Ty watched as Jason's cock changed into a monster dick.
Jason was so scared he looked in awe as it grew and grew giving Ty's throat time to recover.
Ty waited until it grew to full size. Having not given any specific animal that Jason's cock was to grow into it was the largest possible and reached from his crotch to way over his head.
It was truly massive.
Well now what are you going to do with that thing Ty giggled.
Change it back it is too big.
Ty said a few words under his breath and soon it was shrinking again. Inching down smaller and smaller. Soon it was the size that it was that Ty was trying to swallow but it didn't stop. It kept shrinking till it was the size of Ty's cock and still it shrank. What the hell are you doing to me Jason screamed. It went smaller and smaller.
Now the ultimate shrinking you would think would be the size a nub but it wasn't even that big. It pressed up against his body with a little pee hole for Jason to urinate from but not big enough for him to ever get excited from.
Please don't do this Jason pleaded with him.
The only way you are going to ever get off is if someone fucks you. And those grapefruit balls are going to keep you horny all the time.
Please I'm sorry.
Ty had him now. Pleading with him to turn him back. But now Ty had a slave, a sub, a boy.
And those fuckings can't be with someone average or small size they won't even reach your prostate to stimulate it. They have to be big dicks a foot long or better. Now someone could stuff their arm up there but that would really stretch you out.
Now one more little change.
Ty spoke a few more words and Jason began to dumb down like any jock should be. There to play football and be fucked. Those were all the things Jason knew now.
