Koimari Moeka

After graduating from university, she joined her current company.

Having spent her entire student life surrounded by women, she had no opportunity to interact with men and only talked to other women, so she ended up with a lot of information and knowledge.

She secretly read books and watched videos about sex and indulged in masturbation, but what excited her the most was the sound of other people having sex.

After being confessed to by Akizuki Yuuta, a senior colleague in the department where she was assigned, the two started dating and had sex for the first time, but she felt something was missing.

When she masturbated to a recording of their sex, she became so excited that she came in no time, but she didn't tell anyone about this sexual fetish because she was worried that it would turn him off.
