Sarah woke up at the sound of snoring. Biff didn't snore that much, but it seems that with her mother's body, somehow he did. "Biff?" she said. "Or should I call you Mom? I can hear you snoring."
"Come on," replied Biff. "We need some rest. I need some rest, because tomorrow I have to figure out what happened. We can't stay like this."
"We don't know how long it lasts," said Sarah. "Maybe it's like a werewolf. It lasts when the moon's up. Um, do you know the phase of the moon?"
"No, I don't. Let me go and check."
"I wouldn't advise it," said Sarah. "I don't think we can see it from the window. Do you want to go outside as Mom? What would people think?"
"Nothing bad about me," said Biff. "And what if someone catches me out here? It'll only be a second." He got up and opened the door a crack. Satisfied that nobody was awake, he then slowly pushed it open until there was a big enough space for him to squeeze through, though his tits brushed against the doorframe.
Biff made it to the front door and went outside to look for the moon. He saw it on the horizon... it was a half moon and had just risen. So much for that idea.
Meanwhile, Jon had decided to go outside too, to see who the werecreature was. His eyes came upon an older woman in a nightgown. Sarah's mother... wait, he recognized it. It was the werecreature!"
At least I'm safe, he thought. She's not going to attack. But I wanted the affliction to spread in an appropriate way corresponding to what the creature is. What could be the appropriate way to spread an affliction of being someone's mother?
