Suddenly, Karyn felt something pressing against the inside of her jeans. She looked down and nearly fainted, seeing a very familiar bulge that should have been in a boy's pants and not her own.
Jon's jeans seemed to loosen a bit and when he looked down, he realized why. His genitals were gone! But, of course, they weren't really gone. Karyn had them. And Jon had her vagina.

Jon snatched the random swapper device out of her hand. "I told you. It's random. You can't swap back."
Karyn pulled down her pants and saw the bulge in her panties. She felt like getting sick. "Then how do we fix this?"
