Yarimoku Beach ni Shuugakuryokou de!!

Excitement unfolds as we follow a group of students and their teacher on a field trip,they go to a swinger's club beach and they meet another group of students with whom their mutual desire overflows. First they must go to the part of the nudist beach to hang out then they can bring on their partner to the site of swinger's club to have fun and fuck all you can. It's a special education field trip for interested in sexual intercourse.
