"... Sans?"

He jumped in his seat, scrambling, sitting up straight and slamming shut the book he'd had open in front of him. He blinked multiple times up at you, the light seeping in through the windows making him squint a little.

"wha? what? ... what time is it?"

You glanced at his hands which were... not-so-subtly covering the book he'd been reading. He noticed your line of sight, and the book (plus another two on the floor and a bunch of papers) all vanished from sight instantly.

...

"Sans, you've been... you've been acting super weird." You pursed your lips, taking in his shadowed, droopy eye sockets and funky smell.

He was silent for a few moments, but only a few, staring at the spot where the book had previously been that now empty. He sighed, rubbing his sockets with the heels of his palms, making a weird unintelligible groaning sound under his breath and sinking deeper into his chair.

You raised an eyebrow, looking at the scattered papers, and slowly closed the turned-off laptop on the desk.

"You only got 83 on your exam, Sans." You couldn't believe you were saying that like it was something to be worried about. "You're up all night all the time doing weird... 'research', and you won't even let me look at the books. Is something going on? You know you can talk to me, right?"

He sat up a little and turned to you, mouth opening, eyelights small and tired, and for a moment it was like he was going to tell you.

But... he seemed to change his mind as the first word was about to leave his mouth, and instead...

He groaned. And slammed his head onto the desk, with a hollow thud.

... You had to take a small breath to calm yourself.

"...So." You said, voice shaking just a little. "You can know everything there is to know about me, but I'm not allowed to see what kind of books you're reading?"

"it's... not that simple," he said, face still on the desk. You saw the sweat dripping off his skull, his closed off demeanor... and it just made more worry bubble up underneath the frustration.

"Sans, baby, just... you can talk to me." You reiterated, trying to sound more comforting than exasperated, crouching down a little and gently cupping his skull by the mandibles and turning his head to face you. He seemed to uncoil slightly at the contact, a tiny purr escaping from between his teeth and his sockets lidding a little. He just looked so tired... "Come on, you stalked me for God knows how long. Is there really anything you can tell me that would shock me more than that?"

"yes," he said, immediately, eyelights small and dull, with a resounding breath out. "and i don't even know if it'll be the good or bad kind of shock."

... Fuck.

Well. Now you were super interested.

Surely there's nothing more shocking than your crush, the person you admire most, idolised, made perfect in your mind and would throw yourself off a bridge to be with, revealing himself to be a stalker with a serious and downright worrying obsession with you, an inability to let go of anything in his life that gives him happiness in case it never came back and needing to have control over everything to feel safe and secure.

You sighed. Unfortunately, experience had taught you that there was no way you'd be able to get him to talk if the "You can talk to me" emotional bombshell didn't work.

"Just..." You sighed again. "Just remember that I love you, alright? You'll tell me when you're ready."

He froze, and then smiled weakly, little... little tears falling out the corners of his sockets.

... Daw. Your heart ached, mood softening.

"... 'lright." He took a small breath and sat up a little, placing his forehead against yours, closing his sockets. Sometimes you forgot just how much hearing that meant to him. He might be completely mentally fucked up and all kinds of crazy, but he really did love you. "love you too."

You let him rest there for a few seconds, leaning on you with shut eyes, and once his breathing evened out and you knew he was asleep you carefully extracted yourself and let him lean on his desk.

Dumbass. He could sleep literally anywhere.

But you were concerned, even as you got a pillow for his head and put a blanket over his shoulders, letting him rest. Whatever this thing was that he was researching... it...

... Well, it was really taking a toll on him. You stood there for a moment, rubbing a hand absentmindedly over his back and looking at his exhausted, sleeping face. Usually he was always bright and happy and teasing and funny and completely conscious despite doing all his coursework AND some of yours with little to no sleep sometimes (you assumed that maybe the power of love or pure positivity and happiness kept him going). But this... this thing he was so obsessed with researching was weighing far too heavy on him.

You wished he'd tell you.

You eventually gave him a gentle pat on the back and headed off to sit down somewhere instead of standing awkwardly at a sleeping dude's side.

You leant against your own desk, staring out of the window. It was raining outside, grey mizzle/drizzle tapping against the small window and wind whistling in high-pitched tones over the top in a badly orchestrated song. The dull, dreariness of it matched your mood perfectly (pathetic fallacy at it's finest); you'd been feeling weird and kinda sick this past week, not to mention your breasts feeling super sore. Staring out of a misty drizzly window was... almost comforting? Like the weather was feeling just as shit as you were.

You started... thinking, brows creasing a little, while staring at the tiny droplets gathering and falling and swirling on the glass, each one containing a tiny flipped world of mirrored light.

You thought about Sans's behaviour, trying to see if there were any dots you could connect.

You completely disregarded the first thought that popped into your head- that he was cheating. Because seriously? He'd probably kill himself.

And you were being unironic.

Besides, he only seemed to get more growly and protective and obsessive as time went on. About a week ago, he'd nearly ripped out someone's jugular for bumping into you as you passed them. Usually he just gave a few angry glares or death threats if he was in a bad mood... but you'd had to physically restrain him last time. Fuck, it'd been like trying to talk to a dog with rabies. He'd been absolutely manic .

Speaking of dogs, he'd started acting like one, too. Doing weird snuffly things and licking your neck (more than normal). He really enjoyed running his hand over the skin of your stomach while you slept, a little constant growly purr in his throat.

So, was he just... in a really fucking bad mood? But that didn't explain his secrecy. And why would he get more protective if he was cheating? Surely he'd grow distant? None of it made sense, and you sighed, finishing your coffee.

Oh well. Hopefully he'd tell you. That always seemed to happen- you'd think you'd finally gotten to grips with how creepy he could be and then NOPE, he'd admit to having a stack of your old panties hidden under the bed that he'd been keeping. Like, what did he even do with them? Sniff them?

... Actually you wouldn't be surprised if that was what he was doing with them.

---

You were lying in bed together when it happened.

Light was no longer coming in through the curtains, now only darkness remained outside, the rain still tap-tap-tapping on the window quietly.

You yawned- Sans was spooning you gently, doing his weird tummy-rub thing. Another important thing about Sans- he was never the little spoon. Ever. He was either cuddling you, or cuddling you. No in-between, no escape.

"Hey, Sans..." You yawned again, and wiped the tears from your eyes when you stopped. "When's my next period due? I forgot."

Usually, he'd jump in with the exact date, maybe even with a rough estimate of what time as well. Based on which girls you hung out with in class or how much time you spent away from his company (very little), your period would shift a little, but he somehow always knew.

...

"... Sans? Are you asleep?"

... He took a deep breath.

"... you aren't gonna be getting periods for a while now, baby."

"Uh..." You paused. "What?"

He kept stroking your stomach.

"i-i did some research, and..." He buried his face in the back of your head. "i... i think you're pregnant?"

You deadpanned. Suddenly, your tummy felt weird.

" What ."

"no, scratch that, i know you're pregnant." He seemed to be trying to hold you even tighter, without actually tightening his grip. "why do you think i've been acting like this? i've been so overprotective, even for me ... fuck, i can smell the damn change in your pheromones. at first i just thought i was being weird but now i think it's because my instincts are telling me to protect you and the baby."

"You. Got me. Pregnant ." You said, hoping that if you said it slowly you'd come to grips with what the fuck he was saying. You didn't know how to react. Didn't people cry with joy when this happened? You felt like crying, but you had no idea whether or not what you were feeling was good or bad. "In college. "

He cringed. "yeah, uh..."

"Sans, you..." You took a second to compose yourself, your throat hurting from holding back tears. "You understand we can't keep it , right?" You rolled over to look at him, feeling sick. There was a baby inside you . Right now. A living creature. How long had it been there? God, it was so daunting. Fuck, what if you'd eaten something bad, and hurt it...

He blinked. "wait, what?" His face fell. "w-why not?"

Your hand joined his on your stomach, still flat at the moment. "We can't give it a good life. Sans, I'm in college. How... how do you think everyone's going to react? How am I going to look after a child and do my work at the same time? We don't even have a proper house..."

"you're saying that assuming that you're the one who's going to be doing all the looking after."

You blinked and looked up at him, shocked.

"... What?"

"you humans have this weird thing about the mom always being the one who has to do at the work." His eyelights were soft, but there was an element of sternness behind them. "can you seriously tell me i'd let them out of my fucking sight?"

"But... we can't afford a kid." You felt tears in the corners of your eyes. "And... all my work? I can't look after a child AND do all the stuff I'm doing... I'm already too damn stressed. I don't want to neglect it."

"pfft. what did i just say?" He chuckled. "i can look after them."

You gave him a look.

"Sans, you already study enough to put rocket scientists to shame, track my every body function, clean pretty much everything, and cook almost every night. How the hell are you going to fit baby time in?"

"magic." He grinned, booping your nose, and you chuckled, but sighed, rubbing your eyes.

"How... how long have I been pregnant?" You asked, some tears slipping free.

"hm..." His hand started rubbing circles again. "... i'd say about two weeks, at most. so we've got time to think it over."

"I need to look up how late in a pregnancy you can abort a child." You said, but even as you spoke the words, you knew that that wasn't what you wanted. You knew you wanted to keep it. But... you didn't want to raise a child with a miserable life. You didn't want to force it to live in a world where you couldn't afford to send it to school.

" you're not aborting my baby ." Sans's voice was low, and possessive, and with a roll that resembled a growl. You felt a surge of panic and your head snapped up to make eye contact, but he instantly backpedaled.

"i-i mean, unless you actually want to..." He started sweating, and the hand that wasn't rubbing your stomach came up to the side of your face. "sorry, it just... came out. i didn't mean it. you're gonna have to go through labour and emotional garbage everything so if you really, really don't want it, we can just try again for another one once you finish college, right?"

You stared at his face, his concern and badly hidden excitement, and...

"Oh my God..." You said, covering your mouth with your hands. It only just started to weigh down on you. "I'm... pregnant. "

You were so confused. You didn't know whether or not you wanted to lie there and cry or jump out of bed and start running in circles, and plan a party or something. What were you gonna name it? Was it a girl or a boy!? You were going to be a mom .

"F-fuck, Sans, I'm..." You were crying, and you tried to cup his face, but your hands were shaking so badly, you just had to grip the top of his shirt. " I'm pregnant! "

"i know." He said, and he was crying too, grinning. "i know, baby. you're gonna be such a great mama."

You practically tackled him in a hug, so overwhelmed you couldn't speak anymore. It was just babbling. Shit, if someone had told you back when you'd gotten your first text from him that you'd have a fucking baby with him, you would've packed up and moved to another country. But here you were, with Sans.

"i promise, we're gonna be the best goddamn parents." He started running his phalanges through your hair again, chest shaking with every inhale. "god, i'm so happy. you make me so happy. i can't... i can't even... fuck ." He started laughing, and you joined in, then moved and pressed your mouth to his, desperate and happy and sad and a parent .

He kissed back, and even though it was kinda wet from the tears, it was probably the best kiss he'd ever given you. You could feel all his hopes and dreams and fears and joy and sadness, from the way he was gripping your hair and holding you tight to the way his tongue moved against yours.

When you finally broke away, you stared deep into his eye sockets, and...

...

"Hang on! You said monsters couldn't get humans pregnant!"

...

Sans looked away, chuckling nervously. "well... i thought so too. otherwise i probably would've used a lot more condoms."

That made you snicker, and now that the crushing wave of mixed emotions had all but passed, you just felt... light. Excited. There was a child inside you! Wait, would they be a skeleton in the womb? Would they even be a skeleton!? You gasped. A little baby-sized Sans, oh man!

"we're gonna have to talk to alphys or something." He tucked a loose strand of hair behind your ear. "i don't know jack about monster pregnancies, and i need to check if it's safe for you. might be some magical weirdness that i don't know about."

"Sans." You said, cupping his cheek. "We'll be fine. Well, actually, we probably won't, but I can guarantee we'll get through it. You wanna know why?"

He blinked. "why?"

"'Cause I got you protecting me." You kissed his forehead. "Means I can sleep sounder. Knowing that daddy Sans is looking after us."

A blush started spreading on his cheekbones, smile twisting at the edges.

"you can call me that more often."

"Sans, I'm trying to have an emotional moment with you." You raised your eyebrows.

"hey... does this mean no sex for 9 months?"

You blinked, pursing your lips. "Uh... I dunno. I'll... have to look it up tomorrow."

"mmm... that's too bad." He purred, rolling so that he was on top of you. "i was really hoping to have some fun tonight..."

You looked up at him, a blush creeping up on your face. "I dunno... uh... Google it maybe? Or call Alphys?"

He sighed, and kissed your forehead, before rolling off you again and leaving to go get his laptop in the other room. He came back in the room and laid beside you, turning it on.

You laid your head on his shoulder, subconsciously rubbing your stomach. Sans pulled up the web browser and literally Googled "can you have sex while you're pregnant?" and you bit your lip to keep from laughing.

He clicked on one of the links scrolled down a little... and read aloud.

"no, a baby isn't hurt when a pregnant woman and her partner make love. the amniotic sac and the strong muscles of the uterus protect the baby, and the thick mucus plug that seals the cervix helps guard against infection. during intercourse, the penis doesn't go beyond the vagina, so it won't reach the baby." Once he was done he looked over to you with a cheeky smile.

You giggled, rolling your eyes a little. "You're so... I don't know. You always want sex. You're like a male nympho. A horn dog."

He laughed shortly. "can't help it... " he started, putting the laptop on the floor, "you're just so... you."

"Me?"

He rolled back on top of you and kissed you gently. "yeah... you're warm, and soft, and squishy..." He gently squeezed the skin on your sides, making you shiver pleasantly. His voice had taken on that tone that made your heart hammer inside you. "i love everything about you. the way you feel... taste... smell. you're just so great."

You felt like your face was on fire. He always made you feel so weak... in the worst and best ways. "Sans..."

He smiled and leaned down to kiss your neck. "you make me so happy, baby girl."

You let out a tiny noise, sighed, and gently pushed him off, pressing your hands on his chest and trying to put out the heat inside you. He looked at you, confusion clear on his face. "what?"

"...No sex."

He looked crestfallen. "whaaaaat?"

"...It might be... different for an interspecies couple... I wanna wait to ask a doctor, or Alphys or something..."

He groaned softly and laid his head down on your chest. You rolled your eyes again, petting him.

"Don't be such a baby."

He silently kissed in between your breasts and then started to go downwards. God dammit.

"Sans, no."

"sans yes." He purred back, occupying himself with peppering your stomach gentle kisses. You whined and he looked up at you. "c'mon princess... this can't hurt the baby."

You groaned, covering your face, trying to act like you were hard done to instead of just really wanting him to eat you out. "Fine. Be gentle."

"i always am... except for when you want it rough," he teased.

... "OhmygodIhateyou." You said in one breath, trying not to laugh.

"you love me, don't lie."

You didn't say anything. Just watched as he started to unbutton your jeans. He always acted like he was addicted to you or something. He was so insatiable, it was ridiculous.
