The adaptation of the mother-son erotic doujinshi from the circle Golden Bazooka! Miyuki, an elite housewife supporting her high-achieving husband, is a mother of one and lives a privileged life. Her only problem is her son's explosive libido—his constant sexual urges have left him at the bottom of his class academically. Fed up with his behavior, Miyuki rashly promises him that she'll satisfy his sexual needs if he earns first place on his next test. However, she never expects he'll actually achieve first place when motivated... Now Miyuki is forced to endure her pubescent, insatiable son's endless sexual demands, daily extracting his foul-smelling semen. Just when the husband is away on a business trip, the son begs on his knees for sex. Despite her feminine instincts awakening from daily sexual service, will this responsible mother with huge breasts and a massive ass confront her son's rock-hard cock?
