Yui Shinjo is a sexy woman wearing a pure white knitted dress. She's on a long vacation and hasn't used her vagina. Having seen hundreds of penises in private, she prefers smaller "safety penises." Yui enjoys rough sex and has even filmed 7P scenes, so she came to film this to stimulate her long-unused vagina. Her fair vulva is wide open in an M-shape, as red as pink lipstick. Stimulated with a vibrator, it becomes even redder. A hard "safety penis" is inserted into her bare, wet vulva, and she is breathless from the long-awaited continuous pleasure. Finally, Yui is extremely satisfied with the semen that was ejaculated into her vagina for the first time in a long time.
