It happened when you were 5, isn’t that when all major things happened?
It had been a very cliche stormy afternoon and you had decided to go down into the beach, at the back of your parents house, to see if anything had washed ashore during the torrential rains that had happened earlier in the day, and that’s when you saw him.
At first it was just a glimpse of a tail, and you thought that maybe you had been seeing things; but then you caught sight of him again on a different day and saw his face; this time the image of his piercing red eyes remaining burned into your memory.
Time and time again you spotted him over the years but you had never gotten close enough to talk to him so you just left it at that- that you had seen a real life merman but that was about it.
The next time you saw him clearly was when you were 18.
He appeared to be the same age as you and had grown a lot since those days when you spotted him as a young merboy in the waves.
He seemed a lot more confident in himself and was propped up on his elbows on a rock just out of the swell of the waves, his intense red eyes watching you keenly as you walked towards him.
He was absolutely mesmerizing. Those eyes were always a killer, but as you inched closer to him you noticed more and more about him.
He had 2 bright red fins that projected slightly from his head, about where a human’s ears would normally be, and 3 small slits just behind them on his neck- his gills, you assumed, and you studied those before your eyes travelled down to his very toned torso and biceps to a very trim waist and on to a gorgeous turquoise and green tail that had a pearlescent tinge to it.
At first you just stared at him, unsure of what to do next.
“Do I try and talk to him? Does he understand human speech?” You thought as he stared you down with a heavy scowl.
“Stop staring at me you dumbass.” He growled, making the hair on the back of your neck stand on end.
“Y-You talk?” You stammered.
“Of course I fucking do.” He grunted with annoyance.
“And you swear?!”
“No shit.” He replied with a scowling smirk.
“I didn’t know mermen swore.” You said curiously.
“Not all of us do.” He replied with a shrug, “but don’t think that makes us any less than you humans.” He added haughtily.
“N-No, I didn’t think that for a second!” You stammered apologetically, “I think you’re really cool.”
“Hmm.” He hummed, smirking at you, “well you’re not wrong. How about you come down to the beach tonight and we can have some fun together.”
Something told you that wouldn’t be a good idea and you stalled.
“Come on.” He said sharply, “what? You don’t trust me? After all these years of watching me you’re not curious to know more?”
“W-Well you’re not wrong, like, I am curious but I don’t even know you…” You said as you took another step forward.
“Well come over here then and see for yourself.” He said with nonchalant confidence, “I’m … what’s the word you humans use? Harmless.”
The way he said it with those smirking red eyes screamed doubt but his alluring presence drew you in and before you knew it you were standing right beside him where he sat on his rock.
“Go ahead and touch me.” He coaxed in a low provocative voice and you did, running your fingers lightly over his tail. “Come up here.” He added and you stopped touching his tail so you could clamber up next to him.
Nervously you sat beside him and avoided eye contact as he tried to make direct eye contact with you.
“Oi.” He said lowly as he reached out and took your chin in the palm of his hand and turned your face to his, “look at me.”
You blinked a few times and looked at him, your body giving itself to him and you eagerly leaned in to him as he pulled your face up closer to his.
“Mmmmm?” He hummed approvingly, “obedient.”
“I… I’m not obedient.” You said in a small voice as you pulled your face away.
“I’m not done with you yet.” He said as he grabbed your chin again and pulled your face to his.
Suddenly you were kissing and his tongue slid in between your lips, his kisses a perfect mixture of rich and soft, numbing your mind to his will and you closed your eyes and enjoyed the slightly salty taste his lips and mouth provided.
Suddenly he pulled back.
“If you want more, I’ll see you tonight.” He said as he let you go and slid into the water with ease.
“W-Wait!?” You called, “what’s your name??”
“Bakugou.” He replied before diving beneath the waves and disappearing.
You sat there, shocked.
You had just made out with a merman. A hotmerman at that!
“It can’t hurt to come back tonight?” You thought as you slowly stood up on the rock and turned to head back to the house on the hill.
It was a warm night, thankfully, and you put your two piece swimmers on and slowly pushed your window open before slipping quietly out and running for the beach.
You hadn’t set a time with Bakugou but you figured he would be somewhere nearby and would come up when he saw you; which is exactly what happened.
You were heading to the rock that you had sat with him on, earlier that day, when he suddenly appeared; a strong wave carrying him up on top of it and he flicked the water from his spikey blond hair before looking over at you as you ran towards him.
“Uh, hi.” You panted as you got closer, “I didn’t get to thank you for the kiss earlier.”
“Don’t thank me until the night is over.” He leered and your heart skipped a beat as his red eyes glinted in the well lit night.
You glanced up at the sky and noticed the moon was particularly full that night.
“Is it a full moon tonight?” You asked him as you crawled up onto the rock.
“Observant, aren’t you?” He mused with a scowling smirk, snaking an arm around your waist and dragging you into his side before bending his head to the side of your neck and licking your soft skin.
“B-Bakugou?” You squeaked with surprise, “w-what are you doing?”
“Hop in the water with me.” He demanded suddenly, sliding off the rock back into the very dark, ominous looking water.
You looked in hesitantly.
“Sharks don’t come near me.” He commented, “if you stay close to me nothing is going to get you.”
Against your better judgment you sprang into the water and immediately his arms were around your middle as he pulled himself close in behind you.
“Nothing’s gonna get you but I will.” He whispered provocatively into your ear, licking the outer rim.
“S-Stop licking me.” You snapped, pushing his head away.
“You taste fucking sweet.” He grunted, “it’s a welcome change to salt flavoring.”
“So you pulled me in here so you could lick me all night?” You teased, half asking seriously, half joking.
“Oh?” Bakugou hummed, “you think I’m that innocent, huh? Well… time to prove you wrong.”
“Wait.” You said in a fear-filled voice, “what do you mean?”
Suddenly Bakugou ducked under the water and his hands slid down your waist and gripped your swimmer bottoms, pulling them off in one swift motion.
“Ah!” You gasped, desperately trying to grab them before he pulled them off completely but it was no use; you were now naked from the waist down. “What are you doing?!” You squeaked as Bakugou surfaced in front of you.
“It’s a full moon tonight.” He commented with a smirk, “surely you know what that means?”
“No?” You replied dubiously, “I don’t.”
“This is mating night.” He said, “we pick our female of choice and mate with them.”
“W-Wait but I’m a human?!” You spluttered, “you can’t mate me, you’re supposed to pick a mermaid!”
“I don’t like them, they’re not as interesting nor erotically pleasing as you.” He said lowly as his hands gripped your sides once again, his torso coming into contact with yours, “I can show you what a real merman feels like.” He added with coy seduction.
You blushed madly.
“I-But-We-Wait-This is moving so fast, I-.” You stammered, his lips cutting you off once again as he held you close and kissed you.
You gave in to him again, your core starting to throb the more you kissed in the water just off the shore.
Bakugou was a confident kisser and after spending adequate time on your mouth he slowly slid down your front and under the water, his kisses trailing down your stomach, to your lower abdomen and then all of a sudden his tongue was on your clit, licking and sucking as he wrapped his hand around behind you and held onto your ass.
“Oh god.” You moaned, body bobbing in the water as he expertly pleased you.
Breathing heavily you spread your legs for him and ran your finger through his hair before clamping down on his soft spikey locks and holding on, his head moving back and forth as he swiped his tongue all over your pussy.
After a while he came up and smirked proudly at you.
“See?” He commented once he saw the look of pleasure on your face, “If you liked that then just wait till I’m inside you.”
“Please take me.” You whispered needily, no longer holding back now that you were well and truly turned on.
“Don’t tell me what to do.” He grunted with another smirk as he hooked an arm around you and swam over to a semi submerged rock nearby, turning your body towards it and bending you over it as he swam around behind you.
Up until this point you hadn’t really thought about where his cock had been hiding but within seconds he had swum up over the back of you and something firm poked at your pussy entrance then forced its way between your folds and he was in and rocking furiously back and forth, his cock slamming hard and fast into your pussy.
“Ahhh~.” You wailed with pleasure, “Bakugou~.”
“Yeah~, that’s right, human, scream my name.” He rasped into your ear as he continued to fuck you on the rock.
“Oh god, your cock feels so good.” You cried, “f-faster.”
“Bet you didn’t know it could feel this good, huh?” He growled, “take my cock.”
You panted and moaned as he continued to thrust into you, the waves lapping around you as he doubled over you, biting lightly into your neck and licking your sweet tasting skin.
“B-Bakugou, I’m gonna cum.” You whimpered suddenly, legs spread wide so his cock could slam into you easier.
“Cum, human.” He uttered lowly, “cum for me.”
You arched against the rock, letting out a wail of ecstasy as he continued to thrust into you, his movements getting sloppier and his harsh breathing increasing then suddenly he released inside you, a very warm burst of cum filling you up.
“Y-You came in me!?” You panted, trying to look back over your shoulder at him to give him a worried look.
“Nothing will happen unless you come with me to the sea king.” Bakugou said as he pulled out of you, “I’m just a dirty siren that wanted to fuck a hot human, there’s no such thing as mate night.”
“You!” You spat with surprise, “you tricked me!”
“No I didn’t.” He replied with a scowl, “you wanted to be railed by me too, don’t even try and deny it.”
“Well…” you replied with a shrug, “guess we’re even.”
“But if you come to the sea king he can make you into a mermaid and you’ll bear my offspring.” He said, taking your hand and dragging you towards him as he sank slowly down into the water.
“Wait. No! BAKUGOU.” You said sharply, wrenching your hand free and quickly grabbing the rock nearby so you could climb out of the water.
Bakugou smirked from where he was still half under water.
“Almost had you…” you sneered, tossing your swimmer bottoms back up to you. “I’ll be back for more, human…”
“It’s Y/N.” You said with a small scowl, “and you won’t be back for more because I’m not getting in the water next time.”
“You know you can’t say no to a dirty hot siren.” He leered, sinking down while maintaining eye contact with you; the last thing you saw were his glowing red eyes as he sank backwards into the deep; slowly being lost from sight.
“No one will ever believe I got fucked by a siren in the ocean.” You thought with a smirk, reaching for some sea water to wash off his cum that was dripping down the inside of your leg. “I’ll see you next time, Bakugou.”
