The day has only just begun~

(I've been trying to get this out for the last MONTH now. Every chance I have to work on it though is interrupted by something. Regardless here is what I'd HOPED to have long before Halloween had come and passed by.)

I hear those words echo through my head, then I hear a growling coming from the portal. I can just manage to turn my head, it's enough to see 3 figures come walking out, each about 7ft tall with athletic builds, their cocks are only around 3ft long each... As the light helps reveal their features to me more, I hear in my head "Their called HELLHOUNDS darling~"

I watch as the three lick their lips, each of them have incredibly long tongues that reach out of their anthropomorphic faces, their lips look soft even as they hide the sharp teeth of their maw's. I watch as for a moment they all start moving towards my ass at once, then they stop... they stop? Their looking at each other now... W-wait why are they grinning like that?!

That's my last thought before a flash of light blinds me for a few moments, when it dies down and I can see again though? My jaw drops. Standing there. No, TOWERING there, LOOMING over me is an 11ft tall MONSTER! Black fur with orange streaks along her body, and finally deep red hair on top of her heads... HEADS?! WHY ARE THERE THREE HEADS?! "Mmm how's it feel to get some time away from guard duty Cerberus~?" THE FUCK DID THE SHE DEMON SAY?! CERBERUS?!

I'm pulled from my thoughts as I hear the three heads, giggle, chuckle and see the last lick her lips while a set of MASSIVE soft, paw like hands land on my ass. Their HUGE, nearly PALMING my massive ass while I hear the demon giggle from the other end of the room, followed by an "Oooh~" and then an ominous sounding trio of THUMPS, the last of which is almost DEAFENING in the quiet room. I'm treated to the sight of the mirror moving again, angling so that I can see what's just hit the... HOLY FUCK... Laying on the floor is this Cerberus's NUTS, a pair of bean bag chair sized balls, packed so FULL that there doesn't seem to be a single wrinkle, they look completely SMOOTH. Holy Hell... Her COCK... I wasn't expecting any of them to be nearly as big as the Demon herself, but Cerberus is over here with a 10ft long, monstrously FAT, bright red, human shaped cock!

I heard in my head from the demon again "Be honest with her, tell her what you want darling~" I found my body and mouth moving without me meaning them too. I pushed my hips back, my cheeks grinding into her paws and spreading wide open as a whimpering, pleading noise came unbidden from my throat. Two words left my lips, sounding like the most begging tone I could ever pull off. "Breed me~" And through the mirror I watched her cock finally hit full mast, barely able to lift itself enough to aim for my backdoor, I even HEARD her cum tanks slosh and swear I saw them swell just a few inches BIGGER!

A moment later and I can feel Cerberus pin me to the bed. Her hands holding me there as she began to push, I watched Korathi lick her lips, smiling in glee as that battering ram of a dick started to enter me, my ass stretching and relaxing to let her in. "Oh don't worry boy~ We'll give you EVERYTHING we've got~" I heard from the center head, "Mmm it's so rare to get to enjoy a boy like this, we'll have to enjoy you THOROUGHLY~" came from the head on the right, "I wonder, tell us boy... Do you want to take our KNOT~? Before you choose, let us give you a preview~" I heard in an almost SINISTER tone from the head on the left. Moments late rand my cheeks were being squeezed around their tremendous cock as they hot dogged me, pumping back and forth, working themselves up more and more.

I watched their enormous tits bounce in the mirror, watched their gigantic cock bounce and throb by looking up a little, then the show REALLY started... I watched as their knot inflated, I didn't know if that was as big as it WOULD get or not, I assumed it was but... Holy fuck it looked like a goddamn BOWLING BALL in terms of size! I suddenly was looking in Korathi's eyes as she bit her bottom lip and gently held my face with her hands. "Now now darling, tell the truth~" I felt it, she was using some sort of magic I think? It felt like what I truly wanted was being pulled to my lips, my eyes went wide and I blushed massively as the words left my mouth and registered in my head. "K-knot me! Give me a HUGE LITTER of Hell pups~!"

The worst part I think? Was that my mouth had practically moaned it out, even with several FEET of her gargantuan cock throbbing past my head no less. "Oh you are a REALLY good boy~" I heard her almost growl, a look in the mirror let me see that the right head was drooling a bit while the left head was practically FERAL and damn near foaming at the mouth! "Unfortunately I can't really knock you up boy, but if you become an anchor for my friend here? I could come back and pay you a PROPER visit~" I heard the center head behind me, licking her lips even as the left one got into my ear. "If I come back here to visit you boy? I'm gonna REALLY cut loose! I may not have the time to do so tonight, but you better look forward too it~"

That was the only warning I got as her hips suddenly yanked back, a split second later and I felt her gigantic fuck column of cock pressing against my entrance. Korathi did something with her magic again and I heard Cerberus let out a low moan. A look through the mirror showed me some sort of lube slowly covering her enormous cock. What follows over the next several minutes is that gigantic rod pushing into my ass slowly, inch by inch, one foot at a time, seemingly without END. By the time a fourth of her size is buried into me, my belly is bulging outwards massively, my ass feels tingly even as it squeezes and tries to encourage her to push DEEPER. By the time she was halfway inside, I was a moaning drooling mess that couldn't stop shaking. It wasn't just her tremendous SIZE, it was also the sheer HEAT coming from her cock, it was hot but not painful, almost like a relaxing but intense warmth that slowly spread through my body.

"Enjoying our warmth cutie~?" I heard from the head on the right. "Mmm it's to help make my BREEDING you easier~ It'll relax your body, and let me get so... MUCH. DEEPER!" I heard from the center head, until the end where the right chimed end only for the left head to GROWL out the final word as my entire world went WHITE. Why? Cause I felt their HIPS SMACK against my ass! Every inch, every last incredibly FAT inch of their cock had sunk into me, I couldn't help but stare at just how far my belly stretched outwards to take ALL of what they shoved into me. Then I felt her body climb up, over me, pulling out as much cock as she could befor- WHAM!

My eyes crossed and rolled up at the same time, my mouth hanging open in a silent scream of pleasure. Cerberus had suddenly DROPPED her entire weight onto me from above, her cock PUNCHING into my body and stretching me out RUTHLESSLY as my head was instantly smothered by her immense tits. Her powerful abs pressing and grinding against my back for a few moments before her hips YANKED back only to SLAM into me relentlessly, quickly working herself up to POWERFUL, SLAMMING thrusts and slowly getting FASTER.

Korathi's cock was towering over me, throbbing like a fleshy monolith as she watched the show and pumped a hand along her shaft. "Mmm don't worry darling~ Viola here is still just getting started! Besides...There's still ROUGHER, HARDER, BIGGER FUCKS to come~" As she spoke I was treated to the show of her body and especially her cock going through another growth spurt. I watched Korathi's cock reach a girth nearly as monstrous as Viola's! But the length, holy FUCK she was getting even LONGER! Her body was growing thicker and stronger as well, her voice became even more sensual and lust filled. "Ooh finally! I've been holding back all this growth for a WHILE now~! Mmm I won't lie darling, I've been making DOZENS of more deals whenever you went to bed~ I've got HUNDREDS of contracts and most are already fulfilled! To think I didn't even have to ask for their souls either! What a STEAL~"

Korathi was growing into a towering demon of lust and power, but Viola's thrusts were getting faster, someone even HARDER. Apparently she took Korathi's word of there being HARDER fucks as a CHALLENGE, and I was little more than a fuck sleeve for her to vent on. "Fuuuucking lucky BITCH! I'd MARK HIM right now if he wasn't already yours!" She growled out at Korathi, the demoness looking smug as could be, even with pleasure waves rolling through her body as she grew and absorbed all that power she'd been building up. "M-mark?" I managed to strain out, just barely. "It would mean I could come and visit you WHENEVER I wanted! I'd even be able to do some really fun stuff with you~" I heard her growl into my ears, all three heads starting to whisper promises of all the fun she could have fucking me into a cum addicted HOUND SLEEVE, how she would LOVE to have a boy she can call her CHEW TOY even as she knots him so hard that he forgets his own name!

My head is tilted up enough that they can take turns kissing and overwhelming me further with their mouths, which is easy for them not cause I'm a boy mind you, but because they have INSANELY long tongues! Seriously! The right head was able to curl her tongue from my ear lobe all the way down along my jawline to the LOBE ON THE OTHER SIDE! "I wonder how many times I could wrap my tongue around that cute cock of yours~?" I heard her whisper into my ear as her tongue pulled back, the center head giggling while they left promised to TONGUE FUCK my throat until I was so hoarse my voice would take WEEKS to recover!

The entire time their hips didn't stop moving, slowly turning into a furry blur as they pounded away at me and held back for as long as they could. The question is, do they lose control and suddenly knot me and try to pump as MUCH into me as possible or does Korathi have to...
