THEY ARE SOOOO AMAZING ♥️ I LOVE ITTT I'M GOING TO READ THEM ALWAYS ♥️♥️♥️♥️ and *take a deep breath* i would like to make a request about my babyboy Rin :3, i would like to request some headcanons about a Merman!Rin with a female S/O, like... An AU! (Can you split between SFW and NSFW headcanons plsss?) Thank you and good luck with your other requests ^^ have a nice week!
Merman!Rin
Our precious boy is no ordinary merman... no, no, no. He is part SHARK. With the sleek but sharp scale, and the twist in his hips as he swims that makes him captivating to watch.
He meets his s/o when he finds her drifting out to sea on her board. She laid on it for a bit of sun, and the slow rocking of the ocean slowly carried her farther away from shore. When the board is pulled along the coast and near some rocks, Rin pops up to stop it from hitting the spiky rockline.
His S/O is confused when the sow rocking of the ocean suddenly stops with a jerk. She looks around and nearly flips off the board when she sees a shark fin sticking out of the water. But even stranger are the human hands that are holding it.
When Rin pokes his head out of the water, he half expects the young woman to scream at the sight of him. Instead, she sputters, and then touches him. He scowls and flushes under the odd reaction.
She is completely fascinated with Rin, and starts firing off a thousand questions. He is slightly overwhelmed with her enthusiasm, and just pops back down into the water. She wants to go after him, but finally realizes how far she is from the shore... as well as how close she came to crashing into the rockline.
Rin is shocked to see her come back everyday looking for him. She brings a board paddle to move around easily in the water, looking around the rocks to see if he shows up again. He is conflicted about showing himself again.
Things change when she arrives at the beach one day to see water poachers terrorizing the waters. The grab fish left and right, slicing them apart in the water and dragging bits and pieces onto their boats. She is immediately sickened and angered by the vicious violation of the waters. Her mind flashes to Rin, and she bolts into action before she can think.
She is out in the water threatening the, calling up the coast guard and local protection organization. They threaten her back, and when they flip her small kayak into the ocean, she realizes how outnumbered she is. They threaten her with their machetes, and yelling at her to mind her own business. She can’t risk grabbing onto their small boats, and bobs in the cold and filthy water. She startles wen she feels something brush against her under the water.
Rin noticed the commotion, could smell the slaughter from farther out in the water. Upon further investigation, he sees and hears the poachers making a mess of his home. The beautiful fish and healthy reefs are being torn apart for their own greed. Rin’s blood boils and he decides his next plan of action. He doesn’t get very far when he sees his S/O plow into the water and start to threaten them. His stomach plummets.
When they knock her into the water, Rin is right there. He is watching her from below, and taking in her natural scent. He knows none of the blood is hers. Thank goodness. With his large, muscly body, he starts to hit against their boats. They have small motors on them, so he must be careful with every move.
The jerky interruptions startle the poachers, and they quickly get out of the water. They have more than enough in their illegal catch, and would [refer to get lost before authorities show up. They leave the young woman in the water, and disappear. The only evidence left of their presence is the bloody mess left floating in the water.
S/O floats in the water with tears streaming down her face, her body defeated and her heart aching. Rin pops up out of the water and is startled by this. He moves close to her and wraps his arms around the shocked young woman. She easily slumps against his form, and he is surprised by how much he enjoys her touch against him. Her skin is warmer than his, and there is something about her scent that soothes him.
When she is ready to talk, they have a long chat about everything that happened. She says that she has been looking for Rin, and is glad nothing bad happened to him. His heart beats out of control at her ords, and she loves the flush that spreads over his cheeks.
They meet up often at the beach to get to know each other better. Rin preens proudly when he finds out sharks are her favorite animal. She gets just excited when Rin admits that she is the only human he has ever found so interesting.
When they get close enough, Rin admits that he likes having her in his life, and hopes they can be mates.
Long swims in the water until his S/O starts getting cold. The smooth motions of his body fascinate her, and she loves pressing against him as they swim around the gorgeous waters. She is also fascinated by the fact that they can swim in groups of other sharks without seeing her as a threat. She loves the wild interaction.
Rin loves to swim into deep waters and bring her things that have been lost to the sands long ago. She is surprised when he brings her gorgeous shells, numerous pearls, and even a few pieces of very expensive jewelry. She wonders if it’s okay to keep such lavish gifts, but Rin assures her that they are a token of his care for her. Plus, they have been lost so long, probably no one would come looking for them.
S/O doing everything in her power to get the area monitored and protected. Not only is she concerned about other people finding Rin and exposing his existence; but she would hate for a repeat of the poacher incident. It takes a lot of paperwork and money, as well as time and dedication. Eventually things follow through, and she finds out how much of a crybaby Rin is. He doesn’t stop blubbering on her for a long time, but she loves every moment spent in his arms, knowing that nothing can happen to him.
NSFW BELOW! PROCEED WITH CAUTION!
Their first kiss is spontaneous and awkward. They are speaking close together, the conversation having gotten intimate, when suddenly Rin lunges forward to kiss her. His shark teeth bump against her lips and she has not time to move her own in any response before he pulls away. She giggles at his embarrassed expression, but helps him out with a better second kiss. She holds his face between her palms and slowly leads him into a softer kiss.
Rin becomes extremely handsy with his S/O. Not necessarily in a perverted way, but he has become comfortable with her touch, and enjoys touching her in return. She can expect to find his hands always seeking out her waist, her hands, even her legs. He also loves the flush on her cheeks when his hands start to roam place beneath her bathing suit. Stroking up her legs until his fingers slip just beneath the edge of her bikini bottoms. She tries not to moan at his touch, but her expression tell him everything.
At first, most of the touching is done by him. He finds his S/O’s body fascinating, and wants to explore every inch of it. When he pulls the top from her body, he immediately brings his mouth down to her chest. Her nipples pebble instantly in the cold water, and he can’t help but kiss from her collarbone to her breasts. He licks and nips around the sensitive globes before popping a nipple into his mouth. S/O is surprised to find that his mouth is actually warm, and she loves the sensation of his rough tongue circling around her achy nipples.
His fingers slip under the material of her bottoms, feeling out her slick folds with fascination. At first, he rubs a little rough against her, but she is more than happy to guide his hand and show just how she likes to be touched. He is nearly impossible to stop the first time he strokes her to an orgasm. The way her body shakes and clenches around his fingers has him getting aroused in a breath.
However, his S/O doesn’t waste time in asking to pleasure him as well. He is a little shy at first, unsure about how she will take the experience. He has seen a few nude men on the beach, and knows that he doesn’t function necessarily the same way as them But he trusts his lover, and feels good that she wants to pleasure him as well.
She is shocked at first, when he shows her the slit that rests a little ways below his pelvic area. He takes her hand and strokes her fingers over the slit, and she gasps when she realizes they part and shiver with pleasure. She considers the way she likes to be touched, and soon has him writhing against her. She is obviously more than pleased.
When something starts to poke out of the slit, she is shocked and thrilled to see he has two cocks! They are both long and smooth, pointed at the tip and thick around the middle. She finds herself immediately getting wet at the thought of getting fucked with them. She had never considered before that she would be into something like that, but because it is Rin, she knows she will love it.
They spend a little more time getting acquainted with each other, grinding against each other in the water. S/O is a littl bummed when Rin seems to shy away from penetration but he reveals it’s only because he doesn’t wish to hurt her. She reassures him that they can take things slowly and work everything out as they go along. It is about discovering how they both can work together to feel good, and she is more than eager to get started.
She is hot and tight around him the first time he penetrates her with one of his cocks, She is shocked by the size and length of him, but is mewling into the air as he moves slowly within her. Holding her afloat in his arms, he is flushed watching her face contort with pleasure. The tight squeeze of her pussy around him sends him into a frenzy of his own. She doesn’t realize how violently his tail thrashes in the water as he pounds into her until she is cumming.
The white flashes behind her eyes, and as she comes down to oversensitivity, he is still thrusting into her. His tails kicks and throws water in every direction as he pistons into her with all of his strength. She will probably come again around him by the time he reaches his own peak, and she is shocked by the power behind his ejaculation.
While human men let out spurts that range in size and duration, Rin lets out a constant, steady stream of cum that has her feeling overly full. On top of that, it swirls around her body as his other free cock also ejaculates just as much. She is so shocked by the great amount that it has her loins tingling again with interest.
It takes them a while of being together before she tell Rin that she wants to be double penetrated by his cocks. At first, he is shocked by the admission, but he is also immensely turned on. She admits to having practiced some anal exercises to prepare herself for him, and even reveals a small bottle of lube she had the insight of bringing along.
When he fits both of his cocks inside her, she has never seen his face so fucking blissed out. The sensation of er tight, hot holes squeezing around both his cocks has him nearly cumming right away. The first time he doesn’t last long, but is satisfied when she is thrown over the edge just as quickly. While not something they indulge in every time, it is something they revisit frequently in their sexual ventures.
It is almost impossible for his S/O to give him a blowjob. While she can place kisses against his cocks and give him a few pleasurable licks, she can’t hold her breath long enough to blow him. However, she is pleasantly surprised when he vanishes beneath the water and attaches his mouth to her pussy. He can bring her to multiple orgasms without running out of air, and she thrills in every opportunity he takes to do so.
She also loves to rub her pussy against his slit when they get around. Something about their slits running against each other has her getting hot in seconds. She was pleasantly surprised to find that his cocks could slide right into her pussy if she mounted against him firmly enough. Again, not something they do all of the time, but they enjoy the special little tricks only they can manage.
Thank you @azusa8chan for the wonderful request. This was wonderfully creative, and you are seriously the sweetest thing that has dropped into my inbox in a long while. I hope you enjoy how this came out. I got a little carried away. I hope to see your lovely icon in my inbox again.
