Chapter Text

There was a legend on Midoriya's university campus; if you pissed in the fountain at midnight, you'd summon a mermaid. It was ridiculous, he agreed. Probably some rumor created by drunken students stumbling about and engaging in public urination. And yet, there he stood, on the fountain ledge, in the middle of the night, with his dick out.

The fountain before him bubbled lightly as water trickled from the statue in the center. Around him, the quad was silent, not a student in sight. Normally it was crowded and bustling, but at midnight, people were either down town drinking, studying with friends, or in bed.

What was he doing there? He didn't believe in myths, and even if he did, would they be interested in him in return? With a sigh, he considered the growing need in his bladder, and decided, what the hell. He let it go, pissing into the clear water of the fountain, watching it turn cloudy. He'd held it in all afternoon, embarrassingly wanting to make sure he had what he needed to summon the creature. But as he finished, and put himself away, he stared at the pool that he'd desecrated, and watched as nothing happened.

How stupid he felt right then.

He was about to step down and walk back to his apartment, shame weighing down on him, when something wrapped around his ankle and yanked. With a cry, he slipped forward and came down with a splash, blinded by the spray of water. After rubbing his eyes, he opened them again, and almost let out a second scream. Right before him, was the most beautiful man he'd ever seen in his life.

There were blood red eyes staring at him, piercing straight through him. That face was handsome, gorgeous even, like chiseled marble. And it glared at him from above it's muscular body, and lower than that, his eyes fell, and his jaw dropped. A large tail in place of legs, with thin, translucent fins, and shimmering red scales glittered beneath the surface of the water, the same color as those striking eyes, which he whipped his head up to meet again.

"You're real!"

"Hah?" The creature seemed less than inclined to engage him in conversation, and he gulped. He'd summoned the mermaid - merman - and immediately pissed him off. "The fuck is wrong with you?"

"Wha- I-"

"You just think you can piss in my home and get away with it?"

"Oh." In hindsight, he should've realized that a legendary creature would not take well to being peed on. Perhaps he shouldn't have held it for so long after all...

"What kind of fucking dumbass goes around pissing in fountains?! Bunch of idiots on this fucking campus. Do you even fucking know what I put up with every damn night?" Midoriya began to shrink back against the curve of that fountain wall as the merman ranted at him. "For college kids, you're all fucking stupid as shit. What, do you think pissing in my fountain would grant you a dumb wish or something?"

Beneath the anger of that glare, Midoriya could only gulp, and meekly answer, "Yes..."

The creature stared at him, unblinking for a second, before screaming his rage to the sky. "Dumbass shitty university! Teach your students common sense! Fuck this place!"

"I-I'm sorry," Midoriya tried to say, before those red eyes flashed on him again.

"Are you?" The sudden calm of the voice caught him off guard, and all he could do was nod. "Alright. Good." A maniacal grin came over the mythical being's face, and he grabbed Midoriya's arm with a steel grip around his wrist. "You're going to make it up to me then."

Blinking in surprise, Midoriya nodded again, obediantly. "Okay," he agreed. Anything you say, Mr. Merman.

"Take your shitty pants off." Hm?

"Hm?"

"You heard me!" The merman barked, pulling away to give him the space he needed. "Take your fucking pants off!"

"O-Okay!" Midoriya blushed as he removed his pants, then continued to remove his underwear as the merman waited, watching him expectantly while he draped his soaking clothes on the ledge beside himself. He sat there in his shame, completely flustered as he had no idea how he'd gotten here. One second, he was trying a stupid, immature college challenge, the next, he was half naked in the fountain with a merman.

"Right," that gruff voice grunted, pulling himself forward to lean over him. If Midoriya wasn't already flaming red, he would've flushed some more. The merman really was super pretty. And he was so close to him; he could see his blonde eyelashes, and the golden flecks in his irises.

Outside of the fountain, he noticed the rest of the quad seemed veiled by a shimmery curtain. Even if people were around, he had a feeling they would be protected from sight by some kind of magic.

And before him then, the merman's hand reached toward him, and he caught his breath when it hovered over his groin. It was slightly disappointing to see it stop above him, waving in the water, but it would be even more foolish for him to have expected that his repayment to the merman would involve receiving a hand job from said creature.

It started slowly, the water swirling around his cock, the previous cloudiness now surrounding his pelvis. He could tell that something magical was happening, and he watched in awe, when suddenly, he felt something shoot up his urethra, and he froze in shock.

"Ah-!" He couldn't even gasp, his chest was tight. The singular sensation of his piss rushing back up his dick struck him, and his whole body tensed. Midoriya's jaw clenched as the now cooled liquid shocked his cock, quickly gathering once again in his abdomen.

All he could do was shiver at the sensation of his bladder stretching, becoming burdened once again, his body undergoing a trauma he'd never thought he could experience. It was all he could do to breathe, his eyes locked on that smirking face as it used its power over water to force the piss back inside of his body. He shuddered, his eyes rolling up as he realized just how much he'd peed before. He might have even moaned a little.

When it finally stopped, he gasped, his eyes opening wide, and he shivered beneath that mythical body. The water around him was clear, and the merman seemed smug as it had taken in all of his reactions. Midoriya couldn't help but study the way it's tail lay, draped across the bottom of the fountain, that body held up by the strength of its arms.

"Now," the merman purred, his voice a low rumble. "Time for your punishment."

"H...Huh?" Midoriya asked, breathless. "That wasn't it?"

"Ha!" The merman barked out, and he flinched. "That was just you taking your fucking piss back. Now," he said, both his hands gripping the ledge on either side of him, his strong, barrel arms caging Midoriya's thinner, human body. "I get to show you what's it's like."

Midoriya gulped, feeling his body tremble beneath that intense gaze. But it wasn't from fear. He was grateful the other was staring at his face, and didn't notice his hardening desire.

"Okay..." He said, before strengthening his resolve. "Okay. But only if you promise to grant my wish." His voice was weaker than he wanted, but his words stalled the other being momentarily.

"Hah?"

Before he could lose his bravery, he asked a second question; "And tell me; what's your name?"

"My name?" The merman growled, still clearly stuck on his first statement. The human nodded, trying to keep his face as innocent as possible. After a second of Midoriya wondering if he would respond or not, the merman said, "Bakugou Katsuki."

"Bakugou Katsuki..." Midoriya murmured, feeling the name on his lips. What a beautiful creature. How he wanted to run his hand over that shimmering tail, feel the flutter of those tender fins. "I'll take your punishment, but please grant my wish."

Bakugou scowled at him, but he didn't outright say no.

"We'll see," the merman grumbled. Well, it was the best Midoriya could ask for. He braced himself, and gave himself over to the legendary creature. Recognizing that he was ready, the merman reached forward and gripped his hips. "I'm going to show you what it's like to be fucking pissed in."

Maybe it was because those strong hands were on his bare hips, distracting him, but it took him a couple seconds to realize what the other was getting at.

"Oh," he said, again. "I see." His voice was small, his body shrinking in on itself. Was this all worth it? Before, he hadn't even thought he'd get to meet a mermaid, but now, well, anything seemed possible. "Okay. Okay," he repeated with more certainty.

Something flickered behind those eyes, and he tried to study them. He couldn't tell, but he thought he saw an ulterior motive somewhere, in those pools of red.

Bakugou didn't speak as he reached between Midoriya's cheeks and pressed inside of him, pulling a moan from the human's throat. He gasped, surprised at how quickly the merman was taking this, how pleasurable he was making it. A second finger joined the first, the two digits twisting inside of him, spreading, dragging moan after moan from him, before pulling out with a ragged gasp from Midoriya.

But that wasn't the end of it. The merman's hand then slid over the front of his tail, where his pelvis lay, and slipped into a slit that was easily camouflaged by his scales. He pulled his cock out, and Midoriya tried not to let his lust show. It wasn't human by any means; it was smooth and slick, with no head, tapered at the end. But it certainly was thick, and already hard.

He tried not to watch it approaching his ass, his eyes fluttering close when he felt that pressure in his entrance. It was embarrassing how much he moaned in front of this hot merman, but he couldn't help it; he was a slut.

When it began to grow inside of him, his legs spread around that tail, Midoriya was distracted from his own pleasure when he felt Bakugou's stuttering breath. Opening his eyes, he watched, enamored, at those gaping lips, those eyelids half lowered. He wondered if he felt good to that merman, if his fishy cock had ever been taken by a human before.

Bakugou was fully inside of him, and the both of them were breathing hard against each other, their eyes half-lidded. As they sat there, Midoriya on that cock, the human almost forgot for a moment what their purpose was in the first place.

Then, the merman came back to himself, regaining his mental fortitude, the fog clearing from his eyes.

"Alright," he murmured, with effort, looking as if he were bracing himself. Midoriya watched him curiously, wondering, for a moment, what was going on in his mind. Then, his eyes widened, and he gasped.

He could feel it inside of him, the merman pissing. It was strange, but then again, this whole situation was strange. Midoriya's eyes locked on Bakugou's, and he felt like time stopped for a moment. Bakugou's gaze was holding on him as well, so close they were breathing in the same air. Maybe it was just him, but he almost thought he could sense the other's heartbeat.

The merman finished, and released his breath. Midoriya knew that look on his face, had watched as those eyes struggled not to roll up in bliss; it was an expression of relief. He bit his bottom lip, trying not to think of his own full bladder, aching once more, though the sting that still lingered in his cock made him tender, and reluctant to relieve it again.

"Hah...Take... Take that..." Bakugou said, and Midoriya wondered at the breathlessness of the merman. His eyes were drenched in what could only be described as desire, becoming an open window to his soul, as they say. The human nodded, letting the other feel like they'd punished him for his crime. "Now," Bakugou rasped, mentally gathering himself again. "What was your stupid wish?"

Midoriya looked up at him, his eyes peering into those red irises, trailing over those lips, and he said, "I want you to fuck me."

Bakugou stared at him, as if he couldn't believe him. Then he said, "That's really why you fucking pissed in my fountain? You wanted to get dicked down?"

Midoriya nodded, the blush returning to his cheeks. But it wasn't from embarrassment this time.

Bakugou stared at him for another moment. Then he gripped the human's hips, and pulled him close, Midoriya letting out a cry as his body slid forward, that merman positioned above him, and he kept himself just barely afloat with his elbows on the fountain ledge.

The merman's grin was savage, his teeth sharp, and he began to thrust into Midoriya, who let out gasps of ecstacy. The fountain splashed about them as their bodies writhed together, Bakugou humping him desperately, neither of them in the optimal position for fucking, with that giant tail in the way. But it was plenty for the horny human, who begged and moaned, crying in bliss as that fish cock speared into him, over and over and over again, that strong pelvis pounding his ass.

"Fuck, should've known you were a horny bastard," Bakugou gritted out as his humping created waves in that small fountain. "Your ass is too tight for you to not be."

Midoriya's head rolled back as euphoria brimmed beneath his skin. Fucking a merman was even better than he'd imagined. "Ka...Kacchan..." He breathed out, the nickname escaping him.

"Hah?" Bakugou grunted, slowing momentarily. "The fuck did you call me?"

"I... Oh," Midorya said, realizing that he'd said that out loud. "Um... Kacchan?" The merman glared at him then, but he didn't stop.

"You're lucky you're fucking cute," was all Bakugou said before closing his eyes and drilling Midoriya's ass, the human losing focus and whining as the pleasure rose within him. The merman thought he was cute, the merman thought he was cute, the merman thought he was cute.

Groans rolled from the human's throat as his angled his hips up for the merman. But despite the heat that was growing between them, it was difficult to ignore that desperate ache in his bladder. Midoriya tried to focus on the pleasure, but then Bakugou's hand came to rest on his stomach, and he could have sworn he felt the liquid inside of him swirling.

"Fuck-" Bakugou gasped against his face, straining from the effort of fucking him. Midoriya watched from beneath his eyelashes, seeing all restraint dissipate from the merman's expression. "Piss. Piss on me, just fucking do it."

Midoriya didn't want to hesitate; he was obedient, immediately trying to let himself go, but his erect cock was standing straight up, above the water, and he whimpered his struggle to the merman. With a growl, the mythical beast took control of the water inside of him, encouraging it out, and Midoriya gasped. Suddenly, he was pissing against the body that hovered over him, and Bakugou's head tilted back to let out a moan.

Watching that face as it lavished in his piss, Midoriya couldn't help but wonder if having his fountain pissed in every other night for years hadn't done something to the psyche of this mythical creature. How lonely this merman must be, confined to this fountain his whole life. How his desires must have warped and festered over the years, turning him into the horny young beast that he was, laying on top the human then.

Bakugou grabbed Midoriya's cock, and the human let his own head tilt back, the relief in his bladder spilling to the rest of his body. He could hear the sound of his piss splattering against the planes of Bakugou's abs, louder than the water that fell from the statue. Then, his cock was angled up, and suddenly his stream was aimed at his own face, Midoriya startled when he felt it in his mouth. His eyes opened and his head straightened up, before Bakugou's lips crashed against his own, that tongue licking desperately into his mouth, while he coated them both in his urine.

His bladder finally emptied, but Bakugou kept thrashing in that shallow water, humping his ass while they sloppily licked each other's mouths, their pleasures mounting.

It didn't take much longer after that before Bakugou came, and he didn't stop, his seed and piss spilling from Midoriya's ass as he rode out his pleasure. The relief still fresh in his lower abdomen, the human groaned, before gasping as he shot his own load against the merman's stomach. Bakugou only grunted as it stained his skin, his thrusting slowing as the pleasure began to wane. Then, finally, they were still, the waters around them settling, and they panted against each other, covered in and surrounded by their own fluids.

As the glaze of lust melted from his face, Midoriya swallowed, then studied the merman before him. He startled at the sight of the other's tail; the once scarlet scales were now yellow, shimmering beneath the water like gold coins. His eyes rose up to see the still lust drenched face of the merman fixated on him, the golden flecks now blooming into a starburst around his pupils. Holy shit...

"Got what you fucking wanted?" That rough voice rasped from Bakugou's throat, this creature now seeming so sensitive and raw as he bared himself in the aftermath of their fuck. He looked legendary to Midoriya, like a god sitting in his own glory.

Rather than answer with words, Midoriya brought his hand up, gently reaching out to lay it upon the other's cheek. He watched those golden eyes slide close as he leaned forward and kissed the merman, sweeter than they had before, their mouths parting slowly to delicately taste each other's tongue.

As Bakugou's arms wrapped around his torso to hold him close, he felt a silent promise in that kiss, words unspoken, but understood nevertheless. Midoriya could come back anytime he wanted; just make sure to bring a full bladder.

Midoriya looked around at the empty campus, dark, as the closest light was that of the street lamps. In the middle, by the fountain, there was no light at all, just the gentle trickling of the small statue that fed its little pool. The sound pricked Midoriya's ears, like a siren song to him. With one last look to make sure he was truly alone, the human slipped out of his clothes and folded them, leaving them beside the fountain wall.

It was a little after ten at night when he stepped into the pool, sitting down, naked, and felt the magic veil ripple around him. Then he gasped.

Bakugou was before him, that devilish smirk leering in his face. There were immediately hands on his legs, running over his bare skin, encouraging his thighs to spread and allow that tail between them.

"You're late," he growled, his fingers digging into the meat of Midoriya's thighs.

"Sorry," he mumbled, still finding himself trembling beneath that intense gaze. Even though the creature was watching him with nothing but desire, Midoriya couldn't lose the awe he had for this merman. "I saw a group of friends walking around, so I did another lap before coming back."

"Tch," the merman scoffed, rolling his eyes. Studying those irises, Midoriya could see the tiny flecks of gold, so pale in that moment, they were easy to miss. "Just tell them to fuck off."

"I don't think that would work..." Midoriya said, before gasping as a determined hand wrapped around his cock. He wasn't hard yet, but that wouldn't last for long. Finding his chest tight, Midoriya looked back up to see a coy smile on that face.

"Stop blabbering, I wanna fuck you."

That was enough to get the human to shut up. Eagerly, he settled back against the curve of the fountain wall, watching the merman drag himself on top of Midoriya. He let his hands rest on those thick biceps, feeling the strength beneath his palms. As Bakugou got closer to him, he couldn't help but notice how red he was that night, his eyes, and his tail.

Midoriya gulped.

"Do you..." he started, halting the other. "Do you want me to...?" He didn't finish, just looked up into those eyes with his question on his face, knowing the other would understand what he meant. Bakugou set his hand on Midoriya's lower abdomen, studying his bare torso, then he smirked.

"Not yet." Then he lowered down the rest of the way and captured Midoriya's mouth, parting his lips to allow himself access. The human sucked on that tongue, caressing it with his own as it explored his mouth. He whimpered a little, pressing his hips forward against that tail. He ached for relief, but Bakugou was going to take this slow tonight.

The merman's hand released his cock and crept back, between his legs, snaking further down, until he was pressing inside of Midoriya, dragging a moan from him. With that finger inside of him, the human couldn't help but pant on that tongue. He'd found his mythical partner to be exceptional with his hands, particularly with his fingers. A second one entered him, and he was whining, feeling himself stretched and rubbed, panting like a dog when that hand finally pulled out.

When Bakugou pulled away, he had a self satisfied look on his face, seeing Midoriya's eyes simmering with lust, saliva trailing down his chin.

"Flip over."

He obeyed, turning onto his knees and resting his elbows on the ledge. Unable to see his partner behind him, he could only hear when he brought out his cock from the sound of his hand slipping up and down it, faster, and faster, and faster.

Midoriya had learned much about his mythical partner in the times that he'd visited him. There wasn't much talking during these visits, so the information came to him in short bursts. He found out that Bakugou was tied to this fountain, created along with the pool of water's inception. He'd also learned that he could enter between the veil at any time of day - he'd found this out after the horny young beast had pulled him in as he passed by on his way to class, making him very late.

The most interesting thing he'd learned, in his opinion, was that Bakugou's scales changed color based on the water that he absorbed. Living in that clear pool, his normal hue was scarlet red, but whenever Midoriya pissed on him, they would turn gold, and he looked like a man covered in auric treasures. Even the center of his eyes would become a brilliant, golden sun.

Midoriya was dragged from his ruminations when he felt that presence entering his hole, his eyes widening as it began to fill him with it's width. Taking it raw like that, Midoriya clenched his jaw; he could feel every inch. He hadn't brought any lube, but then again, he never did; he liked it rough.

By the time that coarse pelvis was pressed against his ass, Midoriya was shivering. Bakugou's chest rested against his back, his arms hugging Midoriya's waist, squeezing him tight, making him wince. The merman knew how much he was holding in, forbade him from releasing it, yet still he pressed on his stomach.

After soaking in his heat, Bakugou breathed deeply, through his nose, then began to pull out. Midoriya gasped, then moaned low, feeling that cock drag roughly through him. Then, Bakugou shoved himself back in, Midoriya crying out. The merman started fucking him, just as he'd promised, humping his ass while Midoriya's knees braced against the bottom of the fountain.

Around them, the water splashed, crashing against the walls, churning with their thrusting. Midoriya was beyond grateful no one could see them, and hoped the veil closed off their sound too, because he was noisy when he was getting pounded in the ass.

"Ah! Hah, Kacchan, hah!" Midoriya moaned that nickname, feeling those arms tighten around him as it left his lips. Those sharp mermaid teeth began to nibble on his ear, the human gasping as that cock speared deep inside of him. There must be something wrong with him, he thought, to be this horny day after day, craving this pleasure, this merman cock, and never tiring of it.

Midoriya began to shift his hips, whimpering despite the pleasure. The ache in his groin couldn't be denied, not when it was starting to interrupt his enjoyment of the moment.

Thankfully, he felt the merman reach down, his hand wrapping around his cock. He whimpered, feeling it angled down, between his legs, pointing toward his partner's tail.

"Do it," Bakugou rasped in his ear, grunting with his thrusting. "Piss already."

With a groan, Midoriya began to pee, the relief immediately spreading through his body. God it felt so good...

Behind him, he could hear Bakugou's little whimpers, the merman unaware of how his desire showed. But apparently he decided it wasn't enough; as he relieved himself, Midoriya felt the fountain water beginning to lower, and then he gasped as he looked around. The merman was using his power to pull the pool back, and dam it with his magic against the other side. Looking down then, between his own legs, the human watched his own piss stream aimed at that beautiful tail. He watched in awe as it slowly turned orange, then yellow, before his very eyes.

"Fuck," Bakugou gritted out, his breath warm against the back of Midoriya's neck. "Fuck fuck fuck. Fuck." 

Midoriya was well aware of how it made his partner feel, soaking in his piss. He heaved as the relief filled his body, and he was so relaxed as that cock continued to slide through him, that scaly pelvis slamming against his ass. Bakugou thumbed over his slit, his piss fanning and splattering against his own thighs.

When he finished peeing, Bakugou released the water with a gasp, and it flowed back, filling the space around them again. They moaned and rocked together, the pleasure rolling through Midoriya unrestrained now. It rose up, and up, until he was whining, and begging, and-

"Ah!" Midoriya released his passions into the water, his body trembing around the merman's cock. He could hear those teeth grit before Bakugou came too, fucking it into his ass before slowing to a stop. The human felt weak then, his arms shaking as he held up both his and the merman's bodies. After resting a moment, breathing deeply against Midoriya's back, the merman pulled out and laid against the fountain wall beside the human.

Midoriya's body collapsed against him, and he sighed. They breathed heavily together, regaining their strength. In their peaceful silence, Midoriya wondered if he should feel gross, all sweaty, covered in his own piss, with cum still leaking between his legs. But he felt great, blissful even, with that muscular body against him. Tentatively, he let his hand reach down and run over those scales, mesmerized by their golden shimmer.

He could feel those eyes watching his hand; he glanced up to get a glimpse of those irises, and saw stars there. Then, he felt his wrist grabbed, and he watched the merman bring it up to his mouth, pressing Midoriya's fingertips against his lips, before taking them into his mouth. He sucked on the human's index and middle fingers, his eyes narrowing as they held Midoriya's gaze.

He let the other lean in, releasing his hand to kiss him. Heat began to bloom in his chest; it wasn't like the heat of desire, this was warm, and tingly. His hand rose up to touch that cheek, melting beneath the soft strokes of the merman's tongue.

When they pulled away for a moment, Midoriya found himself lost in that golden-red stare. And then the words tumbled from his mouth.

"Kacchan, are you ever lonely?"

He watched those eyes blink at him, confusion turning to distrust.

"Hah?" He pulled further away, the space between them growing cold. "The fuck do you mean? Why would I be lonely? I'm surrounded by people, fucking idiots, every damn day."

"Right," Midoriya said sheepishly, trying to figure out how to fix this. "But you don't have anyone to, well... Talk to, or um, no one even knows you're here..." He felt himself withering beneath that glare, bracing himself for whatever Bakugou said next.

"You know I'm here," he finally said, too calmly. Midoriya held his gaze carefully.

"Do I make you less lonely?" Bakugou didn't answer him immediately. Instead he stared at the human's face, studying him cautiously.

Finally, he murmured, "Shut up," before leaning in against to kiss him.

There was more heat to this one, desperation growing between them. Midoriya allowed the conversation to melt away, allowed Bakugou to grasp his body and pull the human on top of him. Once again, they found themselves gasping, and thrashing, the water splashing around them.

He was willing to let it go, to drop it, willing to let the merman fuck the thought from his mind. In fact, he was certain the merman was planning to do just that. Midoriya was sitting on that cock, and riding his mythical partner, bringing him closer and closer to climax when Bakugou gripped his shoulders and pulled his body up against his own.

"Deku," he rasped, with that absolutely vulgar voice of his. "Come back tomorrow night."

Midoriya blinked in surprise. "Sure," he said between his heaving breaths.

"And the next night."

"Okay."

Those fingers dug into his ass cheeks, causing him to wince in pleasure.

"I like you, idiot." Midoriya found himself gasping as he sat down on that cock.

"Really?" When Bakugou stared at him incredulously, sweat beading his brow as the human warmed his cock, Midoriya gave him a sheepish look. He returned to rising up and down, his thighs burning. "I like you too," he said, panting between words.

"Good," Bakugou murmured. And in that moment, Midoriya thought his magical partner looked almost like a normal, college student. An incredibly attractive and buff college student with golden eyes, but still.

The human tried to play it cool, but he could feel his giddiness rising up, knowing that the merman craved his presence. He fell back to his rhythm, bouncing on that cock until he felt fresh semen streaming down his legs, and he helped the other ride out his pleasure before releasing his own against his chest.

They were both worn out, physically, emotionally, sexually. When the human got up, he winced at the ache in his legs, before sitting down next to the merman. They were both silent as they regained their breath, Midoriya trying not to overreact when he felt those fingers sneaking over and interlacing with his own.

When he was ready, they said their goodbyes, Midoriya taking note of the way the gold glittered in those eyes before the veil disappeared, along with his merman, and suddenly he was just some random naked dude standing in the middle of a fountain for anyone to see.

Midoriya stepped out, his teeth chattering as the cold night air bit at his wet skin. Tossing his curls about, he proceeded to shake the water from his limbs. He'd have to walk home in damp clothes, but it was better than nothing.

Turning around to where he'd left said clothes, he froze. Where were his clothes? He'd left them right there.

Panicking, he began to scour the edge of the fountain, but found nothing. He quickly looked around, feeling even more naked then, and he covered himself with his hands. Who the hell stole his clothes? Had he been too distracted by the merman's cock that he hadn't noticed some rascals from the outside world wandering too close and catching sight of his folded up bundle, and taking it for themselves?

Midoriya looked toward the path he had to take home, thinking about the fifteen minute walk to his apartment. Checking his watch, he saw it was eleven. He looked back at the fountain, and cursed to himself. There was nothing Bakugou would be able to do about it.

He looked back down the street that led to his home. It was empty, but well lit, and daunting. This was going to be one awkward walk home.

Chapter Text

"Can you show me how you do it?"

Midoriya was straddling Bakugou's tail, it's scales still orange from the night before. Looking into those eyes that held on him with suspicion, he saw streaks of gold. It was late, and dark, the veil maintaining their secrecy.

"Can't figure it out your fucking self?" Bakugou growled, leaning back against the fountain wall.

"I just want to do it right," he murmured in response, his hands tracing over those hips in front of him. He could hear those fins splashing behind him, a sign of the merman's irritation.

Midoriya had finally gotten Bakugou to open up enough to let him pleasure him. He watched those eyes flicker down to their own pelvis, to the slit that hid his cock. After having visited this fountain regularly for the past several weeks, Midoriya now found it easy to spot. In fact, he even noticed the slight bulge beneath, when Bakugou's cock was hard before he even took it out.

The merman glared at him, as if he was thinking up a retort, but he said nothing. Instead, he took a steady breath, before his hand moved to his hidden pouch. Midoriya watched, his breath short and his chest tight, as those fingers tenderly stroked the seam, the air fluttering from Bakugou's lips. The human looked up to watch that face twitch at its own touch.

Those green eyes widened slightly as those two fingers dipped into the slit, those sharp fangs biting their lower lip. Bakugou's breathing became ragged as he began to rub his most sensitive spot. His head tilted back, and Midoriya couldn't take his eyes away from that face, breaking out into a sweat as his pleasure rose. 

Bakugou stopped, his lower lip trembling between his teeth. He pulled his fingers away, his chest swelling with each breath. Those eyes flicked up to his own, wary still, but then his hands slipped to the side, waiting for him.

Midoriya took a moment, looking down, seeing the edges of that slit, just slightly swollen now. His hand reached forward, and gently, he touched it. Immediately, he heard Bakugou grit his teeth, and Midoriya spared a glimpse at his clenched jaw. Then he returned his attention to the matter at hand, running his finger over the seam, feeling the flesh beneath the scales.

Beneath that slit, he knew the merman's cock lay hidden. He could feel those eyes on him, watching him, listened to how the creature struggled to control his breathing. With a burst of courage, Midoriya's finger slid in deeper, and he felt the merman shudder. He traced the inner lining of that pouch, feeling the warm, soft, sensitive flesh.

At this point, Bakugou lost control of his throat, and he gasped, before groaning. Midoriya took that as a sign to press deeper, feeling the tips of his fingers sinking into that slit. And then he felt it, Bakugou's cock. It was softly pulsing, hardening steadily. Already he could see the slight mound beneath that scaly skin.

He looked up then to watch Bakugou's face, his eyes half-lidded, and glazed with lust. His shoulders were tense, his hands tight fists. Midoriya's fingers slipped inside, and he stroked that cock, watching that face spasm. The human slowed, tentatively caressing the other, realizing just how sensitive he was there. He trailed a slow finger along that shaft, fully hard and trobbing in its pouch, begging to be released.

Midoriya was in awe as watched Bakugou fall apart beneath his touch; he almost had the merman whimpering just by caressing his slit. His four fingers were inside, Bakugou moaning as they burrowed in and found something he hadn't realized the merman had; balls. Or at least, they were sacks. But given their placement, Midoriya assumed that they stored his seed.

With his own gasp at this discovery, Midoriya cradled them, seeing that cock begin to bulge out of its slit. His own body was beginning to shiver from want, and for a split second, he allowed his desires to take control. He pulled his hand free, Bakugou groaning from the sensation, left panting as Midoriya studied his now wet hand. The human stepped forward on his knees, until he was hovering over the merman's pelvis.

He was naked, of course, his clothes safely stashed in a trash bag, within the confines of the veiled pool. And his cock was hard, leaking without needing touch. But he was ready for it.

Bakugou watched him, still panting, as he angled his hips down, and pressed his dick against that slit, feeling how the other shuddered. And he himself whined as he felt the lips of that seam swollen against him, parting around him as he pressed forward. But he didn't push inside, he went slow as he began to rub, sighing as he was finally able to actualize the desire he'd kept secret for weeks now.

The merman was a mess, his hands reaching forward to grip Midoriya's arms tight, digging into his skin. The human could only watch as his partner gasped desperately for air with each breath, heaving erratically as his pleasure overwhelmed him. Midoriya wasn't nearly close, but he knew the merman was on the brink. So he took his chance, and pressed his cock deeper in, feeling the slit widen around him, his shaft pressing against the other's, who's responding wail was raspy and broken.

Midoriya rutted into that merman's pouch as much he could, feeling his hard cock against his own, before the other's back arched, his body spasming in the water as the orgasm ripped through him. The human could feel the seed as it spilled from the seam, and Bakugou's body finally stilled. The creature beneath him panted hard, taking a few moments for his eyes to become unclouded, then look up into Midoriya's face.

He was in awe. He watched Bakugou breathing hard, his body exhausted from the pleasure it had just experienced. Barely even conscious of his own actions, Midoriya reached forward and touched that jaw, lightly trailing along it's edge. Slowly, he leaned forward and kissed those lips, tasting the hot breath his merman was still gasping.

As they kissed, Bakugou began to regain his strength, his hold on Midoriya tightening, until suddenly, he was flipping Midoriya over, and crawling down, into the water. The human watched, noticing how awkward it was for the merman, to exist in such a small pool of water. As the mythical being situated himself between his legs, Midoriya wondered if the other even knew what it was like to swim.

Bakugou ripped him from his thoughts as he took Midoriya's cock into his mouth and began to suck. Immediately Midoriya groaned, his fingers lacing through those flowing locks. There was something so hot about this merman giving him an underwater blowjob, he stared slack jawed at the image. 

He could see Bakugou's head bobbing beneath the surface of the pool, could feel the suction and tongue around his shaft, the palm that held his balls. Midoriya winced when that tongue licked the slit of his dick, and moaned when it traced his veins.

That tail was curled up, over the water, against the statue in the middle, glimmering orange in the night. Midoriya swallowed, then settled back against the fountain wall. He closed his eyes, and did his best to relax; this had gotten easier the more often he'd done it.

Midoriya sighed, feeling relief fill his body. Gradually, gold began to seep through the merman's tail as he gulped, the color bleeding from his waist all the way to his fins, until finally, he was pure yellow again, and Midoriya was completely relaxed. His mermaid was always well fed.

Free of all physical sensations other than pleasure, Midoriya let his head roll back and allowed the waves of euphoria to wash over him. Those lips were so soft against his shaft, that tongue so luscious as it cradled him. He whimpered as Bakugou bobbed up and down beneath the water, bringing him closer and closer to the edge, until he cried out, feeling that throat grunt in reaction to his load.

He was spent, his limbs completely useless as he laid there, and Bakugou rose up on his arms, looking satisfied as he studied Midoriya. The merman dragged himself on top of the human, and immediately shoved his tongue in his mouth, Midoriya tasting himself there as he returned the gesture. There was a hand on his ass cheek, and it felt good; he felt lazy, and good.

How vast the difference was between the mermaid he'd first imagined, and the merman he made out with in that moment. There were times when he still felt awe to see that shimmering tail, those golden eyes. But as his hands traveled up that strong back and felt the warmth of the other's skin, Midoriya considered all the time he'd spent with the merman. How human Bakugou felt to him, felt beneath his touch. He eagerly allowed the other into him, in every way possible.

Midoriya spent even longer than usual in that pool, breathing in that merman, ignoring the moon as it reached it's peak. Just one more kiss, that was all he needed before he went to bed. That was always what he told himself, anyways.
