Hi Size community, let this be another reminder to anyone not in the know,

FUCK ICE

FUCK CHRISTI NOEM

And fuck you if you support them. I hope all of your heads end up on spikes for the atrocities that are committed by this corrupt regime day after day.

"Pathetic, can you even call those muscle?" The giant flexed his rock-crushing biceps as the tiny tried to show off his weak in comparison physique. A deep laugh rumbled through the valley as the titan leaned closer. “You can't compete, don't even try.”

I might as well use this post to explain where I've been. Answer: Nowhere really. I just got kinda bored of drawing hyper muscle art. I still got commissions open if anyone wants hyper muscle art made by me.

Enjoy the Milo art as a gift from me.

All the cute twunks can't seem to help themselves and cop a feel. Can't Say I blame them though. Featuring @colossalmuscle.bsky.social copping a feel of my awesomeness.

My OC Is incredibly gigantic and packed with hyper muscles, cock, and balls. The lifegaurd uniform is stretched wonderfully across his massive body. A 7ft tall, extremely muscled and bulge, beach goer just comes up to the big guys hip. The beach goer isn't even half the size of the big guys single leg.

Hayden turn in bed and felt something warm pushing against his legs. Startled, he pulled the covers off in a sleepy daze and found something truly terrifying. His penis had grown into a massive, hulking horse cock over night! When he went to sleep he was barely 4 inches hard, but now this veiny, two-foot beast was drooling along his sheets. The torn remains of his briefs pushed to the side. Hayden panicked. Why was this happening to him? What was he going to do with a dick this gargantuan?! And then it slipped further along the sheets... the sensitive tip making Hayden shiver as it dragged further away... It was still GROWING!! Throbbing bigger and BIGGER!! What was this poor boy going to do?

The box art read ‘if you grow in the game, you grow in real life.’ He chalked it up as a stupid marketing ploy, but once he saw his heavy bulge after beating the tutorial boss, he knew he’d be raking up hundreds of hours in this game… and hopefully grow hundreds of pounds as a result!
