Six months ago, Reiko's sex life came to a halt due to her husband's erectile dysfunction, and her sexual frustration had finally reached its limit. One day, she caught her son masturbating in his room—and unable to restrain herself, she boldly approached him. "If you're going to cum from jerking off, then just come inside Mommy!" she passionately seduced him. With his naturally insatiable stamina, her son began satisfying her deep longing. After that, Reiko couldn't control herself anymore, demanding three consecutive creampie rounds from her son without letting him pull out. The forbidden relationship between mother and son has ignited an unending passion that still rages on.
