(A/N: 3k words, wew.)
Mitsuki was walking back to her home slowly. She was still lost in her thoughts, the previous event took a lot of toll on her mind.
The kiss Izuku forcefully took from her was still vivid in her mind. Despite the fact that he was rough, she found pleasure in him. Maybe because it was immoral, maybe because it had been too long, or maybe Izuku was actually bringing her pleasure...she couldn't think of a reason.
Mitsuki was greeted by a dark and dim hallway when she opened the door to her house. When she turned on the lights, she discovered clothes and other items scattered across the front floor.
'Fucking Katsuki. Why did he even run if he's going home anyway,' Mitsuki cursed. If Bakugou hadn't run away from her, then she wouldn't have taken her time returning home, then she wouldn't have met with Izuku, then everything would've been fine.
Everything would've stayed the same.
She could still hang out with Inko in the future without feeling guilty. She wouldn't have to behave differently around Izuku. She would not... She wouldn't have to pretend she didn't like his intimate advances.
'Masaru too, always with work…' Mitsuki trailed the curse along to her unsuspecting husband. Ever since Izuku gaines his quirk. Katsuki's increasingly explosive behaviour stifled a rift right into their relationship.
She soon shook her head. Thinking about the bad things will only drive her to desperation and cause her to do stupid and regrettable things.
With a sigh, she cleared Katsuki's mess from the floor. She noticed several small wooden splinters piercing the fabric as she picked up his uniform. Bakugou was not hurt, according to Izuku, and it looked true since there was no blood bleeding out.
Mitsuki went into Bakugou's room and placed his bag inside. She knew it was around the time he worked out and that he should be in the garage.
When she got to the garage, loud music blasted into her ears as she saw Katsuki lifting weights. Mitsuki turned off the bluetooth speaker, which caused Katsuki to frown as he exclaimed, "OI! "I'm working out right here!"
"Shut up," Mitsuki said, exasperated by his attitude. She witnessed him being thoroughly beaten by Izuku, but she couldn't understand why he was still so egoistic. "Did you get hurt in today's fight?"
Bakugou stopped lifting his weights and stared at Mitsuki. He tried his best not to get pissed as he remembered today's embarassment of a fight. He couldn't even burn an inch of Izuku's skin, much less beat him.
"None of your business old hag," He snarled
Mitsuki couldnt be bothered by him anymore. All she wanted was for him to talk to her, or ask for help, anything, but he didn't. Bakugou was too much in his head that he couldn't even notice her complicated and pained expression.
"Don't be late for dinner. Your father will be home soo–," Suddenly, Mitsuki received a text saying Masaru will be home late.
'...Is the world trying to kill me?! Today of all times?!' Mitsuki silently cursed the unfortunate coincidence. She's already trying her hardest to be content with what she has, but why...why has this all happened now?
"Katsuki…Your father will be late. Do you want to eat out with me?" Mitsuki was desperate. That was the end of it. She couldn't take it any longer, and if Katsuki refu-
"No," Bakugou flatly said, "Turn my shit on and get out, I'm really pissed right now,"
"...I'll eat out by myself then; tell your father not to wait for me," Mitsuki sighed and walked away.
Bakugou had no idea why, but he thought he heard a line snap. He quickly ignored it as he enjoyed the return of his music, not minding the sound of his mother leaving

Izuku was wiping away sweat from his workout when he heard the doorbell ring. To say he was surprised to see Mitsuki return was an understatement.
"Did you forget something, Aunt Mitsuki?" Izuku inquired. He then remembered she had forgotten her bag from when she first arrived and said, "Right, I'll take your bag–"
"...Shut up and listen," Mitsuki was enchanted by his topless body, but she quickly snapped out of it and said, abruptly stopping Izuku, "I don't know what the fuck is going on, but I'm really down to do something I'll definitely regret when tomorrow comes,"
"Wait, wha–" Izuku asked, perplexed, before coming to a halt. He, couldn't for the life of him understand the development of the situation, but, he couldn't care less right now and immediately stopped trying to comprehend it, instead, he smiled before saying, "Come on in then, Mitsuki~,"
~~~~~
"Give me it Izuku! I need it!" Mitsuki screamed at the top of her lungs as she leaped towards Izuku, pressing her chest against him. Izuku took advantage of the situation, shamelessly holding her waist to draw her closer.
"No, it'll only make the night worse," Izuku shook his head, not giving up.
"I really need the alcohol so I can blame it for today!" She continued to reach for the bottle of alcohol Izuku was holding, unaware of the joy she was causing him.
"As you said, Mitsuki, just blame the shitty world. Alcohol will only make you enjoy today and tomorrow less," Izuku said, setting down the bottle of alcohol and picking up Mitsuki by her legs.
"Eep!" Mitsuki yelled, "Put me down! Izuku!"
"Sure," Izuku said, smiling, and Mitsuki immediately regretted her words when she saw where he was taking her, "nonononono! It's way too early!" She yelled.
Izuku didn't back down and carried her over to his bed, where he pushed her down.
It was the exact same position they were previously in, with Izuku pressing his topless body against hers, but this time, Mitsuki was fiercely blushing with an expectant expression donning her ferocious face.
Izuku couldn't hold it back anymore when he saw her darting her gaze away from him. If did it out of fear before, she was now only doing it out of embarrassment. With his left hand, he cuffed both of her hands above her head, exposing her entire body to him, and dove into her lips.
Mitsuki realized there was nothing she could do to stop the boy in front of her anymore. There was nothing stopping her from doing so either, so she reveled in the bliss he was about to bestow into her body.
Mitsuki felt the ever-so-familiar lips connecting with hers once more. She opened her mouth and followed suit, feeling extra sweet now that she wasn't resisting. She didn't want to lose to a boy, especially not when it was his first time and counterattacked.
Izuku felt her tongue blocking his path and decided to play with it instead. He entwined their tongues together, causing a sloppy atmosphere to appear in the room the two shared.
When he kissed Toga, it was all him doing the work. With Mitsuki, however, he could feel her sucking his tongue and saliva just as greedily as he did. Mitsuki was clearly not going to relinquish control to him, but neither will he.
He continued sucking her tongue and lips as she did his. They only separated to catch a whiff of each other's breadth before returning to fully indulge in their most carnal desires.
Izuku and Mitsuki couldn't be satisfied with just this. They saw each other's desire as they kissed and stared within each other and let go of the kiss. Izuku undressed Mitsuki quickly, ripping her clothes off forcefully and tearing them to shreds.
She couldn't care less because she also stripped off the rest of his clothes, exposing his most vulnerable part. Mitsuki couldn't help but compare him to her husband, but she quickly dismissed the thought. She didn't have a husband right now, and the world was filled with Izuku and her alone.
"It's decent, right?" Izuku said with a cheeky grin as he removed Mitsuki's underwear, exposing her fully. "I'm surprised you let it grow this much," he snickered, noticing her most intimate parts were still covered by a thick layer of blonde natural hair.
"Shut up!" Mitsuki glared angrily as she grabbed Izuku's dick with some force, causing him to tense up. "I hadn't done it for months. Why would I shave just for today?"
Although Izuku wanted to complain about her rough way of her handling his little friend, her words caused him to swell up instead,
"Really? I'm surprised your body would be this deserted. I'd love to eat you every day if you were my partner," Izuku smiled and kissed her neck. His fingers slowly caressed her hairy cave, trying to get her even further into the mood.
"Mnnn…" Mitsuki let out a small moan after feeling Izuku's gentle touch, "Being an adult is hard you know. We can't just do it every day without any consequences," Mitsuki said before slowly rubbing his little friend as well, returning the favor.
This was his first time being this riled up in this world and Mitsuki's touch almost made his mind go blank. He slowly rose from her body and decided it was due time.
"Let's put all that aside later…" Izuku said. His voice was huskier than ever as he rubbed his friend on top of Mitsuki's bushy cave. He sucked in a deep breath of tingly pleasure as he felt her blonde hair brush against his.
Mitsuki couldn't help but laugh after seeing Izuku's eager expression. She had never seen him this excited about anything else before and smiled. Though, Izuku could say the same to her as he saw the anticipation in each other's eyes.
"Ready?" Izuku asked, connecting the tips of their parts.
"I should be the one saying that you brat," Mitsuki chuckled. Even though it was his first time, he was the one who asked if she was ready.
"Okay then, here I g—"
"FUCK! STOP!" Mitsuki yelled, backing away, "Put a fucking condom first! It's a very dangerous day today!". She was half sure Izuku would cum immediately when he slide it in and sucked a deep breath after realizing the blunder.
"But I don't have one," Izuku grumbled as he scratched his neck in frustration.
"Don't Inko have some here?"
"Fuck no!…" Izuku said. He immediately realized his error as he let his possessiveness towards Inko out, "I think…"
Mitsuki didn't bother and said right away. "Go downstairs, there should be a store that sells nearby,"
"Now? But I'm already this hard," Izuku said, holding his dick in front of her. Mitsuki couldn't stand it anymore since she, like him, wanted to do this as soon as possible as well, "After I do this, you better go buy some!"
Mitsuki pushed Izuku down on the bed and lay down without waiting. He could feel Mitsuki's soft hands rubbing his dick as she slowly slid the whole thing into her mouth, deep-throating him immediately.
'Oh fuck…you don't immediately suck the whole thing in!' Izuku complained inside, though his current expression stated otherwise as he slowly rubbed Mitsuki's rather prickly yet soft head and guided her rather fierce blowjob.
Although Izuku really wanted his first load out in this world to be inside someone's vagina, letting it flow into someone's mouth comes in a close second. Izuku couldn't hold on for much longer and kept her head locked in as he came.
"Fuck...sorry," Izuku apologized as he let go of her head. Mitsuki was choking on his cum as a large portion of it flowed out of her mouth and dirtied her entire body. Izuku gulped in her current orgasmic appearance, some even reached dirtied and enchanted her no-no place.
"5 minutes or we'll call it quits," Mitsuki said as he slapped his semi-hard dick as revenge. Her throat now felt as sore as a desert whenever she tried to regain her composure.
Izuku wasted no time in taking whatever clothes he could find and going down to the nearby store. He didn't care if anyone saw him jump down from the fifth floor and basically fly at supersonic speed toward the nearby drugstore.
Mitsuki looked at Izuku's frantic expression as he left the room and a smile bloomed on her face. She liked this Izuku a lot.
Mitsuki felt something on her face and licked the last trace of cum from her lips before swallowing it whole. 'I might get addicted to this boy…this is so dangerous,'
…
Izuku returned not even five minutes later, ripping his clothes off with his quirk, causing Mitsuki to giggle. He threw a row of pills at Mitsuki, who looked at him strangely and asked, "Don't they have any condoms?"
"I want to cum inside,"
"...fair enough," Mitsuki shrugged as she looked at the pill, unable to refute his solid argument. She also wanted to feel him inside her womb after being covered by his stuff not long ago.
"If this doesn't work, I'm expecting you to be a rich hero and take me in you cheeky brat," Mitsuki joked as she took a pill and threw the rest away.
"Now come," Mitsuki beckoned Izuku as she parted her legs and spread her vaginal walls open for the world to see, "I want you in, now,"
Izuku didn't bother to wait or do foreplay any longer. At this point, he was already at his limit of tolerance and couldn't wait any longer.
He guided his tip into her hole as they returned to their previous position. His dick fits tightly into her vagina before he went in in one fell swoop, like a key forcefully sweeping into a lock.
"MNnh!" Mitsuki yelled, not expecting the boy to immediately shove his entire dick in one go. She glared at Izuku as she felt a tingling pain from his forceful entry. However, before she could complain, the next wave of attacks already began as Izuku shoved his dick in and out of her without mercy.
"Slow down, Izuku..." Mitsuki tried to reason with him, but the pleasure was too strong for her to form a coherent sentence. She couldn't stop thinking about the constant wave of pleasure that a boy, no, a man was giving her. It was as if she had finally been cared for and loved.
The warm and tingling sensation around her legs and belly pushed away all thoughts of guilt and regret. His warm body pinned her down, reminding her of who she only needed to think about right now.
It was as if the previous imprint her husband had left on her had faded. She relished the length and girth of his little friend as her walls gradually morphed into his shape.
Izuku let his hands run wild, caressing her surprisingly smooth skin for a woman her age. As he found a better angle to plow her in, he lifted her legs up on his shoulder and caressed her glowing thighs.
"Izu–Izuku…" Mitsuki softly yelled, looking at the boy's greedy eyes and pulling his head in for a kiss. She wanted to fill the void left by her lack of words by allowing his tongue to freely roam into her mouth.
Mitsuki changed the position and sat up on his lap, giving him a better opportunity to hug and feel her entire soft body as he went in and out without tiring. Because of all of his training, Izuku's stamina was insanely high, and he felt like he could do this all day.
"Mitsuki, I'm cumming," Izuku said abruptly, prompting Mitsuki to tighten her walls even more as if she didn't want any of his proof of love to seep out.
"Cum together Izuku…let it all inside me!" Mitsuku yelled as she nestled Izuku's head on her chest, allowing him to enjoy her breasts while he cummed inside.
"Nghh…" Mutsuki moaned as she felt a massive amount of gooey liquid seep into her womb. Her body quivered like never before as a result of her own orgasm. She had long forgotten the sensation of someone releasing everything inside her, and she couldn't help but kiss Izuku passionately once more. She wouldn't let him go until she had extracted everything from Izuku.
The two lips separated as Izuku went in for another quick tap, cleaning the trail of saliva they left behind and letting out a content smile. It was his first time doing and letting it out in a woman, and he was glad that woman was Mitsuki.
Mitsuki was happy as well because when she saw his smile, she couldn't help but imitate it and give him a chaste kiss before asking, "Is this really your first time?"
"It is. Aren't you glad you're my first? Because I am," Izuku said truthfully.
"Cheeky little brat," Mistuki said again, this time with a sly grin. "I'm not sure why you'd be happy with an old woman like me, but I'll squeeze you until you regret it," she says.
"Haven't I told you the reason before? On the couch?" Izuku asked.
"Those weren't a ploy?" Mitsuki asked back. She assumed that everything he said, every sweet word he uttered, was just a line he wrote to get her to bed and nothing more.
"Ugh, I really do see you as a beautiful and kind woman you know, and there's a reason why I kept aiming for you even when you were mom's friend," Izuku said, diving his body and snuggling deep into her chest as if he was really hurt.
Mitsuki felt somewhat guilty since she really didn't believe him at first. "Fine, I'm sorry. That make you feel better?" She said, patting his head softly and letting him enjoy her chest.
"No." Izuku lifted his head and said, "I want, no, I need you to do this to make me feel better," Izuku showed a devious grin as he whispered into her ear.
Mitsuki immediately flushed as she slapped his head hard, "What kind of shit are you asking an old woman like me to do! I'll die of embarrassment if I do that!" She yelled.
Izuku only pouted as he dove back into her chest, depressedly saying, "I guess Mitsuki still doesn't trust me enough. I'm so hurt..."
"...fine, I'll do it the next time we do this," Mitsuki said, unconsciously trapping herself in another day of lovemaking with Izuku. Or maybe it was planned, only she could know.
Mitsuki slowly backed away as his penis slowly came back into view. She used her hand to clean his penis before doing the same to her now-sticky vagina. As Izuku's cum leaked out, the blonde bush was now layered with a subtle hint of white.
When she felt his penis leaving her, she moaned a little. Her body was truthful, and it only increased her desire for him. "Don't tell me you're done," Mitsuki said, looking down at Izuku's now limp dick.
"I need a while," Izuku smiled wryly, "I'm not strong enough since this is my first time, but my quirk enhances my regeneration so I'll be ready in a minute,"
"So, in the meantime," Izuku said as he pushed the unsuspecting Mitsuki back down. She felt his hands begin to play with her dirty bush as his lips sucked on her right nipple, bouncing her breast up and down. Mitsuki relished his every touch, almost cumming again due to her increased sensitivity.
Mitsuki wasn't sure why she let him freely indulge in her body like that, but by the time she looked back at Izuku's little friend, he was just as eager to go as she was.
She wasn't sure how long Izuku could keep this up, but she silently hoped that this little secret endeavor of theirs would never end.

(A/N: Ngl, I enjoyed writing about Izuku's relationship with Mitsuki way more than their sex scene. I think it was obvious since it took me 9-10k words to reach their sex scene lol. It was nice as a payoff/treat, sure, but I don't think I'll do them that often.)
