On a summer business trip to the countryside, an unexpected shared room arrangement is made. In a run-down hot spring inn, the broken air conditioner makes the room hot and humid. Alone together in the room are a department chief and a female coworker. A normally quiet employee unexpectedly reveals her aggressive side in this situation. Her intense gaze and sweet whispers shake his rationality. Enjoying the chief's tense body, she stimulates him with her long tongue and tempts him to climax with her skilled hip movements. She teasingly grinds her hips, squeezing out every drop of his semen. The chief, completely entranced, murmurs, "You're so cute... I love you... Please... Come inside me..."—already too far gone to turn back.
