Distracted as he watches them kiss, Mingjue lets his fingers stroke in and out of A-Yao on autopilot, his fingers caressing and preparing...

Right. Right. Preparing.

A-Yao's more and please remind him what he was about.

"You sure? You ready?" Mingjue asks, giving Xichen a mischievous quirk of his lips over A-Yao's head. He's teasing, of course. A-Yao sounds desperate and Mingjue did interrupt, but a curl of something in him needs to check even as he uses his grip on A-Yao's belly and one hand on his own cock to line himself off.

Once lined up, though, he stops just before he's about to push in.
