While Jon's mother Rebecca was in her bedroom with Sarah's mother Alexandra, Jon was in his own bedroom with Sarah.
Truth be told, this was always a fantasy for him. Yes, Sarah was a total bitch and this is something she deserved, but she was also so incredibly hot. Jon figured that he couldn't be the only one who thought about Sarah this way.
She was kneeling on the floor, bowing her head like a servant, as Jon approached her.
"Sarah?" he asked.
She looked up at him. "Yes, Master? What is your command?"
Jon smiled. He was going to really enjoy this.
