Upon meeting the lewd and slutty Akari Niimura, Yuna Kitano, with her glamorous big tits, is confused by her first lesbian experience, saying, "I'm so nervous!" She confesses her masochistic tendencies, saying, "I get excited when I'm choked and it hurts," and her words ignite Akari Niimura's sadistic spirit. As soon as she kisses Akari, Niimura starts choking her and verbally abusing her, Yuna Kitano's expression melts as she writhes in agony. Eventually, she is so moved by the lesbian bondage and choking tribadism that she bursts into tears.
