Kazuya is a high school student. He moved to move to a boarding school because his parents went abroad for business, and they sold their house before leaving for Japan. But, his school does not have a male dormitory so he lives in a female dormitory. One day, he secretly peeked into the UKS school that is undergoing regular physical examinations, and he was surprised to see their exotic breasts. He made an oath to get their bodies and breasts.
