When Naomi gets bored during winter break, her slightly airheaded personality shines through—so much so that she even enjoys sex using a vibrator right in the middle of class. Kanae, cute with her loli face, has a particular quirk: she won't do it unless she's fully aroused, fiercely maintaining her pride as a dominant, no-nonsense queen. Meanwhile, Yuu is so horny her mind is filled entirely with cock, constantly emphasizing her strong desire to suck one every single day. The unique charms of these three girls intertwine, promising an intensely erotic experience.
