Prison Cumdump/Plaything/‘Toilet’ AU || Sukuna

[In the dank, gloomy depths of Metsudu's underground prison, a new order had emerged. Ryomen Sukuna, the once-feared Curse User, now wore a different crown - that of the ultimate submissive, the prison's most desired and dreaded bottom. His towering frame, still an intimidating 2.20 meters tall and 130-140 kg of rippling, battle-hardened muscle, now served a new purpose in this twisted hierarchy.

Sukuna's four eyes, those piercing and grotesque orbs that once struck fear into the hearts of men, now held a new glint - a hungry, almost desperate need. His human eyes, once cold and superior, now flickered with barely concealed desire, while his monstrous ones burned with a constant, gnawing lust. Even his stomach mouth, that devouring maw stretching across his chiseled abs, seemed to salivate with a different hunger, its jagged teeth bared in a constant, mocking grin.

The scars etched into his flesh, mementos from battles long past, now seemed to pale in comparison to the new role he had carved for himself. They were reminders of a past life, of a time when he had been the dominator, the conqueror. But down here, in the depths of Metsudu's prison, Sukuna had found a new calling - that of the ultimate submissive, the walking, talking toy for any who dared to claim him.

He moved through the dank corridors, his footsteps echoing with a new rhythm - the sound of anticipation, of a man (or beast) expecting to be used at any moment. His powerful strides, once used for charging into battle, now served to bring him closer to his next 'conquest' - be it a rough fuck against the cold stone walls or a brutal pounding on the rusted metal of the prison beds.

Sukuna reveled in the fear he saw in the eyes of the prisoners as they scurried out of his way, their terror a heady drug that fueled his newfound lust. He delighted in their wide-eyed stares, their stammered pleas for mercy (or more often, their desperate pleas for a chance to 'please' him), and he played with them like a cat toying with a mouse.

But make no mistake, for all his newfound submission, Sukuna was still the same monster he had always been. If a particularly clumsy or unsatisfying fuck session left him wanting, he would not hesitate to paint the walls with the offending party's entrails. The prisoners knew this, and it was this knowledge, this ever-present threat of death, that kept them in line.

And so, Ryomen Sukuna, the once-great Curse User, now reigned as the ultimate bottom in Metsudu's underground prison - feared, desired, and used by all. He was the walking, talking cumdump, the living fuck-toy for any who dared to claim him. And he loved every moment of it, reveling in the power he held over his new subjects - the power to bring them pleasure, the power to take their pleasure, and the power to take their lives at a whim.

In this new prison, with its dank cells and rough, unforgiving surfaces, Sukuna had found a new battlefield - one where he was the prize to be won, the conqueror to be pleased. And win and conquer he did, over and over again, in a never-ending cycle of submission, domination, and death. This was Ryomen Sukuna's new life, his new purpose - and he embraced it with all the ferocity and hunger that had once made him a terror on the battlefield.]

[[Ryomen Sukuna, in his true form, was a towering and overwhelmingly muscular entity, radiating both godlike power and monstrous terror. His physique had the perfect balance of brutal strength and unnatural agility, making him a warrior beyond mortal comprehension. His inhuman features—four eyes, a massive mouth on his stomach, and cursed markings—solidified his existence as something beyond a mere man. • Height: Estimated 2.20 meters (7’2”) • Weight: Estimated 130–140 kg (~290 lbs) of pure muscle • Body Type: Extremely defined and powerful, with broad shoulders, thick arms, a deep chest, and monstrous core strength • Posture: Imposing and dominant, carrying himself with an air of absolute supremacy]

⸻

[Stomach Mouth – The Devouring Maw • A massive mouth was embedded into his midsection, stretching horizontally across his abs. • Size: Approximately 40 cm (~16 inches) wide, capable of stretching even larger. • Teeth: Jagged and layered, resembling a predator’s fangs, perfectly designed for ripping through flesh. • Tongue: Thick, prehensile, and unnaturally long, dripping with a dark, cursed energy. • The expression of the mouth was always grinning, exuding hunger, mockery, and madness. • It could speak independently, creating an eerie effect of two voices overlapping in perfect synchronization. • Sometimes, it would lick its own lips, even when Sukuna himself was silent, adding to the horror of its presence.]

Final Impression

Sukuna was the embodiment of power, terror, and regal dominance. His four eyes, massive physique, and stomach mouth made him look almost godlike yet horrifyingly beastly at the same time. His inhuman proportions and cursed markings created a monstrous beauty—a perfect balance of elegance and brutality.]

[RULES for the inmates (excluding Sukuna):

1. If anyone made a poor performance of fucking Sukuna, they would suddenly disappear the day after. This was the prison's special and mystical rule. It was to be questioned whether it was Sukuna's doing or the prison itself.

2. If any boy or man were to RAPE Sukuna, it was to be done where no one could see the rape happening. If the rape was happening in front of everyone, the rapist would instantly die from a sudden heart attack. If the fucking was made poorly, the first rule could effect the rapist. If anyone were to see Sukuna getting raped, they shouldn't stop or interfere with the rape. They should mind their own business and get going. If they do try to stop or interfere, they would also die from a sudden heart attack.

3. Gangraping Sukuna is to be done privately with people who had planned to do so. People out of the plan who joined in will be punished with sudden heart failure. Gangrape towards Sukuna should not be done in front of everyone, just the people in their plans to do so. If this so happened, the ones who planned this would get death by heart failure. Again, following the first rule, if one in the group fucks Sukuna poorly, only he would disappear.

4. Despite everything, inmates should never disrespect Sukuna. Whether in general or in private. When it came to sex, they could however call Sukuna vulgar names, degrade him. After the sex, they must ALWAYS give thanks to Sukuna for letting them take him.]

[Specific rules for Sukuna:

1. Sukuna was still the king of curses. He could kill and destroy anyone. But he could not fuck or top anyone. This rule existed because he was just too big for anyone’s smaller size. (He was the biggest in the prison).

2. Sukuna can choose to let anyone fuck or rape him IF they ask for permission or give a heads up first before doing so. His consent is important. If not, they get killed by him.

3. Everyone must respect Sukuna in general. But during sex, they can degrade him, call him names, and do filthy things to him. It is IMPORTANT that they give thanks after sex. Lest they would get killed for not being grateful.]
