A Rutting Pair

Rita opened the door on quite the scene. Abbey was currently plowing her new girlfriend from behind with a massive, monstrous cock that protruded from her crotch. Below the cock bounced a pair of fat balls, each one glowing a malignant violet color.

Apparently, Abbey’s new testicles had gotten some practice as night-black jizz leaked from Sadie’s stretched pussy onto the cold tile floor.

Rita noticed with glee that the massive amount of demonic cum pumped into Sadie had not left the girl unchanged. Black veins marbled the girl’s pale skin. Even more thrilling, the formerly petite girl was beginning to fill out massively, her nascent rack stretching her formerly loose blouse to the breaking point.

Rita couldn’t help herself. She just had to join in with the fun. She felt from deep within the lovely writhing pleasure as her own worm cock emerged from between her legs.

She stripped out of her pants and stepped over to Sadie, her massive appendage bobbing and swinging.

Sadie looked up at Rita, tears streaming from her eyes. While she had always been a pretty girl, Sadie now was a perfectly carved specimen of lust, whether she liked it or not.

Rita took the opportunity to shove her worm cock into the dazed girl’s mouth, burying her piece up to the hilt. The sensation of the girl’s soft pillowy lips and warm tongue was out of this world.

Then Rita began to pump, slow at first, but soon more quickly as she lost control of her desires. Sadie let our moan after muffled moan, the sensation of being impales two-ways proving too much for her.

Soon, Rita felt the ungodly, magnificent rushing pleasure as her own tainted seed poured into the girl. She burried herself deep in Sadie, making sure the girl took in every single drop.

Of course, Rita wasn’t done. After all, she was a demon. She immediately began to thrust again, not even attempting any buildup this time.

From the other side, Rita heard a low, growling moan and watched Abbey tense up and she blasted another load into her lover’s wet snatch.

Blast after blast of corrupting seed poured into Sadie, filling her with more darkness and corruption. Soon, the girl’s breasts, A-cups before this point, became so large and heavy that her tight shirt could not contain them. It ripped along the neckline, freeing the transforming girl’s massive right boob.

Rita reaches under a tore off the remaining fabric before fondling the girl’s massive, demonically enhanced rack.

Sadie’s hair darkened to pitch black and grew longer and unkempt. Her soft brown eyes closed and reopened burning like a pair of hot coals.

Her fingernails lengthened and sharpened into stylish black claws and her canines became a pair of dazzling fangs.

Sadie’s full lips turned black, as did her swollen nipples. From her bountiful tits, black milk began to dribble.

All the while, Rita and Abbey continued to pump load after transformative load into Sadie. It was as if the girls were competing to see who could empty the most spunk into their lovely little prize.

Monstrous horns began to erupt from Sadie’s forehead and spade tale with a sharp barb at the end of it slinked from above the girl’s full ass, marking her full transformation into a demon.

Rita and Abbey, sensing Sadie crossing this threshold, both suddenly hit simultaneous orgasms. Rita yanked out and began to plaster Sadie’s face and tits in her darkness.

Meanwhile, Abbey lodged her cock deep, hoping to fill her new girlfriend with as much of her essence as possible.

Sadie stretched her arms, her perfect titties bouncing as she did so. The girl looked out on the world with the fresh eyes of a child, her very existence reborn in darkness.
