He fucks you, she rides your face

Mandy climbs onto the bed on all fours, crawling over your body. You struggle against the ropes, but to no avail. "Give up, Cindy. You can't get away. Even if you could get the ropes off, somehow, do you really think Sam and I are going to let you walk out the door? Just try to enjoy it, make it easy on yourself. It's happening either way." She giggles, clearly over the moon with herself, and reaches between your spread legs. "Let's see what Sam has to work with." Mandy gently runs her fingers over your pussy through the thin fabric of your panties, and you just manage to suppress a shiver. Then, she pulls your underwear aside, finding you, obviously, drier than the average desert. "Aww, is the little **** not enjoying herself? That's ok, Mistress can fix that for you. She turns back around, but Sam has already guessed what she was planning and tosses her a bottle of what you assume to be lube. "See?" Mandy crawls back over to you. "See how good I am to you? I could just jerk Sam off into your mouth or something, but I want you to get something out of it as well." She squirts a copious amount if the lube into her hand. "Consider it a parting gift from a long-term rival." "Fuck you, bitch! I'm going to- FUCK!" Mandy has stuck three lube-coated fingers into your pussy, the cold liquid and unwanted penetration both taking you by surprise. "Shh, it'll be over soon." She hands the lube back to Sam, and you see him applying it generously on his dick as Mandy spreads it around your groin. "There."

Mandy crawls up further, then sits down on your breasts, blocking your view of Sam. This close up, you see her triumphant grin as she looks down at you. Though you can't see him, you feel the bed depress between his legs as Sam takes his place. Then, Mandy scoots forward a little further, so her pussy, glistening in the light, is hovering over your face. "Oh, hell no!" You shout. "If you really think that I-" Your words are cut off as Mandy lowers herself onto you, blocking off your mouth. At the same time, Sam slides his hands onto your ass, positioning himself. Then, he thrusts in, the task made easy by all the lube seeping out of you. You scream in panic as you feel him enter you, but the sound is muffled by Mandy's pussy. "Mmm, do that again!" She begins grinding against you, forcing you to breathe in her smell. Between your legs, Sam is starting to thrust faster and faster, and you can't help but moan into Mandy, who seems to be enjoying herself greatly.

An idea strikes you. One final chance. Maybe. You twist your head to the side as hard as you can, freeing yourself from Mandy, at least temporarily. "Sam!" you shout, "I challenge you to a GAME!" Mandy grabs onto your head, trying to turn you back into place. "I challenge you to cum inside Mandy instead of me! If you win-" Mandy presses her labia against you again, but you bite into them, eliciting a very satisfying yelp. "If you win, I'll let you fuck me whenever you want! I'll have to come over at least once a day if you want me to!" "Shut the fuck up, bitch!" Mandy is getting very angry now, which may not end well for you. "If I win, well, I'll be your **** anyway. No prize for me! And no forfeit!" It's as sweet a deal as you can offer. A **** and a half, instead of just one, risk-free. Mandy finally gets your head facing upwards again, and presses down on you again. "I have a better use for you tongue, ****!" She starts grinding on you again, but behind her back, Sam has stopped fucking, his cock fully inside of you.

Note: If you are using game mode and only see a single option, maybe you can try being a little nicer to Sam? Maybe let him 'sample the goods', as it were.
