(( Smut warning! And let me just say it now, pregnant sex in Omegaverse is a mess. They both have contradictory urges and instincts, so it can change pace very quickly. It's written that way on purpose; it's wonky and bipolar as the chapter title says. And another thing, Keith's hormones are hard to manage. That's why he's combative one minute, submissive the next, and in this case... horny as all hell.))

Lance may have been a trainee. But he still ran around like a chicken with his head cut off during dinner rush. He hadn't sat down since school ended, and that was definitely speaking as to how busy he was.

He was walking home after helping clean up the dining room. It had to have been a hazing ritual or something, because Lance had vacuumed every carpeted nook and cranny of that place. He'd wiped down everything, organized the things on the tables, done exactly what he was supposed to. But, man, was he beat. The only thing that brought a smile to his face was knowing he'd get to see Keith once he got home.

He decided to send him a text beforehand.

Lance 10:17 PM- I'll be home soon

Lance 10:17 PM- Miss you

Keith 10:19 PM- I'll be here

When Lance came up to his house, the porch light was on, but the rest of the house was dark from the outside. He unlocked the door, entering quietly so he wouldn't wake anyone up . He knew that his brothers would already be in bed.

The alpha slid off his high tops after ever so silently shutting the front door. He crept up the steps, cursing every tiny creak that occasionally sounded from them.

Lance pushed his bedroom door open, flicking the light switch that made his lamp turn on. He stood stiff at the sight before him.

" Keith...?" He asked, dropping his now jumbled set of clothes. His mouth was hanging open after about a second or two, and Keith turned his head to face him.

Wow, leave it to Keith to be the subtlest person ever. He was sexily sprawled across Lance's bed, wearing nothing but those red, lacy underwear. Talk about the most arousing thing Lance had seen in a month.

" How was work?" Keith asked him in a sultry voice, and Lance didn't dare take an eye off of him as he closed the door and locked it.

" Exhausting... but... what are you doing?" Lance approached slowly; Keith only leered at him.

" Do you really need to ask that question?" The omega raised an eyebrow, biting his lip. These pregnancy hormones were driving him crazy, and his urges were all over the place. One minute he was salty, the next he was submissive, and apparently it'd worked its way into being horny.

Lance's alpha instincts were confused. His feelings were conflicting, because damn, Keith was smoking hot. But he was as tired as ever.

Keith had become sufficiently turned on over the past couple hours. It wasn't long after he'd had his talk with Veronica when his instincts kicked in. And to put it in the plainest of terms, they were making him crave Lance's cock.

" Keith... come on. I'm tired." Lance mumbled, though part of him really wanted to pounce on Keith. This was random of him, but it didn't matter. Keith's level of sex appeal was through the roof.

" Lanceee." Keith whined, and his inner omega was shining through in his tone of voice.

" Babe. Please?" The taller male sighed, gritting his teeth and almost shaking while trying to hold himself back.

Keith made a pouty face.

" Fine... I'll do it myself..." He said, trailing his hand downwards. His fingers danced over the lacy red fabric, lifting it up. Keith snaked his hand under, looking at Lance the whole time. He was already soaking wet for whatever reason, so his finger was slipping and sliding on his rim as he massaged it.

" God damn it." Lance growled to himself, crawling onto the bed. " You're sure you want me?" He asked while smacking Keith's hand away, and pulling it out of the lingerie.

" Do I have to spell it out for you?" Keith asked with an almost salty tone.

As much as Lance wanted to just assert his dominance and put his omega in his place, he knew he had to be careful. Keith was pregnant. And although there was no way his cock would reach the baby, he couldn't go rattling Keith's entire body. Nor could he spank him, or do anything rough. He had to be mindful of their positions, and not crush Keith or anything like that either.

" God... you're lucky you're pregnant..." Lance mumbled, baring his teeth a little out of frustration. He was already irritable from work, and now he couldn't even use this as an outlet for his anger.

Keith smirked up at him, moving his knee between his boyfriend's legs teasingly.

Lance leaned down, narrowing his eyes as he neared their faces.

" You better be quiet... if my brothers wake up, we're dead." He huskily whispered, and Keith didn't say anything before pulling him into a long awaited kiss.

The omega's eyes closed as he tangled his hands in Lance's brown hair. It was then that he realized, wow, for once... he was kissing more than Lance was. That was out of the ordinary.

" Actually kiss me..." Keith murmured on Lance's lips. What was the point of this if it was done lazily?

Lance groaned somewhat, feeling the knee in his crotch beginning to circle around his semi-hard member.

God damn it, Lance! Your omega was making this too easy for you, do something already.

His alpha instincts had contradicting urges, some of them he was able to act on. Others... not so much.

Keith realized that Lance was babying him due to the pregnancy. All he'd need to do was to get him more into this, then his primal instincts would take over.

The smaller boy scooted out from under him, and Lance looked really confused as he found himself being forcefully shoved into the pillows. He'd basically taken Keith's place.

" Keith?" Lance seemed lost.

Keith was busy undoing his khakis, fumbling with the button. He got it eventually, and was aggressively getting them off of Lance's tan legs.

Wow.

Okay.

These pregnancy hormones were throwing Lance for a loop.

Keith was almost like a ravenous animal as he peeled his alpha's boxers back. This wasn't as easy as he wanted. How hard was it to get laid around here?

He started pumping Lance's length, slowly coaxing it to full hardness.

" Why are you so horny?" Lance asked, and his tone wavered from the hand grasping his cock.

" How are you not?! I even busted out the lingerie..." Keith rolled his eyes. Even though the sexy underwear was originally his fantasy, Lance had taken to it more.

" Are you... mad?" The taller male's voice was reduced into a gasp.

Keith didn't answer with his words, but he definitely used his mouth. He wrapped his lips around the tip of Lance's member, licking and swirling his tongue all over it. All he wanted was to get fucked, and for that to happen, Lance's inner alpha needed to wake the fuck up.

Lance covered his mouth, knowing that they couldn't make much noise. So clearly Keith wasn't just reeling from hormones. He'd also accumulated a massive amount of sexual frustration. It was obviously pent up from the way he was acting, and sucking like there was no tomorrow.

Keith made a loud slurping noise, taking in a large portion of Lance's member with no warning. For a second there, the alpha feared that Keith was going to bite him in his angry state. But it thankfully didn't happen that way. Lance may have been a masochist, but he wasn't into getting his dick bit off. That would've been just... ew.

The omega wasn't even humming around Lance's cock. He was sort of growling while bobbing his head, but hey, it was still hot.

Lance would've been lying if he said he wasn't turned on now. He had Keith to thank for that. But damn, his alpha instincts were rejecting this. It almost seemed like Keith was in control, and that was the last thing they wanted. Lance had to fight it, however. Keith could do his thing for a little bit, even if he was rubbing Lance the wrong and right way at the same time.

" F-fuck..." Lance quietly stuttered. This sloppy blowjob was ironically one of the best ones Keith had given. With saliva going every which way, and the speed at which Keith bobbed his head, it was almost shoving Lance toward an orgasm. There wasn't any dancing around the point, and surprisingly, Keith hadn't teased him with his tongue at all.

Keith continued sucking, hoping that Lance was getting his message. It was his hormones calling the shots at that point, making him do these things like growl.

" Babe..." Lance reached down, letting his hands bury into Keith's thick, midnight black locks. " Th-that's enough." He said in an exasperated fashion, unable to take not being in control. That was the one thing pretty much every alpha sought. Dominance. And at the moment, Lance was being deprived of it.

Keith removed his lips from Lance, making a pop noise as he did so. His throat was already sore from the tenacious way he'd let the cock ram the back of it, and his lips were pinker and more puffy than usually. It only added to his sexiness as far as Lance was concerned.

" Fuck me..." The omega murmured, and his voice was raspy. He looked at Lance with pleading eyes.

" What's the magic word?" Lance whispered, wanting to drag it out. He wanted to know that his boyfriend was willing to beg for him. To beg for his cock.

Keith was stumped for a short while.

" Please?" He said, but it came out sounding like a breathy question. Even in the hormone driven state Keith was in, he was aware that they had to be quiet. Not just for the boys, but Ronny was in the next room. If she really was a lesbian or something, this was probably one of the last things she wanted to hear.

" That's right." Lance smirked. The light that shone in his eyes illuminated the murky fog that had shaded over their brilliant blue. Oh yeah. The lust was taking over him, and it was obvious as Keith gazed into them.

Lance took Keith, and gently laid him back into his rightful position; beneath him. He wasted no time before taking off his work shirt, tossing it to the side. It wasn't long after that when he kissed Keith passionately. That alone was enough to make the omega shiver, but Lance was nowhere near being done with him yet.

Keith could feel his member twitching in the thin fabric of the lingerie. He tried to ignore it as he kissed Lance back, but he was soon distracted by a spark of pleasure. Lance was twiddling one of his very swollen nipples in his thumb and index finger, and Keith was instantly whimpering from the sensation. It pretty much rippled across his chest, and sent chills racing down his spine.

" L-Lance..." Keith gasped in his boyfriend's ear, breaking the kiss.

Lance smirked while pinching it somewhat, causing the other to yelp. It wasn't really a yelp of distress or discomfort. Keith definitely liked it, and Lance knew what he was going to do. And that's why he placed a hand over his omega's mouth.

This was completely experimental, but he wanted to know just how sensitive Keith's nipples were. So he started nipping at one with his teeth, lightly biting it's pink surface. That made Keith tremble and mewl into his hand, but Lance wanted more. He moved to full on suck, and that action made him thankful that he was covering the boy's mouth. Keith otherwise would've woken everyone up with a blaring cry.

" You like that?" Lance asked in a deep voice. It almost seemed like Keith was having a seizure from how fast he nodded his head. It was satisfying beyond the point of words, watching Keith melt under his touch. He did it more, deciding to give the neglected one some attention. That was sending Keith plummeting over the edge. It felt so damn good that he could barely handle it.

There were muffled words trying to escape from behind Lance's hand, so he pulled it back a little after he was positive that Keith wouldn't be moaning loudly.

" Please..." Keith begged. " You. Now." He didn't even bother trying to formulate sentences.

" Do you want me to prep you?" Lance asked, knowing that it had been a few weeks since they'd done this. His protective alpha side was there for a second, but he went right back to being overpowered by lust when Keith shook his head.

" I'm fine... please..." The smaller boy was pretty much whining from how badly he wanted it. These damn hormone imbalances were making him desperate to say the least.

Lance just kept on thinking about the baby inside of Keith, about how it was there because of him. Instead of fretting about it or anything like that, he was busy looking at it a different way. It was hot, knowing that he was technically always inside of his boyfriend. He got even more turned on while taking off the lingerie and spreading Keith's legs apart. Lucky for Lance, he didn't have to go through the trouble of putting on a condom. His omega was already knocked up, so there was at least one perk in all of it.

The alpha kissed on the delicate skin located on the insides of Keith's thighs, just taking the time to appreciate it. Keith was shaking a little, eager to be filled and stretched out. He needed it right then.

Lance stroked Keith's member, feeling the precum slick his hand with every time he pumped it.

" Lance..." Keith covered his own mouth, giving it his best effort to not make a sound. They'd been here before, and the last time he tried to be quiet, Keith ultimately failed. He treated this like some sort of redemption.

Lance could tell that Keith was getting even more antsy for the good part, and he was as well. Long gone was the exhaustion that he'd felt upon arriving home. This had succeeded in riling Lance up. The adrenaline he felt was enough to keep him wide awake, and ready to pleasure his omega in any way he could.

He lined his length up at Keith's hole, massaging the boy's rim with the head of his cock. Lance could feel the resistance, and the tightness of Keith was reluctant to let him in easily. Even with the slick that was practically oozing from it, Lance had to use a little force to breach his entrance.

Keith's back immediately arched, and he hissed into his hand from the initial sting. The pain was primarily around his rim due to the overwhelming stretch.

Lance's eyes widened as he heard the noise Keith made. His instincts yet again flip flopped from lustful to protective.

" Babe, are you okay?! Do you need me to stop?" He asked frantically, almost moving to pull out. But Keith locked his legs behind Lance so he couldn't.

" N-no... don't stop." Keith's eyes cemented shut as he tried to ignore the ache emanating from his lower half. He just would need a bit to get used to this. It was a combination of the time since they'd done this, as well as his hypersensitive nerves that made it difficult. Pregnancy had changed the way he handled many different sensations.

Lance's ears hated the way Keith was whimpering, the sound he was making from discomfort. His pregnant boyfriend was experiencing pain, and that was enough to set off his paternal, protective, and alpha instincts. It was complicated as fuck. He wanted to stop, but at the same time, he wanted to make Keith cum to make up for it.

Keith tried to focus on his breathing, making sure that it stayed steady. With the pleasure that was beginning to stem from his hole, he had to be aware of his volume as well.

It was a little while later before Keith felt minimal pain.

" Go..." Keith's request was muddled from behind his palm. Lance could still understand him, but he didn't just slam his hips in response. He was going to go easier on Keith despite what his dominant urges were.

Lance brought his hips back, and Keith let his legs drop so he could. It was only a second or two later when Lance's member was sinking back into the inviting heat of Keith's hole. It started off painstakingly slow, but it worked into a more steady pace eventually.

Keith was clinging onto his silence with no room for error. There would most likely be a red handprint over his mouth from how hard he was trying.

The pressure surrounding Lance's cock was almost enough to drive him insane. He was so tempted to just slam Keith until he was screaming for dear life and clawing his back to shreds. But he didn't. Lust and his more concerned side were tussling for control, and right then, lust was losing.

The alpha leaned down, continuing to thrust his hips but at more of an angle. He wrapped an arm around Keith firmly, borderline sensually kissing his neck.

" Hnnngh-" Keith whined loudly but it was muffled. He couldn't get enough of Lance right then. The long sought after sensation he felt was making him tremble with pleasure.

" You okay?" Lance asked, nibbling at Keith's bite mark. His instincts were a confusing, bipolar mess.

" Mhmm!" Keith tried to answer, but it just sounded like a loud moan from behind his hand.

Lance was panting somewhat as he passionately drove in a little deeper. Every thrust was going to that one specific spot, the one that could make Keith's eyes roll back in ecstasy.

Don't get Keith wrong, he loved being treated like Lance's toy, loved it when he called him names and spanked him and all that. But he was happy that they were going a little slower this time. Even though he'd felt the need to be drilled, it would've been too much too fast and Keith now realized it. This was plenty.

The more he repeatedly moved his hips, the harder it was for Lance to control himself. He wasn't exactly gentle with Keith, but he wasn't ramming him into the sheets either. It was a sort of happy medium that resulted from his instinctual dispute.

" Fuck..." Lance breathed down Keith's neck, making him get goosebumps everywhere.

Keith finally was able to open his eyes, and he saw Lance over him. It was nearly as hot as the way he whispered in his ear. He took his hand away for a second, trying to say something without moaning loudly.

" C-cum inside." The omega managed to stutter before having to slam a hand over his mouth to keep from waking everyone up.

At the mention of that word, Lance realized that he was already close to his climax. He was so wrapped up in containing himself that he hadn't noticed the pressure building up in his abdomen.

The alpha began losing his grip, going a little faster during his chase for his looming orgasm.

" L-Lance!" Keith ended up crying out when his hand slipped. Lance's eyes widened, and he moved to cover his omega's mouth himself.

Keith soon came all over both of their chests, and his scream was thankfully covered for the most part.

That was it. Lance was at his limit. The fact that Keith was making all those noises because of him, cumming because of his cock... it pushed him over the edge.

He filled his boyfriend to the brim with sticky, white-ish colored release. Damn. This was the best orgasm Lance had experienced in a long time. It felt ten times better without his length being caged up in a layer of rubber. It was also way more satisfying to see Keith taking his load, watching it leak from the boy's hole as he eventually pulled out.

Keith panted, whining a final time as Lance unburied his cock from his hole.

The alpha moved off to Keith's side, holding him close and not caring that they were both sweaty.

" You're so good..." Lance mumbled, nuzzling into the smaller boy's neck. He was thankful that they'd successfully avoided waking the twins up. If they'd been too loud, there would be a ruckus and stampeding down the hallways.

Keith felt himself being pulled more into Lance's chest, and he couldn't have been more happy about it.

" I love you..." The omega whispered. It was a weird time to be thinking about it, but Lance was going to be an amazing father to their child. Keith knew that much already.

" I love you more."

" Sap." Keith chuckled. And he sat up somewhat. " I've gotta shower."

" Mind if I join you~" Lance cooed after him. And Keith was feeling numbness and tingling around his rim as he walked.

" Not at all."

(( One more thing. Guys. I wrote the first book before the announcement about Shiro was made. And I'm not saying this because I'm trying to force Shallura or whatever -I lowkey already like Shadam better- but as far as I know... Shiro hasn't been confirmed GAY. Someone can date a guy and be bisexual or pansexual or something else. I'm not trying to stir up anything, but I really don't like it when people assume sexualities. Okay? I'm just going with the fact that Shiro isn't straight.))
