Minami and Ashida were sent on a business trip when the storm hit, so they had to return immediately. But, unfortunately, a storm hit the mainland before the work was completed, so the two remained stuck in this place. Every hotel is full. There was only one room left, because she had always assumed that Ashida was a virgin and had never touched a woman, so Minami wasn't worried that he could accommodate her. When returning to the room, Minami deliberately teased and betrayed Ashida. But he didn't think he would attack her fiercely! Watching innocent young men who don't know how to smell girls or how to fuck makes Minami laugh. He immediately helped her, showing her how to put on a condom, how to squeeze her breasts, “crawling” and how to fuck her … Although this was the first time, thanks to Minami's guidance, Ashida gradually improved. Especially being able to fuck her endlessly! They both keep it up from dusk to dawn, but don't want to stop yet …
