Oh. He definetly knows what Byleth wants after that kiss. It's strange how he never pictured being intimate with anyone but save maybe Cloud and yet here he is enjoying a kiss from a stranger. Maybe it's this place or maybe he's different but when Byleth ends the kiss he finds himself leaning into that touch for more.

"I think I have a good idea now..." His voice is deeper then he intended it to come out but he doesn't care, he's pulling Byleth in for another kiss, tongue and all. His hands go up to Byleth's still wet hair, holding him close.
