Focus on Will.

Seeing Mike getting so into his roommate's ass (or pretending to) is cute, but for the moment you'd rather focus on Will.

"Mike, since you're so attracted to me, would you rather do everything I say, or leave the room and forget about this whole experience?"

You can tell from the expression that crosses Mike's face that he desperately wants to choose the second option. However, he's already made his choice: he has to pretend that he's in love with you. "Do whatever you say," he whispers.

"Then stop what you're doing," you say.

He pulls his face away from Will's butt and stops jerking off.

"I'm going to be taking over from here," you announce. "Will, come to your own bed. Mike, you keep sitting there."

You dig through Will's laundry and pull out another pair of underwear. This one has what looks like a small cumstain in the front.

"I'm about to fuck Will up the ass," you say, "and when I do, I want you to sniff this pair of underwear while you keep masturbating with the other pair."

Mike nods.

"Wonderful. Will, bend over."

Will hasn't pulled his shorts up, so his butt is still bare and ready as he stretches across his bed.

"Would you rather your asshole be clean and self-lubricating and fit my cock perfectly, or would you rather anal sex be uncomfortable for you?" you ask him.

"I would rather my asshole be clean and self-lubricating and fit your cock perfectly," says Will.

That's all you need to hear, and you pull out your dick at once. Across the room, you hear a sniff, and you turn to see that Mike has already shoved his face into Will's soiled undies. Smiling, you plunge into Will's asshole. Will moans.

It's the first time you've had sex, and it feels amazing. You bend over Will's body and lift up his crop top, revealing the whole length of his tan and muscular back. You wrap your arms around his front, feeling the slight prominence of his pecs, before moving your hands up to hold his chin. As you thrust deeper, he turns around, showing you a look of appreciation from behind the purple fringe of his hair.

It's an amazing sensation, made all the better by Mike's shameful and **** masturbating in the other bed. It's clear from his rapt expression that he wishes he were the one getting taken and not Will. But he has ****. With one pair of undies over his face and the other shoved down his pants, all he can do is enjoy the show you two are putting on.

You caress Will's head, pulling it up as you continue to pump from behind. "Harder," Will says.

It's odd that he should say that when you never told him to. You realize that he really is in love with you now. So you go harder on him. After the last choice you gave him, his butt has become incredibly resilient, so that no matter how hard a beating you give it, the only moans that escape his mouth are moans of pleasure, not pain.

You let go of his head to move your hands down to his penis. It's stiff and throbbing and apparently seconds away from orgasm. You give him a little help. Taking his cock into your hand, you stroke in time with your own thrusts until the both of you start to cum. Will's semen shoots across the bed while your own shoots inside his ass. For a moment, you forget about all the changes you've made and ease into a blissful enjoyment of Will's body.

When it's all done, you look across the room and see that, through some miracle, Mike has cum as well. With a shameful smile on his face, he pulls Will's cum-soaked briefs out of his boxers.
