Reika, a recruited model who came for an interview, is invited on a trip to a hot spring, and then the photoshoot trip begins. This slutty woman with 96cm I-cup breasts is usually sexually frustrated and immediately gets into erotic mode. They go to an inn and have sex in a private open-air bath, and her huge breasts shake wildly in a cowgirl position. Reika writhes in agony as her beautifully contoured breasts are massaged. Then they return to the room and have sex to enjoy her plump body.
