Erwin waits for Levi to come back to himself, watching him with a lazy, satisfied expression. Seeing the slow come-down, the way Levi gradually relaxes and unspools, is almost as enticing as the actual act they've just performed. It's especially good because Levi so rarely lets himself relax, lets himself be undone. The fact that he trusts Erwin enough to let him get so close is turn-on enough on its own.

"No, there's no one here but us." For the first time, Erwin pays attention to his own groin, which is wound tight as a spring and aching. Yes, he enjoyed that just as much as Levi, but without the release at the end. His cock is tenting the front of his pants, and throbbing along with his heartbeat.

He leans his head into Levi's hand, closing his eyes and smiling for a moment. "I may ask you for a literal hand in a few moments."

Even more pleased with his dumb joke, Erwin gently pushes back and stands up. The motion makes the tent in his pants obvious, but he ignores it, instead turning and heading towards the bathroom. "But right now, I'm going to go brush my teeth."

He's not bothered by the taste or gluey feeling in his mouth at all; in fact, Erwin rather likes it. He knows, however, that he's not getting any kisses or cuddles from Levi until he cleans things up, so it's off to the bathroom for a quick brush and gargle.
