Maki, the mother of his best friend, has known him since adolescence, and for the past several years they have secretly been fuck buddies. Whenever he visits, she welcomes him warmly and hints that her child is away, inviting him to use their brief time alone. He is captivated by the maturity, maternal warmth, and confidence women his age cannot offer, so they fuck repeatedly before his friend returns. Later Maki unexpectedly calls and offers to clean his room. Visiting him for the first time, she admits she missed him too much to stay away, climbs on top in a burst of pent-up lust, and drains every last drop from him. Two scenarios—one tender and indulgent, the other aggressively seductive—deliver 100 minutes of nonstop sex in every position, with creampies throughout.
