"izuku midoriya?" you hummed, voice cutting through the sterile air of the waiting room, along with the sound of flipping paper. the dingy blue lights buzzed faintly over the patients, casting a flow over the row of plastic chairs as well as the patients in a pale colour. some were cuddling with their masters, seeking some sort of warmth and comfort, while some were alone, eyes fixed onto the ceiling, or nothing at all.
exactly like the figure tucked into the chair in the far corner of the room; his knees were drawn up just slightly while his boots rested on the plastic of the chair, and his cheeks were a flush of pink on his pale skin. his fluffy tail lay limp against the chair, occasionally catching the tip twitching.
the sound of his name made the soft ears on top of his head twitch before swivelling towards you before the rest of his body could catch up. he rose up with a flinch, his stomach feeling heavy, tail curling behind him defensively.
your smile tugged at the corner of your lips, letting your gaze drift over him and taking in the way his fingers subtly trembled and the way his green-coloured ears twitched even more when you stepped closer.
“follow me,” you hummed, turning around without waiting - papers in your hand rustling as you moved through the hallway. behind you, you could hear the shuffling of his boots, almost like he was about to fall over with each step.
as soon as you stepped into your office, your body had relaxed, the smell of medicine and metal disappearing in an instant, replaced by some sort of jasmine and old books.
you gestured towards the small seating area by the window, the armchair worn-out and scratched with a old blanket that had definitely seen better days. “please, sit here and make yourself comfortable.”
he gulped a large glob of saliva that was stuck in his throat as he had slowly walked towards the chair, sinking in an instant of warmth and familiarity.
while he was getting comfortable with the environment, you had busied yourself with the electric kettle, the water hissing as you prepared tea, setting the plate of cookies on the desk between the two of you - steam curling in the air.
“here,” you said softly, nudging the cup towards him, “you don’t have to drink it, but it’s there if you would like.”
his fingers had twitched, hovering over the mug’s handle, before wrapping around it with carefullness, not drinking but allowing the hear seep into his palms.
you had settled into your chair across him, fingers gliding across the keyboard as you pulled up his file - the screen casting a white glow across your face as you scrolled through his history. his behavioural notes, last check-ups, medication. everything seemed normal to you, at least.
“so, izuku…” you hummed, eyes still scanning the data. “last time you were here, you had your monthly check-up. but that was a week ago, so…” you finally looked up at him, taking a small sip of the steaming tea. “what seems to be the problem?”
his face flushed as he shifted in his seat, the soft blanket and worn chair creaking under him. his tail, which had been draped over the armrest, now thumping against the soft cushion, ears perking up as a low whine escaped his throat before he could even stop it.
“w-well…” he started, voice coming out breathier and more strained than usual. he cleared his throat, trying again as his hands rested against his crotch - closer to where the strain of his pants sat, each word falling out clumsier and whiny. “master had told me there was something wrong with me and you could only help me.”
his eyes darted everywhere but your face, cheeks a flushed red, the smell of the tea making his breath heavy.
“said something about being too… hot? or - a heat.” his voice cracked on each word. “i-i don’t really remember. i just… i’ve been feeling really strange. and restless - it’s like my skin doesn’t feel or fit right - like i need everything off my body.”
you nodded to each word, watching his movement as he finally looked up at you, eyes glassy and vulnerable.
“hm, i see.” you smiled, typing something on your computer before pushing away from your desk. “see, don’t worry izuku, this is completely natural for you. as your master said, you’re in heat - this is where you need to mate, make babies.”
izuku sighed in relief at your words, a warm smile spreading across his lips. “that’s good… i was scared you wouldn’t be able to understand what i was talking about since master was not here.”
his eyes sparkled as he heard your soft laugh, letting out a small chuckle to himself as well. “you can fix it right, doc? what sorta medicine would i need?”
a soft smirk appeared on your lips, one not so innocent. your finger tapped innocently on your chin, as you sat back with a screech. “well, you can’t get better with medicine persay…”
izuku’s face dropped at each word, panic filling his face. “w-what do you mean– i can’t get better? there’s no medicine–”
“it’s a different sort of treatment, a special kind.”
in an instant, his face relaxed and returned to one filled with excitement. “oh, that's what you meant, i was worried you meant i had to deal with this for the rest of my life!”
you rose slowly, moving towards the bed tucked in the far wall, one reserved for patients who need to lay down during examinations, or even when you need rest.
you perched on the edge, mattress dipping slightly under your weight, palms smoothing across the fabric of your thigh.
“come here,” you hummed, voice gentle. your eyes lowered, half-lidded, more of a silent invitation than a command. “sit.”
his head tilted, the green eats perched on top of his head, turned with curiosity. but, his brows furrowed, worry creeping onto his neck.
“i– i don’t really know…” he dodged, thumbs running over one another. “master doesn’t like when i sit on anyone’s laps – or even their lap. they say its… improper? or i’ll get too attached.” his voice grew uncertain. “are you sure it’ll be okay…?
you nodded slowly and reassuringly, smoothing out the nonexistent wrinkles on your pants.
“positive,” you said, voice carrying a promise. “i wouldn’t offer if i wasn’t sure. and… i wont tell your master if you won’t.” you held a finger to your lips in a hushing motion.
a smile tugged at the corner of his lips. “
“well… okay, if you say so!”
he let out a soft whimper as he stood up, each step was clumsy while his tail wagged in short sweeps behind him. as he walked closer, you couldn’t help but notice the unmistakable tent in his pants, straining against the fabric.
he perched on your thigh carefully, weight settling against you like he was a feather. his head hid into the curve of your shoulder, nuzzling into the crook of your neck as if he’d done it multiple times.
a soft sigh escaped him as your arms wrapped around his torso, pulling him closer. “you’re… warm,” he murmured, his voice muffled and drowsy against your skin.
you laughed at his observation, the sound vibrating through your chest and onto him. your fingers began to move, tracing slow circles around his waist, feeling the tension in his muscles unwind under your touch.
“izuku,” you said gently, making him hum softly. “can i pet you?”
the word, ‘pet’, hit him softly, his eyes flying open widely, his head nodding with enthusiasm that his fluffy green hair tickled your neck and cheeks.
“yes– please!” his voice cracked with desperate excitement, tail wagging so hard now it thumped against your leg rapidly. “master doesn’t pet me enough, oh please, doctor! i’ve been so good, i promise, i’ll be so still, won’t move at all–”
“shh,” you soothed, laughter softly escaping your lips. “i believe you; you’re doing so well already.”
izuku let out a soft whine as your hands threaded through the fluffy mess of his hair, palms brushing against the base of those velvety green ears, the fold of his ears perking every so often, thumb tracing the edge of his ears.
a sound escaped his lips, something between a groan and bark rumbling against his chest. his whole body melted against yours as he didn’t have any bones, his head lolling further into the crook of your neck, eyes fluttering closed and hips slowly rutting back and forth.
“you’re so soft,” you murmured, more to yourself than him, fingers continuing their gentle strokes. “such a good boy.
a shiver ran through his spine at your words; you could feel his nails dig lightly into your dress shirt, breath coming in slow and heavy puffs against your collarbone, the tent in his pants practically growning by each second.
“thank you–” he whispered, one quiet and thick you almost missed it, “thank you so much, doctor.”
you kissed the top of his head softly, one of your hands sliding down his torso, resting just above his abdomen. “what about this bulge in your pants?”
his cheeks flushed at your words, soft moans escaping his lips as he tries to explain. “well, master say’s don’t– worry about it… that i should wait in my room until it goes away,” he whines, his palm moving to your wrist. “but it just hurts, especially when its pushing against my pants like this.”
his eyes were glassy and pleading; you could practically feel the pulse radiating from it.
you nodded slowly at his words, expression softening with sympathy. you pressed another small kiss against his head, letting your lips brush his hair as you spoke.
“well, i can help with that.” your voice was soothing. “can you take it out for me, izuku?”
he lifts his head in embarrassment, eyes widening in shock, lips parted, then closed, then parted again.
“take it out-?” he swallowed a hard lump in his throat. “uhm… are you really sure thats okay?” he rambles. “master said to never take it out in front of guests, and especially when it’s all leaky and hard like this. they said it’s– indecent? and– i should be ashamed, and–”
“don’t worry,” you cut him off softly, voice firm. your fingers withdraw and give him space, letting him know it was up to him if he’d like to continue or not. “it’s okay if you’re not ready; we can stop.”
“n-no, i do–!”
the words burst out of him desperately; he grabbed your hand with both of his, pressing your palm firmly against the straining bulge in his pants, his breath hitching and a shudder running through his body.
“if doctor knows how to fix it…” he whispered, voice hopeful, “then please, i trust you.”
with shaky hands, he fumbled with the waistband of his sweats, movement clumsy with urgency, pushing them down with his boxers, fabric pooling around his thigh. his cock sprang free, one clearly thick and heavy, slapping against his belly with a wet sound in the cool air of the office.
a loud, whiny moan escaped his lips as his head fell back against your shoulder with a relief that washed over him.
you couldn’t help but stare, your breath getting caught in your throat. he was… massive to say the least. the length was bigger than anything you’ve seen before; it flushed deep, the green hairs that trickled up his torso, and tip already dripping with precum that fell down his length.
your hand reached out, fingertip barely brushing his shaft, gathering the moisture that sat and pooled. he whimpered loudly at the contact, hips bucking involuntarily, chasing your touch.
“so pretty,” you muttered to yourself, eyes tracing each vein, the way his cock curved. “so responsive as well; you’ve been holding this in for a while, haven't you, izuku?”
he nodded restlessly, tears pricking at the corner of his eyes. “yes–yes, doctor– mommy. ihave. it hurts so so much, please!” he cried, hips bucking with each stroke. his mind fogging up at the pleasure.
“wanna– ilove this so much, mommy.” he gasped, his hands frantically unbuttoning your shirt just so your shoulder is revealed, teeth biting harshly into your skin. “fuckk…”
“wanna get you filled with my puppies,” he mumbles, your hand moving faster, the other playing with his ears softly, whispering words of filth into them.
“you wanna cum, wanna breed me?” you taunted, fingers pressing against his tip, each dribble of precum leaking faster and faster.
“yes–yes–! please, mommy-!” he whined, his teeth sinking into your skin, deep enough to draw blood, to leave a scar that would last eternity. “wanna fill you up so bad.”
you coo’d at his response, hand speeding up as you pulled his hair, earning a sharp moan from his lips, eyes filled with tears and cheeks pinker than ever.
“iwanna–cum– something… it's coming out– ♡” he moaned, string of cum quickly shooting upwards, covering both your stomach and his own; however, your hand never faltered. “w–wait, i made a mess, sl–slow down!”
you let out a sinister laugh as you felt his body get rigid, your hand never slowing until his second orgasm, one stronger and louder than the first one. his thighs twitched, lips unlatched from your bruised shoulder to moan loudly.
the cum sprayed more wetter, thinner than before, leaving damp trails against the whites of your shirt.
your finger slowed down against him, but never stopped, just enough to keep the pleasure, but not fast enough for an orgasm. “how was that, izuku?” you hummed, kissing his tear-stained cheek.
without thinking, he had grabbed your wrists and flipped you both over, back hitting the rather uncomfortable mattress.
“i think… mommy needs a punishment for not listening to me.” he laughed, slowly pulling down your own trousers, revealing those pretty lace panties, damp in the centre.
his teeth grazed your inner thigh, biting sharply, earning a loud gasp from you. “let’s see how you like it… hm?”
