sketch YCH C for @wookieluke on FA of her anthro goat monster OC, Butterscotch, stuck in a wall of murky fleshy tendrils that are using him seedbed by stuffing eggs down his throat and milking him relentlessly with thick, glossy suckers. He's so stuffed that he looks heavily pregnant, the eggs in his belly partially visible as they bulge against the skin. Also, where Butterscotch is embedded in the wall, the flesh has started to merge- tendrils reaching in thick veins over and under his skin.

digital YCH illustration of @nilysil's oc, Warren, squatting with his legs spread in a set of revealing deer themed lingerie that leaves his gravid pregnant belly, fat milky breasts, plugged asshole and gushing genitalia exposed. His face is meshed in pleasure as a womb tattoo glows on his belly,  and a torrent of squirt pools over an ejected sounding rod.

four stage growth sequence YCH illustration of @sirhc_x 's anthro cow oc, Bethany,  becoming increasingly pregnant after drinking a magic potion. 

1st stage: Bethany smiles and rubs her chubby belly with one hand and an empty potion bottle in the other.
2nd stage: Bethany says "milk... already?" as she squeezes milk from her swollen breasts. Her belly is visibly pregnant above her plump and leaking udder.
3rd stage: Bethany kneels and cradles her hugely pregnant belly, milk dripping from her almost head sized breasts and heavy udder as she says "well, that was fast~ wasn't it, "little" one?"- thinking the growth is concluded
4th stage: Bethany sits, back arched and mouth wide as a womb tattoo glows on her now hyper pregnant belly & her melon sized breasts and udder spray milk everywhere.

1. Eshe sucks Claire's cock under her nun's habit, Claire says "I have been visited by the holy spirit"
2 Claire cums into a goblet held between Eshe's breasts, she drinks from it with a curly straw. Claire says "May i prepare communion this week?"
3. Claire's POV as Eshe rides her, holding her hands as radiance gleams behind her. Claire says "Holy Eshe--"
4. Claire lays back, starstruck, saying "-fu-full of grace-"
5. Claire and Eshe lay atop eachother in a curtained booth, their backsides exposed and covered in cum as churchgoers queue to fuck them. Claire says "I am- ah-h-- called to serve"
6. In the booth, Claire kisses Eshe passionately while a gnoll fucks Claire's ass, a lizardfolk double penetrates Eshe's pussy with Claire, and a minotaur fucks Eshe's ass.

Her belly is so stuffed full of eggs that they can be seen glowing and bulging through her bloated belly that looks heavily pregnant.

A trans man wizard is gagged and tied with rope to a barred metal door in a stone dungeon. His shirt is undone, showing sigils on his chest and neck. His white tights are pulled down enough that we can see his pussy and the big cumshot making a huge mess. A tall bearded guard reaches through the bars to hold Cadogan's hips as he fucks him. Outside the cell, four other guards wait their turn. One holds the keys to the cell, one sits on a wooden box and jerks off, a twinky one hunches his shoulders and looks away scandalized, and one stands in line waiting his turn.

Cadogan's tiny familiar sleeps on the edge of a hay bed in the cell, a big snot bubble coming out of his nose, oblivious to the action.
