𖤝—
your boyfriend had already had an exhausting day at work.
from his bandmates messing up the choreos during practice to managers sending them to fansign after fansign, he’d say he’s really got his work cut out for himself—so when he opens the front door silently and hears you whining not even halfway through the doorway, he’s not sure he can take it anymore.
he hangs his head low, but he’s not frustrated or angry at you, it’s just the fatigue from a weeks worth of filming all done in a days work was catching up to him quicker than he thought.
he trudges up the stairs silently once again, only speaking when he finally makes it to your shared bedroom. you notice him at the edge of your bed when you shift and wail out for the millionth time today.
jaemin instantly notices the tears coming down your red cheeks, and all his sleepiness goes away as his senses are heightened, his body plagued with worry. “what’s wrong baby?” he asks, sprinting to the side of the bed your on and getting on his knees to face you.
you just look him in the eyes before whining again in response, changing into a fetal position with your arms glued in between your legs. you take some more time before answering, watching him watch you rock yourself back and forth before slowing down and opening your mouth to speak.
“i got my period,” you whimper out. “my cramps are killing me and these pills wont work!” you complained—gesturing to the bottle of midol that lay on your bedside dresser, almost empty.
jaemin only sighs in relief at the fact that its nothing life threatening making you this upset. he leans in to kiss your forehead and caresses your cheek with a small smile tugging at his lips. “why didnt you tell me this morning baby?” he coos.
being on your period meant one of two things: either you were gonna get frustrated and angry at every little thing that inconveniences you for the next week, or, you would barely be able to get up due to how bad your cramps got, laying in a bed a whining baby until your pills finally kicked in.
he usually prefers the first option. disagreeing and arguing with you is one of his favorite things to do, loving how sexy you are when youre mad. but, when this version of you comes out, he secretly enjoys it just a tiny bit more, the thought of being able to pamper and take care of you giving him a heavy sense of responsibility—and also because you’re his absolute everything, and he’ll continue to pamper you as you both grow old.
“it didnt come on until a few hours ago.” you pout, increasing the intensity of rocking back and forth slowly.
he raised his eyebrows in disbelief before looking raising his body to look at the sheets under you, grabbing the back of your leg as he does. “baby.. did you-“
“im wearing a tampon, i didnt bleed into the bed,” you answer quickly, causing him to sit back down and let out a huff of relief. “so you’ve been laying like this for a few hours? you didnt get up at all?” he questions.
“it hurt so much to move,” you start, the pout returning back onto your face as you continue. “i just dont know why my medicine has betrayed me like this!”
at that, jaemin leans closer and peppers light kisses all around your face. “it’s okay baby,” he breathes out calmly between a few kisses. “should i buy another brand?”
“yes, please.”
“okay, hang tight pretty.” he softly coos. in times like this, jaemin knows words of affection can greatly increase your mood, and so every few sentences he’ll add what he knows will help you calm down and be just a little more pliant with him. he stands up after kissing your forehead and tells you he’ll be right back—which is true considering the nearest CVS is a 2 minute walk.
on the way there, jaemin is just a tad bit worried on why the medicine isnt working for you, it’s helped you any other time and is actually the brand that helps the most. he laughs to himself after making a joke in his head that period cramps are like bacteria, the midol being used so much it got immune to it and came back stronger.
he earns the stare of a random dude next to him, who quickly scurries down the aisle to another before jaemin can even realize what just happened. he skins the products for period relief, grabbing the usual ones like tylenol, ibuprofen, even grabbing an extra midol bottle in case it does kick in and you dont have to worry about coming back.
as the bag swings in his hand, he takes out his phone to let you know he’s on the way back—not like you could see the text anyways, your phone probably somewhere in the room from being thrashed around due to your pain.
he pulls up safari on his phone and searches ‘medicine not working period cramps’ into the search bar to see if any other remedies might help.
he gets the usual alternative, a heating pad, which he actually means to order, giving himself a mental note to do that later, he scrolls farther down the first page until he sees a link from reddit titled ‘i fucked my gfs cramps away lol’
you hear the door open up again, whimpering loudly to let your boyfriend know the midol still hadn’t kicked in and that you were in terrible pain, still in the same position he left you. “i know baby,” he comforts, leaning back down at your side of the bed again to kiss you. he begins listing off everything he got from the store, saying you could try these other alternatives over the next few days, and hopefully they would work.
except they didn’t. nothing worked.
after the first 3 days, jaemin knows what to expect when he opens the front door after another long day at work to hear you wailing once again. he’s glad that he has the next week off, something about a scheduling issue with his company, and it’ll be fixed by the end of that week. he scurries up the steps, ready to see you in a fetal position—to which you are.
“hows my baby doing?” he asks, coming over on your side again and pressing his lips on yours. you give a small smile, looking back at him as you begin to explain. “the medicine didnt work, so im really not doing okay.” you shift your position, blushing just the tiniest bit from his question.
he looks at the bag on the dresser next to him, grabbing it expecting to suggest a new bottle, until he actually looks inside to see there’s nothing in the bag, and you had already tried every kind over the course of these 3 days. he sighs before staring at you.
his brain goes back to the first day you got your period and he was walking home from CVS. the reddit link about some dude fucking his girlfriends cramps away. “babe, i have an idea.” he suddenly blurts. he tells you to stay put (not like you could go anywhere anyways) as he rushes to grab his phone from downstairs.
he comes back up looking slightly shy and suspicious, and you can’t help but raise your eyebrow in question as he leans down to your side of the bed and opens up his phone. “on the first day of your period,” he starts, continuously making eye contact between you and his phone. “i saw a subreddit about a guy who fucked (he makes air quotes around the word fucked) his girlfriends cramps away.”
you stare at him for a second too long before remembering you have eyelids, and instead blink at him. “…what?” you finally squeak out.
“i- i know it sounds crazy but— just look” jaemin turns the phone around so you can see it clearly.

i fucked my gfs cramps away lol
it actually works. me n my gf were chillin n her period randomly came on 3 days earlier than expected. it was too late to go to the store n buy medicine n her cramps instantly started hurting. at that moment, she said she only wanted me.. which i thought was weird, but a real warrior gets blood on his sword, so we had sex n it basically soothed her cramps away. she even fell asleep right after we finished. lol W.
“jaem, we need to take a look at your search history together someday.” you chuckled, so confused on how he even came across this.
“wha— did you even read the post?” he tries to reel you back in to what he thinks is important, and it is NOT his search history.
“yes?” you reply. “i dont know, i’ve never really heard of this type of stuff. and that’s the only thing pertaining to what, like— period sex?”
“are you seriously calling it period sex?”
“thats what it is!” you huff, sitting up a bit on the bed with newfound strength from frustration.
“okay— but if we tried?” jaemin asks, staring at you with his eyebrow raised.
“you sure its just not you wanting to have sex?” you quip, laughing harder when jaemin stares back, completely unamused by your shitty joke.
“you seem an awful lot better now.” he points out, seeing as you were barely able to smile just a few minutes ago. “ever seen a strong woman before? my cramps are still killing me yes, but you’re making it better. thank you baby.” you respond, reaching your hand out to caress his cheek.
he smiles before asking, “how about we do one more day with the extra midol i bought you, and if it doesn’t work, then we’ll do.. period sex..”
you tap your index finger on your chin, looking up at the ceiling pondering for a second. weighing the pros and the cons doesn’t seem like a hard challenge, the pros being good sex and potential cramp relief, and the cons being maybe a blood stained bed? thats 2-1, so you shrug your shoulders before telling jaemin he has a deal.
midday the very next day, it hits you the hardest its ever hit. youre laughing watching tiktoks on your phone, trying to ignore the pain because of course, the new bottle of midol didnt work—but suddenly its like the wind alone gets knocked out of you. you drop your phone and instantly start to cry, tears streaming down your face before you have the chance to process it, which catches the attention of your boyfriend.
he was editing photos of you both together just in the other room, thankfully he had turned his music down low enough—which he did initially to listen to you laugh, smiling to himself in secret before he heard something drop and your cries.
he got up so quick he forgot to pause his music or even save the picture he was editing to his drafts. the pc abruptly being turned off that made the music lag a second longer after it he pressed the power button, and his picture he was editing lost all its progress, something jaemin would have to make up for later, but his only worry was you.
when he runs in there and you make eye contact its like you both know what’s about to happen now, so jaemin takes the initiative. he climbs onto the bed and peppers kisses all over your face to try and calm you down, wiping your tears and kissing under your eyes. “its gonna be okay, baby.” he coos, wrapping his arm around your waist as he climbs over you.
once hovering over you with his legs in between yours, he stares at you for a moment with an unreadable look in his eyes. but whatever it is, it doesnt make you feel scared at all, and its almost as if you melt into the bedsheet under his glossy stare, as if he had released pheromones and they were giving you bliss.
he goes to kiss the side of your neck, traveling down in little bites and a few sucks here and there before he reaches your collarbone. “my pretty girl.” he praises you. you hum in response and can’t tell if the heat you feel is from your period or arousal. he puts his hands on your waist, rubbing comforting circles as he continues to kiss all over your face and neck.
you whine from the stimulation and cramps combined, and jaemin starts to tug at the hem of your shirt. “wanna take this off for me?” he questions, and you nod quickly as you begin to sit up and pull it off of you. jaemin groans when you do, tugging the strap of your bra up and letting it snap back down. you moan at the sting, trying to squeeze your legs together but failing due to him being in between you.
he notices your needy attempt, and smirks. “are you excited?” he leans in, his lip just barely grazing yours, and hums in satisfaction when you whine out a needy yes. “mm. so ready and ive barley touched you.” jaemin teases.
jaemin reaches behind your back to skillfully unhook your bra and slides the bra straps down, whispering “fuck,” that almost comes out as a moan when he sees your breasts spill out of it. he takes one hand to play with one nipple as he sucks on the other, nipping and increasing in speed as you continuously moan. “you’re so fucking perfect for me.” he breathes
he slips one hand down to tug at your shorts, your cotton matching pjs you bought with him that are well faded from how much youve worn them. he finally takes his mouth off your breast to look down at your shorts, licking his lips as he looks back up at you. “jaemin..” you whine, frustrated with the cramps and the amount of time he’s taking.
“i know baby. my pretty girl cant wait any longer, hm?” he plays with the waist of your shorts, another wicked smile growing on his face as he tugs them down. now only in your panties, he goes back to devouring the rest of your body with his mouth and puts his knee directly to your heat.
you gasp out, finally feeling some type of friction after he’s riled you up. he chuckles at that, and his breath on your skin only gets you more hot and bothered, so you moan again. he bites your shoulder one last time before leaning back to focus all his attention on your bleeding heat.
“i think i see a little blood, did you leak some baby?” he taunts upon looking at your panties. youre too embarrassed to answer so you just whine out, silently pleading for him to do something to you already.
he giggles again, “its okay, you can’t help it.” he assures before he pulls your panties down and off, tossing them into the laundry basket behind him. he can see the string of your tampon sticking out, barely white anymore. he tugs along the string pulling it little by little before he stops, then repeats the action again.
the cramps start back again, harder, and tears instantly fall from your cheek as you bite back your whines, focusing as hard as you can on the little friction jaemin is giving you.
“shh,” he coaxed, kissing and licking your tears as they run down your face. “youre doing so well for me.” he praises once again, eliciting a moan from you.
“bet this tampon can barely fill you up,” jaemin mutters, tugging at the line again before he swiftly pulls it out completely. “bet i can fill you up better, dont you want that?” he stares at you, waiting for a response, smirking when you moan out a tiny ‘yes’, followed by a few pleas.
“good girl.” and thats when you finally notice his bulge, his length straining against his sweatpants like it hurts. he quickly pulls his pants and underwear down off completely, groaning when his length slaps against his stomach. you swore you were drooling. his tip leaking precum and slightly red from what you assume is his negligence.
he sees you staring and cackles. he spits onto it before calmly saying “be patient baby, im gonna give it to you.”
jaemin rubs the spit up and down his cock and lines it up with your slit, rubbing it back and forth a good few times—getting a smedium coating of blood on it. he looks up at you. “ready?” he asks. and when you nod with a small “please, jaemin.” he pushes his tip inside.
he nearly passes out from the sensation.
if being inside you pre-period felt like going above the stars, he was in an entirely different galaxy right now. your generally warm, but youre warmer than usual, and the sticky feel from the blood only makes it better. he’s so lost in the sauce he forgets he has to keep pushing. he groans as he slides in deeper, hearing you whine fuels his arousal even higher.
“you’re taking me so well, even on your period. such a good girl for me.” he praises through a few more groans. once he’s fully inside, he gives you (and himself) a minute to adjust. for both of you, its a foreign feeling but its something he definitely wouldnt mind doing again—especially if it mean itd help you.
“jae..” you can only get a little out before the cramps come back once again, squeezing around jaemin from the pain. “does it hurt?” he asks, leaning in to kiss you on your cheek. when you nod, he licks a stripe from your cheek to your jawline. “dont worry, it wont hurt anymore.” he assures, and thrusts.
you gasp, instantly grabbing the sheets as jaemin picks up a pretty good rhythm, tears fall from your eyes as you feel overwhelmed, but you smile at jaemin when he locks one hand with yours. “does it feel good baby?” he groans out. “feels so good,” you whine, feeling the pleasure times 10.
he picks up speed, eliciting another moan from you almost immediately, him leaning down every once in a while to lick some part of your body he hasn’t marked yet or suck your tits. “you feel so good, pretty.” he breathes.
you hum in response, too busy drowning in your own pleasure and pain as he thrusts like this is his first time having sex. little by little, you notice your cramps disappear until they’re fully gone, now being able to enjoy your boyfriends cock in full ecstasy.
jaemin sucks at your neck, making you squeeze him, and he swears under his breath, slowing down a bit but picking back up his rhythm. “don’t do that baby, im sensitive.” he warns you. you only squeak in response.
he speeds up his pace again and you whimper loudly, begging jaemin not to stop. “told you,” he mewls. “told you i can fill you up better than that tampon.” you nod your head rapidly, indeed feeling full from the girth of his dick inside you, pulsating, throbbing, and thrusting.
a few more thrusts and you start to feel it, the knot in your stomach balling up tighter and tighter with each shift of your body. jaemin notices too, the way you suddenly start to get more stiff, squeezing the life out of him, and tightening the hold you have on his hand. “g-gonna—“ you try to let your boyfriend know.
you were teetering on the edge of your orgasm, and when jaemin whispers in your ear how he loves you, the knot finally unravels as you climax, twitching and moaning his name loudly as you let go, him helping you ride it out as you slowly calm down. it’s hard to keep a steady rhythm with your walls fluttering uncontrollably around him, but once he’s sure you’re done and good, he resumes. “good job baby, now it’s my turn.” your boyfriend declares, speeding his thrusts up.
he reached his climax quickly after a few more thrusts, cumming inside as his hold on your hand tightened up, you squeezing to milk him for every last drop. “sh-shit,” he howls one last time before looking down where your bodies connect to see the mixture of gummy white and red sticky liquid mixing together.
jaemin collapses ontop of you as he catches his breath, nothing except him breathing in and out frantically. he kisses your neck and tells you how great you did when he notices you passed out.
he smirks to himself as he pulls out carefully to not get any blood on the bed. when he does, there’s a sticky pop sound that jaemin’s not sure if he likes or dislikes. he grabs a towel to clean you out and change you into some more panties and a shirt of his first before cleaning himself off and changing himself as well.
when tucked into bed, he kisses you on your forehead, slips his hand underneath the back of his your shirt and gently caresses your back. he feels dizzy, still coming down from his high little by little, but it quickly goes away when he sees how beautiful you look in the moonlight, your soft features giving you a sleeping face of that of a doll. he swears you’re the most gorgeous thing on earth.
“goodnight baby.” he whispers, smiling when you unconsciously shift facing him at his words.
he rocks you a little back and forth, slowly lulling himself to sleep as he whispers more praises into your ear until his shifting finally stops, and he’s knocked out.
now he knows what to do when medicine doesnt work next time.
