Chapter Text
the signs were there when all three of his friends, lana, lois and chloe had told him he smelled different.
"you turn 18 and the first thing you do is get yourself knocked up ? what about playing football at Met U ?" lois had cackled and the rest of his friends laughed.
"but seriously, clark. i think you should get yourself checked out" lana had told him kindly with a concerned touch on his shoulder.
"our boy here hides a lot of secrets" chloe coughed into her hand as if that helped his little predicament. he should not have mentioned to them about feeling fatigued as of late and the random bouts of nausea if this was how they were going to connect the dots.
clark had rolled his eyes and continued drinking his coffee, not noticing lana's gaze on him still.
another major sign was when his latest heat presented differently. less of that sticky cloying feeling of wanting to get fucked. his emotions were on high and he wanted to be near lex all the time. thankfully, lex had still found him irresistible because of his changing smell. the way lex pounced on him solved his issue of presenting as clingy because their relationship wasn't exactly on par with the level of need clark had.
they had first fallen into bed with each other when clark had shown up at the luthor mansion on his 18th birthday, adamant to confess his crush on lex who had also nursed an equally devastating crush on him, unable to confess as a result of their unbecoming age gap. "i'm not a kid anymore" clark had said before kissing a surprised lex. lex had sighed against his lips but still gathered him in his arms, kissing him back till they were both breathless. lex more than clark but the way his heart was beating, clark couldn't have felt more human than that very moment.
lex had wanted to take his time with clark who was still relatively inexperienced. but clark had a wish that he wanted fulfiled, never having been in a relationship and he had indulged him as expected.
during his break before college, they had went on road trips where lex could kiss him freely under the shade of huge silver maple trees and skinny-dip in lakes where no one could stumble upon them. lex hadn't batted an eye at his unique alien genitalia which made for a pleased clark, happy to have his virginity finally taken by lex luthor.
"it just means i can fuck you without prep" lex had replied with a breathless awe before taking him at the back of clark's truck. clark had been fucked within an inch of his life, moaning abashedly with only the clear blue sky as witness while lex pounded him with the desire he had been harbouring for years. afterwards, lex had neatly arranged the curls that had fallen in disarray on his head while gently holding his flushed face with the utmost affection.
with college starting in a week, he had concerns about how they were going to make time for each other in the coming weeks but lex was proving to be too distracting on the day he had visited him.
lex had him in bed, arms tightly wrapped around his midsection so that he couldn't leave. clark had laughed and given up, nuzzling his shoulder.
"scent me" clark asked sweetly and lex had rubbed his nose into his scent gland. it was so comforting and it felt like everything that clark wanted at the moment. "you've been very touchy this heat and you smell different. is everything okay ?" lex had asked.
"what do i smell like ?" clark had asked teasingly, not wanting to broach the topic of his sickness.
"you just smell full. bred full" lex had whispered the last two words.
clark had giggled into his neck. then he had put his hand into lex's pants, getting ahold of his cock. he caressed the head of his cock with a teasing thumb.
"want to breed me again ?" clark had asked like the complete fool that he was. of course, lex didn't pass up on the opportunity.
now, he was clutching a home pregnancy test in his hands that was showing a plus sign on the little plastic screen.
he didn't think kryptonians could get pregnant by humans. based on this logic, they had been sleeping with each other without consistent protection.
when lex had condoms, he used them but if they found each other wanting without any protection available, they went without it.
lex hadn't pressed the issue either, considering clark's embarrassment towards his own genitalia. maybe lex had assumed that clark was on birth-control. if only there was birth control for a kryptonian..
more importantly, he didn't even know that clark was from krypton.
when he stood up to wash his hands, he could see that his skin was glowing and his locks of hair looked impossibly soft in the mirror. he pressed his lips together in embarrassment but there was also a shy blush that took over his face. he couldn't believe he had a child growing inside of him. lex had always talked about having a family one day which coincided perfectly with clark's dream as well.
he put the remaining used pregnancy tests which had all shown positive into a bag so that he could dispose of it right away.
clark decided to head to the fortress, fighting the nausea that was steadily rising in him caused by the use of his super-speed. he had to walk the last 500 metres because he couldn't handle it anymore. he ended up grabbing onto some of the icy structures that were at the entrance of the fortress to stop the spinning inside him.
when he finally mustered his energy to walk into the fortress, there was complete silence. he sighed, looking up to the place where jor-el's voice usually came from.
"jor-el, what's happening to me ?"
"clark .. you are with child"
clark sucked in a breath. the artificial intelligence that replicated his kryptonian father never cut to the chase. his whole thing was beating around the bush before clark lost his patience and then, he would smugly lecture his son on whatever was the matter.
"how far along am i ?" his voice was very quiet and it shook with the weight of his truth.
"you're 8 weeks pregnant which means you've been pregnant for 2 months"
"how can you tell ?"
"clark, only your mother chose to get pregnant in the old-fashioned way. most kryptonians used technology for procreation because childbirth was dangerous and harmful to omega's bodies" jor-el had to take a moment here, presumably because he was overwhelmed with the emotions of recalling his dead wife. "i remember how her scent changed when she got pregnant with you"
"let's do a scan" clark didn't trust the nostalgic version of events that jor-el was telling him.
a sphere materialised in front of him, floating in air. he grabbed onto the cool ball of glass.
"press it on your lower belly" jor-el ordered. clark did as he was told and the sound of a strong rapid heartbeat filled his ears. it sounded like the ultrasound scan that his mom had done long before she had miscarried from the shockwave caused by clark's spaceship in the garage.
it was the sound of his baby. alive and kicking in his belly. he pulled the sphere away from his belly, letting silence fill the cavernous space once again.
"you already know who the father is, i presume"
clark didn't reply to jor-el's obvious needling of him.
"are you choosing to keep it ?"
"yes" the answer came instantly. clark gaped in the direction of jor-el's voice. not even a minute had passed after hearing the sound of his baby's heartbeat and now his artificial intelligent father was asking him if he was keeping the baby.
clark threw the sphere at the wall but the wall absorbed it, not allowing him the satisfaction of breaking something in his anger.
"prepare yourself, son. a kryptonian pregnancy is highly similar to the human one. when you are ready to give birth, return here as soon as possible"
