Blackmailed for Lust (Erotica)

Three years ago, Dahlia and Carter split up due to a misunderstanding. Now, they meet again: she's a waitress, and he's a guest at her club. This time, Carter forces Dahlia to sign a contract making her his slave, turning her life upside down. Despite this, their old love starts to rekindle. In the end, who really controls whom-does the owner bind the slave, or does the slave tame the owner?
