ClarkDamiPrime where after first meeting him Supes calls for Prime and Prime shows up to him ballsdeep in Dami with a kind little smile going 'You made a good impression on him and he wanted to see you again' and Prime and Clark share Damian's holes. Prime is happy to be accepted, Clark is happy Prime is putting effort into his redemption, Damian is too busy cumming to think anything.
Aaaahhhhh, Clark and Damian and their regular clandestine meetings, Damian off the bat mentioning that he met Prime, but he wasn't horrible and actually seems to genuinely be seeking to better himself—only for Clark to bring it back up when he's got Damian held against his chest, back to front, fucking him slow and lazy, asking if he thinks Prime deserves a reward for his good behavior while mouthing at his shoulder. If Damian wants to see him again, slipping his hand up his chest to push three thick fingers between his lips, asking if he could take more. And of course Damian's going to agree, for as much as an eyelash fluttering groan and him clenching that much tighter around Clark's cock counts as agreement.
Prime walking in on that. Damian flushed, drooling around Clark's fingers, looking back at Prime with a half-lidded, already fucked out expression. And Clark's just. So damn pleasant about it. The guy is a menace, honestly. Prime's undressed and climbing into the bed before Clark can count to one. He's grabbing at Damian's thighs and licking the spit off his cheek, mumbling about being good having the best perks.
