A young girl and an old man become aware of each other as men and women through nursing care, and develop into a physical relationship. A female college student who is volunteering as a caregiver for her future work and social service is in charge of an elderly man who is prone to illness and lives alone after her wife passed away. She thought of her devoted and kind daughter as her grandson, but the energetic old man in her lower body couldn't control her libido in the plump cleavage that grew on her daughter's Tawawa, and she out of her diaper and masturbate in her daughter's apron. However, her daughter, who has seen her act, is nervous about the erection of an old man. Taking care of her simo is part of her nursing care, so she serves. After that, the two cross the line like a kite with a broken string.
