At a hot spring inn in Gunma Prefecture, there's a stunningly busty female attendant, and the story follows a guest staying at the inn who sets out to seduce and fuck her! When dinner time arrives, he starts drinking and gradually seduces the attendant, leading to wild sex. Before heading to the bath, he calls her to his room, casually asking about the benefits of the hot spring while naturally convincing her to change into a yukata, letting his cock slip out. Her eyes lock onto his dick, and he gets excited by her reaction. For dinner, he enjoys fresh sashimi, tempura, hot pot—delicious dishes unique to traditional inns. As he pours drinks for the attendant and they both get pleasantly tipsy, he starts touching her big tits. Blushing, she whispers, "Let's go bathe together." The I-cup breasted attendant joins him in a cypress bath, where he enjoys her massive breasts and has the most incredible sex imaginable!
