After watching Sakakibara Moe's new work, I can say this is a masterpiece that pushes the sister character to its limits. The premise of suddenly gaining the world's cutest sister, who becomes overly affectionate and turns into a痴女, enhances the immersion typical of subjective works. From the opening line, "Nice to meet you from today, big brother!" Moe-chan's innocent yet seductive charm explodes onto the screen. In scenes of fellatio and nipple licking, her direct gaze at the camera is irresistible, and her陶醉 expression while being teased over her panties is adorable. Her喘息 during penetration perfectly matches the line, "Cum all over with Moe," captivating the viewer. However, as a subjective work, it lacks scenes where Moe-chan herself has her nipples or私处 licked, missing the chance to see her climax during foreplay, which feels a bit lacking. This also heightens anticipation for future痴女 or soft rape works. Moe-chan's breasts are not just large but voluminous, swaying beautifully in a circular motion during cowgirl positions. This piece is recommended not just for big-breast lovers but for those who appreciate beautiful breasts. Yet, the sister premise's setup is slightly jarring, hindering immersion, which is a pity. Overall, Moe-chan's cute, beautiful, and sexy charm is in full display, and the combination of sister character and subjective work is highly萌える. I eagerly await future developments in her works.
