When they got inside, Jon closed the door and said, "Actually, Karyn has a test she needs help with also. Why don't you help her, first?"
"But I need your help with that," Karyn objected.
"I think you can make do with her," he asserted.
"I can't!"
"Well, what were you going to do, then, that she can't help you?"
"I..." Here, she looked down, and her voice dropped almost to a whisper, "I need to give you a blowjob."
"Oh," he said, "Is that all? Well, then I guess Sarah can help you in a different way. In the meantime, help her undress."
"What? She doesn't need help undressing," Karyn objected.
"Yes, she does. In fact, I want to watch you undress her. And make it as sexy as possible. I always thought stripping should be a full-contact sport. Sarah, feel free to play with her as she's doing it."
Jon sat at his desk, and put his hand on the stone while watching them. He quietly muttered, "I wish I had another, identical body stocking sitting on my desk for Sarah to wear. I also wish that Karyn and Sarah find each other very sexy, and love to show off themselves and each other to me."
As he finished saying that, the show he was watching went from awkwardly intriguing to mind-blowingly arousing, as they really got into each other, as well as the show they were putting on.
