Grandmother Matsuino Reiko, who lives with her son and grandson, is an overly sex-driven carnivorous old lady. Every morning, she begs her son for his dick and engages in incestuous sex with him, culminating in internal ejaculation. When her son goes on a business trip, her sexual desires turn towards her grandson… She lewdly gropes her grandson's young body, uses anal licking and handjobs to make his dick hard, and then performs intense paizuri and deep throat blowjobs until he ejaculates in her mouth! Still not satisfied, the grandmother attacks her grandson again, riding him with vigorous hip movements in a reverse cowgirl position and achieving internal ejaculation! The debauched grandmother's three-generation incest!
