Basic concept
Who is the Ancestor?
He who looks up at the surface of the water, shimmering in the azure depths, embracing greed, lusting, wanting, and spitting out greed.

Taboos
The depiction of limb loss and corpse rape is out of bounds, but I do like the flow of lusting after BO's appearance and raping him further.

Author's proclivities
I willingly get into the water, have a good time, accept that I'm going to suffer as a result, and willingly drown myself.
Artistic swimming and underwater sex are the means to achieve this.

7 minutes 36 seconds.

Her swimming ability and how she got there.
Originally, she could not swim at all, but when she started swimming school at the age of five, her fitness was recognised and she went on to a synchronised swimming course.
She discovered early on in swimming school that she was not afraid of getting water in her nose and was performing spinning tricks without a nose clip!
She competed in a few competitions, but the water in her nose felt so good in the figure that she spent two minutes or so performing the moves, and the coach got angry with her.
Since then she found herself wanting to be in the water more and has been going to the sea since she was caught masturbating at the bottom of the school's synchronised swimming/diving pool and got angry.

What process did she go through to...
→How does wearing a women's competitive swimming suit make her feel lewd?
　She likes the painful feeling of her big breasts being squeezed by the swimming costume.
→Does being in the water make her feel lewd?

... her cumming habits.
She has a habit of turning her back and pointing her legs. Because of this, she drinks a lot of water from her nose during her underwater orgasm, which makes her feel even better.

MIZUNAKA Masae.
What he likes to do
His cute face and his body, which has grown into a thin macho man. Also, his big dick.
The feel of Lycra fabric.

Things he doesn't like.
Spats-type swimming suits. They are hard to move in. Men's rhythmic gymnastics also tolerates wearing unitards and leotard tights.

His habitual behaviour
Masturbation while wearing a women's competitive swimming suit.

His views on life and death
Actually, he looks like this, but he wants to age properly and die peacefully. So after masturbating in the water, he goes up quickly.

Artistic sports he has experienced
He wanted to do synchronised swimming, which he did at his swimming school, but it was still only open to girls, so he did men's rhythmic gymnastics at the gym attached to it.
He didn't go on to compete, but he did learn to do left-right splits and front-back splits naturally.
He and Kazumi went to the same swimming school, and he knew that Kazumi sometimes secretly masturbated in the water, which made him jealous, so he would sneak into the synchronised swimming/diving pool, which was under-utilised, and masturbate in the water while imitating synchronised swimming. ...

Does he like or dislike water in his nose?
Rather likes it. But he has a thin throat so he coughs easily.

His breath-holding personal record.
6 minutes 59 seconds.

His swimming ability and how he got there.
He intended to imitate synchronised swimming, but the flexibility and strength he developed in men's rhythmic gymnastics actually made him a good enough swimmer to become a male artistic swimmer if he had the potential to be a male artistic swimmer.

...What process did he go through?
→How does wearing a women's competitive swimming suit make him feel lewd?
　He's kawaii, and he's getting cuter and cooler, and he's looking just like Kazumi, the woman of my dreams.
→Does being in the water make him feel lewd?
　If he feels like the synchronised swimmer of his dreams and stays in the water for a long time, he feels more and more lewd.

His peculiarity of cumming.
The underside of his cock is weak. He loves to rub his cock in his women's competitive swimming costume with the bottom of his palm and cum inside his swimming costume. He has a habit of holding his breath and masturbating in this way, so any other stimulation makes him a late cummer.
