A slender and beautiful married woman, Ai. Once a month, when she sees a man, she seems to have an irresistible urge to lick his body. I don't know why. However, this time the desire was irresistible. Licking her husband's body isn't particularly problematic, but she licks the contractor who came to inspect the electrical equipment, and also her husband's brother, who she met for the first time in a while.
