For a stranger this encounter is actually kind of endearing in a way. Byleth feels and makes nice noises. The squeak before was way too cute and he hopes to figure out what caused it again. Squall's guess is the ass, so he's going to have to grab him there again. His laughter is even more charming and Squall can't help but join in on it.

"Y-Yeah...can I try something out on you?" His words come out a little raspy, still cheery but that dark look in his stormy eyes is all Byleth needs to know how aroused Squall is. He climbs over Byleth on the bed, kissing him once more before trailing those kisses down his chest and to his exposed nipples.
