Ty stood up from the bed and for the first time in a long time he felt genuinely excited. What a twist of fate, or birthday wish, or divine will, or whatever. It didn't seem dreadfully important *how* he got the power. Just that he now had it.
The image of Dustin shrinking down in front of his eyes was powerful. He had really done that, made his step brother a small fry with just a simple thought.
It was intoxicating.
Responsibility! His worried mind urged. Responsibility and restraint!
No, Ty decided, what could a little experimentation hurt anyway? If he screwed something up, he had a feeling he could just change it back anyway.
In the bathroom, Dustin's shower was winding down. The urge for some mischief was just too overwhelming.
With practiced stealth, Ty snuck out of his room and inched toward the bathroom door. He turned the knob slowly and stole into the bathroom without a peep.
The shower suddenly died, and the shower curtain flew open to reveal a soaking wet nude and suddenly horrified Dustin, barely more developed than Ty.
"Hi, bro!" Ty said cheerfully.
Dustin suddenly covered his small cock in embarrassment and took a cautious step back, waiting. "Please. Just turn me back!" Dustin asked politely. "I promise I'll stop kicking your ass and everything. Please, Ty. Just... change me back."
Now there was a moral dilemma. Grow his foster brother back into the big dumb jock he was, or do something else?
