It had been three months since Riku had been transformed from the scrawny, skinny weakling he had been into the towering muscle god he was now today. His partner, Xemnas, had decided that Riku needed some valuable time to rest and recuperate from the transformation, which apparently took a while. Despite this, Riku still had sex with himself, sucking himself off, fisting his now engorged cock, and shoving dildo after enormous dildo up his ass to satiate his new found craving for giant monster cock.
Now, he was casually strewn across the his massive bed, made specifically for his own increased mass. His ass was impaled with a dildo made to be a massive horse cock, with a dogs not at the base, but still too small to satiate the hunger for cock. His dick was stuffed with bulging bicep and shoulder, blocking the soon oncoming surge of black, gooey cum that had replaced his formerly pearly white cum.
His shoulder brushed the pure gold Prince Albert piercing at his tip, while his forearm and fist scrapped and rubbed his jade coloured frenulum ladder piercings, that Xemnas himself had replaced after losing the old ones in his growth. His balls had also seen their fare share of piercing as well, with pure platinum rings going straight down the centre, ending with one right on the ring of his hole. His massive, dick sized and leaking nipples were weighed down by massive silver rods, each weighing around a kilo in weight each.
With another shove of his arm, his shoulder was forced into his piss slit, eliciting a scream of pleasure from Riku. Cum was blasted from every orifice, his nipples bunching up as his chest tightened and was drained of every last drop of cum. His ass seemed to contain still more cum from the intense fucking it had received three months earlier, and was squirted out around the massive dildo that his ass was clenched around.
As his balls tightened and were dragged closer to his body, despite the massive weight of them, he felt cum blast it's way up his slit, but get blocked by the cannonball sized shoulder blocking his slit. As he felt the intense pressure build to painful levels, he ripped his arm free of his engorged and puffy piss slit, and let out an intense scream of pleasure, as the whole room was coated with his cum.
As his orgasm died down, he opened his eyes to see that he had been soaked with cum, as well as the bed, floor and ceiling.
'Well, at least I know I'm efficient at what I do' he thought. 'But now I'm bored. What the fuck am I going to do?'
With that he jumped off the bed, despite his bulky mass, and started wading his way through the knee deep cum. Knee deep for him at least, with his massive ten foot tall frame. As he walked, he felt the cum being absorbed back into him through his skin, his puffy piss slit seeming to drink up what it had just shot out. Before he knew it, he was merely ankle deep in cum, his balls were swollen from producing new cum and absorbing old cum, and his frame had bulked up with another fifty kilos of new muscle. He thought he must have had over five hundred kilos of muscle mass, all thanks to his transformation.
Once he reached the door to his room, he decided to explore the divine Halls of Priapus. Despite living here for almost three months now, he had barely done any exploring. He had only wanted to explore his new body, test it's limits and attempt to satiate his still burning hunger for cock. He casually reached down and pulled the dildo from his sloppy man cunt, throwing it aside without a second glance.
"Note to self" he said out loud. "Get a bigger dildo."
While he had his hand at his ass, he casually fingered, and eventually fisted his new hole. He had never known the glories of a loose hole until he had been kidnapped by Xemnas to be transformed. He still did not understand most of the process, and had participated in transforming others in the time he had been a part of the cult, but still felt ignorant. All throughout the halls he found many piles of used dildos, pools of thick black cum and you could hear the noise of many people being converted as he walked. He stretched out the ring of flesh around his ass, pushing his insides as he did so to form a large, beautiful prolapse, which trailed on the floor along with his cock and balls, leaving a slimy trail of black cum and anal juices.
While he did this, he thought he might go to the gym and go for a swim in the pool. This was no ordinary pool, Riku though when he arrived, and he couldn't believe what he was seeing. A pool ten times the size of any Olympic sized swimming pool, filled to the brim with cum. Oh boy, this was going to be fun.
Without a second thought, Riku got a run up and dive bombed into the pool, sending cum flying everywhere around the room. Despite this, it slowly made its way back into the pool thanks to sloped floors, ensuring that no drop was lost. The cum was also different from what Riku had sloshing around in his beach ball sized balls. Despite being surrounded by it, and his power of absorbing cum, it was being absorbed. Even his dick wasn't having any go into the stretched out piss slit. Clearly, somebody didn't want to lose any of this cum.
Without another thought, Riku decided to do backstrokes, showing off any and all of his perfect manhood. His prolapse was still present, and trailed three feet behind him and leaking cum as always. After a couple of laps, he felt exhausted despite his increased stamina, and hauled himself up onto a ledge.
What happened next was all a blur. Something grabbed Riku's ankle and pulled him back into the cum, while he heard someone say "not so fast, mr. Muscle". As he got hauled back in, his head hit the concrete ledge and he fell unconscious.
As he opened his eyes, the first thing he saw was the roof of the Poole room. And then a large, phallic shaped object hurtled across his vision.
"Where am I?" Riku yelled, bolting upright from his laid out position in the concrete floor. "Who, or what are you?"
"You are still in the pool room, my dear boy. And I am the tentacle god Oozecum the Lustful. I am here to rape that deliciously loose ass of yours, and milk you of all of your cum."
And with that, Riku felt tentacles, each with a cock head at its end, wrap around his waist, wrists and ankles, and haul him into the air. A tentacock came up to his mouth, and, submitting willingly to the cock god, he opened his mouth to be violated fully.
He felt a tentacle snake it's way up his thigh, leaving a trail of pre up his leg, aiming for the loose ring of flesh that signified the start of Riku's gloriously loose fuck chute. As his prolapse was now gone, the tentacle had to make it to the ring of flesh before any thing fun happened.
Sensing that he would need a larger tentacle to pleasure Riku, Oozecum engorged the tentacle until it mirrored Xemnas's glorious pole of man flesh, and immediately penetrated a foot into the loose orifice.
With a howl of pleasure around the cock in his mouth, Riku's nipples shot their loads across the room, miraculously being caught by tentacles and being eaten up by the giant god. The cock in his mouth squirted what had been caught into his mouth, making him wish for more.
As if reading his mind, two large, yet slender, tentacocks rose and positioned themselves at Riku's pierced nipples.
Without warning, they shot forward, impaling the nipple dicks, moving around the heavy silver piercings in his nipples to the reservoir of cum help within his pecs. He thought it tickled as they squirmed around in his pecs, and he had more and more tentacle shoved into him, both into his chest and into his ass. The tentacles now squirming in his pecs started to suck up the reservoir of cum, which quickly replenished itself as it emptied. This cum was quickly funnelled down the tentacock and up into the two that now rested in Riku's whored up mouth.
The tentacle in his ass had reached his stomach, obvious to Riku by the massive squirming bulge now obvious despite his rock hard abs. As he looked down in wonder, the tentacle started to engorge until it became increasingly uncomfortable to have the cock up his ass.
'Ah well' Riku thought. 'Its not like we can have everything we want.'
As he thought that, large bulges started to move up the length of the tentacle. As they reached his ass, they stretched it beyond belief, and headed further into his body. It was obvious where they were going due to the large moving lumps moving through his intestines. Finally the first one stopped in his stomach, and he suddenly felt full, as if he had drunken too much cum in in round. As the bulges continued to move up his ass, his stomach started to bulge out further due to the increase in the movement of the bulges.
"I am now breeding you, filling you with my eggs. You will give birth to my young, right here in this pool, in three months time. These eggs will hatch inside you, and must be fed with extra strength demon cum. Your cum is just the right consistency needed, so you must drink wholly from your manhood to keep every one of my younglings alive."
All Riku could think of to say was "more, I need more in my ass." And that was exactly what Oozecum did. He sent another tentacle up to Riku's ass, which stretched his ass even more as it inflated to the same size as the previous one. Once it had reached his stomach, the familiar bulges started to flow through and started to get backed up.
As all this was happening, Riku's unattended cock stood at attention. Noticing this, Oozecum directed a tentacle to 'play' with this unattended organ. Within moments of the tentacock wrapping itself around the engorged, ultra sensitive head, did the tentacle penetrate the loose, sloppy yet still extremely sensitive piss slit, that was now considered a new fuck chute by Riku. The tentacle burrowed deep down into the cock, sending shivers down Riku's spine as it passed everyone of the piercings on his underside. The tentacle swelled to amazing proportions to keep Riku pleasured, and the underside of his dick swelled out further than anything had stretched it out to before.
With out warning a second cock joined the first, swelling again to the same size of the other one, just as the two in his ass had done. As the second caught up with the first, Riku felt the same sensation as the one in his pecs. The tentacocks were stuffing as much into each testicle as they possibly could, swelling each one larger than boulders. The tentacocks swam around freely through the inky black cum of his balls, sucking up as much of the cum as was possible, when it was replenished just as fast.
Soon, the tentacocks in his ass shrunk a bit to let in two more tentacles, each on already backed up with dozens of Oozecums eggs, ready to be placed directly into his glorious sac. The same happened with his pecs, though these stretched the nipple dicks wider, forcing as many large tentacocks into the opening as possible. They too had dozens of eggs already waiting to find their new home.
By now, Riku had started to feel nauseous after taking up so much cum and being filled with so many eggs.
After what seemed like hours of fucking, Oozecum slowly pulled out every tentacock out of Riku, and lowered him to the ground. As he slithered back into the black depths of the cum pool, he said "Remember Riku, three months. Three months, and you will be raped again by my young."
As he disappeared, Riku slowly got up, feeling bloated and full. He slowly walked out of the pool room, and made his way towards his room, grabbing a large dildo and shoving it up his ass along the way, in an effort to stop his sloppy ass from leaking its contents out into the floor. When he finally got to his room, he looked into the floor to ceiling mirror to assess the damage.
He now looked like a heavily pregnant woman, well at least one with a dick. His stomach looked like he had swallowed both of his and Xemnas's testicles, though it was all lumpy due to the shape of the eggs, despite the massive amounts of cum also present. His pecs now looked like breasts, due to the large number of eggs present there, which seemed to be growing due to the ever present cum. His balls were swelling quickly as well, and were getting rather uncomfortable, as the eggs grew even quicker then those in his chest. As much as litres of cum had been sucked out of him, it had all been shot back into him, as of to help the growth even more. Now, his swollen sac hurt from the torture it had been through.
Stifling a yawn with the back of his hand, he looked around and saw his bed, so soft, yet still soaking from his orgasm from before. He decided that his sudden desire to sleep rather than to fuck himself senseless again was more important, and hauled his enormous frame over to the bed.
When his head hit the pillow he was already sleeping. The force of the fall sent the dildo sliding out of Riku's ass, landing on top of his enormous, swollen sac of cum and god eggs. Slowly, a single tentacock crawled its way out of Riku's ass, trailing along the sensitive skin of his perineum, eliciting a low groan of pleasure from the muscle god. The tentacock reached the fallen dildo and wrapped around it, dragging the rubber length back to the loosened lips of Riku's ass.
As the head of the dildo arrived at the entrance to Riku's hole, the tentacock pulled the rubber cock in, balls deep in a single movement, causing Riku to buck with the pleasure. The dildo continued to move in and out, piston fucking Riku from the inside out, until his ass hole spasmed with multiple analgasms. As the orgasms subsided, the tentacock pulled the dildo back in balls deep, and quietly squirmed its way back up to Riku's stomach, where it's brood had started to hatch.
