GVG-080 The Tale Of An Uncle And His Son Who Couldn't Avoid Getting Rock Hard Seeing His Niece After She Has Grown Up Into A Mature Young Woman Ruka Kanae

An uncle and his son 'Daichi' come to visit 'Ruka' for the first time in several years. That night, Ruka's uncle is astounded when he invites her to the bath with Daichi. That's because her niece, who she thought was a child, had grown into the body of an adult woman. My uncle, who had a long life without a daughter-in-law in a father-son family, saw her naked and couldn't control her libido.
