## Description
I, Segawa Akira, am a normal boy who attends a normal school.
Besides my mother, I have two older women I've known for a long time, or rather, who I know well.
One of them is Hinomiya Yuu. I call her Yu-nee.
She's a teacher, but she's always kind and supportive, like a big sister to me.
The other is Takamori Sana. She's a childhood friend, a year older than me, and I used to play with her a lot when I was a kid.
I lost my father before I could even remember and don't have any siblings, but thanks to Yu-nee, who looked after me like a younger brother, and Sana, who was my playmate, I never felt lonely, even though I was young.
However, perhaps because I was always surrounded by them, I didn't have much contact with other boys.
Perhaps because of this environment, it took me a while to realize that my body was different from the other boys.
A physical examination at school revealed something strange about my body. Eh... Does a penis grow hair...?
Could it be... that I, uh, masturbate? Because I've never masturbated!? (No.)
After consulting with my older sister Yu, I was taken to a hospital where a beautiful and seductive female doctor works.
The doctor, who introduced herself as Tachibana Kimika, gave me some shocking results.
What?! If this continues, I might lose my manhood (penis)!?
That shocking revelation already broke my heart, but the treatment plan was even more unprecedented.
To keep having sex with women!?
And when my mother heard that, she said something completely off the mark: "You have to use proper birth control!"
No, no, no, I don't think that's the problem...
And so, a completely different, extremely exciting life began, completely transforming my mundane days...

### Hinomiya Yuu (陽之宮 優)
She’s an older woman who lives next door to the protagonist and also works as a teacher at his school. With her gentle, laid-back demeanor, she’s very popular with the students.

She’s a master of all household chores and boasts a body worthy of a gravure idol, truly the “ideal older sister” everyone dreams of at least once.

Having looked after the protagonist since he was a child and doting on him like a real younger brother, she’s, of course, more than happy to take care of his needs below the waist as well.

She absolutely adores the protagonist’s penis. With her voluptuous, motherly body, she’ll gently, and at times boldly envelop you.

### Tachibana Kimika (橘 貴美香)
The female doctor who becomes the protagonist’s attending physician. At the hospital where she works, she’s highly regarded as an outstanding physician.

She has an open and cheerful personality, but… deep down, she’s incredibly sexy and sexually liberated.

She takes a liking to the protagonist and, under the guise of treatment, tries all sorts of sexy things with him. Is her goal really just sex, or is there more to it...?

Her passionate and sensual lovemaking will overwhelm you, just as the phrase “being milked dry” suggests.

### Takamori Sana (鷹森 紗那)
A childhood friend who is one year older than the protagonist. No matter what, she’s always nagging the protagonist about this and that, but deep down, she can’t stop thinking about him, yet she just can’t bring herself to tell him how she feels.

Her slender figure is certainly nothing to be self-conscious about compared to other women her age, but she seems to be bothered by the presence of Yuu and Kimika.

Since she’s inexperienced, she’s a bit clumsy at first during sex, but her inability to be open and honest leads her to say harsh things without meaning to.

However, she cares about the protagonist more than anyone else. Driven solely by the desire to make him feel good, she always gives it her all.
