[Milkdou Shoukai (Milk Studio)] My Son's Star Is His Own Mother

A former teen model whose super big tits made her a gravure star has buried that past behind married life, until her own son uncovers her secret and demands she show him everything. To keep him quiet about it and about what follows, she lets him undress her, worships her huge breasts and lets him take her right there, gasping that her young son puts his father to shame. What begins as a bargain for silence soon becomes obsession, as the boy claims her as his alone and the cheating mother willingly sinks into a private world where only the two of them exist.
