Ty grinned wickedly, as he changed Dustin subtly.
Dustin suddenly discovered that he wasn't as inanimate as he thought. He could move his fabric body,if he concentrated. Ty felt a wedgie forming between his butt cheeks. He laughed, and made another change. Damn, thought Dustin, I'm starving. What do morph suits eat anyway? Then he knew. Damn, Ty, if he wasn't so hungry. Ty felt the fabric around his crotch tighten and begin to move rhythmically.
Ty lay back and let Dustin do all the work. If he hadn't tuned out Dustin's mind, he might not have enjoyed it so much, as Dustin was pretending that he was milking a cow, and that Ty was a cow with one udder. He thought maybe he could trick Ty into growing more cocks. He wondered if there was a way he could somehow steal or at least borrow Ty's magic. As Ty exploded into the morphsuit, and Dustin absorbed all the delicious "milk", Dustin felt Ty's mind relax. He was linked to Ty, and as Ty dozed off, Dustin suddenly found that he could look into Ty's sleeping mind.
Now most people might have thought about Ty changing them human again, but Dustin was sure it was only because he was a living morphsuit fed on Ty's cum being worn by Ty that he was able to penetrate into Ty's subconscious. So he concentrated on making Ty never want to take Dustin off, and even suggested to the sleeping Ty that he should make everyone think it normal that Ty walked around in his Dustin morphsuit 24/7. He hinted that Ty's power was stronger when Ty wore Dustin.
Ty woke up about 20 minutes later. He felt great. He felt more powerful. He really felt good wearing Dustin. He should have changed Dustin into his morphsuit first thing when got his powers. He wished he could do it all over again. Ty blinked. He was back in his bedroom, and June was shouting at him that he would be late for school. He wasn't wearing Dustin, yet. He grinned and walked through the wall into the bathroom where Dustin was showering. He grabbed Dustin's shoulder, and his still big foster brother instantly became a red spandex morphsuit. Ty laughed, as his clothing vanished and his pulled on the Spandex suit.
Dustin was freaking out. How did Ty do this to him? What was the twerp up to?
Ty frowned, and then he realized that this version of Dustin didn't have the memories of the Dustin he had worn earlier. He tried to snap his fingers, but the fabric silenced the snap. But it didn't really matter, Dustin suddenly had the memories of being turned into a wimp, and eventually a morphsuit and then influencing Ty. Dustin immediately started massaging Ty's crotch. Ty moaned. He walked back through the wall and lay down. June shouted again. Ty waved his hand, and June started barking. After blowing his third load, Dustin suggested Ty might have more fun if he had two or three more cocks and balls. Ty didn't realize it but as he blew a half dozen more load, and zoned out, Dustin started making more suggestions. The pleasure center of Ty's brain grew larger and his the grey matter shrank. His mind was now outsourcing much of the thought process to Dustin. Everyone would assume it was normal for Ty to wear Dustin the morphsuit 24/7, it was normal. Dustin got Ty to stand up in front of the mirror. Ty's eyes were closed, but Dustin could see for both of them. He slowly coaxed Ty into reshaping his body into a bigger more muscular twin of Dustin. Then when Ty tried to exert some control, Dustin forced idyllic pastoral images into Ty's mind, and massaged his four cocks vigorously. All four cocks exploded at once. Now Ty in his spandex morphsuit was no longer in his room, but instead was on all fours in field. Dustin knew his shape changed too to match Ty's new shape.
