Overview
Sawa joins her two nieces, Lala and Ran, on a hot spring trip in place of their mother. The girls, intrigued by Sawa's mature body, begin asking intimate questions and playfully touching her breasts, driven by growing sexual curiosity. At first, Sawa brushes it off, but their gestures gradually become more sensual, and she finds herself responding with pleasure. One night, while she sleeps, Lala and Ran surprise her and make her climax with their fingers. Overwhelmed by their innocent yet bold advances, Sawa is drawn into a world of lesbian submission.
