Chapter Text
Kouyou remembered wondering if things would feel as good without the aphrodisiac… He didn’t have to wait long to find out.
He woke up from his post sex nap to the feeling of the tentacles moving against his backside. It wasn’t as disturbing the second time, and before he knew it, the appendages were sneaking their way between his thighs to play with his soft cock.
Kouyou shifted, pressing back against Yuu’s inhumanly warm body. It wasn’t a bad feeling, but he wasn’t sure he was ready for another round so soon.
One of the tentacles slipped across the oversensitive head of his cock and he hissed, body jerking.
“Stop it,” he whined, just a second away from elbowing Yuu in the stomach, but then the Sayaran actually smacked his lips and burrowed closer, his hand twitching on Kouyou’s full belly.
Wait.
“Are… are you actually sleeping?” he whispered incredulously, biting back a moan, because things were getting heated down there.
Yuu didn’t reply, and when Kouyou twisted his neck to look… Yup. The Sayaran was sound asleep, his long lashes casting soft shadows on his cheeks.
What the hell?
Kouyou tried to inch away, to put a bit of distance between them, but - of course - that only made Yuu pull him closer, like he couldn’t bear not touching him, even in his sleep.
Maybe he should just wake him up…
Before Kouyou could utter a word, one of the tentacles found his hole and delved inside easily - he was still wet and open from before. Fuck. Fuck that felt… good.
Kouyou bit his lip and let it happen, not really understanding why. But. But there was something flattering in the fact that apparently Yuu’s body reacted to him, even when the man wasn’t aware of it.
There was another tentacle at his hole, not even trying to enter, just circling around and around, massaging his rim slowly, it was driving him mad. Kouyou actually had to reach down, and push a few away that seemed set on getting him hard. To his surprise, the tentacles retreated, caressing the back of his hand as they went, like an apology.
He would have to ask Yuu about this later, ‘cause it was a little freaky.
Still. He didn’t try to pull away again. The weight of the Sayaran’s hand against his stomach was warm and comforting, and made things a lot less scary.
Finally, the second tentacle entered him. It was a bit thicker than the first, and it reached deeper. He couldn’t remember any of them going that deep the first time. Kouyou could barely do more than pant, turning his head into his pillow. Fuck. That felt good.
The tentacles inside him moved slowly, wiggling around and rubbing his walls. He couldn’t say for sure, but Kouyou thought that there was a lot less urgency in their movements, like they just wanted to explore and make him feel good.
Sayarans were weird as hell.
Still, he let them.
It didn’t take long for one of the tentacles to find his prostate, bumping into it accidentally for the first time, but as soon as Kouyou jerked - his hole clenching down from the shock of pleasure - it returned with a purpose.
Soon, he was reduced to moaning and shaking in Yuu’s arms as the tentacles pleasured him. There was no better word for; they didn’t seem to have any other aim than to make him all shivery and hot with it.
His cock was getting hard - slow but steady - and the other tentacles returned too, wrapping around his erection, keeping their touch light, just a whisper across his sensitive skin. Kouyou was dripping precome from how good it was…
He came like that, mindless with pleasure between the appendages moving in and on him, his orgasm weaker than the first, but hot and somehow comforting.
***
The next time he woke up, Yuu was already awake, getting dressed beside the bed. Kouyou thought that it was a shame to cover up all that beautiful skin.
“Hey.”
As soon as the Sayaran turned around, pinning him in place with those amazing eyes, he lost most of his confidence. What would happen now? Did they just… He didn’t know what to think. Sure, Yuu said things after they fucked, but Kouyou wasn’t naive enough to believe everything men said after sex.
“Hello, my little human,” Yuu said, and just like that Kouyou calmed down. He’d only heard the… the endearment a few times, but it was already making things just a little brighter around him.
“Where are you going? And also, your… junk kind of did the dirty with me again when you were sleeping,” he admitted, feeling his face turn red.
Yuu looked almost adorably perplexed.
“My… junk did the… dirty ?”
Kouyou snorted out a laugh, stretching his aching muscles on the silky sheets.
“Sorry. Your tentacles had sex with me. Again.”
Yuu’s eyebrows climbed up his forehead, like he still didn’t understand and then he must have because his face turned apologetic, fuchsia eyes wide.
“I… I’m so sorry! That… that doesn’t usually happen! I would have… Are you alright, my little human?” he asked, climbing back on the bed and running his large, warm hands over Kouyou’s arms like he was trying to comfort him.
“Hey, hey it’s okay! Well, it was a little surprising, to be honest, but they didn’t hurt me or anything…” he said, not wanting to go into too much detail after it became apparent that Yuu really had no idea it ever happened.
Maybe he should have just stayed silent.
Yuu still looked worried.
“Let me check,” he said, easily turning Kouyou to his side, ignoring his yelp of indignation. His fingers were light as they prodded at his hole, and he had to bat him away, rolling to his back again, because really?
“Hey! No touching! I can tell when I’m hurt, okay?” he said, not appreciating being treated like an invalid. Yuu looked confused, but backed off.
“I’m sorry, little human,” he said, holding his hands up. Suddenly Kouyou became acutely aware of how naked he was compared to the dressed Sayaran. He pulled the sheets over himself.
“It’s fine.”
It wasn’t, but he had a feeling that he would have to get used to all sorts of… cultural differences in the next few weeks.
“Where are you going?” he asked again, watching Yuu get up and zip his uniform all the way.
“I have some official matters to handle,” he said. “I didn’t know if you would come, but I will make myself free from now on,” he promised. Kouyou nodded.
“Right. Is there a place here where I can get some food?” he was starting to get hungry, despite having a big - hangover curing - breakfast.
Yuu nodded.
“I will get it for you. Please don’t leave the room,” he said, and just like that he was out the door.
***
It didn’t take long for Kouyou to grow restless. He got out of the bed and explored Yuu’s room, finding the bathroom on the second try. He took a quick shower. The Sayaran controls were different, but he managed to find the perfect combination of hot and cold water in no time.
The shower was relaxing, even giving him a few quiet moments to freak out over the small bulge of his belly. It didn’t look more than the result of a very, very big dinner for now, but he had a feeling it wouldn’t stay that way for too long.
Fuck, he was pregnant . Kouyou had no idea what to do with that information. On one hand, it was terrifying, even if - as Yuu said - he wouldn’t have to raise the babies, it was still huge.
On the other… a small part of him was… excited to do this for or more importantly with Yuu. He wasn’t sure. They didn’t know each-other long enough for those kinds of feelings, did they?
He went back to the bedroom, looking around to find something to do. There were no books anywhere, and nothing he could identify as a tv either…
Kouyou walked around with only a towel around his waist. One of the walls was… suspiciously bare. The others all had shelves or compartments to put stuff, but this one didn’t. He wanted to feel around it, hoping to find some sort of switch, but as soon as his fingers touched the smooth surface, the whole thing came to life, lighting up and displaying a row of symbols he couldn’t understand.
A voice said something overhead - it sounded just as melodious, but a bit higher than Yuu’s - it was speaking in Sayaran.
“Fuck…” Kouyou muttered, sure that he messed something up. Damn, all he needed was to accidentally launch the whole ship into orbit. As soon as he swore the light of the screen dimmed and the voice shut up. What the hell?
It only took a second for it to speak again.
“ Human interface loading, ” she said, because in English the voice sounded a lot more feminine.
Kouyou blinked in confusion, but the voice was right, and as the light came back on, the menu on the screen was in perfect English.
Wow.
There were three choices; Entertainment, Communication and Education.
“ Welcome to the Sayaran Embassy, please choose an option. ”
Kouyou bit his lip, his hand unconsciously going to his stomach.
He touched Education, because why the hell not?
***
By the time Yuu was back Kouyou had watched a lot of videos, and felt like he was understanding things a bit better. Thankfully the program had audio search, the AI helpfully pulling up things he was asking about.
“Hey,” he said, not even turning around as a documentary about the Sayaran home planet was finishing.
“Hello,” Yuu said, sounding a bit surprised. “You have learned the system.”
Kouyou got up, lifting an eyebrow.
“Yeah? It’s not exactly rocket science,” he pointed out, making the man’s face turn apologetic. Again.
“I’m sorry, my little human, I did not mean to insult you,” he said, holding out the tray he was carrying.
Kouyou wasn’t really offended, and there was food, so he quickly walked over, snatching it from Yuu. It was loaded with the good stuff; fruit, pastries, cheese and bite sized sandwiches.
“So, you all done?” he asked, mouth already full as he sat down on the bed. Yuu smiled a bit, the corner of his lips just twitching upwards like he couldn’t help it.
“Yes. There shall be no more business for me for the upcoming weeks,” he said, sitting down beside him. Their sides pressed together, and even though Kouyou didn’t notice anything missing before, he immediately relaxed at the contact, like something slotted into place.
“Mhmm. Good. Can you eat any of this stuff?” He wasn’t sure about the Sayarans diet, he would have look it up when he had the time.
Yuu nodded his head and picked up a small piece of smoked cheese.
“Yes. Meat is not good for us, but we can digest most other things.”
Kouyou nodded, pushing the ‘other things’ to the part of the plate closer to the man. The small sandwiches were pretty damned good, and he already had a few bites of apple.
Yuu hummed under his breath, picking up bits and pieces, but he was mostly just busy watching Kouyou eat. It was a bit creepy, but he was starting to get used to it.
He picked up the next sandwich without looking, expecting ham or turkey or chicken, but when the taste of salmon exploded over his tastebuds Kouyou could practically feel himself turn green.
Yuu was already opening his mouth to ask what was wrong, but by then Kouyou was halfway over to the bathroom, just barely managing to get to the toilet in time.
Fuck.
***
For a few seconds he was wondering why Yuu wasn’t coming after him, but he was too busy throwing up to really care. The next thing he knew, there were people milling around, keeping him steady, and making him drink something when he stopped gagging on nothing.
Whatever it was, it calmed his stomach pretty well. He stumbled out of the bathroom with the help of the unfamiliar Sayarans, and saw that Yuu was still sitting on the side of the bed with the fallen food tray at his feet, and he was getting medical attention too; one of the men stabbing him with something looking like an epipen.
“W-what’s going on?” Kouyou asked weakly. All he wanted was to get over there and make sure that Yuu was okay.
The Sayaran at his elbow gave him a rueful smile.
“I’m afraid the junior ambassador has bonded a bit too well with you,” he said.
What. What the actual hell?
Yuu’s skin wasn’t it’s usual teal, but almost white - and he had no idea Sayarans could even do that.
“Is he okay?” he asked as they slowly made their way over. The man nodded.
“Yes. We are… prone to having a very close connection to our mating partners. Sometimes even symptoms of pregnancy get transferred through the bond.”
Oh. So Yuu was nauseous too? That didn’t explain all the fuss.
Finally he was allowed to sit down beside him, and Kouyou bumped their shoulders together. Yuu looked like shit. Even his eyes were bleached of color, looking pale pink.
“You should just go and get it over with, you will feel better afterwards,” Kouyou told him with the wisdom of too many drunken nights behind him. Yuu just shook his head, pulling him closer.
It was the Sayaran who helped him that explained.
“Our species can’t vomit. We don’t have the muscles needed, and we don’t get nausea. It’s a very alarming feeling for those of us who experience the human ‘morning sickness.’”
Oh.
“What can I do?” he asked, because Yuu wasn’t talking, just sitting there with his eyes clenched tight and his mouth a thin line.
The man patted his shoulder before waving the others out of the room.
“He should be better as soon as you’re back to normal.”
***
The next weeks were challenging. They had to realize that there was a whole array of perfectly normal food stuff that got Kouyou sick - even things he normally loved - which was a bummer. It usually knocked them both out for the whole day.
His belly kept growing. It was gradual enough, but still scary. So much so that some days he just didn’t want to get out of bed, curling up under the covers and just… not dealing with what was happening with his body, and pushing the Sayaran away when he tried to have a little fun. It made Yuu awkward at first; he couldn’t really understand how he felt, since this was a natural part of the Sayaran life cycle. But he didn’t try to wave his worries away. Instead the man would sit beside him, stroking Kouyou’s hair and sing.
He had an amazing voice, the natural melodious tone of the Sayaran language made everything sound like a magic spell, and when Yuu sang, it was otherworldly and amazing. Kouyou could have listened to it for years.
***
He sort of lost count of the days, to be completely honest, but when one morning he woke up to dull pain in his lower stomach, he knew with absolute certainty that it was time.
Yuu was sleeping behind him, holding him close as always, and Kouyou elbowed him in the ribs.
“What?” Yuu asked, sitting up right away. By now he was used to Kouyou getting all kinds of weird cravings and was ready to go at a second’s notice. But this time Kouyou reached back and grabbed his hand blindly, too scared to move.
“I… Fuck, I think it’s staring,” he said, voice high with panic.
Yuu stilled for a second and then lay back, hugging him close. Why wasn’t he calling the medical staff or something.
“Tell me what you are feeling,” he said, sounding way too calm for the situation in Kouyou’s opinion.
“Uh… my stomach, it hurts,” he said. He tried to calm down enough to listen to his body, and as soon as he managed to get his breathing regular again - with the help of Yuu’s gentle hands rubbing up and down his back - he paused.
“Well, it’s. It’s a pressure, I guess. But it’s uncomfortable.”
It didn’t hurt after he managed to relaxed, but intensified when he tensed up. That seemed like it would be a problem.
Yuu nodded against his shoulder.
“That is perfectly normal. We should have sex.”
“What?! This… this is no time for joking!”
Yuu sneaked a hand down to his ass, his long fingers dancing across his crack and making him shiver, even with how scared he was.
“I’m not joking, my little human. It will make everything easier.”
Kouyou moaned. This couldn’t be happening. But… but he trusted Yuu enough to know that he wouldn’t risk getting him hurt just for a fuck, so it had to be true.
He turned on his back carefully, looking up into Yuu’s pretty, fuchsia eyes. Somehow they looked even more vibrant right then.
“Okay… Just…”
He didn’t know what he wanted to say… Please take care of me? It sounded weird even in his own head. Somehow Yuu still understood him perfectly. He leaned down, kissing him slow and deep until Kouyou couldn’t do anything other than hold onto his shoulders.
“Ssh, my little human, all is well,” he said when they parted. Kouyou didn’t even notice the desperate little noises he’d been making.
Yuu parted his legs - careful of his belly - and kneeled between them, his tentacles in a frenzy. Kouyou came to understand that they it was their way to communicate arousal. He reached down and touched the nest of appendages, making Yuu close his eyes in bliss. It was almost like they had a mind of their own, and they immediately twisted around his fingers, rubbing against his skin, leaving it slick.
Kouyou pulled his hand back and reached down. His ass felt open already - maybe it was because of the eggs - but he took a deep breath and decided not to worry about it for now. He used the lubrication covering his fingers to stretch himself.
Yuu kissed his shoulder, his neck… his hands busy on Kouyou’s chest, playing with his nipples, and stroking the heat in his spine that much higher.
Kouyou bit his lip and threw his head back when he was finished. Yuu didn’t wait for an invitation, pushing close and letting his tentacles do the rest of the work.
It was amazing. After so many times it wasn’t weird at all to feel them slither and wiggle into him, pulling at his rim and rubbing against his walls. Kouyou loved it, and when he was awake at night, he thought he might never find a simple cock satisfying again…
“That’s it, my little human, just let me make love to you,” Yuu said, making him melt into the sheets. The Sayaran only recently started using that expression, and every time he did it felt like a caress.
“Yes,” he breathed, locking his ankles behind the man. The only thing he kind of missed from human sex was the thrusting. With Sayarans, the tentacles did all the work, and the rest was barely more than an embrace…
Except - just when he was adjusted - Yuu pulled back and then pushed forward, the friction making Kouyou’s eyes roll back with pleasure.
“F-fuck… What. What are you doing?” he asked on a gasp. Yuu kissed his slack mouth.
“It is advised to provide a bit of… extra stimulation before delivery,” he explained. His teal skin was flushed.
“Is it painful?”
Before he could stop his movements Kouyou shook his head vehemently.
“No! Nope. All good. In favor of ext… extra stimulation.”
It took embarrassingly little after that. With the constant pleasure running along his veins, he almost completely forgot about the rest, the pressure building in his belly melting into heat.
He didn’t think he'd ever came that hard in his entire life, and by the way he almost collapsed on top of him he had a feeling that Yuu thought the same.
“T-that was amazing,” he said, throat dry from too much moaning. Yuu nodded against his shoulder, and then got up with a grunt, pulling out carefully.
It made Kouyou whine. His hole felt absolutely wrecked; open and relaxed.
Yuu bent down and kissed his belly. It wasn’t as big as a human pregnancy but pretty close.
“You are ready, my little human, can you push for me?”
Kouyou shook his head, still basking in the afterglow, but he did try. His eyes snapped open when he felt a mass moving inside him, pushing against his rim from the inside.
Fuck.
It didn’t hurt. It was strange and a bit scary, but when the first egg popped out of him it felt almost… natural. He blinked up at the ceiling, not knowing what to think.
“That’s it. Please try again,” Yuu said, quiet and focused. His hand was rubbing his thighs, and the touch was comforting enough that Kouyou just closed his eyes and did as he was told.
It took surprisingly little effort, though it got harder by the end, his hole too tired, muscles aching from both the fucking and the constant pushing. He didn’t look down, though. He didn’t know if he could face the… the eggs.
Yuu kept talking to him, mostly about soothing nonsense, sometimes even switching into Sayaran, but he always stayed calm and that was enough. That was enough for now.
By the time he managed to force the last egg out he was crying quietly, too overstimulated and exhausted, and not wanting to do anything other than sleep for a thousand years.
Yuu pulled the sheets over him, kissing his forehead.
Kouyou was dimly aware of people coming into the room. Quiet conversation. Some shuffling around.
He just wanted to sleep.
He was worried in the back of his mind that Yuu wouldn’t come back, that he would just disappear as quick as he appeared in his life now that he had what he wanted…
But a few moments later the mattress shifted and the Sayaran’s warm body curled around him from behind, kissing the nape of his neck.
When Yuu started singing under his breath Kouyou finally relaxed. They would be okay.
