Synopsis:
In Book 4...
Chris and Sarah’s bond deepens into something darker, tender, and dangerously irresistible. Now unbound, Sarah finds herself yielding, not from fear, but from a growing desire to please Chris, whose quiet dominance seeps under her skin.
As Amber’s volatility and Heather’s calm scrutiny close in, Sarah’s world narrows to the woman she can’t escape. Every touch, every command, draws her further into Chris’s orbit, blurring the line between captivity and craving. Book 4 pushes their dynamic into irresistible, psychological intimacy, until Sarah realizes she no longer wants to break free.
This is the fourth book in the lesbian book series " I'm broke, can I pay for the room with my body? "
