Brother Rapes Innocent Sister Who Doesn't Know How to Fuck

Freshly returned from Tokyo after years abroad is Mary Tachibana. With her parents away on business trips back home to their family residence in Vietnam (or implied domestic setting), she is greeted by no one but her younger brother. What Takashi quickly discovers is that his sister has blossomed into an incredibly seductive woman! Unable to tear his gaze away from Mary's stunning curves and hot body, Takashi observes that his sister possesses a wonderfully naive and trusting nature. Seizing this opportunity for mischief—and desire—he hatches a plan to trick Mary into letting him take advantage of her innocence. He fabricates a convincing lie: he claims that if a woman doesn't have sex within three years, her hymen will close up completely, effectively turning her back into a virgin—a phenomenon known as 'second virginity.' Fearing the loss of that pristine first-time sensation, Mary eagerly asks Takashi to perform this supposed checkup. And with all the time he needs, Takashi executes his wicked scheme against his unsuspecting, beautiful older sister! This steamy encounter promises raw passion and sweet betrayal in this must-watch familial scene.
