Chapter Text
It was your third year at UA, a promising young hero filled with energy and waiting to finally become an official hero. Her teacher Eraserhead of class 3-A made sure to tell the class to be careful with whom to intern this year, it would make or break if they would be seen as worthy heroes when they enter the world.
You had originally planned to go with Edge shot again whom you had, had for the last two years but him being in the hospital from a villain attack sadly meant you had to choose someone new.
Eraserhead offered to let you intern under him, he made it clear that you were one of the few kids he tolerated and wouldn’t mind. But you wanted to do something new, why didn’t you choose Eraserhead?!
Instead while scrolling through your request your eye caught on something. Pro Hero Miruko had sent one! She had never accepted an internship before making it all the more exciting.
As you clicked on the email you got more and more excited as she explained how she wanted you to intern under her! The number four hero in all of Japan wanted you? She had always been your favorite hero, minus Eraserhead, but still, you couldn’t believe it.
Time practically blurred as the week before internships went on, packing and making sure all the right little pieces of info were in place and ready to go. Word had gotten around that Miruko was choosing an intern for the first time and pride filled your chest.
Finally, as you got off the train to the district she stayed your heart beat out of your chest with excitement. You had met up with one of her sidekicks who took you to her hero agency where you were led to your room.
You were disappointed that you wouldn’t be able to see her till tomorrow morning but you worked with what you were given. You had been scheduled for three days of training until another four days of actual patrolling.
It was perfect, you fell asleep with a smile ready for anything.
The training was exhausting you quickly discovered that just after two days every muscle in your body was burning. But you got to train with the Miruko so it was still a win.
She was just as cool as you imagined, smart, strong, and knew what she was doing, a fine hero. She always pushed you to your limits every session, wanting to make sure you were giving everything you had.
However, something was off about her… Now and then you would catch her just staring at you, like, if you were doing squats in the corner of her eye you would always see her staring.
You chalked it up to her just making sure you were doing everything correctly. She was treating you so well! Making sure you were getting fancy meals for breakfast lunch and dinner. She always insisted on eating dinner with you which was a little weird but again you chalked it up to her just making sure you were okay.
It was the final day of training before she started taking you out on patrols and she had decided to end early. You had collapsed on a bench drinking water while trying to catch your breath as she sat next to you.
“I must say, I’m very impressed with you so far. I made the right decision to take you.” She ruffled your hair shocking you as you turned to her. “You mean it?”
She flashed a large smile at you showing off her fangs, “Of course kid, you have what it takes to be a hero. A mighty fine one.” Her calm tone and relaxed body were a stark contrast to yours, exhausted and gleaming with sweat.
“T-thank you Miruko, I’m glad you asked me to be your intern.” You smiled at the rabid hero. “Don’t thank me- a good girl like yourself should know how perfect you are.”
You were at a last for words at her, you couldn’t help the blush rise to your face. Mirko must just be friendly, she was attractive sure but it was nothing more than a crush one might have on some celebrity actor.
She took the water bottle from your hands and set it down, your body was still frozen as she took your chin with one hand and tilted it up to her. “W-wait what are you doing?-“ You were cut off as Miruko pulled you in for a kiss.
For a second you were still in shock that you couldn’t even register what was happening until she shoved her tongue into your mouth. You immediately pulled back and got up, “What the- what the fuck?! Why-“
Mirko stood up and looked down at you, it became very apparent the height difference and how much bigger she was than you. She grabbed your chin again, “You can’t blame me, your just too cute~” she tried to go in for another kiss but you immediately pushed her away and started to back up.
“Get away from me, y-you weirdo!” You got ready to use your quirk in defense, a part of you knew you would never be able to beat her in a fight but you would want to try.
Before you could even think Miruko had easily pinned you to the wall In the large gym. Your back pressed against the cool glass mirror as your arms were restrained behind your back with cuffs.
“Get off me!” You tried to activate your quirk that let you breathe fire but nothing came. You realized with fear that she had used quirk canceling cuffs. “Don’t be that way bunny, but you are so cute when riled up.”
She slid one of her legs between yours, rubbing against your clothed clit. You jerked as she grabbed your chin and shoved her tongue into your mouth. You couldn’t do anything against her, Mirukos strength being over triple your own probably more.
Her hands slid up and started grabbing at your clothed boobs from under the sports bra you were wearing. Her leg was making quick work of turning you on and you hated how you quietly moaned into the hero’s mouth.
Eventually, she pulled away from the kiss giving you much need air, “Please, let me go I-I don’t want this.” Mirko only smiled at you, “You will eventually, I’ve wanted this ever since I saw you fighting at the sports festival. So pretty and adorable just for me, I just had to make you mine.”
Your struggle started again trying to get off the leg grinding into your now wet core, the wet spot became apparent on Mirukos leggings as you were brought closer and closer to the edge. “That’s it, good girl- come for your mommy.”
You squeezed against her thigh as you came shamefully into your underwear. “Now- let me go.” You panted as she thankfully removed her leg. “Oh but the funs only just began~”
Mirko effortlessly left your bridal style in your arms, she swallowed you into a kiss and started somewhere. Your predicament of being tied up and already exhausted made it hard to fight back but you still tried in a futile attempt.
Eventually, you were set down and able to stand on your own. You looked around the room and fear rose in your chest as you realized it was Miruko’s bedroom. She took off the cuffs on you and you wasted no time in trying to through a right hook at her.
She caught it with ease as she pushed you onto the bed. Your throat heat up, ready to burn her in an attempt to escape but didn’t hand a chance as she use her speed to quickly put a syringe in your arm.
Your eyes widened as your could no longer use your quirk. “What the fuck did you just put in me! You monster ill make sure to have Mr. Aizawa arrest you!” You screamed at her with your body restrained as she pinned you on the bed.
“Don’t worry it isn’t permanent, I’m not so cruel as to ruin your chances of being a hero, think of it as a way for me to calm you down without you burning my tongue.”
Her voice was sickly sweet as you tried to fight her as she bound your hands with cuffs to the bedpost. You resorted to your legs but it was no use. Tears came to your eyes as she started to take your shorts off.
“NO! Stop, please not this. Stop-“ You were crying now but Miruko didn’t care, she continued to cut your shirt and bra off leaving you in only your underwear. The cold air made your nipples hard and you shivered feeling so bare.
“So beautiful, your so perfect and all mine.” Mirko peppered kisses down your jaw down your body till her head fit perfectly between your thighs. The thin piece of cotton did nothing to hide your wet pussy, soaked through with your previous release.
You continued to sob as she peeled away the piece of fabric leaving your cunt completely exposed to her. “Don’t cry baby, I promise I’ll make you feel so good” That was the only warning you got as she dived into your cunt lapping up all your juices.
Her arms grabbed your thighs as you tried to squeeze her head but her arms were too strong and easily spread you open. Her tongue expertly licked across your folds, drinking up your juices like it was honey.
At first, you had been begging her to stop as you cried but you couldn’t deny just how good it felt and you eventually found yourself moaning softly as you tried to ignore her ministrations. She sucked harshly on her clit drawing a squawked moan out of you.
Mirko smirked against your cunt and continued to suck harder on the sensitive bud until you were cumming into her mouth which she gladly licked up. Overstimulation started to set in but she quickly removed her mouth after all of your come had been cleaned up.
“Fuck, your such a good girl you know that? Want to be a good girl for your mommy?” You snapped out of your haze of pleasure as you suddenly remembered what was happening. You struggled and pulled on the cuffs but it was futile and only succeed in making your wrists sore.
You felt two fingers str prodding at your cunt making a new wave of heat run through you, “Are you a virgin? Do you want mommy to be your first? And only?”
“Wait- stop please, if you let me go I won’t tell anyone I-I promise.” You hoped that maybe Miruko would see what she was doing and let you go but as her fingers started rubbing circles on your clit you knew she had no intention of stopping.
“I already know, a pretty little virgin that’s all mine. You have no idea how much I dreamt about having you, about kidnapping you from your dorm and fucking you like a good little pet.”
Miruko didn’t stop speaking she slowly sank her two fingers into your tight cunt, “But I had to be careful, I needed to make sure no one could stop me.” You moaned sinfully as Miruko scissors you open with her fingers.
You looked away as the hero stared at you, “Don’t be a shy little bunny and don’t forget to call my name” Her fingers roughly shoved into that spongy spot inside you making you moan Miruko in your mouth.
A third finger shoved into your sopping hole making the overstimulation all the more clear. “M-Miruko I can’t please,” “That’s not my name, call me mommy~”
Her voice was smooth and you tried to ignore the fingers fucking into you, not wanting to call the woman taking advantage of you mommy. You started moaning more to your displeasure, as you eventually found yourself squeezing Mirukos fingers with your cunt as you came.
She didn’t stop though, continuing to scissor you and make you cry. “Nononono I can’t Miruko, m-mommy~” You felt sick to your stomach but you could deny how good it felt. Miruko leaned down and pulled you into a kiss as her free hand massaged one of your boobs.
They were shamefully small in comparison to Mirukos, not even able to compare. It didn’t take long till you were brought to another orgasm. Your body slumped into the soft large bed, passing out felt like an option but Miruko removed her fingers from you.
“Your so good, such a good little bunny.” She whispered into your neck, sucking Hickes onto your skin and gently biting at the space between your neck and shoulders. “You’ve had your fun, now please just l-let me go.”
You hated how small and pathetic you sounded, you were so weak you couldn’t even escape from her. Tears burned in your eyes threatening to spill but you wanted to stay strong. “Aw~ you know I can’t do that baby, your so adorable that I don’t think I can ever let you go again.”
She got up and smirked at you, opening one of the drawers by the bed that was conveniently out of your sight. You heard it close and eventually Mirko was back between your thighs and gently trying to shove something into you.
Your body jerked and tried to pull away but Miruko only needed to press a hand to your stomach to easily hold you still. It felt like a small egg that was shoved deep inside your virgin hole. “Be a good girl while I go clean up, I want to be my best when I fuck you.”
You noticed a small remote in her hand and fear filled you once again as the small toy inside you started to vibrate. “No- don’t please, I cant mommy don’t-“ You couldn’t even form words as the vibrator pressed deeper into you.
“Don’t worry I’ll only be about 10 minutes.” She winked at you and left into the bathroom in the large room. You pulled on your restraints in a futile attempt as you came again around the toy inside you. But it didn’t stop-
You sobbed as you heard the sound of a shower being turned on as your orgasm was built back up.
