A story of Sara, an exceptionally beautiful female college student with massive, voluptuous breasts, approached on the street and challenged to have sex with a non-Japanese big-dicked AV actor. She agrees to the encounter, attempting to endure orgasm using her willpower in exchange for a huge reward of 1 million yen—testing herself against the actor famed for making porn stars climax repeatedly. In the end, her hips violently jerk and spasm, her body arching like a shrimp as she nearly passes out from intense pleasure, resulting in the actor's complete victory. Though she doesn't win the 1 million yen, her blissful expression—experiencing the most pleasurable sex she's ever had for the first time—leaves her satisfied and content.
