"Of course, I am," said Zoe. "Being your sex slave sounds great."
"You want to fuck me as often as possible," said Jon.
Zoe immediately hiked up her skirt, pulled down her panties, faced away from him and bent over, exposing her shaved pussy towards Jon. "Come on, Jon," she begged. "I'm burning up for you."
Jon pulled down his pants and began to shove his cock into his sister's waiting pussy. Both siblings moaned as Zoe bucked her hips in time with Jon's thrusts. Jon had little experience with sex, but this was definately the best experience he ever had.
Suddenly, the door to Zoe's room opened.
