Inside the bath, nipple mom Tomoko gently and carefully cleans her good-for-nothing son's cock with her mouth. When her son involuntarily starts to pee, she catches his urine in her mouth in a depraved act. Her sensitive, long, pitch-black nipples grow increasingly aroused from her son's handjob. Even when her nipples are sucked and tightly bitten to the point of being drawn in, her excitement doesn't stop. She reaches climax through a gentle, meticulous handjob. Her satisfied expression clearly shows her pleasure.
