Spotting a sexy mermaid costume, Nikka pulled it from the shelf and handed it to Nina.
“How about this? Mermaids are sexy, right?” Nikka asked.
“A little sea slut? Oh fuck yeah. Max will be asking to fuck his little mermaid all the time. The tail has two holes, one for ass sex, and a front for tight pussy sex. I have a customer who only has sex with her husband if he fucks her as a mermaid.” Nina said as her nether lips flared to the thought of them fucking.
“I mean live out your fantasies, I guess. Ok, I’ll take it. Shells come with it?” Nina laughed.
“Oh yes, they’re the best part. They have stimulating nodes on them. They get your nipples stupid sensitive. Same lady says she climaxes more times from her husband sucking her tits than any other part.”
“Oh, ok then,” Nikka blushed at the thought of her own sex quivering in orgasm from Max sucking on her nipples.
After a short exchange, the two parted ways, Nikka heading home to try on the outfit, and Nina to the bathroom to pull out an ovipositor sex-toy egg that must have gone in too deep.
Opening her front door, Nikka was red in the face. She had never bought a sex-outfit before. Nor had she ever used a toy on herself. But as she opened her new mermaid costume, she had essentially done both. Peering at the inside of her new seashell sex-toy bra, she grew a little wet knowing soon they’d be massaging her breasts. Still needing to start dinner but feeling a little naughty, Nikka popped her blouse open and let it fall to the floor. Unhooking her bra, she stood there topless as she unwrapped her shells. Placing the shells to cup her breasts, she felt them hold to her like suction cups. Able to let go without them falling off now, she giggled as she saw herself in the mirror in her sexy new bra.
“I kinda like them. I could wear these as a normal bra. Hmmm wonder how they turn on though,” Nikka said reading the instructions. “Squeeze bra firmly to cause perpetual suction until removed.”
Giving them a firm squeeze, Nikka nearly jumped as the bra brussels around her nipples began sucking and squeezing her nipples.
“Hh---huuuu!” Nikka moaned as her knees buckled, a moistness in her pussy growing deep within. “H…. holy shit. It… oh my…. Fuuuuck…. It really… works. Mmm oh oh ooooh!” Nikka moaned as the suction pleasured her now hard nipples. By now her pussy was turning redder and slick; the crotch of her pants starting to spot with her juices.
“Ohh… mmm… I need to make dinner.” Nikka said making her way around the counter as the relentless sexual assault on her nipples continued.
Chopping a salad, Nikka groaned and moaned trying to be both productive and exploring the intense pleasure. after nearly 5 minutes, she couldn’t help but grind her crotch against the counter; using its rounded edge to play hands free with her button. It was through this that she realized the entire front of her pants were soaked. It looked like she pissed herself from all the pleasure; maybe she did a little. Clouded in her horniness, Nikka dropped her bottoms and panties, leaving her naked besides her new shells. Kicking them aside, Nikka grabbed hold of the counter and closed her eyes.
“Mmm. Max, I love the way you’re sucking my nips,” Nikka moaned, fantasizing them tonight. “Yes! Yes! Touch me! All of me! Take me!” Nikka moaned as she grinds her clit against the counter edge; leaving behind her juices. “Max! Max! I’m! I’m! Ooooooh!” Nikka screamed as a wet squirting orgasm hit her; splashing the counter and floor beneath her with her fem-cum.
“Ohh… oh that was great! No wonder Nina’s a nympho.” Nikka moaned bent over the counter.
Too horny and caught up in the continuous pleasure, Nikka left the soiled counter and grabbed the rest of her outfit; her sex making a wet noise as she walked into her bedroom. Slipping one leg followed by another into the mermaid tail, Nikka pulled it to her waist and then marveled at herself.
Peering at herself laying on her bed through the mirror on her wall, Nikka struck a sexy mermaid pose. She made a very sexy mermaid. She felt extra sexy like this. Someone could easily take a picture of her and she’d look beautiful. But at the same time, next picture and she could be a mermaid sex symbol.
“No wonder that lady wants her hubby to fuck her like this. Maybe Max will be ok fucking Mermaid Nikka whenever we have sex… at least for a week or two.” Cupping a breast, Nikka realized life was about to change forever for her. She had managed without sex all her life. But if this was how it felt now, she didn’t see herself going more than a day or two without sex now. Pandora’s box was opened, and just like her legs, it was gonna be difficult to keep them shut; that is unless she had her tail holding them together.
“Mmm…. S-s-so horny. I hope Max won’t mind if I start without him,” Nikka said reaching down and petting her clit through the front opening. “I wonder how many orgasms I can have before Max gets home,” she wondered aloud as her sex gushed and squeaked from her overly aroused juices.
“Oh! Oh! That’s it! Yes! Yes! Yeees!” Nikka’s toes curled in her tail as another orgasm splattered from her opening; covering her sex, the costume, and bed sheets in fem-cum. “O…o…one!” she said rubbing her clit intensely, not at all aware of her ears turning pointier.
But it wasn’t only her ears changing. Beneath her costume tail, she was bloating in size, her toes growing longer, a webbing growing between her toes and fingers. As she masturbated from one orgasm to another, the changes kept spreading. Soon, green fish scales started growing in under her boobs and on her lower body. And soon, there was nothing but scales from the waist down. With her sex-crazed trancing fingering her humanity away, Nikka didn’t even feel her legs fusing together. Or her ears fanning out into fins. Or her breasts swelling larger into GG cups.
It was only when Nikka’s now pulsing cummy pussy changed that Nikka was broken from her trance.
“What the… my pussy feels so swollen. And the lips are so,,, rough. Did I masturbate too much? What is going on down—AAAH!!! Oh nononono! What the hell is going on?” Nikka screamed as she saw what had become of her. Peering into the mirror, she saw herself, but it wasn’t her. Her massive tits! Her fish fin ears. Her wet glossy skin, and her scaly mermaid tail ripping her costume at the seams.
“No! I can’t! This can’t be. I’m not an actual mermaid. I’m… oh… oh no. please don’t rip. Stay on. No! no no!”
A loud long ripping noise echoed in her ears as her larger mermaid lower mass tore its way out; the fake mermaid costume now a tattered pile of cloths around her. On its own, Nikka’s large fish fin flopped out and fanned into its full range. With the exception of her still sucking shell bra, Nikka was a big sexy naked mermaid now; her large hybrid human-pussy and fish-slit, flaring with need.
“Ohhh… oooh… what is happening to me? Why is this turning me on? I’m…” a shiver rolled up her spine as a full body orgasm took her. Starting in her fishy fins, up her thick mermaid thigh area, over her quivering sex, across her tight sexy belly, forcing her to arc her breasts into the air, and creating a warm fuzzy feeling all over her face and head. More and more. Better and better. Until the warm tingling fuzzy feeling turned her disgusted shocked expression into a cheerful, sexy, gleeful one. With one hand groping a breast and the other playing with her monster sex, the feeling didn’t leave her until 2 hours later when Max opened the front door. For 2 hours, Nikka was at the mercy of her changes.
“Nikka, you home?” Max called out.
Nikka opened her eyes, once brown and beautiful, they were a sexy misty blue. A mischievous grin grew on her face. Positioning herself for Max to walk in on her, Nikka shook her tits to make sure all of her, from tail to tit, from pussy to face, all of her screamed of sex. Max would enjoy fucking his mermaid. He didn’t have a choice. She would be too much for him to resist. And while normal Nikka would relent, she was no longer home, Mermaid Nikka was here to stay, and Max was hers now.
