You decided to order a period pain simulator after seeing trends online of men giving them a try and suffering. As being the only AFAB individual in a house full of testosterone it only makes sense to see if it too works on demon men- after all, a man is a man regardless of species, right? Surely seven demons could withstand a mere period pain simulator…. Right….?
Lucifer
He knows about periods, yes, Lilith herself did go through them- however, as far as he was aware, they were not as excruciating. She just was a moody muffin who became overly blunt and would be extremely hungry. Yes, she did want to throw hands at times but he shrugged it off for the most part.
Yes female angels have periods too, he has been witness to some rather brutal ones where the female angels just get insanely emotional or start wanting heads to roll. Demon females too, he’s seen plenty at the local grocery store go bonkers over snacks and the hygiene products.
He had no idea exactly how painful these could get, oh boy would he find out.
Was hesitant at first, after all, you seem to be in agony during your monthly visitor but he decides to give this a go just to see how you truly feel. He’s seen plenty of females, angel, human or demon, go through them and each have their own unique emotional range and pains.
What can possibly go wrong? It’s just a silly human device that is made to simulate period pain. How could this ever hurt the great Lucifer himself?
How bad can it REALLY be? Sir, prepare to feel some agony.
“Is this even on? Hmph, this is easier than I thought.”
Sir, that is because it’s only at setting 1, be ready for worse.
Immediately eats his words the second you crank it up to about three, he refuses to admit it hurts and simply says he’s a demon, this is nothing.
Crank it up to about five and he is already sweating, he still refuses to throw in the towel and admit defeat. He must hold out for as long as possible.
“Y/N… you really feel this?! Every month?!”
“Yes, but imagine more pain and blood gushing out of your southern hemisphere- oh and tender breasts, followed by a fever, bloating, nausea, and insane cravings.”
“Remind me to curse Father out more for this- ahem- design flaw…”
You crank it up to seven and he caves. He is done. He has unshed tears in his eyes and is on the bed writhing in agony.
“Honey, want to try levels nine and ten? That’s how it usually feels for me on the first two days.”
He literally looks you in the eyes and says he will never do that again, however… he just discovered an interesting punishment device in this thing.
I feel bad for the sorry chap who has to suffer the simulator by the hands of Lucifer himself.
After experiencing the period pain simulation he will go even more above and beyond for you during your period.
He runs to the store faster than Mammon when he hears the word “money” to buy you snacks, pads, and anything really.
“You know, level 10 is the equivalent to early labor pains.”
Oh absolutely not, nope, and he thought level 6 was labor pain.
You are hereby exempt from taking classes in-person while on your period. You will become an online student those days and you will be required to relax and take it easy.
If his grudge for his Father wasn’t already big enough that grudge just skyrocketed so high it’s practically a missile to the Celestial Realm.
Mammon
He’s mildly familiar with periods, despite having a little sister he’s still an idiot as to how biology works in that sense.
He has an F (32.60%) in biology currently
He understands the b*tchy attitude and the craving part but the blood part…? Not really. Tell him about bleeding for a week straight and watch this man dial 666 (Devildom’s 911) for immediate assistance in getting his human to the hospital because of Father above you are obviously dy*ng and you need help.
The minute you tell him about this simulator and how it’s supposedly painful and can simulate a period he gets curious and thinks this is a great way to show he’s manly enough for you.
Mammon, you will suffer worse than any of the punishment Lucifer has put you through.
“Can’t hurt worse than any kick to the balls! Ha! This is simple! I’m the GREAT Mammon, I got this!”
Mammon, sweetie, a kick to the balls is nothing to this. It’s scientifically proven that period pains are equally as painful as a heart attack.
He whimpers as the simulator is strapped on
“Y-yo what gives?! It hurts!”
“Mammon, it’s not even on…”
You turn the dial onto the lowest setting, one, so far Mammon is holding strong, nothing too serious.
“Just feels like I gotta fart- like, not a big one but a good sized one.”
Turn it up to about three and he is already clutching his gut and whimpering.
“O-ok! N-now I feel like I gotta sh*t! But there ain’t any sh*t to sh*t! Y/N THE HELL IS THIS?!”
You crank it up to about six and he gives up. He is on the ground crying like a baby.
He swears that Lucifer gives less painful punishments than THIS.
“TURN IT OFF!! YO Y/N TURN IT OFF!! THIS IS WORSE THAN ANYTHIN’!! GETTIN’ KICKED IN THE NUTS IS NOTHIN’ TO THIS!!”
He will also swear that getting “the cut” was less painful than this simulator and will wholeheartedly d*e on that hill.
“This is like… my third lightest day in terms of flow, so yeah- this is painful but just uncomfortable.”
“TF YOU MEAN JUST UNCOMFORTABLE?!”
Man is ready to throw hands with your uterus and demand it stops hurting you.
Mammon feels even worse knowing he picked on his little sister when she was on her period and vows to never anger a lady on her monthly ever again.
“I-is it true ya don’t get this when yer pregnant…? If so, uh….”
Leviathan
He’s heard of periods of course, mainly from anime and manga. He knew of them a bit back when Lilith was around but never really thought much of it.
He is legit scared of them though because Lilith would bite and would get extremely moody on hers and he only ever was aware of the emotional aspect of periods.
Little girl chased him into his room and became very chihuahua like when on her monthly.
He thought the blood part was something only in anime and manga but…. Shh, Y/N, let him figure that out himself.
He’s familiar with the trend, he spends his time scrolling through FabSnap for trends or other things.
“LMAO what normie stuff! Putting themselves through pain from some measly human machine ROTFL!”
“Levi, that measly human machine hurts worse than getting kicked in the balls and is as painful as a literal heart attack.”
“Y/N, PLZ, that’s gotta be some normie rumor and they’re acting in front of the camera- that thing is so small that it totally can’t do something like THAT! LOOOOOOOLLL!! So yeah, my balls are fine, I’m fine, and I’m NOT gonna look like a normie whining on the floor!”
He lifts his shirt and puts the stickers on where they belong he sits in his beanbag chair and waits for whatever you have to throw at him.
How bad can this normie thing be?
He feels a small ounce of discomfort when it’s at one, just brushes it off and is slightly unfazed.
“Just feels like I ate something weird- lmao like that really awful Ruri-Chan collab I went to in-”
To shut him up you crank it to three.
“Ooofff! W-why does it feel like I really gotta sh*t? Is that all a period is? Feeling like you gotta run to the bathroom all the time?!”
Oh Levi, if only you REALLY knew….
You crank the simulator up to six and he screams like a baby, his scream is so high pitched it may have almost broke Henry’s fish tank….
You crank up one more level and oh goodness is he screaming even louder.
“TURN IT OFF!! TURN THE DAMN THING OFF OMG!! THIS HURTS!! OMG THIS HURTS!!!”
“That’s like- my second or third heaviest day, give or take. Sometimes it feels worse. That’s still doable but hurts.”
He will legit look at you with the face of ‘what the absolute f*ck’ while crying.
Like Mammon, will wholeheartedly d*e on the hill of “the cut” hurting less than this simulator- hell, that was wimp level compared to a period pain! Level uno!
Totally the tutorial for the game called pain.
Leviathan will want to throw hands with your uterus and will feel immense guilt realizing how he didn’t do enough for Lilith when she was still around.
“I-if anime has taught me anything t-then I um… t-then I’m gonna treat you m-much better, y/n…! W-wanna watch some anime now…?”
Please give him hugs after that simulator! He needs that desperately!
Satan
Oh he knows, he’s very well aware of how periods are painful, sometimes even more painful depending on the person.
Satan has heard of the simulator and is aware it’s supposed to be excruciating for men, however, that will probably not have any effect on him- he’s a demon. Demon males are stronger than human males-
What? Lucifer was in agony?! Lucifer caved from a mere period pain simulator?! Mammon and Levi too?! Challenge accepted.
You’ve never seen this man rip his shirt off so fast and strap on the simulator in your life. He was eager to prove he is stronger than that stupid Lucifer.
Level one? Really? Is that thing even on? This is NOTHING!
“This is easy, nothing, if this is what a period truly feels like then it’s not too unbearable. Perhaps the books were wrong.”
He eats those words immediately when you crank the simulator up to four.
“O-okay, this is uncomfortable. I feel like I seriously have to run to the men’s room… there’s nothing to release yet it feels like I have food poisoning… hhhnnnggg!!!”
You crank it up to six and he is in tears and gritting his teeth. Agony is setting in and he is digging his nails into his pillow.
“MOTHER F——”
A lot of swearing, not just modern swears, oh no, he will let out swears from the first ever civilizations and ancient peoples. If there was ever a swear word dictionary you best believe this man would have written it.
“SON OF A MOTHER [insert any swears you so wish here]”
Ok, please get one of those TV censored buttons in here. The bleep button will be going nonstop at this point…
“HOW THE [censored] CAN YOU [censored] EVEN [censored] TAKE THIS?!”
If you could tally every swear this man has said you may have filled an entire notepad by now and then some…
Please see your nearest Purgatory Hall for an angel’s blessing to your ears once this has concluded, thank you!
At seven he is still trying his absolute hardest not to break, he absolutely has to beat Lucifer, he needs to be better than him! He refuses to fail!
Please insert any swears from the 14th century here please and thank you! :3
You crank it up to eight and that is it, he is immediately caving, he yells in absolute agony into his pillow. He is sweaty and in tears.
“W-what the absolute f*ck was that?! That… the books never said it would hurt that terribly! How are you even alive, Y/N?! If it’s truly as painful as a heart attack you seriously need to take the week off!”
“Hm? A week off? Well, about that, we usually just suffer silently as we go about our days. Chocolate is a game changer truly.”
His jaw drops, he cannot begin to comprehend how the hell you are even able to walk after going through such a painful experience. Let alone how it even feels to have a full crimson waterfall for 24 hours seven days a week or less depending on the person.
“Oh and I’m also moody, nauseous, bloated, crave weird things and purposely read sad books or watch crime shows. In the mornings for some people it can mimic that of morning sickness and really make it unbearable. Fevers included.”
Watch this man begin to go through all his books to find ways to curse your uterus into never harming you again.
“Y/N…? Did I beat Lucifer? What level did he cave at?!”
You tell him he caved at seven and this man’s ego has skyrocketed. He is the most cocky man in the Devildom.
Congratulations, Y/N, you just literally made this man so full of himself he will probably not go back to normal for at least another 666 years at the least….
Asmodeus
Oh hon, he KNOWS about periods, he knows all the dirty details that come with it and literally everything about them. It’s kinda his thing.
Oh you didn’t know he tracks your cycle too? Oh hon, PLEASE, this man knows what’s up! Did you honestly think he did not know how to track these things? He helped his own little sister track hers and understand how to track them.
He’s heard of this trend going around and he can’t help but feel bad for every AFAB person who suffers period pains for real and without a simulation machine.
“Hon, you want me to try this out? Alright then~ a little pain can be fun you know~” *insert little winks and smirk*
Asmo, no, not THAT kind of pain…. *sigh*
Please don’t bonk him, he will make that hornkee jail worthy too…
He gets into some cute and comfy shorts from Victoria’s Secret and takes off his shirt. He makes sure to get on his bed so he feels at least some comfort.
Asmo is actually legitimately scared, he knows they are painful, he has seen you in agony and understands that there is undoubtedly pain in the package, he just does not know how much pain.
Can it be worse than the pain of getting his jewels busted? Definitely. Is it as painful as a heart attack? Science says yes.
He straps the stickers to his lower abdomen and braces for what happens next, he gets even more prepared by putting a pink fluffy headband on to pull his hair back in case he starts sweating… eew! Hon, no, sweat is totes gross and he cannot sweat and ruin his hair!
You turn it on and he winces, it’s not too painful, just uncomfortable. He understands this will only get worse and oh Diavolo is he bracing for impact.
“Y/N, hon, would you be a dear and hold my hand~?”
You comply hold his hand, he’s already squeezing it a little but not too tightly.
You crank it up to three and he is already wincing more and doing breathing exercises like he is a woman in labor. Admittedly, it is rather entertaining to witness…
“Oh goodness, hon, this… HHHNNNGGGGG…!!!! Oh this is certainly getting uncomfortable…”
You crank the device up to about five and he squeezes your hand tightly and lets out some swears. Sweat drips from his brow and he legit looks like he is a woman giving birth.
“Y/N, OH MY GOSH- OH F—! HHHHNNNGGGGG!!!! IT HURTS SO MUCH AND NOT THE FUN KINDA PAIN!!”
“You can do this, Asmo! You made it to level five and that’s incredible!”
“SHUSH!! OH DIAVOLO IT FEELS LIKE ITS AT TEN! AAAHHHH!!”
However….. RIP your hand and your ears as this man screams. A LOT.
The device goes to seven and he squeezes your hand even harder, honestly, you’re surprised it’s not broken.
“I FEEL LIKE I HAVE TO PUSH!! OH DIAVOLO THIS IS- AAAAAAAAAAAAHHHHHHH!!!!”
Push what? Nothing. Sir, you have nothing to push. You are definitely holding back your laughter as this is almost as good as the top Hollywood acting you see in films. Get this demon an award!
Breathing exercises continue and he continues to unintentionally look like he is having serious contractions and about to pop out a child- he’s not but… the simulator is doing a number on him for sure.
Don’t worry, he won’t spawn a random demon like a certain brother of his. Won’t mention any names… but… Lucifer…
You turn the device to about eight and that is it… he is done for.
His poor face is a mess with tears, some snot, and all red… give him a hug, a blanket, some chocolate, some skincare products, and a ton of kisses!!
“H-hon… how in the realms do you survive that agony?! How does anyone survive that?! Are we sure you didn’t strap a labor simulator on me?! Because if you hurt that much you are staying right here with me and I will make sure you feel incredible during your monthly visitor~”
“I feel all that along with the bloating, crimson waterfall of doom, the bizarre cravings, the mood swings, and the need to- ahem… fill in the blank…”
Say no more. This man is READY to go! Hon, you need only say the word and he is all set and ready to pounce!
“Before we do all that, hon, perhaps we can have a quick cuddle session~? I could use that after what you did to me~ and since you had your turn being in control…. Fufu~ you’ll be on the receiving end when we have our fun, love~”
Hello? 666 (Devildom’s 911)? Yes, I’d like to call an ambulance for Y/N when Asmo has finished his… yeah… Y/N may need a wheelchair…
Beelzebub
Oh? Periods? Like in Writing Class…..? No, Beel, sweetie… like the week of blood and agony.
He knows about them a little bit, he understands that there’s a super painful time for AFAB people but never knew it meant blood.
Beel remembers Lilith being very moody and hungry when she was on hers, he remembered how mad she would get if anyone touched her sweets.
He may have almost suffered a broken nose because she was really upset he ate her chocolate cupcakes and now understands that you need sugar to feel better.
Is it medicine…? Sort of, Beel, sort of like medicine, sweetie.
You have to hold his hand and explain the whole process and why it happens, he does get a bit confused but now understands why you smelled like iron those times- he just thought you are a big juicy steak and got all the juices on you somewhere.
“So you bleed for a week or a few days…? And you don’t… you know…. Go…?”
“Yes, for a a few days to a week, no biggie, it’s all part of the process. See? I’m alive, don’t look so scared, Beeley Bear!”
Give him some head pats and make sure he knows you won’t be d*ing anytime soon because of a period.
After promising to take him to a buffet for lunch he agrees to try the simulator, it truly did not take much convincing as he truly wanted to understand and also…. Food.
Beel will take off his shirt and get comfortable in a pair of workout shorts before putting the pads on his lower abdomen.
He is actually very nervous, while he can take pain and all he does actually get scared.
You switch it on to level one and he is confused, wheres the pain?
“Is this even on, Y/N…? Did I break it…? I’m sorry…”
“No you didn’t break it, Beel, this is just level one of ten.”
You crank it up to three and he is starting to feel something. Not much, but something.
“Feels like… hmm… feels like I may need to run to the little demons’ room but not too bad. Is this normal…?”
You nod and crank it up to about five and he has a hand over his belly wincing a little, he truly feels like he needs to run to he little demons’ room but knows there is nothing there.
“So all this is just the feeling of seriously needing to run to the little demons’ room…? So far so good I guess… just feels very uncomfortable. Like a tummy ache…”
“Yeah, it feels like that at times, I get it, but there is obviously more to it than feeling like you need to make a mad dash to the nearest available ‘little demons’ room’ as you put it.”
Crank it up to eight and he is legit starting to feel the pain.
“Y-Y/N… Y/N this r-really hurts now…. feels like when I ate a can of expired tomatoes from 400AD….”
Y/N, you made Beel start to cry, I truly hope you feel terrible now… he has tears in his eyes and is whimpering like a puppy.
You immediately turn it off because quite frankly seeing Beel upset was what truly did it for you.
“I’m sorry for eating your snacks during that time of the month, Y/N, for now on, you can have my custard and as many of my snacks as you want. Oh, and if you wanna go to a restaurant for lunch or something let me know! You’ll get anything!”
Beel is literally the sweetest guy ever, he will literally make sure that you get everything and more during that time of the month because you deserve it.
Belphegor
He knows a bit, not much but definitely enough, he understands that hormones play a huge part and make you an emotional mess, he also understands that there’s blood involved and that there’s weird cravings but the rest? Fill in the blanks.
He remembers Lilith being extra clingy with him when she was on her period, yes she would threaten to bite if he so much as moved the wrong way when she would hop into his bed at night.
One time Belphie made the stupid mistake of saying Lilith looked like she was ran over by a stampede one morning when she had a rude awakening with the crimson flow of doom and got slapped for it.
Like Lilith, you seem to have inherited the same attitude along with a plethora of others… lovely.
“So that’s why you’re always extra b*tchy- hormones and pain, huh? I get it, I’d be just as b*tchy if I were in your shoes- oh I can be in your shoes…?”
Belphie is a bit confused at first at what you mean, he first thought you meant a trip to Solomon to make a potion that would give him the sensation of a period but apparently not.
Oh thank goodness, gives him an excuse not to get out of bed and to remain in his pyjamas and cuddle you and his favourite pillow.
“So is it supposed to hurt or anything? If so this is weak as f—k.”
“Belphie, it’s not even on.”
“Oh… then turn it on before I consider forfeiting and taking a nap, nap time is about now- O-oh…”
Turning it on shuts him up immediately and he sits there a bit confused.
He looks mildly uncomfortable, still a bit confused as to why it’s not that bad- after all, you make it sound as if your insides are literally becoming outsides.
“That’s it? Y/N, not gonna lie, this is boring. I thought this was supposed to be painful.”
Turn the dial up to about four and he’s wincing a bit.
“O-oh sh*t… Y-Y/N I really feel like I need to run to the little demons’ room…! Hhnngg….!”
“It feels like that, doesn’t it? That feeling lasts about two to three days for me depending on flow and length of period.”
He just glares at you as you turn it up to six, he is clutching his pillow and swears just as much as Satan… he also breaks out the 14th century swears along with the first ever swear words of early civilizations.
“SON OF A [censored]! THIS [censored] [censored] HURTS LIKE A [censored]!!
That’s cute, Y/N, you thought Satan was the swear word machine. No, it’s Belphie. This boy can swear! And this little sh*t can get away with it too because he’s the youngest…
“Want to cave in, sweetie?”
“F—K NO! I WANNA BEAT LUCIFER…!”
Turn the dial up to seven and he’s starts crying loudly, this honestly hurts too much for him and it is not pleasant in the slightest.
“TURN IT OFF DAMNIT!! TURN IT OFF…!!”
He has sweat pouring from his brow and tears streaming down his face and looks like a hot mess, you immediately take the stickers off his belly and give him a huge hug.
“Y-you go through that…? Every month or so…?”
“Yes, but of course there’s blood, mood swings, cravings, waking up nauseous sometimes with a small fever, and even being bloated. Sore breasts too on occasion.”
“How the absolute f—k are you even allowed to leave the house and go about life with all that?! No, you are gonna stay with me and cuddle. No way you should have to go through that.”
Belphie will literally buy you any and all products you need from Akuzon while you cuddle because there is no way you should be made to move- well unless you need a new pad or tampon or something or to go…. But food? He will ask his twin to be the delivery guy with snacks and drinks.
“What the f—k was Father thinking when he made this? I mean- I know why it happens and all but what the f—k was his overall logic?!”
Like Lucifer, has plans of giving Father the what for with this “design flaw”.
“New prank idea- make a potion to use on Lucifer that makes him feel this pain for a week straight!”
Belphie…. No….
Belphie yes 😈
