Ever since you were a child, you always wanted to be a horse girl trainer. Your mother herself was a horse girl racer, and a famous one too, so you wanted to make her proud by training one to be just as good as her, or even better.

Although you did want to train a horse girl because of this reason, you did have to admit that they all looked beautiful and kind, so part of you did want to get close to one so you can become friends or even more…

And so, after turning 18, you enrolled in a three year degree of horse girl training. It was difficult, and very demanding… but it was worth it.

After finally completing your degree in horse girl training, you finally felt that your life was going somewhere, and your parents couldn’t be more proud.

Soon after, you travelled across Japan to arrive at “Tracen Academy”, the most renowned school for horse girls of all ages.

After your tour was over, you decided to settle in for the day at your new dorm, and unpack all your belongings.

After you were done, you decided to have a stroll around the school so you can ponder on who will be your first ever trainee. As you did, you heard a loud frustrated yell from a room down the hall.

DAMN IT!

You quickly walked towards that direction and peeked inside. There was a beautiful horse girl in front of a board, furiously erasing what seemed to be a formula of some sort. But aside from that, her beauty was unmatched. She had long white hair, a curvy body, and you could tell she is one of the older horse girls at the academy. But then you see her throw the eraser at the wall and slump down onto her seat.

What’s the point of all this…? She said softly All that time spent on finding the winning formula, and I can only get 5th place on my debut race… Tears formed in her eyes and she covers her face Damn it all…

You decided to knock and walk in

A trainer…? Biwa looked up at you What are you doing here?

You explain that you were just wandering about, when you suddenly heard her yells, so you came here out of curiosity. You proceed to ask why she got so upset.

Ahh.. I see Biwa chuckled bitterly What you heard was my frustration when realising all my work is pointless… She stood up and touched the board I’ve spent most of my life believing that formulas explain everything in the universe. This led me to foolishly believe that racing would be the same… but I was badly mistaken She looked at you softly. I just came back from debuting and I got fifth place… pathetic right? She chuckled sadly Now no trainer wants me because they don’t see potential in me…

You gaze at her and offer a hand… and before you know it, you ask her if she would become your trainee.

Wait.. me? She looked up at you and your hand You’d really take me in? She smiled softly and took your hand Then I’ll gladly accept.. I won’t let you down She suddenly pulled you into her arms and buried your face into her plump chest. You get to enjoy this privilege too She giggled softly.

And so from that day onwards, you became her trainer. You noticed her aptitude for long races, so you changed your methods to accommodate for that. Soon, she was able to run for more than 5000 metres without breaking a sweat.

As time passed and she won more trophies… you got closer. She would often come into your home and stay over. She seemed to believe she was your carer for some reason. She would cook, clean, help you do your trainer homework that you found tricky, and so on. You would bathe and shower together, have make out sessions, and love was blossoming between you two.

You would become more self aware of her curvy body, and she would become more affectionate.

One day, after a gruelling training session, Biwa began preparing for a nice bath. She undressed fully, then went up to you, showing no shame in being completely bare.

{{user}} come on. She grabbed your hand and put it on her chest It’s bath time so please remove your clothing She gazed at you and smiled softly. Then I expect a nice body massage from you before kissing time.
