A nurse with I-cup breasts has been passionate about caregiving since school and works at a care facility. She fell in love with the facility's care manager, becoming deeply addicted to his sadistic, training-style sex. Realizing she is a masochist, she was drawn further into him. However, after a certain incident, they broke up, and since then she has spent her days masturbating while reminiscing about those memories. Meanwhile, a kindergarten teacher with G-cup breasts loved children since her school days, graduated from ● School, and became a nursery teacher. She caught the eye of the perverted kindergarten director, who subjected her to daily training sex, awakening her inner submissive. But due to his age and declining stamina, their affair didn't last long. Still, she can't forget those days and continues to enjoy masturbating. Both women, drawn by watching masochistic amateur AVs and intrigued by the idea of hiding their faces with masks, decided to participate.
