Chiyoko is a motherly figure to the young part-timers at the family restaurant where she works. But even at seventy, she's still active as a woman. Her true self is a predator who seeks adventure with young men. One day, Chiyoko is assigned to train a new employee. The training takes place in the empty store after closing. Seeing her chance, Chiyoko uses the opportunity to guide him and press her body against his. The intense body contact causes the new employee to reflexively get an erection.
