Long-haired, fair-skinned, slender beautiful girl Chiaki. She practices classical ballet and has a flexible body. A well-proportioned face, small breasts, a height of 162 cm with a supple waist, and beautifully shaped hips. Such a natural beauty of a younger sister engages in a forbidden relationship with her perverted brother while their parents are away! Her ultra-sensitive body trembles as she has intense, deep penetration sex with her big-dicked brother!
