One day, my nephew, Myoka, suddenly returns home as a transsexual. At first glance, her face and body only look like a girl's, but she actually has a nice penis attached to her! However, her father and her brother are surprised when they see her again for the first time in a long time, and they attack her even though they know she is no good... Even though she is a transsexual, her body is full of the libido of an adolescent.
