A Life So Changed

Chapter One:

Bruce stares at the pregnancy test that is in his hands, reading the results over and over again. He feels like he can't breathe, his heart is trying to pound its way out of his chest, and he's shaking. Batman is actually shaking in his bathroom from genuine fear. Bruce tries to stay calm because this can't be happening, not to him, not to Batman.

The pregnancy test that is in his hands has produced the word yes after he had taken it. It displays the word with a capital y and a lowercase e and s as if having the word yes be in sentence case on the test makes the news that much better. Of course, Bruce supposes, that it's better than the word being in all capitals as if the thing was screaming the results at him but even so; it doesn't make Bruce stop staring at the thing in horrified acknowledgment. It doesn't make Bruce stop shaking. It doesn't make Bruce breathe.

Bruce doesn't know what to do and the worst part is, is that he doesn't know what to do about the father. The father being Clark Kent. Clark Kent who works for the Daily Planet that Bruce just so happens to own. Clark Kent who is Superman and fights crime beside Batman. Clark Kent who is his best friend and who Bruce loves more than just friends. Clark Kent who is currently happily mated to Lois Lane.

Bruce sets the test down next to the other two he took — those ones saying yes as well but Bruce was in denial — and runs a hand through his hair, messing it up. He was hoping this wasn't the outcome when he decided to test for it. Lately he's been tired more than usual, dizzy, feeling nauseas, and having bad headaches. At first he thought it was just a mild cold but the more he started to think about it, the more his suspicions rose. In the end he decided to take a pregnancy test just to settle his thoughts. He never once believed the results would come back positive.

Bruce backs up until his back hits the wall and he slides down it, holding his head in his hands and resting his elbows on his knees. He thinks back to that one night after a long, hard mission that the Justice League dealt with; the one night that brought him to this whole situation.

...

"What were you thinking Bruce!" Clark storms in after him, the door to Bruce's quarters on the Watchtower sliding shut behind him. "You almost got yourself killed."

"I did what was needed to be done," Bruce responds, starting to take the Bat suit off. He's feeling overly hot and he can feel that his cheeks are flushed because of it.

"No, you were trying to be self-sacrificing once again." Clark looks agitated, standing there stiffly and eyebrows scrunched up in a furrow. "Someone else could have handled that. I could have handled it instead of you trying to be the martyr."

"I wasn't trying to be self-sacrificing." Bruce has gotten the top half of his suit off and starts working on the bottom half. His muscles feel sore, probably from the fight, and his eyes keep watering no matter how many times he wipes at them. "Everyone else, including you, were busy. Those people needed saving at that moment."

Clark steps up to him and Bruce abandons trying to get the rest of the suit off in favor of standing up straight. He won't let anyone, alpha or no alpha, intimidate him. The scent of anger and agitation is strong in the air and Bruce knows his scent mask is starting to wear off. Even though Clark already knows he's an omega, it still makes Bruce uncomfortable to be in Batman mode and smell like an omega around him. "You still could have called me. I would have come."

Clark's scent is rising, the strong angry alphaness of it filling the air to almost a suffocating degree. "And just left the people you were saving to die?" Bruce asks.

"They would have been fine!"

"You don't know that!"

"Gosh Bruce, you are so stubborn. It's the most annoying, most infuriating thing ever."

Bruce crosses his arms and tries to ignore his instincts telling him that he should appease the alpha and apologize for his outbursts. "Yeah, and you're just as stubborn."

Something like a growl emanates from Clark's throat and it's the first time Bruce has ever heard it. Clark must be angrier than Bruce first thought. He looks Clark in the eyes, stares him down; something that an omega is taught to never do with an angry alpha. When an alpha is angry, the omega is supposed to bow their head just like the beta, show submission. Bruce will never do that. He knows Clark would never ask him to.

By now they are standing very close, each of them in the other's personal space and in each other's faces. "Out of the two of us though, you're the most stubborn." Bruce huffs and crosses his arms over his chest. He's started to sweat now and he's feeling hotter and hotter as time goes by. "No, it's true. You like to get your way and you'll argue it until your blue in the face."

"Because normally I'm right."

"You're not right all the time, Bruce. I wish you would see that," Clark says gently. "I wish you would see that others care about you and want to help you. That we don't want anything to happen to you." Clark shrugs slightly. "I don't want to lose you Bruce."

"You're not going to lose me, Clark."

"You don't know that." There's barely an inch between them and the air is thick, making it hard to breathe. "I care about you so much, Bruce," Clark whispers. They're both breathing heavily, drinking in each other's scents that are ladened with a mixture of adrenaline, anger, and Clark's has a hint of alienness in it. It's almost intoxicating to Bruce.

Clark looks him in the eyes and Bruce stares at him right back. The silence is only a couple of seconds but feels like minutes before Clark takes a sharp breath in and then leans forward the rest of the way to Bruce, connecting their mouths together.

Their kiss isn't anything gentle and is instead a clash of tongue and teeth. One of Clark's hands come up to the back of Bruce's head, carding his fingers in his hair and pulling his head closer at the same time his other hand falls onto Bruce's lower back. The whole length of their bodies touch and Clark starts backing Bruce up. The back of Bruce's knees hit the bed and he falls down onto it. Clark follows and climbs on top of Bruce.

Bruce slides up the bed without breaking their kiss but eventually Clark breaks it for them. He moves his mouth to Bruce's neck and for a minute, a spike of fear shoots through Bruce's chest. He doesn't want Clark to mark him. That would mean they were mates and the two of them aren't mates. Bruce tries to remember why that is but as soon as Clark leaves his neck without biting him and moves onto one of his nipples, complete thought leaves his mind.

Bruce can feel himself getting wetter and wetter between his legs, his body responding to the alpha that is currently sucking and nipping at his nipple. It doesn't take long for the smell of lust to overpower the smell of anger in the room. It only serves to make Bruce and Clark's bodies respond even more to what they are doing. Clark moves onto the next nipple, treating that one in the same way he treated the other. His hands slide down Bruce's body, leaving hot trails until they reach Bruce's utility belt. Clark takes the belt off with ease, not even flinching at the precautionary defenses he installed in it. When the belt is discarded, Clark moves on once again.

Clark's mouth skims down Bruce's abdomen, tongue flicking out every so often to taste Bruce's skin. Clark spends some extra time at his navel, licking around and into it, causing Bruce to moan and push at Clark's head. At Bruce's insistence, Clark sits up and starts to peel away the bottom half of the Bat-suit. He smiles at the sight of Bruce not wearing any underwear while Bruce thinks about how he's going to have to clean the suit himself instead of Alfred.

"Why are you still clothed?" Bruce asks.

Clark smirks at him and in a burst of speed, is undressed. Clark leans over him again and rubs their erections together by rolling his hips. It feels good but nothing compared to the pure pleasure of being filled. But, of course, that's what he is made for no matter how many times Bruce tries to deny it. Omegas are made to be fucked and bear children. Bruce probably tries harder than most liberal omegas to deny that fact and work against it, but he can never deny the fact that being filled by an alpha cock is one of the best feelings in the world. He hates that he thinks this way.

But right now, none of that matters. "Come on Clark. Fuck me."

"You want that, huh?" Clark reaches down, probing between Bruce's ass cheeks with a couple fingers. He hums approvingly and starts to push two fingers into Bruce. "Gosh, Bruce, you're so wet."

Bruce groans at the feeling of those fingers entering him over and over. Omegas don't normally need to be prepared because of their natural lubrication and Bruce has been with plenty of alphas and betas that will do nothing but penetrate right off, but he also knows some of them like to prepare anyways. Lois is a beta and so Clark is probably used to prepping people he's about to sleep with.

Lois… Bruce blinks, his thoughts clearing slightly. That's right, Lois is Clark's mate. Lois is married to Clark. Bruce opens his mouth to say something about this fact but before he can, Clark withdraws his fingers and replaces them with his cock, sliding in easily. Instead of words coming out of Bruce's open mouth, a long moan does and that's the moment Bruce really can't think straight anymore because Clark is big and he feels so good.

"Clark," he breathes because it's the only thing his mind is thinking besides a mantra of fuck me.

Clark shivers above him and bottoms out, kissing the corner of Bruce's mouth. "You feel so good." He moves, a small little roll of hips until he gains speed and begins to pull out more and slam back in harder. "So good."

Bruce can hear the sounds of their bodies connecting, the lude wet smack of skin. He's drenched between his legs with slick and the smell is thick in the air. When Clark kisses him, enters his mouth with his tongue, he can taste the alpha hormone in Clark's saliva. Normally that would be used to help omegas in heat, to calm them by getting alpha hormones through that until the alpha comes. Right now, it has the same effect on Bruce and he can't get enough of it. His body is craving it, as if he really is in heat, but that's not due for another couple days.

Clark buries his face in Bruce's neck, Bruce tilting his head enough to expose his omega gland, almost wanting Clark to bite it. But that's a bad idea. The only thing is, Bruce can't remember why Clark biting him would be very, very bad. Clark breathes in deeply. "You smell nice. You don't normally smell like this. It smells… sweet."

He doesn't reply to that. Bruce is starting to enter into a haze that is also similar to his heat and that haze is making it very hard to think of anything besides fuck and knot. He looks around the room as Clark continues to lap at his neck, right where his omega gland is, and wonders what he is doing in his Watchtower room instead of his nest.

"Nest," he says at the same time he moans. Clark is starting to hit his prostate and it feels like heaven.

Clark raises his head and looks at him. "What?"

"Don't want." He looks around the room again. "Don't want to be here."

"You want me to stop?" Clark looks concerned and Bruce knows if he told him to stop he would without blaming Bruce at all. In fact, Clark would probably blame himself.

"No!" Bruce wraps his arms and legs around Clark, pulling him closer. Stopping sounds very bad right now and it's not what he wants at all. "Don't stop. Please don't stop."

Clark starts thrusting again and groans. "I don't know how much longer I can last, Bruce." Clark reaches in between them and takes a hold of Bruce's hard, leaking cock. He only has to stroke it a few times before Bruce is coming with a shiver. Male omegas don't produce much semen and penile orgasms are never as strong as anal orgasms for them, but it still feels good and makes Bruce moan. "I'm going to come, Bruce."

"Knot," Bruce says frantically. "Want your knot."

"You… sure?"

"Please alpha." Saying this seems to spark something in Clark because before Bruce knows it, Clark is pulling out, flipping him onto his stomach, and then reentering him with a hard shove. Bruce keens and can feel Clark's knot starting to swell. It doesn't take long for Clark to push in one more time, his knot swelling enough so he can't pull back out, and then coming inside Bruce. This is what sets off Bruce's second orgasm with Clark's cock grinding against his prostate and knot locking them together. The orgasm is intense and makes Bruce shiver violently and moan wantonly. Clark is moaning as well as he fills Bruce up with his come and Bruce can feel that there is a lot of it. But that's normal for alphas. Bruce reaches behind himself and pulls Clark's head to his neck. "Alpha."

Clark chuckles. "You don't need to call me that."

Bruce doesn't really understand why he wouldn't call his alpha just that but doesn't comment on it. He's starting to get a bit drowsy and all he wants is for Clark to bite his omega gland, mark him as his. But there's still that nagging feeling of that being bad for some reason. A reason Bruce really can't be bothered to figure out right now. He's feeling hot all over, hazy and sleepy, along with being satisfied. But he also feels like that satisfactory bliss is only temporary. He doesn't know why.

"My knot normally only lasts for about thirty minutes." Clark's voice sounds small, wary, and distant. "I…" There's a loud swallow. "Oh, gosh, Lois."

"Lois?" Bruce says, mostly to himself. What does Lois have to do with anything? Is his alpha cheating on him? Why won't Clark bite his neck?

"I can't believe I did this." He sounds panicky and Bruce wants to comfort him but he really is feeling tired.

"Worry later." Bruce reaches back again, cards his fingers through his mate's hair. He wants to tell Clark that he loves him but something stops him. Something that tells him that if he utters those three little words, the results will be catastrophic. "Tired. Sleep."

...

Bruce ended up falling asleep after that, not knowing what Clark did while he waited for his knot to go down. Bruce also doesn't really remember what happened after that. He remembers waking up on the bed alone, his body hot and drenched in sweat. Dried come was on his stomach but it was his own, while between his legs was still soaked with slick. He remembers being confused as he sat up and looked around the room, realizing he wasn't in his nest. He also vaguely remembers exiting his quarters and walking around naked, slick dripping down his thighs, and asking for "alpha". Bruce isn't really sure who helped him get home, thinks it was probably Wally who is the only other omega on the team. If there had been a beta on the Watchtower that day, then they would have probably brought him home but there weren't any betas around. Not that there are that many betas on the team to begin with, Kyle Rayner being the only one. The rest are alphas, him and Wally are omegas, and J'onn doesn't fit any of the castes. So it kind of left Wally as the only option to bring him home besides J'onn and Kyle but neither were around that day.

Bruce never confronted Wally afterwards to confirm his suspicions. He had been much more humiliated that his heat had come early without him realizing it and really didn't want to acknowledge the fact that he needed help getting home because of it. Clark had also been avoiding him like the plague. Bruce wonders if Clark told Lois about their little tryst or if he's keeping it from her. He's not sure them staying together is a sign of Clark not saying anything or if she had just forgiven him. Bruce is also pretty sure Clark didn't know Bruce had gone into heat early. He already knew prior to that happening that Clark had never been with an omega let alone an omega in heat. He wouldn't have known the signs or symptoms and since his alphaness is Kryptonian in nature, his body would have responded to Bruce being in heat differently. So there's no way Bruce can put the blame on him. Instead, Bruce should have realized he was going into heat early and had been able to stop it himself. He's solely the one to blame.

It also wasn't until he missed his next heat that he remembered that he hadn't taken a birth control pill that day. He doesn't normally take them outside of his heat because unlike what the tabloids say, he doesn't really have sex all that much. Yes, he's had random sex and he's even had random sex during his heats, but more often than not he doesn't have sex outside of his heat and then spends his heats alone. He didn't have a reason to take birth control. On the rare occurrence that he would have sex outside of his heat, he always made sure his partner was wearing a condom. But since his heat hit early, the thought never even crossed his mind.

Bruce groans, rubbing at his face and feeling sick. When he had missed his heat, he had thought it was due to stress, even with the thought of the birth control pill crossing his mind. He just didn't want to acknowledge that pregnancy was a possibility. It wasn't until he started getting sick and headaches along with feeling more tired than usual that he started to really entertain the thought. His missed heat was almost three weeks ago now and those symptoms started up two weeks after his heat was supposed to start.

There's a knock on the door, breaking Bruce out of his thoughts. "Are you alright, Master Bruce?"

Bruce sighs and lifts his head, leaning it back against the wall. "I'm fine Alfred."

"Very well Sir. I thought I would inform you that breakfast is ready."

"I'll be right there." Bruce gets up slowly, feeling a bit dizzy. He approaches the pregnancy tests carefully, picking one of them back up. He stares at the digital word yes. Clark has been avoiding him. That means Clark doesn't want to acknowledge what happened between them. That means there's no way Bruce can tell Clark about this.
