Obsessed Daddy (Forbidden Daddies #1)

My sister needed a spy, someone to dig up the dirt on her ex.
Now I’m in his bed, calling him Daddy, and pretending I’m not losing control.
I shouldn’t want him.
He’s older, dominant, obsessive, and completely off‑limits.
But the moment he calls me a good girl, every line I swore I wouldn’t cross disappears.
I came to ruin his life.
Now I'm begging he ruins me.
