At Makino Reina's home lives Mio Shinozaki, a perverted butter dog who licks her body all over. Today, her legs are tired, so she decides to have Mio pamper her prized beautiful legs with her tongue. Mio presses her mistress's toes against her own crotch while passionately licking her feet, slowly arousing her owner with her sweet, skillful tongue. It's a warm, intimate moment, like a pet tenderly soothing her master. Mio's gentle yet bold actions bring a new allure to their everyday life.
