Oh that's more like it. Byleth's mouth curls into a satisfied little smile. He can see how his cock is jumping and twitching, clearly on edge.

"You wanted to come, didn't you? It's all right. You can do it. After this, I'll let you come all you want." A promise and a threat. He doesn't let up, and the other quill is taken up to his lips, sliding the tip of it against his tongue, wetting it just so. Enough that when he brings it down to trace along the underside of Emet's neglected cock, it ought to feel at least something like a tongue, though far less substantial. It should be enough to bring him off eventually. With how much teasing he's done, and how wound up they both were when they came in.

"Just let it happen. No need to fight it. Wouldn't it be fun to tell Hythlodaeus you got off from little more than this? Oh I'll bet he'd never let you live it down. Of course, neither will I." He muses happily as he grants no mercy but the gentle encouragement and backhanded teasing comments.

"Wouldn't you have loved to be on that stage right now? What a spectacle you are. I'm sure that would give people something to chatter about."
