Chapter Text
Jason woke up in a warm, comfortable nest, his head spinning. The last thing he remembered was Batman’s arm tightening around his throat—then a needle prick. As he rolled over in the soft fabrics, the scent of alpha pheromones washed over him, seeping from the surface of his skin down into his deep muscles. His omega instincts told him this was a safe place, under the protection of an alpha pack leader.
But reason snapped him out of that dreamlike haze. Jason quickly sat up, realizing all his gear and weapons had been stripped away, and the suppressant patches on his nape and wrists were gone. Where was he? Some kind of safehouse?
“Jason.” Batman was sitting at the side of the bed. He had removed his cowl, revealing Bruce Wayne’s face. His eyes were wide, voice raw as if scraped over with sandpaper. “You’re… an omega.”
Long before coming back to Gotham, Jason had imagined the moment when his carefully constructed alpha persona might be exposed. Anger, shock, disappointment—those were reactions he expected. What he never expected was the pain and regret he saw in Bruce’s eyes. Bruce looked… fragile. Like he could be knocked down by the smallest push.
Sure, there had been a time when Jason wanted nothing more than to knock Bruce down—but that interest had long faded. This was too strange. Bruce wasn’t supposed to be like this. He should be furious, throwing all the authority of an alpha leader in Jason’s face. Jason was always ready for that fight—capable, confident, unstoppable—unless… he was an omega.
Ah. There was the answer. As an omega, he didn’t even qualify to be taken seriously as an opponent—just a pitiful, broken doll. The thought made Jason burn with anger.
“This doesn’t change anything,” he said flatly.
“It changes everything,” Bruce murmured. “I just want you… safe.”
“You yanked me off a speeding motorcycle.”
Bruce flinched. “I didn’t know… I’m sorry. Jay. I promise I’ll never hurt you again. Come back to the pack, okay? You don’t have to hide who you are anymore, or live in fear. I’ll take care of you.”
This was… the first time since Jason’s resurrection that Bruce had formally invited him into the pack. Jason narrowed his eyes, searching Bruce’s face for any sign of deceit. But Bruce held his gaze, his expression seemingly sincere—just like the first time Jason had stepped into Wayne Manor. Omega instincts urged him to purr in appeasement, while his intuition screamed that this could not be real.
“I don’t care what game you’re playing. I’m leaving.” Jason ground out the words, crawling out of the soft nest—only for his legs to give way. He toppled from the bed, and Bruce caught him instantly, pulling the omega into his arms.
“The hell did you do?!” Jason’s instincts blared warning signals. He squirmed, trying to wrench free, but Bruce was too close—his alpha pheromones brushing against the glands in Jason’s neck, making him shiver involuntarily.
Bruce ignored the omega’s weak struggles, gently settling him back into the nest’s blankets. “I just built you a nest, Jason. You’ve been overdosing on suppressants for a long time. The second I tore off your patch, your body started going into heat. I can’t let you run around outside—going out in this state would be extremely dangerous.”
Jason glared at the controlling alpha. “Then let me put the patch back on! I can function just fine.”
Bruce shook his head. “I can’t watch you destroy yourself, Jaylad. Omegas who take suppressants long-term need to go through at least one natural heat a year. And you’ve… been suppressing it constantly.”
“What, you want me to just find some random alpha on the street to knot me?” Jason sneered.
“No!” The alpha growl rumbled in Bruce’s throat before he caught himself, stepping back. “I just want… someone to be with you through this. You don’t have to bear it alone.” He picked up a bottle of water from the table and held it out. “At least stay here for a few hours, okay? I’ll take care of you.”
Jason eyed the bottle with suspicion. An omega in heat, and an alpha suddenly showing kindness? Life on the streets had taught him to be wary of any aid offered by an alpha. Bruce seemed to understand, twisted the cap open, took a swig himself, and handed it back. Only after watching Bruce drink without any reaction did Jason cautiously take a sip.
That seemed to encourage the alpha greatly. Bruce turned, opened the small fridge on the floor, and asked, “Which flavor do you want? Strawberry or blueberry?”
The fridge was packed with pouch-packaged jelly—new from WayneTech, designed to quickly replenish nutrients and water while reducing mess. Jason had heard Dick and Tim argue over which flavor was better, but had never tried them himself—after all, he’d never really been part of the pack. Why was Bruce asking? Was this his way of extending a pack invitation? With food? Just like Batman had done the first time they met, taking Jason out for burgers?
Bruce should know Jason had always had trouble refusing anything that could fill his stomach and ease that constant, twisting hunger.
“…Strawberry,” Jason murmured.
Bruce handed over the red-packaged jelly. The cold touch soothed the fever of his heat. He twisted the cap and drank; instead of the industrial artificial taste he expected, it was gentler, sweeter. Jason began to understand why Tim called it his favorite post-patrol snack. The pouch wasn’t big—Jason finished it quickly.
Bruce, meanwhile, just stood there, watching him swallow. Sharing a room with a strong alpha during heat probably wasn’t a good idea—especially one making no attempt to mask his pheromones. Jason instinctively curled deeper into the blankets to put distance between them, but the nest was already saturated with alpha scent.
Bruce lingered at the edge of the nest and asked softly, “Jason… can I come in?”
An alpha pack leader asking an omega’s permission to enter his nest—this only ever happened with pack omegas. Jason felt dizzy. When had he become a pack omega? Why was Bruce being so good to him? This was strange. Everything about this was strange.
Bruce studied his reaction, speaking slowly. “It’s all right. If you’d rather… I can leave.”
Right now, Jason knew he should be taking a suppressant, leaving this nest an alpha had built, and keeping everyone at a distance. He had just eaten, yet the hunger coiled deep in his gut still burned at the back of his tongue, urging him to say something that went against all reason.
“Stay.”
Given permission, the alpha moved quickly into the nest. He unfastened the cape from his shoulders, wrapping Jason in his pheromones. The leather scent was unforgettable, the fireproof, waterproof cape weighing heavily over him—a sensation Jason had been attached to since his Robin days. Though his build now nearly matched Bruce’s, being held in those arms made him feel small again, like a pup tucked beneath the cape for safety.
“I’ll take good care of you, Jaylad,” the alpha murmured, pressing a kiss to his forehead.
Jason’s omega instincts answered before his reason could catch up. A soft purr rose from his chest as he pressed his face against Bruce’s neck, breathing in the alpha’s scent. Slippery fluid seeped out from between his legs, wetting the blanket. Heat flushed through him, muddling his thoughts, and the solid lines of the Batsuit took on an almost magnetic allure. Tilting his head, he caught Bruce’s lips in a kiss, the spark between them racing over his skin and blurring his vision. “B… Bruce…” he choked out.
Bruce answered with a low, affectionate rumble, one hand cupping the back of Jason’s neck, thumb grazing over the gland there to let his pheromones spread more thickly into the air. His other arm slipped around Jason’s waist, guiding him closer. “You’re doing so well. Good boy deserves a reward.”The large hand wearing the bat gloves slid down the spine, lingered on the buttocks for a few seconds, kneading them, then slipped into the folds.
Jason could barely contain his screams as the smooth texture rubbed against his vagina, feeling too good to resist. He couldn’t help but sway his hips, chasing after his own reward. Bruce’s fingers were circling around the clitoris. Fluid was gushing out of the vagina in waves, soaking the glove completely. The alpha tentatively inserted a knuckle, which was immediately sucked tightly by the flesh walls, causing the omega to moan even louder. He was captivated by Jason’s expression of ecstasy, his blue-green eyes misted over, his mouth open, exhaling a sweet citrus scent, as adorable as a pup.
The finger gradually penetrated deeper into the opening, probing in different directions, until the omega trembled and stiffened like an electric shock. Then he applied pressure on the sensitive spot, causing fluids to flow out. Jason nearly collapsed onto the alpha's shoulder, submitting to the kiss, exchanging pheromone scents, and swallowing each other's scorching moans.
The orgasm came swiftly, the pussy clenching tightly around his fingers. Jason screamed incoherently, “More” and “Stop,” until only chaotic, muffled whimpers remained. Bruce rubbed the clitoris with his thumb, intentionally prolonging the omega's orgasm, holding down the bouncing hips to prevent him from escaping.
Fluid sprayed from his palm, like an endless spring. After the omega had calmed his breathing, Bruce withdrew his fingers, but the glove was caught between the folds, hanging between his legs, creating a beautiful sight.
Jason lay back on the cape, satisfied yet dazed, tilting his head to bury his nose between the fabric, savoring the alpha pheromones, oblivious to the chaotic scene beneath him.He felt something being slowly withdrawn, and a sense of emptiness once again filled his abdomen. Bruce slipped his fingers, coated in fluids, into the omega’s soft mouth, watching as he lowered his eyes and sucked them clean with a devout expression. A burning sensation gathered in his lower body.
He leaned down to kiss Jason's shoulder and neck, caressing his soft chest. Bruce’s voice was warm against his skin. “Jaylad, you’ve done so well. My precious… my perfect omega.”
Alpha's voice vibrated in his chest. Jason could feel the bond being reestablished, connecting the two of them in an invisible way. Bruce’s touch softened, fingers threading through his curls, thumb brushing the curve of his ear as though the two of them hadn’t been trying to tear each other apart only hours earlier. Jason noticed briefly that Bruce’s right hand still appeared metal even after the glove was gone, but his mind was too hazy to linger on the detail.
Jason was pulled beneath Bruce, his legs spread apart, the heavy weight pressing against the pulsating opening. Jason's heartbeat accelerated involuntarily, thinking that all of this was about to become reality, like something dreamt.
“Alpha…” Jason’s voice was nearly a plea. “Knot me. Please.”
Bruce’s breathing grew heavier, the air thickening with the scent of alpha pheromones. He caught Jason’s hand, lacing their fingers together, and lowered his lips to press a kiss against his knuckles. “I would do anything for you.”
The thick penis forced its way into the well-lubricated slit, filling the walls with a searing sensation. Omega let out a sound nearly choking him, as pleasure washed over his nerves like a flood.Jason couldn’t remember the last time he’d been this close to Bruce.
Too many things had stood between them—differences in their understanding of justice, their stance on lethal force, their views on their kind. But Gotham always had its own gravity, and Bruce also had the gravity. No matter how far Jason ran, he always found himself drawn back into that same orbit, always thinking of the city glittering with lights, always remembering the pounding in his chest.
Sometimes he thought Bruce knew this—that was why he kept letting Jason rejoin the pack, only for them to split apart again and again.
And now, Jason had finally become part of the pack. Bruce’s sapphire eyes fixed on him, low voice murmuring his name as he thrust into him. The fullness inside him kept building, so good it made him feel like he could melt into nothing. The alpha’s teeth sank into the gland at the nape of his neck, tongue sweeping over it again and again, skin-to-skin sparking like current. Jason pressed his lips closer, leaving kiss marks over the alpha’s scarred chest.
After only a few thrusts, he entered his second round of orgasm, his inner walls spasming and squirting fluid, clamping down on the penis so it couldn't move.
The alpha let out a growl—not the warning tone Jason often heard, but one of satisfaction and pleasure. He kissed the omega’s sweat-damp forehead, his voice almost indulgent: “So sensitive, Jay. You’ve wanted it for so long, haven’t you?”
The scent of pheromones was so strong Jason’s teeth were chattering. He nodded erratically, answering the unquestionable voice of the pack’s leader. Bruce lifted the pliant omega into his arms, supporting his waist to settle him onto his lap. He pushed in to the deepest point, reaching the tender inner chamber.
Jason felt completely filled. His heartbeat pounded so hard it felt like it would burst his eardrums. He couldn’t even hear the sound of his own scream. It was as if his brain had melted, the urge to release again overwhelming everything else. “Please, B! Please, please, Daddy!” he sobbed.
The alpha gently kissed away the tears at the corner of his eyes, cupping his dazed face with both hands. With a hint of a smile, he asked, “What do you want, omega?”
“P-please… please give me your knot…” he nearly bit his own tongue from the jolts of pleasure, “Fill up my belly.”
“Of course, baby. And then you’ll be carrying a whole litter of pups, won’t you?”
Jason answered with a scream instead of words. He could feel Bruce’s thrusts growing faster, driving deeper, the urge to release becoming more and more insistent. Panic welled up as an unfamiliar pressure built, and he twisted his body, trying to get away from the sensation—only for Bruce to catch his arm.
“B… I think… I need to go to the bathroom…” he said softly.
Bruce just held him in place, pressing his nose to the side of his neck in reassurance. “It’s alright, Jay. For an omega in heat, feeling like you need to relieve yourself after being overstimulated is perfectly normal. You can do it right here.”
Jason shook his head desperately, whimpering as he tried to pull free. “I don’t… want to make a mess in the nest…”
“Oh, Jaylad. Don’t worry about that.” The alpha kissed him tenderly. “You’re lying on my cape, I can clean it up quickly. You’re home now, and I’m going to take good care of you.”
“But…but…um…” The sensation of the penis constantly rubbing against sensitive spots inside the hole kept interrupting Jason's train of thought. It became incredibly difficult to form a complete sentence. Bruce placed his hand on Jason's protruding abdomen and pressed gently, causing the already swollen bladder to suffer even more, while the urge to defecate from the back hole also intensified. Jason wanted to curl up to resist, but the alpha forcibly straightened his body.
“I love you, Jaylad.” Bruce’s voice carried a certain magic. “And you love me too, don’t you? I know the truth, Jason. Because I feel the same way. You were my partner, my Robin, my omega.” He drove upward hard, burying himself into the tight, warm softness within Jason’s womb.
“Cum for me,” he said.
The direct command from the alpha leader made Jason tremble all over. It felt so wrong—and yet so good.
This feeling made Jason forget that the Earth revolved and rotated.
This feeling made Jason forget that the sun rose and set.
This feeling made Jason forget Gotham and the vigilante life.
This feeling made Jason forget… who he was.
In the relentless flood of orgasm, he felt the alpha’s knot swell and lock at the base. Liquid spilled without distinction between urine and slick, along with something thicker sliding out of his anal. The shame of release struck his chest even before the pleasure did. Jason’s eyes flew wide open, unable to speak.
His consciousness slipped away.
Bruce held Jason, whose gaze had gone unfocused, and kissed his lips before carefully cleaning out what he had just released. It was a jelly-like mass. Bruce placed it into the glass jar he had prepared in advance, filled it with nutrient solution, and sealed the lid. Looking at the lifeless omega lying in the nest, he smiled and pressed a gentle kiss to the side of the jar.
“Jason, it’s time to go home.”
