Yuna, a setter who excels in her club, works hard as the team's backbone despite her short stature. After practice ends, she parts ways with her friends and finds herself alone—when a man suddenly appears, targeting her. Before she realizes it, a man with an erect penis stands right in front of her. Her wide-open eyes widen in terror, her plump lips trembling. A vibrator is pressed against her hairless pussy, and she involuntarily urinates from overwhelming sensation. Helpless, she's cruelly toyed with in this vulnerable state.
