[IBW-982] A collection of footage of a secret hot spring trip with a beautiful girl, 4 hours (Censored)

A teacher and his student, a pair of loli bitches who reverse slut-seduce their teacher, and a secret incestuous relationship with a sister without their parents knowing... Each of them has a secret that must never be revealed to anyone, but at a secluded hot spring resort, they indulge in the pleasure of sex without worrying about being seen by others. They have sex as soon as they get to the room, indulge in obscenity everywhere all night, have sex in a Japanese-style room, have sex in an open-air bath, and develop and train a loli girl to their liking while on a trip.
