Marie

The bottle lands on Marie.

"Marie, I think the boys are starting to gang up on us, so let's even things up a bit. I want you to strip Bill and John naked, sit between them, and stroke their cocks until the hourglass runs out or they both orgasm. If both of them cum, you get to spank the one who cums first 10 times. If either one holds out until the hourglass runs out, he gets to take off your bra and suck your tits for another length of the hourglass. If both hold out, they get to strip you to just your panties and lick and suck your whole body."

As Marie gets up and starts walking over, you find yourself wondering if you could possibly hold out. Between the arousal level caused by the last few dares and the thought of what will happen if you hold out or cum first, you're pretty sure you might cum from Marie's first touch. Thankfully, you get a moment to compose yourself as she approaches Bill first. She moves quickly, divesting him of his pants and boxers and gently tugging his erect cock once before she makes her way toward you.

As Marie jerks you toward her by your waistband, you try desperately to think of anything non-sexy, but her bra-clad breasts fill your vision and it's hard to think of anything else. When you finally manage to think of something else, it's Chloe in her thong. You're really starting to doubt that you can hold out. Marie pulls your shirt up over your head, scraping across your chest as she does, then roughly pulls your pants and boxers down. You oblige by lifting your feet to help her remove them. She walks both you and Bill over to the couch and sits down between you. "Ready, and go!" you hear Chloe say. Marie's hand starts stroking your cock and you can already feel pressure building. The grunts you're hearing from Bill's end of the couch tells you he's likely in a similar state.
