commission for anonymous of t4t ceroba/starlo w/ some tasty impreg~ this was super fun to work on!

[ #meekzart #meekzission #undertail #undertailyellow ]
ceroba ketsukane, fully undressed, balls deep inside of starlo, who is still partially dressed, a large amount of semen dripping out of his pussy. ceroba smiles contently and says, "Ready to bear my pups, Starlo? ♥" and starlo, overstimulated and drooling, replies "A-Ah-- Yes... Ngh..." there's an x-ray bubble showing a cartoonized fertilization within starlo's womb. the same but without the fertilization x-ray

I need this fucking boyfailure and his fluffy chest NOWWWW

#undertailyellow #undertaleyellownsfw
Chujin, either naked or just topless, with his arms behind his back and his chest (extra fluffy) out in show as he looks confident with nervous sweat on his head. He's nervously but confidently saying: "Breedable? HA! I am far f-from that! Y-You're just acting tough around me aren't you?"

clover receiving head for the first time in their life at the hands of a hungry beast (chara)

[ #meekzart #undertail #undertailyellow #cocoapowder ]
as the post says. clover is moaning out loudly in pleasure. chara’s not wearing their top sweater/shirt so it’s harder to tell that they’re chara, but they are, i prommy.

IT'S FINALLY DONE I CAN POST IT YIPPEE YIPPEE YIPPEE HAPPY BIRTHDAY TO MY BEAUTIFUL GF #undertailyellow
Martlet holds a cinnamon cookie in her wing, with her other wing around a fat, queasy-looking Ceroba. Martlet wears a blue shirt with blue pants, while Ceroba wears a white set of underwear and red thigh highs, with noticeable rips in the top and stockings. In order, the dialogue goes like this: Ceroba: N...no more...please... Martlet: Awww, come on. Not even a cinnamon cookie? Ceroba: I'm about to fucking explode... Martlet: I think you can handle a little bit more than that...Just one more cookie, okay? Ceroba: Ugh... Similar to the previous picture, but both are now completely nude. Similar to the previous two, but only Ceroba wears clothes. Similar to the previous three, though only Martlet wears clothes.

Ceroba Ketsukane , a yellow Japanese inspired fox monster, is squatting down as she talks to a much smaller anthro deer/fox character who is excited by the encounter . Her teeth are very pronounced, her expression is flirtatious.

Seems like Ceroba is a little hungry though~
Ceroba Ketsukane , a yellow Japanese inspired fox monster, is squatting down as she talks to a much smaller anthro deer/fox character who is excited by the encounter . Her teeth are very pronounced, her expression is flirtatious. Her dialogue has been changed to imply that she’ll eat the smaller character.
