ooops this ended up being a small sketchpage, she's fun to draw ❤️ #art #furryart #nsfw #fatfur #weightgainkink
Sketched black-and-white sequential illustration of Cupid, an anthropomorphic ferret fursona of @cupidize.hyper.wang, gaining weight. In the first image she looks more full-figured, with her bra and panties stretching out from her girth. She is munching on a chocolate chip cookie. The second image shows her after having gained a lot of weight, to which many would consider this size 'SSBBW.' She is unclothed in this image. More notably, her fat distribution is even in a lot of places except her bosoms which store a disproportionate amount of fat; they are huge compared to the rest of her body (belly included). She is enjoying an ice pop.

Illustrated black-and-white sketch of Sertimus about eight times as fat to the point of being a blobby landmark. Their emote ball also swelled to about four times its normal size.

Raunchy doodle page...

#art #furryart #nsfw
Black-and-white doodled illustration page of Sertimus' anthro form naked and in a naughty mood. Top left drawing is of him on his knees, tasting pre-ejaculate from a hyper cock underneath a skirt. Bottom-right drawing is of Sertimus in the same posture but with arms out and resting on the floor. He is in a rather flirtatious mood.

Surprise! I am @leezord-vibez.bsky.social's Secret Santa for this year's event by @edgebirb.bsky.social. :> I struggled a bit with scale for this piece but hopefully it is enjoyable either way! Have a Happy Holidays!

#art #furryart #suggestive
Flat-colored illustration of Dullahan, a forest spirit, in glee after seeing the sugar cookies left behind for him on a tray. Adjacent to him is a Christmas tree, a window with a dark sky and snow in view and a dresser drawer, all in a dimly lit living room. The text above the scenery reads "Happy Holidays!" with the first word in red and white stripes, and the second word in green and white stripes.

Something looks a little different about them though, as if they turned into a 'sumo' chao and packed on some more pounds..
