On a business trip to Fukuoka, after a dinner meeting following negotiations, an unexpected room shortage leaves them with no choice but shared accommodation. Her new wife, a confident and beautiful female superior, catches the eye of a male coworker who instantly falls for her—and quickly acts on his feelings. Trapped in a private room, the man can no longer suppress his desire and moves aggressively toward her. What follows is an insatiable night of relentless sex, climaxing in ten ejaculations. "I can go as many times as needed with Director Momo Sakura," the male employee boasts with a grin. Initially resisting, she gradually gives in, then becomes completely absorbed in the pleasure. The stunning, big-breasted boss is repeatedly brought to orgasm throughout the night, overwhelmed by sensation, whispering, "Hey, don't tell anyone about this..." The intense intimacy and her transformation are key highlights. This work delivers a raw, realistic portrayal of a single night ruled entirely by desire.
