The school bully and the "new" kid

A/N: I know it sounds cliché, but I did want to write here so I just went with the idea I've had for a while. Alert! Very horny Muzan and horny Michikatsu!

Michikatsu smiled, he was back at Kimetsu academy. He had to leave because his father had a project in another city. He smiled as he thought on how to surprise his boyfriend, Muzan. He looked around until he saw a crowd, surrounding someone with long white hair and pale skin. 'Muzan?'

Michikatsu walked towards the crowd and gasped,not out of horror, but admiration. Muzan wore a skirt with heels, he stood above a kid, which Michikatsu ignored. Michikatsu pushed through the crowd and wrapped his arms around Muzan's waist. "Guess who's back?" he smiled, nuzzling his face in Muzan's neck.

Muzan hummed, luckily for the kid on the ground, Michikatsu stopped Muzan from potentially landing him into the hospital. He gave him a glare before the 'Leave,' face. He then put his hands on Michikatsu's. "Mmm... Let me guess, my boyfriend who returned?" he smirked.

He chuckled softly as he pulled away slightly, looking up at Muzan with those beautiful eyes of his. His smile grew wider when he saw how happy it made Muzan look. "Yeah," he said quietly, leaning forward again to press their foreheads together once more. "I'm here now."

Muzan smiles. "I missed you, you know?" he pouted even though they did call quite a lot of time. They'd call after school, do their homework together and just call almost everyday. "I missed you too," he said quietly, bringing his lips to brush against Muzan's lightly. "And I had to come home to see you, of course." He grinned, his hands still resting on Muzan's hips.

Muzan giggled, the crowd was slowly walking away, it was still 10 minutes before class, so they could spend some time together. Michikatsu took one last glance over at the classroom door before turning back towards Muzan. He wrapped an arm around Muzan's shoulders and leaned closer, pressing their bodies together tightly. "Let's go somewhere private..." he whispered huskily, giving Muzan another quick kiss before pulling away again.

"Michi, we're in school," Muzan poked Michikatsu on his forehead and deadpanning. "Someone could see us, you know?" the long haired albino huffed as he puts his hands on his hips. "No worries," he said quickly, taking Muzan by the hand and leading them down the hallways until they reached the empty stairwells. Once there, he turned to Muzan and pressed his body against his, kissing him deeply. "There's no one else here but us."

Muzan giggled. "Dear, are you that horny? And for what, mh? Is it because I'm wearing a skirt?" the albino raised an eyebrow at his boyfriend. He smiled widely, squeezing Muzan's ass gently. "Yes, and yes. You're adorable, you know that?" he said softly, running his fingers through Muzan's hair. "But you also smell good today." He chuckled and kissed Muzan again, this time harder than before.

Muzan hummed and kissed back before pulling away. "It's new perfume, ojii-san bought it for me," Muzan refered to Kagaya, his uncle and the headmaster of the school. "Oh really? What is it called?" He asked curiously, looking into Muzan's eyes.

"Clive Christian No.1 if I remember correctly," he smiled at his boyfriend while leaning against the wall, crossing his hands over his chest. "Well, either way, you look amazing~" he grinned slyly, wrapping his arms around Muzan's waist and pulling him close.

"Aww, thank you~" he smirked, as if he knew something that Michikatsu doesn't. "Mhm... I bet you've got a secret kink too, don't you?" he winked teasingly, rubbing his nose against Muzan's.

Muzan raised an eyebrow as he put his hands on Michikatsu's shoulders. "Mh? How'd you get that idea?" he asked curiously. "Just a feeling I had, my dear~" he replied coyly, nuzzling his face into Muzan's neck. "Tell me about your kinks, sweetheart."

Muzan laughed softly. "Not in school, dear. The bell will ring in just a minute." he stated, and just after he said that, the bell did ring. "Ah! Well then..." he chuckled lightly, letting go of Muzan and walking towards his class. "I'll see you after class okay?" he asked, smiling innocently. Muzan nodded and kissed Michikatsu's cheek "Love you!" he said before going to his class too.

"I love you too!" he shouted back happily, waving goodbye. Muzan smiled as he walked towards his class. He sat down on his seat and smiled when Michikatsu walked in. "Oh my, you're also in my class? How nice!" Muzan grinned as he lay his head on Michikatsu's shoulder, the teacher hasn't arrived, anyway.

"Hey there~" he greeted with a smile, putting his hand on Muzan's thigh gently. Muzan giggled and put his own head on Michikatsu's hand. "Love you," he said again before kissing Michikatsu's cheek.

"I love you too~" he grinned widely, running his fingers through Muzan's hair. Muzan smiled, until the teacher arrived. "That's ms. Kibishi. She's a bitch, not gonna lie," the red eyed man whispered in the taller's ear.

"She is?" he asked, raising an eyebrow. "Why do you say so?" Muzan sighed and rubbed his head. "You'll see," and just after, the teacher started to shout at the class, not the normal type, she acted like a psychopath.

"A-ah...well, what should we be doing now?" he asked nervously, looking around for any other way out of this situation. "Don't take it to heart, just wait until she stops shouting, which could be the whole lesson," he chuckled and leaned his head on his hand, which was on the desk.

"U-um, Muzan?" he asked hopefully, glancing over at him. "Yeah?" Muzan askedw turning his head towards Michikatsu. "Could you help me with someth-" the teacher interrupted his words, making him sweat drop.

"Shhh, if we stay quiet enough she'll scream until the bell rings, then we don't have to work," Muzan whispered. He nods, biting his lip. "Okay..." he whispers quietly, trying to keep himself calm while the teacher screams in anger at them all, even though they were only talking about something stupid. The bell rang and everyone went their separate ways, except for Michikatsu who stayed behind with Muzan.

The day went on as any other, until it was break. Muzan smiled at Michikatsu and led him somewhere. "You wanted to have sex, no? Well you're in luck," he flirted. "Break is 1 hour and 10 minutes long, so we'll be having fun for a while," he chuckled.

"Oho!" he blushed, smiling brightly. "So that means I get to play with your body?" he teased, licking his lips. Muzan giggled and nodded. "Mhm~" he purred, pushing Michikatsu in an empty classroom and locking it. "It's quite handy to be the headmaster's nephew, isn't it?" he smiled while twirling the keys.

"Hmhm! Yes, yes it is," he agreed, feeling excited already. His face flushed bright pink from how much he liked the idea of being in control. "And what are my duties exactly?" he asked, crossing his arms under his chest.

"Duties?" he raised an eyebrow as he walked towards Michikatsu. "Uh hm," he nods his head. "What would you like me to do, Muzan?" he asks slyly, wagging his eyebrows at him. Muzan giggled. "Fuck me against the desk, hard and fast," he said boldly, licking his lips.

His smile grew wider at the command. "As you wish," he chuckled, walking towards the desk. He took off his shirt and shoes, leaving only his pants. He positioned Muzan at the desk, spreading his legs apart and hovering over him.

Muzan shuddered in anticipation as a soft moan left his lips. "Mmm..." he moaned as Michikatsu traced his hand over his thighs. He grinned widely when he heard the moan. It made him feel good knowing he could make someone this happy just by doing what he wanted. His fingers moved up and down slowly, tracing small circles around Muzan's crotch.

Muzan melwed softly, spreading his legs wider. "Please..." he begged, shaking. He smirked before kissing Muzan passionately. Their tongues danced together, exploring each others mouths with want. When they finally broke apart, Michikatsu looked deep into Muzan's eyes. "Beg again." he demanded, pressing himself closer to Muzan. "I want to hear those words again."

The shorter whined. "Please fuck me..." he begged again as he gripped the desk as Michikatsu bend him over the polished wood. "As you wish," he chuckled. He put his finger in Muzan's mouth. "Suck," he commanded.

Muzan nodded, sucking on his finger. His tongue swirled around Michikatsu's finger, his saliva sticking to his finger. He groaned happily as he felt Muzan suckle on his finger. "Good boy," he praised, rubbing his thumb across Muzan's cheek. "Now beg for more." he ordered sternly, pushing two fingers inside of Muzan. "Tell me what you need, little one."

Muzan's body shivered at the pet namesw a whimper leaving his throat. "Please fuck me..." he panted, sweat forming on his face. He smiled widely at the request. "As you wish," he laughed. With that, he pulled out his fingers and stood behind Muzan. He grabbed hold of his waist and pressed him further onto the desk. "Spread your legs," he commanded.

Muzan nodded and spreads his legs further, showing his pink hole, it looked stretched. He smirked and ran his hands over Muzan's ass cheeks. "Have you stretched yourself beforehand? How cute of you, little one," he smiled whilst gently groping his thighs.

"Y-yeah... I-I didn't want to waste time on preparation," he admitted, blushing. He chuckled and kissed the back of his neck. "You're so thoughtful," he said, nibbling on his skin, "But it seems like you could use some more stretching before I enter you."

He pouted. "No... I want your cock, now," he whimpered, wiggling his ass. "Please..." He smacked his ass hard, making him yelp. "Patience, little one. Patience," he teased. "Or do you want me to take my time?" he asked, biting down on his shoulder.

Muzan moaned at the slam and bite. "P-please! I wanna have your cock in me..." he begged with a whine. He couldn't help but laugh at his adorable pleadings. "As you wish," he chuckled, slicking his cock with a bottle of lube he'd taken with him. He pressed the tip against Muzan's entrance, applying pressure gently. "Are you ready for this, little one?"

Muzan blushed and nodded rapidly. He gasped when Michikatsu pushed his cock in and grabbed his breasts. "Hngh!~" He grinned mischievously. "Such a good boy," he whispered into his ear, kissing his neck. His hips began moving slowly, thrusting himself deeper inside of Muzan. "Mmmh.. You feel amazing around my dick, little one," he cooed. "So tight..."

Muzan's back arched against Michikatsu's chest. He gripped the edge of the desk and moaned. The taller groaned as well, gripping onto Muzan tightly. "Fuck... So fucking tight..." he growled lowly. "Just keep moaning baby..." he ordered, beginning to pick up speed. "Your body is mine now, understand? Your body belongs to me. All mine."

Muzan nodded. "Yes yes! I'm yours! My body's yours! Only yours!" he whimpered as Michikatsu fucked him against the desk. He smirked, loving the way Muzan was so willingly giving himself up to him. He grabbed onto his hips, steadying him as he began to pick up his pace. His cock pounded into Muzan's tight ass with each thrust, feeling so good that he nearly couldn't control himself.

Muzan was gasping for air as tears fell down his cheeks from the fast pace. His cock rubbed against the wood as he was being fucked without mercy, not that he minded it. He kissed his forehead tenderly. "Good boy," he praised softly. "Keep going like that... Keep letting yourself go..." he murmured, continuing to pound away at Muzan's hole. "Letting yourself be used by me..." he added, grabbing onto his hair roughly.

Muzan's eyes rolled back as Michikatsu fucked him. "C-close!~" he warned as his cock kept rubbing against the wooden desk.

He smirked, tightening his grip on Muzan's hair. "Not yet," he breathed into his ear. "Not yet... Keep going, good boy..." Muzan panted as his back arched again, his cock twitching rapidly as he came with a cry of pleasure.

He grinned mischievously. "Now then..." he whispered, pulling out slowly. "What do we have here?" he asked teasingly, reaching between them to stroke Muzan's sensitive member gently. "Looks like someone likes having their holes filled by big cocks don't they?" he teased playfully.

Muzan gasped as Michikatsu stroked his cock. "W-wait! T-too much~!" he screamed, cumming again from his oversensitivity. He chuckled and pulled his hand away, looking down at Muzan with a smirk. "Too bad..." he said mockingly. "Looks like your little dick needs some attention too..." he teased as he pushed his fingers into Muzan's ass, stretching him wide open.

Muzan gasped. "Ah!~ Please Michi! 'S too m-much!" he sniffled, gripping Michikatsu's sleeves. He laughed loudly, pushing two fingers inside of Muzan's anus. "Oh really? Is that how badly you want my fingers in there?" he taunted, pumping his digits deeper inside of him. "Well then, let's see if I can make you scream even louder."

Muzan groaned. "AH!~" he screamed before covering his mouth, tears falling down his cheeks. He watched Muzan with interest, loving the way his ass was stretched around his fingers. "How much more can you take, my good boy?" he asked, pushing another finger in.

"I-I can't take... take it a-anymore!" he whined, almost falling if it weren't for Michikatsu. He slammed himself against Muzan roughly, making sure that every inch of his thick meat went home. "Mmmh.. So tight..." he moaned deeply, thrusting hard enough to make both men bounce off each other. "So fucking hot..." he muttered under his breath, sweat dripping off his forehead. "Because, dear... Remember our promise?" he smirked against Muzan's neck.

Muzan whimpered, his mind too foggy to remember anything other than these current events. "W-what...?" Michikatsu smirked. "Everyday means everyday."
