Although he initially moves to protest, the tone of voice stops him. Maybe that was desirable, and he ought to concur rather than protest. Either way, he has a hand in his hair now, petting and encouraging, so he decides to moan noncommittally and let his master guess if it is protest or agreement.

Chuúdan grunts softly, letting his eyes slip back closed as he thrusts slowly into his lover. 

This interaction suggested that perhaps he had been wrong, since Chúdan had woken up and his understanding is that mortals need their sleep? He does not, however seem upset, and has in fact gone back to acting restful, so—all these thoughts are banished from his mind by a thrust that lands a little deeper in his mouth than he had expected, and after resisting the urge to bite down in surprise, he pushes forward daintily. Chúdan was thick enough to make holding his mouth far enough open somewhat difficult. Had he known it mattered, he would have manifested on this plane with a slightly larger mouth!

Well, perhaps as he gained more power here, he thought as the cock in his mouth started to leak, that could be a tweak he would make.

Chúdan sighs as he slips into an easy rhythm, gentle on the demon he sensed struggling between his legs, but steady and fast enough to have him leaking. The sran had been rather timid about sex at first, so when he’d first awoke to the fingers first exploring his shaft while he slept, he decided remaining “asleep” was the best call. Let the demon experiment a bit at his own pace.

His eyes are closed again, but… Chúdan certainly cannot be asleep, right? People who are asleep don’t actively thrust their hips to mate. Ctoślome starts playing with the organ between his own legs again, anyway. When his got like this, it seemed to demand being touched, so surely this is simply a normal part of life as a male, and he’d have been woken up to tend to it himself without someone around to do it for him.

“Mmmm, that’s it. Suckle it just like that. It’s what you wanted when you woke me up, right?”

Yeah, that confirms it. He pulls back enough to speak. “I wasn’t sure if I was supposed to attend to it once it got hard again! I didn’t mean to wake you.”

Chúdan makes a noncommittal noise in reply, guiding the demon back onto his cock

Well, that isn’t a no. He closes his eyes and plunges downward with abandon, happy to have a pleasant task in serving a superior for a change. Already this was better than his former residence.

“Mmmmf” Ctoślome is much more confident and eager this time around, and Chúdan is happy to oblige him, thrusting into his waiting mouth happily.

Indeed, the first time had primarily been an issue of novelty. This time, he knew roughly what he was getting into, and so he could skip the awkward balking at things he couldn’t eat being in his mouth and move straight to bobbing his head and closing his eyes and licking the salty skin in his mouth.

Chúdan sighs, bucking more intensely into the demons eager lips, shuddering as the srans tongue worked its way around his cock.

Enjoyable as this is, Ctoślome is still uncertain how to measure whether his performance is adequate. Certainly the man seemed to be reacting to it gamely, but how long should it be until he came again? He figured, from the fantasies he’d seen in others’ minds, that he ought to make it happen as soon as possible, and to that end he threw himself into his task, bobbing voraciously and taking full advantage of not needing to breathe.
