Who knew, heheh, that gnolls got SO hungry?? Heheh!
I'm quite lucky that I got a, heheheh, filling snack when the Gnoll TF hit me this month!! hahah!
Thank you Mr.Vinter for your "donation" HAH! hahah! You were a great lunch!
May even compensate you for it! hehe
#Gnollvember #Gnollvember2025
Its Gnollvember, and I transform randomly whenever one of these special dates happens. So, while I was at the office, the Gnoll TF hit and I hulked out into a towering, ripped, heavyset gnoll with a huge belly. I'm very beefy, covered in coarse body hair that almost hide my patterned hide. My pecs are heavy, and they protrude and rest on my even larger belly, my large black nipples capped with heavy, ribbed gold rings. My Gnollish mohawk is a gnollish red, making me look a little out of place in an office environment, though you can tell im transformed given I'm still wearing a tie and I have a ripped, tattered work shirt still clinging to my form, for the most part. My belly is definitely the star of the show though, and its feeling very very empty now. Who knew that being a gnoll made you extra hungry? My employees know my proclivities, so Mr.Vinter was more than happy to be shoved up my puckered, dark, donut ass and straight to my guts. Its not only a great time for me, making my MASSIVE horse cock rip free of my pants and swell several feet across the floor, but also for him, my soft insides rubbing and squeezing him, making him moan through my belly, pushing his paws and muzzle against it. Its a great start to the day, I'd say!!

Kurtis Jr. @roidpuppy.bsky.social and I love trick or treat'ing and this year my Babyboy suggested we go as each other. Our custom ordered kigu costumes show off our best assets and we also wore Halloween themed jocks. Aren't we both just freakin' adorable?!

A massively muscular Giraffe wearing a kigu that looks like his son, Kurtis Jr., his huge pecs bulging out of the outfit and stretched out scary pumpkin face pattern jock straining to contain his huge cock and balls; his son, a hugely muscular and adorably cute Hyena, is wearing a kigu that looks like his Giraffe dad, his massive pecs are also bulging out of the outfit and his enormous bulge is covered by a happy pumpkin collage patterned jock. The are walking from one house to another during Halloween night, trick or treating. Kurtis Jr. looks to be bounding enthusiastically with an adorably dorky and excited look on his face as his huge Giraffe dad follows behind him, holding the very large sack containing their treats. KC has a happy contented look on his face as he views his Yeenboy

In the years it's been since we last heard of Judy and Nick, underground scientists have managed to synthetize a powerful serum from nighthowlers, one that increases muscle and testosterone instead of agression

After catching one of the serum smugglers, Nick may have... stolen some of the evidence
Nick Wilder looking absurdly musclebound. His body is thicker than doorframes, his arms wider than car tires. His balls are as big as beach balls and his cock bigger than a fire hydrant, stretching his underwear to dangerous limits. He holds a syringe of a purplish, glowing liquid. A serum extracted from nighthowlers and the source of his growth. He looks at the viewer with a smug smile. (Really musky version) Nick Wilder looking absurdly musclebound.
