High school girls who volunteer at a nursing home adhere to the teachings they learned when they were young, ``Be kind to the elderly,'' and don't refuse anything they ask. Erotic old men who take advantage of such kind hearts and sexually harass them. He pretends to be stupid and touches her butt, calls her to his room with his friends and locks her up, pretends to be angry over something trivial and demands a blowjob as an apology... He is a devilish man who takes advantage of the privilege of being an old man and plays with the body of a high school girl who can't resist and even cums inside him... It doesn't come true because of his age!
