Marina Shiraishi enjoys a luxurious two-day, one-night hot spring trip filled with intense pleasure. After being forced to abstain from masturbation for a month, her desires run high—she's finally allowed to masturbate in the car, then pleasured with sex toys at the inn. In the outdoor bath, she gets fucked by an older man, followed by restrained oil play in the room for a sensual experience. In the banquet hall, she engages in a wild 4P with three men. The next morning, she's surprised with a wake-up fuck. Ultimately, she realizes, "I guess I really am a masochist after all..." and completes the trip with total satisfaction.
