Xavier is an incredibly sexual person, especially with those eyes of his, right?
I want him to give Gaspard smoldering looks while he's giving other people slow, hot kisses, which makes Gaspard pause or lag while he's busy with someone else as well.
I want him to tease Gaspard though bodylanguage, which doesn't really mean he has to grope his penis idk. Like, if they're alone in a room together, I want Xavier to lie back and stretch or whatever while he's looking at Gaspard.
