Iori-chan is the picture of purity and kindness, resembling a class president—the kind of girl who seems far removed from anything sexual. Yet, there's an oddly captivating allure as she meticulously licks a man's anus. Through this act, she gradually moistens his most intimate area, leaving his underwear soaked as she brings him to an intensely sensitive state. In this process, her gentleness intertwines with a seductive charm, unfolding an entirely new erotic world.
