I really hope you all love the fic, would have been done weeks ago had the ac not died. But still 40min left of MerMay! I wrote this fast without a beta reader so please forgive any mistakes! The name Onyk is a reference to Onykia Ingens, a deap sea squid with an astoundingly long dick.)

Seaspark Aquarium was a very unique establishment. Not only did it contain the usual attractions that an aquarium housed, the tide pools, the sharks, a seemingly unending variety of colorful fish and corals and nudibranchs, but it also housed transient merfolk. The aquarium was situated on a flat outcrop of rocky land. Via submerged tubes it granted access to a huge tank to the ocean and merfolk below.

The tank was absolutely massive and had many different areas including a reef, a seaweed forest, a beach, and even a secluded sea cave. There were underwater cameras in most of the areas that live streamed what was happening on screens for the humans. Though the sea cave feed was restricted to adults only since the merfolk sometimes mated there.

The aquarium was just as much an exhibit for the merpeople as it was for the humans, they had underwater screens that allowed them to view the humans at play and at the food court. They enjoyed seeing and even communicating with their terrestrial cousins. There were several areas where humans and merpeople could talk face to face or via the cameras. Many of them visited quite frequently and made friendships with regular customers and their favorite staff members.

You had been blessed with landing a really good job at Seaspark Aquarium. Though it was entirely because you were the cousin of the curator of the establishment. You did janitorial tasks, including sometimes scraping the tanks, and occasionally you had to provide food for an exhibit. Even though interacting with animals or merfolk was not a common part of your job, there was one squid-man who had become quite friendly with you. Onyk.

Most of the squid type mermen shied away from human interaction, and really the aquarium as a whole, but not Onyk. He had always been a frequent visitor. A knowledgeable observer might even say it seemed that he had been hoping to find something there. The first few times he had gone had been out of pure curiosity about humans after hearing tales about them his entire life. But after his first couple of visits he was enthralled. Everything about the land walkers amazed him.

And then he met you and felt his heart flutter every single time he looked upon you. He frequently tried to engage you in conversation whenever he could and was always watching you, though often it was in secret. Onyk cherished your chats with him, he found you so interesting, even more so than he found other humans. He loved seeing you go about your tasks, it made him think of you cleaning his home as his mate while he went and got food for the two of you.

Of course if you had any say, that would never happen. Onyk, for some reason you couldn't quite place, creeped you out. No, it wasn't the head of tentacles he had in place of hair, nor the dark purple tentacles he had from the waist down, it wasn't his smile that showed off his dangerously sharp teeth, or his cyan blue eyes. No, it wasn't anything physical, just a weird energy he seemed to give off. Like a hungry animal hunting its prey.

You tried to be nice to Onyk, though you always tried to keep conversations brief and hurry on to other tasks that would take you out of his reach. Unfortunately he took your awkward stammers and clumsy rushing to zip away from him as you being extremely shy because you liked him. He sighed and stared at you longingly, head resting on his hands, as you rushed off once more. Clearly you were simply too embarrassed by your emotions to act rationally around him. Onyk had to find a way to get you to stop running off. As adorable as it was that you kept scampering off from your shyness you really needed to be closer to him.

Onyk had a brilliant, though simple, idea. It came to him right as you were in the middle of making another excuse to run away from him while the two of you were chatting in the beach area. He'd simply grab you. It wasn't the first thing he'd normally do, but you were just too prone to running off. It was more than obvious you needed him to make a firm and forceful first move.

"Well uh... it was nice seeing you again Onyk... but um... I gotta go check on the tide p-"

Onyk lunged at you suddenly with the speed and ferocity of lightning. He pulled you into the water and swiftly took you into the empty sea cave and sat you on the dry ground within. Yes, this would do perfectly for his purposes. It was a huge room that had an area for him to swim and enough space for you to run about and get exercise. This would make a lovely home for the two of you, he'd have to keep all the other merfolk out from now on but that wasn't an issue, they were respectful of claimed territory.

Once you caught your breath you were confused and angry at the sudden relocation.

"What the f-"

He interrupted you again, this time by pressing his hungry lips to yours in a passionate embrace. His long tongue slipped past your unsuspecting lips and explored every inch that it could reach. His saliva pooled in your mouth, claiming it. The offending muscle snaked down your throat before finally retreating as he broke the kiss, you struggled to find your breath once more.

"Heh, sorry for interrupting, I have just been waiting to kiss you for so long I couldn't hold back any longer!"

“What!? Why did you do that? Why did you bring me here!?”

“Well your shyness was making it hard for us to take things to the next step in our relationship, now you can’t let your nervousness get the better of you and make you run off!”

“Next step in our relationship? We have no relationship, you creep!”

“Don’t say that! Y-you just have the jitters because moving in is such a big step! Yeah, they’ll wear off soon I’m sure.”

“There won’t be a soon, I am going back to the beach!”

You started to head back to the water, but Onyk closed the distance between the two of you easily.

“But you can’t go! You’re just in denial and nervous, but you’ll love living with me, I promise. M-maybe I’m not moving too fast but too slow. That must be it, you must be all pent up and eager for my dick! So naughty~”

Onyk’s blush was evident even on his light blue skin. He swallowed your complaints in another deep kiss as he stood behind you and rubbed your crotch gently.

“We’ll do it in front of these cameras so everyone knows you’re mine now~”

And, indeed, the screens in the adults only section of the aquarium definitely picked up some viewers as the scene between you and Onyk unfolded.

Most mermen would have had trouble traversing land, but Onyk’s strong tentacles allowed him to maneuver easily enough. He peeled off your wet clothing and wrapped his arms tightly around your bare chest, rubbing and caressing you with greedy hands. His prehensile cock wrapped partially around your waist, held you close as it rubbed against you. At first you mistook the sensation for a tentacle before looking down and seeing it, the cock was tapered, icy blue and glowing at the tip, with the rest of it being dark purple.

Your shouts and screams were ignored as Onyk convinced himself they were just you being grumpy or maybe playing hard to get. The merman’s sharp teeth bit carefully at your tender neck as you squirmed. Most of his tentacles had wrapped around your legs, powerful suction cups firmly adhered them to you. They held you staunchly in place despite your best efforts to struggle.

The remaining two writhing appendages were busy with another task. They gently prodded and massaged your tight hole, slowly worming their way inside you. Your efforts to clench and keep them outside of you were rendered futile as they finally worked their way inside of you. They began thrusting in tandem back and forth within you, loosening you up well.

Your next attempt at protesting devolves into several lusty moans as he ministrations begin to elicit pleasure. It’s all the confirmation he needs that he has been right all along and definitely went about everything in the right way.

“Your mating sounds are so lovely,” he said as he nipped at your ear.

His tentacles suddenly withdrew from your lovingly stretched hole, leaving you involuntarily whimpering at the sudden removal.

“Awe, don’t worry, love. I have something far better to put into you~”

You snap out of it when you hear those words and feel his cock move itself from your waist and start wiggling against you in search of its target.

“What!? No, please do-oooh~ Aaah!”

When it found your entrance it deftly slithered right in. Much to your unwilling pleasure.

Onyk chuckled.

“I knew you just needed some good dick~ You feel soooo good. You were made for this!”

When you happened to look up at one of the cameras you blushed and looked down. The room that monitored the sea cave was now packed, everyone enjoying the sight. The aquarium was already at work recording with plans to put it on their website for sale.

You couldn’t help the lewd cacophony of noises that tumbled from your mouth as the thick slimy cock thrust back and forth inside of you.

“I love you. I love you. I love you. I love you. I love you. I love you. I love you. I love you. I love you!” Onyk chanted louder and louder until he slammed into you hard, filling you up with warm viscous semen at the same moment that you were shuddering from the strongest orgasm that you had ever experienced.

You were far too dazed and overstimulated to realize what was going on in that moment or what you were saying, but on autopilot you mumbled back what your brain thought it was supposed to when someone told you that they loved you.

“I l-love you too…”

Onyk was overjoyed to hear those words from his beloved human. He pulled out of you and laid down on the floor of the cave, pulling you close to him and resting your head on his chest. His webbed fingers gently caressed you as did both the tentacles that made up his "hair" and the ones below his waist. Cum slowly ebbed out of you and onto him but he didn't mind, the two of you would just get messy again the second you came to your senses. He nuzzled into your hair and gave you dozens of little kisses. Your mind was too blank and your body too exhausted to do anything but drool a bit on his chest while he cuddled you.

His head was swimming with all of the things the two of you would do together. Sharing meals, chatting, mating. He couldn’t wait to wrap his cock gently around your neck while at the same time plunging it down your throat and having that pretty mouth of yours suck it until he was feeding you his cum. Maybe the two of you could try it when you woke up.

Meanwhile onlookers on the viewing screens were putting away their cocks and slipping their fingers out of their pussies with the spectacle now over, but word soon spread and tourism was up over 300 percent! Scientists the world over were interested in documenting this rare species of merman having sexual relations with a human. Grants were given. A great raise and credit to your cousin, the curator.

It was even considered a diplomatic victory for merfolk and humans!

Everyone came to the consensus that on all fronts, but yours, it was far too beneficial and lucrative to make sure you had to permanently stay in the sea cave for the rest of your life with Onyk. At the very least they equipped the habitat with amenities like a proper bathroom, tv, video games, and human food. The sea cave area was also expanded, and you were afforded some privacy, except for most of the times that your “husband” Onyk was spilling his seed into you. That’s what people wanted to see.
