Mermaid Trap (Mermaid Tf/Mc)

(Includes heavy Mindcontrol stuff.)

The water around you is clear and soothing, the sunlight filtering down in shimmering rays as you glide effortlessly through the deep blue expanse. The ocean has always felt like a sanctuary… peaceful, silent, and full of wonders. Fish dart in and out of the corals, the rhythmic sound of your breathing the only thing you can hear, and for a moment, it feels like time itself has slowed.

You’re enjoying the quietness, lost in the beauty of the underwater world, when a sound reaches your ears. A faint, desperate cry that cuts through the calm like a whisper in the wind. It’s strange to hear a voice here, underwater, and you pause, tensing instinctively. For a second, you think it’s just your imagination playing tricks, but then you hear it again, louder this time. It's unmistakable. Someone needs help.

Turning in the direction of the sound, you spot something in the distance, a figure emerging from the shadows of the coral. At first, you think it might be a trick of the light, but no, as you approach, it becomes clear. A mermaid.

She’s absolutely stunning, her long hair flows in waves like strands of silk, and her skin glows with an almost ethereal shimmer. Her tail, a mix of iridescent blues and greens, is tangled in chains that bind her to the rocks below. Her large eyes widen as she notices you, her expression a blend of panic and pleading.

"Please," she calls out again, her voice hauntingly melodic, "I need your help."

There’s something about the way she says it, the way her lips move, that makes your heart skip a beat. You can’t help but be drawn to her.

You swim closer, your curiosity piqued. The chains are wrapped tightly around her tail, making it impossible for her to break free on her own. It looks like she’s been stuck there for a while, her arms weakly pushing against the stone as she struggles.

“I… I can help you,” you say, voice muffled through the diving mask. You nod reassuringly, already beginning to inspect the chains, trying to figure out how to remove them. The urgency in her voice keeps you focused, but at the same time, there's something about her presence that fills the water with an odd warmth.

Her face softens, her eyes twinkling with gratitude, and she gives a small, relieved sigh. “Thank goodness… Okay, come a little closer. I’ll show you where to unlock them.”

You move in a little closer, your hand reaching out toward her, eager to help. But just as you do, her arms shoot up, fast as a flash, and before you can even react, her hands grip the sides of your face with surprising strength.

Your heart races for a moment in surprise, but it’s not fear. No, it’s something else. You blink, and before you know it, she’s pulled you closer. Her gaze locks with yours, and you’re caught.

Her eyes… those beautiful, glowing blue eyes… are all you can see. They are deep, captivating, like oceans in themselves. Everything around you seems to fade, the water, the chains, your thoughts... All that matters in this moment are those eyes.

Her hands are warm against your face, but it’s nothing compared to the heat that radiates from her eyes. Those eyes... they’re like nothing you’ve ever seen before. They pull at you, deeper and deeper, until the rest of the world begins to fade away, like distant echoes you can no longer hear.

You blink, trying to focus, but it’s impossible. Every time you try to think, her gaze grows stronger, pulling you further into a vortex of blue. The more you stare, the less you can see… Nothing exists but her eyes. Your thoughts feel like they’re floating away, slipping through your fingers like fine sand, and all you can do is follow the pull of her gaze. It's not just her eyes that captivate you. It's the way they command… no, demand your attention. You can feel the weight of them, like they’ve stolen your ability to think, to move, to breathe.

Her voice... it's there. You hear it, muffled and far off, like a voice echoing through a distant hallway. But it doesn’t matter. You can’t focus on it. You don’t have the strength to pay attention. The world is blurring around you, your surroundings a vague memory of what they once were. The water, the bubbles, the sensation of floating... all of it is melting away, pushed aside by her eyes, by the weight of her presence.

You try to move, to look away, but it’s like your mind refuses to obey. Her eyes are all you can see. All you can feel. You don’t even know how long you've been staring, but you don't care. It doesn’t matter. There’s nothing but her. Her beauty, her pull. You feel light, lightheaded, as though you're floating in her gaze, floating with nothing but her voice and her eyes.

Everything feels soft. Distant. Like the thoughts that once rushed through your head have been drowned in warm, thick honey, slow and sticky, making it hard to think, hard to remember. The only thing you know for certain is her eyes, pulling, pulling... deeper... deeper...

And then, just as quickly as it began, she releases you. Her hands slip away from your face, and her gaze moves from yours. It's like the floodgates open, and suddenly, you feel the weight of the world rushing back to you.

You instinctively try to follow her eyes, but something feels... off. Like molasses flowing between your thoughts. Each thought comes sluggish, slow, like wading through thick fog. You remember that you were underwater, that there was something important you were supposed to be doing, but... but what?

The pieces are there, but they don't quite fit together right.

The mermaid grabbed your face. Yes. And you... you were looking into her eyes.

What happened then?

You try to recall anything that happened during the time where she held you tight… but nothing. It just felt like a blissful hole of nothingness in your memory.

The next moment her hands slip away from your face and something feels... different. You try to steady yourself, to grasp at what’s happening, but your mind feels foggy, sluggish. You can’t quite focus, your thoughts moving too slowly. The water, the bubbles, the weight of the ocean, everything feels distant, like it’s out of reach. And then, the mermaid speaks again, her voice gentle and teasing, like she’s been waiting for you to catch up.

"Why are you wearing that silly thing?" she asks, her voice like the softest whisper against your skin. "You have gills. You can breathe underwater."

The words don’t make sense at first. Gills? You blink, trying to make sense of what she’s saying, but it feels like trying to grab a shadow. You tilt your head, feeling... silly.

Do you have gills?

You try to think, to remember, but... nothing. It’s like the more you try, the harder it becomes to hold onto. You look down at your neck, almost as if seeing it for the first time. There’s a strange sensation there, where her fingers had just touched you. A tickle, like a soft prickling under your skin. And then... you see it.

Gills.

You gasp softly, the realization sinking in as you feel the small, delicate slits beneath your fingertips. They weren't there before, were they? But no... they’ve always been there. You don’t know why you ever questioned it. Of course, you have gills. It makes perfect sense. Why would you ever need a mask? The idea seems... silly now, and you instinctively pull it off.

Breathing comes a little slower at first, a strange, new rhythm that feels alien, but... right. The mermaid smiles at you, and the softness of her touch on your neck makes the world feel warmer, softer.

"See?" she says with a smile, like she’s comforting you. "You’ve always had them." Her fingers trace along your neck, sending ripples of warmth through your skin. "You just needed to remember."

You feel a strange pressure in your chest, but the mermaid doesn’t give you time to process. She floats down, her hands trailing along your body, moving with an almost practiced ease. You don’t think to stop her. It feels right. In fact, it feels... wonderful.

"Look at you," she purrs, her hands skimming over your chest. Her eyes flicker to your breasts, lingering with an intensity that makes your heart skip. "You have such an amazing chest... So beautiful, so big."

It’s true, you realize, as she cups your chest in her hands, the sensation sending waves of warmth and pleasure through you. You had always known you had them, right? Of course you had. They had always been this full, always this round.

You blink, and it feels like something shifts within you, like something had happened in just that moment. But no... they’ve always been there, haven’t they?

You don’t know why, but you feel... silly for ever covering them up. She’s right. They’re perfect. Why wouldn’t you want to show them? Why ever hide them?

As her hands begin to gently open the zipper of your diving suit, you can’t stop the fluttering in your chest. Your breath catches, and it feels like something is... changing. No, not changing. Growing.

The mermaid massages your chest slowly, her fingers making tender circles, and you feel yourself expanding under her touch. It’s as if your breasts are swelling, filling with a warmth that spreads from the inside out. They grow bigger, fuller, until they’re undeniably massive, and with each tender stroke, the sensation intensifies.

Your thoughts scatter, and for a brief, blurry moment, you wonder why this feels so right. Why do you feel so... confident? Safe. So at ease in this moment. The sensations of your chest, of her hands on you, are overwhelming, and yet, you can’t focus on anything else.

The mermaid’s voice brings you back, though it sounds distant, like she’s speaking from far away, even though she’s right in front of you. "You’re thinking so hard," she teases, her tone sweet. "Something feels off, doesn’t it? It’s okay, sweetheart. Don’t think too hard about it. Just let go." Her hands continue to massage your swelling breasts, slow and deliberate. "I’ll keep growing them for you, until you’ve figured it out. You don’t need to worry. I’ll take good care of you."

Her words melt into your mind, and you can feel your body responding before your thoughts can catch up. You’re so distracted, so lost in the sensations. You don’t know what’s real and what’s not anymore, but the more she touches you, the less it matters. There’s a soothing comfort in her hands, a reassurance that you’ve always been this way.

Her fingers glide in circles over your skin, and with every pass, your body seems to shift a little more, your mind foggier, your thoughts slower. You can’t tell if your chest has always been this big or if it’s the way it’s growing now, but none of it feels wrong. It feels like it should be this way. You were always meant to be like this.

And as she continues to touch you, each motion so gentle, so careful, you feel a soft, steady warmth spreading through you. You don’t know why, but you feel more and more at peace. Your life is in the mermaid’s hands: your body, your thoughts… and you trust her completely.

You float in the water, your body heavy and light all at once, the world around you beginning to feel soft, like a dream you can’t wake up from. Every sensation is amplified, making it hard to focus, but the mermaid's touch is like an anchor, pulling you deeper into this strange, warm feeling. Her hands slide slowly down your sides, sending ripples of heat through your body.

"Im almost jealous," she whispers, her breath sending shivers across your skin. "You have such a lovely long fishtail and such a sexy, huge butt."

Her fingers brush along your back, gliding down to your hips. You can’t help but twitch, a shiver running through you at the sensation, but it feels so right. You feel her fingers press into your flesh, massaging the sides of your hips, your butt-… Wait... your butt?

Her hands continue their slow exploration, moving with ease, as if they’ve been here before. She’s so gentle, so confident. Her touch lands on your hips again, squeezing softly, and then your butt, her fingers curling in to press against the roundness of it.

"Huge butt," she murmurs with a soft laugh. Her voice is sweet, teasing, like she knows something you don’t.

You try to focus, try to remember what your body used to be like. But your thoughts are sluggish, like syrup thickening in your head. It feels hard to process anything, let alone your own body.

"Everyone wants to have that," the mermaid continues, her hands kneading your legs now, moving slowly from your hips down your thighs. "The size you sport." She emphasizes her words, making each touch feel deeper, more intense, as if her hands are molding you, shaping you, making you into something that fits her words.

Your thoughts get slower with each passing second, like your brain is wading through thick molasses, every sensation sticking to you and taking more time to process. She whispers more words of praise as her hands travel lower, and you feel your hips shift under her touch, like they’re molding, adjusting to her words.

"Long fishtail," she coos softly, fingers gliding down your legs to... your tail? Or your legs? You can’t tell anymore. There’s a strange feeling there, something new but familiar, and every time you try to focus, it’s like the ground shifts beneath you.

Your body doesn’t feel quite the same anymore. Your legs feel... different. Something’s wrong. Or is it? Is it wrong?

You try to focus on your legs, but they feel like they’re becoming part of the water, fluid and smooth. You can’t seem to make sense of it. But... but your tail? You feel it, or at least... you feel the space where it could be. It’s hard to tell anymore. There’s a heaviness, a weight... but it feels so natural now.

You turn your gaze down, trying to catch a glimpse of what’s changing, but the mermaid’s touch distracts you again, her hands now squeezing your hips, pressing into your butt with a possessive warmth. She sounds so sure, so confident in her words.

"Huge butt," she repeats, like it’s the simplest thing in the world. “You’ve always had this, haven’t you?”

And you blink. Had you?

You try to remember, to piece together the shape of your body before, but every time you think back, your memories feel blurry. Your eyes trace your curves, but your mind can’t keep up. What size was your butt before? And your tail... Was it always this long? Or is it... bigger now?

The mermaid’s words swirl in your mind like gentle currents, tugging at you, making it so easy to believe everything she says. Of course it has always been like this. Your body couldn’t have been any other way. She’s right. She’s always right.

Your tail, your hips, your butt—it all feels so natural, so right, as if it has always been this way. You can’t fight it. Your body follows her commands, her praise, her touch. The more she massages you, the more the line between what was and what is now blurs.

Every time you try to focus on the past, it slips further away, until all that remains is the present: her hands on your body - specifically, your hips, your butt, your tail.

You smile, feeling safe. Feeling confident. Because the mermaid wouldn’t lie to you. This is how you’ve always been. This is who you were meant to be.

The mermaid’s hands glide over your body again, tracing the shape of your long mermaid tail, moving over the plush curves of your massive buttocks, your waist, and stomach. Every touch is so soft, so gentle, like she knows exactly how to ease you into each moment. Her fingers brush against your breasts, squeezing them gently, as though they were simply an extension of your body, a natural part of who you are. It feels like she’s molding you, shaping you into something... more.

You barely register her movements, your body humming with warmth and pleasure, until she slides her hands up your neck, cupping your head in her delicate fingers once again. This time, it’s softer. More tender. You feel like you could melt right into her touch, but your mind... it still lingers. There’s something there. Something off.

Before you can try to focus, she pulls something from somewhere… Where did she get it from? It doesn’t matter. It’s a comb, and she starts gently combing through your hair, her fingers working with careful precision. The sensation is soothing, almost hypnotic, as she whispers softly to you.

“You seem to think a lot recently," she murmurs, the comb moving through your hair with rhythmic strokes. "It’s not your strong suit, but it seems to be really important to you. So okay, think about it. Really think hard about it. What is it that you have on your mind right now?”

You try to focus on her words, your mind sluggishly trying to catch up, but it’s so hard. Each pull through your hair feels like it’s soothing your thoughts, relaxing you. It’s as if the more she combs, the more the fog in your brain thickens. You try to push through, but you can’t quite hold onto the thought, the idea of what’s wrong.

Your fingers twitch, and you feel something that you didn’t notice before… A soft, heavy weight running down your back, brushing against the tail that wasn’t there before... or was it? You can’t remember. But your hair... it's growing longer.

It’s pink, just like it has always been. Hasn’t it? Of course it’s pink. It has always been pink. And it’s so long now, floating in the water like strands of silk, almost brushing against your colossal behind, just as the mermaid had said. The pink strands twist in the current, flowing down your back, soft and long, like they’ve always belonged to you.

"Don’t worry," the mermaid coos, her voice like a soft caress. "You think, and I’ll make sure your hair is nice, pink, and long. Like always."

The sensation of the comb moving through your scalp is hypnotic, repetitive, soothing. You can feel each strand of hair, each delicate pull, as it becomes even longer, until it sways just above the swell of your backside, and yet, the question remains. What’s on your mind? Why does this all feel so right, yet you can’t place why?

The mermaid swims around you, coming to the front now, her eyes never leaving you. Her hands gently cup your face again, her touch soft and deliberate, tracing the smoothness of your cheeks, pulling gently at the corners of your lips.

She smiles sweetly as her fingers trace over your lips, feeling them growing fuller, plumper, as if the very act of her touch is making them change. You can feel them becoming bouncier, more inviting, her touch so light, so tender.

The mermaid’s fingers pull the corners of your mouth upwards, as if to lock a permanent smile in place. You don’t know why, but something in you welcomes the change, welcomes her touch.

You can’t put your thoughts together. Your mind is moving too slowly, everything blending into this gentle wave of pleasure, warmth, and bliss. The feeling of her hands on you, shaping you, making you perfect, is overwhelming. Still, you can’t grasp the thought that lingers on the edge of your consciousness.

Then she looks into your eyes, really looks into them, and you feel it. She sees into you. She knows.

“I know what’s wrong,” the mermaid says, her voice more confident, more knowing. Her words are like a cool breeze, stirring something deep inside of you. For the first time in what feels like forever, your thoughts snap to attention. Your eyes widen, and you focus entirely on her. You want to know. You need to know. What is wrong?

She smiles, her gaze soft but commanding. “You are thinking. That, in itself, is the problem.” Her words wash over you like warm water, and you can’t resist the pull of them. “You should only obey. Not think. Obey me. Your mistress.”

Her finger taps your forehead, and in that instant, a wave of bliss crashes over you. Your thoughts melt, slow and sweet, dissolving into nothing but pure, pink, and blue pleasure. It’s as if your mind is being swept away by the ocean, and the only thing left is the calm, blissful emptiness of obedience.

You let go.

Your thoughts are nothing now. You have no thoughts. All that matters is her. All that matters is her touch, her words, her embrace. You can’t think, can’t focus on anything other than what she’s told you: To obey.

And it feels so... right. To obey… To obey.
