Chapter Text
It was supposed to be a normal patrol. Clark was in Gotham helping Bruce on a drug smuggling ring. Their intel pointed at a possible connection in dealings between Metropolis and Gotham. Bruce was strict with his no meta rule in Gotham, but he always seemed to fold when it came to Clark. When Clark had proposed working together on the case, Bruce agreed with no hesitation. Dick later teased him about his eagerness, hinting that Batman had a crush.
He didn’t have a crush on Clark, that would be ridiculous. He’d known the man for over a decade and felt nothing outside the realms of friendship. Sure, Bruce trusted him more than others but that didn’t mean anything. He trusted plenty of people - his family, the Justice League. He just felt connected to Clark in a way he had never experienced before. He admired the man deeply, always astounded by his actions.
He was dazzling, it was hard not to notice. And Bruce could admit he was an attractive man. Maybe when he was younger Bruce might have pursued something, but the time for that passed. Clark was with Lois for years; they had a family together. It had been a few years since their separation, but they still remained the best of friends. Bruce was a little envious of Lois, though he would never admit it. Part of him wanted that closeness the two of them had. Bruce knew that Clark cared for him, just not in the same way he cared for Clark.
Still, Bruce couldn’t help but admire the way Superman’s muscles rippled through his suit as he took down criminals. He was careful with his punches, always being extra cautious not to hurt anyone too bad. The way his hair was slightly swept across his eye, the curl looking as beautiful as ever, had Bruce mesmerized. Clark had managed to take care of the surrounding criminals and turned towards him. Bruce’s eyes stared at his chest as he turned to face him, mouth going dry. Okay, he might have a little crush.
“B? Everything okay?” Clark said as he waved a hand in front of Bruce’s face to get his attention.
Bruce blinked back into attention and cleared his throat. “Fine, Superman. Good work.”
Clark shot him a blinding smile. Bruce felt his heart clench at the sight. Suddenly, Clark’s eyes widened as he pushed Bruce out of the way. Bruce looked up in time to see Clark surrounded by a red haze. He covered his mouth as he tried not to breathe it in.
Clark saw Bruce about to jump to save him, causing his hands to leave his mouth as if to push Bruce away.
“Stay back!” Clark screamed, not thinking as he inhaled the toxin.
As soon as it appeared, the gas vanished. Bruce was at Clark’s side as he collapsed.
“Superman, report.” Bruce said as he positioned Clark into the upright position.
“Hurts,” he said as he began to shake.
Bruce cursed under his breath before he threw Clark over his shoulder and sprinted for the batmobile. On the way to the cave, he broke every possible speeding law. He went as fast as he could, motivated by Clark’s unconscious form in the back.
Arriving at the cave, Bruce wasted no time before putting Clark on a cot to begin analysis of the toxin. Bruce felt a little tension bleed from him when it came back negative for kryptonite. After running through hundreds of possible poisons, it finally landed on one. A version of Ivy’s sex pollen. It didn’t seem deadly, just a pain in the ass. Bruce sighed, wondering how he was going to deal with this. He could potentially call Lois and ask her to help Clark out, but that sounded like a disaster waiting to happen.
He made his way to Clark’s side and brushed his hair out of his face. Clark was sweating, which Bruce didn’t know was possible. His eyes were cracked open and turned to look at Bruce.
“Clark, you’ve been hit with a variant of Ivy’s sex pollen. It isn’t lethal, but it may take a few days to get out of your system. Because it’s a variant, I do not have the antidote available. I can begin analysis on one but I can’t guarantee when it will be ready.” Bruce said, thankful Clark’s eyes had opened to show a clear gaze. “I’d like for you to stay here at the manor until this is out of your system, just in case anything were to go wrong. We do not know yet how it will affect your Kryptonian DNA. Do not feel pressured to stay if you do not want to. I could call someone to help you out with this, or I could bring you home. It’s up to you.”
Clark pushed himself up, slightly panting as he did. His breathing was a little ragged but he still seemed level headed. Bruce sighed in relief at that. He wasn’t sure how he would deal with a Clark that had succumbed to the toxin’s effects.
“I want you to help me,” Clark said as he stared into Bruce’s eyes.
“Of course. I’ll have Alfred prepare a room and get to work on preparing the antidote.” Bruce said as he moved to walk towards his equipment.
Clark grabbed his hand causing him to halt in place.
“No Bruce, I want you to help me.” Clark insisted.
“Oh.” Bruce didn’t know what else to say. The toxin must have started to affect Clark’s sense of logic.
“Don’t feel like you have to. I’m just feeling off, but I don’t think it’s anything to be worried about. I would just rather not spend this alone and I trust you more than anyone; I want you with me for this.” Clark admitted, eyes pleading with Bruce.
Bruce inhaled sharply, not knowing what to do. He looked into Clark’s eyes and searched for any sign of doubt. He found none. Clark really wanted this with Bruce. Bruce opened his mouth to agree but -
He shouldn’t. This could jeopardize their whole friendship. Years of love and trust put into each other and it could all be ruined by this one choice. But how Bruce wanted to agree. He wanted nothing more than to be with Clark, even if just for one night. It could be his only chance of having him that close. His heart overpowered his head and made the decision for him.
“Okay, I’ll help you,” Bruce agreed. “I need you to tell me exactly what you expect and what you are comfortable with."
“I’m comfortable with anything because it’s you. I want it all,” Clark said with a slight growl in his voice. His eyed Bruce hungrily.
“Okay,” Bruce said, trying to keep himself together. “Follow me.”
Bruce took Clark upstairs to the main level. He quickly needed to inform someone of the situation before Clark lost control. He found Dick and Tim watching TV and exhaled. He took one look at Clark and could tell his self control was slipping.
“Boys,” Bruce said, pulling their attention to him.
“Oh hey B. Hi Clark. You okay there bud? You’re looking a little red.” Dick said as he took in Clark’s appearance.
“Clark was hit with a variant of Ivy’s pollen. He will be staying at the manor for the time being. I will be taking a few days off to help him. Tim, you will find a sample in the analysis chamber. I would appreciate it if you created an antidote. The sooner the better,” Bruce said as he turned to quickly leave. This was already mortifying enough, he didn’t need to hear his son’s reactions.
“You’ll be helping him - OH MY GOD!” Tim screamed as he recoiled in disgust. “You did not just tell us that! What the fuck that’s so gross. I’m literally scarred for life.”
“That is something I never wanted to think about,” Dick said with a grimace. “But don’t worry about it. Mission clear, get to work on antidote. We’ll make sure you aren’t disturbed.”
Dick pulled Tim away from the living room, sparing them all from the embarrassment of that conversation.
Seeing that they were alone, Clark swooped Bruce into his arms and flew them to Bruce’s room. The next thing he knew, he was on his bed. Clark was over top of him and quickly claimed his lips. Bruce froze in shock, mind struggling to keep up with the physical sensations of Clark touching him. There was a hand on his back, pulling him until they were touching chests. Clark’s groin covered his own. A roll of Clark’s hips brought a gasp from Bruce’s lips. Using this opportunity, Clark’s tongue invaded his mouth. Bruce melted at the sensation.
He felt himself relax under Clark’s fingers, letting them claim anything they desired. They kissed messily, a sort of desperation between them. Years of pent up tension breaking into a fierce explosion. Bruce melted, Clark pulling soft gasp out of him with every movement.
Clark used his speed to undress them, their heavy armors preventing any real contact. Bruce was shaken as Clark peeled off his suit. The force and speed at which Clark moved made Bruce flush in arousal. He loved that Clark could just control the situation like that. He was strong, and Bruce ached to feel those hands on his skin.
Wearing nothing but their boxers, Clark draped his body back over Bruce. He began to pepper kisses down Bruce’s neck. Bruce turned his head to the side to allow Clark better access. Clark sucked at the spot behind his ear and Bruce moaned. He was shocked that such a small action could pull such a sound out of him. Clark looked up at him and there was hunger in his eyes. He spent his time marking up Bruce’s neck, fueled by every sound he was pulling out of Bruce.
Bruce felt hot. It was like every part of him was being covered by Clark. He could no longer contain the sounds he let out, moaning openly for Clark.
Clark brushed against his nipple with his thumb, leaving Bruce gasping. He gripped the sheets as Clark began to twist the nub. He moaned lowly, hips jerking forward for any type of stimulation. Clark grabbed Bruce’s hands and brought them above his head, holding them in place. Bruce knew that if he pushed against them, he could easily break free. Still, he let Clark trap his hands, the idea of being powerless below Clark caused Bruce to feel lightheaded with pleasure.
“Please,” Bruce couldn’t help but whine. He felt a rush of shame rush over him. They’ve barely started kissing and he’s already begging Clark.
“Shh,” Clark said as he soothed him with a kiss. “Use your words, baby. You can have anything you want.”
“I need more,” Bruce said through labored breaths. He felt so sensitive and his cock was aching. It strained against his boxers, begging to be released.
Clark hummed in understanding and began to fully undress them both. He took his time removing Bruce’s boxers, kissing up his thighs and biting at the thicker flesh. Bruce threw his head back, hot pleasure surging up his body.
Clark firmly gripped his cock as soon as it was free. He ran his thumb over the slit causing Bruce to suck in a breath through his teeth. Clark pumped his hand as he returned his mouth to Bruce’s chest. Clark’s mouth attacked Bruce’s nipple. He began to suck and bite at it, determined to leave it swollen and aching.
Bruce couldn’t keep up with Clark’s movements. He felt the pressure building up inside of him but he needed something else.
“More,” Bruce demanded as he stared down at Clark.
Clark gave him a mischievous grin, He quickly scanned the room and used his speed to grab something out of Bruce’s side drawer. Bruce had barely blinked before he heard the click of the bottle opening and felt a cold finger at his hole. Bruce shivered in anticipation and tried his best to relax. Clark slowed his movements with his other hand but didn’t stop fully, keeping Bruce right on the edge.
Clark carefully inserted one finger, slowly moving it to encourage Bruce to open up. He took his time exploring Bruce’s inner walls before he deemed Bruce ready for a second. Bruce withered under his fingers. He squirmed against the sheets as he felt himself about to spill over. Clark moved two fingers with precision inside of Bruce, lasering in on one point. Bruce saw a blinding light and felt himself finish. Eyes refocusing, he saw Clark licking himself clean of Bruce’s cum.
He kissed Bruce again, quickly dominating his mouth. Bruce was putty beneath him, pliant in his hold. Bruce felt his body under attack by Clark’s fingers. Clark hadn’t stopped his movements inside of Bruce. He had worked his way up to three fingers, making Bruce moan as he pushed himself back down against Clark’s knuckles. It felt so good.
As quickly as he had worked them in, Clark removed his fingers. Bruce whined at the loss, suddenly feeling empty. Clark kissed him silent, as he lined himself up with Bruce’s hole. Bruce shivered with anticipation and did his best to relax his body. Clark began to push in, causing them both to groan in pleasure. He moved slowly, allowing Bruce time to adjust.
He was big, bigger than Bruce had imagined. But it made him feel whole in a way, like an empty void was slowly being filled. Once he was fully seated, Bruce let out a slightly pained breath. It was quite the stretch. He had never felt something quite like this. Clark’s cock seemed to have slight ridges in it, pushing gently at Bruce’s insides making the man moan at the feeling.
Clark rested his head against Bruce’s shoulder catching his breath for a moment. Bruce took the opportunity to kiss Clark gently. Clark’s eyes met his with a loving gaze. Bruce swallowed as Clark pulled away to look at him fully.
“You’re beautiful,” Clark said, as he brought his hands down Bruce’s chest, admiring every inch of it.
“Clark,” Bruce choked out. “You aren’t thinking straight. The toxin is beginning to affect you.”
“You are the most beautiful thing I have ever seen. I truly am blessed to have you here like this,” Clark said before he captured Bruce’s mouth once more.
“I am thinking as straight as you are right now,” Clark said as he pulled away from Bruce’s searching lips. “I’m still in control of myself, I don’t think that’s going to change. My body is tingling in excitement because I have you with me. I’m feeling so grateful to be able to share this with you. I’m lucky to have you.”
Clark began to devour Bruce’s mouth, not giving him a chance to argue back. He sped up his movements until Bruce was gasping for air. Clark pounded against him with a bruising speed. His hands firmly gripped Bruce’s hips with enough force to leave finger prints behind. Bruce screamed as Clark hit his spot.
“There it is,” Clark said as he adjusted their position. He shifted Bruce so that one leg rested on his shoulder, allowing him deeper access. Bruce’s eyes rolling back as he lost himself in the pleasure. Clark reached so deep within him. He felt so full, so close to Clark. He allowed himself to fall into it.
He shook as Clark pulled another orgasm out of him, a scream escaping his lips. Clark didn’t slow down his movements. If anything, they picked up. Bruce’s body screamed from overstimulation yet he found himself relishing in the pain. He groaned as he felt his cock twitch in interest. There was no possible way he could go again after two back to back orgasms. Clark didn’t seem to care. He chased his own release, gripping Bruce’s thigh as he pounded into him.
Clark suddenly halted and groaned in discomfort. His hand coming down to touch where he and Bruce were connected. He pulled out of Bruce suddenly causing Bruce to gasp. He whined in discomfort, missing the warmth of Clark’s cock inside him.
“Clark?” Bruce asked, adjusting himself to lean against Clark.
He grasped his dick, gritting his teeth in pain. Bruce watched as it swelled the tiniest bit, turning red at the tip. He took in the slight differences between himself and Clark. Unlike a human cock, Clark’s had raised lines going down the sides. He was thicker than the average person, longer too. His tip didn’t have the average slit. Bruce noted that the cross section looked like it might open like a flower.
“I can’t come,” Clark said, a little desperately.
“It’s okay, I’ll take care of you.” Bruce said as he lowered his mouth onto Clark’s cock.
He began to suck what he could fit in his mouth. Clark’s tip was heavy on Bruce’s tongue as he sucked greedily. He took his time admiring the shape of it, how the swirls running along Clark’s cock protruded in his mouth. Clark threw his head back as he moaned. He gripped Bruce’s hair and pushed him down further. Bruce choked slightly but Clark didn’t relent.
He began to fuck Bruce’s mouth, causing Bruce’s mind to blank. He could hear Clark talking to him but Bruce paid him half a mind as he lost himself in the pleasure of being used by Clark. Still, certain things broke through to him and made him whine at the praise.
“Take it like I know you can,” Clark said. “You’re so strong, I know you can handle this.”
Bruce tried to hollow his cheeks as Clark pushed past his lips.
“You’re always there for me. I know you can take whatever I throw at you because you are strong, so fucking strong,” Clark said as he stared lovingly into Bruce’s eyes. It made him melt even further. “You have no idea how much restraint it takes watching you lead League meetings. It takes everything in me not to strip you down and take you right there. You’re such a powerful leader, it makes me proud to call you mine.”
Bruce felt tears form in his eyes. He wasn’t sure if it was because of Clark’s words or because of his lack of air. He was beginning to feel light headed, only partially from the pleasure. He tapped Clark’s thigh twice and was immediately able to breathe as Clark pulled out of his mouth.
He choked for a minute, trying to catch his breath. Clark stared at him in panic, pulling away slightly from Bruce.
Bruce quickly grabbed Clark’s hand to prevent him from moving further away.
“Clark, it’s okay. I’m fine,” Bruce said as he used his free hand to lift Clark’s chin and met his eyes. “I just needed a second, you didn’t do anything wrong. I enjoyed that, probably a little too much.”
“You - you liked that?! Bruce, I could have hurt you! I wasn’t controlling myself. I shouldn’t have gone too far.” Clark said as he ran a hand through his hair.
“Yes Clark. Some of us have these things called kinks. I just so happen to like not having to be in control sometimes. That doesn’t mean I don’t like it the other way around. It’s just nice to let go sometimes.”
“Bruce, it’s not like that. I would never shame you for what you like. It’s that I went that far without asking you first. Maybe I’m not as in control as I thought. It feels weird,” Clark said as he continued to grab his dick. “It feels like I have to cum but I can’t. It doesn’t hurt but it feels like something is building up. I’m beginning to feel a little desperate.”
“What can I do to help?” Bruce asked as he climbed into Clark’s lap.
“Being in you helped. It helped relieve the pressure,” Clark said as he fingered at Bruce’s hole. “Felt like I connected with something that I had been missing my whole life.”
“It made me feel whole,” Bruce admitted before he could stop himself. He was beginning to feel hot, his control slowly waning. “Can I sit on it for now? I can’t go again just yet so don't get any ideas."
Clark nodded his head eagerly in agreement. Bruce positioned himself above Clark and used his hand to guide Clark to his entrance. He sighed at the sensation. Clark felt slightly bigger, flaring a little at the base. He couldn’t help but moan at the feeling of being stretched wider. He grinded against it in a testing manner. He felt satisfaction seep deep into his bones. He relaxed fully against Clark, letting his head fall onto his shoulders.
Clark wrapped his hands around Bruce and guided them to lie down. Bruce must have drifted off at some point because he was awoken to Clark rutting into him. He didn’t fully thrust but he whined with need.
“It’s okay, Clark.” Bruce said, bringing Clark’s attention to his face. He smiled gently as he nodded his head in approval.
Clark wasted no time before drilling into him. He continued with a punishing pace until Bruce was shaking from the force of another orgasm. Clark shivered as if something came over him. Bruce looked up at him with hazy eyes. He looked at Bruce as if he just discovered the answer to everything. He captured Bruce’s lips in a kiss that was so delicate and fragile Bruce was scared it would fall apart at any moment.
“I love you,” Clark said, holding Bruce’s gaze.
“Clark,” Bruce said, getting ready to argue.
“No, listen to me. This is more than just the pollen for me. You feel like you complete a part of me that was missing. Being in you makes me feel completed,” Clark explained, looking rather panicked.
“You mean with me?” Bruce asked, looking at Clark with a flat expression.
“What? Oh - ! Of course that, but also, kinda the other thing?” Clark said as he rubbed his neck.
“Explain.”
“Whatever this is right now is making me feel weird. It’s more than just not being able to cum. I can feel something building in me. It’s such a heavy pressure, but being inside you makes it easier for me to breathe. Making you feel good is getting addictive. You feel like home. My heart feels whole when I’m with you. It feels like I’m being drawn to you. Not in a sex pollen way, but in a maybe Kryptonian weird biology thing,” Clark rambled as his cock twitched with interest, causing Bruce to jolt as it moved inside him.
“A Kryptonian thing?” Bruce asked hesitantly.
“Something’s happening in me. Every one of my instincts is telling me to go to you right now, to stay by your side for this,” Clark said as he looked into Bruce’s eyes. “This thing that’s happening to my cock feels natural in a way. I can’t explain it, but it feels like something just got triggered and this is how my body is reacting. This has never happened before so I don’t know what’s going on.”
“Clark,” Bruce said as he kissed Clark’s cheek. “It’s going to be okay. We’ll figure it out, we always do.”
“You’ll stay?” Clark asked, looking shocked.
“Of course I’m going to stay. You said you need to stay by my side. I would never leave you alone,” Bruce said as he kissed Clark fiercely.
Clark flipped them over so Bruce was face down. Bruce gasped at the sudden show of strength. Clark bit one of his cheeks before he pulled them apart and sucked at Bruce’s rim. Bruce scratched at the sheets so hard they began to tear. Clark assaulted his hole with the ferocity of a starving man. Bruce melted under his movements, feeling his cock twitch in interest. He groaned at the thought of going another round but Clark still hadn’t finished. He figured they would be at this for a while.
And boy, did they go at it. Clark took advantage of Bruce’s flexibility and moved him into unthinkable positions. Bruce felt the stretch of Clark’s ever growing cock in every crease of his body. It must have been hours, and still no sign of relief for Clark. He was growing red in the face, movements becoming sloppy as he lost control. He was growing desperate searching for release.
Bruce was splayed under Clark, pinned down by his strong arms. He was completely boneless, all strength leaving him about two rounds ago. Bruce could feel something begin to tug on his rim. He looked down in confusion as Clark shoved it inside in one brutal motion. Bruce gasped in pain, suddenly feeling impossibly stretched. Somehow Clark had grown even bigger on the base of his cock, a knot forming securing him and Bruce together.
“You’re mine,” Clark growled in Bruce’s ear.
Bruce shivered at Clark’s words and the warm feeling pooling in his gut.
“And you’re mine,” Bruce said as he sent Clark a real smile.
A darkness clouded Clark’s eyes as he stared down at Bruce. He licked his lips hungrily before lowering his head.
“I’m going to breed you full,” Clark growled in Bruce’s ear. There was something primal behind those words. “Everyone’s going to know who you belong to when you’re full of my child.”
Bruce couldn’t help but moan at his words. The idea of everyone knowing he belonged to Clark was too appealing. He could almost imagine it, being round with Clark’s child.
“Give it to me,” Bruce begged. “Breed me.”
He didn’t have time to react before Clark threw his head back in a scream and released his cum inside of Bruce. Bruce moaned at the feeling, beginning to feel full from the added pressure. It didn’t stop. Clark continued to release burst after burst of cum into him, each sending a shock through Bruce.
Clark buried himself in Bruce’s neck and bit down hard on the juncture. Bruce screamed out in a mixture of pain and pleasure. Something warm overtook his whole body, making him feel whole. Bruce felt a spark of something growing within him, pulling him in towards Clark. He thought he understood what Clark was trying to explain earlier. It felt like they were being bound together.
Clark lapped away at the blood that pooled from his teeth marks. Bruce groaned as the pleasure faded and he felt the heaviness of his stomach. It rounded out slightly, like he was bloated. It felt amazing. It was something he didn’t even know he was craving. He was so full of Clark, it was just a physical reminder of him. Clark seemed to notice his fascination and placed a warm hand on his stomach. Bruce couldn’t help but groan in pleasure as Clark rubbed small relieving circles on the raised mound.
“Does it hurt?” Clark asked.
“Feels good,” Bruce said as he felt his mind begin to go a little hazy. He felt so safe in Clark’s arms, it was okay for him to wonder.
“I’m glad,” Clark said as he kissed Bruce’s forehead. “Are you sure it’s not too much?”
“No!” Bruce said, suddenly feeling panicked. He didn’t want the feeling to go away. He wanted more. “It’s okay. I like it.”
“You like it?” Clark asked, amazed at Bruce.
Bruce looked at him with cloudy eyes. “Feels good. Feel whole now.”
“Good. You make me feel whole too.”
Bruce could hear Clark groan as he felt the cock buried in him grow again.. His eyes met Clark’s panicked ones in confusion. Instead of a response, Clark buried his face in Bruce’s neck again and inhaled his scent.
“Something’s coming out,” Clark said between labored breaths.
Bruce didn’t have time to ask him what he meant before he felt something round begin to come out of Clark’s cock. Clark’s hips rutted against his own despite them being locked together. He panted as he felt Clark’s cock opening up. Bruce suddenly felt even fuller as Clark deposited something inside him. It felt heavy and created a slightly bigger bump in his stomach.
“Clark,” Bruce moaned between breaths. His eyes rolling back as he felt another wave of liquid enter him.
“I’m sorry, I’m sorry,” Clark chanted as he tried to catch his breath. “I think there’s more.”
Bruce groaned as the process repeated two more times. Neither him or Clark could move, Bruce being weighed down by his stomach and Clark from the bone seeping exhaustion. They struggled to catch their breath. Clark began to pepper kisses across Bruce’s face. He rubbed small circles at Bruce’s lower abdomen. Looking down, Bruce was shocked to see how much it had grown. It wasn’t huge, looking maybe a few months pregnant.
Clark used his x-ray vision to look inside of Bruce and gasped slightly.
“What?” Bruce asked, suddenly concerned.
“They’re eggs,” Clark said.
“Yes, Clark,” Bruce said, voice straining slightly. “I figured that out when you laid them in me.”
“I’m sorry! I didn’t even know I could do that!” Clark said as he hid his face behind his hands.
“This hasn’t happened before?” Bruce said, suddenly curious.
“No! This is mortifying,” Clark said in embarrassment. “I should have known my weird alien biology would screw this up.”
“Slow down, Clark,” Bruce said as he peeled Clark’s hands from his face so he could look at him clearly. “You didn’t screw anything up. There isn’t anything weird about your body. I love every inch of you.”
That pulled Clark out of his thoughts.
“You love me?” he asked as his eyes widened in realization.
“Of course I do,” Bruce said with a huff. “How could I not?”
“Oh,” Clark said, completely dumbfounded.
His arms quickly pulled Bruce into a tight hug. “I love you too.”
“I know, you said so earlier,” Bruce said with an amused sigh. “I’m not going anywhere.”
“The egg thing really didn’t freak you out?” Clark asked self-consciously.
“It’s definitely piqued my interest. I would love an opportunity to research it further at the fortress.”
Clark let out a deep laugh, all the tension bleeding from him.
“You’re perfect, you know that?” He asked as he stared lovingly into Bruce’s eyes.
Bruce grunted in response as he tried to sit up. He fell back against the bed in frustration, his swollen middle making the task incredibly uncomfortable at the moment. Clark eased them both up until Bruce laid against Clark’s chest. They sat against the headboard as they waited for Clark’s knot to deflate.
“So far, we’ve discovered that you can develop a knot and lay eggs,” Bruce said as he played with Clark’s hair. “Do you think it happened because of the toxin?”
Clark shook his head, “No. This feels natural, like it was meant to happen eventually. I don’t know how to explain it, but it’s almost like it was waiting for you to be here to finally show itself.”
“I’ve been here for years, Clark,” Bruce responded.
“Not like this,” Clark said as he kissed him. “I wasn’t lying when I said that you made me feel whole. I feel like something clicked in place for me, tying us together.”
“Would it be weird if I said I feel it too?” Bruce asked.
“You do?” Clark responded.
Bruce simply nodded his head. “I feel drawn to you, like I don’t want you to ever leave my side again.”
“That makes two of us,” Clark said as he captured Bruce’s lips.
“I don’t think this is over,” Clark said, causing Bruce to groan.
“I don’t know how much more I can handle,” Bruce said as he rested a hand on his stomach.
“You can keep going,” Clark said as he rested a hand on top of Bruce’s. “I know you can.”
It turns out the answer to how much he could handle was eleven eggs. Bruce had never felt so full. There wasn’t a single moment in the past few days that Clark wasn’t in him. It was like Clark had shaped a space for himself inside of Bruce. After that first day, Clark fell asleep inside of him and decided not to leave him empty.
Bruce’s brain had floated away ages ago. The edges of reality felt hazy. Pleasure was pouring out of every cell of his body. He felt addicted to the full feeling; he never wanted to be empty again. His stomach had swollen significantly, holding all of Clark’s seed. He had drained every drop from the man. If he moved too quickly, he could feel the eggs shift in his belly. They pressed against his insides heavily, making it difficult to breathe. The pleasure from the feeling left Bruce aching for more.
“Bruce,” Clark said as he kissed along his jaw. “You with me honey?”
Bruce groaned as he struggled to form words. His head was foggy, only focusing on Clark.
“Full,” was all Bruce could respond, slightly slurred.
“I know, baby. You did so good for me, took everything I gave you,” Clark said as he rubbed Bruce’s swollen middle.
“More,” he couldn’t help but beg. “Please.”
“I’m sorry, B. I don’t think anymore would fit in that tight tummy of yours,” Clark said.
Bruce felt tears of frustration form in his eyes. He didn’t know why he was feeling this way. His body was craving Clark and begged for more.
Clark kissed his tears away.
“Please,” Bruce begged. He felt crazed, body needing more.
“Shh, it’s okay.” Clark soothed. “I don’t have any more to give you right now.”
Bruce sobbed as Clark caressed his face tenderly. He held Bruce against him until his breathing had calmed.
He could feel Clark’s knot started to shrink and Bruce felt panic surge through him. He wasn’t ready for them to pull apart. He needed Clark.
Thankfully, Clark stayed in place, seeming to pick up on Bruce’s panic
“It’s okay, Bruce. I won’t move just yet, but we can’t stay like this forever. You need to eat something,” Clark said.
“Don’t want to be empty,” Bruce whimpered. His mind was fried, no longer thinking logically. If he was in his right mind, he would be ashamed of how he was acting. But Clark made it so easy for him to let go, his presence melting away at any anxiety in Bruce’s mind.
“You won’t be sweetheart,” Clark said as he rubbed Bruce’s stomach. “You’re carrying me right here.”
Bruce couldn’t help but moan at the thought. He was so full, it was mind numbing. He calmed down slightly and relaxed against Clark. His mind began to drift off as he melted under Clark’s warm hands.
He was awoken by the feeling of Clark pulling out. Bruce brought a hand down to hold him in place without thinking. Clark captured his wrist and brought it to his lips, kissing at his pulse.
“You with me Bruce?” Clark asked, looking deeply into Bruce’s eyes.
“Yes,” Bruce forced himself to say through gritted teeth. He was still so exhausted despite his power nap.
“You were pretty out of it baby,” Clark said as he kissed the corner of his mouth. “Did you feel good?”
Bruce nodded and pulled Clark in for a deep kiss.
“I’m going to pull out now,” Clark said. Bruce opened his mouth to protest but Clark kissed him silent. “No complaints, we can’t stay like this forever.”
Bruce grumbled unhappily but let Clark continue. He felt his muscles contract in protest, trying to pull him back in. Clark kissed every complaint out of his mouth. Eventually, he was out and the rush of liquid Bruce expected to leave his body stayed in place. He looked down confused, looking to Clark for an answer. But Clark looked just as unsure as he was.
He brought his hand down to his entrance but found nothing leaking out. Bruce couldn’t help the sigh of relief he let out. Clark’s release was still in him, he could breathe easier knowing it wasn’t leaving him.
“I guess we can add that to the list of discoveries,” Clark tried to joke. His smile faded with the withering look Bruce gave him. “Sorry, bad timing.”
Bruce groaned as he tried to sit up. He wiggled back and forth as he struggled. Eventually, Clark took pity on him and helped him up. His stomach sloshed, causing the eggs to press against his insides. A small moan escaped Bruce’s lips. He was more into this than he wanted to admit. Thankfully, Clark didn’t comment on his moan as he helped him stand. Bruce’s legs shook for a moment before his knees gave out. Clark caught him in his arms before carrying him to the bathroom.
He positioned Bruce on the ground as he started the shower. After the water heated enough to his liking, Clark began to carefully clean Bruce. Every bit of tension bled from Bruce’s shoulders as Clark’s careful hands wiped him down. Shampoo got in his eye as Clark washed his hair causing Bruce to scrunch his nose in discomfort. Clark kissed his nose as he rinsed his head.
He took a moment to kiss Bruce, before he began to leave small kisses down Bruce’s throat. He began to lick at the still healing bite mark. Bruce could tell Clark took pride in his work, based on the dedication he showed to appreciating it with his lips. Only once Bruce pulled Clark’s head away did he stop. Bruce looked into Clark’s eyes and saw a spark of something he couldn’t identify. Clark shook his head as if trying to shake himself into thinking straight. He turned off the shower and toweled them both dry.
Clark quickly dressed Bruce, picking a loose shirt to cover Bruce’s swollen middle. It did a horrible job of hiding it. Bruce felt his mind start to wander off again, being pulled towards that safe head space. He was jolted out of it when Clark picked him up and started to leave the room.
“Clark!” Bruce shouted, trying to release himself from Clark’s grasp. “What are you doing?!”
“Getting us some food,” Clark explained gently.
“What if someone sees us?” Bruce asked nervously.
“It’s your family Bruce. I don’t think they're going to judge us for sleeping together.”
“Not that Clark,” Bruce said, clearly exasperated. “Look at me!”
Bruce gestured to his swollen stomach. Clark huffed in amusement as he kissed Bruce’s forehead.
“It’s going to be fine. I’m sure no one’s even awake right now.”
Clark was proven wrong as soon as they entered the kitchen. Bruce had hoped none of his children were awake, given the hour. But it seemed they had gotten back from patrol late and were hungry. Dick had a piece of bread shoved in his mouth while he stuck his head in the fridge. Tim and Jason were arguing over a boiling pan with Damian trying to stir. Duke tapped away on his phone while Cass sat on the counter and took in the chaos.
All eyes turned towards the pair when they heard Clark enter. There was a moment of silence as his children stared at him in Clark’s arms. He tried to hide his stomach with his arms but failed to do so because of the size. Chaos erupted throughout the room. Dick’s mouth was gaping open, dropping the piece of bread. Tim screamed in horror and Jason laughed his ass off. Damian looked confused as he lifted a questioning eyebrow at his father. Duke began to quickly type away on his phone, muttering something that sounded like “Stephanie and Barbara are gonna be so mad they’re missing this.”
Cass, who used to be his favorite, approached Bruce hesitantly and placed a hand on his stomach.
“Baby?” She asked with a slight smile on her face. “Little sister?”
Jason, who had just pulled himself together, started laughing harder. Bruce hid his face in his hands, wanting the floor to swallow him whole.
“Okay, enough of that,” Clark said as he cleared his throat. “Your father is exhausted.”
“Oh, I’m sure he is,” Jason said through snickers. “I’m sure it’s been a rough and fulfilling few days for him.”
“Jason!” Bruce screamed, finally finding his voice.
“Okay, sorry. I’ll stop now,” Jason said as he wiped away tears. “This is just too good.”
Bruce shot him an unamused look.
“I mean, you disappear for days and show up looking like that! How else are we supposed to react?”
“Okayyyy,” Dick said as he shut Jason up by slamming a hand over his mouth. “Sorry, B. Just took us by surprise.”
Bruce grunted, still refusing to make eye contact with anyone. Clark positioned him gently in a chair but slightly shook Bruce as he released him. Bruce felt his stomach jostle and couldn’t help but groan slightly in pain. The pleasure he previously felt had almost fully dissipated, leaving behind an aching heavy weight. Clark kissed his head in an apology and made his way to the stove. He ushered away the children and got to work trying to salvage whatever monstrosity had previously been cooking.
“Are you in pain?” Tim asked, as he joined Bruce at the table.
Bruce grunted in response, not wanting to talk to his children about this now, or ever.
“You get attacked by a vampire B?” Duke asked curiously as he glanced at the bite mark on Bruce’s neck.
Bruce brought a hand up to his neck in an attempt to cover it. He hadn’t given it much thought, mind being distracted by everything else that happened. When he looked in the mirror earlier, he observed that the wound wasn’t healing like normal. Bruce had received other bite marks over the last few days but they were all on their way to healing. This wound was much deeper but didn’t look bruised in the slightest. It made Bruce pause, wondering if this was another unknown from Clark’s newly found biological responses. He just added it to the list of things to research when he got to the fortress.
Damian slowly made his way to Bruce, head hanging lowly. Bruce gently lifted his son’s head so he could look him in the eye. Damian looked anxious, contemplating something deeply.
“Does this mean you are replacing me, father?” Damian asked.
“What?” Bruce asked, shocked by Damian’s question.
“The baby,” Damian said as he looked at Bruce’s stomach. “You’re going to have a new blood heir. I’m no longer needed.”
“Damian, look at me,” Bruce said as he stroked his fingers down Damian’s cheek. “You are not being replaced so you have no need to worry. No one could ever replace you, any of you. Besides, there isn’t a baby.”
“Yet,” Clark couldn’t help but interject.
Bruce grabbed the first thing he could get his hands on, which happened to be a spatula, and threw it at Clark’s head with scary precision. Clark easily dodged it and shot Bruce a blinding smile.
“So there is going to be a baby?” Duke asked, finally looking up from his phone.
“No!” Bruce said as he threw his hands up, exacerbated. “There is no baby! We don’t even know if it’s possible.”
“But you want one, that’s what I’m hearing,” Dick said smugly as he winked at Bruce.
Bruce could feel his muscles starting to tighten again from frustration. This is why he was always so tense, his children were menaces.
“Little sister,” Cass said, nodding her head in agreement at the idea of another sibling.
“Maybe one day, Cass,” Clark said as he pulled her in for a hug.
“Clark, stop giving them ideas,” Bruce growled. Still, he couldn’t help but rest a hand on his stomach at the thought.
Clark hummed happily, as he dished up several plates for everyone. He took a seat in the empty chair next to Bruce and kissed him firmly on the lips.
“So does this mean you guys are together now?” Tim asked as he shoved food into his mouth, not looking up from his plate.
“Yes,” Clark said as he wrapped an arm around Bruce, pulling him closer.
“About time,” Dick said. “I was getting tired of watching this guy pine over you.”
“Dick,” Bruce said as sternly as he could. “Shut up.”
“Ooo, I’m so scared.” Dick said as he shot Bruce a shit eating grin. “What are you gonna do? Roll after me?”
Bruce brought a hand to his stomach self consciously. He was beginning to feel uncomfortable in his skin. He was fully aware of how big he looked, he could feel the weight of it every time he shifted in his seat. Every part of him felt sensitive, being heightened by his fluctuating hormones. Tears began to form in his eyes out of sheer mortification. He felt humiliated, having to be seen by his family like this. What had Clark been thinking? Bruce knew that he was the one who asked for this, begged for it even. But now, being outside of Bruce’s bed, he began to regret it.
A sharp pain ran through him at the thought. It was like his body was rejecting the mere thought of regretting what happened. He felt a tight string inside him pull. The teeth marks on his neck began to ache. Clark seemed to pick up on his distress and wrapped a hand protectively around him. He pulled Bruce’s face into the corner of his neck. Bruce immediately felt his whole body relax, comforted by Clark’s scent.
“B?” Dick asked, suddenly aware of Bruce’s discomfort. “I’m sorry. I shouldn’t have made that joke.”
“It’s nothing,” Bruce said as he tried to pull himself together. “No need to worry yourself.”
“I made you cry, B. I think I can count on one hand the number of times I’ve seen you cry. Anytime you shed tears, I’m going to worry.”
Bruce chuckled to himself, knowing Dick had a point. He wasn’t the best at showing his emotions. But he refused to admit he was emotionally constipated, as his children loved to tell him he was.
“We won’t bother you with questions right now, this is obviously still a sensitive topic,” Tim said as he rested a hand on Bruce’s shoulder. “But you won’t be safe forever. I’m mentally scared from all of this. I will be getting my revenge.”
“I’m trembling in fear,” Bruce deadpanned. He couldn’t help it if his flat mouth twitched slightly into a smile.
“It’s late enough,” Clark said as he addressed everyone. “You all still need to get some sleep. Hurry up and eat then head towards bed.”
Bruce couldn’t help but smirk as Clark spoke to his children.
“You too,” Clark said, making Bruce look up at him in shock.
Clark smirked knowingly, “You’re exhausted. Eat so we can go to bed.”
“Only if you do.” Bruce argued weakly. He knew Clark was right, he could barely keep his eyes open.
“You drive a hard bargain,” Clark said as he quickly finished his food.
He waited until Bruce was done before he picked him up again. Bruce moaned slightly when Clark accidentally touched Bruce’s stomach with a little too much pressure. It felt overly sensitive, skin stretched tight over the cluster of eggs.
“Careful,” Bruce said through gritted teeth.
“Sorry,” Clark apologized with a kiss to his temple. “Good night everyone.”
Bruce grunted his goodbye as Clark carried him back to bed. Once under the covers, Clark pulled him into his arms and placed a hand lovingly on his stomach.
“You’re so beautiful like this,” Clark said as he kissed Bruce’s neck.
“The kids thought I looked weird,” Bruce muttered.
“They were just surprised, that’s all. They weren’t expecting it,” Clark said as he placed light kisses on Bruce’s face. “They love you no matter what.”
“But how do I deal with this?” Bruce said, voice starting to raise in panic. “I can’t go on patrol like this, I can barely move.”
“Don’t worry about that right now. Just rest, we can figure it all out in the morning.”
Bruce wanted to protest but found himself unable to respond as he succumbed to sleep.
