## Description
A girl accepts and seeks out an unusual form of pleasure....

Mutsuki Academy――

Yayoi Unohana, a former student at the school, sees something she can't believe. She sees her classmate Yuki Samejima having intercourse with a large creature......

An unbelievably large creature――
Yuki was moaning with a face that she never usually shows.
Yayoi is engulfed by this unusual situation and watches. When Yuki's voice brings her to her senses, Yayoi flees from the scene.

She asks if she, like her, would like to be partnered with this "special pet"!

## Characters
### Unohana Yayoi (卯花 弥生)
A female student at Mutsuki Academy.
She is in the same class as Yuki Samejima and is the committee's chairwoman. She has a cheerful personality and treats everyone without distinction, but she is also easily swayed. She's the chairwoman not because she wants to be, but because she was forced to be.

She saw Yuki getting involved with a creature, and asked her if she could be a partner for the "special pet" as well.

### Samejima Yuuki (鮫島 悠姫)

Under the guise of assisting her father's research, she engages in daily interactions with various creatures.

She is sometimes so consumed by the pleasures of these creatures that she is unable to stop herself.
