Five times Tim had a wet dream about his best friend, and one time he didn't.

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."

"Stay with me," Tim asks in a rush. "I... Bruce can't lose you again. I need to know you're alive and well." Jason scoffs. "He nearly killed me, I don't think he cares." "Doesn't matter. I think he cares, so I'm offering you a deal. Come to my place. Sleep, shower, get something to eat. Maybe stick around for longer. Just stop... Stop staring at the ground like you're thinking about jumping without a line."

"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?"

“We need you to Claim Tim.” Jason’s shirt falls to the floor as he turns around to stare at the acrobat, “What the fuck.” “Yeah.” Dick runs a hand through his hair with a manic giggle. “That’s fair.”

“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.”

Not long after his confrontation with Bruce and the Joker, Jason crosses paths with an angry Poison Ivy. She accidentally triggers his heat before leaving him for Robin to find. Still scared and angry about the incident at Titans Tower, Tim has no choice but to help Jason work through his heat when it turns out that he's been abusing suppressants and could very well die without an alpha to help.

Tim overhears a little tidbit of information about Jason that makes him wonder what it would be like to take him to bed. It doesn't take much to convince Jason to let him find out.

“Welcome to Red Hood’s Apothecary,” Jason says, coolly. “What can I do for you?” The stranger comes up to the counter, and Jason shudders. The man is short and slim, but there’s an aura of power around him that calls to Jason’s demonic nature. That can only mean one thing. Witch. And one trained by someone skilled. In fact, Jason is pretty sure that he recognizes Bruce's style all over the guy's warded clothes. Acid bubbles in his belly. His replacement has no business looking so good.

"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."

Tim knew his evening would be interesting—going undercover as a woman always is. Still, he didn’t expect ‘interesting’ to include getting fucking propositioned by Jason Todd.

Tim gives him an incredulous look. "Is this really the way you guys do things? I'm sorry, but do you really think it's okay to marry someone you barely know and create an entire person—a baby, one that's going to need someone to look after it for 18 years or longer—just for money?!" "That's not…" Jason makes a frustrated sound. "Look, you're 19, right? We can talk about the intentional baby acquisition when you're legally old enough to drink. By then we'll know if our marriage can sustain a child. But I think it's worth a try." - After civilian Tim Drake gets trapped in the Bat Cave following multiverse shenanigans, he enters an arrangement with the crime lord Red Hood in an effort to gain access to a trust fund with some very particular requirements.

All in all, their arrangement lasts for a few months. Months of filthy fucks, cutting words, and hasty walks of shame. Months without Tim letting Jason kiss him once. Months of Jason staring at the ceiling in soiled, cooling sheets after Tim's departure, gut-wrenching loneliness and self-loathing burning in his chest. Until one day, the dam breaks.

There's a pup in Jason's nest. He's here, covered in blood and guts after a long night spent, uh, clearing up some misunderstandings with the drug smugglers over at the docks, and there's a fucking strange pup conked out in his nest. Fuck his body for presenting omega, fuck omega hormones for being catnip for kids, and fuck him for being too soft to kick the brat out.
