Sarah doesn't take much convincing

You normally wouldn't dream of being rough with a girl, but too much is riding on the line for you to waste time trying to convince Sarah. With a growl, you grab her head with both hands, and pull her surprised face back towards your crotch. She gives a surprised squeal, but quickly opens her lips and takes your cock back in her mouth.

You're caught off guard, having expected her to resist or fight back. The realization dawns on you that Sarah has a secretly submissive streak in her, and actually enjoys a bit of rough dominance from her partner. You decide to give her what she wants, and, putting your hands behind her head, start fucking her mouth.

Sarah moans around your cock, and reaches down with one hand between her perfectly portioned legs, starting to stroke and finger her pussy as she blows you. Her tongue is practically dancing around your cock, seeming to be licking and stroking everywhere at once, stimulating your head and shaft.

Tom meanwhile is definitely not happy, having missed out on a chance to get in your crush's pants, or worse.

"Well then John, whatever will you have me do for you?" Sarah says seductively, having gotten up, and walks towards you, deliberately swaying her hips. You almost forgot about that part of the deal. As you think of a reply, you're acutely aware of both Matt and Miranda staring intently at you and Sarah, waiting to hear your judgement.

Not wanting to upset anyone else, and having just had an amazing orgasm, you decide on something harmless. "Sarah, I dare you to chug a beer!"

Sarah pouts at such a boring dare, but does as you say, grabbing a can of beer and downing it in one go. "Now then," she says while wiping her mouth, "It's my turn to pick a name, and I'm going to have to come up with a super outrageous dare to make up for that lame command!" She reaches in, and grabs a piece of paper. Its....
