Yuka, a married woman whose life with her husband has become monotonous, has a secret she can't tell anyone. Today, she's at a secluded hot spring inn with her lover. The man kneads Yuka's perfect figure and large breasts, and the two gradually drown in pleasure. In the car, in the open-air bath, they forget all about their family life and indulge in their affair. Her moaning form, shaking her chest, is a must-see.
