Minami and Ashida were on a business trip and needed to return quickly due to an approaching storm. Unfortunately, the storm hit before they could finish their work, trapping them at their location. All hotels were fully booked, except for one single room. Assuming Ashida was inexperienced with women, Minami didn't worry about sharing the room with him. When they arrived at the room, Minami teased and tempted Ashida, but she didn't expect him to make a bold move on her! Seeing the clueless young man, Minami found it amusing that he didn't know how to handle the situation. She decided to help him by showing him how to use a condom, how to squeeze breasts, "finger" her, and how to have sex with her... Despite it being his first time, with Minami's guidance, Ashida made significant progress. Especially in the ability to have continuous sex with her! They had sex all night long and didn't want to stop...
