Returning home from shopping, Yumi is suddenly overwhelmed by an urgent need to pee. As she nears her house, she realizes there's no avoiding it. Desperate and with no public restrooms in sight, she rushes to a nearby house and rings the doorbell, but no one answers. Panicking, she scans her surroundings and notices the neighboring yard hidden from view. Fearing embarrassment, she pulls down her panties and begins to urinate right there. Unbeknownst to her, a man stands behind, smirking as he films her on his phone. Quietly watching her every move, he soon approaches, drawn by desire. Tense and anxious, how will she respond?
