It starts with Tim. Which…if you’d told Jason that a year ago, he’d have laughed in your face. Of course, if you’d told Jason that any of this would be happening a year ago, he would have laughed himself straight back into catatonia. And yet, here he is, creeping into the manor at five in the morning to pick up the frozen meals Alfred had prepared for his upcoming heat.

Before he’d sort-of-maybe-reconciled with the bats, Jason had handled his heats entirely on his own. He still does, for the most part. He certainly doesn’t nest with any of the pack. But he’s happy to take Alfred’s help if it means he doesn’t have to prep his own meals for the week. He likes cooking, but there’s something about Alfred’s cooking that’s just a hundred times better. Especially when he’s alone and in heat and craving something familiar.

Still, he doesn’t want to end up running into any of the pack while he’s in preheat. Most of them are insufferable enough on a normal day. Dealing with any alpha while he’s close to heat is not something Jason likes doing.

So it’s an uncomfortable shock to sneak into the kitchen when everyone else is supposed to be asleep and find Tim Drake sitting at the counter.

Of course, Tim startles the moment Jason appears in the doorway, because Jason couldn’t just escape without the young alpha noticing him and come back another day. He should have smelled Tim before he’d even entered the room, but being in the manor, where the scents of his pack are so ingrained, always throws him off.

“Jason?” Tim asks, in a hoarse voice, blinking at him in the dim light. None of the overheads are on - probably because it’s five in the morning - but the strip of lights along the breakfast bar is casting an odd, sickly wash across the alpha’s face. The fluorescent glow from his laptop isn’t helping matters either. It makes his already pale face look grey, darkening the bags under his eyes and the shadows in the hollows beneath his cheekbones.

Jason feels an uncomfortable wrench in his chest. Tim looks terrible. And normally, Jason wouldn’t care, but so close to heat, he can’t ignore the omega instincts begging him to take care of a sickly packmate.

“What are you doing up?” Jason finds himself asking, before he can think better of it. And, shit, the words come out with an odd, parental edge. It’s the same tone Alfred would use on Jason whenever he was up too late on a school night. Or on Bruce, if he was trying to get out of bed whilst injured.

Tim blinks at him again. “What are you doing here,” he asks, in retaliation.

Jason doesn’t need to answer. He should just turn around and get straight back out of here. But Tim looks so fragile in the huge manor kitchen, hunched over his computer, all alone in the dark.

“I came to pick some stuff up,” Jason says, casually. He steps a little further into the room - because if he hasn’t left yet, he might as well get his frozen meals while he’s here - and tries to ignore the way Tim sniffs at the air.

Jason has blockers on, because you’d have to be fucking stupid to go anywhere in Gotham without them, smelling of preheat, so it’s not like Tim is going to learn anything.

“And I think I asked you a question first,” he adds.

Tim turns back to his laptop and stares blankly at it, as if he’s forgotten what he was doing. He doesn’t have any blockers on and Jason can smell the almost stale scent of exhaustion in the air.

“Working,” Tim says, eventually.

“On something important?”

“All my work’s important,” Tim huffs.

Jason moves closer. Close enough that Tim stiffens at the proximity. He leans down and sniffs Tim, slow and deliberate.

The scent of exhausted alpha fills his nose. It’s strong enough to almost make Jason recoil. Omega instincts surge under his skin. His chest aches in an uncomfortably familiar way, both beneath his ribs, and where his breasts are already swelling, filling with milk in preparation for his heat.

“How long have you been awake?” he asks, exasperated.

Tim shrugs, stiff beneath Jason’s attention. “I don’t see why it matters to -”

Jason cuts him off by reaching over and pushing the laptop shut. “It matters to me because it clearly doesn’t matter to you. Get up, you’re going to sleep.”

Tim doesn’t immediately get up. “You’re seriously trying to send me to bed like I’m a pup?”

You are a pup, Jason wants to say, even though that isn’t actually true. His instincts are telling him it is though - that Tim is a pup who needs his help, who needs his omega.

“Trying to,” he says dryly, instead.

Tim tries to open the laptop again. Jason presses his hand over Tim’s, keeping it shut.

“Go away,” Tim snaps, “you shouldn’t even be here. You’re not part of this pack.”

Jason jolts, stung. Normally a comment like that wouldn’t hurt him so much, but on the edge of his heat, it feels like a blade. Tim must realise that he’s gone too far, because he immediately blanches and starts stuttering apologies. Jason swallows against a thick throat.

“I’m going to forgive you for that,” he says, sharply, “because sleep deprivation can make you say stupid things. But you’re going to make it up to me by actually getting some sleep.”

“I can’t,” Tim says. “If I - I could lie down, but I wouldn’t be able to sleep. I’m too wired.”

Jason eyes him, consideringly. The dark shadows under his eyes look like bruises, but there’s a jitteriness to him. Something strung tight.

He needs an omega’s comfort, Jason’s instincts croon. He needs a dam to soothe him to sleep.

Jason forces those instincts down, ignoring the aching fullness of his breasts. Tim certainly isn’t his pup. He isn’t even a pup. He’s a big enough boy to handle himself.

Still, Jason can’t suppress his instincts enough to just walk away.

“Well, working isn’t helping,” Jason says, archly. “You at least need to relax.”

Tim stares at the shut laptop with a petulant expression. His hand is cool and dry beneath Jason’s, nimble fingers splayed flat beneath the weight of the omega’s palm.

“Why don’t we watch a movie? You can switch off without having to actually sleep.”

Something in Tim’s scent shifts then. He glances up at Jason and the petulant expression is totally gone, something small and almost vulnerable in its place. “Don’t you have somewhere to be?”

“Nah,” Jason says easily, although he really should be taking the frozen meals and getting back to his safehouse. His heat has barely started, but the longer he leaves it, the more dangerous it will be to get across Gotham. He doesn’t really have the time to spare to be coddling Tim.

But it’s for exactly that reason that he can’t walk away. Any omega that could leave a packmate in distress while in preheat, is a stronger omega than Jason.

Tim follows him meekly to the cinema room. When Jason had first joined the pack, he’d been both disgusted and awed by the fact that Wayne Manor even had a cinema room, let alone the amount it must have cost to fit the whole thing out. A huge, squishy couch takes up most of one side of the room. Or, couch is the wrong word really, because it’s more of a nest - piles of cushions and blankets covering a surface so wide that it might as well be a bed. A huge screen takes up almost the entirety of one wall. The rest of the room is littered with bean bags and squashy chairs.

Jason swipes the remote, strips off his jacket, then drops heavily onto a pile of pillows. When Tim just hovers, Jason reaches out and snags his wrist, tugging him down to join him. Tim yelps, but he lets Jason tuck him into his side, wrangling one of the blankets out from beneath them so he can lay it across their laps instead.

“Any preference?” Jason asks. One of his arms has ended up slung around Tim’s shoulders, the younger alpha’s head resting against Jason’s broad shoulders. He can feel Tim shake his head without looking at him.

Jason shrugs, bringing up Netflix and flicking through to something easy. A Disney movie that he knows they’ve all seen a hundred times. After a moment's hesitation, he reaches up and peels his scent blockers off, letting the warm, honey scent of his preheat flood the space between them. Tim tenses, then gradually relaxes.

Jason feels himself relax in response. Smells the way his scent deepens, thick and almost syrupy. As the movie wears on, Tim’s scent starts to change too, losing the sharp, stale edge of exhaustion, softening into something smoother and sweeter. Something rich and milky fills the air.

It’s only when Tim’s head shifts, drooping off of Jason’s shoulder towards his chest, that Jason realises the last scent is him. Without his jacket on, Tim’s face slides right over his breasts, over the wet patch gathering there. The pressure against his swollen chest sends another small trickle of milk leaking out of his nipple. Tim makes a soft sound, rubbing his cheek over Jason, like a pup begging to be nursed.

Jason freezes. The arm not still slung over Tim’s shoulders comes up automatically to cup the alpha’s head, cradling him against his chest. Tim makes another soft noise at that, relaxing further into Jason’s grip.

“Tim?” Jason questions, softly. “Is this what you need?”

Tim hums. Something warm and wet touches the thin cotton covering Jason’s nipple - Tim’s tongue flickering out to taste his milk. He feels soft and relaxed in Jason’s arms, dopey with sleep-deprivation and the scent of Jason’s heat. It makes him seem younger than he is - a pup rather than the adult he actually is.

A surge of maternal protectiveness swells in Jason’s chest. If he’d thought his omega instincts were bad before, it was nothing compared to how he feels now, with a warm mouth against his nipple and milk heavy in his breasts.

“Okay,” Jason says, gently. His chest feels tight. His stomach feels oddly warm. He shifts, careful not to dislodge Tim. “Okay, puppy, it’s okay. I know how to get you to sleep. Just let me - let me get more comfortable.”

He keeps a careful hold on Tim’s head, making sure not to jolt him, or twist his neck into an unnatural position, as he shuffles around on the pillows until he’s mostly reclined, his upper body propped up and Tim stretched out in the v of his legs. Tim is still awake, but his eyes are heavy lidded and he makes no protest as Jason adjusts him, cradling his head carefully in one arm and titling him until his mouth is in the right position to nurse.

When Jason tugs his shirt up to bear his breasts, Tim’s eyelashes flutter. His soft, pink mouth opens and his tongue flickers out, lapping at a bead of milk trembling at the tip of Jason’s nipple. Jason’s whole breast tingles at the contact and his stomach swoops. When Tim opens his mouth a little wider and actually latches on, sucking hard, Jason’s own eyelashes flutter, his head tipping back and a soft, pleasured moan escaping him.

God it feels good. Not just in the physical sense, although it certainly feels amazing to have Tim’s mouth on him - a sharp electric jolt right through to his cunt - but in a deeper way. Jason’s inner omega has been badly neglected, he can admit, forced to go through heats alone, bereft of the comfort of his packmates. Having one of them in his arms, nursing, being comforted by Jason’s presence, whilst he’s on the edge of his heat, is everything his inner omega has been begging for.

He sighs and lets himself relax further into the pillows, as Tim adjusts himself a little before starting to nurse in earnest. Jason’s milk comes thick and fast, filling Tim’s mouth in thick, greedy sucks. Tim grunts. He nuzzles closer, his lips pressed hard against Jason’s skin, his nose dimpling the soft flesh of Jason’s breast. Jason can feel his warm puffs of breath against his sensitive skin. He laces his fingers through Tim’s silky hair, holding him closer, encouraging him to take as much milk as he needs.

Tim’s other hand comes up and squeezes at the breast he’s not nursing from. Jason groans. Shudders. Feels milk leak out against Tim’s palm. Those thin, slender fingers roll over the tip of Jason’s nipple, at the same time Tim’s tongue strokes over the nub in his mouth as he sucks hard and Jason’s hips buck automatically. With Tim lying between his legs, the movement rubs him up against Tim’s pelvis and the hard bulge there.

Fuck, Tim’s hard. Tim’s lying between his legs, sucking greedily at his tit, and he’s hard. A wave of arousal so strong it leaves him dizzy rushes through Jason. Slick leaks out of his aching pussy. He clutches Tim so hard he must be hurting him. His face feels hot and everywhere they’re touching feels electrified.

“That’s right,” he gasps, rocking up again, grinding his pussy against the thick bulge in Tim’s pants. “That’s right puppy, drink as much as you need. Let mommy look after you.”

The words come out without Jason meaning them to, a thoughtless babble, but Tim groans like Jason has hit him, and sucks so hard on Jason’s tit that he cries out, and Jason’s pussy clenches at the knowledge that this is good for Tim. That Jason is turning him on. That he’s enjoying himself.

Frantic with sudden need, Jason fumbles at his pants, wrenching them as far down as he can with Tim still lying between his legs, and struggling to kick them off. Then he goes for Tim’s pants too, baring the alpha to the warm air. The scents of both of their arousal floods the room and Jason breathes deep, his mouth open to catch the taste of Tim’s musk on his tongue. Tim makes soft noises against his chest, but doesn’t pull away.

“Good boy,” Jason croons, gentling his movements now he’s divested them of the barrier between them. This is meant to be about getting Tim to relax after all. “That’s right, baby, keep going. That’s perfect, you’re making mama feel so good.”

His pussy is so slick between his legs. Tim’s cock is hot and throbbing, pressed up against Jason’s thigh. Jason shifts, making sure Tim stays attached to his tit, but manoeuvring them so that Tim’s cock juts up against his cunt, instead, the slick head rubbing against Jason’s clit.

Jason trembles. Arousal shoots through him, sharp and aching. He reaches between them to help guide Tim, bucking down against him, until Tim’s cock slips into him.

“Fuck,” Jason gasps. “That’s right. That’s right puppy, just like that.”

Tim makes a soft sound of pleasure. His fingers are tight against Jason’s breast, squeezing to the point of pain. He ruts his hips, forcing his way into Jason in jerky little movements, never pulling back far enough to thrust properly. Jason rolls his own hips, trying to help him set a rhythm, gasping and panting, dizzy with arousal and the smell of their sex.

Tim fucks him just like that, his weight pressing Jason into the cushions, his mouth clamped hard around Jason’s tit. Jason groans, his hands clench tight in Tim’s hair, holding him close. He can’t stop making gasping little noises, desperate little groans and croons meant for an omega’s pup. His legs tremble around Tim, still wrapped over his hips, holding him close.

Until, suddenly, Tim’s rhythm changes. He sucks hard, making these aroused little grunting noises that set Jason aflame, swallowing heavily, gasping against Jason’s breast. His hips speed, rabbiting in and out of Jason’s cunt. Jason’s back arches, his pussy aching, full in all the best ways, so slick that Tim slips in and out of him with ease. There’s a delicious thickness at the base of Tim’s dick - the swell of his knot. Jason throws his head back against the couch cushions, pushing down against Tim, trying to encourage that perfect bulge to pop into his pussy.

“That’s right puppy,” he croons. He can feel the tingle of his milk still gushing into Tim’s mouth. The wet slide of their bodies against each other. “Knot mommy’s pussy. So - so fucking good. Oh fffuck.”

Tim knots with a sharp, animalistic growl. His teeth sink deep into the soft flesh of Jason’s nipple, sparking pain all the way up his spine. His knot blows wide. And it’s so good. Jason cums with his own startled cry, his back arching, his pussy clenching so tight around Tim that he’s sure they’ll never be able to separate.

His orgasm rolls through him in sharp, hot pulses. He can feel Tim continuing to thrust shallowly, grinding himself into Jason even though there’s nowhere for him to go. Hot cum floods Jason’s already soaking pussy in thick, wet, spurts. He can feel the alpha’s cock twitching, throbbing inside him as he fills Jason up.

Eventually, the pleasure eases a little bit. So does the pressure of Tim’s mouth. When Jason relaxes back into the cushions with a soft sigh, Tim goes lax too. He doesn’t stop nursing, but his mouth goes soft against Jason’s tit. Jason cards his fingers through fine, silky hair.

“Good boy,” he murmurs.

Tim rumbles deep in his chest and the vibration of it settles something in Jason too. Without realising it, he starts to purr. Tim’s eyelashes flutter. A few moments later, Jason hears his breathing even out as he drifts off to sleep.

With Tim warm against him and inside him, and the worst of his preheat sated, it isn’t long before Jason joins him.

Sometime later, Jason wakes to the feel of something thick rocking back and forth inside the tight clench of his pussy.

Tim’s knot.

It’s half-inflated, or perhaps deflated, because Jason doesn’t know how long they’ve been asleep. Doesn’t know if Tim is trying to pull it out or shove it in. His pussy feels stretched and pleasantly used, but that might just be from their earlier fucking.

Tim whimpers and Jason glances down at him. His eyes are shut, long, thick lashes shadowing his cheeks. His soft, pink mouth is open, resting against Jason’s breast. A little trickle of milk has dribbled over his chin.

As Jason watches, Tim’s brows furrow, his lips purse and he turns a little, snuffling around Jason’s breast as if he’s searching for something. His hips are still rocking, shallow little thrusts that make Jason want to roll him over and ride him hard.

“Mama?” Tim whimpers, nuzzling at Jason’s tit like a milk-hungry pup.

Jason reaches up and strokes gently over his face. He slips two fingers into Tim’s mouth. The alpha suckles at them for a moment before Jason tugs them free. Then with soft hands he redirects Tim to the breast he hadn’t already been nursing from.

Tim latches on and starts sucking contentedly. His thrusts quicken, although he still seems to be asleep. Jason arches. Clenches. And Tim cums with a soft grunt. He must have been fucking Jason in his sleep for a little while before Jason had woken up.

Jason clenches again around Tim’s knot. Shuffles a little to get comfortable. Then he settles back for a full night of deep, satisfied, sleep.
