Calypso, the mermaid

Swimming was always a favorite pastime of yours. Whether it was for exercise or recreation, something about being in the water feels so natural and fun. You can see why Denise is part of both the basketball team and the swim team. You've made it a habit to try to swim as much as you can in the school pool. Sometimes you're accompanied by Denise or another friend, while sometimes you're alone.

One day, you found yourself passing by the school and notice the lights in the pool area on. You decide to take advantage of the opportunity and go for a late night swim. As you approach the unlocked natatorium, you see a girl floating in the middle of the pool. Her wet blonde hair cascades down her back while she faces away from you. You're eager to be able to swim with someone new.

"Hey!" You call out. "Are you from the night school?"

The girl whips around in shock. You can tell from her bare shoulders and the top of her breast curve that she's not wearing a swimsuit. She lets out a startled cry, throws her arms around her breasts, and dives down into the water, flashing you her ass as well.

As her bare butt sinks, you swear you can see something attached to her legs. Actually, she doesn't seem to have legs at all. A giant fish fin briefly rises out of the water before the girls dives underwater. Stunned by the event, you turn around and try to think about whether or not what you saw was real. On your way out of the natatorium, you notice a pile of clothes, including a pink seashell bra and bikini bottoms, strewn on top of a wheelchair. On top of the clothes is a student ID badge that read, "Calypso."
