He watches Xichen with half-lidded eyes, a shudder running through him at Xichen's order. His cock gives a twitch of interest. Why had Guangyao thought, once upon a time, that he would have to be the one leading everything?

He opens his mouth obediently to take Xichen's fingers, sucking on them reverently. His tongue moves around each digit, his hands grasping at Xichen's arms. His face flushed and eyes glazed, he can't help but wonder the picture he must look.

Maybe he could etch it into his memory to draw for later too.
