A new part-time employee is taken on a one-night, two-day hot spring training trip, where she experiences mixed-gender bathing in erotic swimwear, intense piston-like sex, and verbal domination. The erotic encounters continue from morning onward, culminating in a scene where she spontaneously begs to be creampie-filled upon waking. This title highlights intimate, sensual contact in luxurious hot springs and the genuine, submissive reactions of an innocent amateur.
