Just hitting up a friend for a threesome, no big deal

You ponder the question as you ride the elevator up to Monica's sixth-floor dorm. So far, your magic cock didn't seem to be changing the circumstances in which you got to fuck the various women you'd had sex with over the last 36 hours, only their willingness. So if you have to guess (and you do), you assume that just whipping out your cock the moment the door opened would get you laid, but not build up much of a lasting relationship with Monica.

So instead, you decide to take a somewhat more tactical approach. "I want you to follow my lead," you say to Ava as you walk down the hall toward Monica's dorm room.

"Yes, sir," she says, smiling.

"Hey!" Monica says from her doorway as the two of you round a corner.

The three of you step inside the small room, and you introduce Ava to Monica. The two of them size each other up.

"Are you in my bio lecture?" Monica asks.

"Ms. Maybelle's class? Maybe... you sit up near the front?"

"Yep, thought so. How'd you end up with a cutie like this, David?" Monica and Ava both smirk at you, and you suddenly start to worry that this was going to be less you and Ava convincing Monica to fuck you than the two of them ganging up on you.

"Mind control, obviously," Ava says. "He's got a way of just talking his way right into your pants." She's smiling as she says this, but now your mind is racing. This is not exactly 'follow my lead'!

"Is that so?" Monica says. "It wasn't him just flexing one of those big biceps of his?"

"No, but I can do that too, if you like," you say, effortlessly and automatically dropping into a classic Schwarzenegger-style bicep flex. You're nowhere near as built as him, of course, but you've gotta admit it's a decent muscle that pops up when you do it.

"Ooh la la," Monica and Ava both say, in unison. They give each other a sideways glance.

"Anyway, no, it's not my biceps. Would, uh-- would you like to know the trick?" I guess we're doing this...

She smirks. "Is this why you wanted to come by, to show me some magic trick you've been working on? Sure, now I've gotta know your mind-control secret."

You hook your thumbs into your belt loops and, with one smooth motion, before she can say another word, pull down your pants, letting your cock flop into the open.

The change is almost immediate. Ava's gaze snaps onto your crotch immediately, her eyes going a little glassy with a sudden onrush of lust. Monica's mouth falls open, and you watch as her nipples suddenly perk up into little mounds through her thin t-shirt.

"I've got a magic cock," you say, almost offhandedly. "When women see it, they feel almost compelled to get me off."

"I-- I see," Monica manages to mutter, still clearly fixated on your quickly-stiffening erection. She looks over at Ava, concern clouding her face. "What about...?"

"Oh, don't worry about me," Ava says. "I'm the one who put him up to this in the first place."

"The more the merrier?"

"Something like that."

"Well, I guess it'd be rude of me to just leave you hanging out there without providing you some... relief," Monica says as she reaches her hand out to gently stroke your cock.

You step out of your pants, pooled at your ankles, and casually tug your shirt off. "You're both a little overdressed for that," you say, and Monica and Ava both quickly move to strip down. Ava, you note, apparently didn't put her underwear back on before coming here with you.

"Well, stud," Ava says, as Monica finishes pulling off her shirt, leaving the three of your naked. "What's first?"
