Rebecca takes issue about it

"No way am I leaving you two in the same room while you're like..." Rebecca trailed off as she gestured to Alison's body, "...This."

"And what do you want to do about it? Also, don't forget about the shower situation!" Walter mentioned. Rebecca thought about how, due to their terrible boiler, they had to take showers quickly, one after the other. Walter used to separate the girls and Jacob being naked in the same room at the same time, but now, with him like this. She shuddered at the thought of her son getting hard at his own father!

"No! I'll be the buffer now. At least until you're back to normal." Rebecca stated.

Just then, Walter AKA Alison did something unexpected as she quickly crossed the few steps to her son, knelt down and pulled down his pants, revealing his son's enormous cock, stiff as a baton, sticking out horizontally into the air.

"Put that away!" Rebecca yelled as she turned around and shielded her's and Sandra's eyes, "Sandra, why don't you go. Leave this conversation to your father and I?"

"Sure mum." Sandra said, gladly leaving the madness in the room. Rebecca slowly turned around to see if Walter had put it away, only to see the engorged organ of her son twitch towards Alison's body.
