Sisters’ Slave (2019)

One day, two ordinary sisters, Ah-rong and Da-rong, receive a peculiar birthday gift from their mother: two male servants named Chi-chi and Po-po. Bound by a childhood contract, these men exist solely to serve the sisters and fulfill their every desire. Da-rong, the younger sister, treats them like objects, commanding them to perform all sorts of menial tasks without hesitation. In contrast, Ah-rong, the older sister, feels pity for them. The sisters often bicker over their differing views. But the dynamic shifts when the sisters begin ordering the servants to fulfill their sexual fantasies.
