Rena Kawashima(19), a 175cm tall middle-distance runner who has competed in the national championships in the 800m, makes a flustered AV debut. She attended an all-girls school and has only had one experience with a man! She inappropriately puts a toy in her vagina and sprints down the track, and her long legs are used to capture her pistoning from an amazing crotch-to-crotch angle. She has her first double blowjob experience, and her first threesome leaves her weak at the knees.
