“… go ahead and fuck Brimstone,” the voice abruptly commanded.
‘You can’t!’ Jason shouted from inside Brimstone's mind. ‘You can’t make us do that! That’s my sister!’
“Awww, poor bitch,” the sinister transformation demon whispered directly to Jason, “still in denial I see. Well don’t worry, maybe being bred by a big strong male will help you appreciate the wonderful blessings that you and your sister have received. Now then, Brimstone,” the voice commanded, “go and present yourself to Anvil. You will let him breed you until he is satisfied. Is that understood?”
Despite Jason’s internal screams of horror, Brimstone gave a swift nod of understanding. She then positioned herself in front of the massive pig-demon, before seductively lifting her tail and flashing her dripping black cunt to her soon-to-be mate.
In response, Anvil locked-on to the quivering spade between Brimstone’s legs, as his massive corkscrew cock immediately stiffened in response. The giant boar creature then surged forwards, before greedily burying his snout between the hellhound’s legs. He then delivered a firm lick to her hot, slick vagina, which caused Brimstone to whimper as her whole body tingled in lustful anticipation.
“Oh yes, what a good boy!” the voice said encouragingly, as Anvil greedily lapped at Brimstone’s pussy with fast, slurping licks. The pig-demon quickly became intoxicated by his partner’s pheromone-laced juices, as they splattered messily over his snout and the floor below.
Predictably, not everyone was enjoying this performance, as Jason and Alice desperately tried to resist from deep inside their fleshy, demonic prisons. Both were constantly struggling to regain even a small measure of control, but the entity’s dark magic and superior willpower prevented them from doing so. Instead, Alice got to feel Anvil’s massive throbbing cock as it began dribbling with salty pre-cum, while Jason could sense Brimstone’s nipples hardening and her pussy fluttering in anticipation.
Sadly, Jason’s and Alice’s continued defiance did nothing to halt their bodies’ arousal and excitement. After a short while longer, Brimstone signalled that she was ready to take things to the next level, as she stepped away from Anvil and looked back at him suggestively. She then let-out a needy whine as she lowered her front-half, lifted her tail and wiggled her ass excitedly, as she offered herself to the massive male eyeing-her-up eagerly.
As expected, Anvil could hardly resist such an invitation. He therefore wasted no time in mounting Brimstone’s muscular ass, as he gripped her tightly with his forelegs and started hauling his way up and over her spine-covered back.
The sheer weight and mass of the enormous pig-creature was difficult to handle at first, but Brimstone was quickly able to adapt as her own powerful physique helped her stabilise herself. Then, once her lover was in position, the eager young hellhound was delighted to feel something long, wet and hard brushing against her thigh. This prompted her to look down beneath herself, past her rows of softly-jiggling teats, to the enormous corkscrew-shaped cock now hunting eagerly for her needy bitch sex. Being beneath such a dominant, well-endowed male made her horniness grow even wilder. She couldn’t wait to be fucked by this handsome stud and receive his massive, creamy load. This was what she was made for…
“AWWWOOOOO!!!” Brimstone cried, as Anvil unceremoniously shoved six inches of his massive demonic cock into her tight, wet cunt. The hellboar then continued his advance, as he forced another two-thirds of his impressive length into the receptive female beneath him. This left the demonic bitch trembling and dripping in shameless bestial desire, as her inner vaginal muscles started to milk and squeeze around the thick, girthy shaft buried deep within her loins.
As arousing as this position already was, things soon got even more intense once Anvil’s thrusting began. Brimstone growled her approval as the massive porcine cock started to pump forcefully in and out of her sopping wet channel. This rhythmic motion stretched, filled and rubbed her pussy in just the right way, which caused electric jolts of pleasure to shoot all the way up her spine, as she shuddered and arched her back in pure, unbridled ecstasy..
Very quickly, the two lovers settled into a steady mating tempo, as the passion and urgency of their movements continued to steadily build. Brimstone started to yip and bark excitedly as her eight teats bounced pendulously beneath her. She also loved the hot, wet squelching sounds coming from deep inside her stuffed vagina, as various sexual juices were compressed within the confined space and forced out around the rapidly-pumping demonic cock.
Things continued like this for a short while longer, with Anvil and Brimstone furiously fucking, whilst remaining completely oblivious to the faint voices inside each of their heads, begging them to stop. As a result of this, both creatures started to build towards a powerful demonic orgasm, as their mating reached a fever pitch. Then, the floodgates finally burst not long after, as the passion-filled couple climaxed at around the same time…
Brimstone howled in joy and Anvil grunted in release, as the first powerful blast of demonic cum erupted deep inside the hellhound’s fertile womb. A dozen more jets of gloopy black jizz then swiftly followed the first, as Anvil started to empty his painfully-swollen testicles into the receptive young female beneath him. As a result, Brimstone’s already-stuffed vagina was soon left overflowing with excess seed, as she utterly failed to contain the sheer virility of the impressive male specimen on her back.
Anvil continued ejaculating for an unnaturally long time, as he unleashed what felt like gallons of creamy boar semen into his mate’s quivering loins. A disgusting puddle had even formed on the carpet below, while strands of wetness clung messily to Brimstone’s hind legs and ass. This left both demon-creatures swimming in an amazing post-coital afterglow, even if their tattered human personalities were utterly revolted and ashamed by what they had just experienced.
Eventually, Anvil’s balls started to run dry, as the last watery discharge splattered wetly into Brimstone’s cum-coated vaginal passage. Then, after resting for a few moments, the pig-beast finally dismounted his mate with a heavy thud. This caused a fresh spill of excess semen to flow out of Brimstone’s well-bred passage, as her pussy lips remained parted for a few moments before finally sealing themselves back shut.
With that, the action gradually died-down, as Anvil moved away to catch his breath. Meanwhile, Brimstone was left panting and still-dripping with copious amounts of cum, as she awaited fresh orders from her sadistic master.
“There we are dear,” the voice whispered in Brimstone’s ear, though it was clearly speaking directly to Jason’s lingering human mind. “I bet it feels good to no longer be a virgin!”.
‘N-no…’ Jason weakly thought, as another thick dollop of cum spilled messily from Brimstone’s pussy and stained the carpet below. ‘You’ll never make me enjoy this!’
“Oh, we’ll see about that,” the voice replied slyly. “Now then, I think you ought to tidy-up before round two…”
With that, the voice gave Brimstone a meticulous set of instructions. First, she was ordered to lap-up the disgusting puddle that had formed on the carpet. As it happened though, she rather enjoyed the taste of Anvil’s salty demon seed, meaning she quickly gulped it all down in barely any time at all.
Next, she was told to tidy herself up. This involved collecting the various fluids streaked across her ass, hind legs and inner thighs, which again she rather enjoyed the taste of. She then had to focus on her vagina itself, which she lovingly cleaned with her broad, slobbery tongue. These hot, slurping licks also caused more excess semen to slowly ooze out of her trembling spade-shaped folds. This meant that she had to actively bury her tongue inside herself in order to stop the constant stream of wetness rising up from her depths.
Once her cunt was completely spotless, Brimstone was finally ordered to service Anvil’s loins, now that he had fully recovered from their first passionate encounter together. To that end, she enthusiastically licked Anvil’s leathery sheath, in order to coax his demonic member back into view. She then greedily started sucking and slurping over his veiny, corkscrew-shaped shaft, collecting any lingering strands of dried cum and feminine arousal as she went.
After all of that, Brimstone was given absolutely no reprieve, as the voice once-again ordered her to present her pussy, which she dutifully did. And so, Anvil ended-up taking the horny demon-bitch a second, third and fourth time; each of which ended with him feeling immensely satisfied, while his partner was left overflowing with viscous black cum.
Mercifully, the voice eventually seemed satisfied, once Jason and Alice had been utterly defeated and subdued within their twisted demon bodies. They were still fully aware and conscious, but their sparks of resistance were much dimmer than before. Both were still filled with anger, fear, disgust, regret and a thousand other emotions, but they now firmly understood who was in charge… and it wasn’t them.
With its point made, the evil entity gave fresh instructions to its two pets, as it sensed that there was another lost soul nearby, who was in desperate need of rescuing.
And so, Anvil and Brimstone left Alice’s bedroom, before heading towards…
