Jon and Someone Else

"Hello?" a voice asked. "Is anyone in here?" Mikey braced himself, but was relieved when it turned out to be Jon. Jon wasn't of the opposite gender, so Mikey's wish wouldn't force them to swap. However, the person following Jon into the room *was* of the opposite gender. "Hey, Mikey," Jon said. "I was wondering if you wanted to go see a movie with us later, after school." Mikey looked at the *female* person walking into the room with his brother and suddenly felt the changes occurring in his pants.
