Since her husband died, her mother, Sakura, has raised her son Masami single-handedly. Masami grew up to be a filial son who put up with playing and working part-time because of the tight family budget. But even so, a boy of his age... Ever since he happened to see Sakura's plump nakedness in the dressing room, he couldn't hide his interest in women. When Sakura learns of her son's secret desire, she will at least show her nakedness and teach her sex. Beginning with her gentle kiss, paizuri that wraps her son's cock with big boobs, and raw insertion... Her mother's special reward would develop the two into a forbidden relationship.
