Well, he was horny as hell at the time and not really thinking clearly as his very erect penis showed. Doing what teenage boys do best when they have the chance he finished himself off and then laid down on his bed to ponder.
"I wonder why I am wearing the same clothes as Lira in this new reality. This is going to be an odd monnnnnnth" he slurred the last word as he realized that he had forgotten to add a time limit to the wish. "Oh shit."
He worried for a few minutes before deciding to just roll with it for now. He intended to put a month time limit on it so he was going to spend at least a month like this, and anyway everyone would think it normal. He would figure something out later. Now however he wanted to explore a bit and see what changed.
He got up and first went to the bathroom to properly clean himself up, but while he did he couldn't help but feel uncomfortable doing it. When he was satisfied he felt a bit less in touch with himself, but shook it off as just being nervous and didn't give it a second thought. He looked at himself in the mirror, mussed up his hair and left the bathroom.
Next he went downstairs and stopped on the bottom step when he saw his mother in the living room completely nude. She was sitting on the couch watching TV. He noticed a definite smell in the room and realized that it was coming from his mom. Her hair was a shambles, like she hadn't washed or brushed it for a long time, and there were distinct areas on her skin where dirt had accumulated.
"Oh, hi honey. What are you up to?" She didn't comment on his nakedness, and with her being naked the wish must have made everyone nudists like Lira. Worse, he had a sinking feeling that no one was bathing either.
