The purpose of a fun school trip isn't just sightseeing! Sneaking into the girls' dorm at night and hiding under the futon, your crush greets you in a more alluring yukata than usual! Both of us are excited! With reason lost, we start having SEX right away! Even though we're hidden under the futon, the suspicious movements definitely stimulate the other students, and before you know it, it turns into an orgy, developing into a miraculous night!
