This was truly a masterpiece. The large butt and the panty flashes of sister Ichika catch the eye, while her personality shines in practical scenes one after another. In particular, the provocative angles from the top of the stairs and her sitting cross-legged on the sofa were mesmerizing. Furthermore, the choice of underwear, such as the elegant white full-back panty and the extremely small bloomers, was excellent, providing great visual satisfaction. The fresh setting of a gal-style high school girl also highlighted her charm. However, I felt a slight dissatisfaction due to the absence of the doggy style scene featured on the cover. Nevertheless, Matsumoto Ichika's eroticism is of national treasure level, and her straightforward expression of passion towards her brother was breathtaking. The situation setups, like the riding position from a hip perspective, were exquisitely crafted, making it a work that begs to be revisited.
