My sister's huge breasts are better seen than heard. Apr. 2015 Amaterasu Yoshika H cup 98cm R18-296

The good-for-nothing older brother, in order to pay off his debts, takes a liking to his younger sister, Yoshika Amatori, with her large breasts. Yoshika thinks it's a one-time thing, and that holding a small photo session to collect admission fees shouldn't be a problem. However, all the guests who come are lustful and want to have sex with her, so of course, it ends up as a gang rape.
