Should they keep this up, Sizhui's likely to fall in love with the way Itto reacts to having his horns touched. He meets the oni's gaze full-on while stroking, lips faintly quirked again, conveying his amusement at having such an easy form of control, and entirely unbeknownst to him that Itto's considering what he'd look like having horns. (Do antlers count? They're different, sure, but he definitely has those sometimes when the timing is just right.)

His own eyes have gone a bit wide too, pupils blown out with pleasure, tongue-tip darting over his lips the closer Itto comes to his dick— but he squeezes them shut whenever Itto suddenly falls against his chest during rearranging. A soft oof escapes, followed shortly thereafter by a giggle, his hand raising from Itto's to card through his hair. He inhales sharply once that hand moves along his length though, hips jerking instinctively, which he'll do his best to reel in before Itto starts using his mouth. Currently, he can't tear his gaze away from the other man, head nodding in understanding.

“Don't worry, I will do so.” He's never been voiceless about things that bother him, after all, and this situation won't be an exception. The moment Itto's tongue winds around his cock, however, there's no protesting on Sizhui's end. In fact, it's the opposite, with his head lolling back and a shaky moan passing his lips at the warm sensation.
