[Kaho Imai's lesbian debut!] Tired from her daily work, Kaho takes a day off and goes on a trip to a hot spring by herself. While relaxing in the women's bath, she is suddenly approached by a pair of beautiful women... Kaho is spotted by a lesbian couple looking for "tonight's fun" on their trip, and they get her drunk and make her cum with their melting lesbian torture for a two-day, one-night lesbian immersion! The bonus footage also includes an off-camera threesome after the shoot.
