Himawari Natsuno

In order to win a sumo tournament held in a nearby village, the girls participate in a three-night, four-day training camp with the village youth group. The young men assigned to record the events leading up to the tournament become aroused by the girls' innocent and voluptuous bodies, secretly filming and recording obscene pranks on camera. They then take the girls to a hidden spot and repeatedly force them to have sex with them.
