Someone had picked up the paper and started reading it! The voice was her brother Benny, and as she opened the door she heard him finish the wish and take the note off the door, mumbling about how stupid it was. How little he knew!
Benny looked back as he walked down the hall, and saw his sister looking at him with her erect cock sticking out in front of her and pushing her dress up. She must have been playing with it again. He snorted in disgust; she played with her cock more than he played with his. More than once he had heard their mom complaining about how she played with it instead of putting it in her. As he walked, Benny felt a peculiar sensation. Hair was rubbing against his underwear.
Benny turned on the stove and let the paper burn, perfectly, despite having never used it or seeing anyone use it. Suddenly he felt a strong urge to pee, and ran into the bathroom. He doubted he could hold it in for long. Dropping his pants in front of the toilet (a personal habit; the zipper got stuck too much), he let loose and realized too late that he had nothing to hold onto. Pee dribbled down his legs and onto his pants, and he screamed as he realized why. His cock had disappeared! A large slit was in its place, with a patch of blond hair above it. Mom was blonde.
That dumb wish must have come true! Benny quickly sat down, but it was too late. His pants and underwear were wet, and he realized, he was still wet. Grabbing a piece of toilet paper, he gingerly picked at his new genitals, as if it would reach out and bite his hand, until he was dry. He sat on the toilet, legs spread, just staring at it. It occurred to him, that if he had mom's... pussy, then his mom had HIS parts! His suspicion was confirmed when his mom came into the bathroom, whose door he had left open.
"Are you done, dear?" He nodded and jumped off the toilet, watching her pull out a small penis and sack he recognized very well, as his own! She held it between two fingers, making it seem even smaller, and he felt momentarily ashamed at it being so much smaller than his sister's... which was probably actually his dad's! She read the wish too! He just watched his mom, wondering how to reverse the wish...
