digital illustration of @respectablecit1 's demoness, Tonya, having sex with three werewolves as she lays spread eagle on a table in a nightclub wearing nothing but a rolled up miniskirt. She smiles coyly with an empty margherita glass in hand to collect tips from her eager patrons. Her thighs are covered in lewd bodywriting and tally marks, and her cock is erect and leaking. One werewolf is resting his cock against her snout while she wraps her tongue around it; the second rests his cock under her breasts; and the third has buried his cock half way to the knot up her ass. digital illustration of @respectablecit1 's demoness, Tonya, having sex with three werewolves as she lays spread eagle on a table in a nightclub wearing nothing but a rolled up miniskirt. Her margarita glass is overflowing with cash from her satisfied patrons. Her thighs are covered in lewd bodywriting and tally marks, and cum shoots out of her rock hard cock. One werewolf has sunk his cock down her throat, cum bubbling out of Tonya's stretched lips as she takes him up to the knot; the second rests his cock under her breasts, leaking cum all over her; and the third has knotted her cum-slick ass, stretching it wide as his full length is buried deep inside her.

#nsfwart #commission #furry #slycooper
sketchpage comm of threalncp's medieval knight sly cooper oc, Sir Edward Johnson, pining after Sir Galleth Cooper. They spar at first, until Edward gets so flustered after pinning Galleth down that he has to excuse himself before the other spots his growing erection. Edward tries to relieve himself in private while fantasising about Galleth and recalling a drunken night of lovemaking between them that he doubts the other remembers. He cums, but his erection doesn't go away. The next day, the two patrol the forest and stop for a moment so Galleth can fix his laces. In conversation, Edward comments on "taking in the scenery" and Galleth teasingly implies Edward is checking him out. This flusters Edward & while Galleth tries to assure him he was only teasing, both of them are visibly hard. Galleth's thoughts reveal he reciprocates the attraction, and commends Edward's self restraint.

Sly blushes deeply and bites his lip, cum leaking from the tip of his cock. Dialogue between them reads- Sly: Ah- Neyla- I can't believe I'm letting you d-do this to me b-but- f-fuck -- your tongue feels so good in my a- ah- ass! Neyla: oh, I can tell, Sly~ You're leaking all over yourself like a dirty, sissy sly & you love it, don't you? Sly: mm-yes! I- I think i'm gonna- Neyla: -cum again? I guess I can eat your cute little ass a little bit longer, then~ & when i'm done, that tight, needy hole should be ready for some fingering Sly: fu-uck - neyla, I- I--

#commission #nsfwart #furry #tf #expansion #slime
sketchpage of ken_beanAD's anthro sabertooth-cat woman, Ken, in various erotic poses & situations in a lab. Nude aside from a white labcoat, in one drawing she poses with it open to show off her body, and in another sketch is bent over her desk with the coat so soaked through it's made see-through. In another, she drinks something from a test-tube that makes her fat & voluptuous. In another, a beaker breaks and splatters green goo all over her, which slowly transforms her into a horny slime-girl.

Layne is a trans man with a body composed of blue slime. He has purple horns, dark blue hair, yellow eyes, long furry elven ears & tail ended with a tuft of fur . He is glancing nervously down as the tentacle pushes through his ass, bulges his belly and pokes out his mouth- pink slime oozing from both ends and glowing inside him. Alt of the YCH illustration of gumgumtum's slime dragon, Layne, being fucked all the way through his ass and out his mouth by tentacles and heavily slime-inflated by them whilst restrained. Layne is a trans man with a body composed of blue slime. He has purple horns, dark blue hair, yellow eyes, long furry elven ears & tail ended with a tuft of fur . His eyes are rolled back in bliss and tearing up as his belly, swollen to the size of a beach ball by pink gooey slime, bulges out and squishes against the tentacles in front of him. He is stretched so much that his blue skin is near transparent, allowing a clear view of the goop inside him.

Avin is a muscular male snow leopard with grey fur, a pale underbelly and dark grey spots and stripes. He is wearing a yellow collar on his neck, which a tentacle has wriggled under. Avin's yellow eyes are rolled back in overstimulated bliss as the tentacle reaching out his mouth spills glowing pink ooze down his chin. Similar goo is slicked all around his ass and the base of his tail & drips down to his sac as the tentacle stretches him wide.

Coincidence and Greyfell tried their best to escape their rather... intimate predicament, but several devious enchantments meant that there was no "breaking out" until those fertility seals were well and truly "broken in".

A fertility seal over Coincidence's womb glows brightly. middle: Greyfell moans and Coincidence gasps as the bindings pull them down- slamming them over his knots and almost forcing them in. top right: internal view of Coincidence's cunt stuffed full of Greyfell's cocks- his tips kissing their cervix while knots keep them locked in. bottom left: Coincidence rides Greyfell roughly, cum splattering between them in thick ropes as a fertility seal on Greyfell's enlarged balls glows brightly. bottom right: Coincidence arches their back as milk sprays from their tits & their belly swells to a sudden, gravid pregnancy- bred by greyfell & sped along by the seals.

Arel is a transmasc purple skinned drow elf with mid length white hair, purple eyes and white freckles on his cheeks. He is wearing a black cropped sweater that has rolled up, exposing his breasts, and a black mini skirt is flipped up to show his ravaged hole and slime slick cunt. A long thick tentacle plunges into his ass, reaching all the way through his bulging belly and out his throat; black slime spilling out of Arel's stretched lips and bubbling out his nostrils as he gags on it with tears rolling down his cheeks.

comm for @/cleverADname on twitter their oc Blade finding himself in something of a sticky situation with an amorous latex ooze 🖤💦

--
#nsfwart #commission #tf #latex #slime #furry
a digital illustrated sequence of cleverADname's oc, Blade, getting caught by a black latex slime monster that fucks him and transforms him into a bimbo drone. Blade is a thin, athletically built male anthro fox with white fur, pale grey markings and long white hair streaked with red and worn in a braid. First, Blade looks over his shoulder nervously as the slime restrains him and raises a large, phallic tendril to his exposed, glistening asshole. His hard cock leaks in excitement. Second, the slime spitroasts Blade with two thick tendrils and oozes over him, half encasing him in shiny goop. Plump breasts form where he once had a flat chest, and his cock grows and leaks black goo. Third, Blade is fully encased and transformed into a near featureless bimbo drone by the slime. He now has a curvaceous hourglass figure, with both his lips and asshole plumped for easy fucking. He sits with his legs wide and enormous cock rock hard and cumming latex goop everywhere.
