Izuku having to be muzzled during sex because he bites so much. The biting isn’t even a conscious action, but Izuku’s teeth are /sharp/ and neither Katsuki nor Eijirou

would like to have huge bite marks scarring their shoulders, thanks.

God, just the idea of Izuku’s mouth chomping aimlessly around nothing in the cage of the muzzle as Kirishima fucks into him as Katsuki clenched around his cock. He’s in the middle of his two handsome boyfriends

as his ass is being stretched by Ei’s fat, hung cock while his own cock is being fucked into Kacchan’s ass without him doing much. Eijirou holds the leash for the collar connecting to the muzzle in his hand as Izuku gurgles and chokes on bitten growls and moans of pleasure.

His mouth drools and froths with saliva as his eyes shimmer with tears of unsaturated pleasure. His toes cramp from where they are curled tightly as his thighs shake. The rubber of the muzzle bites into his skin in a pleasant, almost grounding feeling as he loses himself in lust.

His cock throbs deep inside of Kacchan as the blond grinds down on it, sweeping quivering fingers through his hair. Eijirou whispers filthy nothings into his ear, hitting his prostate with each rough thrust that makes his asscheeks clap against the man’s thighs.

Each thrust and grind has his body feeling like its been shocked, lashes fluttering and he gurgles wanton moans and half-bitten growls of pleasure. He tries to bow his head forward to press against Kacchan’s shoulder - to /bite/ - but even with the muzzle, its a fruitless

attempt as Eijirou tugs the leash and pins his head against the warm pillow and his cheek, grumbling filth against his freckled skin. Izuku peeks at his handsome red-haired boyfriend who looks dashingly and dangerously handsome with his hair down and his teeth glinting in the

afternoon sun peeking through their closed blinds. As pro heroes, none of them are exactly keen on having photos taken through their windows while they have sex.

“Fuck,” Eijirou hissed as he tightens when he runs those sharp teeth over his neck. Izuku gurgles a groan of arousal

at the bitten curse tumbling from Eijirou’s mouth. He wasn’t one to swear even after living with he and Kacchan, who both have awful habits of swearing. Izuku’s been around Kacchan his entire life, it would be odd if he hadn’t picked up on his swearing.

Kacchan grinds down

on his cock, nipping at his cheeks as he groans and huffs against his cheek, lapping at the tears that drizzle down his face. His thighs quake at the feeling, the bunched muscles tightening under his skin. His hands find Kacchan’s hips, molding to his hip dips perfectly.

Izuku is in another world of pleasure, gripping at Katsuki’s hips and ass as his eyes roll back, staring to shake and clamp down as he cums, the leash pulled on harshly, cutting his air supply as Ei’s thrusts speed up, chasing his own climax.

Kacchan had cum after him, his throbbing cock being fucked in and out of the blond’s ass with each jostling thrust Ei did. The blond’s pretty cock painted his clenched abs white as the two moan. The pleasure is almost painful for Izuku who snaps and gurgles whimpered groans,

teeth aching to bite /something/ to ward off the pleasure as Ei finally cums in him, fucking him full of his cum.

After the three ride their orgasms out, Izuku’s muzzle and collar is removed and his jaw is massaged as he lays in a puddle of boneless goo.

His mind has long since melted after being assaulted with pleasure from both sides, bathed in kisses and warm towels before they tucked in for the night.

end. the image of Izuku being muzzled and sandwiched between katsuki and eijirou makes my little brain implode on itself. it’s FBEHZHGAGSAG. best way to describe it i think
