Upwards.

She tried to not get too excited during her emerging, but it was hard as her energetic swimming movements made the dildo inside her swing wildly. The same water that felt cool on her skin was noticeably warmer by the moment it was reaching far enough into her vagina.

She grasped and leaned on the pool edge, breathing heavily. She saw the same wall opening she came from through the veil of her own wet black hair.

"Why am I... on the same side?"

"For a reason, silly! You're ready now!"

"Ready for what?"

Jen looked to the left and saw the mermaid suit still on display under the transparent cover.

"You got rid of everything that was in your way, now get your reward! I know you've been dreaming of this!"

"Dreaming of whaa?" — Jen was very far from ready to confront the voice. Her lower part was still in the water, experiencing the sensations, while her hands were trying to pull herself out of the water, but she felt as if she was doing it in slow motion.

"Remember your childhood dream? You were watching cartoons and then wanted to be a mermaid from the cartoon!"

The girl felt some memories going back to her, slipping through the closed door they were hid behind from her. These images were all she was seeing when her wet ass flopped onto the tiles.

"I asked my parents to get me a mermaid tail."

"They couldn't say 'no'."

"But it was such a disappointment. I asked them to buy a real one..."

"They said it wasn't a thing and there are no real mermaids out there."

"Even though Dad showed me that the entirety of young Internet had nothing better than I already had, I was furious."

"You have a chance now. It is right before you."

Jen focused on what was real and looked up. She already crawled half the distance from the mermaid suit on the display.

"You're a deceiver. It's a trap."

"Of course it's not! It's the ultimate gift. Fulfilling your dream is the least this place can do for you. It doesn't look like that 'swimsuit' or these 'cute white heels' at all, does it? Be the queen of the pool."

With her mind clouded by words she wanted to hear, the girl found herself standing near the glass container. There were two buttons on the panel now instead of one: one was 'HIDE', while the other was 'OPEN'. Jen pressed the second one, and the glass went away like the plastic lid did before, but downwards. She shivered from the colder atmosphere that was released from its boundaries.

"It must've been used for keeping it in perfect condition." — she said. Not that she remembered seeing any item in the mall in any other condition.

She approached the suit and inspected the tail that was hanging on the hangers. It was very heavy, with incredible amount of details both in the scaley outside and the fleshy inside with its peculiar texture and shape certainly designed to contain her legs.

The hangers were attached to the giant tube-like structure going high up and into the ceiling. They looked secure, and Jen decided that it would be much easier to get into the tail without putting it onto the floor.

"I'll just jump into it. Looks like the easiest way to do it."

She grabbed the hangers and soon witnessed her legs sinking into the tail. It indeed felt warm and fleshy but not wet or slimy, and that calmed her down. The tail's waist flopped against her own, and Jen gasped as the pressure her weight applied to its bottom caused the rest of the thing to encompass her legs and hips tightly and create a feeling of fusion. She gasped as her insides got pressed harder against the dildo she was still carrying in her vagina. Together with satisfaction from fulfilling her childhood dream, it formed an arousal of a highest kind.

But the dream was not yet complete, so the girl snatched the mask hanging above her and put it on quickly without paying any attention to the intricate mechanism it was lined with. The eye lenses were very blurry, and the mouthpiece that entered her mouth was quite large, and the girl started getting second thoughts.

The earpieces snapped onto Jen's ears, and the world around her went silent. Right after that, another revelation struck her: she could not inhale air through the mask!

The girl tried to take it off, but it already entered its closed state and would not open without a certain item, and Jen knew what that item was just as well as the fact she had seconds left to find a source of oxygen.

"This must be a water breather! I need to get to the pool!" — she thought lightning-quick, let herself fall from the hangers and started to roll towards her closest body of water.

*SPLASH*

Jen took a deep breath of water, and it remained in the apparatus in her mouth, while a stream of oxygen rushed to fill her needing lungs. She finally was able to look down to the new part of her body in its native habitat.

The dim light was falling down from the ceiling lights, refracting from contact with water and making the tail glisten in it. As Jen saw the bottom approaching much more clearly through the lenses, she tried swimming. A swing of her tail not only displayed its might, but also reminded her that the dildo was still inside, and there was no other course of action but accepting the constant horniness from the very process of swimming.

Jen's own legs were a thing of the past, she could not feel them as separate limbs anymore. The realization that she was now a real-life mermaid woke up everything she was feeling in the process of her transformation, leading her to the edge of climax. Another swing of the tail — and she would be there, but was it the right thing to have right now?
