It was supposed to be a nice break. Easy, relaxing, just a good way for everyone to unwind and take a breather from the stress of daily life. Well… some people just got a bit more unwound than others.
If you ask Jaehyun, he’s innocent. He didn’t mean to nudge that little pile of what he thought was weird kelp just a bit too hard. He didn’t even really have time to respond when a thick tendril snaked out from it and encircled his ankle, pulling him down to the ground to drag him farther along the beach. It’s not like it would have even helped; it’s early morning, he’d been pretty far away from the beach house they’d all been staying at, and there’s not really anyone else out here.
Either way, he’s hidden in some rocky cave near the water now, away from any prying eyes that might come from the landside, but in full view of anyone — or any thing that might approach from the ocean, something that sends a sick thrill through him, even as he struggles halfheartedly against the tentacles holding him in place against the wall, a few each around his wrists and ankles. He notes distantly that one of his sandals is missing, probably lost on the beach earlier.
“Look, I don’t — I dunno if you can understand me, but, if you can, what do you -“ His breath hitches as another tentacle slithers up one leg, teasing at the hem of his shorts. “What do you want with me?”
He’s honestly not sure what he expected as an answer, but the brief flash in his mind of what he assumes is a telepathic image of himself full and dripping with something disconcertingly come-like was not very high on the list.
“U-um. Okay, I’m not, uh, very sure about that,” he replies out loud, only for the tentacle sliding up his leg to coil around his thigh in a way he could only describe as possessive. That definitely makes him feel.. something.
“Hey, can we, like, back up a bit, I’m feeling a little —“ He gets cut off with a yelp as a tentacle shoves into his open mouth, and he starts wriggling in earnest against his bonds in response, trying to shout around the intrusion. When he hears a sound from the water at the mouth of the cave, he snaps to attention, watching as something - someone? - comes to the surface and hauls itself up onto the rock.
“Changmin? ” He tries to say, but it comes out muffled and mangled, for obvious reasons. Changmin smiles brightly when he sees Jaehyun, picking up the blob the tentacles are emanating from and cradling it gently, petting over its surface.
“Hyung!” Changmin says in reply, laughing a little. “Didn’t expect to see you here.” The tentacle in Jaehyun’s mouth eases out, and Jaehyun grimaces at the way the slime on it connects in a string to his mouth until it pulls away far enough.
“Wh-what do you mean —“ He ends up cutting himself off with a cough, some of the slime still lingering in his mouth. “God, shit. What do you mean, ‘didn’t expect to see me’?” Changmin doesn’t answer for a moment, too focused on the thing he’s holding, and he even gives it a little kiss — god, what the fuck, Jaehyun thinks — before he looks back to Jaehyun.
“Well, I mean, I expected to find someone when I got here, but not you . I mean that very nicely.” Jaehyun gapes at him, still wildly confused.
“Lemme try again. Why were you expecting someone here?” Changmin doesn’t answer him again, although this time, it’s with purpose. He lifts the blob up to eye level, examining it for a moment, and then brings it close to his chest, where it sort of.. latches on and crawls over his shoulder to his back. Jaehyun watches on in a kind of disgusted amazement as Changmin shudders, eyes slipping shut, rolling his shoulders and neck. The tentacles seem to be sprouting from Changmin’s back now, like an awful bastardization of an angel’s wings, and his skin has taken on a bluish pallor, a slight sheen coating him as well. When Changmin looks at him, his pupils have a more rectangular shape to them, the irises taking up the rest of his visible eye, and when he smiles, his teeth have a razor sharp edge.
It should be gross, really, and it kind of is, but Jaehyun can’t deny feeling a stirring in his gut as he takes in the sight of this new, transformed Changmin. That should be worrying, why isn’t that worrying? Maybe he hit his head on a rock when he was being dragged down the beach.
“Why do you think, silly? It’s that time of the year again, I have to stick my eggs somewhere, don’t I?” Changmin says this as if it’s the most logical thing in the world, like Jaehyun asked a dumb question, which feels entirely unfair. Speaking of —
“Your fucking what? ” Jaehyun asks, bewildered, not wanting to accept the obvious answer staring him right in the face. Instead of answering, one of Changmin’s tentacles finds its way to Jaehyun’s mouth again, and he doesn’t struggle this time when it pushes in slowly, the tip bumping the back of his throat. Well, he doesn’t struggle too much, at least. There’s still that initial instinct to fight it, but then it starts secreting something in his mouth, sweet and salty and a little bitter, and Jaehyun feels his body relax, even as his brain is still going a mile a minute.
Changmin walks up to him then and caresses Jaehyun’s cheek, thumbing at where his lips are stretched around the rather sizable tentacle.
“I love you, hyung, but you talk a lot. Ask too many questions when the answer is right here.” Changmin’s free hand traces down Jaehyun’s side, over his t-shirt, and then trails back up underneath the fabric to rub across his stomach. Jaehyun cringes at the slick feeling of it, but appreciates how it cools his overheated skin. He whimpers softly as Changmin proceeds to rub his stomach a little more, touch firm and purposeful.
“Right here,” he repeats, squeezing Jaehyun’s stomach briefly, grinning sharp and cold, before stepping back and letting his tentacles do the work of getting Jaehyun ready. One curls around his waist to hold him there against the wall while more still work off his clothes, surprisingly more deft than Jaehyun was expecting. Sure, his clothes are going to be covered in whatever weird octo-slime Changmin has going on, but at least nothing is ripped. He wonders distantly what the washing procedure is like for getting this shit out of clothes, if there even is one. This doesn’t seem like it would be a regular occasion in enough people’s lives to warrant a WikiHow article about it.
Jaehyun dials back into the situation at hand once the tentacles return to his wrists and ankles, in addition to the one still around his waist. He makes a little noise around the tentacle in his mouth as Changmin stands from where he was perched on a small section of rock, and makes it again when Changmin starts touching him, hand moving practiced and methodical on his dick.
“So here’s what’s going to happen, hyung,” Changmin starts, and his voice leaves no room for argument - not that Jaehyun wants to argue, or even that he would, with or without the help of Changmin’s aphrodisiacs. “I’m going to get you off, once, maybe two times, get you nice and brainless with pleasure. While that’s happening, I’m gonna start loosening you up so you can get bred all full. Doesn’t that sound nice?” Jaehyun nods automatically, not even sure fully what he’s agreeing to at first until it really sinks in.
“Wait — ” He tries to speak around the tentacle in his mouth, and Changmin’s only response is to slide it just a little further down his throat, effectively silencing him.
“Don’t worry, hyung,” Changmin says with a sweet smile, teeth glinting in the low light of the cave. “It won’t even hurt.”
*****
Hurt, Jaehyun finds out, is a relative term. He’d thought Changmin was out of his mind when he’d said it wasn’t going to hurt. Having tentacles shoved in him when he’s never even thought about bottoming before, and being filled with — ugh. Point is, he thought it would hurt, badly, and that Changmin was just fucking with him so he wouldn’t freak out.
Questionable timing on attempted soothing of fear, Changmin.
But it doesn’t hurt. In fact, he barely notices it at first, too distracted as he’s coming down from the first orgasm Changmin had stroked out of him, smooth and easy. He’s panting around the tentacle in his mouth, even letting out a little moan when it starts moving, gently fucking into his throat. Changmin is just watching him with a cool gaze, emotions unreadable. It’s only as the hand on his dick pushes the lingering pleasure into oversensitivity that Jaehyun can feel it — a long, somewhat slender tentacle buried inside him, getting him used to the feeling. It’s weird, to say the least, and he squirms, making a small noise of discomfort. Changmin just keeps watching, eyes calculating.
“How does it feel, hyung?” The tentacle in Jaehyun’s mouth eases out, and he coughs, taking a few deep breaths before responding.
“A-ah, it’s - it’s weird. I dunno,” he replies, voice a little rough. It looks like Changmin considers that for a moment before the tentacle inside Jaehyun pulls out, replaced by one a little smaller.
“There. Better? We’re on a schedule, so I want to make this quick.” Jaehyun’s head is still a little fuzzy from his previous orgasm, and from — wait. Changmin has his arms crossed now, so what-?
Oh. There’s a tentacle jacking him off now, because of course there is. Just how many of these does Changmin have? It seems like a lot more than the standard eight of a normal octopus, although, perhaps the standard of what’s normal doesn’t exactly apply here. Wait, Changmin asked him a question.
“Huh?” Jaehyun asks, having forgotten what was originally asked of him. Changmin scoffs, clearly trying not to roll his eyes, but he still looks fond, which is very strange with the way he looks currently.
“I asked, is that better? The one inside you?” Jaehyun has to take a moment before he can respond, trying to think about what he feels like.
“Um, I think so?” Changmin sighs and rubs his temples, stepping forward and crouching next to Jaehyun. He moves Jaehyun away from the wall slightly, running a hand over his ass and giving a little teasing smack, smiling at his yelp of surprise, before prodding at his hole with the tips of his fingers. Jaehyun squirms a little, and Changmin can tell he’s starting to get aroused again, breathing heavily, cheeks and chest flushed. Changmin pulls the tentacle out of Jaehyun and replaces it with two fingers, something Jaehyun seems very receptive to, if his responding moan and full body shiver is any indication.
“I see you like that,” Changmin remarks with a little laugh, and Jaehyun just nods with a whine, twisting his head to look down at Changmin.
“Your, ah, your hands are a lot warmer,” Jaehyun replies, biting his lip. Changmin just gives a little hum, adding in another finger and continuing to fuck them into Jaehyun, pulling another shaky moan from him. Eventually, Changmin gets tired of crouching and stands, pulling away from Jaehyun to stretch. Jaehyun whines at the loss of his fingers, but he quickly becomes more concerned with the tentacles holding him shifting, the ones on his wrists sliding down his arms to loop around his chest and shoulders, and the ones around his ankles lifting him off the floor, holding his legs up and apart.
Changmin steps between Jaehyun’s spread legs and runs his hands along his inner thighs, over his stomach.
“So pretty,” he murmurs appreciatively, squeezing the flesh beneath his hands. “Gonna look so good all filled up.” Jaehyun whines in response, sucking in a breath when Changmin shoves his fingers back inside.
“What do you think, hyung? Feel ready for it?” It’s a check-in, but also feels a little rhetorical. Jaehyun is going to end up taking whatever Changmin gives him regardless of if he’s ready or not, and Jaehyun might have to examine later why the thought of that makes his dick twitch. He nods anyway, the stretch around Changmin’s fingers barely noticeable. Changmin keeps fingering him for a little longer, enjoying his reactions, before pulling his hand away, wiping it on Jaehyun’s thigh. Jaehyun doesn’t have much time to be offended as one tentacle slides home in his mouth again and another prods at his ass before pushing in, the tip of it feeling much different from the other ones he’s had in there. Where the others had tapered off into a dull point, this one is more substantial, ending in more of a tube shape.
It’s a bit of a strange feeling, but the tentacle in his mouth is doing wonders to alleviate any of his tension, secreting that sweet-salty fluid again and making him feel relaxed and at ease. Changmin smiles, rubbing Jaehyun’s thigh again.
“Good boy, hyung. This’ll all be over soon.” Jaehyun whines, the tentacle inside him starting to pulsate, for lack of a better word. His eyes widen in a slight bit of alarm before he feels… it. The first egg of many pushes into him, briefly stretching him to almost past his limit before it settles inside him. It’s a very, very weird sensation, but he figures he’ll have to get used to it pretty fast as he can already feel the next one pushing at his rim. If he’d had any ability earlier, he’d have asked just how many of these are going to have to go inside him, but there’s obviously no chance to right now.
Instead of worrying about that, he decides to focus on the feeling of the egg already inside of him. He’d guess it’s a little smaller than his fist, and feels kind of teardrop shaped. Now that it’s settled inside him, he's not necessarily opposed to it. The fullness and how he can feel its weight so clearly are a little disconcerting, but nothing he can’t handle. He hears a noise as the next egg pushes in, and looks up to see Changmin looking flushed, a bit winded. Jaehyun’s eyes widen and his dick jumps in the hold of the tentacle still stroking him. He moans softly, and the tentacle in his mouth pushes deeper, but now he welcomes it, eyes rolling back.
The second egg is fully seated inside him now, and Changmin leans in to grab onto Jaehyun’s thighs, panting a little, head hanging forward.
“Just - ngh, fuck - a few more,” Changmin says, breathless. “Doing — d-doing so well, hyung.” Jaehyun preens under the praise as much as he can, moaning deep in his chest when another egg pushes in, easier than the last, making him feel almost, almost uncomfortably full, like he feels after a good meal. Changmin is visibly trembling with the effort to stand, blunt nails digging into the meat of Jaehyun’s thighs. Two more eggs breach him, one after the other, and he groans at the feeling, starting to squirm from the unyielding pressure of being stuffed full combined with how he’s getting close to a second orgasm. Changmin shushes him gently, pulling out the tentacle in his mouth and tugging him forward into a surprisingly gentle kiss. Jaehyun makes a noise of surprise, followed by a little squeak when he feels Changmin’s teeth catch on his lip.
“Doing so well,” Changmin repeats, murmured against Jaehyun’s lips, and reaches down to wrap his hand around Jaehyun’s dick, moving in time with the tentacle still holding him. “Come on, one - a-ah, one more, one more and it's over.” Jaehyun nods a little, whimpering softly. So much is happening at once, he feels like he’s drowning in stimulation, but he loves it.
“Close,” he whines out, and Changmin nods in return, speeding up his hand and kissing down the side of Jaehyun’s neck, teeth scraping the skin. In the span of the next few seconds, many more things happen at once; the last egg slides inside Jaehyun, the easiest by far, Changmin nips just a little bit harder at Jaehyun’s skin than before, and his hand tightens its grip on his dick just the right amount, everything culminating in in him coming with a loud cry, his body shaking from the force of it. Changmin tenses against him with a low moan, and Jaehyun feels something warm and sticky dripping down his back, seemingly coming from the tentacle that had been in his mouth.
Jaehyun stares into space, breathing labored as he comes back into himself, and he feels himself being lowered to the ground, the all the tentacles that had been restraining him letting go and slithering away from him. He watches, blearily, as they retract back into Changmin’s body, making Changmin shudder. Once that’s over with, Changmin kneels next to Jaehyun and runs a hand over his stomach, pressing on the obvious bulge and pulling a disgruntled noise from Jaehyun, who bats his hand away.
“Doooon’t,” he whines, and Changmin laughs, giving Jaehyun’s tummy one little poke before going back to gently rubbing over his skin. He waits patiently for Jaehyun to regain some form of coherence, stroking his free hand over Jaehyun’s hair and face. Jaehyun blinks up at him after a long while, looking tired, but he’s at least lucid.
“There. That wasn’t so hard, was it?” Changmin asks, tone light. Jaehyun laughs, covering his eyes with one arm.
“Easy for you to say. You’re not the one who’s going to have to birth all these later.” Jaehyun looks playfully annoyed, but he sounds genuinely happy, like this all started to appeal to him by the end. Sure, it was awkward and uncomfortable at first, but he doesn't think he’s ever come that hard before in his life, so it’s safe to say it ended up being a good time for everyone involved, and he’s happy to help a friend in need. It’s then, however, that Changmin sucks in a breath through his teeth, and Jaehyun moves his arm down to look up at him again.
“... What was that for?” He asks, suddenly suspicious. Changmin looks almost apologetic as he pats Jaehyun’s stomach, and Jaehyun smacks his hand away again. “What was that for.” Changmin bites back a little smile.
“Really, hyung, it’s so cute that you’re that excited over it, endearing, even. But… I’m sorry to say, none of those were fertilized. I came before I could do it. So…” Jaehyun balks at this admission, any sliver of a moment he’d been having being utterly shattered.
“Wh- are you serious? Like, are you actually serious? All that and for — oh, you little asshole —” Jaehyun tries to push himself up to a seated position, but ultimately flops back down to the rock, wheezing. “I’m gonna fucking — hit you with a baseball bat, a baseball bat, or, or a phone book —” Changmin giggles, petting Jaehyun’s head, and he laughs again when Jaehyun tries to bite at him.
“Don’t worry, hyung. You’ll just have to stay like this for a few hours until they come out on their own.”
“A few WHAT? ”
