Despite her small and slender frame, Riri commands and manages the construction site, leading a crew of tough men. As a highly capable site supervisor in the demolition industry, she has earned the respect of all the workers. Takuto joins her company as a part-time employee. While returning from a site inspection, Riri and Takuto are caught in a sudden torrential downpour, and their car breaks down, leaving them stranded. With no other choice, they take shelter in the mountain hut they had just inspected to wait for rescue. In the cold of the night, with only one stove, the two huddle together for warmth. Startled by a sudden bolt of lightning, Riri clings to Takuto. At that moment, Riri's breasts press against his body, and Takuto, aroused by her erotic scent, gazes at her. "...No..." "Yes..." "...I said no..." "I know!" Takuto forcibly steals her lips, and though she resists, Riri finds herself unable to push him away. Their bodies overlap, and Takuto's cock slides inside Riri. Forgetting their positions and losing themselves to desire, they repeatedly fuck until morning. Then, the two return to their daily lives as if nothing had happened.
