A 4-hour video recording of a secret hot spring trip with a beautiful girl (IBW-982z)

Serving as teacher and student, and as part of a pair of loli twins, the teacher is sexually harassed, and the younger sister secretly engages in incestuous relations… Each of them harbors secrets that must never be discovered, yet they indulge in the pleasures of sex without any scruples in the secluded hot spring inn. Sex ensues immediately upon arrival at the room, and the entire night is filled with wanton debauchery, including sex in the Japanese-style room and the open-air bath. During the trip, the younger twins are developed and trained according to the author's preferences.
