"Then hear it. I will promise to try and not break it." A compromise. It isn't a promise he can commit to fully, not when he could take it off so easily. He does not feel the need to explain it- Hythlodaeus knows him extremely well after all, and how his patience would begin to wear thin if drawing it out began to morph in to actual frustration.

When his lover speaks again it is met with a fleeting smirk, both his arms wrapping tightly around his neck for support as Emet-Selch lifts his head up, foreheads resting together. Half-lidded eyes have their gaze fixed upon their partner's features, watching all the little expressions of pleasure which wash over them and were it any other situation he thinks he would probably be able to come just by watching his face alone.

"Hours? You would cave in first." His words are barely above a whisper, as he lets his teeth tug lightly at his friend's lip. Mostly a bluff of course, as he knows he himself couldn't keep this up for much longer. Not when each movement still leaves his mouth gasping and cock aching in such a way. But he's sure that if it came down to it, he could convince Hythlodaeus to let the charm go.
