#ceto x reader

we should give the mermaid some lore :>

Here’s a funny thought: Ceto does not understand the concept of shaving down there (or shaving in general). So when you shave your pussy for the first time before Ceto goes down on you, she pulls down your underwear and gets whiplash when she sees your bare pussy for the first time. She is genuinely and utterly confused. Last time you guys fucked, there was hair down there. What happened?

“…Where is the hair?”

“I shaved it.”

“You shav— Why?”

She looks baffled, looking up at you and then looking back down at your naked pussy. She blinks, as if this is some kind of illusion that’ll break at any moment.

“I just wanted it to look nice for you so you could eat me out.”

“…But it already looked nice?”

the first night, you hear her panting and snarling through the cell wall. it doesn’t even sound remotely pleasurable, moreso akin to painful. her scent—saltwater and steel—is suffocatingly thick, and you feel it line the inside of your throat with each breath despite the shuttered doors and windows into her cell. something curls hot in your gut.

it’s impossible to sleep.

so the next morning, you offer to help.

ceto is barely lucid as you talk to her through a crack in the door. it’d be nothing more than— than an act of neighbourly kindness. she’s an alpha, and you’re an omega; the solution writes itself. ceto is hesitant, but the wildflower and petrichor scent of you is already starting to soothe the baying creature in her veins. so she lets you in, and shuts the door behind her with a click.

you find that she’s inexperienced; deeply so. it makes her unique among the alphas you’ve had in your lifetime. something about the way she quivers under you, thighs tense and teeth grinding so hard you can almost hear her jaw creak as she holds back from doing as she pleases… it makes the omega in you preen.

an obedient alpha—what a catch. the thought of sinking your teeth into that pale neck flashes through your mind unbidden, though it’s far too early for that. you settle instead for sinking down onto her knot, revelling in the way she shudders and snarls and cries at the rush of heat in her veins, crashing down like ocean spray against the shore. and she allows you to guide her through her next climax, and the next, and the one after, until her rut finally settles— for now.

vs after getting to know her

Ceto reminds me so much of an angry hedgehog. She’s so spiky looking and defensive all the time, but when you begin to stroke her hair she just flattens and calms down 🥺

Ceto: >:(

Reader: *pets her*

Ceto: :I

You truly do fix her LMAO. Or, more so tame her. I don’t blame her for being so easy to provoke all the time, but being in your prescience has truly helped the Lightkeeper calm down. You’re almost like her therapy dog in a way, except it’s more of a therapy girlfriend? Whenever you see Ceto’s anger flaring up, spiky strands of hair starting to puff, you instantly reach out to stroke her face.

“Ouhhhhh it’s okay baby. It’s okay calm down.”

“Hn?”

And sometimes those places are deep enough to where no one would look right, what I'm saying reader and ceto def fucked in those said places before

CW: Fucking in a forest, semi-public sex, penetrative sex, clothed sex, protected sex

So you’re saying that Ceto and Reader have fucked in the woods before? Well you’re RIGHT. They HAVE. Sometimes Reader tags along on Ceto’s little excursions because she thinks Ceto gets lonely out there by herself. Ceto doesn’t, she likes the peace and solitude, but she doesn’t mind you being there with her. You’ll sit next to her while she does whatever nature-y things her field requires her to do; collecting samples or writing reports on the wildlife. Eventually though, you and Ceto will take a quick break, and by break I mean a quickie because Ceto will take you right there on the tarp in the middle of the forest floor.

Your clothes are only half off as you shimmy out of your pants, with Ceto’s bunched up over her knees. The sounds of nature are an innocent noise to the lewd slapping of her hips against yours, pounding away under the forest canopy where no one else could find you. You and Ceto are quite far off the trail of a forest reserve, so luckily no hikers or tourists would find Ceto absolutely clapping you.

Also, considering that Ceto is always well prepared when heading outside, she definitely packed protection and lube in her backpack just in case. When she heard you would be tagging along, I could totally see her hesitating before stuffing the raunchy items in her bag.

CW: ur naked, exhibitionism (?)

Ceto is so attention starved despite not wanting to admit it. All you have to do to get her turned on, is to stare at her crotch long enough and the extra attention will get her dingaling shooting straight up. In just a few seconds, there is an embarrassing little tent in her pants and she’s quick to cover it up with a pillow.
