"Well Dust, after what i did to you yesterday by accident i wanted to see if i could do it again, so i made a wish on my self, and as ive always loved putting things in my butt, i wished that my butt was larger and could fit my football in it, the one in you now, and it worked, i put that ball in my butt and slept with it in me all night," Ty explained.
"Wow thats so cool," Dustin replied.
"It is! While i slept i wished that my ass could take more and that when it did my cock would grow every time my ass stretched, also that my ass would never hurt and always be ready to get stuffed and even make its own lube, so when i woke up it was a little wet and i wanted to see if it worked, and it did. Then you came in," he continued.
"So thats why i suddenly loved what you did?" Dustin realised.
"Yeah, i had to do something, didnt want you freaking out, so i wished that you loved it and wished that you could do it too, and that when you wished it your butt and cock would have the same abilities as mine." Ty told him.
"Cool," Dustin said just as they both started to feel the balls grow again.
They both rode the wave of expansion as they came again all over them selves, Ty was starting to get bored of the time it was taking and he was extremely horny and wanted to feel full so he made another wish without telling Dustin. 'I wish the balls expansion would gradually continue from now until they are the size of the largest ball, over a minute, our bodies wont show any sign of the expansion, they will both stay the same as they are now, but we will feel all of it in us, like our butts are larger on the inside,' he thought.
Suddenly they both felt the rather quick expansion, both in their butts and their cocks, they both panted and moaned as their cocks filled out and their butts filled up. After the minute was up they both felt impossibly full but looked just as thin as they always had, "did you make the balls grow Ty?" Dustin asked.
"sure did Dust, what did you think?" Ty asked.
Dusting excitedly replied, "I loved it! what else can you do? I want more!"
