But, boy, I need to get you off of my mind (off of my mind)
I know exactly what I have to do
I don't wanna be alone tonight
Rhythmic beats and grinding bodies surrounded Izuku Midoriya as he awkwardly tried to move to the music in the club. Places like this were not typically his scene but after wallowing in his apartment alone for months following his break up with Kacchan, some of his friends dragged him out for a night of drinking and dancing. It was supposed to be a fun distraction. A night where his friends kept him company and cheered him up. But half an hour into the night, Todoroki had bumped into an old flame and was now furiously making out with Inasa Yoarashi against a wall.
Ida, bless his heart, was probably more uncomfortable than Izuku. He stood stock straight at the little bar table, nursing a sapporo beer, watching from the sidelines. Izuku had tried to tell him that he didn’t have to come to the gay club if it would be too much for him but Ida had insisted on being there for his friend. After the fourth guy tried and failed to hit on his bespectacled, heterosexual friend, Ida bowed out. Literally bowed before fleeing, leaving Izuku alone once again.
And Shinso? The flakey son-of-a-bitch didn’t even show up even though he’d agreed to meet them there.
Well… they tried. Sort of.
Izuku didn’t really want to be here anyway. He was still raw from how things ended with Katsuki. Walking in on him and Kirishima in their bed after finishing patrol early had been a nasty surprise. It had taken them a full minute to even notice Izuku was standing there, frozen in shock with tears silently streaming down his face. Izuku could still see their sweaty limbs all tangled together every time he closed his eyes. No amount of dancing or drinking was going to erase that image from his mind.
The sad thing was, Izuku could have probably forgiven Kacchan for cheating. He had loved him that much. But it was overhearing Katsuki tell Kirishima he loved him while in the throes of passion that destroyed Izuku. Kacchan had never once said those words to Izuku in the few years they’d been dating. He used to dismiss it as Kacchan being unable to communicate how he really felt, telling himself that actions spoke louder than words. But now he knew the truth. Izuku had just been a placeholder for who Katsuki had really wanted.
Just as Izuku considered leaving the club and going home, back to his empty apartment, a hand wrapped around his waist as someone’s hips began grinding up against him from behind. He was sober enough to know that this probably wasn’t the smartest thing to do and just tipsy enough to not care. The club was dark and the hat he had on was covering his famous green curls. Most fans didn’t recognise the hero Deku without his costume on anyway so he felt pretty confident no one would recognise him here. Why not enjoy the feeling of some stranger dancing up against him? It’s not like he had a boyfriend anymore… no one cared what he did or who he did it with. Izuku allowed himself to get lost in the feeling of having someone dancing behind him, strong hands pulling him closer until his back was flush against the man’s chest.
The longer they danced, the bolder the strangers' hands got exploring Izuku’s body. Every touch from the stranger was charged; Izuku’s skin buzzed with an electric pleasure he hadn’t felt in so long. Soon a hand slid underneath the hem of his shirt and brushed against one of his nipples. Izuku encouraged the touches by wiggling his ass against the man’s crotch, noting with pride the hard erection he could feel rubbing between his cheeks. The man’s hot breath tickled Izuku’s neck before he felt lips kissing and sucking the sensitive skin there.
A hard bite combined with a firm pinch of his right nipple had Izuku gasping. Blindly groping at the man behind him, Izuku searched for something he could squeeze in response. His left hand found the stranger’s toned ass cheek and he playfully kneaded the cloth-covered flesh while they continued to grind up against each other. The hand that had been holding Izuku’s hips close to the man’s body moved south and started tentatively rubbing a finger along the growing tent in his pants.
When Izuku bucked his hips up into the touch with a moan, the hand got more daring, palming his hard-on vigorously, using the pressure to push his ass back into the stranger’s own erection. A small whisper of sanity reminded Izuku that he shouldn’t be doing something like this in public. He was the number one hero in Japan. If someone did manage to recognise him, the fallout from the press would be bad. But as the stranger’s hand moved with skill and purpose against his hard length, Izuku found it impossible to care about anything else.
It was strange letting someone who wasn’t Katsuki touch him like this. He’d never been with anyone else. Never wanted to. Now here Izuku was - single and allowing a complete stranger to rub him off in the middle of a dance floor. Whoever they were, they were very good at it. Better than Kacchan, a small voice in the back of Izuku’s mind noted. He felt guilty at first for thinking that before angrily reminding himself that he had nothing to feel guilty for. He wasn’t the one who cheated. He wasn’t the one who betrayed the other’s trust and broke their heart.
That flash of anger overrode the last of Izuku’s shame and he recklessly grabbed the wrists of the stranger and pulled him towards the darkest corner of the club, where they could get away from prying eyes. The man didn’t miss a beat. He was on Izuku the moment they made it to the corner, kissing and groping with a hunger Izuku wasn’t used to when it came to love making. Maybe that should have tipped him off years ago. Katsuki’s interest in that aspect of their relationship had dwindled in the last year but it had never been this heated in the first place.
Izuku turned around to try and get a look at the stranger he’d been grinding up against, but the corner of the club they’d retreated to was so dark and smokey, all he could get a glimpse of was dark long hair and darker eyes. Something about it felt vaguely familiar but Izuku’s drunk mind couldn’t focus. The stranger pulled Izuku in close and kissed him full on the mouth. It felt nothing like kissing Kacchan and for that, Izuku was exceptionally grateful. This kiss was surprisingly tender after all the dirty dancing the two men had been doing. Soft lips mixed with the feel of stubble against his skin was oddly intoxicating.
Before long, hands were everywhere again, getting more frantic as the kisses grew more heated. The stranger started tugging at Izuku’s belt with a deep growl, making his skin break out in goosebumps. Nimble fingers had his belt and zipper undone within seconds and were now urgently wrapping around Izuku’s leaking cock. Izuku thrust up into the firm grip, kisses getting sloppier as the thrill of being jerked off in public broke his concentration.
Then the stranger pulled his own dick out and held both cocks between his big hand before stroking them simultaneously. His free arm wrapped around Izuku’s waist, making it look like the couple were still dancing to anyone who may happen to glance their way. Moving in time with the music, the two men rolled their hips up together, chasing their orgasms with fervour. As the music swelled, they too reached their own crescendo. Izuku climaxed first, hot cum spilling over the stranger's fist, becoming lubricant for his hand. The stranger followed quickly after, groaning his name in a deep voice.
“Izuku…”
He froze as recognition finally sunk in.
That voice…
Izuku knew that voice!
It was no stranger.
It was Aizawa-sensei!!
Well, not his sensei anymore. The man hadn’t been his teacher in two years. But still… how had he not realised sooner?!
Confused. Embarrassed. Aroused. Mortified. Izuku pushed away from his former homeroom teacher and quickly tucked his dick back into his pants.
“Izuku? What’s wrong?” Aizawa asked, sounding just as confused as Izuku felt and maybe even a little hurt?
“S-sensei… Eraser… I mean Aizawa… I-I-I h-have to g-go…” Fighting off tears, Izuku turned and bolted, resisting the urge to use One for All to move quicker through the crowd which would only draw more attention to himself.
What the hell have I done? I just got off with my old teacher… who is an incredibly good kisser… no! Stop! I can’t think about him like that! We do hero work together for fuck sake! I can’t be thinking about how sexy his voice sounded when he moaned my name as he climaxed. Shit! Stop thinking about it, Izuku! Damn it, my head is a mess… I need to leave. Now.
As Izuku pushed his way through the densely packed crowd, he bumped into Todoroki and Yoarashi, who were still busy sucking face. His friend must have noticed the distressed look on his countenance because Todoroki finally tore himself away from his on-again off-again lover and chased Izuku outside, into the cool air.
“Midoriya? What happened?”
“N-nothing. I’ve had enough for one night so I’m going home.”
“It doesn’t look like nothing. Where’s Ida?” Todoroki looked around for their tall friend.
“He left. Ages ago.” Izuku let his hurt, anger and confusion bubble to the surface as he yelled at his friend.
“Oh. Sorry… we were supposed to be cheering you up and I let myself get distracted. Need me to get you a taxi or something?” Todoroki said contritely.
“I’ll make sure he gets home safe.”
Izuku whirled around with wide, teary eyes to see Aizawa standing there, looking a little disheveled; his intense gaze laser focused on him. It was strange seeing the hero in a tailored black suit with a purple paisley shirt, slightly unbuttoned down his chest. He looked… hot.
“Aizawa-sensei? What are you doing here?” Todoroki looked surprised and curious at their former teacher's presence at the club.
“I was out with an old friend when I spotted you,” Aizawa spoke directly to Izuku, not even glancing in Todoroki's direction, “Can we talk? Please?”
“…Okay.” Izuku swallowed thickly before turning to Todoroki, “I’ll see you back at the agency Monday morning, alright?”
“Sure…” Todoroki’s eyes flicked back and forth between Izuku and Aizawa, trying to figure out what had happened when he wasn’t looking.
Aizawa flagged them down a taxi. When the automatic doors opened for them, he gestured for Izuku to slide in first before joining him in the backseat. Izuku gave the driver his address before turning to face Aizawa.
“I’m sorry. I thought you knew it was me…” Aizawa apologised in a low voice, “When you dragged me over to the corner and stared at my face, I thought you recognised me then. But I must not have made it clear enough. Forgive me.”
“N-no! I’m sorry! I was drunk… still am a little… and I just wanted to forget about… stuff… and I didn’t care what I did or who I did it with. But I would never want to ruin the friendship we’ve built and the working relationship we have over a stupid drunken dirty dance.”
No matter how nice it felt…
“It did feel nice.” Aizawa said in a way that made Izuku’s heart skip a beat.
Oh. I must have said that aloud.
Seems like his filters were still gone thanks to his inebriation, but then… he hadn’t had anything to drink in a while and Izuku burned off the effects of alcohol quicker than most thanks to his quirk. So what was making him act like an idiot?
“Y-yeah… It’s too bad we shouldn’t have done it…” Izuku whispered as he subconsciously began leaning towards Aizawa.
“Mmmm. Better not repeat it again…” Aizawa drifted closer to Izuku.
“That… would be… bad…” Izuku’s shoulder was now touching Aizawa’s and their breathing was getting heavy.
“Completely irrational…” Aizawa’s breath was close enough that Izuku could taste it on his tongue.
“Never again.” Izuku closed the distance between their mouths and kissed Aizawa feverishly.
They made out in the back of the taxi the whole drive to Izuku’s apartment, breaking for air long enough to pay and climb out before stumbling their way through the foyer, to the elevator and up to Izuku’s floor. It was a tricky thing, getting the front door unlocked while Aizawa busied himself covering Izuku’s neck in hickeys. Despite having already cum once tonight, Izuku was already rock hard again in his pants. It was liberating to just strip off everything and throw articles of clothing haphazardly around the place, making the apartment messy. Kacchan hated mess.
“Shall we take this to the bedroom?” Aizawa asked between kisses.
Flashes of Katsuki and Kirishima fucking on that very same bed popped up in Izuku’s mind, making him cringe.
“N-no… not the bed. Anywhere else is fine. Just… not there… please.” He hadn’t even been able to sleep in his own room since it happened. He should probably just move, get a new place without awful memories haunting him but Izuku didn’t have the time or energy to go apartment hunting. Not to mention the added cost of breaking the lease contract early.
“Of course. Whatever you want, Izuku.” Aizawa went back to kissing him in such a way that made his head go all warm and fuzzy, banishing every unpleasant thought from his mind. Then he was being guided to the couch, laid down on his back while Aizawa settled on top of him.
“Do you have lube?” His former teacher asked.
“Oh… shit! No… K-Katsuki took all of that with him when he… left…” Izuku did his best to not let his voice break when saying his ex’s name.
“Don’t worry! That’s fine. We don’t need it.” Aizawa flipped Izuku onto his stomach with a lop-sided grin and without warning, began to eat him out.
Izuku squeaked bashfully. How could Aizawa do this so casually? Kacchan never did anything like this. It was too dirty! Izuku couldn’t help the guttural moans that escaped his lips as Aizawa swirled his tongue around the edge of his anus. He was eating him out like a starved man, making sounds that went straight to Izuku’s dick. Never in his wildest imaginings did Izuku ever think he’d be here, getting tongue fucked by his former homeroom teacher.
When there was enough saliva to act as lube for Aizawa’s fingers, the hero began to ease one into Izuku’s entrance slowly, making circles and scissoring motions as he moved in and out to stretch and loosen the muscle around the rim. By the time his old sensei had three fingers inside of him, Izuku was leaking all over his couch and panting heavily. If Aizawa didn’t hurry up and fuck him soon, he was considering climbing on the man’s lap and impaling himself on the erasure hero’s cock.
“Ready?” Aizawa asked, voice rough with need.
“God yes!”
Spitting on his hand, Aizawa did what he could to make his penis as slick as possible before sinking into Izuku’s heat. It was still a little rougher than what he was used to without lube but not terrible. Somehow, the raw feeling of nothing artificial between them was incredibly hot. Izuku could feel every inch of Aizawa as he pushed deeper and deeper, stretching him further than ever before.
Once Izuku adjusted to the feeling of Aizawa inside him, his old teacher began to move, dragging his length over that one spot that made Izuku keen every single time. His thrusts were slow, deliberate, gentle. Driving Izuku mad as heat coiled in his belly at a slow but steady speed. Aizawa seemed to pick up on his frustration and leant over to take Izuku’s cock in hand, stroking it in time with every thrust.
“Yes, yes, yes…” Izuku chanted, mind going wonderfully blank as he allowed his instincts to take over.
“Feel good?” Aizawa breathed in his ear before nibbling on Izuku’s earlobe.
“Amazing… don’t stop!” Izuku begged.
“Oh, I don’t plan to.” Aizawa sounded smug.
Izuku didn’t know how the man did it, but Aizawa managed to keep finding every spot on his body that made him melt. It was like he knew Izuku’s body better than himself. Sex had never felt this all-encompassing before. It was probably a little unfair to keep comparing everything to Kacchan but it was the only point of reference Izuku had for this stuff. His ex-boyfriend wasn’t terrible at sex but Aizawa… he was... a savant!
His limbs began trembling as the beginnings of an orgasm worked its way through Izuku’s body. Eyes rolled into the back of his head as Izuku lost control of his quirk momentarily, green lightning dancing across his skin making the lounge room light up in its glow.
“Ahhhh fuck! You’re squeezing me so tight!” Aizawa moaned, speeding up his movements and driving Izuku wild.
“I’m close! G-gonna… gonna cum…”
“Not until I say so, problem child.” Aizawa ordered, activating his quirk and extinguishing One for All in the process. Izuku couldn’t help but shiver at his tone, clenching down even more on his former teacher’s cock.
“Please! Sensei… let me cum!” Izuku begged.
Aizawa’s movements faltered for a moment at those words before he picked back up with a breathless curse, sounding just as close as Izuku was now. Their motions, their breaths, their very heartbeats were in perfect sync. With a choked whisper, Aizawa gave Izuku permission to finish and the two of them fell over the edge into euphoric bliss together.
Tender kisses trailed down Izuku’s spine as the two cooled down from their climax before Aizawa withdrew from him with a soft hiss. Fumbling for the nearby tissue box, Izuku pulled a few out and awkwardly tried to wipe himself clean. Aizawa took the tissues from his fingers and proceeded to gently wipe away whatever sweat and semen he could find, tutting in frustration when the tissue tore and stuck to Izuku’s skin.
“Might be best to just shower all of this off.” Aizawa sighed.
“Y-yeah… I think I will,” Izuku found himself blushing despite everything he’d already done with his former sensei that night.
What did this mean? Could things go back to normal after this? Do I really want them to? The sex was incredible. The best I’ve ever had, in fact. But it's a little weird to hook up with an old teacher, right? My friends would surely judge me for doing this… and for wanting to do it again… So I should end this before it gets messy. Or is it too late? Have I ruined everything by not stopping this when his hands started touching me at the club? Why was he at the club? Does he hook up with random strangers all the time? Or former students?!
“Izuku!” Aizawa cut through his spiralling thoughts with a firm hand on his knee, “Breathe.”
“S-sorry!” He squeaked out.
“Don’t apologise. I didn’t catch everything in that mumbling tangent just now but I’ll address what I can…” Aizawa’s hand moved from Izuku’s knee to his cheek, cupping it tenderly and rubbing his thumb across Izuku’s cheekbone in soothing motions, “Nothing has to change if you don’t want it to. Whatever you want is fine with me. If you want this to be a one-time thing, then I’ll never mention it again. If you want to ‘hook-up’ on a semi-regular basis, I can do that. If you want more… something closer to… ah… dating… then I’m open to that too.”
Izuku sat there in stunned silence as he absorbed Aizawa’s words. He wants more? His heart rate took off at the thought.
“What you decide to tell your friends is up to you. I can stay silent on the matter, if that is what you want. As far as why I was even there at that club in the first place…” Aizawa sighed heavily, “A mutual friend of ours tricked me into going before forcing me onto the dance floor with you. Clubs aren’t really my thing. I work two jobs and have Eri to look after. The free time I do have is either for her or sleep.”
“Oh.”
“Not that I didn’t enjoy our time on that dance floor… or what came after it…” Aizawa said with a smirk, making Izuku’s breath catch, “And I can handle a little mess if it means I get to spend more time with you.”
“I… I think I’d like that…” Izuku whispered, “I’m not sure if I’m ready for anything too serious just yet but I’m not gonna deny how much I liked what we did tonight.”
Aizawa’s posture relaxed a little and he smiled at Izuku with such warmth that the young hero couldn’t resist pulling the older man in for another kiss.
“Let’s go shower…” Aizawa’s voice was husky as he broke away from Izuku’s lips.
“One more question.” Izuku gripped the man’s arms so he couldn’t stand up just yet, “Who was this mutual friend you mentioned earlier?”
“A brat who's getting his ass kicked for using his quirk on me without permission.” Aizawa growled out.
It was a tone he and the rest of class A were very familiar with. Annoyed but not really pissed off.
“So it was Shinso?” Izuku guessed.
“Correct.”
“He brainwashed you into coming to the club?!” Izuku frowned at the thought of Aizawa being under his friend's mind control the whole time they were dirty dancing.
“No. He arranged for Togata to babysit so he could ‘have a night out with his mentor’ and took me to that club of all places. I was worried he was confessing at first. But then I saw you, alone on the dance floor and I knew…”
“Shinso planned this?” Izuku was baffled. Was this why his friend was a no-show? Technically he did show up but he never made his presence known to Izuku. Hell of a way to try and cheer up your friend.
“I was just going to leave you be. I didn’t want to come across as creepy, grinding up on my former student... or take advantage of you when you were drunk… but when I went to leave, Shinso caught me with his quirk and forced me to go dance with you. As soon as I was behind you, with my arm around your waist, he released his hold on me. I can’t blame him for anything else I did after that.” Aizawa looked a little sheepish and worried that Izuku would be angry at him.
“It’s okay,” Izuku said sincerely, reassuring Aizawa with a smile, “Really. I might give Shinso hell for his methods… but… I’m not sorry this happened.”
“Me either.” Aizawa kissed him again and Izuku found himself back in that warm, fuzzy headspace where nothing else mattered but the feeling of soft lips on his.
The couple continued kissing all the way through their shower and for the rest of the night… and morning after. As they sat in quiet contentment, eating their breakfast next to each other on the floor in front of the couch, Izuku realised how comfortable he was. Being with Aizawa was easy. Almost as natural as breathing. He didn’t feel like he had to walk on egg-shells around him. He felt more seen… and loved… than he ever had with Bakugo.
In one night, everything changed once again.
But instead of destroying Izuku’s world, this time, Aizawa rebuilt it.
A few days later, as Izuku sat down to eat dinner with Shota and Eri, his phone buzzed from a new message. Shinso had sent him a photo. It was dark and blurry, making it difficult to understand what he was staring at until it dawned on him. It was a photo of him dancing with Shota at the club! Thankfully it was terrible quality so no one would be able to see what they were doing while dancing but it made Izuku blush all the same.
His reaction had Shota raise an eyebrow at him curiously so Izuku showed him his phone. Shota let out a small indignant huff as he took in the image before eating again, a tiny smile blooming on his tired face.
“Still torn between killing him and thanking him.” Shota said between bites.
“Who do you want to kill, Daddy?” Eri looked worried.
“Just a brat, sweetheart.”
“Don’t worry, Eri. He doesn’t mean it.” Izuku reassured her.
Another message buzzed through on his phone, asking if Izuku was ‘all cheered up’. Feeling light hearted and spontaneous, Izuku lifted up his phone and told everyone to smile for a selfie, sending it off to Shinso as his reply. His friend was swift to respond. Not with shock but a smiling emoji and ‘about fucking time the old man was honest with you’. Izuku chuckled quietly to himself at that before sending one last message to Shinso for the night.
‘Thank you. For everything.’
