From inside Zoe's shirt Jon couldn't see what was happening for the rest of the day but knew from what he could hear that she spent the day at school then hung out with her friends. When he could see again he noticed that they was in the bathroom in their house.
"A shower, she must be taking a shower! I won't have to be her bra anymore once she takes me off. Maybe I'll turn back." Jon was so excited that he almost didn't mind the fact that he was forced to get another eyeful of his naked younger sister.
