The depths claim more girls to become finned whores

Kim, Opal, and Gretchen had bonded with each other in high school thanks to their mutual bitchiness. They knew they were bitches, they liked it, they liked it about each other, and none of them saw any reason to change. Men fawned over them, in no small part thanks to how hot they were, and other women largely stayed away from them for fear of being put down by the cruel trio.

Furthermore, the girls loved nothing more than showing off, specifically their sculpted bodies and new vibrantly colored hair jobs. A trip to the beach would afford them the perfect chance to do that and maybe pick up some hot guys as well. The three, mid-twenties aged women were all lazily swimming while the virus spread through the water.

Gretchen felt it first, a creeping sensation that crawled over her legs and up her torso. It felt like a cramp, but more pleasurable. She wanted to cry out to her friends, but the feeling spreading across her body was too seductive, and she didn't make a peep, even when her green bikinied body froze up entirely and she slipped entirely underwater, her green and purple hair lingering a moment longer before it disappeared too.

For a moment though, Kim saw her friend's hair on the surface of the water, and she immediately dove towards her. "Gretchen!" she shouted, groping frantically in the water for some trace of her friend and coming up empty. "Opal, help me find Gretchen, she's drowning!" Kim yelled, pushing her wet orange hair out of her face. She dove underwater, but only looked around a little before she saw that Opal hadn't moved. "Opal, what the hell are you doing?!" she yelled as she resurfaced, eyes fixed on her blue-haired friend.

"My fucking tits are growing, you cunt. Ooohhhh, it feels so good. Mmph, they're bigger than yours, Kim. Fuck, they're bigger than my hands! More, so good, more, more, mo-ooohhh...." Kim watched as Opal's litany was cut off with a moan, which was cut off in turn as she slipped under the water as well. The redhead looked around in horror to where her friends had inexplicably disappeared. She couldn't understand what was going on, why her friends had disappeared, or why she was abruptly struck with the most intense orgasm of her life.

"OH FUCK!! What is-AAH~AHHH!" She threw her head back as she screamed, all control of her body stolen away. Her arms wrapped around her extremely thin waist, holding herself tight as the rest of her spasmed. She felt herself sinking, but couldn't bring herself to care. She felt that if she struggled, she'd never feel so good again. To her lust-fueled mind, drowning was a small price to pay for the best and longest orgasm of her life.

She sank deeper and deeper, her body still trapped in orgasm as she fell. She could finally see Opal and, further down, Gretchen. They both seemed to be twitching and spasming, though not with the panic of drowning. Kim could see their bodies changing, becoming slightly sexier, but she mainly watched as their legs fused together and colorful scales spread across them, blue on Opal and pink on Gretchen. Kim looked down at herself as her orgasm became a steady thrum in her core and watched as the same change overtook her. Yellow scales bloomed into existence, and she could feel her new tail acutely, the powerful muscle primed and ready to propel in through the water. The changes finished as she finally settled on the sandy bottom of the lake alongside her similarly transformed friends.

"Fuck, I'm so hot now. Opal, your tits are huge!" Gretchen said, running her hands through her two-tone hair.

"I know! Kim, come suck on them, they're so sensitive," Opal said, dragging herself towards her red-haired friend, boobs half floating in the water beneath her.

"Fine, but you have to finger my cunt, and then I'm finding some hot guy to fuck. Every man wants to fuck a mermaid."

"Oh shit, you're right. Opal, come eat me out and then let's go find some hunks to rut," Gretchen moaned, bucking her hips erotically

"You'll have to come over here, Kim's doing way too good a job for me to move," the blue-haired woman groaned, both of her tits trapped by Kim's mouth and hands. Gretchen obliged, and soon the three bitchy mermaids were knotted together in an erotic pile.

Mabeline couldn't believe what was happening to her. One minute she was diving down under the clear lake water to explore the beautiful depths, the next she realized she was unconsciously breathing underwater. She panicked for a moment, but nothing changed the fact that she could suddenly breathe underwater without issue. It seemed like a dream come true for the avid swimmer, who loved diving, snorkeling, wading, splashing, and exploring underwater more than anything else. She was in such a state of wonder that she nearly missed the growing pressure on her frilled, yellow bikini.

Almost.

Mabeline had always felt at home in the water, her thin swimmer's body lending itself perfectly to her chosen passion. Now, her body, one part in particular, changed, gaining size, weight, and heft. Her breasts swelled out, slowly undoing the knot that held her bikini in place until the complicated knot fell apart, her tits only barely hidden by the now loose fabric that clung to her hugely enhanced chest. She giggled, mind a blur, as her dull yellow hair burst with new color and length, pretty pink locks floating in the water around her. She settled on the lakebed, legs unconsciously pressed together as she checked over her new chest and hair, touching both to confirm they were real, though she spent quite a bit more time 'examining' the former.

If she hadn't been so absorbed with her new voluptuous breasts, she might have noticed the healthy flush of her legs darkening to match her hair. Her pelvis and thighs tingled, as if they had fallen asleep and were only just waking up. Finally, the feeling became too much to ignore, and Mabeline looked down just in time to see her calves fuse together and her toes to extend into a single pink fin.

She gasped and reflexively moved her tail, the strange limb not feeling abnormal in the slightest. It belonged to her, was a part of her, and she was having trouble imagining otherwise. In fact, she was having trouble remembering anything else at all. The knowledge of what it was like to have legs, what her job was, and who her family was all crumbled away like sand, until nothing remained but Mabeline the mermaid, who suddenly had a fiendish craving for cock, any cock, so long as it could satisfy her with a creamy reward. She smiled at the thought and immediately pushed off the lakebed to go find one.

Holly didn't like the beach much. It was hot, there wasn't much shade, there were always tons of people around, her pale skin burned easily, and the sand got everywhere. Still, her boyfriend insisted they go every once in a while, and she was always helpless to say no. He seemed to love everything about it that she didn't but she was willing to go with him if it made him happy. Her one solace was the water, glittering blue and wonderfully cool. She loved to lay where the water met the land and let the waves wash over her feet. It wasn't uncommon for her to nod off while she laid there, lulled into a warm nap by the sun and waves. This time, though, she was abruptly woken up by her boyfriend, Turner.

"H-Holly?! What happened to you, are you alright?!" she heard him yelling, dragging her out of her nap. She blinked blearily at him, slightly disoriented and confused.

"What do you mean, Turner? Why wouldn't I be...*yawn*...okay?" she said, stretching her arms out and trying to not slip back to sleep.

"Why wouldn't...you're...but your...Holly, look at your...well, legs?" he stammered. Not seeing what was so horribly wrong, Holly propped herself up on her arms and looked down to where she could feel the waves splashing against her.

It all looked normal until her eyes hit her waist, and instead of the cute bikini wrap she had put on earlier, found red scales joined with her just below her belly button and above her hips. A long tapered tail had completely replaced her legs, fusing them into one massive limb. Holly stared at it for a moment, before tentatively trying to move it. It responded easily, naturally, without any of the disconnect she had expected.

"This can't be real, can it? It has to be...be.....oh my....mmgh..." Holly's surprised denial faded as she felt a wave of feeling crawl up her belly from where the tail joined her. It felt like heat, electric tingles, head rush, and chills up her spine all at the same time. It didn't stop either, making its way up her body until it settled just below her collar bone.

It sat on her breasts, if they could be called that. Barely more than a slight rise in her anatomy marked with pale nipples, breasts had never been something she considered herself to have. But an involuntary arching of her back showed just how much that was changing. Two proud mounds were quickly rising from her formerly flat chest, wonderfully round and perky. Holly gasped again, her nipples pressed forcefully into her straining pink bikini top. She felt like she was stuck with her back arched as her new tits rose more and more, topping out at modest, delightful handfuls, before she finally collapsed back onto the sand.

"What was...how...the fuck is this?!" Turner yelled staring at his suddenly busty mermaid girlfriend, who was still breathing heavily on the sand at his feet. Holly couldn't respond though, as the bundle of sensation continued to climb up her body, trailing over her shoulders, zipping up her neck, before settling with finality in the middle of her mind. The feeling immediately faded away, only to be replaced by another that brought a bright flush to Holly's cheeks.

"Hah...mmhh.....ah, Turner...do you like it? Do you like me? Your mermaid girlfriend? These new big boobies? I know you always wanted to try a titfuck, do you think these are big enough now?" she asked, squeezing her breasts with her arms to create a undeniably sexy chasm of cleavage, the supple flesh practically begging for him to nestle his dick between them. Holly's excited flush and panting breaths betrayed how badly she wanted it, her eyes flicking between his own and the hidden pillar that fought against his shorts.

He couldn't deny that the Holly before him was a far cry from the cute girl he had come with, now transformed into a seductively adorable mermaid that was positively begging for his dick. He stared at her, every moment and pleading look sapping away his self control, until he finally said 'fuck it' and stepped with reach of Holly's hands.

"Yay! Be sure to give me a nice big load, okay? Every mermaid needs a pearl necklace."
