IBW-976 A bitch who invites a masochistic teacher on a social trip: Haru Kikuchi and Misakine

A teacher and two students are on a club trip to a hot spring. The students find the trip too rural and boring, so they seduce the teacher, play pranks on him, and set up all sorts of naughty traps! Things gradually escalate, and the two students, who have become like little brats, drag the masochistic teacher into a loli-erotic swamp that he can’t escape from!
