Receiving news that her cousin has come to visit after taking university entrance exams, Kururigi Aoi was very excited because she could finally meet the cousin she played with since childhood after a long period of no contact.
She was very attentive and enthusiastic while he was there, doing everything to make him feel as comfortable as possible, including bathing together - one of their unforgettable childhood memories.
But time has passed, and now he has grown into a teenager, at an age where psychological and physiological changes are intense, so just a sensitive trigger like their recent shared bath could lead him to lose his reasoning.
Moreover, with his cousin always being naked and doing incredibly tempting inviting moves, unwanted things are bound to happen.
