A Weak Little Fox Was Taken in by a Yandere Older Sister

I, a nine-tailed fox who has cultivated for a thousand years, was ambushed during my tribulation! All my cultivation was lost, and I was forced back to my original form! Even more humiliating—I was picked up by a human girl like a stray dog! She rubbed my belly, pinched my ears, and even carried me into the bathroom to "wash together"! At night, she always held me so tightly she could hardly breathe! I endured the humiliation and tried to escape by reverting to human form. But she chained my ankles with silver chains and dragged me back to the bed. She stroked my fox ears and chuckled, "Since you found me, I'm mine." "Little fox, where do you want to go?" Now she makes me transform into my ears and tail every day so she can pet them. Otherwise, she'll take away my dried fish!
