Mirei lives with her husband and father-in-law. One day, while cooking, she accidentally cuts her finger. Her father-in-law notices and asks, "Are you okay?" then gently licks her injured fingertip. The next day, while her husband is away, her father-in-law approaches again, asking, "Is your finger better?" and once more starts licking it. From that point on, her father-in-law begins licking her fingers every day, and Mirei misses the chance to stop him. His actions gradually escalate, consuming her body completely. One day, as Mirei is practicing yoga, her father-in-law quietly appears and starts reading a book nearby. Unbothered, Mirei continues her routine, her body slowly glistening with sweat. Her father-in-law watches her with a sly grin. Soon, he moves closer and starts licking her feet despite her protests. Then, as if savoring her sweaty body, he begins licking her all over. Mirei gradually surrenders to the pleasure, losing herself in a sensation of release.
