My Muscle Slave [v1.8] [FMG-Smug]

February 2, 2026F95

In this dark and sensual tale, a father and son buy a muscular slave girl from the market to help with farm work. However, as she begins working on the fields, she starts to grow more muscles at an alarming rate.
The girl’s transformation sparks both fascination and lust in her owners, but also raises questions about their morality and desire for control. As she becomes increasingly powerful and alluring, they must confront the consequences of owning another human being and the blurring of lines between master and servant.
Will the father and son succumb to their desires or find a way to tame the beast that is growing within the muscle slave girl?
