There was never really any doubt.

Matt looks as pleased and eager as you would be if it were you and Miranda were standing in Sarah's place. "We shall, my lady." Matt grabs her hand and kisses it in a mockery of old time civility. "Get in that closet, we're going to have some fun."
"You should probably pull a name and make a dare before you go..." Nicole pipes up.
"Yes, I should..." Matt leans down to pluck a name from the hat. "What a coincidence. Nicole." He smiles. "Since we're going to be occupied for a while... why don't you spend 3 minutes each making out with John and Tom? Miranda, you can keep time for her."
"I'll already be keeping time for the two of you, so that should be no problem!" Miranda smiles at Nicole, who has a look of trepidation on her face.
"What? I..."
"Oh, come on, Nicole. This game was your idea. What did you think was going to happen?" Miranda gives your friend a look of confusion. You are torn between wanting to agree with your crush and wanting to protect your friend, so you stay quiet.
"Dare's a dare." Tom says.
"For once in my life, I agree with Tom." Matt nods. You try to feel mad at him until you sheepishly realize that a: he doesn't have the history with Nicole that you do and no instinct to protect her like a little sister. and b: it was Nicole's idea to play this game.
As Sarah and Matt head into the closet, Nicole looks at you, trying to boost her confidence. "Well, I guess it's best if I start with you, John." She doesn't seem afraid, only a little awkward as she gingerly climbs into your lap, draping her arms around your neck and staring into your eyes. She really is quite beautiful, and this game of dares seems to be stripping all your inhibitions away so that you can really appreciate her in that way. Her lips are quite kissable, you decide: slightly pouty without being overly plump, and bearing a faint strawberry lip gloss. You begin to wonder what she will taste like.
"I'm not very experienced at this..."
"It's okay. I've got you."
"Go...and go!" Miranda shuts the closet, and Nicole begins to kiss you. She starts softly, just pressing her lips to yours, only parting them slightly. Her lip gloss is sweet and her breath is warm against your mouth. Her arms slip tighter around you as she takes her first, tentative explorations with her tongue against yours. To your surprise, she begins to moan softly as you make out, and you feel her fingers run up into the hair on the back of your neck. For being inexperienced, she seems a natural kisser. You can't stop your cock from beginning to spring to attention, and you hope she doesn't feel it starting to bulge up against her ass.
"Time's up!" Miranda calls out. "Time with Tom begins in 30 seconds."
"Thanks..." Nicole whispers, and her eyes are shining as she parts from you. You feel a little stunned at the intensity of the moment you just shared with her. You shake yourself, trying to remember it was a dare. She climbs into Tom's lap, and he immediately pulls her close to his chest with a hand on the small of her back. "Let me show you how a real man does it, Nicole."
"...and go!"
You suffer silently as Tom kisses Nicole forcefully, grabbing her ass and grinding her against him as he takes charge. She is more the receiver than the giver in this exchange, and her whimpers are less moans of pleasure and more protests of discomfort. Tom's hands are very active, running up her back and down her curved hips, and finally gripping the back of her neck to really go to work with his tongue in her mouth.
"Time!" Miranda yells. And then gets up to run to the closet. Nicole pushes herself off Tom.
"Did you like that? Making out with a real man?"
"A real pig!" Nicole spits. "If it wasn't a dare, I'd never have done that!"
"You just need more time to get used to it. You're still green. Don't worry, I'll teach you." Tom stuck out his tongue and wiggled it, while Nicole returned to her seat in disgust.
"Asshole."
At the closet, Miranda pulls open the door to reveal a red-faced Sarah. She's not wearing pants anymore. She might not be wearing panties either: her only article of clothing is the shirt that Matt had been wearing, stretched over her big tits and hanging to just about mid-thigh. She grabs her pants, panties, and bra from the floor of the closet before letting Matt out behind her. He's red-faced as well, obviously bare-chested and buttoning his shorts.
"My clothes got in the way...."Sarah smirks, dropping them on the pile and dropping onto her seat in such a way that she was nearly flashing the whole room before she crosses her legs seductively and tucks them under her. Matt returns to his own seat and puts his hands behind his head, a contented smile on his face.
"How did the dare go?"
"Just fine!" Tom smirks.
"Half of it was great!" Nicole says right on top of him. She turns, and gives you another thankful smile. "Half of it was."
"Well then." Sarah hands the hat to Nicole. "Pick a name, any name!"
