pro hero!kirishima x nanny!reader
𑣲 cw: smut at the end
Ejirou Kirishima was wearing thin. Managing his hero career, coordinating with his PR team, and being a single father on top of that left little time to care for himself. His ex-wife was no help either. She never took their daughter out, never paid child support (not that he really needed it), and never even really saw her. He was running on fumes with no help whatsoever.
So that's why he was so relieved when his agent recommended your nannying service to him.
You were one of the top nannies in Japan. You had worked with some of the most influential politicians, heroes, celebrities, and business owners all over the country. And your resume spoke for itself. The elites had nothing but glowing reviews of your services. Not only did you adhere strictly to the (albeit sometimes wild and deeply unnecessary) rules that the families had laid out for you, but you genuinely cared for each and every child that was placed under your care. You connected with them: listened to them talk, asked them questions about their hobbies, played with them, learned their favorite foods, and even remembered the names of everyone important to them.
Needless to say, when his agent offered to contact you and set up an interview between you two, he agreed almost instantly.
You arrived at a large, modern-style estate in a simple sundress and a shawl. Nothing too flashy, nothing too expensive. You had learned after almost a decade of nannying, you had learned that modest is better. You had always been naturally curvier, which, in the beginning of your career, caused some parents to doubt your intentions when coming into their home. Husbands thought you were a bad influence on their young, impressionable daughters. Wives thought you were there to try to seduce their husbands. In reality, you were just trying to get paid. Nothing more.
After ringing the doorbell, the pro hero opened the door and smiled at you.
“Welcome in,” he said, offering his hand for you to shake. “I’m Ejirou Kirishima, but I’m sure you already know that.” You grabbed onto his hand and gave it a firm shake as you introduced yourself.
Upon meeting you for the first time, Ejiro realized two things.
Firstly, his daughter was going to be in good hands.
And secondly, it was going to be very hard to keep his hands off of you.
“It’s nice to meet you, (l/n). Come in, and we can get started.”
He led you into the dining room and pulled out a chair for you and gestured for you to sit. Impressed by his chivalry, you couldn’t help but blush as you thanked him.
“No need to thank me, miss. I’m pretty sure I’m supposed to give you a little interview now, aren’t I?”
His voice was nonchalant, a welcome change of pace from the clients you usually took on. You nodded expectantly and watched as he sat down in front of you at the table.
“So, to start off, I just wanna tell you a bit about my daughter,” He started. Oh, right. You actually didn’t really know anything about his daughter. While Red Riot was a popular hero and celebrity, he drew a sharp line where his public life ended and his personal life began. His ex-wife, a civilian, not in the hero business, was only known to the public by her first name. She rarely went out with him. There were very few photos of her floating around the internet, if any at all. The only reason people knew they had divorced is that he got his tattooed ring covered up. “But first, I’ll have you sign this NDA. Not cause I don’t trust you or anything, but just so I can say I did.” His daughter was even more of a secret. No one knew when she was born, what she looked like, or even her name. Ejirou was fiercely protective of her privacy and made it abundantly clear that he would not be revealing anything to the public anytime soon. He was a loving, protective father who would stop at nothing to protect the ones he loved.
And that was part of what was so sexy about him.
You quickly skimmed over the NDA. It was pretty basic. All it really said was you were not allowed to repeat any private information you hear pertaining to his home life. That included family members, close friends, as well as any individual you came into contact with or had only heard about because of him. You quickly signed it before sliding it back over to him with a small smile. He took it from you and began sharing.
“Her name is Kanako. Shes four and a half, and she’s honestly kinda crazy. She’s got crazy energy, gets it from her auntie Mina. Have you ever worked with smaller children before?”
“Yeah, I have! I've worked with a lot of toddlers, actually.”
He seemed impressed by that and smiled at you.
“Great, so you’ll know what to expect! Cause well, she’s pretty wild.”
You smiled and laughed. You were used to kids like that, chaotic toddlers who were constantly screaming and did anything but listen. You knew how to handle them.
“Oh, that’s alright. I’ve dealt with my fair share of crazy kids. I’m more than ready to handle it. Could you tell me some of the expectations you have for me? Like, things that you want me to be in charge of?”
“As long as Kanako gets taken care of and fed, that’s all I really care about,” Ejirou shrugged slightly. “I just want to make sure she’s getting attention when I’m away. I have people to watch her, but she doesn't really connect with them, you know? She’s a bit shy around people she doesn’t know that well. I just figured it would be nice for her to have someone who's always here.”
You nodded at that. That was the very reason most families hired nannies. Normal babysitters usually weren’t consistent enough to truly connect with the child, since they usually had a rotation of clients that they’d only see every so often. With a nanny, especially a live-in, like you were, the child got undivided attention.
After a few more logistics questions, Ejirou smiled.
“When can you start?”
You blinked at that. You were definitely a top nanny, but you usually weren’t just hired on the spot. Most families interviewed others before selecting a nanny. But, with a high-profile client like this, you knew not to look a gift horse in the mouth.
“Uhm, I can quickly pack my stuff and be ready tomorrow, if that works for you?”
“Really? That’d be great, actually! Cya then!”
…
After starting the next day, you actually barely saw Ejirou. He was constantly gone working, and when he was home, he was usually sleeping. You didn’t mind, however. It was fairly normal for the parents you worked for to be gone a lot. Instead, you focused on little Kanako. He was correct; she was incredibly shy the first day you watched her. However, the more time you spent with her, the more she opened up. She was a little crazy sometimes, admittedly, but you loved her all the same. She was constantly running and jumping around, and when she wasn't doing that, she was saying things that made you question your sanity.
“You look like mommy! Are you my new mommy?”
You tried to correct her, but the toddler was incredibly insistent. She began calling you mommy.
A few weeks had gone by, and you were mostly settled into your routine. Honestly, the hardest part of high-profile clients was the houses. They were so big and stupidly hard to navigate.
Which is why, one night, after getting up for a snack. You ended up opening the door to the wrong room. You opened the door, expecting the sight of your cozy, dark room with your phone in the bed.
Instead, there was a man there.
Pro hero Red Riot.
And something else was red in that bed. And that something else was big.
Ejirou was lying in the bed, with his laptop on his chest and his cock in his hands. On the computer screen, some porno was playing quietly. You couldn’t help but notice that the female actress bore an almost uncanny resemblance to you.
As soon as the light from the hallway entered the room, Ejirou’s eyes shot over at you. You hadn’t been prepared to see anyone, much less him, and it showed. You were wearing a bralet that barely did anything to obscure the view of your tits, and baggy sweatpants that hung a bit too low. When his eyes finally met yours, you immediately began apologizing and went to close the door. But before you could close the door, he stopped you.
“Wait. I could use some help…”
You swore you almost felt your soul leave your body. Help him? You couldn’t. You shouldn't.
It was in your agency’s contract. You were forbidden from having sex with the parents of the children you were nannying for. Just because this time, you were nannying for a sexy dilf who clearly thought you were his type didn’t change that. You prided yourself on your professionalism.
“Uhm… I’m uh, not really allowed to.. Y’know.. I can’t really fuck a parent…”
“I’m not asking for you to fuck me… just, asking if you can lend me a hand… or a mouth…”
Shit. You couldn’t argue with that logic. Or, well, your cunt couldn't.
You slowly approached the bed and got on your knees. He immediately closed the laptop and sat on the edge of the bed. The real thing was way better than anything he could find on that shitty porn website anyway.
He pressed the tip against your lips as he waited for you to take him in. You pressed a few kisses into it before slowly opening your mouth and allowing him to slide it in. It was a bit of a stretch, but you made it work. He allowed you some time to adjust, his hands finding their way to your hair as he whispered to you.
“You know.. This was all I was thinking about the day that I hired you...”
As soon as he could tell you were comfortable, he began violently thrusting into your mouth. It was a complete 180 from how gently he had just been. It would’ve scared you if it wasn’t so sexy. His pace was almost animalistic, clearly pent and frustrated. He was tired of being gentle.
“So good… such a good mouth for me…”
You moaned as he continued to abuse your throat, which only made him go harder. He grabbed your hair and guided your head so fast, you genuinely thought you might get whiplash.
“That’s it… Take it like a good girl...”
As he got closer and closer to climax, he only got rougher. He was fucking your mouth so hard, you could hardly breathe. It was a miracle that you hadn’t choked. He began groaning more and more as you continued to work, his hands still vigorously guiding your head.
“Gonna cum.. You better swallow all of it, okay…?”
His voice was soothing and gentle, a sharp contrast to the sharp and fast way he was destroying your throat. After a few more hard thrusts, he came in your mouth, warming the back of your throat after he had just fucked it raw. A bit dribbled down your chin as you swallowed it, before you stuck your tongue out to prove you did what was asked. He slowly stood up and helped you off your knees before pulling you into a kiss, tasting himself on your tongue. He broke away from the kiss for a moment to whisper to you.
“Keep this up, and you won’t ever stay in your own room again...”
You silently prayed he’d follow through with that threat as he began the kiss again.
