Carnivorous lesbian Akari and slender, beautiful-breasted Miho are coworkers who secretly maintain a lesbian relationship. Taking advantage of summer vacation, they head to a secluded hot spring inn to deepen their time together. They steal secret kisses outdoors, then immediately start caressing each other in the room without unpacking. In the outdoor bath, they quietly cling together, licking each other's bodies and indulging in deep tongue penetration and cunnilingus. At night, they relax in yukatas under the glow of fireworks, sharing gentle kisses. Finally, they etch unforgettable summer memories through intense, passionate sex. Their love story unfolds here.
