Charming girl Tsuna in a sailor uniform is held captive and subjected to electric stimulation. With fingers inserted into her vagina and her clit stimulated, she squirts like a fountain—her body highly sensitive. Through finger play, rotor, and vibrator sessions, she is brought to 43 squirting orgasms. Thrust after intense thrust pushes her to the brink of collapse. With innocent, pure eyes, Tsuna spends the entire day engulfed in the pleasure of electric currents.
