For Xue Yang, a show of affection or tenderness is unfamiliar and thrilling; a little terrifying if he thinks about it too much. When it comes from Mukuro, it turns him on without regards to reason or decency. He's rock hard between them as he watches his partner suck on his fingers, eyes trained on the way his lips look wrapped around the digits. He's distracted by it, obscenely pressing those two fingers in and out of his mouth in a suggestive motion, watching as his saliva shines on them. It has him parting his lips for a greater breath, panting.

"You look too good like this." He murmurs, brows knitting together in arousal and near frustration. He prods around inside his mouth a bit longer, exploring what he can, noting the softness of the inside of his cheeks and his plush tongue before he's withdrawing them. "Good boy." He mumbles as he reaches behind him again, not wasting a precious second before he's smearing spit around and pressing one finger into him first. His eyes are trained on Mukuro's expression, not willing to miss a single second of it.
