Sucking cocks

If it’s a dick that I really find attractive, attached to a guy who knows what he’s doing in that department (grooming, diet for the sake of cum taste, etc), I want to suck it for hours. Even longer if it’s a guy who’s vocal and shows the pleasure he’s receiving through squirms and moans and shudders.
Basically, if his cum doesn’t taste gross and if he doesn’t just sit there breathing hard, I’m much more excited to go down. A man who shows reactions is the sexiest man ever, in my books. God, it’s been too long.
