Im a bit confused about the last panel.. who suggested what?

leo is the seme the one who suggested it. and ruca is the uke the one who didnt know he was loved

Leo suggested getting screwed? So the gal wanted them to screw? But Leo did the screwing..

leo suggested it so he can have sex with ruca. he always wanted to be the top. but the girl used pheromone perfume and tricked them cuz she thought itd be funny to see ruca do leo instead. but leo is the one who wants to do ruca which it turned out his way anyway so ╮(￣▽￣)╭

Ohhh gocha thanks

Leo wanted to screw the other guy (sorry, can’t remember names) and the girl thought it would be funny if Leo got screwed instead of doing the screwing.
Or something like that...
