right, sex chapter. this is happening now.

for those wondering, i needed a break. i've also decided to start working on a couple other fics. one's a one shot for this fandom and might be out soon. the other is a multi chapter for a different fandom, and i have no idea when i'm going to post it.

i can't tell you guys enough how happy about all the comments, follows, and favourites make me. thank you, it means a lot.


You know, when I finally left home, leaving my mother weeping with hope and loneliness at the door, I didn't know what to expect. I mean, sure, I had a lot of hopes in life. I wanted to get a stable job, do well at said job, and eventually settle down and start a family. I'm not sure how many kids I wanted, or even if a plain faced, scatterbrained man like me could even properly court a woman, but I definitely wanted them. I still do in fact, almost desperately now.

What I didn't expect, was to almost drown on a business trip, have my body forcefully change into that of another species, and then have all of my morals and spiritual beliefs put into question. It's the best I can do not to just break down or lash out. Not that I really had the time to do so, not after having so many startling revelations in a row.

First I was reeling from coming into contact with a friendly mer. Then it was finding out that he was trying to seduce me, and that he did, in fact, "speak" a language of his own. And before I could start unraveling the knots of the conundrum of my own feelings and sexuality, I find out that I'm going through the mer equivalent of spawning season.

The only reason I know of such a thing, is because Shinsou told me about it a few days before I went overboard. I had asked him why the fish I was eating had a bunch of salty beads in its stomach, and he explained that they were eggs and that that species of fish was likely close to spawning. I felt somewhat horrified that I had been eating another creature's unborn offspring, but he assured me that they weren't fertilized since they were still within the creatures' womb. Judging by my own anatomy, I think the eggs are fertilized and possibly carried while still in my body. Which means sex. Honest to god, physical sex.

I sigh and close my eyes, letting the gentle current drift around me and cool my heated flesh. I let the sensations of my fluttering hair and the light of the shining sun fade into the background. I take a deep breath, and place my hand over my slightly swollen belly. I gently poke and prod, feeling out the eggs that are growing inside me. Eggs, dear God, eggs. If I hadn't already found out that I still had a penis, then I'd be freaking out about my gender all over again. While this does bring up many questions about mer reproduction and how genders are determined and why, I can't seem to care right now.

This may be due to the fever that my new hormones have brought about, but the only thing I can really think about, without getting distracted, is what I'm going to do about this. I slowly open my eyes again, and stare at the rippling surface. For a reason that can only be explained away as instinct, I felt the need to swim near the surface and float belly up in a mild current. It's likely related to the fever I woke up with this morning, but I don't really feel like looking into it too far right now. The water feels nice on my skin, and it's giving me a chance to calm down enough to decide whether or not I want to do something with my newfound fertility.

I do want kids, I always have, but do I want them now? Do I want to have them with this body, birthing them myself from my own loins? Do I even want kids that aren't human? I only had a vague idea on child rearing before, but what would I even do with mer kids? I barely know how to take care of myself right now, how could I take care of another? What can I do? I can't do this on my own.

"Izuku?"

But I don't have to do this alone, do I?

My hooded eyes drift over to see Shouto swimming up on my left side, concern etched onto his face. His eyes flit over my prone form, inhales none too subtly, and starts to look furtively around. It seems he hasn't got any new wounds today.

It wouldn't be so bad, if I did this with him. He's so kind and considerate, and he's never hurt me so I don't think losing my virginity to him would be that bad. He's also proven himself to be a good caretaker already, so he'll be able to help me raise any little ones we have. He'd probably know more about how mers are raised than me anyway.

Shouto's gaze turns back on me, looking a tad frustrated. His hands twitch towards me, but he mostly keeps them at his sides. His mouth twists into a frown, and he speaks again.

"Izuku? I… touch? Ok? Shou- I want…"

His hand gestures are a bit erratic, but are once again saying more than his stumbling words. I don't truly understand what they mean, but I can guess. Ok… let's do this. It's now or never, right? Shouto stops his gesturing, having given up on verbal communication after not finding the right words, when I reach up and grab one of his hands. I look directly into his eyes and nod once.

"Ok. Yes. I want it too."

Shouto seems to hold his breath for a moment, before nodding in return. He gently tugs me close, and tucks me into his arms. He nuzzles his face into my hair, and licks a stripe along my right temple. A low rumble sounds from Shouto's chest, and he squeezes me just a bit tighter. I mewl softly in response, and squirm in discomfort. My body's heating up again, and my slit is starting to tingle.

Taking the hint, Shouto starts swimming down towards the seabed. I manage to wind my arms around his neck, but otherwise stay still in his secure embrace. As I absently glance around, I notice that he's taking me in the direction of my cave. That's good, I kind of don't want my first time to be out in the open, even if there's no one around.

I let out a breath, and close my eyes. I let my head rest on Shouto's shoulder, and enjoy the cool water running over my flesh as I relax. The light soon disappears as Shouto maneuvers me over the threshold, and into my living room.

I finally open my eyes when my back hits cloth, as Shouto gently lays me down on my nest. When he lets go, I wiggle around a bit to get comfortable, while Shouto goes off into the living room and does something. Once I get settled and comfortable, I run a hand down my egg swollen belly to sooth my building nerves.

Before I can linger on the thought of sex for too long, Shouto swims happily back into the room. His eyes roam slowly over me, and take on a hungry sheen. My breath hitches at the sight, and an excited shudder runs down my spine when Shouto lays a hand on the base of my tail. He slowly trails it up along the scales, and pauses once he reaches the swollen part. I'm not sure how many eggs a mer can carry at once, but there must be a lot to have swelling from just below my navel, to a few centimetres below my anal slit.

A low, chittering growl fills the room, and Shouto leans down to gently nibble along the raised scales. My breath hitches again at the action, and I can feel my channel tingle and clench in anticipation. My breathing turns into huffs and pants as his mouth draws ever closer to my leaking slit. Just before his sinful mouth reaches it, Shouto suddenly moves up and away, causing me to let out a whine.

Shouto lets out a coo, and gives me a gentle smile as he lays a soothing hand over my cheek. He settles his body back down over top mine, which makes my face heat up with a fiery blush. Oh god! He's… he's on top of me! With a startled squeak, I avert my face, covering it awkwardly with my arms, and start to squirm away from the large mer.

I hear a grunt from above me, and suddenly Shouto is dropping his weight down on me, effectively pinning me down with his long tail. I never really thought about it before, but Shouto is really heavy. Must be all the muscle. With my movement, and thus my escape, halted, Shouto grabs my arms and pulls them away from my burning face.

There's a slight frown etched onto his face, and he rests his forehead against mine. He rubs circles into the palms of my hands with his thumbs, trying to calm me down. His brows furrow in concern, and he tilts his head slightly to the side, giving me a better view of the red scales around his eye.

"Izuku ok? I… more?"

Oh god, why is he asking again? I take in a deep breath, closing my eyes as I hold it for a moment before releasing it. I need to calm down. I wanted this, remember? I'm freaking him out, and am going to ruin it if I don't get a grip on my emotions. I take a few more breaths, and finally open my eyes to gaze into Shouto's kind, patient ones.

I tug my hands out of his, and timidly wrap my arms around his shoulders. When he doesn't do anything beyond gaining a curious glint to his eye, I tentatively pull his head down and place a chaste kiss to his closed lips. Huh, they're pretty smooth. Just like the rest of his skin.

After a moment or two of no reaction, I shyly lean back into my nest. Shouto tilts his head further to the side, an innocent look on his face. I guess mers don't normally kiss to show affection. My face heats up again and I cover it again with my hands. Ooh, I did something so shameful! What does he think of me now!? A stressed noise comes from the mer above me.

"Izuku!? What Wrong? No touch? No Want?"

I peek up at the now flustered mer through my webbed fingers, and look into his panicked eyes. I squeak and shake my head, cupping his face in my hands. Right, time to get a move on. I think we've waited enough. I'll just get more shy as time goes on, so I just need to give him permission and let him do his thing. At least I won't have to do much for this, I don't think I could handle it just yet if I had so much control.

"It's ok. You can do what you want. I want you too."

He still looks at me with trepidation, so I make my final bold move, and grab one of his hands. I slowly lead it down my waist and rest his fingers over my necklace, which is laying precariously over my slit. I then look back into his eyes and give a confident nod.

"Yes. It's ok."

The determined look slides back onto his face, and he leans down to nuzzle the side of my face. My eye closes has his red hair tickles my nose, and I feel his fingers flip the necklace up onto my swollen belly. With the object now out of the way, I feel his tail shift around again as he positions himself. He's still pinning me down, but his pelvis is now perfectly aligned over my slit. He deftly dips the tip of his thumb into my hole, and pulls it to the side as he presses his groin flush with mine. Which, I suppose, is to help his member enter me.

Right, it's go time I guess. Will it hurt? He can't be that big right? I mean, mine isn't, and his is probably the same size, right? I haven't seen it, and it's not really on display right now, but that just means he hasn't brought it out yet right? He'll just ease it out and-

"Ah!"

"Izuku?"

I cry out in surprise as something suddenly shoots out and impales me, filling and stretching me to the brim. He's not small! Not small at all! I let out a pained whimper, and Shouto starts fretting and cooing over me, trying to get me to calm down. He licks and caresses my face, nibbling my freckles as I breath through the burning pain.

Jeeze, just how big is he? My toy never got me feeling this full, and I feel like he's pretty deep in there. I shift a bit, as much as his weight will allow, and I gasp as I feel something tickle me deep inside. It feels like the sensation is coming from my belly. Shouto grunts from the motion, and seems to take this as a signal to continue.

He wraps his arms around my waist, taking care to rub his wrists along my torso, before squishing me into his. Anticipating his next actions, I tightly wrap my arms around his chest and bury my face in between his pecks. With a snapping motion, Shouto pulls out a bit and ruts back in. I gasp from the rough motions, but it already feels way better than before. His member is blessedly smooth, and the initial burn was just from the sudden stretch of an underused organ, so he's already sliding in and out easily.

My gasping moans soon turn to squeals as the pressure of his thrusts starts stimulating the top of my canal, and my penis starts to react accordingly. I feel it slip out of it's sheath, and the stimulation doubles as it rubs and grinds against his waist. Suddenly feeling breathless, I crane my head back into free water, and gasp as my core starts to pulse and tighten.

"Shouto! I-I! A-ah-ahhhh!"

I cry out as I release, and Shouto growls harshly in response. His claws dig into my back, and the angle of his thrusts change. I whimper from the over-stimulation, and he grinds his pelvis into mine as he bottoms out again and again. That tickling sensation deep inside of me suddenly changes, and I feel his member slip impossibly deeper, passed some kind of barrier.

As soon as this happens, Shouto seems to freeze, and I yelp as stinging pain rips through me, just under my rim. It feels like needles or barbs just dug into my flesh, as Shouto unloads his seed deep inside me. The suddenness of both sensations, rips a final orgasm from me, and I feel my walls clamp down along his ridiculous length. A low, soothing rumble sounds out, and Shouto goes back to nuzzling and caressing my hair and face. The faint scent of blood wafts up to me, but I choose to ignore it. I just lost my virginity after all. It's probably normal.

Once my body calms down, I start feeling exhausted. That… was really good. It had a shaky start, but was amazing in the end. A responding purr vibrates trough my chest, and I snuggle into Shouto the best I can. If I wasn't so tired, I'd probably be more embarrassed about the fact that he seems to be stuck inside me. Maybe I'm a little concerned, but I'm ultimately too tired to worry about it right now. If it wasn't normal, Shouto probably wouldn't be this relaxed.

fun fact, all fish don't spawn at once. and a lot of them spawn multiple times a year. different things can trigger it, like temp, pH levels, even the availability of food. so i decided to make my own system up for mers. i will bring it up in the story later.

right, i have a question. toga, bakugou, or monoma. i'm not going to give context because that would be a spoiler and may introduce undue bias. just pick a name and shout it in the comments.
