Ayame, a visiting caregiver, spends her days working alongside her husband. One day, she visits the home of elderly Mr. Ozawa alone. While tending to him, she leans in to wipe his back when suddenly he grabs her tightly, forcibly spreads her legs, and begins licking her pussy with lewd intent. Begging her just this once, he pleads for her to fulfill his desire—and she gives in. After that, Mr. Ozawa repeatedly seeks out Ayame’s pussy whenever he gets the chance. Gradually, Ayame finds herself emotionally unsettled by their encounters, sensing a deep, inner transformation taking hold.
