[Only for when you feel like it/have time to] The dreaded time of the month has come. Idk what monsters, but their reactions to their s/o going through their monthly period anguish. [I'm way too embarrassed to come off anon, sorry.]
He’s read about this in a human anatomy book, so the first time he comes over and finds you curled up in comfy pajamas, writhing from painful cramps, he isn’t alarmed. Instead, he starts to sweat a little. He also happened to read that this time of the month comes with mood swings.
He treads carefully; this explains why you’ve been much testier than usual about his puns and general shenanigans. He brings you back greasy food from Grillby’s and doesn’t know how to do much more than just let you lie on the couch with your head pillowed in his lap. While he’s a little curious about the details, he wisely decides not to ask you; he’ll just consult the Undernet later.
Papyrus only finds out about this when the Annoying Dog happens to dig through the trash, and welp, this is beyond disgusting but your bloody feminine product has been strewn throughout the bathroom floor for Papyrus to discover.
He does the only logical thing and assumes you’re dying, of course.
“HUMAN! ARE YOU ALL RIGHT?!?! THERE WAS SO MUCH BLOOD EVERYWHERE! ARE YOU HURT?! ARE YOU HIDING THE WOUND! IF YOU SHOW ME, I CAN HELP YOU PROPERLY BANDAGE IT!”
“I’m fine, Papyrus! Geez! It’s normal– it’s just something that happens to women,” you attempt to reassure him through your bright blush. He’s gingerly touching your face, your arms, your sides, carefully looking for any sign of bleeding.
“NORMAL?! IT’S NORMAL FOR HUMANS TO BLEED?! THAT DOESN’T SOUND VERY NORMAL TO ME! YOU DON’T HAVE TO HIDE IT! IF YOU’RE INJURED, I WANT TO HELP YOU!”
The sweetheart looks like he’s on the verge of tears, he’s so concerned. You don’t want to explain it to him, so you just tell him it’s something private and keep reassuring him that everything’s fine. For the rest of the day, he treats you like you’re made of glass and refuses to let you out of his sight.
Sans eventually explains it to him so you don’t have to.
Red realizes that you seem to be more irritable than usual, when he’s teasing you and you happen to bite his head off because dammit, your stomach hurts so much. He scoffs and flippantly says, “what? ya got that weird human period thing goin’ on?”
It’s the wrong thing to say.
Red’s done his research. He understands what it means, but he’s bad about keeping his mouth shut. The two of you end up fighting, he huffs away to his room, and you scowl at the TV and lie on the couch for a while.
Eventually, Red comes in with some Sea Tea and hands it to you wordlessly. Once you drink it, you actually do feel a little better, so he motions for you to sit up. You put your head back in his lap, and he rubs your lower abdomen while you both watch shitty MTT re-runs.
Right now, it’s best that both of you just enjoy it in silence.
(*Someone also sent me a request for the s/o getting their period and staining a couch, but I can’t for the life of me find the ask. Sooo, that couch that gets stained happens to be Edge’s. Enjoy. )
You stand up from watching TV at the Underfell brothers’ house, intent on getting something to drink from the kitchen because man you’re thirsty. As soon as you do, you hear Edge shoot to his feet, his expression filled with concern. “HUMAN, WHO DID THIS TO YOU?!” he snaps, coming to your side. Red’s eyesockets are completely dark, and he starts sweating.
“Did what?” you ask in confusion.
What are they freaking out–
Edge turns you around by the shoulders for a better view, and that’s when you spot the stained couch. Mortification rises to your cheeks. Your gaze locks with Red, and in an instant, he nopes right out of there and shortcuts away.
“Oh god, I’m sorry about the couch. Lemme get something to clean that off!” The words tumble out of your mouth so fast that you’re not even sure it was intelligible.
You attempt to dart away–preferably to the bathroom, even though you’re certain by the way Edge is staring at your ass that your pants are ruined–but Edge catches your arm and turns you to face him again.
His expression is filled with undisguised rage, and his grip is slightly painful. “I’LL KILL WHOEVER HURT YOU, SO TELL ME WHAT HAPPENED!”
“I’m not hurt!”
“LIAR! YOU’RE BLEEDING!”
“That’s just something that happens!”
“NO, IT’S NOT!”
“Yes, it is!”
“WHERE IS THE BLOOD COMING FROM IF IT ISN’T A WOUND?” He leans forward, looking so pissed that you feel indignant anger trump your mortification. You’re already embarrassed as hell; what do you have to lose?
“My vagina, Papyrus! MY VAGINA!”
Shock courses through him, mostly from the fact that you just shouted such a cold, proper term in his face. “YOUR…” He trails off as it starts to click. You can see confusion there, then a darker sense of anger begin to wash over him. “WHO?” The question is bit off and clipped, ground out from between his clenched teeth.
Oh hell, now he thinks…? “No one! It happens every month! It’s natural! It’s a reproductive human thing!”
“OH.” He finally lets go of your arm. He even starts to look a little embarrassed. “I KNEW THAT! I WAS JUST TESTING YOU!”
“Testing me?” You can’t help but give him a hard time.
“YES. AFTER ALL, IF IT’S A MONTHLY THING, YOU SHOULD HAVE BEEN MORE AWARE. I’LL HAVE YOU SCRUB MY COUCH UNTIL THE STAIN’S OUT, AND FROM NOW ON, YOU HAVE TO SIT ON A TOWEL!”
At this point, you don’t even care. You end up wearing Sans’s shorts home to change (after kicking the bottom of his shoe while he laid on his bed and complaining about the fact that he left you down there to deal with that), and by the time you return, the stain is already gone.
Edge does, however, toss you a towel to sit on.
