The beach was messy. Very, very messy. And you were the monster that was coming back from it with tar on your shins and sand in almost every crevice

Kaminari pounded on the bathroom door in annoyance. You had been in there for 30 minutes and he was starting to get impatient.

“Hurry uuhhhhhp,” he whined. “You’ve been in there for five-ever.” Kaminari leaned his back on the door, making the lock shudder and door thump.

“I told you I was gonna take a while, Kam.” You responded halfheartedly, while massaging the shampoo into your scalp. The water hitting the floor felt quiet for a moment.

“I didn’t think you’d take this long.” He continued complaining through the bathroom door. “Oh, and just letting you know, Ser and Kyoka got SO bored waiting, they went to grab food from downstairs lobby.” Your fingers stoped moving. You thought you’d heard the room door open and close earlier.

“I mean if you’re that desperate to shower, we could always share.” You wondered if he could hear the excitement in your voice, but after a few seconds of silence on his end you wondered if he heard you at all. “Denki? Door’s unlocked, and Hanta and Jirou are downstairs, probably getting high or something if they’ve been gone for this long, and knowing them they-” but your long list of reasons was cut off by the shower curtain being pulled back by a hand you knew a little too well.

Kaminari exhaled deeply while he took in your figure. It wasn’t often he saw this, at least from you, he desperately wanted to remember every inch but you were quick to grab his wrist and edge his body in further. He fumbled forward but eventually found his balance in the shower. Now the experience became completely immersive. Your lips were pursed in a crooked grin before you handed Kaminari a soapy loofah and turned around. “I was wondering if you could scrub my back. There’s a spot I can never reach.” The words slipped off your tongue so easily and so carelessly. It’s like you had rehearsed this. Kaminari was certain his cheeks were glowing scarlet at this point. Your hand scooped your hair and brought it over your shoulder to give him full access to your spine and others. You swear you heard him gulp.

Sure, you two had been somewhat intimate, but this was intimate. The kind that you had never shared before, the kind you thought you weren’t supposed to share.

The loofah scrubbed at your skin with Kaminari’s fingers seasoning the feeling. This was only the second time you’d ever felt such a focused presence like this emit from him. (The first time was when you watched him try to tune his guitar by ear.) Your awareness kicked back in once you realized the motion of his hand had slowed to a stop and pulled away.

Turning over your shoulder to give him a shit-eating smile he would deny that he loved, you certainly didn’t expect to be practically nose-to-nose with him and his water-freckled face. Your eyes shot open and he peered into you, now taking in the proximity of your bodies. You were both compromised, and that was all it took. His pupils blew up like fireworks at the sight of you this close and you could tell in his shifts in positions that he was itching for something. Maybe it was a touch or a sign–you weren’t completely sure–but you placed your hand over his. You guided his right hand to the spot just above your hip that you knew he was used to resting in. Your eyes never left his, and his hands eventually realized their true spot on your love handles, holding to your sides, saying “I’ve got you,” in the only way he could say at that moment.

It wasn’t long before the rest of him melted into you. As quickly as you inhaled from the contact, Kaminari exhaled hotly into the junction between your neck shoulder before leaving a tender kiss on the protruding muscle cause by your turned head. You couldn’t help but giddily smile and bite your lip to yourself, hoping he couldn’t see your excitement. He continued leaving kisses along you neck and collarbone until you turned to face him, forcing Kaminari to pull back, but his hands still clung to your sides. You could tell he was drunk on you and couldn’t help but hold your grin. Kaminari chuckled and crouched over so his forehead tapped yours.

Your fingers traced his lips that dared to press into yours. “Today was perfect,” you let out.

“What is it, baby?” he asked, a smile pulling on his lips. Your giddiness was starting to infect him.

“Just thinking about how perfect today was for us, like specifically us.”

“For us?”

“Yup. For you and me,” you unnecessarily clarified. His hands ran up your sides while he eyed your body under his touch. You grabbed his face, though, and forced his eyes to you. “Us, okay?”

And in the most sincerest way possible, he smiled at you, content with the pronoun used to describe you two. The shower felt impossibly warmer as the steam was starting to come into play, fogging up any actions that followed. Of course you’d blame them on the steam and he’d blame it on those damn eyes that were impossible to say no to. You were both painfully in denial and dancing with devils.

It wasn’t long before he had your back pressed into the damp tile walls, his lips ravaging yours. Your hands grasped on his blond locks like you would fall without his soft hair between your fingers. It’s not like he was any better though, his fingers pressing into your love handles, holding for dear life. You were both so scared the other would slip between your fingers if you didn’t hold on tight enough. You were both blind to see how dependent you were on each other. Being friends for so long does that to people.

The primal kissing eventually slowed down, allowing oxygen to reach your brain. Your slowly trailed one hand down from Kaminari’s hair, exploring his shoulder to his forearm before finding his half-erect dick. You fingers delicately glided up the underside of his shaft (this was your way of letting Kaminari know he was about to have the best handjob of his life), before you started pumping up and down, your thumb occasionally swiping over his tip.

You knew exactly what Kaminari was feeling at the moment it happened. The way his shoulders would flinch whenever he repressed a god-awful, bottom-like moan to avoid your teasing. The way his lips became tender and sensual on yours as he tried to exhibit some form of self-control. The soft groans and pursing eyebrows you never missed from him. Kaminari came up for air. You knew he was close by the way he hid in face in the junction of your neck and shoulder and the sweet little chokes and moans he couldn’t keep bottled up anymore.

Your hand worked faster, up and down, bringing Kaminari to his high that was so close, so so close. He was ready to beg for it when he felt your hand abruptly pull away, but the reason for it became known.

“Babe? Are you still in there?” Sero volumed into the door.

Shit.

It should have come to no surprise that your boyfriend had been gone for long enough to expect his arrival at any given moment, but in your dreamy state with Kaminari, it seemed that both of you had lost track of time. You both had become unaware of the the unnerving beep of a hotel key sensor that would have yanked anyone back to the ground zero of reality.

Kaminari’s eyes widened at his voice. That pit of guilt he always tried to ignore built in his stomach. You should’ve been more cautious. You should have recognized the lazy steps of Sero Hanta come in.

“Babe?” He repeated. Kaminari pitifully tried to pull away, but you were quick to make your palm and grip the only thing he should care about again.

“U-uh, ya. ‘M not done yet, though,” you responded over the water’s rhythm. Sero shrugged it off, mumbling something about how you’re weird for taking such long showers.

Your hand was starting to find it’s pace again, stroking Kaminari up and down and up and down. You bit your lip, trying to desperately forget the world outside.

“What are you...-fUck!” Kaminari gasped, trying to think rationally about the situation you were putting him in.

“You really thought I was gonna let you off that easy?” You words would smirk if they could. “Just keep quiet. Everything’s gonna be fine,” you whisper into his ear. Despite the steaming water, he shivers from a multitude of things. Your voice, your touch, the absolutely horrifying fact that your boyfriend was waiting for you just outside this bathroom door and yet you were so adamant on helping Kaminari get off with your hand. You were practically a monster.

He absolutely loved it.

It was that extra squeeze you added just for him that sent him into a pleasure-filled spiral. His hips pitifully fucked into your grip a few times and his hands squeezed you with such a raw grasp, it took everything in you to not tease him about it. His whimpers and moans vibrated to your collarbone and eventually, his small thrusts came to a stop and it seemed that he remembered how to breath again. It was shaky, but breathing nonetheless. A soft and stuttered fuck instinctively rolled from his lips before he lazily lifted his head from your shoulder. Kaminari’s hair was now shaggy and damp, casting over his ore eyes. He looked down and noticed the cummy mess all over your hand and stomach. He could only smirk before meeting your confident eyes.

“Y’know, I would offer to clean it all up for you, but uh, your boyfriend has us on a bit of a time crunch so you’ll just have to settle for the hand,” Kaminari snarked before grabbing your wrist and bringing your white-covered hand to his face. He tried his best to keep eye contact with you while lapping all his cum from your fingers and between. You were amazed at how he was somehow cocky as ever, though he was probably just annoyed that despite any common sense, you “forced” him to pathetically cum all over you.

You had almost gotten lost watching him clean himself from your palms, but his soft and swollen lips finding yours again crashed a wave of reality into you again. Your melted into this one, tasting the lingering saltiness of his seed until the taste vanished and all that was left was him. Well, almost all that was left. You sighed when he pulled away, your head now averted in shame.

You needed and escape plan and fast.

It took a minute of contemplation, but eventually your were slipping out the bathroom, the water now turned off and steam seeping out door by your sides as is you were an angel, at least, that’s how Sero saw it when he noticed you finally coming out of your cave.

His head had perked up from his mindless scrolling to notice you. His view followed you all the way to your bag of clothes. You rummaged in it for a bit before turning around and meeting Sero’s gaze. You smirked at him. “What?” You knew exactly what you were doing.

“Nothing, you just...” Sero’s hue changed a bit while he tried to find words. Like a fox, you approached the prey that was you boyfriend.

“ ’I just...’ what?” You mocked him and you swear his cheeks turned every color of the rainbow just from the sound of your voice. Sero gulped as he resisted the urge to look you up and down like you were his last meal. You bit your lip before straddling yourself on top of him. This was too easy.

You licked your lips while your hands glided down from his stomach to the rim of his pants. So much tension and no semblance of a conversation. It was like you could read each others minds. Your fingers started tugging his pants down while he watched in anticipation. Neither of you had even noticed Kaminari slip out the bathroom and to the entrance door.

Then the heavy protective door fell shut. The click of the latch caused Sero to whip his head to the entrance of the room to see Kaminari fully clothed, accompanied by damp hair and a towel over his neck.

“S-shit,” Sero cussed. He shoved your hands away from his shaft and adjusted his pants. This was the moment you realized Kaminari's secret talent of acting. There was not a single care on his face until he saw the two of you. His hand’s gripped the towel that was around his shoulders while he shot the both of you a confused and then almost disgusted look upon realization.

“Were you guys about to- on MY bed!?” His tone perfectly reflected that sort of morbid disgust one would feel when catching their best friends trying to fuck. You weren’t sure how he pulled it off.

Sero sat up and cleared his throat before you slid off him and went back to your bag, looking for clothes.

“Were were you,” Sero managed to choke out, trying to relieve the awkward aroma he was imagining, though he did find it a bit unsettling how okay you seemed with Kaminari seeing you with nothing but a thing hotel towel to keep you decent.

“Got bored of waiting,” Kaminari shrugged before pulling his towel off his shoulders and setting it on a table. “I ended up just showering in Bakugo’s room since the dude takes showers like a bullet. I think he might actually qualify to be in the Guinness Book of World Records or something, it’s actually insane.” Sero just smiled at the useless knowledge Kaminari had bestowed on him, knowing how much he could ramble on about anything and nothing.

Like it was a character cue, that stupid, sullen, keycard click for the hotel door clicked and in came a new opponent.

As quickly as Jirou came in, you had retreated back into the bathroom where you changed into some clothes. You may have also sought sanctuary in there to avoid Jirou’s habit, since you knew the first thing she would do after entering the room was plant a soft kiss on Kaminari’s cheek. It was only logical that she show affection to her partner. They would have it no other way, of course. It was a habit between them that you knew too well, perhaps it was even a habit that had driven you to even consider dating Sero.

It was only about a minute before you came out of the bathroom this time, though Jirou’s perfect face was the first one you saw upon exiting, most likely because she was aching to finally shower and rid herself of the tides messy short-comings. You flashed her a friendly smile before saying “it’s all yours” and walking past her to get to Sero who was still laying on the bed. You tapped his lovelessly knee to grab his attention.

“We’re going for dinner soon so you should probably shower in Bakugo and Kiri’s room,” you suggested. He could feel the shallowness in your suggestion, but obeyed regardless since he knew Ashido would have his head if he was late to her dinner reservation. Sero ruffled the top of your head before grabbing his change off clothes and dragging his feet to their friends’ room.

Finally, the click of that latch felt appealing. You exalted and flopped onto the mattress. The screaming of the distantly running shower drowned out your mind. “Okay,” Kaminari shoved your body over a bit. “Scoot over. You’re not the only shitty human being here.” He plopped down next to you, exhaustion consuming his entire being. You were curious how no one had noticed his flushed post-sex glow. “Hm?” He could tell something was on your mind when your staring didn’t falter.

You sighed and said the most painful thing you could’ve. It was now that your staring would falter, now taking interest in the ceiling.

“I think love you.”

Kaminari blew air. It was a lot to say and a lot to hear, but it only took him a moment to process.

“I... think I love you too,” he cringed a bit. You could tell. Not because there was anything wrong with loving you, but because he really shouldn’t love you.

You thought you were gonna vomit. You were both sick.

“This is so fucked.”

Bathing yourself was pointless. You were still dirty after showering. That tar was forever stuck to your legs.

The beach was messy.
