Suddenly, the bathroom door flew open and his Goth sister Zoe stood in the doorway, staring at Jon's penis, which he held in his hands.
She immediately charged over to him, pulled down her pants and panties, and impaled herself to the root on his cock.
She bounced slowly up and down, milking his cock with her pussy, working it for all she was worth. She leaned over and whispered in his ear. "Does that feel goooood?"
Jon sat back. It was ecstasy. "Yeah," he breathed.
This definitely was unpredictable and sexually exciting. Who ever thought that Zoe would feel this way about her brother?
