Final Fantasy VIII, Seifer/Zell, topping from the bottom
Seifer hates it when Zell can't shut up for a moment; he speaks during classes, he chats during the breaks. His mouth is open as he's rocking on his toes ready to fight, he's goading their enemies as they train together, even though the monsters would attack without calling them dumbasses or fuckers.
Threats never worked. Slaps only work for a moment, until Zell is too shocked to shout and yell or before his fists descend to pay back. (And once the fists connect Seifer is too busy trying to breathe and the yammering of Zell becomes the least of his problems.)
That leaves shutting Zell's mouth in other ways - pushing Zell against a wall and kissing him; forcing Zell onto his knees and stuffing his mouth full of cock; or when they are in the dormitories using a gag as Seifer fucks him hard.
These ways are pleasurable and satisfying at the same time - Zell is usually quiet afterward but there is a smug glint in his eyes and a bounce in his steps despite the discomfort he must be in. Seifer suspects Zell is using his temper and he shouldn't lose it like that; but as long as he gets to fuck Zell he can't really mind it.
