Commission for TheNebraskanMan of their oc Aru getting stuffed by my Valeria! There’s only room for one lamia in this town… literally, at this rate. Enjoy!
Two pale lamias in Valeria’s weirdo stuffing dungeon. Aru is to the right, being crammed full of delicious sweets from Valeria’s magic. Valeria is leaning against her with her own plump body, taunting as she works. “There can only be one lamia around here! The least I can do is send you off on a full stomach~.”

A friend hit me with some brainrot a little while back so now Reese’s a giant waterblimp and Shannan’s taking full advantage. Enjoy!
My ocs Shannan and Reese, Reese is tipped forward and swollen to the limit with water. A giant hose is gushing into his ass while drops of water spew from just about every opening he has, despite his taped shut mouth. His partner Shannan is happily humping his overfilled tits, flirting with him too. “Nnnnh… Gods, babe… you really are my favorite fuckable waterbed~”

Double post! Shannan and Reese with some big ass bulges. Simple as. Enjoy!
Shannan and Reese at the beach, both only wearing tight speedos containing their gigantic bulges. The two are smushing them together, with Reese barely able to contain himself. “Mmn… Feels great to let loose doesn’t it babe?”

Y’know my art’s been doing worse across every site i post on recently, makes me wonder if its my terrible algorithm habits or if something’s actually wrong with my art
I’m still on a legendary productivity streak when it comes to drawing so thats good at least

Commission for @cyclonensfw.bsky.social of my oc Agatha! They’re on the mend from a leg injury but I don’t think that’s impeding their movement at this point… Enjoy!
My puffin harpy oc Agatha, extremely fat to where they can barely move, surrounded by empty fast food bags and remains. They’re nervous about return to work due to gaining an insane amount of weight during recovery. “Yeah, my leg’s almost *hff* fully recovered, boss!” “R-Return *hff* to work!? Ah… There could *pff* be s-some… complications there…”

Another set of sketches! Fatass!!!
Mason in his HyperTech jumpsuit, in the middle of testing a new heavy duty railing meant to support hypers. He broke through it, and is now flailing wildly on the ground and overreacting. “AGGHHH HEEELP HELP I FELL OH GOD I THINK I BROKE A RIB HEEEEEELP” “Rail test 3 is… a failure.” “Shouldn’t we help him!?” “Check the scanners, he’s perfectly unharmed…” “Oh.” Mason at his usual size and humidity, waddling out of the store carrying bags and bags of freshly bought TCG product. His pants and boxers are undergoing a legendary level of wardrobe malfunction… “Hey fatass! Your pants are slipping!” “Oh shut UP. Your winrate is slipping!”

(CW: bulge)
First four sketches, featuring Fiora, @guy5716.bsky.social’s Jasmine, and @tempesttim.bsky.social’s Miriam!
Mason and Fiora, both visibly swelling with angry, mashing against each others’ sweaty bodies while passionately debating shitty hentai manga preferences. “UGH for the last time, Super Yaoi In Space is WAY better than your stupid… WHATEVER you read!” “CAN IT, COW! Medieval Lesbian Knights XXL is a MILLION times better than your lame early 2000s sci-fi SLOP!” “Yeah yeah just keep repeating it you dumb landwhale! Get your sweaty fatass outta my face and go read something CLASSY for once!” “Et tu, brute!” Mason with his older sister, Jasmine, out while discussing Mason’s fitness. Mason is visibly sweaty and nervous at the mere thought of exercise while Jasmine is pouty that he won’t take her offers. “I’m just sayin’ lil bro you’re always welc- oh my GOD are your seriously sweating from just HEARING about exercise!?” TempestTim’s Greedent girl Miriam in a heated TCG battle with Mason at a tournament. They’re both using the same annoying deck and taking long times on their turns… “UGHHH How many combos are you gonna DO? LEMME PLAY MY TURN!” “Oh WAH WAH It’s a COUNTERspell for a reason! Go back to Pokémon if you want a baby TCG so bad…” “Better than your stupid 20 minute combos…” An absurdly massive Mason, sweaty and swollen his own hot air. His massive bulge stretches his boxers to their limits, his hands and feet the size of basketballs. He probably got challenged to hold in his lame opinions for 20 minutes.

Introducing a brand-new oc, Mason! A massive nerd with an overzealous attitude and overstuffed waistline. Some extra sketches of him will be in the comments later today too. Enjoy!

Commission for @witchfrommercury.bsky.social of their oc Elulara and their friend’s oc Morag! No witty caption for this one, just a pair of fatasses! Enjoy!
An extremely fat kelpie lady, Morag, slapping her friend (or gf? Idk actually) Elulara’s ass as it suddenly swells up, shredding her usual cloak. The catgirl’s pretty flustered about this
