On her way home from shopping, Yumi is hit by an intense urge to urinate. Even though her house is only a short distance away, she gets caught at a railroad crossing at this very moment. She can't take it anymore! She runs to a neighbor's house and rings the doorbell, but no one comes out. She glances to the side and sees a garden where she can hide from prying eyes. Feeling embarrassed, Yumi takes off her panties and urinates on the spot. However, behind her, a man is standing with a grin on his face, holding a cell phone. The man asks for her body in exchange for her silence.
