Ichika, a member of the naginata club with a naughty personality, becomes increasingly aroused as she indulges in erotic fantasies and masturbation. The man she falls for is an AV enthusiast who turns her body into his toy during her teaching internship, a pervert who gets excited even when she receives cum in her mouth. Her naginata master also has sex with her in the gym, riding her in cowgirl position and facialing her, while her childhood friend jerks off in front of her and has sex with her while whispering lewd lines. Even during training camp, her master teases her in the bath and tortures her pussy with a vibrator in embarrassing poses—Ichika's cunt is always destined to be targeted.
