Tim really, really likes it when Jason comes inside him.

Jason tilts his head and stares at the innocuous post it notes on his fridge.

The costume version of the Red Robin uniform that Cass provided Jason with has been altered to fit his proportions. The fabric is form-fitting but not uncomfortable, and the bandoliers snap across his chest without issue… except for the sordid way they frame his pecs. Between the chest action, the absence of a cup, and the feathered cape, he really feels like he's about to turn tricks. But, well… he can't complain. At least he has it better than Tim.

“Remind me why I’m the one on my knees again? I look ridiculous.” He’s not kidding. He doesn’t have the fucking physique to pull off submissive kitty cat. He’s broad, hairy, and thick with muscle. The expensive ears on his head, the detailed mitts on his hands, and the tail attached to his leather short shorts can’t possibly look anything but stupid. Not to mention the heavy black leather collar around his neck and its stupidly delicate Property of Timothy Drake-Wayne tag. He doesn’t know what the fuck Babs was thinking when she asked him to help Tim with this mission instead of Steph. Except he does, because of course their target just had to be into degrading big men. Fuck, but he hates honeypot missions.

Jason raises his eyebrows. "So we like… spar? And you'll what, let me fuck you if I win?" "Sure. If you win." Tim smiles and a thrill goes up Jason's spine. He shucks off his jacket and shoes before making his way to the mat. "It's a deal, then. Hope you won't regret it, Replacement." Tim's teeth look strangely sharp under the Cave lighting when he says, "I'll try my best."

"Hell, Pretender. Look at you being all assertive and shit. You gonna ask me to call you Daddy while you're at it?" "Depends." Tim doesn’t miss a beat. He runs his fingers lower, caressing Jason's perineum and the back of his balls with his knuckles. "Do you wanna be my good boy, Hood?" Jason sucks in a sharp breath, hips jerking as his cock pulses. "Fuck off. Of course not." "I think you do. But you're right, Daddy doesn't really fit, does it?" Tim tilts his head, remembering Jason's propensity for feminine pet names. "How about Mommy?"

“Are you alright?” Tim squints, his new ears standing at attention, “You look flushed.” Jason tears his eyes away to stare at the ceiling, “I’m fine, and you look like Beast Boy’s deleted search history.” “That’s more like it,” Tim takes another step closer and Jason steps back immediately, “but you’re still being weird.” “I’m not being weird, I’m being nice and not trash talking you. Can we get to the case?” There’s a pause, then Tim’s eyes narrow and he brushes his tail against Jason’s leg with deliberation. Jason knows he’s been made when he fails to contain the shiver of arousal that runs through him. Tim’s eyes go wide, “Holy shit. You like it.”

Jason, on a mission, gets captured. Tim, working undercover, goes to get him out. There's...a side benefit.

"Timmers sucked me pregnant," Jason blurts, and Tim watches in morbid fascination as Bruce goes through the five stages of grief in a millisecond. "I thought you said you weren't… sleeping together," Bruce says reproachfully. "He means that I, uh, impregnated him with my teeth. When I drank his blood. No sex involved," Tim explains. "It was an accident. I didn't even know I could do that."

“Why are there reporters-” Dick stopped. His eyes locked on the TV. “Oh, look at that Drake- you’re trending on social media.” Damian offered far too coolly to be any form of casual. XxX In which Tim's nudes get leaked online and he is surprisingly casual about it
