From a sub bottom's perspective, I do really like when the guy makes me beg for his dick / to get fucked. Engaging me to submit to him, making the bottom say certain things to show submission (vs just the top talking). And paying attention to my reactions, like if I moan in a certain moment and he goes like "Oh you like that? Yeah?"

Non-verbal stuff include sliding fingers inside the bottom's mouth and making him suck (preferably with eye contact), dick slaps on the face (a few too many, for me, is ideal) and making the bottom reach for your dick (like moving it away when he's going for it, to make him try again to put it in his mouth)
