Mermaid Has Fallen

My brother went fishing and brought back a beautiful shark girl. The woman's skin was snow-white, her upper body was naked, and her lower body was sparkling with light blue fish scales. "Yaoyao, after you skin her, can my brother make you a fairy skirt?" But at night, I saw my brother forcing the mermaid to kneel in front of him, making strange and joyful sounds. Until later, I suddenly discovered that I also had scales growing on my body.
