kokoro and her master (Pixiv Fanbox)

Maiko and GEISHA are not prostitutes. Their jobs are to entertain their guests with traditional classical singing, dancing and cultured conversation. However, Kokoro broke the rules of the GEISHA business and regularly had sexual relations with an old gentleman of power and wealth. This is because Kokoro has come to love sex with men of the father's age or older in order to fill the loneliness of having no memories of her father.
