The black man who came for a homestay is intriguing to the host's younger sister, older sister, and mother. The younger sister becomes interested in his big dick, the older sister sees his erect flaccid dick, and both sisters become curious about the big dick; they feel overwhelmed by its size when it enters them. A Japanese man couldn't imagine such an oversized dick, making them dizzy with pleasure as they enjoy a sister sandwich, and even involving their mother in a forbidden three-way!
