NITR-448 Volunteer female college student and elderly person's intense kissing sex

A young girl and an old man, through caregiving, become aware of each other as men and women and develop a physical relationship. A female college student volunteering for future job prospects or social service is assigned to care for an elderly man who has lost his wife and lives alone with frequent illnesses. The old man thinks of the selfless and kind girl like a granddaughter, but the vigorous old man can't control his lust for the girl's ample cleavage, pulling out his penis from his diaper and masturbating with her apron. However, the girl who catches him in the act is flustered by the old man's erection. Thinking that attending to his lower body is part of caregiving, she serves him. After that, the two cross the line like kites cut loose from their strings.
