This is my little modern au! advent calendar series where each demon I write for gets their own connected one-shot. I also will be writing for Muzan, Kokushibo, Douma, Akaza, Sekido, Karaku, Urogi, Zohakuten, Urami, and Kaigaku as well. Enjoy!

“You're back.” You approached him with a mug of hot chocolate as he removed his shoes at the front. “You kind of ditched me last night. I had to tell Zohakuten's hooker which room to go to. So thanks for that.”
Aizetsu sniffed the scent of chocolate wafting in the air. “I would've preferred coffee or tea…” His frown only grew, forced tears welling in his eyes. “It was a long night.”
“I can add whipped cream on top.” You shrugged, attempting to placate him as you approached the hotel fridge to grab the whipped topping you had bought earlier.
“You know I'm lactose intolerant.” He crossed his arms over his chest as he began following you. He didn't act akin to a lost puppy, but rather your shadow. He despised leaving your side, high maintenance to a fault. “Do you want me to shit my pants?”
Maybe you'd deserve it, you thought to yourself bitterly.
Instead, you bit your tongue. “You didn't get much sleep, did you?”
He just stared at you, allowing you to stare at the dark circles beneath his sullen, blue eyes. His hair was a little disheveled as well, his lazy, messy bun long gone. All that remained was the navy blue hair tie on his wrist.
“Urogi's wife wouldn't stop crying for an epidural.” Aizetsu finally accepted the hot beverage from you. The warm ceramic cup felt pleasant to the touch. He had always found comfort in warmth, unable to find joy in winter weather. “Our mother gave birth naturally and so should she.” He stood there expectantly, waiting for you to finish garnishing his drink. Your lips twitched upwards as you added the whipped cream, returning to a melancholic disposition as it began to melt immediately. “That bird brain brother of mine almost gave into her weakness. He couldn't stand the screams.”
“And you?” You raised an eyebrow.
Aizetsu took a long sip, enjoying the way the warmth permeated throughout his throat. As he swallowed, his pity party continued, “It was difficult to sleep through.”
“Oh, my poor baby,” you clicked your tongue, “However will I make you feel better.” The aluminum can clinked against the counter as you sat it down.
A heavy sigh slipped past his lips, “Don't patronize me, woman. It makes me sad.”
The pad of your index finger ran across the top of a button, slipping it out, “Aizetsu…” Your voice shifted into a low, sultry pitch, dancing across his eardrums. “...you're a much simpler man than you're willing to admit.”
His mouth went a little dry, but he continued to shamelessly stare as you unbuttoned your shirt lower and lower. He felt himself gulp at nothing at the realization that you had foregone wearing a bra. Aizetsu would never admit it, but you knew exactly how to make him feel joy. His erection grew at the sight of your nipples hardening through your shirt.
“And you are far sluttier than you're willing to admit.” He couldn't help himself.
“And yet…” Fabric cascaded down to the floor as you bore yourself to him. “...you married me.”
Aizetsu was rendered speechless as you grabbed the canister again. You flicked your wrist twice, shaking its contents and added a dollop on one of your nipples. A chill ran down your spine at the feeling of the cool, smooth texture being applied to your body.
In an instant, he latched on to suckle the sweet treat from your breast, nearly knocking you over in the process. His hot tongue slobbered around your areola, fully enamored by your chest in a way that only rivaled Karaku's tastes — not that Aizetsu would ever admit to sharing any commonalities with that pervert.
Aizetsu’s love for tits went way beyond sexual desire. He was deeply infatuated with the warmth a woman's bosom could provide. They were one of the finer things in life; he understood that very well when one day one of his father's mistresses suddenly had implants. Or when he would listen to his mother's heartbeat as a boy. There was just a calming factor that he couldn't live without.
“So soft,” he whimpered, nuzzling his face into the soft tissue. His hand fondled your neglected breast, squeezing it firmly in his grasp. His cock was rock hard, straining in his pants while drowning his underwear in sticky sap, tip weeping with each painful throb, “So warm.”
So easy.
You sprayed more whipped topping, this time on the back of his hand. His knees wobbled as he gazed at you with woeful, half lidded eyes, tongue dipping into the sweet cream as he lapped it away like a kitten. While he was utter trash, he was very aware of his good looks. They were a weapon in their own right.
Your fingers curled around his wrist, dragging him towards the couch. “Now tell me, did they have a boy or a girl?”
Aizetsu shuffled his socked feet against the hardwood, frowning at the thought of Urogi. He didn't want to think about his dimwitted twin while you had your tits out, and he didn't want to think about Urogi's baby.
Glumly, he humored you, “They had a boy. The thing looked just like grandpa. Grotesque.”
“I'm sure the kid isn't tha-” He shut you up with a picture Urogi had sent to their work group chat. Sure enough, the baby boy was pruned and discolored in the forehead.
Unable to help yourself, you scrolled through Aizetsu’s messages. After all, there was a woman in the chat.
Kokushibo: Your baby is overweight.
Douma: So so so cute 🥰❤️
Urogi: Yeah
Urogi: He's my lil chonk
Urogi: Loves mama's tits almost as much as I do
Nakime: What an odd thing to say.
Karaku: Nahhhhhh
Karaku: That's so real
Douma: Perhaps my fiancé will give me a baby soon 🤔
Sekido: It goes marriage THEN children.
Urogi: LMFAO the kid just pissed on his mama
Akaza: Cute kid.
Douma: GUYS SHE SAID YES!!!
Douma: 🥳🥳🥳
Sekido: No one cares.
Zohakuten: Congratulations!
Sekido: ???
Kaigaku: That baby is ugly as hell
Urogi: 😑
Urogi: I will pound your ass
Karaku: Can I watch
Kaigaku: ?
Douma: Kinky 😋🤭
Urogi: Huh
Aizetsu’s phone buzzed in your hand twice.
Urogi: My wife has informed me not to say that
Urogi: I take it back because I respect women 😋😇
Your pupils met with the ceiling. Prior to marrying his wife, Urogi once said that he only wanted to wife her up to have someone to cook meals for him. He was so full of shit it was almost laughable.
Aizetsu sat on the couch, impatiently taking his cock out to languidly stroke it as you read through his messages. His thumb danced across the over sensitive tip and he swallowed a whimper as you finished up. He was used to your constant snooping, but it displeased him nonetheless despite being equally toxic and doing the same.
“I had a long night.” Rehearsed tears brimmed his melancholic eyes, drenching his dark eyelashes with every blink. He cupped your cheek as a hot tear slid down his face until it evaporated from the blood burning beneath his cheek. “I need a woman's touch.”
“So needy,” you chided, lowering yourself to your knees between his own. You couldn't understand for the life of you how a man could be aroused after watching a woman crown that same day. Granted, it wasn't that big of a shock given how Aizetsu and Urogi were nine months younger than their older brothers on the dot.
Bile rose in your throat at the realization of the nature in which Aizetsu was conceived. He was none the wiser, simply staring at your tits like a prize he had bought, almost dehumanizingly so. You swallowed the acid burning your esophagus — along with your pride — shaking the can once more and painting his cock and hand in sweet cream.
The corner of his lips twitched, ready to complain about the cold, or whipped cream inevitably ending up in his foreskin. But before he could lash out, he was enveloped in softness. You had granted him his own personal bliss, pushing your breasts together around his cock to bounce the soft tissue in your hands. The sticky, sweet substance was smeared on your skin, melting into your pores with your shared body heat.
You leaned forward, kitten licking away the lingering remnants of saccharine cream. The tip of your tongue swirling around the engorged, leaky head. A mixture of pungent salt and sugar hit your tastebuds, lips wrapping around him so sweetly. You gently caressed his aching gland with each gentle brush of skin to skin contact.
The muscles in his thick thighs tensed, nearly trembling beneath his slacks from the night before. He gripped the edge of the couch cushion for dear life, overly sensitive to the motions of your tongue and breasts. He tossed his head back, holding in a moan as his lips were forced into a straight line. Toxic masculinity forced him to contain the almost feminine whines his vocal chords desired to create.
You felt so warm; your breasts enveloped him like a soft blanket, shielding him from the frozen oasis outside, allowing him to shake the chill in his bones that hadn't left since his three A.M. smoke break. After watching Urogi's wife pump colostrum, he needed something to distract him. Aizetsu would never admit it, but he truly had next level mommy issues.
If you didn't know better, you'd assume that Aizetsu would be satisfied with a simple tit job for Christmas. But men like Aizetsu were never satisfied.
Even when he shamefully whimpered, unable to swallow the sound, he wasn't satisfied. Nor was he when he iced your chin and bosom in white icing. So you swiped up some of his seed with the pads of your fingers, allowing the moisture to collect on your fingerprint.
His pupils were blown wide, chest rising and falling at a faster rate than usual. But his voice was no longer lost. “That was great, b-”
You shoved your cum covered fingers in his mouth, forcing him to taste his own cream. He squirmed beneath you, only arousing you further as heat pooled between your legs. The confusion and subtle anger in his pretty, blue eyes was positively adorable. His messy, long hair only further added to his allure, unintentionally seducing you.
“Why would you do that?” His voice was even more soft spoken than usual, intentionally so.
You shushed him, pressing your saliva soaked fingers to his plump lips. “Shh, maybe if you don't complain for once, mommy will sit on your face for Christmas.”
He cringed at the term, but never went silent so fast.
Imagine pressing your tits together and rubbing them along Aizetsu’s cock as he whimpers. Biting his lip to repress the saccharine noises emanating in his throat. Shamelessly watching as the soft tissue glided along his shaft. Practically melting as you lean forward to kitten lick away the bead of precum glistening along his slit.
He wasn't going to heaven, but he was getting pretty damn close.
Stepbrother!Aizetsu, who initially looked at you with bored indifference when you first moved into the family home. He hadn't asked for a sister, but there was no point in complaining either. He was stuck with you and might as well make the most of it.
Stepbrother!Aizetsu, who had already grown weary listening to you complain about your loser boyfriend after only a couple of weeks. It was obvious to him that your boyfriend didn't deserve you. He'd sigh, and mumble under his breath enviously about how nice guys always finish last.
Stepbrother!Aizetsu, who had snuck into your room late at night to block that douchebag on everything. Ripping off the bandaid forgot you while you were none the wiser.
Stepbrother!Aizetsu, who comforted you when that prick “ghosted you”. Taking advantage of your vulnerable state, rubbing your back as you cried while feeding you lies. Hugging you for the first time, and not from the side either. Holding you tightly, basking in the way your tits felt against his chest. Eventually offering for you to spend the night in his bed, but not like that. Or so he claimed. You always woke up to morning wood against your ass after that.
Stepbrother!Aizetsu, who was protective, not possessive. Scaring off any man that so much as looked at you. Going to far as to torment his own brothers. He knew how men thought after all, he was only looking out for you.
Planting seeds of doubt into Sekido's mind. Convincing him that you were a worthless whore. Giving him zero reason to engage in so much as small talk with you. Manipulating Sekido into despising you with venomous lies.
Sending your nudes to Karaku and deleting all of the evidence from your phone. Falsely allowing Karaku to think you were fair game; allowing Karaku to creep you out.
Although, Karaku took it way too far. Sneaking into your room to grope you one night. While Aizetsu wanted to chop his brother's hand off, it did open up an opportunity to convince you to keep sleeping in his bed. Because at the very least, Aizetsu kept you safe. Intentionally assaulting someone was much different than waking up with an erection.
He'd gaslight you whenever you cried on his shoulder about the situation. Telling you that you must've sent the nudes by accident, and forgotten about it. Shaming you like a child by mentioning how you shouldn't even have such lewd photos of yourself in the first place.
Pretending like he didn't picture them every night when he…
Aizetsu trained Urogi like an animal. Negatively reinforcing him whenever you were in his presence. Slipping laxatives or offering him ice cream whenever you were near. Tricking him into subconsciously associating you with a stomach ache.
He didn't even have to do anything about Zohakuten. The future serial killer was too busy on Reddit to even bother leaving his room.
After that you were successfully isolated. Leaving you with only your dear stepbrother in your corner. Convincing you that nobody would ever love you quote like he could. At the very least, he stuck around. Everyone had left you, you were the common denominator, not him. You were lucky he still wanted anything to do with you.
Aizetsu was truly convinced he knew what was best for you. That only HE could take care of you properly. That only HE could Love you properly.
Stepbrother!Aizetsu, who faked an entire toxic relationship for an excuse to cry to you. Knowing you'd understand after your ex. Using his faux girlfriend being cruel as an excuse to cradle his face in your bosom.
Fighting off a smirk from creeping up his face, completely in love with your naivety. As well as with the way your breasts felt against his face. Leaving him yearning for a titjob.
Stepbrother!Aizetsu, who knew just how to help his cute, little sister out when he heard unsatisfied moans through your bedroom wall. Finally snapping; desperately needing to fuck your pretty pussy.
“Are you sure about this?” You were having second thoughts about this. He was your stepbrother after all.
Under normal circumstances, you would've declined his taboo offer. But it had been so long since anyone else had even engaged in a conversation longer than five minutes with you. Let alone make love to you.
And it wasn't like Aizetsu was really your brother.
He found the way your nose crinkled with uncertainty adorable. Maneuvering one of your ankles over his shoulder, spreading your legs further apart. Pressing into your inner thigh with his palm.
Aizetsu rubbed the swollen, pink tip of his cock between your puffy folds. Gathering wetness and marking his territory with his precum. Claiming you as his property.
“How sad. Can't you trust me?” Sorrow poured out of Aizetsu’s mouth, drowning your senses in a calculated melancholy, “After everything we've been through?” After all of his hard work?
Something was off. You couldn't quite place it, but deep down some part of you had to have known.
“I do!” Your voice lowered in decibels, “I do… It's just…” Your teeth sunk into your bottom lip as you trailed off.
“But?” Aizetsu was rapidly losing patience with each passing moment. Pressing in just the tip into your neglected cunt, stretching it into the shape of his fat cock.
We shouldn't be doing this, you wanted to say. Instead only a shaky, shallow breath came out in its place. Tears pricked the inner corners of your eyes as his penetration pushed deeper, tearing you apart.
He was huge!
Bullying your poor, improperly preparing walls into conforming to his size. Molding into an imprint of his girth, forcing your pussy to memorize him. To welcome him.
Taking you gently — he wasn't a monster after all. Allowing you the privilege to acclimate to the stretch. You had been a good girl after all.
If you had rejected his advances, Aizetsu wouldn't have been so kind.
He would've purchased potent sleeping agents, slipping them into your drinks while you weren't looking. Perhaps he'd even tell Karaku that you wouldn't fight it this time.
Maybe even film it, leveraging it over your head. Allowing you the choice between sucking him off or shattering your reputation. He'd have no remorse in exposing you with a leaked video.
Well, maybe one remorse — allowing others to see that perfect body.
Luckily, Aizetsu hadn't had to go that far. You allowed him into his bed, hesitant or not, you wanted him too.
The moan you let out when the tip of his cock nestled deeper, caressing your cervix, told him everything. You knew who you belonged to, and from now on you'd take care of your big brother every night.
