When I returned to my hometown for the summer vacation after a long time, to my surprise, my older sister and younger sisters had all become gyarus! My older sister's exposure was extreme, and my cute younger sister started to belittle me, a virgin. Moreover, all of my sisters seem to be targeting my body for some reason!? Hey! No penetration allowed! We're siblings! A seven-day battle was about to begin between me, a virgin, and my four gyaru sisters, all at the peak of their allure.
