Use your powers to arouse him.

You can't influence free will, but you can manipulate a persons senses. His cock is already in his hands, all you need to do is make it more sensitive. You look down at his cock and concentrate. Almost immediately you see it begin to engorge. The guy rubs his hand along the shaft, surprised by how good it suddenly feels. He stops when he realises you're watching.

"See" you say to him. "I told you you were playing with it". You grin, licentiously.

"Dude, what the fuck! You checkin' out my dick?" he asks. You know that by now, his arousal is at unusually high levels.

"Relax man!" you say "I'm not gonna tell anyone you're jacking yourself off at a party" you laugh.

"Fuck you man, I'm not jerking it!" he says defensively, though his hand is still grasping his engorged cock. In a moment of inspiration, you quickly dial down the sensitivity, leaving him aroused but unable to satisfy himself. He turns away from you and you can tell he's trying to rub himself harder and you know he's not having any luck.

"You want a bro job?" you ask, slyly.

"What?" he asks, his face flush with frustration.

"You know, one guy helping out another guy?" you say, your tone almost condescending as if it's something he should know about.

"Oh...yeah..." he says, blushing slightly "you gay?" he asks.

"Nah man, it's not a gay thing. Just one bro helping out another bro" you say reassuringly. He seems to relax a bit, buying into the premise.

"I guess that's OK then" he says, turning around. His cock is now fully erect, about as long and thick as yours. You lock the bathroom door and make your way over to him. You stand in close.

"You ready?" you ask. He nods, avoiding eye contact. You reach down and grab his dick, which he lets go of. You restore his sensitivity with a thought and he takes in a deep breath as the pleasure returns. You begin stroking, causing your partner to moan slightly.

"Fuuuuuuck, that's good" he says "...are you..." he begins.

"Am I what?" you ask bluntly.

"Are you gonna...you know...suck it..." he asks bashfully.

"Do you want me to?" you tease. He looks at you and looks down at his cock meaningfully, obviously wanting you to. "Sorry, I didn't catch that, what is it you want me to do?"

"Suck it! Suck my dick!" he begs. You smile and drop carefully to your knees. You lean your head in and playfully flick the tip of his cock with your tongue. "Ohhhh, yeah man, suck it for me" he asks, driving his hips forwards.

You open your mouth and allow him to slide into your mouth. You enjoy the taste of the salty beads gathering on his tip. You wrap your lips around his girth and draw him further into your mouth, sliding him down your throat until your nose pushes into his pubic region. It's child's play for you to suppress your vessels gag reflex.

"Shit you're good at this" he gasps appreciatively "my girlfriend doesn't suck it as good as this."

You work your head back and forth, up and down his shaft, lashing your tongue around the tip as you go. You grip his hips and pull them towards you, prompting the guy to begin fucking your throat. After a few pumps you feel him tense and then feel a hot gush hit the back of your throat. He continues to pump as he unloads himself, groaning with ecstasy. As the seed enters you, you feel a rush of power with it.

He pulls out of your throat. "Dude, that was amazing" he says.
