In the exciting school trip with the busty teacher series, up-and-coming busty actress Mei Hoshou appears! Mei-sensei is leading a group of little kids from the countryside on a school trip. The students, who are in the middle of their adolescence, go wild at the inn as if they had been waiting for this chance! They make a bold move on the teacher's big breasts, which they have been interested in for a long time, at the mixed-bathing hot spring! They gather around her and start groping her over her swimsuit, and finally have sex with her, as she doesn't seem to mind at all! It's a three-day, two-night lewd trip where you can cum inside grown women!
