Incest: The son comes back is a transsexual, and when his son sees his big dick, his mother and sister...

My son runs away from home and comes back as a transsexual. His mother and sister are ecstasy. His appearance is a woman, but his genitals are huge and his mother is hungry for men, and his son forces him to have sex, and his sister ends up sneaking up on his younger brother at night! This is a story of incest between a slightly unusual parent and child.
