OPPAI's work 'Ultra Huge Breasts Q-cup: Himari Onee-san' is highlighted by the swinging huge breasts and breastfeeding handjob. It can be said to be an irresistible work for fans who are fascinated by Himari Onee-san's slutty character. While Himari-chan's perversion stands out, there are also many expectations for creampie scenes, and her role as a big sister is highly praised.
