“Bin, are you sure you don’t want to go with us?” The shorter looked up at Chan from his seat on the lounge chair, shaking his head, “I’m sure hyung. I may just go for a swim or something and then watch a movie. You guys have fun for me though.” Sighing softly, the older one nodded, pulling Jisung and Minho along with him.
The group of four were taking a vacation after finishing up finals and exams for college and Jisung thought it’d be a wonderful idea to go hit up the club they’d seen in the city on the way to the beach home they had rented. Changbin, however, didn’t feel like going. He wasn’t much for crowds anyway, but he was sort of really horny and the pool a couple of feet in front of him looked like it’d be cool enough to maybe make his boner go down. Plus, they hadn’t swam in the pool yet so now was the perfect time to do so without Jisung trying to drown him.
Hopping up from the lounge chair, Changbin made his way through the sliding glass doors and towards the front of the house to make sure the car was long gone before stripping completely and making his way back out to the pool. The beach homes were a bit farther apart and there was a privacy fence up, so he didn’t care about basically skinny dipping.
Frowning when he put one foot into the water to step onto the top of the stairs of the pool, he just sighed and went with it. The water was warm actually, but maybe if he swam around then it’d help keep his mind off his problem and hopefully it’d go down. But if anything, after a bit of swimming around, it seemed to make it worse.
His body felt hot, he seemed to just get harder if that was possible. “Fuck it,” he mumbled to himself before sitting on one of the steps and wrapping a hand around his cock. Changbin started with slow strokes, closing his eyes and leaning his head back as he began to think unholy thoughts, quickening his pace as he did so. It hadn’t taken long, between the warm water, how hard he had been and his thoughts, before he was releasing with a loud groan.
With his eyes still closed, and his breathing slightly uneven, Changbin missed the bubbles forming in the water. The slight blue glow that illuminated the pool. Feeling something sort of slimy touch his leg, he screamed. Not quite manly, might I add. As soon as Changbin opened his eyes, he was met with bright glowing green eyes. The creature lifted its face up a bit more from the water, showing its face fully. Green scales littered the creature's face, the hair was surprisingly a gorgeous blonde color that went down to its shoulders. As it stood up more, he soon realized it was a male, from the lack of chest, and because of the voice that came out of its mouth next, "Such a pretty human, hm?" Changbin gulped, how could a male sound so heavenly and look just so perfect? The creature stood up more, towering over the male that was still star struck. Only then did he notice all the tentacles that surrounded the male, the gills on his neck under his ears, his plump lips, more green scales littering across his toned body, the fangs in his mouth as he had spoken, the pointy ears.
Basically one of Changbins fantasies was standing right in front of him and he didn't know what to think. He watched as a webbed hand raised up and gently cupped his cheek, "What's your name pretty?" "C-changbin," he stuttered, "Yours?" The creature's eyes widened ever so slightly, this human was different from the other humans he encountered. He was small and muscular like he liked, absolutely adorable, pretty brown eyes, and he didn't seem to be scared of him like all the others were. "I'm Hyunjin, do you know what I am or why I am here?" Changbin squeaked as a tentacle started traveling up his leg, "um no?" Of course he knew he was some sort of sea monster or something but this guy didn't come off as a monster, yet. "I'm a sea monster, half human/half octopus, whatever you will. I'm here because you summoned me."
Changbin furrowed his brow, he did what? He unconsciously leant into the other’s hand as he began to rub his cheek with his thumb and he blinked up at him, "I did?" Hyunjin hummed and nodded, "You did, with your cum and your thoughts. This pool is linked with the sea. But enough with the chit chat, now that you’ve summoned me, I need to feed. Can you help me with that?”
Humming in thought for a second, Changbin nodded, why not? It wasn’t every day that any of his fantasies came true, he wanted to live a little and what better way to do that than with a sexy looking sea monster that was standing in front of him. He didn’t understand what he meant by feeding but at this point, Changbin would do anything. That was all it took for the tentacles to slowly travel up his legs, occasionally using the suction cups to suck at his honey tanned skin.
Moaning, Changbin kept his eyes on the other without having to be told. “Good boy,” Hyunjin praised, trailing his hand from his chest, stopping to pinch at the boy’s nipples, earning an even louder moan from him. Moans soon turned into a gasp when suddenly tentacles were gripping at his legs and arms, lifting the shorter up in the air. Cold air prickled at his skin as pool water dropped from his body, Changbin watched as Hyunjin eyed his body up and down as he made his way up the steps of the pool and sat at the top, pool water only high enough to barely go up to his knees.
Changbin moaned again, licking his suddenly dry lips as he eyed the long, thick, cock nestled between the others legs. It stood up swollen and proud, the tip a pretty pink and already leaking a little bit. Normally one would be jealous, or intimidated at the size, but not Changbin. He was actually excited. Honestly he had always struggled in the area of having sexual relations. He was a bottom, obviously, but everyone always saw him as a top and a top only. They’d take one look at his build, the size of his cock, and then laugh when he’d bring up that he was a bottom through and through and wouldn’t be able to top them. But just the thought of that alone and not including the tentacles being shoved in him made him drool.
Hyunjin willed his tentacles to bring Changbin closer to him, quickly attaching his lips to a nipple. Tongue swirling around the bud, he brought a hand up and started pinching at the other bud. Nipping at the skin, Hyunjin allowed his fangs to pierce his skin just enough to leave marks and bruises but not enough to draw blood. If Changbin thought he was in heaven now, he surely was when a tentacle wrapped around his cock, the slick from it easing the glide as it slowly started to stroke him. Another tentacle found its way toward his ass, rubbing between his cheeks to spread some slick before the tip of it started prodding at his hole.
Changbin was a whining and writhing mess, the tentacles around his wrists and legs tightening a bit so he wouldn’t fall. Everything felt ten times better, the mouth around his nipple, the biting and sucking, the tentacle around his cock, and the one now slowly fucking into his ass, going deeper each thrust. The burn from the stretch strangely felt amazing and he found he didn’t mind if tomorrow he wouldn’t be able to walk or sit. Hyunjin leant back on his hands, pulling away from the chest in front of him to watch as the boy was slowly coming undone.
Hyunjin smirked and groaned at the sight before him. Changbin was the epitome of a mess, drool was running down his chin, precum leaking profusely from the tip of cock, slick running down his thighs, bruises and marks already painting his skin beautifully the same way an artist paints a canvas. A bulge could be seen forming in his stomach from the tentacle in him, eyes rolling to the back of his head as it hit his sweet spot and aimed for that spot over and over. Hyunjin reached one hand down and started to slowly stroke his own cock, just enough for friction, wanting to wait until he got as much cum as he could from the boy before he gave him his own seed.
Feeling him clenched around his tentacle, Hyunjin had the tip of the other one open and encased Changbins cock, sucking the life out of it. The first orgasm shook Changbin to the core, moaning loudly and eyes rolling back even more, thighs shaking and toes curling, the tentacle around his cock milking him dry.
“Such a good boy, you taste oh so sweet and delicious,” Hyunjin praised as he brought the one tentacle to his mouth to taste some of the boy's cum. Changbin preened at the praise, already feeling fucked out, but still letting the sea monster continue with his menstrations to his body. Once he was calmed down from his high enough to continue, the tentacle in his ass started back up again, another prodding at the entrance as the one around his cock started back up with stroking his length. Changbin gasped at the stretch as the second tentacle started to enter, face pinched in slight pain. Hyunjin stopped another tentacle mid air towards the human's mouth as he spoke, “is it too much? Do I need to stop Binnie?”
Changbin whined and whimpered, shaking his head furiously at the thought of him stopping. It had been years since he last ever felt this full and sated. “N-no sir wan-wanna continue, please,” he moaned out brokenly, the two tentacles both hitting at his prostate back to back, as one would thrust in as the other would thrust out. Hyunjin hummed softly, eyeing the boy for a minute to gauge the situation, not wanting to overdo it. Something he’d never done before, he’d never cared before if he went too hard or not, always having needed as much cum as he could get to keep his strength up. But there was something about this human and he found himself caring more than he should, “very well then, pinch at the tentacle holding your wrists if you need me to stop okay?” He spoke softly, voice velvet smooth and calming, Changbin nodded, opening his mouth when the other tentacle started moving back towards his mouth.
He wasn’t sure what he was expecting the slick to taste like, maybe salty like ocean water but he definitely wasn’t expecting it to taste as sweet as it did, moaning around it as the tentacles in his ass and the one around his cock started going faster, he allowed the one in his mouth to move further down his throat, choking him in a way but not enough to prevent air flow. Two more reached up and began to suck at his nipples and Changbin swore he saw stars. Cum shot from his cock down the tentacle again like a waterfall, his whole body spasming as a third orgasm hit when the tentacles filled him up with some type of warm liquid, the sweet liquid going down his throat too.
Changbin gasped loudly, breathing unevenly as he tried catching his breath; he'd never cum this many times within a short amount of time. His body was still shaking and his breathing uneven as Hyunjin brought him down to sit on his lap, wrapping his arms around him as he slumped against him. Feeling fingers running through his hair, Changbin looked up through bleary eyes, mind already cloudy and fuzzy, slowly slipping into subspace. “Are you still with me darling? If you can’t go another round then that’s ok, we’ll end here and I’ll help you clean up hm?” He wasn’t lying, it really was ok if the boy wanted to stop here. He had more than enough from him to give him enough energy to keep going.
Words slurred slightly, Binnie pouted, “w-wan ke-keep going. Wan pease s-sir,” Hyunjin cooed, webbed hand still running through the boy's hair. “It won’t be too long darling,” he spoke softly as he gently laid him down on the pavement behind him, a few tentacles under him to keep his skin from being scratched. Hyunjin sighed as he finally had his warm velvety walls wrap around his cock, slowly thrusting in and out as he leant down and captured Binnie's soft lips with his own, moaning as if it felt like heaven. It wasn’t long before he was close, thrusts becoming sloppy, groaning loudly as his hips stilled, cumming deep into the boy under him and biting at his neck, unknowingly marking him as his. Changbin cummed again, his cock barely spurting anything out. He was so far gone and fucked out that he didn’t feel Hyunjin pulling out, didn’t feel all the cum and slick oozing out, or the sea monster lightly kissing at his bloated tummy. He didn’t see him retract his tentacles from his body or feel him lift him up from the ground, his head lolling to the side of Hyunjins shoulder as he was carried inside.
Hyunjin followed the boy's scent until he found a room that smelled strongly of him, then walking to the en suite and filling the tub with warm water and adding some scents and oils he saw off to the side. He wasn’t stupid, he knew how the human world worked, he’d had the sea witch give him a human appearance once before to feed his curiosity. Changbin babbled incoherently as he was lowered into the tub, giggling as Hyunjin began to wash him with a body wash he found. Hyunjin didn’t know it, but he was definitely looking at the human with heart eyes. Anyone could see how fondly he was looking at the boy, how much in love he was already even though he barely knew anything about the boy except his name and how well he took this whole ordeal.
Changbins eyes began to droop as Hyunjin rinsed the conditioner out of his hair, unplugging the tub he grabbed a towel and lifted Binnie out of the tub and dried him off the best he could, laying him on the bed soon after, rummaging through the dresser to find a pair of boxers to put on the boy. Changbins breathing even out as soon as his head hit the pillow, soft snores leaving his lips every so often. Hyunjin couldn’t find it in himself to leave tonight like he normally would. Heck normally he wouldn’t even do aftercare. He’d just fuck and leave, going back to his cave in the depths of the ocean until he was summoned once again. But again, this time seemed different. Deep down something told him it’d be okay to stay for once.
Maybe in the morning Changbin would complain about all the slime trailing along the floor from outside into his room but he found he didn’t care, he couldn’t help it anyway, he had no way of getting rid of his tentacles. And he never had mastered hiding them in his skin like most sea monsters like him did. Crawling into the bed, he sighed contently as Changbin clung onto him, burying his face into his chest.
Just what was this feeling?

Changbin woke the next morning, stretching his sore body, gasping as realized his dream had to have been real. If the arms wrapped around him, the pleasant ache in his back and ass said anything.
“Morning darling,” Changbin squeaked at the other’s morning voice, “m-morning,” he looked up at him, leaning in to kiss his plump lips when a loud thud and a “CHANGBIN WHY IS THERE SLIME EVERYWHERE?!” was heard, accompanied by a groan. Changbin looked back at Hyunjin and giggled before he gasped, “your ears and gills and everything are gone!”
“Wait what? That’s impossible-”
“CHANGBIN HYUNG ARE YOU EVEN LISTENING TO US?” Jisung yelled out again as Chan helped him up, “Whoops,” Hyunjin spoke, earning a giggle. Changbin was going to have fun explaining this. But first, he needed to see if he was going to be able to walk or even stand up from the bed.
