Tighten your vagina and fight for victory! Vaginal tug-of-war. (Umino Nana 10musume_081825_01)

Nana Umino is a girl with a rather glamorous, gyaru (gal) vibe. Her breasts are full, and her vulva is already soaked, even staining her panties. Nana is very confident in her vulva, so she uses a rope tied to the head of an erect penis for a fight! Frustrated after losing the match, Nana keeps demanding revenge. She accepts a punishment game and tries again! So, who will win?
