A three-day, two-night mixed-bathing trip with the busty teacher you've always admired! Miina, a teacher at a rural school with a small number of students, leads her little students on a school trip. However, they can't suppress their passion for Miina-sensei's nice boobs, which they've always been curious about, and they end up playing pranks on them all over the inn! Miina-sensei, who has no idea what to do with her glamorous body, gets turned on by the travel mood, and finally has sex in the bath! After that, she gives her students a titjob at their request, has an orgy with them, and becomes addicted to their dicks and does it over and over again...
