------------------------------------------------------------------------------

A side effect of being surrounded by marine life was that I didn't have to be near people. I could just swim and survive on the land - using my quirk, of course. Without it I'd drown and rot, but that was a small detail.

Quirk: siren

Allows the individual to breathe underwater, hold their breath for long periods of time, shapeshift into a fish hybrid and to take on mermaid-like properties. The user can also sing to lure people and other creatures to them, having a brainwashing effect. The user is also able to communicate with sea life, manipulate water and the weather.

So that's what I was doing. I went to my local beach and just dived in after finding a cove to store my stuff. After all, just because I was immune to the pressure and the cold of the water didn't mean I wouldn't be freezing and damp when I came out.

As soon as I entered the water I felt my body relax. My skin gained a shimmering hue as my skin adapted and scales formed across my legs as they turned into two tails and a tail sprouted from my coccyx. My feet slowly grew fins as my fingers grew webbing, claws and fangs protruding from my body sharply.

I could have a mermaid tail if I wanted to. Much like how I could have more webbing and fins across my arms and legs, but I didn't see the point. It was a more painful process for little reward.

As per usual I took my deep sea camera with me to snap pictures here and there. Every now and then I'd spot a fish or a beautiful bit of reef to take pictures of. It was very peaceful.

However I was brought out of the moment as I felt the hairs on the back of my neck stand on edge as I surveyed the scene. I was being watched, for sure, but by who I couldn't see. It's not like there were any divers nearby, so it had to be a predator. But, again, there was nothing of the sort around.

I huffed to myself before going back to taking pictures. However I kept my guard up and kept sneaking glances around as I did.

Todoroki was fed up. Another argument with his father led to him storming out with angry clicks sounding behind him. He could only take so much from the man who seemed to demand respect without giving it to others.

So he left. The safety of his pod was behind him as he reached shallower ocean to try and get away for a bit. He just needed some time to process everything.

Todoroki's father wanted him to get a mate, and he wasn't waiting for it to happen naturally. So he interfered with his social life, again, to the point that it was preventing him from searching for his mate at all. Not that his father cared - he just needed Todoroki to find someone and settle down, whether they were truly his mate or not.

Todoroki wasn't like that. He couldn't just settle down with just anyone. It needed to be someone he cared about. Someone who could be a companion - a friend. Not just a lover to populate the dwindling numbers of Sirens.

That was when he caught sights of you.

Darting out of sight he hid behind a deep rooted part of the reef as he eyed you with curiosity. Your strong tail and slim, delicate leg-like tails practically fluttered around you as you put a weird looking box to your face before pressing a button.

Todoroki looked at you like you were crazy. He wasn't sure what the device you held was, but he wanted to know.

It was then he took in your appearance further. You had (H/L), (H/C) flowing around you. You had claws, much like him as well as little fins and webbing around your ears, hands and along your body. But that was where the similarities ended.

He'd never seen a creature like you before. Even when he'd come out here before, there was nothing remotely similar. Hell, him and his pod looked more similar to you than anything he'd seen before, and yet the differences were vast.

So he couldn't help his curiosity as he dared to get closer.

'Just another look…' he told himself as he inched closer, carefully hiding behind the reef again, waiting for you to move.

He continued to stalk you as you got deeper into the ocean and this lasted a while. It got to the point that any light that permeated the waters had gone - but that didn't deter you. It's not like you couldn't see in the dark, much like Todoroki.

Todoroki noted that down in his mental checklist of similarities, watching as you discarded the camera across your chest. From there you began to swim, getting deeper and deeper.

Todoroki wondered briefly where you slept. It was getting late and he knew he'd be in for a bollocking if he didn't turn up soon - but he wanted to wait this out to find out where you were going to go.

So he did - and it paid off.

Eventually you realised how late it was when you checked your watch. Concluding you'd had your fun, you spun around and swiftly made your way back to the cave that held your belongings in it.

Todoroki followed slowly, keeping his distance. He didn't want you to spot him just yet but when you entered the cave he found himself peeking his head up to get a good look.

To his horror he saw your tail recede and your fins thin out until they were able to be dusted off your body. All your scales vanished leaving a (S/C) hue to your body.

He quickly vanished once you began to get changed, feeling the heat rush to his cheeks. Still, whilst he laid in his bed he thought of you.

'A human…?' played around in his mind like a reel.

He'd seen humans. But never ones like that. They always had diving gear on - weird masks and large tanks on their backs so they could breathe.

They certainly never had fins and scales.

Eventually Todoroki fell asleep. But his mind never stopped thinking of you. He concluded to himself that he was going to see you again.

He promised it to himself. And Todoroki didn't have to wait long.

It was the day after the next. I stretched as I removed my clothes, carefully placing them in my bag before putting my bag in the dry part of the cove I'd found. From there I jumped into the pool at the back of the cove and swam towards the ocean with my trusty camera.

I was determined to get some more pictures of interesting marine life for my niece. She loved the camera so much last time, so I made a promise to find more for her to enjoy the next time I see her.

I was not disappointed as I neared the reef I was at the other day. But this time I planned to go further, having more of the day to explore.

It wasn't long into swimming that I felt that eerie sensation of being watched again. But this time, when I looked, I spotted a shimmering colour of red and white darting away from my vision.

Snapping my gaze towards it, I saw nothing but a seaweed garden. That was, until I neared.

I caught the movements of a mixture of red and white scales belonging to a huge tail. It has nothing on my tails in size comparison. But when I reached out to touch it, suddenly it jumped back and away.

I gave chase, following the creature with curiosity. However, with his superior tail, I was struggling. So I did the only thing I could think of.

"Hey, wait!" I clicked loudly in his direction.

That caught his attention, causing him to stop sharply and turn back with surprise. I grinned when I realised it worked and waved at him.

The man was a mermaid. A real mermaid. And I couldn't believe my chances.

Todoroki hesitantly waved back as I squealed to myself much to his confusion. He didn't mind having my attention, but found it slightly confusing as he moved some of his hair out of his face.

It was then I greedily took in his appearance. Red and white split hair, pale skin and sharp features. He was downright handsome, even as a fish-man.

"Uh, hi!" I beamed, clicks emanating my excitement effortlessly. Todoroki hesitantly replied back, but replied back he did.

I was dying inside.

I dared to, slowly, swim forward. Todoroki didn't move, but his hackles were still noticeably raised. So I was careful in my approach as I looked up at him.

"Are you a mermaid?" I begged curiously. Todoroki frowned at this before shaking his head.

"Siren." He responded curtly, "Are you a human?" I nodded.

"Yep! I don't look like it at the moment because of my quirk." I shrugged. Todoroki looked at me, puzzled, earning my explanation, "It's like a superpower people evolved to have. Mine is called Siren, funnily enough. It's what allows me to come down here and talk to you!"

Todoroki was baffled. Sure he'd seen the odd human once or twice, but they'd never had any kind of special powers. At least, not to the eye. That being said, he hadn't seen humans for a while and the memories were hazy at best. They could've had two heads and he wouldn't remember it. Humans never bothered his pod so he never bothered with them. It just didn't matter to him.

His eyes drifted across my body curiously. When he reached out I tried my best not to flinch at his touch, letting him trace my scales around my arms and shoulders. When his hand reached up my neck and towards my face I felt my cheeks flush at the intimate contact.

He was gentle in his pursuit. And I found myself tracing his light fins across his arms and reciprocating his light touches, doing my own investigations.

Todoroki has lovely fins across his arms, back and tail. They emanated the same colour scheme as his tail - reds and whites, though the way they shimmered gave him a milky tone. His skin was pale and glowing with the same sort of hue as my own.

Intrigued, I analysed his face as he analysed my own. Todoroki had one grey eye and one turquoise. His brows were matching his hair and he had next to no colour to his skin, although it was freckled with pale, moonstone-like scales. I moved my hands to trace his ears ever so delicately, awed by the thin fins that existed in place of ears.

"You're beautiful." He commented as he traced my chin. I immediately baulked, pink rising to my cheeks - something he noticed quickly and traced with a clawed finger, curiously, "Why are you pink?"

"Uhh…" I squeaked, "We do that when we're embarrassed."

"Why are you embarrassed?" I shook my head.

"It doesn't matter…" I muttered as he gazed into my eyes. I wasn't sure if he didn't get social cues or if he meant this to be as intimate as it was, so I cut him some slack and looked away, cheeks still flushed as he watched me.

"What's your name?" I begged curiously. Todoroki hummed for a moment before responding.

"Todoroki Shoto."

"Nice to meet you. I'm (L/N) (F/N)." I greeted, holding out my hand. When he looked at it, perplexed, I giggled and took the initiative to grab his hand and shake it. He returned the gesture once he caught on, but found it confusing nonetheless.

‘Is this something humans do when they meet one another?’

Todoroki's face moved back to the box on my body and poked it, making me giggle.

"Do you wanna take photos with me?"

"What's that?"

"Photos are renditions of things. Look." I beamed, showing him the screen, "I took a picture of the coral and now I have a small version of the image in the camera."

"Ca-me-ra?" He repeated with a foreign tongue. I nodded.

"That's what it's called." I beamed, "Do you want to try?"

Todoroki watched as I removed the device from my body before passing it to him. He held it awkwardly, trying his best not to break it as I showed him how to work it.

"Does it hurt?" He begged hesitantly. I shook my head.

"No, not at all!" He nodded before pointing the camera as he looked through the lens.

To my surprise, his first picture he wanted to take was of me, so I posed for the camera. When he took the picture he immediately looked to see the image across the screen with awe. I giggled at this before offering to take his picture.

"Okay." He smiled, passing the device back to me. Immediately he gave a peace sign and a bright smile full of sharp teeth. It was a beautiful, though uneasy, sight.

"Done!" I beamed, passing the device back to him so he could take a look.

I realised quickly that Todoroki likely never had seen himself before as he traced the camera. I smiled as I watched him mimic the motion on his own face as he beamed down at the device.

I couldn't get over his excitement and wondered more about him. Does he speak English? What did he know about humans? Are there more of him?

"Do you have family?" I begged curiously as he eyed the different pictures I'd taken whilst being here. He looked up at me for a moment before looking back down at the camera.

"Yeah. We call them pods." He mumbled, "They don't know I'm here."

"Why are you here? It must be far out from your home?" He nodded.

"Came here to get away." He admitted, looking to the side, "To be alone."

"Were you here two days ago as well by any chance?" He nodded.

"I saw you with this." He waved his hand, "But was worried about approaching." I nodded.

"Understandable."

"What is your pod like?" He begged, giving me back the camera. I paused at that, thinking for a moment before responding as I discarded the camera back to my body.

"They're fairly understanding." I mused, "We're quite similar. Each of us all have quirks related to the sea or water. So we spend a lot of time near the beach or lakes.

"I don't live with them anymore so I see them less than usual."

"You don't live with them?" He begged, surprised. I shook my head.

"Once you turn 18 you're legally an adult. You might live with them for a bit but generally people move out to their own place. My brother has his own pod now that he has a baby.

"Is it not the same for you?"

"We live in pods together. Never split up." He shook his head.

"How old are you?" I begged curiously. He tilted his head at me before answering.

"24." I nodded before telling him my age. He nodded slightly.

"Do you like your family?" He begged, swimming around me. I followed him with my gaze as he circled me and giggled at his enthusiasm.

"I love my family. We're very close, all of us despite the distance." I hummed, watching as he paused his pursuit to look closely at my tail.

"I'm not very close with my family." He admitted carefully as he rounded back to meet me face to face, making me jump at the proximity, "My father is overbearing."

"I'm sorry to hear that."

"He's determined for me to mate with a random female to continue to genepool." I frowned at this.

"That sounds awful. Do you mate for life?" He nodded, making me deflate, "That sounds incredibly oppressive." He nodded. I leaned back onto my back and looked up at him as I thought over the next question carefully. However he beat me to it.

"Do you have a mate?" I shook my head.

"No." I hummed, kicking my tails slightly to keep afloat, "In my world we don't have mates per se. We have partners that we marry."

"Marry?" He begged slowly. I nodded.

"It's a societally recognised partnership. Like a mate but with legal standing."

"That sounds nice." I nodded.

"Marriage is very serious. But it's also very special, in my eyes anyway. It's like the end goal of a relationship for humans."

"Do you mate for life?" I hesitated at the question for a moment.

"We're supposed to but it's not very common." I scratched my head, "The rate of people annulling marriage is over 50 percent."

"That's rather high." He mused.

"Yeah it's not good. But everyone is looking for 'the one'. It just doesn't end up being the person they choose to marry."

"How do you annul a marriage?" He begged, confused, "Is it not like mating for life?" I shook my head.

"It's a commitment, but you have the choice to leave. However it's difficult and a long, arduous process."

Todoroki and I continued to chat aimlessly into the night. I learnt that he could speak English and that his family contained his three siblings and two parents, but that they had a wider society that they lived in with other Sirens. He even gave me a sample of his singing voice, which was exactly as alluring as one would expect from a Siren, so it only lasted for a few seconds to prevent me from falling under his spell.

It took me a while to realise how late it had gotten given how dark it was down here to begin with. So I took him back to the cove where my things were which was when he admitted he had followed me here the other day.

I didn't mind. Todoroki was just being cautious and that was understandable. I'd have been the same in his position.

"Will I see you again?" I begged as I dried myself and put my dress on over my swimsuit. Todoroki smiled at me.

"I hope so." He admitted, "When are you next visiting?"

"Tomorrow?" I offered, earning a nod.

"I'll be here." I grinned, beaming down at him, who was still floating in the water as I put my shoes on.

"It's a date!"

Todoroki flushed at that insinuation. However I was already leaving and waving his way before he could comment on it. So he left with butterflies in his stomach and his mind reeling.

Todoroki knew little about human customs, but he did know about them. Dating was the next level of courtship when you show interest in a mate in his world. Did you think of him like that? They had only met today, officially. Was it all too soon?

He wasn't sure but he couldn't deny the feeling she made him feel. She listened to him and offered advice. She seemed to care about his wellbeing and his family life which was more than he could say about any of the females that his father had forced him to interact with.

He wasn't sure what his father would think of this. It wasn't unusual for Sirens to fall for humans, but his father was rather persnickety and wanted a brood from him. She could give that, but it would mean leaving his pod and taking on legs and living on land with her, most likely.

So he waited with baited breath. He couldn't sleep from excitement so he was up at the crack of dawn and swimming away from his pod. He wasn't sure how long he waited, but it was long enough.

"Shoto~!" I sang as soon as I entered the cove and spotted him, "How are you?" I begged as he sat on the ledge. He turned and smiled, small chirps sounding from his throat at the sight of me.

"Well. How about you?"

"Good!" I beamed before removing my clothes - an act that Todoroki thought was rather intimate for humans.

Sure, he'd seen humans in swimsuits before. That's par for the course by the seaside. However, he'd also seen humans mating practises. So he knew that something important was under those swimsuits.

His cock twitched at the thought.

"Ready to go?" He nodded before diving in, watching as I jumped in with a cannonball.

I giggled as I felt my body change. Todoroki watched with awe as my legs changed to tails and fins and my tail grew out. He couldn't help himself as he came close and traced the outline of my skin as it turned into scales.

I squeaked in surprise at the contact, but didn't move away. He watched as my skin turned that beautiful, reflective hue and felt around my body gently. He was careful and deliberate in his movements as they lowered towards my tails.

I couldn't help but do the same back, tracing the large scales that met his tail. I watched him closely as he seemed to relax at the contact.

"May I see your tail?" Todoroki's eyes widened at that, though I didn't notice as I traced his scales by his hip bone. However it soon turned into a smirk as he nodded, which I took as encouraging.

What I didn't realise was the intimacy of such a request. I was solidifying my interest in the Siren without even realising it, and Todoroki was feeling more unsure about how much I knew about their customs. But he wasn't deterred.

I dived down, slowly gliding my fingers across the luscious scales of his tail, going right down to the fins at the bottom and back up. I couldn't help my greedy pursuit, knowing I may never get this chance again.

When my hand traced along his hip bone again, he grabbed my hand gently and pulled me to him. I blinked but followed as he guided me up before he placed his hand along mine.

Todoroki's hand was much bigger than mine. His fingers were slender and long, his webbing even longer. His pads were more ragged from years of use for hunting and fishing whilst mine in his mind were soft and delicate.

"Follow me."

Todoroki pulled me to him and I wrapped my arms around his neck as he propelled us forward, his arm around my waist tightly. He was significantly faster than I was so I let him drag me to wherever he wanted to take me as I took in the sights.

We went in the opposite direction to where we had originally met and went deeper than I was anticipating. I knew that by the time we were finished it would be dark before I could get back to the cavern. But I didn't mind.

Eventually we came to a cave system. Todoroki told me to close my eyes and that he would guide me, which I did with a few squeaks when I nearly smacked into a wall like the idiot I am. However it wasn't long before he told me I could open them again. And when I did I was in awe.

Inside the cave system was one particular cavern that was illuminated by all kinds of sea life and algae. It was sloped so that there was some out of water area that was covered in soft moss and plant life. Lining the natural grooves in the wall was some kind of shiny stone or jewel that made up most of the cave.

It was beautiful. Breathtaking, even.

"Shoto this is amazing…!" I awed, earning a small smile.

"You like it?" I nodded feverishly.

"I love it!" I beamed turning back to him and hugging him, "You really know the best places to visit, huh? I need to take some pictures of this place!"

Todoroki watched as I rushed off to start taking pictures with an amused smile. He felt proud - the courtship was going well. All he needed to do now was find an appropriate gift for me to accept and I will be his mate.

'Mate…' he hummed. He liked the sound of it, smiling fondly in my direction as I took pictures of the passing fish with glee.

Todoroki had in mind what he planned to give me. He just needed to find the right one. He knew that pearls were valuable to humans, for whatever reason. So he was going to go hunting to find the biggest before the next meeting.

"Shoto, look!" I cheered, catching his attention. He swam over, curious to see a male seahorse giving birth as I took pictures of the miraculous moment, "I've never seen this in person!"

Shoto raised a brow. He hadn't expected to see that either and was watching with intrigue at the sight.

'Is that what it'll be like?' he pondered with fear at how the seahorse was shooting out young like cannonballs over and over until, eventually, the pouch the younglings were in was empty.

Todoroki didn't like the idea of being the one to carry the young but then he paused that thought, thinking about how nice it would be to feel the baby close. However, he looked over at me and paused his thoughts again.

'She's human.' he noted, 'She won't have an egg duct, will she?'

Todoroki realised that he knew very little about female anatomy. Sirens had stopped interacting with humans decades ago, way before he was even born. There was a time where humans were prey - for sex, food or both.

So he had little understanding of what sex organs I would have other than a uterus. It was simple, in his mind. However, I wasn't like a regular human, he concluded. So it was possible I had other sex organs he didn't know about.

It made him anxious, but he was sure he could figure it out.

From there the tiny seahorses dispersed and left towards safer areas - all the while I was taking photographs.

"Did you know this was here?" I begged curiously. Todoroki shook his head.

"No." He admitted, "It's quite the sight."

"I don't think I'll be shooting children out like that." I deadpanned, dryly, earning a chuckle.

"I would hope not." He admitted before looking my way and deciding to be bold, "How do humans reproduce?"

I froze at that question. How the hell was I supposed to explain that? Did he mean how we do the vertical tango or did he mean how we actually have babies?

My head was reeling and I decided to air on the side of caution.

"Men have penises and women have uteruses." I started, slowly, "Men produce sperm and women have eggs. Once fertilised the woman keeps the baby in her uterus until they reach maturity, whereby she then gives birth.

"How does it work with you guys?"

"The same." He admitted before adding, "Although men and women have both eggs and sperm and can have children outside of the womb, with or without sex." I blinked, intrigued.

"How does that work?"

"With difficulty." He noted, taking a seat down on the ground casually. I followed him, folding my legs under me, "You have to watch the eggs constantly for 9 months, making sure to keep oxygen flow constant."

"Like an octopus?" He nodded.

"Exactly."

"Sounds troublesome." I noted, earning another nod. I paused, "Doesn't that mean there's a chance of asexual reproduction?" He nodded.

"It's common." He noted, "But only with choice."

"That's cool."

"We often choose one of the partners to keep the young."

"You can choose?" He nodded.

"Much like that seahorse, men have brood sacs for gestation."

I was stumped. I hadn't expected such a difference between us. Although, that being said, it's not like I couldn't experience it - my quirk is Siren, after all. It's entirely based on the creatures, so it's possible I experience the same phenomena.

All in all I didn't know.

Regardless it was getting dark and I knew I needed to leave soon, sadly. Todoroki picked up on this disappointment quickly.

"You could stay." He suggested. I blinked, looking over at him with surprise.

"Aren't you going back to your pod?" I fretted, "Won't they be worried about you?" He shook his head.

"I said I was going away on a trip for a few days. My friends are covering me." He admitted casually, making me nod.

'I mean he's not wrong…'

"Do you want me to stay?"

"Yes." He answered quickly and unashamedly. I felt my body flush at his strong gaze and smiled.

"Okay."

One night turned into two and then three. Todoroki and I got to know one another more, learning about each other's lives. He promised he'd take me to the society he lived in some time soon and I promised to do the same for him when he informed me that he could shapeshift.

I was excited. However, when I woke up the next morning I found myself panicking.

Todoroki was gone.

"Sho?" I begged, hairs on the back of my neck standing on end as I searched the cove for any signs of his familiar red and white colouring.

Nada.

"Shoto?" I tried louder, jumping into the water to look around. When I saw I was alone, bar the mirage of fish, I started to panic.

This was the first time Todoroki had been away from me whilst I was awake. Sure he'd gone out to get food for us both, but I usually tagged along.

This was unusual.

Anxious clicking sounded from me as I tried to figure out what to do.

'Stay calm…'

I went back to the dry area and played with my hair as I contemplated what to do. I thought back to the night before to see if there was anything to indicate where he was going but failed to identify anything.

I felt alone and scared. So as a self soothing mechanism I began to sing to myself.

Todoroki came back to a humm reverberating around the cave and immediately panicked that another Siren had found me. However, he was overcome with relief when his head popped up into the dry area and he saw me combing my hair and singing to myself.

"You sound beautiful."

I screamed, not expecting any words as Todoroki successfully scared the shit out of me. That made him jump as I jumped back before I sighed with relief.

"You scared me, Sho!" I pouted, turning towards him.

"Sorry, Love." He apologised with a wry smile as I glared at him.

'She was anxious for me.' Todoroki trilled, 'She missed me.'

"Where were you?" I begged, coming forward slightly as Todoroki jumped up and onto the dry area effortlessly, pulling fish and oysters up with him. He gave a small smile.

"Breakfast." He chirped, passing me a fish. I took it, gratefully before tucking in, grateful that my stomach was capable of digesting raw fish and bones. So I crunched on the fish greedily as Todoroki watched me with an amused smile. I frowned at him.

"What?"

"Hungry?" I stuck my tongue out at him, earning a chuckle.

"It's tasty. What fish is this?" I begged curiously as I used my claw to remove pieces of bone and fish flesh from my sharpened teeth.

"Pollack." he noted, discarding the carcass back into the water for the smaller fish to eat. I hummed.

"I like pollack apparently." I mused, chucking the carcass back into the water as Todoroki had done. He offered me more, which I took greedily before they met the same fate.

Todoroki’s tail slapped against the ground as he ate. It didn’t take much to realise that he was anxious, but what about I wasn’t sure. However it wouldn’t be long before he scooted over and held an oyster on his lap, making me frown.

“What’s that?” Todoroki smiled.

“It’s for you.” I blinked up at him, confused as he passed the animal to me.

“To… eat?” I begged, “I’m quite full. I’d have eaten less if I’d known.” Todoroki chuckled at this and shook his head.

“No. Open it.”

I shrugged and did as requested. Much to my surprise there was a huge, orange melo melo pearl in the middle of several smaller oyster and mollock ones. The only one that was a perfect sphere was the large one in the centre. If I put my index finger and thumb together it would just about cover the size of the pearl. I gaped in shock at the beauty of the items before turning to Todoroki.

“Was this why you were gone for so long?” he nodded.

“It needed to be perfect.” he smiled.

“Oh, Sho…!” I chirped, pulling him into a tight hug and kissing him on the cheek.

Todoroki was elated. Not only had you accepted his gift, but you kissed him. This was ideal.

“What did you want to do today?” I begged leaning back. However I noticed the loving look that Todoroki was giving me and smiled, “You okay there, Sho?”

“Yes. And I have an idea.” he nodded, “Follow me.” he beamed, jumping into the water. I placed the oyster down where it’d be safe before jumping into the water and transforming. Todoroki waited for me and watched as I transformed with the same fascination he had the first time around.

This time, he wanted to satiate his curiosity as he came over and got close to me.

He felt along my leg-tails gently before moving to my main tail with curiosity. He left no area untouched as he glided his pads across my body, squeezing when he reached my ass, making me gasp.

I clenched my thighs in response but thought little of it; it's not like he knows what he's doing is a turn on. It's not like he realises the significance of that area… right?

Well he didn't, until he smelt the arousal that began to pool.

With a smirk, Todoroki leaned his back against my own before palming my ass and giving it a gentle squeeze.

“Sho-”

Smack!

I yelped in surprise as Todoroki slapped my ass before pulling me back close to him by the hip.

“Shoto!” I flushed as he chuckled into my ear.

“What is it, Love?” he begged innocently. I wiggled, causing my ass to brush up against his crotch and forcing a moan out of him. I ignored it and turned around in his grasp, bringing us face to face. He had a gentle dusting on his cheeks.

“That’s my ass you just slapped.” I pouted up at him. Todoroki smirked down at me.

“Yes.” he nodded, “I noticed.”

I wasn’t sure what to say to that. So I did the only thing I could think of.

I slapped his ass back.

Todoroki immediately yelped, making me laugh.

“Exactly!”

The next thing I knew Todoroki was wrestling with me and I ended up on the bed of the cave, laughing and shrieking as he tickled my sensitive sides mercilessly.

"S-Shoto!" I giggled, "S-stop! You w-win!"

"What was that, Love?" He begged, mockingly, "You want me to tickle you harder?"

"N-no!" I wheezed as he upped his cruel pursuit, “S-sho…!”

“Sounds like you’re having fun.” he smirked, as I flailed, trying to get away from him. It wasn’t working well. However he eventually halted his attack when I stopped trying to speak as I laughed.

“Better?” he dared to beg with a smile, as though he hadn’t been the cause. I shoved him roughly with a smirk.

“No thanks to you!” I whined, earning a small chuckle.

Silence fell over us as Todoroki stared down at me with a fond gaze, making me tilt my head at him. He seemed to be in thought, looking down at my tail.

“Can I see your legs?” he begged after a while, making me tilt my head again.

“What, like my human legs?” I begged, earning a nod. I shrugged and motioned for him to follow me as I led us back to the cove that was out of the water.

Jumping up I let my tails recede as my body turned back to normal. Todoroki with a sheer curiosity and focus so strong you’d think he was studying me, gently grasped my legs, fingers trailing as the scales vanished and soft, plump skin replaced them. Only when all the fins had vanished did he start to examine the limbs themselves, starting with my feet.

Rough fingers padded over my toes with a gentleness I wasn’t aware he had before they eventually played with my ankle, following the movement the joint made. From there he traced up my calves and did the same motions with my knee joint. His fingers continued to trail higher and higher until they reached my thighs.

It felt incredibly intimate, having the man’s hands all over my legs. The way his scales caught on the little hairs on my skin felt oddly nice.

“Have you seen legs before?” I begged, earning a shake of the head.

“No, not up close. Always been curious.” he murmured, focus completely on the task at hand, tracing his hands up my thighs and gripping them.

I felt myself flush at the contact, not expecting him to grab and gently claw at my skin.

I’d be lying to say it wasn’t a turn on and unbeknownst to me, Todoroki could smell it. He’d caught a whiff of it when I was in the water being touched by him earlier, but his sense of smell was even better and adapted to the air, which meant the smell came off me in waves that pleased him and had him churring. It was a noise I didn’t recognise, but I could tell it was good even if I was unaware of the cause.

When his hands dared to go higher, towards the sweet, sumptuous scent, however, I squealed and flinched away, causing him to jump back.

“What?” he yelled back, “Did I hurt you?” he begged, worried. However I paused, cheeks a deep red as I pulled my legs to me. I slowly uncurled and shook my head, not looking at him in the eye as I attempted to process how to explain it to him.

“That’s…” I bit my lip, “That’s where my reproductive organs are.”

Todoroki slowly came back close, relaxing at the explanation, even chuckling gently at my reaction. However, to my surprise he slotted himself between my legs and gripped at my thighs again as he stabilised himself.

“Can I see?” he begged curiously, tilting his head to the side.

I blinked up at him, feeling my cheeks heat up all over again.

‘I really shouldn’t…’ I clenched, ‘He’s a Siren. This is wrong, right?’

“You know,” Todoroki began with a small smirk, “only my mate is supposed to look and touch my tail.”

“Really?” I begged, surprised, earning a nod.

‘I shouldn’t…’ I bit my lip as I thought about it a bit longer. Todoroki, at my uncertainty nuzzled my face and neck, trilling when I nuzzled back, ‘Ah fuck it. I like him.’

I carefully cupped his cheek before kissing him on the nose. Todoroki, though surprised, only trilled more as he leaned in for something more.

I moaned into the kiss as he pulled me into him, one hand going to the back of my head and the other to my hip. I immediately lost my own in his hair as I made out with him, his saliva tasting of the sea and fish, which was strangely pleasant on my tongue.

I felt him groan into the kiss when my hips pressed against him, his hand on my hip encouraging me to grind on him. My own thighs clenched around him as I did, especially when something pressed back, eliciting a moan from both of us.

‘Is that his…?’

I didn’t have much time to find out as Todoroki pulled back and yanked at my bikini shorts. I giggled a bit at his eagerness before leaning back, letting him remove them. I eyed him from my prone position as his nostrils flared and fingers traced along my thighs and up towards my groin. His gaze was entirely engulfed by my nether regions as he gently felt along my slit, settling on my clit when I jumped at the contact, padding his thumb in small circles as I began to moan.

“Shoto…” I groaned as he lent forward, eyes watching me closely as he gave a tentative lick, which made me gasp out. Smirking at this, his gaze never left mine as he replaced his thumb with his mouth, sucking at my clit greedily and taking in the taste with his tongue, letting out a guttural groan.

My gummy, aching cunt clenched around his tongue each time he entered me before he settled back on my clit. Bringing his fingers up he teased my entrance before plunging them in, curling them to reach that nice spongy area that had me seeing stars.

“S-Shoto!” I howled, “I-I’m close…!”

At my words, Todoroki sped up his ministrations, trilling when I finally came on his tongue. He slurped at my pussy with vigour until he was satisfied he’d tasted every last drop. Removing his fingers he gently licked at his coated claws before pulling himself to me, climbing on top and making me squeak as he chuckled.

“You taste beautiful, Love.” he purred, nipping at my neck gently as I tangled my hands in his hair again.

“S-Shoto.” I hummed, pulling him in for a kiss as he ground down into my core, forcing more moans from me.

Todoroki went back to my neck, nipping and sucking, leaving little cuts and bruises in his wake. I didn’t mind as I nuzzled and kissed the side of his neck lovingly. However when he bit down on my neck I yelped.

“Sho-!”

“It’s okay, Love.” he purred, licking at the wound as I felt his venom hit me, making me feel dazed for a moment before I suddenly felt like my nerves were heightened. Every nip, lick, kiss and suck felt stronger than I’d expected, eliciting many moans from me as he worked down my body before pulling at my bikini top with a snarl when he couldn’t untie the knot.

Sitting up slightly I pulled it over me and discarded it and Todoroki immediately jumped back on me, mouthing at my nipple whilst playing with the other between his fingers. I began to pant at the sensation as he continued to grind into me, catching my clit on his scales.

“Ahh…!” I whined when I felt something catch at my entrance, “Sho…!”

Todoroki grunted at the sensation as his dick moved and wiggled slightly to gather slick, making me realise it was prehensile. However, I felt confused at feeling two separate objects.

When I looked down I realised he has a hemipenis or a clasper.

‘So it’s prehensile and there’s two of them?’ I baulked, ‘Is this why he bit me? So I wouldn’t feel any pain?’

I wasn’t entirely sure, but I didn’t have time or the mentality to ask as he slowly slipped inside of me, the bulbous heads slipping in against my slick with ease. I gasped, breathing out an airy moan as his cocks wiggled their way into me, filling me up to the brim and pushing against my cervix.

Todoroki held his breath as he took in the sensation of my warm, gummy walls around him, surprised by the warmth that radiated from the moist cavern. He was sure that this was true bliss as he dared to sheath himself in, down to the hilt before letting out a small grunt. Pulling back gently, he thrusted himself in, watching as my breasts bounced and I gasped out, pink flushing my cheeks.

It really was a sight to behold in his eyes. His mate all flustered and choking back moans as he bounced me on his cock, wet slapping reverberating off the cave walls.

“S-Shoto!” I squealed as he hit my g-spot, “T-There!”

As if on a mission, Todoroki aimed his cocks directly for that lovely spongy area, hitting it at a rapid pace as he sped up. I was surely seeing stars as I choked out more moans and groans.

Todoroki, as he pulled back and slammed into me again, pulled my legs over his shoulders and put me in a mating press, reaching slightly further in me than he was before. He groaned, the new position squeezing him in tightly. When he looked down he could just about see himself pushing against my insides from the outside of my stomach.

Putting his hand there, he pressed slightly, causing me to gasp.

“You feel that, Love?” he panted, “That’s me in there. Pushing against you.”

I nodded, fervently, uttering his name as I began to get close, pussy fluttering around him and milking him for all it’s worth.

“P-please, Shoto!” I begged, “I-I’m so close!”

“Cum for me, Love…!” he demanded, before he latched onto my shoulder and continued to mark me, muttering for me to cum for him in my ears. And before long I was, calling out his name loudly.

“Shoto!” I howled, cunt clenching around him. He grunted, snarling as the tightness made his hips stutter. Basking in the new sensation, he continued to pound into me through my orgasm before he bit down on my neck again, cumming deeply as something pushed against and through my cervix, making me whine.

“S-Shoto…?” I begged, confused as I began to feel full. However Todoroki churred and trilled at my neck, rubbing my belly lovingly.

“Just my eggs, Love.” he nuzzled as my belly began to swell with his first spray, “Eggs and sperm. Our younglings.”

I didn’t fully process his words as I grew tired, a side effect of his venom I guessed. But I didn’t mind as I nuzzled him back. Only did he exit when he felt his egg sac fully deplete and immediately he pulled me to him and snuggled with me on the moss bed below us.

“Get some rest.” he whispered, “You’ll need it.” I frowned gently.

“Why?” I muttered, snuggling close to him. Todoroki chuckled.

“Don’t think I’m done with you.” he teased, nipping at my ear and making me giggle.

I didn’t mind the idea of round two with the Siren and fell into a blissful sleep with him guarding me the entire time.
