Ty watched as Dustin ran away. He willed the doors and windows locked, but let Dustin have his panic attack. Ty really didn't want to be the horrible brother, but it felt right. As bad as Mark and June were, Dustin was much worse. His foster parents didn't care about him, sure, but to Ty it seemed that no attention was preferable to a lot of attention in a bad way. Every day, Ty would wake up knowing that Dustin would be there, waiting to torture Ty some more. This included constant beatings and harassment, as well as embarrassing him in front of the few friends that Ty had. That Dustin seemed the only person aware of the changes only made things better. This was revenge in its most carnal form, condensed into a single period. And now that Dustin had insulted Ty, ignored him, and ran away in a matter of seconds, it put Ty on the warpath.
But what to do? Dustin was very proud, and most of that pride had been removed with his regression. but that left more for Ty to do. Right now, Dustin was cowering somewhere in the house, but Ty only had to blink and Dustin appeared in the corner of Ty's room, still attempting to hide. He screamed a bit, but the parents stayed asleep as a result of Ty's interference. Ty shrank back down to a normal size, a very big change, but he stayed about 20. The thirteen year old was left shocked at the rapid melting of muscle, and Ty just looked at Dustin and said, "You should have seen it when I did it to you." This caused Dustin to snap and try to attack, but Ty forced him back into the corner. Dustin watched as Ty mumbled to himself, occasionally twitching his nose, or blinking heavily, or even snapping. For about a minute, Ty continued on with what could be perceived as a set of spells, and Dustin felt no changes.
Finally, Ty stopped speaking, sweating a little, and sent Dustin back to bed. As his last command, he said loud enough to hear, "Sleep when you see all that I've done." This left Ty, alone, now 20 years old. Yes, it seemed reality could change around him and his wishes, but he was still subject to the loss of his own identity. There are no 20 year old foster children, so reality was already at its limits. In a few short seconds, Ty shrank back to 15 (and one day) and went into his bed. All the remaining muscled evaporated, and the rest of the progress that had been made disappeared as well. This IS what Ty would look like in five years, though, so that was a comfort. He quickly imagined up a man and a woman, who joined him in bed. By morning, Ty was content and happy, having sex all night, making a lack of need for sleep, and hearing the occasional cry from Dustin's room.
Ty made all of the evidence of sex from the night before disappear, and he cleaned himself up. The one major change he left, aside from everything with Dustin, was a now larger penis. Ty got dressed in clothes perfect for relaxing on a Sunday, but as soon as he walked out of the door, Ty saw that Dustin probably won't be thinking the same thing. Dustin was outside of the bathroom, showing off full frontal nudity to Ty.
This was going to be an interesting Sunday.
