Ever since the day she seduced her son out of frustration, Mari (Mari Kuroki) could no longer be a normal mother. She knows it's a crazy relationship. But her son's cock is stronger, more impressive, and more virile than her husband's... Mari couldn't stop her desire from escalating. And finally, she clung to her son right after he ejaculated inside her vagina and screamed, "Keep going!" She begged her son to keep ejaculating inside her without pulling out.
