Sarah's Mom Interrupts

As Jon watched the three girls continue to kiss and feel up each other's naked bodies, he heard a knock coming from Sarah's bedroom door. Wondering who it was, he opened it, revealing Sarah's mom. He had only seen her a couple of times at the high school, so he at least knew what she looked like. "Oh. Hi, Jon," she said. "Is Sarah in there?" Behind him, Jon heard the three girls moaning as they continued to make out with each other. Did Sarah's mom *know* about Jon's "special" relationships in this reality? If he had the wishing stone with him, he'd just wish her away. But he didn't. It was still back in his bedroom. She pushed on the door a little. "What's going on in there?" she asked. Jon froze up, unsure of what to say.
