Open sex in the mountains feels so much better than usual! The grandeur of nature makes Airi, a novice mountain girl, loosen up between her legs! An experienced and erotic mountain climber takes advantage of this and teaches her the wrong manners! "When Airi pass someone on the mountain trail, put your mouth on it before saying hello," "When having sex on the mountaintop, be louder than anyone else," "The mountain trail is the best place for sex," "Peeing on the mountain leads to sex"! An excellent work that focuses only on mountains and sex! Being surrounded by nature will make your mood and your ass loosen up!
