Abnormal Ecstasy: Extreme choking fetish play returns for its fourth installment. Childhood friends, high school girls Hikaru and Aki, are relaxing together in a room when Aki, influenced by videos she saw online, suggests trying choking play. Obliging her best friend's request, Hikaru agrees to let Aki use gloves to strangle her. Aki begins tightening various gloves around Hikaru's neck, gradually pushing her into a state of asphyxiation. Hikaru's eyes roll back, foam forms at her mouth, her body convulses violently, and she loses consciousness. Witnessing this, Aki becomes increasingly aroused and proceeds to fondle Hikaru's breasts and groin while she's unconscious. Surprisingly, Hikaru's body responds, rippling with involuntary spasms. Aki then gives Hikaru a deep, passionate kiss right in her rolled-back eyes, drawing her deeper into the sensation. When Hikaru regains consciousness, she finds herself awakened to the pleasure of choking, and willingly ascends into ecstasy, surrendering completely to Aki's strangulation play.
