"I want you."
I grab my sister's arm and hold her tight.
"I love you, sister. You feel the same, right?"
I breathe the words close into her ear, her resisting body pinned.
"Every night you masturbate thinking of me. I can hear you."

"No! You've been listening? That, that's not what..."

And in an act I regret, I push her down onto the sofa.

A brother and sister cross the line into reckless, wild sexual lust that only escalates with each passing day.
