Ty smiled when he saw the exposed and vulnerable ass on his lap. Jason was still red of shame and crying because of shitting in front of his little brother that he didn't look Ty's hands about to spank him.
"Aaahh!!" Jason screamed when his ass felt the strong hand hitting it. "Ty! Please let me go!"
Ty grinned, he thought that Jason's ass looked funny, small like a kid but hairy and muscular like a man. He didn't tell Jason but he wished to make it slowly bigger.
With each spanking, Jason's ass pumped a little bit more and more. The soreness was making it even bigger as the ass checks were turning red like tomatoes.
"Aaaah!! Aaaahh!!" Jason screamed each time Ty's hand made contact with him. "Please, Ty!! I'm turned on!!" He lied to get free but Ty knew that it wasn't true.
"Bad boy! Don't tell lies!" Ty shouted. "You need a punishment for that!" He increased his arms muscles, bulging his biceps to bowling ball proportions and making his hands way more biggee than before.
"AaaaaAAaaaAaaAAaAhhhHh!!!" Jason screamed when he felt the strongest spank until now. Ty's hand was now covering all his ass and even a little more.
"Now tell me you are going to be a good boy!" Ty ordered to Jason before he slapped his ass again.
"I'll be a good boy!! AaaAAahH!! I'll be a good boy!" Jason cried as he was spanked a few more times.
"Ok, that's enough for now!" Ty said as he put Jason off his lap. "Let's see if that was helpful." He saw Jason's dick but it didn't look different from before. "Hmm... Maybe we need more spanking."
"NO!!" Jason shouted. He tried to focus on get turned on but all he got was a loud and disgusting fart. "Shit!" Farting was way more painful with his swelled ass.
"Oh, it worked!" Ty grinned as he saw Jason's dick grew another inch. "Your dick has reached 3 inches now. Good for you, Jason!"
"Yeah, yeah..." Jason resigned. "I'm so proud of that..." He sarcastically said. "Now what..."
"Teehee!" Jason heard a giggling and quickly realized his little brother was still watching him.
"Mickey! Don't look!" He ordered but his little brother can't take him seriously with his small size and swollen ass. "Go out!"
"Sorry, brother." Mike said between giggles. "I cannot help laughing. You use to be an imposing jock and now you look like a circus freak!"
"Hey, Mickey." Ty said. "Don't you want to spank him a little?"
"Sure!" Mike said in Jason's astonishment. Mike looked so happy that he clapped a little. When his little brother was getting closer to him, Jason tried to run but instead of that, he magically floated to his Mike's lap, his tiny midget legs where on a side and the rest of him on the other.
"Come on, Mickey! Don't do this!" Jason pleaded. "I'm your big brother! Aaah!!" He surprisingly screamed when he felt the first slap on his reddened ass. "Aaah!!" He cried a few more times. Mike's spanking wasn't as hard as Ty's, but Jason's ass was way more sensitive than before that he felt pain just by the contact. "Aaah!! Aaaahh!!" Mike was smiling with satisfaction all the time.
"Hey, Jason. Why don't you give him a blowjob meanwhile?" Ty said with a wicked grin. "Don't you like that, Mickey?"
"Sure." Mike replied although he didn't know what it means. With his approval, Ty snapped his fingers and Mike's clothes vanished in the air, leaving him 11 year old body exposed. His dick was just 3 inches long, as big as Jason, but it was prepubescent and Jason was not. "Hey!" Mike shouted to Ty when he realized he was naked but he stopped complaining when Jason's mouth began to suck his dick against his will.
"Ohh!! That feels weird." Those were Mike's only words before he began a session of spanking and blowjobs with his midget brother for a while.
