Nothing like a good stretch to release the tension in those big, juicy, meaty thighs... 🤤

Stretching is even better "au naturale"! Full res + spicy alts of this piece are up on my Patreon! 🫶

After one hour of his first goon session, he started expanding rapidly, soon outgrowing his house. He surpassed his city by the second hour but couldn’t stop there. Now he’s up to hour eight and ready to extinguish the sun with his cock. He really should stop gooning… but it just feels… so… good!

“Hey Jake, have you… woah.”
“Bro, knock before you come in next time.”
“I will, sorry. It’s just… Fuck, dude. I didn’t realize you were so caked up.”
“Are you blind? My ass has always been this fat! Anyway, what were you going to ask?”
“…forget about that. Could I give it a squeeze?”

I accidentally put on a pup collar that I haven’t vetted. Now it’s causing extremely overwhelming, unstoppable ascension as my arms are pulled endlessly further away from taking it off!

How big will Pup Lightning get? 🐾⚡️

I gave an "hyper himbo" potion to @phantomsuperman1.bsky.social...

I warned Clark that the potion would turn his brain mass into muscle mass and that he would become a giant dumb hunk after drinking it, but he didn't seem to care.

He still seems smart enough to form sentences, so that's okay.
