and over again? His face, to enjoy the mixture of concentration, pleasure and amusement in his expression? In between, to watch his athletic body flex with every thrust? Or do you look Mandy in the eyes, to be sure you don't miss the exact moment of your triumph?

After a good long while, during which you explore all of those options extensively, Sam slows down, then holds in place. For a moment you think he might have came, but he didn't really give any indication other than the change in pace, and certainly nothing about Mandy seems different. Nothing except for the fact that she's found her voice again, at least. "Why did you stop? You didn't cum yet, did you?" "Not yet, " Sam replies, "But I'm just about to. You want to break the news, Cindy?" Oh, fuck yes, you do!

"Have you checked your GAME Tracker lately, Mandy?" "What? What are you- Hey, you're supposed to call me 'Mistress', ****!" You bellow a laugh and pat her on the head. She still hasn't figured it out. "I'm not your ****, you stupid cow. And not Sam's, either. That cannot be said for you, though." She squints at you, then tries to look up at Sam. Finding that she can't, the way he's holding her down, she begins hopelessly struggling against his grip. "What the fuck, Sam!? Did you lie to me!? Get off me!" But Sam doesn't move a muscle. "Careful, Mandy, " he says instead, "Keep moving like that, and you might make me cum." At least she's not so stupid that she doesn't realize the consequences that will have, and so she freezes. She's looking at you with equal parts terror and rage. Not that all that rage will help her, of course. "You lose, Mandy," you tell her. Then you turn your head up to meet Sam's eyes, and give him a wink.

The wink was all the signal he needed, and he begins pounding her again. For a brief moment Mandy tries to struggle out from under him again, but he had held himself right on the edge. Not four seconds after recommencing his thrusts, he groans in satisfaction. The change in Mandy's eyes is immediate. Gone are the fear and the anger, replaced by pure joy as Sam slams into her a few last times, draining his balls into her. Once done, he collapses on top of her, and she turns her head to kiss him. She can't reach his mouth, but seems more than happy to peck him on the cheek as quickly as she can manage.

You feel such unbridled joy that you lose control of yourself. One moment you are writhing on your bed, pumping fists every which way and laughing in triumph, then you are dancing through your room. But beside the joy, there is more. You are hornier than you ever remember being, and need to do something about it right now. You lift Sam up by his shoulders and bodily roll him off of Mandy, only to straddle him yourself. You take his head in your hands and kiss him passionately, which he returns in equal measure. You need more, though, and a quick look down confirms what you had already expected. He might be a stud, but even he needs a little while to recover before he'll be able to go again. You don't have a little while. How fortunate, then, that you have a perfectly willing **** right next to you!
