Mina-chan was pinned down by Aimi-chan and Maimi-chan, trapped in a hell of electric massage and tickling. Though she finally escaped that torment, Mina-chan looked unsatisfied and asked Aimi-chan, "Didn't Maimi-chan get the electric massage before? It's your turn now!" demanding revenge. Aimi-chan immediately protested, "No, no, no, that's not right! It was Maimi just now!" but before she could finish, Mina-chan grabbed Maimi-chan's legs, turning her into the target of retaliation. Aimi-chan's actions are terrifying. Maimi-chan is extremely sensitive to electric massage and has a fragile, timid personality. Once the electric massage begins, Mina-chan pins down Maimi-chan's upper body, further cornering her. Maimi-chan can no longer escape this hell of electric shocks and tickling. She is played with repeatedly through electric massage and tickling, climaxing over and over again. Her sensitivity goes haywire, cumming double-digit times, with the intensity peaking to uncontrollable levels. At times, she orgasms within just ten seconds of the massage starting, arching her back like a shrimp and climaxing repeatedly. Her screams echo throughout the classroom as she bursts into tears, yet Aimi-chan and Mina-chan show no mercy—the torment continues relentlessly.
