It was pure luck that when he sank into the dungeon’s lake, Laios saw the mouth of a tunnel and managed to haul himself into it and up, up into an open space. His head breaks the water’s surface—he’s come up in an air pocket, a cave with a shoreline.

A cave with an occupant, because the eerie, milky eyes of a kelpie are staring into his face.

Laios flounders, tripping backward and almost going under the water again in his panic. There’s a liquid noise, something quieter and softer than a splash. It’s in the water with him now. He imagines teeth meeting in his neck, at the front where the armor doesn’t protect, and takes in a gulp of water instead of air.

Something grabs him by the back of his neck, and pulls with a strength beyond the human.

Laios lands on the bank, spluttering and coughing out the lake water. He’s on his hands and knees, struggling to breathe, when a hand comes to rest on his back. At his side, the sword trembles.

Laios tries to rise, and crumples onto his side instead. From there, he has an excellent view of a woman watching him with the kelpie’s white eyes, nude but for the shape of a pelt—a horse-skin—pulled around her body.

“Oh, calm down,” she says, her voice slower and deeper than any woman he’s met before. “Only a desperate kelpie would eat an adventurer—and even if I were, I’d choose easier prey. I don’t fancy pulling you out of all that plate armor, like shelling a mimic.”

Laios splutters, though he’s not sure if it’s the water in his lungs or the naked—woman? kelpie?—in front of him. He thinks he can feel a blush rising in his cheeks.

“I won’t bite,” she says, a smirk swelling into a mischievous grin that shows the sharp points of her teeth. “Unless you want me to, that is.”

Now Laios knows he’s blushing furiously.

Her brows, green as her hair, lift slightly, and her lips part in something between surprise and amusement. “Well, look at that,” she says, “a tall-man who’s into monsters.”

“T-to be fair,” Laios finally manages to stammer, his voice rough from the water, “I’d prefer not to do it with your other shape.”

A pause. He thinks he’s offended her—

And then she laughs, a wild, sharp-edged sound almost like a horse’s cry, teeth flashing, and Laios swallows hard. The horse-skin has slipped a little, and he can see the shape of her breasts. He feels his face heat.

“Oh, tall-man,” she says at last, still half-laughing—and Laios loves the sound—and she meets his eyes again, “I almost wish it was my rut.”

Laios swallows again. He knows about kelpies, more than most adventurers, but not their reproductive habits. No one does. Kelpies are reclusive, rarely willing to take a human form at all, and most are dangerous.

Before he can stop himself, he asks, “What would you do…if it was?”

Those strange milky eyes widen, appraising him slowly. Her tongue darts out, flicking over her lips almost hungrily. Oddly, it doesn’t frighten Laios at all—which is perhaps a sign that he’s swallowed too much water.

“Well,” she says slowly, holding his eyes with her own, “that depends.”

“On?” Laios manages to ask.

“Whether you wanted to carry young or not.”

Wait…what?

Laios’s brain is spinning. He’s male, so he knows he can’t carry young. After all, he doesn’t have a womb, and his body would have no way to nourish a growing life. But she’s acting like it’s actually possible, like there’s a way to do it.

“H-how?” he stammers, confused and yet profoundly curious.

The kelpie’s smirk returns fivefold.

“We have two major things we can do with our magic,” she says, kicking her feet back and forth playfully. “One, change ourselves from horse to human. Two, change our sex organs.” Her smile widens, sharpening to something mischievous. “And if we really want to, we can push those changes onto someone else.”

Laios’s jaw drops open.

“Hypothetically, how would that work? I mean, would you add another hole, or just attach a womb to the one I have now? And would I have to give up my penis?” He’s in full flow now, unable to stop thinking about the mechanics of how that would work. “Would I grow breasts?”

“Wow.” The kelpie stares at him. “You’re kinky, you know that?”

Laios blushes.

“Oh, don’t get me wrong, it’s not a problem,” she says, getting to her feet. “Now, do you want me to show you? Properly?”

The pelt falls away—and Laios’s mouth falls slack.

“Well, that’s certainly a flattering response,” she murmurs, tugging him to his feet. “Though I can’t just call you ‘tall-man’ anymore.”

“It’s L-Laios,” he manages, struggling to decide where to look. She has breasts—round and full, one just slightly larger than the other—but he doesn’t dare look lower. The nipples are dark against her pale skin—pallor that would be unhealthy on a tall-man or an elf.

“Laios,” she says, rolling his name across her tongue like a piece of meat. “Armor off, please.”

His hands are moving before he knows it, shucking off the plate and chainmail as fast as possible. It crashes on the rocks at his feet.

“Oh, what a good boy,” she says, tongue flicking over her lips again. “So obedient.”

Laios feels his manhood stiffening upward immediately. He swallows heavily. His pants and underclothes are tight against the skin now.

“And eager,” she laughs, stepping closer. “Now, I want you to look me in the eye, and tell me exactly what you want, Laios.”

“I-I want you to give me a womb,” he whispers, shamelessly. “I want you to tell me what’s happening as you do it. I want you to fuck a baby in me.”

She pauses.

“Well, sadly I think you might have to wait a while for that,” she says, “since I’m not in rut, and your party’s probably worried about you.”

Laios’s face falls.

“Then again…” She steps forward, close enough that her breasts brush the fabric of his shirt, and leans in. Her nose and mouth brush the side of his neck. She sniffs, nuzzling into him—and lets out a groan. “You smell divine, and it wouldn’t be the first time a pretty boy managed to get me to rut a week early.”

Laios goes a little weak at the knees.

“Tell me about it,” he pleads. “How would it work?”

She sighs into his neck, taking in his scent.

“I would lean in, run my hands over you, get accustomed to the shape—and when you were ready, I’d add in a little magic, bit by bit. Tease you, tell you to watch the change, or you wouldn’t get to cum. And then, when you were all ready for me, I’d change myself too. And then I’d push inside, breach your new hole for the first time and watch you moan.”

Laios, without meaning to, lets out a soft whine. He’s leaking now, the front of his pants so wet he knows she’ll feel it soon—if she hasn’t already.

“And then I’d hold you down, and push your legs wide as they’d go, and fuck my eggs into your brand new hole,” she continues, one hand snaking inside his shirt to rub over his pecs—and suddenly, viciously, give his nipple a twist.

Laios keens, high and loud and absolutely desperate, as he crumples to his knees. She goes with him, tugging his shirt aside so her mouth can latch over his nipple and kiss and suck and bite. He gasps, a little sting of pain zinging through his chest—but his cock is straining as far as it can, confined in his underclothes, and Laios would be lying if he thought he didn’t want her to do it again. And again, and again, until his skin breaks and she can lap at his welling blood like a cat.

“You’re a smart boy, so I’d tell you all about my eggs as they go in,” she says, pushing Laios gently down onto his back. “How they’re like shark eggs, leathery and soft, and how they’ll push your new womb as full as it can go. How each one carries a little tiny kelpie inside, just a little pulse of life so small you’d barely see it at first. How they’d feed on everything you eat, and how they’ll thrive on every meal and swell inside you until you’re so swollen you can hardly move. How I’d make you a nest, as cozy and soft as I could, and tuck you in and curl around you till it’s time. How you’d bear down and lay them at last, and I’d hold you close and help you through it. How you’d hold them, watch the little heads poke through the egg casing, and how you’d fall in love with your babies right there.” She pauses, nips his throat, and adds, “You’d be such a good mother for them, wouldn’t you?”

Laios’s choked gasp turns into a cry, because his back’s arching, and he’s cumming into his underclothes, hard, harder than he’s ever cum before.

Panting, he flops back, euphoric. Through the daze, he realizes he’s thinking aloud.

“So kelpies have egg cases like sharks? And you don’t leave them, but have a mate carry them like a seahorse? That’s so clever! Wait, does that mean that any pair of kelpies can mate, if they change their genitalia? That’s brilliant, because you’re one of the rarest monsters in the whole dungeon! You’d have to be able to adapt whenever you saw another one of your kind, if you wanted to carry on the species!”

Fuzzily, as he comes back to himself, rambling excitedly all the time, Laios finds the kelpie staring at him.

“What?”

Shaking her head, she says, “You’re such a nerd.”

And then their eyes meet, and they’re laughing so hard they’re almost cackling. She flops onto the floor beside him, her teeth bared joyfully in a grin.

“Could you…actually do that with a tall-man,” Laios asks quietly, staring at the ceiling, “or were you just indulging me?”

She smiles, soft and mischievous.

“Come back and see me in a few weeks, Laios,” she says, “and I guess you’ll find out yourself.”
