Bullied By My Alpha Stepbrother

"I'm about to cum in your smart little mouth and you're going to swallow all of it. Do you understand?"
He didn't let me answer, holding my head in place as his cum filled my mouth. He waited until I had swallowed every drop before he released me and I fell to the bed, sobbing.
Zipping himself up, he stalked to the door, then paused and turned to smirk at me. "Don't even bother to tell anyone about this. Or you and your mother will suffer. And get ready, because this is just the beginning."
