Retired from work, divorced, and living apart from their families, these lonely old men spend their days in quiet despair. Their only salvation is 'Mirai,' the beautiful instructor at their cooking class. To encourage and comfort these men, Mirai goes above and beyond, gradually revealing her own lustful, seductive side. During after-hours lessons, she mashes yam into a gooey paste and sensually licks the old men's cocks. Her tight skirt reveals shapely legs and an erotic hip line, stirring even these aging men to full, throbbing erections. She boosts their confidence with creampie sex. In special sessions, she gathers the retired men for vegetable masturbation shows, lingering in the afterglow of their intimate lessons.
