Chapter Text

Klarion the Witch Boy cackled in a high pitched noise, something akin to an ear piercing fox scream.

Bruce’s jaw clenched as their group narrowed in on him, they were in his lair, drawn out by Klarion stealing some high grade magical artifacts from Zatanna. She had entrusted Batman to help return them to her while she was dealing with something off-world.

This was one of the first missions he needed all hands on deck for, magic users like Klarion could duplicate themselves and make it almost impossible to perceive who the true form was.

Nightwing, Red Hood, Red Robin and Robin. It wasn’t often at all that he would elect to bring Jason along but he’d been warming up to everyone slowly yet surely and Bruce would try his best to encourage it.

Tim however, was trying his best not to be distracted by the vigilante. More specifically his full round chest, devastatingly small waist, thick thighs...

"Red Robin. Focus on the target." Batman barked, misinterpreting his staring for being upset that Jason had tagged along by the sound of it.

Tim swallowed harshly, gripping his bo staff with a white knuckled intensity. He mowed down several Klarion duplicates, jumping over massive and small toys alike littering the floor, including a scattering of marbles that nearly wiped him out.

"This is fun and all," Klarion sounded as he was now hovered a high distance above Jason, who was suddenly held in a trance. Since he didn't wear his helmet anymore it was easy to see Jason's grimace on his face, trying to break free as his limbs twitched uselessly. Tim couldn't tell if he was in pain due to the domino mask hiding his eyes but something definitely felt more sinister than usual.

"Let him go." Nightwing ordered out in a scarily calm tone, his escrima stick crackling with cobalt blue electricity. Batman and Robin similarly ready to pounce.

Tim scanned the area around them, it was no longer thrumming with magic, it was all concentrated on Jason's body now. Hurting Klarion would likely hurt Jason as well due to how much energy he was pumping into him.

"Nightwing. Don't attack." he said simply.

"Why not?" Dick spared a glance over at him but didn't move in posture.

"It'll kill Red Hood if he's abruptly snapped out of this magical hold." Tim said, Bruce becoming entirely too still at the words.

"Oh, smart cookie." Klarion smiled, twisting his fingers and making Jason emit choked out groans as his body was pulled along like a marionette, his knees cracking to the ground with a pained grunt as his arms twisted behind his back. His head hung while he panted, clearly trying to fight the magic but unable to. "I'll reward you for the correct answer, how about that?" he said staring directly at Tim.

"Enough games." Batman snapped.

"I'll give you what you most desire." Klarion said while his eyes rolled back, racing left and right like reading a book in his mind. "You're a naughty boy, Red Robin. What a coincidence this was the one I grabbed." he laughed once more. "I'm quite fond of cats as well but not like this of course, you're a strange one."

Damian seemed to be getting agitated "What do cats have to do with anything you insolent witch?" He knew the witch boy has a cat that was currently not in sight, but??

Jason was suddenly screaming in pain which had Bruce tensing and running towards him until Dick held him back.

Tim stared in horror, what the hell was Klarion getting at?

"Did you wish he was dead again?" Damian bites out at him, which has Tim trembling slightly. Maybe at one point he wished that while deep in a haze of hatred with Jason's initial Red Hood rampage, but no... He really didn't want Jason to leave in the slightest. Quite the opposite. He wanted to keep him like a damn pet at this point, show him life could be gentle and happy for once, not constant pain and fighting...

Damn it. He was definitely playing right into this. Klarion could probably sense his thoughts.

Jason's stature was now significantly smaller, body limp and exhausted from trying to fight the extreme onset of magic, atop his head were twitching fluffy black ears with a small stripe of white on one of them, and an equally fluffy black tail wrapping around his waist in a self-soothing way.

Tim's mouth was going dry as his body started to heat up in both thrill and embarrassment.

The three others looked at Tim with bewilderment, trying to process what Tim could have possibly wished for in the recesses of his mind.

In their utter confusion is when Klarion simply said "Thank me later." with a wink in Tim's direction, poofing out of the room with ease.

Bruce recovered the fastest. "He's probably low on magical energy now. I'll finish this with Robin. Nightwing, Red Robin, help Red Hood back to the cave." he haltingly helped Jason up who had collapsed, oversized clothes now pooling on his body, breathing labored and melting into Bruce.

Anyone who had known Bruce long enough could tell he was struggling to let go. A now ungloved hand petting through Jason's curly hair and... cat ears, before checking the pulse in his neck. "Jason?" he whispered, "Say something." Bruce urged but all Jason did was softly groan, fluffy ears drooping, eyes hooded.

Jason was handed over to Dick who picked him up with a new found ease. His face seemed troubled but softened when Jason all but curled into his his hold, tail wrapping around his arm loosely.

Tim's chest felt all warm and fuzzy for a moment before a bitter jealously soured it. Maybe it was better Dick was the one holding him, he bets he'll be questioned all the way to high hell once everyone returns to the cave. It'd make it weirder if he was the one rushing to get to Jason, right?

He was still jealous.

***

Jason was sound asleep on the med bay bed with a simple IV drip, Tim had volunteered to be the one to bandage Jason up. Too intrigued to care about suspicion.

Dick had given him a really strange look but said nothing of it as he immediately went to shower and change. Whatever then, just the two of them. He had been anxiously waiting for this moment the entire trip back.

Tim hummed to himself, eyeing Jason closely.

His knees were pretty badly bruised and scraped up with small wounds and one of his arms had to be pushed back into its socket but he was mostly fine... after maybe excessively bandaging his knees just to have something to do he finally confronts the changes.

Tim pets Jason's dark hair first, unnaturally soft and feeling a lot more like fur in a way, just a little tuft of white in the front, his cute cat ears that matched his hair fluttering every time Tim ran a finger against it. He looked so... adorable.

His features were smaller and slightly more feline in appearance in a very subtle way. Tim lifted Jason's plump lip carefully to see a tiny set of fangs. The changes were small yet endlessly interesting to Tim.

He couldn't tell just how much Jason shrunk yet but he could guess, with a swooping excitement inside himself, that Jason was significantly smaller than him now. Only by three or four inches, but still. His stature was definitely way smaller and more lithe but his defined chest and thighs were as prominent as ever. Maybe more so. He was still toned with muscle, just not as pronounced.

They'd have to spar later and see how much this really impacted him.

Tim became lost in thought, still idly petting him. Slowly, memories abruptly bursted to life behind his eyelids. The feeling of guilt, resentment and the desperate need for more. Of course Tim had wished for this. He created all the conditions for this to come true.

It was a silly fantasy as first, something he read before bed. All about alphas and omegas, claiming bites, heats, slick, ruts, knots… Inseparable, needed. Omegas needed extra care. Tim ached for someone to belong to him so completely, so that maw of horrible loneliness that always clawed through his chest and iced his veins would quell just once. It was possessive and pathetic.

He couldn’t find it in himself to feel truly bad at all about what he’d done.

Jason’s long and extremely fluffy tail of black fur began to stir as he slowly awoke. If Jason was a bit more aware of himself he'd probably be embarrassed by the pitiful meow he made as he rubbed at his eyes and slowly sat up.

Tim’s thoughts still ran restlessly as he watched the other blink sluggishly. Jason was so traumatized and so alone for so long. At odds with everyone. He only ever stuck around for missions, ignoring any and all attempts made by anyone to connect again- most especially Tim. He knew Jason probably couldn’t stand him, even still. Tim had been trying hard to get Jason to notice his advances, all the compliments and intricate gifts he could get him without scaring him off even further. New gadgets, motorcycle gloves, a gag gift of hello kitty band-aids… It had all gone largely ignored. He was always so caught up in his crime lord work and feeling unwanted.

It all felt hopeless.

Until now.

Tim stiffened as he leaned back but he was barely containing his nervously bubbling laugh. "That was really cute." he says in reference to Jason’s little mewls and meows he’d been making. Still not fully awake then.

"Mm?" Jason grumbles groggily. Squirming as Tim continued to pet at his cat ears. Jason may never let him do this so freely again, he had to get his fill now.

Jason's legs trembled slightly with a struggle between a whine and a weak purr. He was only dressed in loose boxers and his own now oversized shirt. Jason was fully awake now and went completely still as he felt himself become wet, the white fabric of the boxers obviously exposing the wet spot as he came to somewhat of his senses and tried to jerk away from Tim.

Tim of course noticed. It was one of the conditions he’d made with Klarion… when he set up the contract to make Jason this way. The condition was that his memory would be wiped prior to their encounter so that Tim’s surprise would be genuine, but all that negotiating returned to his mind the moment he stepped foot in the Bat Cave. It had been a little delayed and fuzzy but… Tim could practically vibrate from excitement now. It worked. It goddamn worked.

"Holy shit." he lifted Jason's shirt up slightly to see, yes the small outline of a hardening cock, but below that being the puffy lips of a cunt, easily visible through the wet fabric. Tim doesn't know what possessed him but his fingers lightly trace over it and press into the hardening clit just below the little cocklet like he was in a trance.

Jason damn near yowls before a panicky pitchy noise replaces it. "Tim, what the fuck- what... Whats going on and what are you doing?" Jason's voice didn't hold the same timber but it was still low and bratty sounding as ever.

Tim experimentally pet Jason's ear again with a feather light touch which made Jason pant in an overwhelmed way, a new gush of slick seeping into the ruined underwear as Tim renewed his effort to press his fingers against the warm cunt, teasing his fingers against the hole as they slipped in just slightly between his folds, molten hot. The fabric being the only barrier.

Awe, he was so very sensitive. Whining from barely anything.

Tim felt his own mind frantically trying to keep himself in check while the other part wanted nothing more than to sink his mouth around Jason's new pussy and eat him out until he was completely soaked and ruined in pleasure. His noises were already so pathetically arousing, his tail swishing to try and wrap around Tim's arm.

Tim was getting entirely too carried away.

He has to pull away as Dick suddenly reappears, a bundle of clothes in his arms. Luckily Jason's shirt was big enough to cover himself for now and he seemed a little too out of it, cheeks rosy red complimenting his light dusting of freckles and puffy bottom lip bitten raw with two punctures of blood, likely from the new little fangs.

"How are you feeling Jason?" Dick drops the clothes on the bed and pets along Jason's head casually which makes the younger let out a sigh.

"I don't..." he struggles, thinking. "Weird?" Jason seems to catch a glimpse of his own tail and goes into minor shock. "What the fuck?! Is that mine?"

Dick shares a look with Tim, the 'Why didn't you tell him yet?' look, and Tim shrugs noncommittally.

"Um, well. Yes. You look very different now. We'll run some tests later but I modified some of Damian's old clothes for you. Cut holes in them, really but... It'll work for now." Dick offered.

Jason looked about two seconds away from freaking out "That witch, all that painful as fuck magic for this??" he complained crassly but it came across more whiney than anything.

Dick seemed a little entranced just watching Jason's cat ears flicker and tail thrash around frantically. When Jason tried to get up all it took was a single solid hand against his abdomen for Dick to put him back in place. Dick looked like it was getting to him.

Like it was getting to Tim.

A low heat was simmering in his stomach as he watched that perfectly tanned hand damn near encompass Jason’s waist.

Jason made a small snarling sound, pushing Dick's hand who hissed at the scratches Jason had left, his now milky colored nails in the slightest shape of claws, that retracted almost immediately into looking more like regular nails.

"Ow.." Dick said mostly humorously, smiling at Jason who was undoubtedly close to pouting. "Tim, help him to the showers and maybe explain the situation to him this time. I'll be waiting here for Bruce and Damian to debrief. Join us when you're done." he ordered.

Tim nodded absently and gave his full attention to Jason once again, taking his IV out. "I just bandaged your knees up so we'll have to be careful." Tim said, not giving the option for Jason to do it himself.

Deciding quickly just to pick Jason up and pin his arms against his own chest seemed like the best option. Jason immediately hissed and tried to bite at Tim but the kevlar of his suit likely only hurt Jason in the process. He carefully picked up the pile of clothes and held firmly onto the small ball of rage that was currently trying to tear his throat out.

"I can fucking walk- You asshole!" he argued loudly.

Tim thinks once Jason realizes how short he is now he's probably gonna throw a tantrum about it, so it may as well happen in the shower, so he didn't have to wait around for Jason to calm down.

...

Jason is glaring daggers up at him but he seems overwhelmed by how upset he is. "You wished for this?!"

Tim rolls his eyes "Not exactly, the witch just does whatever he wants, okay?" he excused, turning him around and pulling Jason back into the stream of water, massaging shampoo in his hair.

This makes Jason hiss out weakly, clearly loving the warmth of the water but it seemed he had some cat like instinct to hate water regardless. It was a little funny. "What do you mean not exactly-" Jason complains before Tim washes out the shampoo and starts on a path of washing his body. Jason squirms, "You... you were touching me earlier! You goddamn freak. Don't tell me you didn't wish for this perverted shit-" he gets cut off by Tim's harsh scoff and hand trailing against his cunt once again.

A skilled finger rolls against his puffy clit which has Jason choking on his own words and breaking on a whine with trembling legs, trying to close his thighs around Tim's hand. "I was doing some research. Investigating everything new I needed to know about." he replies, the sound of the shower suddenly becoming like a white noise to make every word intense.

Tim is relentless, a long and thin finger sinking into Jason's fiery hot core as his walls clamp around him almost instantly, unable to control how the pleasure was affecting him. "Ngh- Tim... Too much-" Jason is making shuddering whines between small mewling purrs as Tim pumps in a second finger.

"There you go, feels good, right?" Jason's weight was fully leaning against Tim now, hips rolling into the feeling as Tim angles his fingers to hit the spot that has Jason panting and beyond words. Tim massages his fingers against it, Jason letting out a broken sob as his walls flutter and try to grip onto Tim harshly. His body locks up in tremors as slick pours down his thighs, his stomach now painted in pearly cum. Eyes rolled back with a weak groan.

“I don’t… I don’t… Fuck.” Jason tried to gain a semblance of thought but it was almost impossible.

“Shh.” Tim pulls lightly at Jason's tail, it had wrapped around Tim's back just slightly and it has an almost electric reaction from the other as he cries out pathetically, a little more cum drooling from his small cock. “Don’t you feel so much better now? This is what you needed.” he whispers lowly.

“Mm…” Jason mumbles, his head rubbing back into Tim’s chest.

Tim quickly pulls his fingers out and finishes washing Jason up who had gone boneless in his hold, his own hard cock throbbing in need.

How badly he wanted to fuck into Jason who was all glassy-eyed and pliant now...

He couldn't though, not yet. Even showering together like this with Jason had once been an awkward experience and that was just quickly washing off in the cave stalls after sparing. This however... everything was so new about this. It was exhilarating.

Jason pressed into him like he wanted more, fighting between instinct and confusion. Tim was slightly worried Jason might tell on him to Dick or Bruce, but he seemed sated and quiet. Jason always handling things alone worked in Tim's favor no matter if it made his heart ache a bit for him.

"Your clothes are on the bench. Meet with the others while I finish up." he orders after a while when Jason had just been standing to the side a bit dumbly, nuzzling into the fabric of the soft towel he was given to dry off with instead as it blanketed his head. Maybe another instinct he couldn't help, purring quietly.

Tim huffs out a laugh which has Jason spooked from his trance and scrambling as he hurries to dress, groaning when he saw the cutout in his shorts and boxers for his new tail. Maybe at how small the clothes were too.

"I'm going to kill you, Tim..." he growls out, looking every bit adorable with his padded knees and matching black shirt and short combo. Tail swooshing around chaotically.

Tim snorts at his antics before leaning against the shower wall and taking himself in his hand, panting hard.

***

Tim walked in to see Dick coaxing Jason into his lap, towel drying Jason’s tail as the younger laid his wet hair against Dick’s chest, who didn’t seem to care in the slightest that his shirt was getting soaked. Jason looked like he was going to fall asleep at any second, Tim doesn’t think he’s ever seen Jason look so content and calm.

Damian was unsubtly staring at them, still in his Robin gear. Jaw clenched. Tim couldn’t tell if he was jealous or disgusted, maybe even just utterly curious. Tim himself though? Maybe slightly…. Very jealous.

Jason lets out a small huff as Dick coos at him and begins towel drying his cat ears and hair. “There you go, much better than being all dripping wet and tracking water everywhere, hm?” Dick laughs, Jason’s curls were becoming increasingly frizzier, Dick didn’t seem to know that just rubbing the towel around like he was wasn’t exactly good for his hair texture, but Jason didn’t seem to mind as he simply let it happen, noticeably drifting.

Bruce was researching about cat hybrids getting more and more unsettled when all he could find were smutty fanfics and hentai. The Bat Computer had never been so debauched. Tim felt his face begin to burn in embarrassment as he sits in the chair between Bruce, Dick and Jason.

Tim found himself staring just like Damian was as Dick was all too happy to be able to have Jason in his lap like this. “Do we really have to change you back? You’re so small and cute like this.” he teased, which had Jason tiredly swatting at him grumbling about how he’s an asshole.

Tim snorted (he agreed with Dick, obviously) before feeling the tension of the room, namely Bruce, next to him start to rise.

“Stop antagonizing him.” Bruce snapped, a gloved hand running through his drying sweat soaked hair. It looked greasy and gross, the smudged charcoal all over his eyes only adding to his exhausted look. Tim swallowed harshly as Dick paid the older man zero mind at all.

Yet the silence stretched and became heavy.

“Tim. What exactly did you wish for?” Bruce grumbled out.

***

Damian triumphantly pins Jason once again into the training mats. The hybrid bit back a growl of frustration, “Again!”

“This is the third time in a row I’ve bested you. You can’t throw the weight you don’t have anymore against me. Try harder.” Damian’s face was mostly blank but smug and almost… fond at the same time. It was all in the small twist of his lips and slight shine to his eye.

Tim had been watching Jason resort back to robin techniques seamlessly, his tail was a constant hazard… but it was almost seamless. Damian and Jason also were pretty evenly matched in their league techniques. It didn’t stop Jason from losing every time though, becoming increasingly upset. “I’m not- I’m getting the hang of it, okay?” it would usually sound gruff from big Jason, instead it sounded bratty. Or well, Tim was just finally paying more attention to his bratty behavior.

Instead of helping him up right away or responding, Damian pets him. Fond. He was definitely fond. It was something that almost instantly calmed the hybrid. Purring just a little. Damian was so good with him. “I’ll be expecting improvements, then. Otherwise you’ll stay a house cat.”

They had a whole month until Zatanna would be able to come back to earth and see if she could help Jason’s condition. In the meantime, Jason had been valiantly claiming he was fit to go back out and patrol even though he clearly wasn’t.

When they do get up, Jason is noticeably several inches smaller than the youngest. All pouty and moody from losing, cat ears twitchy in irritation. It leaves a certain satisfaction in Damian’s demeanor, a calculated protectiveness which is exactly what a prickly yet vulnerable loner like Jason needed.

“It’s my turn.” Tim says simply, Damian excusing himself with little complaint as he had homework to do anyways.

“I won’t go easy on you.” Jason says with a vicious little fanged smile.

“Oh, I hope you won’t. I’ll be trying my hardest.” Tim responds with a cold cockiness. A ruse.

It ends in a very similar manner, Jason sniffed harshly, eyes watery. Tim had to hide his face to not openly coo and tease him. “It’s not fair…” Jason complains, sufficiently pinned by Tim. The hybid came a little closer, his nose running along the underside of Tim’s jaw with huffy breaths. He looked a little lost in himself, small purrs and noises escaping his lips as he rubbed against Tim, his soft hair and cat ears now tickling his face.

Tim read that it was a submissive gesture to acknowledge another’s dominance after the second time Jason had done it, his stomach heating with want. Did Jason even really know what he was doing? A tentative lick against his neck brought Tim into action as his hips settled down between Jason’s spread legs as the hybrid gasped, suddenly broken from his trance.

His breathing became harsher. He was noticeably soaking through his training shorts.

“T.. Tim.” he coughed awkwardly. “Another round?”

“I dunno, kitty. You were getting pretty distracted.” he pretends as if he was considering leaving this position, Jason staring in anticipation- but of course he wasn’t going to. His hand moving to pet Jason in a way similar to Damian had, but they both knew it was more charged. The light touches making Jason squirm like they usually did. He only reacted this way when Tim did it and it made Tim’s horrible devotion grow only stronger because of it.

“I’m supposed to be way stronger than you.” Jason complained even as his hips twitched up desperately, nuzzling into the hand that was now cupping his face.

“Mm, are you?” Tim whispered, letting the hybrid continue to rut up against him to little satisfaction- becoming more irritated and whiney.

“Tim, get off of me.” Jason growled out, though his hips hadn’t stopped moving, his tail whipping out just slightly across the mat. His bottom lip between his teeth as it looked like it took every bit of concentration he had to be able to command Tim.

“Alright.” Tim relents easily, his own desire burning lowly as he watched the haughty omega dizzily sit up. It looked like he hadn’t expected Tim to agree so quickly.

Tim was in this for the long game though, he wouldn’t go any further until Jason came to him first, begging for him. Desperate. The hybrid had to think it was his idea to ultimately be with Tim... Despite how ridiculously blue-balled Tim was starting to feel all the time, he held firm.

“Are we gonna spar again?” Jason asks, voice thick.

“No, you can go get washed up. I’ll be up later before I leave.” Tim sighed, patrol was soon.

Something akin to disappointment flickered on Jason’s features before he nodded weakly, cat ears betraying his cool demeanor as they noticeably drooped.

Tim had to suppress a laugh. Too cute.

***

He came up from the cave to the sight of Jason’s head rested on Damian’s lap as his hair was being pet mindlessly, homework haphazardly spread on the living room table as Bruce occupied the seat on the couch beside them (despite the vast and lavish atrocity that it was, easily big enough to seat ten people). Jason’s curled up form was between the two, his socked feet against Bruce’s leg- He looked busy on his phone but he was massaging Jason’s ankle lightly. Like a tether to contentment.

Things were going better than Tim could have ever even anticipated at the manor! Everyone had adapted to Jason’s new needs so easily it was scary. A scene like this would have never been fathomable mere weeks ago.

Maybe because this is how Jason was always meant to be. Kept. Pampered. Spoiled. Not on the streets with two lifetimes of trauma bitterly fueling him, never allowing himself the softness of life in fear of it all being taken away again.

“Oracle will be on the comms, Tim. Please report to her if anything goes awry. Dick is on his way from Blüdhaven to visit but he’s open to being back up if needed.”

Tim was a bit surprised, Oracle had all but retired.

Bruce seemed to notice his inner conflict. “Both volunteered after hearing that you’re taking over crime alley for the time being. Its highly dangerous since you’re not used to it.”

“And Batman?” he raised an eyebrow.

Bruce looked at Jason for a long moment before sighing. “I’ll be patrolling soon. I can assist if needed as well. Damian will be staying here.”

Tim suppressed a smug smile as he squatted down in front of the cat hybrid and ran a thumb against his cheek. “I’ll be doing your routes now Jason, meet me in my room later and I’ll tell you how it went.”

Damian’s eyes flicked to his, as Jason was fast asleep. “He was helping with some of my english work before sleep took him.” it wasn’t often at all that Tim and Damian would have a casual conversation like this. Things between them were… awkward at best. Yet it seemed having a mutual thing to discuss between them helped a lot.

“Well, you know. Cats need a lot of sleep.” Tim supplied.

“I know.” Damian didn’t seem bothered in the slightest that his lap had become the hybrid’s pillow.

***

It became routine after that.

Tim’s hair was wind whipped and eye charcoal was still present and streaking down his face after taking off his domino mask. His body ached and his mind was weathered with the brutal realities crime alley offered.

It was soothed when he saw the cat hybrid peaking up at him from his bed- though Jason occupied it more now than Tim ever did. He immediately head butts lightly into Tim’s palm as he ruffles his hair up. Even with how awful Tim was feeling, having someone to come back to after every mission made things so much easier, like he could breathe again the moment he was greeted so warmly.

Of course it wasn’t always smooth sailing- Jason had a lot of issues with giving up his work. In a lot of ways, it was Jason’s entire life after resurrection. He endlessly coached Tim on what to do, how to do it. The right amount of aggression and punishment criminals needed for transgressions on his turf. It was really rocky. The Red Hood’s absence left a hole that Tim was truly struggling with.

Tonight wasn’t one of those nights, there were several shopping bags littering the floor, likely from Dick buying Jason a bunch of new outfits because he liked dressing the hybrid up now. It was a little outdated and millennial of course, but Jason didn’t seem to mind all that much. Always wearing whatever Dick bought him when he was around. It was really endearing… and at this rate Dick would never stop.

“Dick’s spoiling you again I see.” Tim acknowledges, simply stripping his gear off, leaving him in nothing but boxers.

“Mhm. I’ll just be glad he’s held off on all the Nightwing fan merch.” He says distractedly, trying to get impossibly closer into Tim’s space.

“He’d beat me to it, buying you the cheesy Red Robin merch…” Tim teases, finally laying down. The hybrid curls into him almost instantly.

“Eugh… you wouldn’t.” Jason huffs.

Tim raises an eyebrow with a small smile.

“No!”

Tim laughs before he divulges into every gory detail Jason may need to know about the cases Tim was taking on.

Yes, they debriefed in Tim's room, he couldn't entirely say it wasn't orchestrated that way. Tim wasn't above doing morally gray things to reach a goal which helped in doing a lot of the work Jason used to. It was better to talk about it all here, away from prying ears.

It also conveniently meant the cat hybrid shared his bed with him, not bothering to leave when he'd already been awake to meet with Tim at four am.

Tim assumed Jason seemed satisfied enough with his work, all things considered.

That.. and Jason's intense purr as he climbed on top of Tim. It was silent for a while as Tim simply held him, waiting for Jason to say what he was clearly holding in.

Over the past month or so with calculated touches and gentle manipulations, Jason had been so easy to mould into a needy little thing always coming to Tim for attention.

Sparring sessions with Jason had been increasingly charged, often ending in heavy breathing and long glances as they touched for a moment too long or getting hard while choking the other out... pinning down the hybrid for too long a time to be casual, both of them overheated with sweat and body heat, squirming for friction.

Pulling Jason close every night, securing him in a blanket of safety. Creating a room that was theirs instead of just Tim's, littered in books, weaponry and leather jackets that were now much too big for either of them. Tim's tech and nerdy figures among his old band posters. He loved how intertwined it had all become.

Tim had been holding back, only letting Jason rut against him when it got to be too much for him or playing with his ears and tail until he was dripping wet in his boxers but going no further... he wanted Jason to be the one to finally snap.

"Tim when you touched me in the shower that one time... when this all started..." Jason struggled to express what he wanted, face beet red and trying to avoid Tim's adoring gaze. "God... fuck. I feel empty okay?" he rushed out.

Jason had finally snapped.

Tim let out a shuddering breath, petting at Jason's cat ears lightly which had him squirming and jerking against Tim's sturdier body- likely getting all slick just from the small touch.

"Were you even listening at all to what I've been telling you about? I worked hard, you know." Tim then rubbed the spot under Jason's chin to get him to look up at him.

Tim wasn't a hybrid himself obviously, but he knew Jason has some sort of scent glands there now which was scenting Tim to smell like the hybrid. It had him melting into the touch, his hips stuttering against Tim. "Hm?" Tim tried, Jason's eyes going slightly glassy. "Were kitty's own fingers not satisfying enough?" he teased, Jason's face twisting in embarrassment. "Can't think about anything other than having your pussy filled?" Tim pulled Jason down to speak lowly into his ear.

A low pleading moan escapes Jason’s lips. "I was... I was listening. You just talk too much. Hah- this is your fault that it's not enough... need bigger." Jason's kneading at Tim now impatiently, tail waving around as if trying to entice Tim. His small whines overwhelming Tim's senses.

"Do you even know what you're asking me for Jason?" Tim asked now playing with the fluffy appendage. Jason grumbled something under his breath, letting his claws out to sink into Tim's chest. "Ow-"

"Stop teasing me. I want... you to fuck me." he said, purring as he encouraged Tim to pull at his tail a little more. Tim swiftly takes Jason's shorts off, shocking the other with his quickness, his body temperature running unusually hot.

He sinks two fingers into him with ease due to how wet Jason is already. Jason's mouth parting on a choked moan, squeezing around his fingers so harshly Tim feels his fingers might break. "So desperate. All wet just for me?" he grins lazily, pumping his fingers as much as he can with how hard Jason is clamping around him, breathy little sobs being muffled into Tim's neck.

"I don't know whats wrong with me," Jason whispers "Its all I can think about, want you to fuck me so bad..." his tongue laps at Tim's neck, his small fangs threatening the fragile skin and fluffy ears ticking the side of Tim's face as his lower body convulses when the younger crooks his fingers up, sending blinding shots of pleasure through the hybrid. "Hnngh... Tim.. fuck." his cocklet also being overstimulated by the friction of Tim's shirt with how harshly Tim is making Jason take his fingers, rocking him with ease.

"Fuck. Thats so hot." Tim mumbles ineloquently.

With a little maneuvering Tim is able to shuck both their clothes off, Jason seeming happy to lay against Tim's naked body heat with a purr before Tim lines up his painfully hard cock into Jason's overly wet hole, no lube needed in the slightest. The stretch is slow but all too easy.

"Ah!" Jason cries out as he's dragged down, sinking onto the cock inch by inch as his plush thighs squeeze against Tim's hips, his claws track lines down from the younger's chest to his stomach as he lets out a desperate mewl, now saddled on his cock so snugly. His breath is ragged and Tim can feel more wetness spurt around him as Jason shudders.

"I thought kitty wanted my cock, do I have to do all the work?" Tim teased as Jason glared at him.

"Stop calling me that." he snapped, pulsing around Tim's cock harshly as he did, eyes fluttering just slightly.

"Why not? It's what you are." Tim says before grabbing at Jason's hips and lifting him almost all the way up before dropping him down again. Jason let out a pitiful whine, tail whipping back and forth like it was unsure of what to do with the onset of pleasure. The sound of him coming down is incredibly lewd.

"Your fault! Its your fault!" he growled out, rocking against Tim as he tried to raise his legs and ride Tim despite the struggle it seemed to be for the hybrid, unused to having a cock inside of him like this.

Tim wasn't really sure of Jason's sexual history, he'd been tracking him for a long time and didn't find anything of note. It didn't matter, he knew for a fact he was the first one to fuck into his cunt.

A possessive part of him wanted to be the only one who would ever feel Jason around them. The other even more perverted side of himself imagines Dick or Kon taking apart Tim's new little pet and seeing just how well Tim had trained him... he'd be so stuffed full, both of them were massive. Tim started to feel extra flashes of arousal run through his body, bucking into Jason's tight heat unconsciously as the other gasped.

Those were thoughts for another time, far in the future once he'd actually trained Jason for real.

"I should take responsibility then, shouldn't I?" he hummed in response to Jason saying this was his fault. Feigning indifference.

"Yes!" Jason keened.

Tim braces himself before thrusting up into Jason harshly, which has him gasping and making the most adorable noises.

He imagined how this would be before Jason was a hybrid, how he would've never even given Tim the time of day. All awful words, avoiding Tim like the plague. Hardly ever at the manor aside from mission planning. He never stuck around, never responded to Tim's advances...

His thrusts become erratic as Jason cries out and helplessly leaks slick from his stretched cunt, tiny cock bobbing.

Jason had been considerably packing before the change, it was almost a shame. Use it or lose it, right?

He then flips them around, minding Jason's tail as Tim was high on his knees, Jason's only anchor to the bed being his shoulders as the hybrid is heaving harshly, open mouth panting from the overwhelm. Tim's calloused fingers from years of practice with his bo staff run along the sensitive little cock, the even smaller sack. It makes Jason shiver. He palms it easily, his hand curling around the head as Jason cries out harshly, Tim pumping him a few times just to watch Jason writhe. He looks so seductively debauched already and all at Tim's mercy.

"Tim? Kiss? Please..." Jason sounds so pathetic and needy… for him.

Tim craves that like nothing else.

He crashes his lips down against Jason's as his cock is thrusted as far as it can go into his heat, kissing against his newly formed womb. The elders eyes roll back slightly with a shuddery whine. The hybrid was gripping his cock so hard that Tim cursed before licking into his mouth, running his tongue along the sharp edges of his small fangs.

Jason leaves his mouth pliantly open, mewling noises and purrs alternating as his arms move to hug around Tim's neck. Tim then hooks his thumb in Jason's mouth so he's unable to close it as he starts a slow grinding rhythm into his pussy, reveling in the panicked meowing noise Jason produces, the sensations were clearly all new and oh so overwhelming. All his little moans and pants unmuffled.

It was just enough to have Jason squirming and clawing at Tim's back but too maddeningly slow to cum from, keeping him on an edge that he had no idea when he'd drop from.

"T-Himm, Fah-ster." Jason tries to say despite his mouth being held open as Tim holds him from under his waist with his other arm and starts to rock harder into the hybrid. His hair had become so messy, his ears twitching every time Tim's cock slammed all the way back in. "Hngh..."

Tim's knees were going a little numb from the position but he didn't care, Jason's legs loosely clinging around Tim's hips. He pulls back to admire Jason's cock dripping milky cum all down his ivory skin. Eyes blown wide and dark with want, trusting in Tim to take care of him.

Tim's eyes trail to the white scarred line on Jason's neck, a scar that matched his own. Completely different circumstances but... Tim couldn't help but believe in fate. They were meant to be together, Tim just had to be the one to make Jason see it.

He pulls his thumb from Jason's mouth and presses it directly against Jason's clit, rolling against the bud expertly.

Jason seizes as his orgasm crashes through him "Tim! Mmmn-" his eyes squeeze shut as his body locks up, pussy convulsing around Tim as Tim groans and starts coming as well, fucking the cum deep into Jason as the hybrid's high pitched meows of overwhelm and shaking intensity from the powerful orgasm brought Tim back to himself from the mind numbing sensations.

Tim was being aggressive still, his ears were ringing, his sole focus on fucking his cum back into the now dripping hybrid's hole.

Claimed. He was claimed now.

That didn't mean they were done though.

He carefully lays Jason down against the pillows, he's breathing harshly, tears and drool already present. "Poor little kitty, it's going to be a long night for you." Tim teases as Jason's eyes track him lazily. Still a detective despite it all. Can't beat those instincts out.

Tim's calloused pads of his fingers run along Jason's puffy nipples, neglected so far. Jason hisses as his chest arcs up, a pathetically quiet whine slips from his lips. "Tim?"

"What is it?" Tim asks before lapping his tongue over the nipple he wasn't currently squeezing between his fingers. It has Jason letting out a shuddery breath turned gasp.

"Do you only like me now because I look like this?" his voice was insecure, like he'd been meaning to ask this for a while but couldn't get himself to. Afraid of the answer.

Had Tim been misreading him? It almost sounded like he wished Tim would have liked him before all this, which of course Tim had. Obsessively so.

"Don't worry your pretty little head with those kind of thoughts." Tim assured, moving to pet Jason's mess of hair and the soft feline ears. He purred slightly in response to the affection but was worrying his bottom lip between his teeth, cutting the sensitive skin with his fangs once again. Tim wouldn't directly tell Jason he liked him before this, he liked it better that Jason was desperate for Tim’s approval.

He didn't pretend he wasn't a little fucked up. He would treat Jason very well regardless.

"Fine. I don't care just..." Jason tries with an annoyed huff.

"Just what?" Tim questions with a raised brow, his thumb still kneading the hardened bud of his nipple which was clearly distracting the other, clenching down on Tim's softened cock, eyes hazy.

"Keep doing what you were doing." he rushes out in embarrassment.

Tim lets out a laugh, kissing Jason for real this time, a gentle hot press and the slight taste of iron. Jason sighs just slightly, staring at Tim's lips still as he pulls away and opens his side table drawer unceremoniously.

Tim pulls out a few toys, a sizable plug, a vibrator, some pretty nipple clamps and a cock ring. He tosses them to the side of the bed.

Jason eyes him warily as Tim thrusts his hips into Jason again, just the thought of using these toys on Jason getting him all worked up once again.

"Hngh-" Jason takes each thrust with a tremor, shocks of overstimulation making it so much more powerful. Tim clips the nipple clamps on with ease, gold with teardrops of heavy dangling rubies, it has the hybrid groan out. The weight pulling on his sensitive buds causing his mind to drift, resorting back to purrs and mewls. "Feels weird..." he mumbles.

"Yeah? Say stop if you absolutely hate anything I do, I'll stop immediately. Otherwise this will probably be very overwhelming for you. Thats the goal." Tim said almost clinically as he rolls and tightens a cock ring around Jason's little cocklet that was already a deep shade of pink and hardening from the small stimulation.

"Okay... What are you doing...?" Jason asks, hips twitching. He claws at Tim's chest, wanting more attention. The pressure around his cock and sensitive nipples were making him needy. "Tim..."

"Shh." he lifts Jason's hips to keep the cum inside as he briefly slips his cock out and flips the hybrid around, who immediately whines at how the rubies swing at the motion, further swelling his nipples. His pussy clenches around nothing as a full body shiver runs down his spine. Arching beautifully.

Tim pets along his long fluffy tail before spreading his thighs further and immediately spearing himself back inside. "Tim! Mngh..." Tim didn't quite think it through that the hybrid would likely claw the fuck out of his sheets but when he sees the claws sinking into and dragging along the mattress he decides it's still worth it. His ears twisting every so often to listen to what Tim was doing since he couldn't easily see him at this angle.

Tim's hand ghosts along Jason's abdomen, hard earned muscle still present but softened, slightly swelled with cum and the bulk of Tim's cock as he feels its protrusion as he fucks it in and out, pressing down on the outline the head which has both him and Jason groaning lowly at the incessant pressure.

"You already look so bred full but you can take more though, can't you? Want to be full of my kits?" Tim says in a haze of his own pleasure. The thought of Jason's already sizable chest becoming fuller and heavy with milk was driving Tim more insane. It was too early to really think of kids, breeding Jason just sounded too tempting. The hybrid cries out with a weak meows and a sucked in breath.

"Want! Want... Please, please..." his hips shift back to make Tim's cock fuck into him even harder. So sweet for him, would Jason have ever been this sweet before?

Tim would give him whatever he wanted.

His pace became deep and rabid, Jason's tail tickling around his neck and chest as it runs across his skin. The rubies on Jason's chest swing back and forth with each measured thrust, glinting in the pale moonlight the rooms windows provided.

"Nnngh... Tim I can't... fuck." Jason cries out, his cock a purpling red, his claws fully sunk into the bed, panting and drooling messily. "Need..."

"What do you need, Jay?" Tim asks sweetly, running a hand down the arch of Jason's back. "Need to come?" he teases.

"Mhm... Can you take it off?" Jason asks, groaning when Tim rocks right into him once again, Jason's tail swiping across Tim's neck.

"What? The cock ring?" Tim runs his fingers against the ring lightly, making the older cry out pitchily.

"Yes! Wanna cum..."

"Mm... no. Not like that. Not yet." Tim tuts, pounding into his sloppy hole with intent.

"Tim, please..."

Tim sighs, gripping Jason's hips and chasing his own release, the hybrid was milking him with how much he clenched and thrashed between whines as Tim releases into him once more, warm cum filling the hybrid full.

Tim is breathing harshly as he rests his head against Jason's back, who is trembling fiercely.

"Not fair..." Jason sobs out.

Once Jason is flipped on his back and once again leaned against the pillows, Tim admires how ruined the hybrid had become. His full chest even more swollen and nipples almost as red as the rubies despite being pale pink. "Look at you." Tim admires, kissing his chest, tugging at the clamps every so often making the hybrid let out choked, wet gasps, writhing at the new feeling.

Jason is hyperventilating as his leg kicks out "Tim, let me come..."

"Not yet." Tim drags the thick plug from where he left it, fucking the leaking cum from Jason's cunt back into the hybrid with his fingers before easing it into him. The older groans with a short sob. The plug was thick and long enough for Jason to clench around for pleasure. He must have been feeling so empty, sucking it in so greedily.

Tim then takes the vibrator, kicking it on to a low setting as he leaned forward to kiss Jason's pliant mouth, wet from drool and bitten raw. It seemed Jason couldn't help but gnaw on his own lip. Tim licks the lingering blood off before claiming his mouth in a deep kiss, Jason sighing into it. He looked so dazed when Tim pulled back with an evil smile.

The vibrator presses against Jason's clit with no warning.

The hybrid's eyes roll back almost immediately with a soundless moan, gripping onto Tim's arms as his claws dug in.

Jason is too preoccupied to notice as Tim leaned down to suck the abused nipples into his mouth, suctioning around the jewels that it has him sobbing harshly.

"Mm! Tim- Tim..." Jason gasps.

Tim increases the vibration to the highest setting, Jason nearly screams as his body locks and convulses through an orgasm, and another... and another. All his breathy noises driving Tim insane. His clit was so puffy and engorged that it was hot to the touch, so abused. Another orgasm crashing through Jason has him crying fully. Lashes dark and vision blurry with tears. Tim still keeps it there as Jason continues to sniffle and mewl all deliciously desperate. Only able to cum with his plugged pussy and not from his purpling little cock.

Tim takes the nipple clamps off with his teeth, sucking at his chest as the hybrid produces a small spurt of milk as soon as it's released. All the stimulation had tricked the hybrid's body into overdrive.

Tim wasn't sure it would work, only trying because he saw no reason not to, but now? He would never forget this. Mentally cataloging all the clamps he would now get his sweet kitty.

He felt himself filling out to full hardness again as the sweet substance filled his mouth. Suctioning and lapping around Jason's chest to get everything he could. "Doing so good for me Jason, making milk just for me.." he says almost drunkenly.

"Agh-! Too much... Please I can't take anymore... Why is my chest…?" Jason struggled out, likely not even processing what Tim said though he arched into Tim's mouth as the hybrid sniffled and let out mewls of pleasure.

Tim took pity, easing the cock ring off as he moved to the other nipple to drink down the small amount of milk that leaked down his chest, nipping down on his bud lightly as he palmed at the plush pec. That was all it took for Jason to shake through another seizing orgasm, his little cocklet shooting copious amounts cum between them as milk spurted in Tim's mouth simultaneously, even sweeter than before.

Tim groans before he licks his lips and then admires his work.

Tim watches Jason's face, completely slack in pleasure, panting so harshly it seemed almost painful. He was so teary eyed and his cheeks were painted in such a deep blush. Jason had leaked through the plug due to how much he came, between his legs soaked in slick. Likely his tail too.

"Good boy, Jason. You took it all so well." Tim cooed, taking a wipe from his side table and cleaning the both of them up quickly before taking the limp cat hybrid into his arms.

He began purring almost immediately, rubbing his head against Tim.

"One last thing." Tim said, petting him as he guides his head down. Jason makes a confused hum before noticing Tim was achingly still hard. He arches down obediently and starts licking at the head earnestly. "Careful of the fangs." he chides as Jason doesn't do as much as flick his tail defiantly, swirling his tongue around and bobbing down just slightly. His hands fisted what he couldn't take without his fangs getting in the way. It doesn't take much to send Tim over the edge.

"There you go. Good kitty." Tim sighs as the milky liquid of his release gets lapped up obediently. Tiredness and contentment hitting him like a truck.

Jason is still licking at him until Tim pulls him up with a petulant meow in response and lays him on top of himself. The hybrid curls up high on his chest and buries his head between Tim's neck, rubbing his head against him instinctively, nosing under Tim's chin. Soft hair and fluffy ears making Tim ticklish but it seems to make the hybrid happy so he lets it happen.

Tim pulls the blanket over them both, Jason purring in a low and consistent way. They didn't need to talk about anything yet, not now at least. God knows he exhausted Jason.

He kisses at the top of his head and easily drifts into a sleep, which was entirely uncommon for him. Endless thought spirals and wirey energy kept him up for days on end sometimes. Yet that warm weight on his chest and steady purr...

It was all too easy.
