Her sister is cute and has big breasts, which keeps enticing fans' hearts racing. In the story, her sister Miharu boldly approaches during wake-up moments and while taking a bath, even seizing the opportunity while her sister is about to go out. Despite being a clothed SEX scene, her voluptuous body stands out, especially in the bath scene where her cute gestures captivate the viewer. Her skillful way of being needy and a soft S perfectly aligns, and while the overall story development is solid, the structure keeps the viewer engaged without boredom, which is its charm. The tempting voice saying 'big brother' makes one irresistibly infatuated. Furthermore, the camera work is exquisite, particularly emphasizing the bouncing of her breasts, which is sure to excite. I was thoroughly enchanted by Miharu-chan, who exudes that erotic and cute devilishness throughout this work; I would have loved to see her in the nude, but even so, it was incredibly enjoyable. Even if you’re not a fan of the sister genre, this work might awaken something in you. I have high hopes for her future endeavors.
