Does it matter?

You're going to get it out of him, no matter what.

Fear fill his eyes. He shakes his head violently, and tries to get you off of him, but he just doesn't have the strength. "No. No, get off of me, you crazy bitch! I've got no more!"

You smirk at him. Crazy? He hasn't seen crazy yet. Lifting your hips straight up, you drop yourself onto his cock, taking all of it inside you and clamping down tight. His face tightens in a grimace as you expertly squeeze down on it in sections, milking him from base to tip, and then forcing it back down the pipe, only to send it back up all over again.

All the while your hips are rolling against his, and the look on his face is absolutely delicious. "Oh fuck... oh yes...," you groan, almost getting drunk off his essence. "Oh yes, this dick is so good. Oh... give it to me, give it to me, give it to me... oh fuck, I love it..." Dropping forwards, you smack your forehead onto his and glare at him, madness dancing in your eyes. Your hips become more desperate in their movements, but you know exactly when you need to hit the pleasure button and make him groan. "This is my dick now. You're going to fuck me whenever I want. You're going to be hard for me forever. You're going to fill me up every time. Just like this. Just like this. Oh yes... oh yes..."

The madness is met with terror. His breathing is short and you can feel his frantic heartbeat through his cock. Grinning maniacally, you straighten up, prop yourself on his legs and get your feet under you. You give him a beat, just so you can marinate his essence with horrified anticipation, before bouncing violently off of him. "OH FUCK YES!" you howl, backed by his agonized scream. "I LOVE THIS COCK! I LOVE IT, I LOVE IT, I LOVE IT!" You briefly consider dropping the illusion and letting him see your true form, but somehow, this feels like it's going to be funnier in the long run if you don't. Looking down at his rapidly thinning body, you turn all of his buttons on and grind on him hard. "CUM! CUM FOR ME! CUM IN ME!"

With a wheeze, he falls limp as his cock pumps liquid essence into you. Your head rolls back and you breathe heavily, running your hands through your hair. That was the closest you've been to actually cumming in centuries, but damn if it wasn't just as good. You feed of his essence, leaving him enough to stay alive, just in case you might want to have another romp with someone that's not your host, before clambering off him.

Leaving him as he is, you roll your shoulders and summon a mirror. Giving yourself a quick touch up, you put your clothes back on, blow him a grateful kiss, before unsealing the room, going invisible and immaterial, and letting out a blood-curling scream of terror. And as you've expected, Izu and the manager are first to arrive. As you skip through them, you hear Izu go "Raf! Raf! What happened man? Where's Irene?! Raf!?"

A tremor rolls up your spine, and your knees go weak. Fuck. That really is better than sex.
