My Stepson, My Lover

To investigate my family's downfall, I moved in with a man even older than my father.
Unexpectedly, I discovered his son was Kevin - my ex-boyfriend of many years.
While his father slept inside, Kevin pinned me against the door, covered my mouth, and forcefully penetrated me.
"You break up with me and end up with an old man? Can he make you climax like I can?" he whispered in my ear.
"What should I call you now? Stepmother?"
