Jim admired the pale horror pumping the black seed from his cock with her massive tongue. Cathy made a sickly gurgling sound as she savored each slimy drop.
Bobbi whimpered in sexual frustration as she watched her master get serviced by his newest minion. She let loose a frustrated growl as she nearly pulled the door off its hinges. Even with her enhanced sense of smell, she could only barely make out her mother's scent over the musky odors in the bedroom. The werewolf lowered herself into a feral crouch, snarled and charged down the hall out of view.
Jim savored Cathy's ministrations as she drank ravenously from his cock. His eyes rolled back in his head as he came thunderously into her tongue and enormous fanged maw. The climax only made him hornier as his cock was not exhausted by one mere orgasm. Cathy detached her tongue, Jim's black seed dripping from between her massive fangs. The pale demoness hissed wantonly as she leaned back, claws scraping the floorboards. She spread her white legs, baring her engorged blue snatch to her master. Jim entered her unceremoniously, fucking his slave like a wild animal. Cathy let out a high-pitched shriek, tongue flailing wildly as Jim pumped gallon after gallon of corruption into her.
He was roused from his revelry by the sound of a human scream. “Mom,” he said as he slowly opened his eyes.
Bobbi had thrown her mother down on the floor next to Cathy. The older woman's clothes hung in ribbons from her limbs, her skin scratched by the werewolf's claws. Jim, like most children, had long been dismissive of his mother's beauty, unable and unwilling to think of her in sexual terms. But things were... different now.
“What are you? Where are my children?” she said defiantly, green eyes flashing.
“Don't you recognize us? I guess we've changed a bit,” he panted as he withdrew from Cathy.
“That's... that's not...” the defiance became revulsion and terror. Jim's sisters laughed monstrously.
“Possible?” Jim offered. “Heh. I can understand if you're not entirely happy with how we turned out. You tried so hard to instill us with decent values. But fear not, you can always try again with your next batch.”
Jim savored the look of horrified confusion on his mothers face for a moment before his eyes crackled with demonic energy. Green lightning leaped from his pupils, striking his mother right between the legs. Mom gasped in surprise as her loins erupted with a jolt of pleasure. She looked down, confused by the copious wetness soaked her panties. She lowered her finger toward her groin, pulling it away reflexively as she noticed something writhing underneath her panties.
