Mingjue has probably taken leave of his senses, but holding Xichen's gaze while Xichen curls his fingers around A-Yao's hips feels perhaps more intimate than he would have thought. The look on his face, however, and the embarrassment there, makes him want to reassure. Because as much as he loves that flush, he wants it there for pleasure foremost. Without looking away, Mingjue sets down everything he was carrying before finally approaching much, much closer.

"It's alright, Xichen," he murmurs, reaching out to brush gently at his jaw before he peels his eyes away to admire A-Yao's show. The angle had improved with his approach, giving him a lovely view of A-Yao's hand on his own cock.

Mingjue drops to his knees besides the pair of them and, a little strained, says, "Beautiful." Then he lifts a hand, ready to reach out—only to stop, give A-Yao a little half-smirk, and ask Xichen, "May I join you both?"
