Chapter Text
Things were going well.
Bruce had made a checklist in his mind of how the night had to go. And so far, everything was going well.
He’d greeted Barry and Iris when he got off the transporter when he arrived at the watchtower. Iris had commented that she could smell a faint trail of pheromones when she hugged him. But he’d prepared a cover story. Truthfully, he hadn’t had a heat in a few years so he was taking a lower dosage of suppressants to level his hormones. It’s was a great cover story, the more details you include, the more others will believe it.
Plus, this would aid him in the long run. Changing suppressant could have side effects, even mock heat and pregnancy symptoms in some cases. Now he had a witness from when the time came for the hopeful news hit the Justice League.
Aside from that, nobody really noticed, and if they did no one commented.
He found Clark arrived before him. The Alpha was wearing tight jeans with a plaid shirt, which normally Bruce would hate, but plaid looked good on Clark, maybe too good. And the Alpha had even rolled up his sleeves so his musical forearms were showing. He felt his pheromones spike just from the sight alone. He couldn’t wait until the later phase of the plan.
And as predicted he was with Kara, and she had brought booze from all across the galaxy. So it didn’t take long for the drinking games to begin.
“Alright. Who wants to play beer pong?” Hal asked after downing his second cup of a very strange purple concoction he’d brought from a planet he’d visited for a Green Lantern mission.
Oliver never backed down from one of these drinking challenges so he quickly agreed, “I’m in!”
“Can I join?” Barry asked after he put all his gifts away.
Hal rolled his eyes, “You can’t get drunk, so you can’t play.”
In the end Barry was assigned as the judge to their competition. In the end they formed two teams, Hal, Kara, Iris, and Zatanna formed a team. While Oliver, Constantine, Clark, and Bruce formed another. Kara and Clark were allowed to join, under the technically that they’d only drink the drinks Kara brought that made even Kryptonians drunk.
Bruce had been reluctant to join. But Oliver had insisted that they needed someone else to make it even, and he’d need to down at least a few cups in order for his cover story to work for his plan. But the deciding factor was simply that Clark was the team, proximity was just what he needed. So he accepted.
And so the game began.
He stood next to Clark for the entirety of the game, except for when their turns came. When he’d first walked to Clark’s side he noticed the way the Alpha took an extra intake of breath and his posture straightened. Perfect, the Alpha took notice.
Not long after he felt a gush of wind and suddenly, Clark was offering him a drink. When the Alpha handed him the drink he’d been able to smell his pheromones, that addicting scent of sunflower fields and old books. He felt a shiver run down his body as he accepted the cup, he had to keep his eyes on the liquid to stop himself from letting out an Omega whine at having such a strong Alpha in such close distance. The drink was some type of alien scotch that Hal had brought. It was more bubbly than he expected and had a funny aftertaste, but other than that it wasn’t horrible.
He let Clark hold his drink when Constantine and Hal yelled at him to take his turn. He trusted Clark, and besides this could help stir the Alpha’s biological need to care for his Omega. And in turn, he watched over Clark’s drink when it was the Kryptonian’s turn to play.
He did feel a little guilty about dropping a pill into Clark’s drink, but this was a good cause, and he was sure Clark would forgive him once they were mated and had a little pup running around. So he quickly dropped it in while no one was looking. And as Clark grabbed the cup to celebrate having thrown the ball into one of the red solo cups lined up on the table, he downed the altered liquid in a single gulp.
Bruce took another sip of his own drink to hide the smile on his face. Clark had taken the bate, the clock was now ticking.
/————-/
Clark had arrived early as preparation.
He’d give himself a look over before going through the zeta tube. He had the pill, his scent was strong, and he’d made sure to put on the nice plaid shirt that showed off his muscles.
He’d politely greeted everyone as they came into the party. Kara and Hal had already started setting up the drinks they’d brought while Diana had brought a bag full of snacks for the.
Kara had pulled him aside and asked if he going into rut given that she could smell his heightened pheromones. He’d brushed it off, simply stating that he had to be off his suppressants as they’d been clashing with his alien biology. She rolled her eyes and scolded him for the millionth time about using the ‘useless human suppressants’, she refused them and has spent months searching nearby planets for a similar herb to the one Kryptonians once used as suppressants. She’d only found a similar one with the help of a few kind Green Lanterns. They worked, though less effective.
It didn’t matter though, human suppressants worked fine on him, he just needed a witness who could explain his disappearance later in the day. If anyone asked she’d probably say he’d had to leave because he had in fact gone into rut.
But aside from her, no one seemed to notice. Everyone was giving off happy scents which were mixing in the air, so his didn’t stand out much in the crowd.
He found Bruce twenty minutes after he’d first arrived. The Omega was wearing a blue button up dress shirt with black dress pants, his hair was perfectly styled back. He looked as ethereal as ever. But most notably, he didn’t seem to be wearing a scent patch today! He must have thought it was safe to do so given he’s only be surrounded by friends. Clark could feel himself getting excited, he’d only have to wait though a few more hours to get his hands on the other man.
Truth be told, Clark was the one to ask Kara what kind of games she had in mind for the party. He knew she along with other party goers enjoyed their liquor, and he needed Bruce to drink a little so he’d let his guard down.
He’d ended up forming a team with Oliver and Constantine, as the human members voted that the only way to make the game fair was if each team had one Kryptonian player. He didn’t really mind, especially when their team only had three members and they needed a fourth. Barry was the judge, Diana was also disqualified, and Arthur didn’t enjoy these games. So Bruce had to step in and be the fourth player. Clark couple believe his luck, being in such proximity would make his plans a lot easier.
So the game started.
Bruce stayed at his side for the entirety of the game, except for then they went up to the table where the cups had been set up to take their turns. As Bruce’s pheromones were in such proximity he felt a shiver run down his spine, the scent of honey and lighting was so close he could so easily reach out. And he noticed the way Bruce’s cheeks got pink whenever he caught Clark looking at him. This was perfect, the Omega must have smelt his Alpha pheromones and took notice.
Clark knew it was time to put things into motion, so he used his super speed to grab both and himself and Bruce a drink. He’d taken a glass for himself of one of the drinks Kara had brought, he had to drink a little in order for Bruce to later on believe that he’d been drunk. And he grabbed an alien beverage that Hal had brought for Bruce, he was sure that Bruce had never tasted it before, so he wouldn’t be able to tell that the aftertaste was from the pill Clark had dropped inside of it when no one could notice.
Bruce’s cheeks got even more red when he accepted the cup, and Clark could visibly see how Bruce was already fighting with his inner Omega over having a prime Alpha right in front of him. Not to worry, the pill would make it much easier on him to give in. And he had to suppress a satisfied growl from escaping him as he watched Bruce take a tentative sip of the liquid.
Bruce’s trust was so strong that he even let Clark hold his cup for him while he took his turn. And so Clark so no trouble leaving his cup with his Omega while he took his own turn. That time he managed to score another point for their team and both he and Bruce took a victorious drink once he came back. He downed the liquid on his own cup and watched Bruce take another sip of his spiked drink.
Clark had to hide a smile as he wiped his mouth afterwards, it wouldn’t take long now for he effects to kick in, and he’d be right there to take care of his Omega once they did. And he himself felt his own body start to get warm.
/————-/
After a few more party games and eating some cake everyone had moved to the lounge area to eat some desserts and for Barry to open some of his presents. They were all having a fun time, except for Bruce. Bruce had to sit down on one of the couches in the lounge area of the watchtower. He had a headache and the bright lights were making it worse. And it was hot, way too hot.
But this didn’t make sense?
Sure he’d stopped taking his suppressants, but he hadn’t anticipated such a quick reaction. He’d been able to smell Clark’s pheromones. They were a little strong, but that was normal, his senses were heightened from the withdrawal. But he had to find a way to get Clark alone..
“Hey?” A voice called out to the Omega on the couch. It was Hal Jordan, he was carrying a dessert plate with a slice of cake on it and wore a worried expression on his face. “Spooky, you alright?”
Bruce pulled lightly at his shirt collar, it was starting to feel itchy. “What?” So much training and self discipline, he had to hide this and maintain control of the situation.
But Jordan calling him out brought on the attention of other party attendees.
His best friend Oliver, another Alpha, looked him up and down with scrutiny. “Bruce, are you okay? Your face is a little pink.”
Diana clicked her tongue, “I’ll fetch you a cup of water” and she left for the kitchen. Amazons didn’t have secondary genders, so Diana had some difficulty understanding how their biology and needs, but she always tried her best to help them.
But Bruce smiled as the Amazon handed him a glass of cold water. “Thank you. I’m sorry, I’m not used to drinking this much.” It wasn’t a lie, it’s not like he actually drank alcohol at events.
Hal let out a laugh, newly chocking on a piece of cake. “Put that on a tabloid! Bruce Wayne can’t handle three glasses of scotch.” He plopped himself on the couch opposite to the Omega.
“Hal!” Barry scolded his best friend as he came over with his own slice of birthday cake.
The Green Lantern shrugged his shoulders, “What? We all know he fakes being an alcoholic.”
Constantine rolled his eyes, “Please. Alcohol is a stretch.”
Hal leaned close to his best friend’s ear, “Seriously why’d you invite this guy?”
Barry let out a laugh and raised an eyebrow, “Would you rather I invited Guy?”
Hal’s face fell, “Nope.”
Bruce watched them quietly as he drank his water, it did help him feel better from the heat but the bright lights were still too much. He finished the glass and set it on a side table. He looked around, Iris, Zatanna, and Dinah were near the table with all the presents, Kara and Arthur were getting their slices of cake, and Mera had excused herself to the bathroom, but where was Clark? The Superman was nowhere in sight!
Diana looked down at him, “Do you need help standing up?”
The Omega shook his head, “I think I should do to my room…” well this put a damper on his plans. He had to get up and first where the Superman had….
“I’ll take you” Clark suddenly appeared right in front of him, almost as if he knew he was the person Bruce was looking for. He was looking down at the Omega with a warm smile and offering a hand to help him off the couch.
Clark had been in the bathroom. He’d calculated approximately how long it would take for the little pill he slipped into Bruce’s cup to take effect. And when the Omega had sat down on the couch with a flushed face and squinting his eyes, he knew it was time to act. So he quickly used his super speed to rush to the bathroom and check himself on the mirror, he had to look presentable for his Omega after all.
Bruce returned the other’s smile and took the offered hand. “Thank you Clark.” The Alpha’s grip was strong, and he kept holding his hand even as they stepped through a metal door that led to the member dormitories. Was Clark’s biology already telling him to not let this prime Omega get away? Gods he hoped so.
Meanwhile, Clark’s inner Alpha was screaming at him. He knew he’d stopped his suppressants so his inner Alpha’s urges would become louder and harder to ignore. But they were already so strong and all he wanted to do was bent this Omega down and bite his neck, was it Bruce’s pheromones affecting him like this? It didn’t matter, soon Bruce’s mind would surrender to his biology and they’d lock themselves in a room together.
They passed through a few more doors together before Bruce asked very quietly, “Is anyone following us?” His inner Omega was waking up, ready to present itself for the Alpha. But even pheromone drunk, Bruce would rather die than be caught in a vulnerable state by others. He wanted Clark to spend the night with him, he trusted Clark, not anyone else.
Clark let out a soft growl. He couldn’t help it. His little bat ever paranoid, of course Bruce didnt want anyone else to see him like, the Omega was barely walking straight anymore. And Clark hated the idea even more of anyone laying eyes on his claimed Omega. He swiftly used his super vision to look through the walls and sure enough the party was still active, they’d now pulled out some board games. “No, we’re alone” he whispered to the Omega.
Bruce let out a sigh of relief. “Good” the heat was coming back and he felt a little pressure starting at the base of his spine and his legs were feeling like jello. Stopping suppressants could lead to mock heat symptoms, though he chalked these ones up to arousal. He’d pre programmed the doors they just passed to automatically lock themselves behind them, they’d have to be broke before anyone could intrude on this moment. And lucky them, all rooms in the Watchtower were built to be completely sound proof, they were just a few doors away from his room now away he just had to….
Clark couldn’t take it anymore. The potent smell of sweet honey and lighting were flooding the hallway, he couldn’t hold back. He slammed Bruce against a nearby wall, caging him in. “Bruce….” Two pairs of blue eyes locked on each other, “..You’re going into heat!” The pill was just meant to arouse him, not trigger a heat cycle. But changed of conception were higher during heat, so really he wouldn’t complain if that were the case.
Bruce couldn’t stop starring. Clark was starring at him, panting and hunger in his eyes. The drug had worked! The Alpha was aroused and would take him tonight. But why would Clark think he was in heat? “No. It’s not….” He was cut off by the Kryptonian pressing his nose right onto his scent gland.
“You smell so good” Clark rasped as he took a large intake of breath.” He was addicted to this smell, he wanted to wrap himself in it and never leave. Soon, he told himself. Soon this Omega would be his and he’d be able to have this scent surrounding him every day for the rest of his life.
Bruce tried to control his urges despite the arousal forming between his legs. He didn’t know if Clark would remember any of this once he was sober. But in case he did, he needed Clark to think he’d been drunk. He used s Tibetan monk technique he’d learned to speed up his heart rate and forced himself to breath more heavily, “I’m…I’m to hot in this…” he grabbed at his shirt collar again, though with more vigor this time even popping a button off. “…I need to get to my room” he urged.
This was pure music to Clark’s ears. He’d fantasized about this moment so many times. He pulled his face back from the Omega’e neck. “Mine’s closer. You can use my bed” he placed both hand around Bruce’s waste and picked him up.
The Omega let out a surprised whimper. This wasn’t in his plans! He thought they’d end up in his room, but Clark’s room worked too. He grabbed at the Kryptonian’s shoulders with urgency, “Clark. You’re drunk” he spoke with fake concern.
“I’m fine” Clark brushed him off. He walked right past Batman’s room in the Watchtower and took a turn down the hall into his own room. He opened the door with his code and locked it behind them. His room, his den radiated with his scent, but now it would also be filled with Bruce’s scent, “You smell divine!” He lowered the Omega right onto his own bed.
“Alpha. Stop!” Bruce cried out. His head was swimming now. He’d just crossed right into the heart of Clark’s territory, his senses were just flooded with Clark, Clark, Clark…
“Call me that again” the Alpha crawled on top of him.
“I…” Bruce crawled back on the bed. He had to admit it was spacious, a full size. But he was still playing a part here, “I can’t, Clark we’re not….”
The Alpha growled again, “You can’t go out there. Let everyone smell you.” He was trying to hold himself back, truly was. Clark was also playing an act, he had to come across as an Alpha who gave into the urges but Bruce had to consent to it.
Just then, another wave of heat hit and Bruce pulled his knees up to his chest. “It hurts!” It cried out as he molded himself into a little ball. His mind was spinning, the Omega instincts he’d kept hidden for hears surfacing, “I-I need…..”
“What do you need” Clark purred, his pupils dilating as Bruce’s scent grew stronger in the small room.
“Alpha!” The Omega shouted. “I need an Alpha” his eyes started to water from the heat and pain all at once. Man this was exactly why he’d taken military grade suppressants to prevent his heats. They absolutely suck!
Clark hummed in understanding, he had to make his Omega comfortable. “Well…I’m an Alpha.”
Bruce blinked at him, tilting his head. “You’d….help me?” He tried to keep his voice in a soft and surprised tone and bit his tongue to suppress a squeal! It worked, it worked, it worked. He’d lured Clark in, and the Alpha was already offering himself to help.
Clark had to fight himself from growling. It worked, Bruce was looking so flushed and small, in his bed. It wouldn’t take much longer for him to get started on getting him pregnant. Internationally, he was smiling victoriously, but in the outside he simply nodded. “If you want me.”
Bruce nodded in return, “I want you.” The only Alpha he’d ever want, the only one he’d say yes to.
Clark got up from the bed, giving the Omega some room. “Okay then, take off your clothes” he used just a little of Alpha command in his voice. But it seemed like it wasn’t needed as Bruce rapidly hopped off the bed and started removing his clothing all on his own.
Well Bruce wasn’t gonna be told twice. His Alpha wanted to see him? He’d give him a show. He made quick work of removing his dress shoes and unbuttoning his pants. He’d only looked back when he started unbuttoning his shirt, Clark was looking at him with hunger in his eyes, good. He smiled seductively and removed his shirts, he was fully naked say for his underwear, he’d let Clark be the one to remove that particular article of clothing. He jumped back into the bed and frowned at the still fully clothed alien, “Alpha?”
Clark’s eyes were transfixed on Bruce’s body. Sure, he’d seen it before, in the showers, when Bruce was getting medical treatment. But this was entirely different, because this time he’d be touching, touching places that he’d kill any other Alpha for touching after tonight. And what kind of Alpha would he be if he kept his little Omega waiting? He smirked and started unbuttoning his plaid shirt, “Don’t worry Omega, I’m coming.”
Clark threw his shirt on the floor, followed by his jeans and shoes as he got back on the bed. Bruce closed his hazy eyes to get a better smell of his Alpha, “You smell so good Clark” he purred.
The Alpha growled in return, “Our smells are great together.” Clark got close enough to place his hands over Bruce’s waist again. He pulled lightly at the waistband of Bruce’s underwear with his dainty fingers.
Bruce felt a shiver run through his entire body as Clark snapped the elastic of his underwear. “I need you…” his voice trembled.
Clark leaned down to the shell of his ear, “I know what you need” he spoke darkly. “Let’s lie down” he pulled both of them back so they could get more comfortable.
“Wait!” Bruce placed both of his hands on Clark’s bare chest. His eyes were blown wide and his breathing grew labored again.
Clark’s scent spiked in panic! “What?” Had he done something wrong? Was the room not to his Omega’s liking? Did he want to build a nest? It was too early for the effects of the pill to have worn off so it had to be something else. But whatever it was he’d fix it.
Bruce gulped and the Alpha watched his throat boop. His face got more red as he looked down at Clark’s blue pair of underwear. “You’re going to…”
The Alpha chuckled once he followed the Omega’s line of sight. Of course he’d ask this, he knew Bruce wasn’t actually a playboy and that he mostly flirted with Betas anyway. Poor thing wasn’t used to seeing the full power of an Alpha. He raised an eyebrow, “Knot you?”
The Omega silently nodded.
This was part of the act. Of course he knew Clark would knot him, he kind of needed it for his plans to work out anyway. It had been a while since his last fling and the guy had been a Beta. Clark was undoubtedly larger than a Beta.
Clark chuckled again, “Yes.” Of course he’d knot his Omega. How was his seed supposed to take if he didn’t? It was cute honestly, having the dark and scary Batman looking so flustered and small.
Bruce sighed and nodded, as he was accepting the inevitable and certainly not like he’d planned this from the beginning. He cleared his throat, “But use a condom!”
“What?” The Alpha’s eyes widened.
“Use a condom” Bruce repeated, his expression hardening.
Of course. Of course Bruce would want to use a condom, the ever paranoid. Though maybe he hadn’t been entirely wrong for being paranoid. But this was just a Watchtower bedroom, it’s not like he kept condoms here. “Bruce I don’t have…”
“Here..” Bruce retracted himself from the bed, a little sad to pull away from his Alpha but this was impossible. He reached for the back pocket of his dress pants and pulled out the special box of condoms he’d gotten specifically for this moment. A.k.a, the box filled with poked condoms. “Alpha, use them” he handed the box over.
There was no way, absolutely no way. Sure Bruce always carried around Kryptonitemt that’s valid. Lollipops? Perfectly understandable. Bandaged? Made practical sense. Even the shark repellent Wa excusable. But a box of condoms to a League member’s birthday party?
Because also, if he’d brought a box of condoms….that could only imply that he’d been expecting to have sex. Right? Why would he carry this to a private event only frequented by their friends? But who would he even be planning to sleep with? He supposed it didn’t matter now, the Omega was with him and not anyone else.
“Okay, if it’s what my Omega wants” he accepted the box of condoms. Not like he couldn’t easily…I mean accidentally, pop them. “Now lie down little bat…”
(No smut here okay. Use your imagination if you must….)
“Are you ready?” Clark asked. He could feel it, his knot was about to form and once inside they’re be no going back.
Bruce felt the breach inside of him. Yes, this is what he’d wanted for so long. It felt right, no one else had ever felt so fight. “Yes. Knot me” he cried out. And Clark did.
Clark knotted him. It was so large that the condom did pop, the holes already having been poked on it only making it easier. Both men collapsed onto the bed as they’d be tied together for the foreseeable future, or at least unlit the knot went down.
Bruce laid his head on Clark’s sweaty chest purring contently, and with a single though running though his mind ‘I’m not leaving this room until I’m pregnant’ he’d wait for both their bodies to recover before asking Clark to go again.
And Clark placed a kiss on the Omega’s temple as he purred, which his inner Alpha screamed inside of him ‘We’re not leaving this room until he’s pregnant’. For now, he’d let the Omega rest, and once he was ready he’d take him again, he’d made sure Bruce didn’t leave without his seed taking.
…..they had three more rounds by the next morning.
