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.

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."

“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
