Eat a little bit

You dab your finger into his cum and lick it clean. It tastes pretty good, actually, but you don't feel any different. You would probably need to ingest more for it to have an effect. You wipe your finger through the splatters and lick it off, but you still don't feel anything. You lean down and begin to lap up the thick cream from off Jae's skin.

"Hey, hey - Don't do that," the demon says, grabbing you by the shoulder and pushing you away. "What did I tell you?"

"It's not doing anything," you tell him, trying to push his hands aside so you can finish cleaning him off.

"Oh, really?" he asks, reaching down and grasping your still-rigid cock. That's funny, you usually go soft after you cum. He slides his hand along your length and you moan helplessly, the pleasure so intense you can't move, you can hardly breathe. He pulls his hand away, leaving you aching and gasping. "This is just great, now you'll beg to be the sexual plaything of every demon you meet. I warned you that this would happen!"

"S- sorry," you stutter, finding it hard to think about anything besides your cock and burying it in Jae's ass again. "H- how do I make it st- stop?"

"Well, first, stop eating my...stuff," he says, pushing your hand away as you reach out toward him again. He scrapes the pearly fluid off his chest with one hand and wipes it on the floor, and it takes all of your willpower to resist licking it off the stones. "As for making it stop...Well, I've heard that it won't wear off, you have to f- fff-- You know. Until it goes away."

"Fucking makes it stop?" you ask and he nods.
