"Give me those feet!" Jon exclaimed as quietly as he could so as not to disturb his sister. Imeediately he felt his own feet tingling, he looked down at them in the dim light of the room but couldn't make out any changes. When the sensation subsided he wiggled his toes to see if he could tell a difference, but he couldn't really. He then made out two shape on the floor nearby, a pair of his sister's black & blue 'skull motif' sneakers. "Now I'll find out" Jon thought, as he crept over and retrieved the shoes. He then slipped his feet into them...expecting them not to fit, but his feet 'slotted' into the sneakers perfectly.
There was a slight moment of worry when Zoe began to stir, Jon was aware that since he had used his middle finger on her, she would notice the swap if she woke up. Then what he say to her? But luckily she dropped back to sleep.
Creeping out of the room, Jon then looked down at his feet, they were clearly a lot smaller than they were a few moments ago, and his shuffled his feet, admiring the way his sister's sneakers looked on him.
"This is fantastic" Jon chuckled, as he disappeared back into his room, without reversing the swap or returning his sister's footwear. After closing the door, Jon sat down on the bed and paused...before slipping his feet out of his sister's shoes. "Wow!" he then muttered, as he gazed upon his toenails, which were painted a deep black. The toes themselves were distinctly feminine, and Jon just couldn't stop wiggling them while smiling. He knew they looked 'odd' attached to the ends of his own hairy legs, but he didn't really care about that.
After a few more minutes, Jon crept back into his sister's room to return her sneakers, and to swap their feet back. But a part of him wanted to keep experimenting with his sleeping sibling.
