Charlotte, a high school girl, finds solace in her fantasies, masturbating to release her pent-up desires. The anime opens with her in the throes of self-pleasure, her body writhing, fingers delving deep into her wet pussy. Her mind drifts to her classmate, Yuu, and their shared moments. She imagines him touching her, fucking her hard, his cock sliding in and out of her tight cunt. The scene builds to a crescendo, Charlotte's moans filling the room as she comes undone, her body convulsing with pleasure.
