Under the scorching summer sky, MISAKI heads to the pool alone. The coach hasn't arrived yet. She begins with a slow, thorough stretching routine. Her tight-fitting competitive swimsuit hugs every curve of her body, intensifying the pleasurable sensation as it presses against her skin. Her long, slender legs stretch wide, muscles extending gracefully—her movements are mesmerizing, stirring deep emotion. Just then, the coach arrives. She feels his burning gaze, and though their conversation seems ordinary, an excited tension fills the air. As her body grows warmer, her hand instinctively drifts toward her private area. Guided by the coach's intense stare, MISAKI gradually transforms into a lustful woman. Just as she attempts to resume practice, a sudden cramp strikes her leg.
