Pairing: Merman x F!Reader Tags:  teratophilia, breeding, oviposition, age difference (reader is over 30 but merman is… pretty old according to human standards), size difference, reader is implied to be chubby, very soft with bits of condescension Word count: 1.5k Summary: You’re finally ready to start a family with him.

Note: Minors DNI! This is weirdly soft for this blog. Born from a very intense dream I had. Pwp with a lot of feelings… Very soft but ONLY smut. I’m working on some sketches with him, so keep your eyes peeled haha. (Due to work I won’t be able to show you these until next weekend-ish though!) Don’t think too hard about this - it really is just a smutty dream I had. Request are open!

He smells like sun and brine.

You're nestled into the great expanse of his body, clawed, blue-ish hands gripping the fat of your belly while he holds you up, your bare chest exposed to the morning sun. His grip is tight on your waist, the muscles of his arms working while he moves you up and down on his cock, his hips chasing after your cunt with every upward motion. The brisk temperature makes your skin prickle- his soft stomach is the only source of warmth against your back and his rough skin moves in waves against you. He’s slick with water and sweat as he slowly fucks up into you, labored breaths wet and hot against your ear. The feeling is unbearable. Your legs are spread wide, feet moving lifelessly against solid stone as they’re rattled around by his thrusts- although he’s gentle you feel like you’re going to lose your mind at this point. He’s simply too big not to completely wreck you, any preparation be damned. At almost twice your size, he could easily tear you apart. "I can't take it anymore-", you sob, speared on his tapered dick. You mean it.

He has the girth of your closed fist and the length to match. It’s all you can feel in this very moment, the sweet and prickly pain of being stretched to the limit is maddening. 

"You can and you will, little one", he says, his brogue so soft and caring, yet relentless.

He has been nothing but kind so far, stretching you on his fingers before slowly splitting you inch by inch, bit by bit- always a sweet word flowing from his sharp-toothed mouth into your ear, always pausing when you beg him to. But he never stops. Not that you want him to. It’s the sweetest kind of torture - so full of him until it hurts, so lost in the sensation that there is only him, him, him in this very moment. The world could end this exact second and you wouldn’t notice. How many times have you been in this position? Too many to count. It’s so familiar, yet different- now there's a rough determination in his thrusts, in his whole demeanor. He fucks you like a man starved and it makes your brain short-circuit.

"This will be one of my last seasons, sweet thing", he murmurs against the shell of your ear before gently biting down, sending a shiver through your whole body. It’s not like you don’t know that - you’re very much aware that this could be his last shot at having children with you - but the fervor of his words makes you cry out regardless, desperate to receive his eggs this time. He’s old by human standards- at least thrice your age. Physically, you’d say he looks like he's in his late 40s - and he hasn’t aged a day since you met him, roughly ten years ago. But even so, he ages like the rest of earth’s living, breathing creatures. Ever since you started your courtship, he has been nothing but patient. You not only needed time to adjust to your unusual relationship- but to enjoy your freedom. You wanted kids, yes, but not after a year of being together. It had been strange to him, his customs so different from human ones, but he had accepted your decision. Now that his window is closing, he has grown restless - luckily for him, you’re finally ready. “Please-”, you choke on your words when he strokes over your g-spot. “I want your eggs, so bad-” An approving rumble leaves him in response. “Keep talking like that and you’ll carry them in no time, little one.” A kiss is pressed behind your ear and he starts to fuck deeper into you, rattling you in the process. You whine and sob as the pressure builds, the familiar feeling of being so close that it almost feels like you have to pee is almost painful by now. You know he isn’t anywhere near reaching his peak, but having an orgasm is supposed to make this easier for you, according to him.

He's just so big. You feel dwarfed by him, especially when he coils his tail around you, 

shielding the two of you from prying eyes. His hand easily sprawls across your belly, his thick fingers long enough to reach deep into you when he splits you on them. He doesn’t, now - but he presses into the soft skin of your lower stomach, the pressure electrifying and just right and- You finally cum. It rolls over you in one large wave, makes your toes curl around nothing and your head bends into your neck until you can stare up at him. He gently fucks you through it, calloused hands gently massaging your tits as he hums into your hair. “There you go”, he mumbles tenderly. “There, there.” Finally, your full weight is settled into his lap. He’s no longer holding you by the waist, his hands have started to twirl around your shoulders in gentle touches instead. Your orgasm has made you so sensitive that the tip of his cock still sends fluttery sparks through you, even though he’s not moving anymore. It borders on uncomfortable but you’re too spent to complain. “Ready now?”, the fingers on your skin go from gently to heavy as they dig into your skin. You stare up at him for a moment, at his gentle eyes that study you from above. They swim with love and arousal for you, icy cyan pools you could get lost in for all of eternity. A nod is the only thing you can manage in response but it’s enough for him. “Alright”, he smiles before he paws at your waist again, fingers weaving themselves into your soft fat. You’re tipped over just so - body forward and ass pressed  into his lap and he starts to move again, slowly this time. It’s not for pleasure, it’s to stimulate something else entirely- You feel it before he can warn you. Something round and hard, as big as your curled thumb, slowly travels upward. It’s a strange feeling, especially through his skin. He grunts with exertion above you, hands turning into iron around your body, but not for long. It only takes a few more seconds until you can feel a distinctive snap within you, then something hot and wet - and Blue relaxes. A moment of peace, then he ruts upward and you gasp. The egg is nestled against your womb, its gooey shell hard and warm. It pummels its way through your cervix slowly and without mercy and it hurts. It’s encased by slime that sticks to your walls, almost gelatinous in nature, but it doesn’t help with the sheer force needed to pry open your deepest point. “Blue”, you press out through clenched teeth, scared and hurt. His fingers dig into you in response, a try at a reassuring gesture. “Shhh, I know, I know”, his voice is gentle and low as he strokes over your belly, soothing your tears. It does very little for you but you try to breathe through the pain anyway. The first egg takes minutes to finally slip into your womb and you sweat and cry your way through it. Blue shushes you through the process, peppering your slick skin with kisses and encouraging nips - it doesn’t really help, but still you lean into his touches. “No more, please, Blue”, you roll your hips away from him after the first one is inside, a fruitless attempt at getting away from him. His dick is sheathed too deep within you and his hands are like iron around your wrists. He tuts at you- a noise that distinctly reminds you of someone chastising their lap dog. “It’s okay, sweet”, he says, ignoring your squirming. “The second one will go in easier, just bear with me.” As if he’s trying to give his words more weight, he settles deeper into you, so close to your cervix that it sparks sharp pain that makes you clench involuntarily. “It’ll get better. Just wait a little. I promise.”
