After reuniting at a high-school reunion 20 years later, a porn director persuades his now 36-year-old married former classmate Saori to make her debut. The film follows their reunion, drinks and life updates, and the mildly erotic social-media photo that unexpectedly made her popular. During a test shoot, her mature F-cup body spills from a tiny swimsuit and her thick pubic hair leaves her squirming with embarrassment. Still conflicted about appearing in porn, the mother finally allows her first sex scene to be filmed at home and cums repeatedly.
