Receiving the news that his cousin had just come from the countryside to take the university entrance exam, Momojiri Kanon was very happy because he finally got to see his childhood friend again after a long time of not being in contact with her. She was very attentive and enthusiastic when he was there, doing everything to make him feel the most satisfied, including bathing together - one of the unforgettable memories of their childhood. But time has passed, now he has become a teenager, at an age where his psychology and physiology are strongly developed, so just a sensitive factor like bathing together just now will make him lose his mind. Plus the fact that his lustful cousin is always naked and making extremely seductive inviting movements, unwanted things will definitely happen.
