【Bust Development】
She was already a C-cup in fourth grade and grew to a D-cup by sixth grade, making her dread swimming classes because her bust would spill out of her school swimsuit.
By her first year of junior high, she reached an E-cup, and by her third year, a G-cup.
In high school, she grew to an H-cup.
At her AV debut, she was an M-cup, but later announced on her YouTube channel that she had grown to an O-cup.
【Personality & Background】
She discovered masturbation in elementary school, developing masochistic tendencies by choking herself or holding her breath while pleasuring herself.
In junior high, she began fantasizing about being watched.
She lost her virginity at 19 while attending a prep school for civil service exams.
Although she became a civil servant, the heavy workload and sexual harassment at her workplace caused her to suffer mentally, leading to her resignation.
She loves idols, Sailor Moon, Kamen Rider, and Pokémon, and often posts about her favorite fandoms on Instagram.
【Dark Past & Emotional Struggles】
She grew up in an environment where her mother's shouting echoed all day long.
Though she dreamed of becoming a singer, voice actress, or working in fashion during her school years, her parents forced her into a civil service career.
Even after deciding to quit due to the stress from workplace harassment, her mother fiercely opposed it.
When she struggled mentally after quitting, her mother blamed her, saying, "It's your fault for quitting."
During her civil servant days, she was diagnosed with schizophrenia, and self-harm scars remain on her arms.
【AV Debut】
After resigning as a civil servant, she applied through an AV actress recruitment page online.
She did some gravure work first, then made her AV debut in April 2022.
Once the shooting dates were set, she couldn't wait with excitement.
【Sexual Preferences】
She openly declares herself as a true masochist.
She enjoys being watched and ignored, and sometimes orgasms from the attention even before the camera starts rolling.
She dreams of being walked around with a collar and leash.
When the mood strikes, she masturbates by inserting a vibrator and using a wand massager on her clitoris, which is her favorite method.
【JAVJAV Commentary】
Appearance
She has an adorable, idol-like face paired with large, soft-looking breasts.
Her skin is pure white and supple, and her areolas are pale and beautiful.
Background
It might sound strange, but her story feels almost like something out of an erotic manga.
Her harsh upbringing might have been what awakened Momona Koibuchi’s masochistic nature.
The idea of a cute, busty girl growing up in a toxic household and blossoming into her masochism feels almost artistic.
(Just to be clear, this is not an endorsement of toxic parenting.)
Knowing her background stirs feelings of wanting to protect and love her.
We can only offer the highest respect to someone who overcame such trauma and chose to become an AV actress, and we look forward to continuing to support her.
【Trivia】
There’s an amateur sex video featuring someone who looks very much like Momona Koibuchi.
Personally, I think it might be her, although no one else seems to have made the same connection, so it could just be my imagination.
