"Teacher... I won't tell your wife." A teacher is forced to share a room with Mitsuki, who fell ill during a school trip, to take care of her. She teases the newly married teacher, asking him to wipe her sweaty body. She shows him her wet crotch, destroying the priest's reason. He is drawn to her young, smooth skin and embraces her madly, and before he knows it, he has ejaculated into her many times! The final day of the school trip, where he is seduced by a slutty gal, begins.
