"Hey Mike, are you ready to go?" Dustin said as he opened the door and came in. However, his neutral expression changed into disgust when he found out the three naked jocks in the room. "Ty? What did you do? And... ugh... what's that smell?"
"Smell?" Ty raised his left arm and sniffed his bushy armpits. "Nope, I smell the same."
"That's because you're accustomed to it." Dustin said. "Anyway, I don't care about your little gay orgy. I'm just looking for Mike. We're going to watch a movie."
"I'm here, Dustin!" The recently transformed dumb jock raised his right arm while he still masturbated with the other one. Dustin didn't say a word. That guy looked nothing like the boy he remembered, however he didn't doubt it was Mike because he knew what Ty's powers are capable of.
"Gross! Why did you turn him into that?" Dustin asked to his jock brother who was still sniffing his armpits.
"Oh, he wanted to be bigger like Jason and I granted his wish." Ty said. "Now, he's a dumb jock like his brother. Maybe a little bit more stupid than him."
"Well, changing back. The movie is going to begin in half an hour." Dustin said. "And please, reduce his libido. He has been jacking off since I came in."
"Sorry Dustin but I can't. My powers aren't working very well." Ty said as he patted his brother's back. He was too strong now that he almost pushed Dustin to the ground. "Let me show you."
"How?" Dustin asked but Ty didn't reply, he was concentrating in his powers. His stare was focused in Dustin's crotch. "Hey, what are you looking at?" Dustin tried to cover it from Ty's sight but it was useless. His power was already working on Dustin. "Wha-what are you doing to me?!! Aaah aaahh aaahhh~!!"
Dustin was pissing himself, or at least thst was Jason thought at first. But, in fact, Dustin was ejaculating so much and so fast that he quickly emptied his balls. His shorts were so soaked with cum that it was dripping through his left thigh. When he finished he fainted on the ground and didn't notice the next changes on his body. Fur began to sprout from his skin, his nail blackened and turned into claws while his feet became more bestial.
"What are you doing to him?" Jason asked Ty, while they watched Dustin's face getting a canine look. His ears turning long and pointy while they moved up his head and his nose blackened while he got a muzzle. "He's like a dog, a humanoid dog."
"My intention was turning him into a doberman but it seems he's only half dog, half human. I guess he can't go to the movies looking like that." Ty shook a hand and Dustin's clothes vanished in the air. Now, Jason can see Dustin's new sheath, his furry balls and a long dog tail swaying a little. "I will try to turning back!"
Ty focused ln Dustin's body again but instead of turning back to normal, his body started to swell like a balloon. His height shot up, his arms and legs lengthened and his muscles emerged from every corner. His abs, his pecs, his calves, shoulders, biceps and more. He was huge now!! Even his balls and sheath grew up to match his gargantuan body.
"He's monster!" Mike shouted when he finally noticed the creature in front of him. Of course, he was still jerking off. "Is a bad guy?"
"No, it's Dustin." Jason said. "Well, at least, he was. He's still in there, right?"
"Of course he is." Ty replied. "He's just sleeping. When he wakes up he'll be very horny. So, be careful." While Ty said that, a big red rocket began to emerge from Dustin's sheath. "Oh, it seems he'll wake up very soon!!"
