You had at first been taken back by the fact the school had a Merfolk Club. After all while the mermaiding trend was growing it wasn’t what many would consider ‘School Club’ material yet there it had been on the list of clubs, its location being within this basement pool within the school.
Plus in fairness you were a mermaid lover yourself and it sounded great to meet and hang out with fellow mermaid lovers while swimming with them playing merfolk so... no harm, no foal in choosing to join this club you thought as you headed to the club’s meeting area.
As it turned out the main meeting area was divided from the hallway by two changing rooms split between genders and clearly you chose to use the girl’s one. For the most part it was as one would expect; slightly damp floors, no windows bar just above the doors, benches to be sat on if needed when getting change, tall lockers for storing clothes and possessions while using the pool.
But you quickly noticed you weren’t alone as just around the corner a bob-cut raven haired girl from the Junior grade division currently wearing a red bikini top and white Sarong was closing up her chosen locker just before noticing you “Oh... sorry. I’m running late” she apologized. “Just arrived about joining the club” You returned before introducing yourself “Ruby Alan. Freshman”. “Colette Thompson. Junior which would place me two grades above you” the girl returned.
“Oh right. As your joining us and I’m here I best help you go over how this club works” Colette then realized before escorting you to this steel cabinet just by the door to the pool and opened it to a collection of swimming tails clearly for club members to use. Oddly well crafted ones as their scale patterns seemed very realistic, coming in various colors with a good sized monofin of a lighter color of the scales with a matching series on the back. “These look like master crafts” You remarked. “Have to agree” Colette responded before getting to another point “Just in case what kind of swimsuit did you bring between a one or two piece?”. “...two” You admitted “I mean this school doesn’t have uniform swimsuits outside of competition”. “Then if desired you could like I am today go covered” Colette assured which confused you.
“Oh... sorry I jumped a bit” Colette apologized “mermaids here can go top-on or topless. Nothing forcing you”. “What does it matter if I brought a one or two piece though?” you asked. “These tails can’t be worn with anything in-between. You’ll see” Colette assured “Now all you need to do is pick your color”. “Alright then” you accepted before getting down a blue tail. “Odd I’d assume with your hair-” Colette started. “Blue’s my favorite color” You assured. “Fair enough. Now let’s get changed besides our tails and join the others” Colette accepted before returning to her locker and pulling out a deep red tail:
