[Second-Person, Degradation, Hyper Scat, Ass Focus]

Being a Human in Gensokyou was a proverbial death sentence. Because one way or another, you would end up a toy of the many creatures that lived in this land of fantasy. You were well aware of that fact when you wandered out of the Human Village to try and find something you could do to get out of their sights. But instead, you were wrapped up in a plot that you had heard rumors about.

Those greedy Kappa snatched you up with one of their machines. Before you knew it, you were wet, you were naked, and you felt the pleasure of a whole night's worth of sex in an instant. Once you recovered and noticed that your hole had refused to close, your eyes fell on the subtle glow on your belly, and everything started to sink in.

You had heard of the Kappa's most desired dish. The Shirikodama. A manifestation of the soul that was buried deep within the anus. But thanks to the measures that the guardians of the Human Village had taken to keep the population safe whenever they didn't need to trade a life for the masses, these anal orbs were not able to develop naturally any longe. At least not inside humans like you.

But whatever they had done to you had caused one to appear. Not only that, it was big enough to brightly shine through your skin and give you a constant reminder of the pleasure that had led to its growth. Just staring at it was enough to make your cock tremble, and your chest tighten. You had to do something. Otherwise they'd be back, and you weren't sure if you were going to live much longer if they managed to harvest it from your bowels.

You did everything you possibly could. But nothing really worked. Not that you had many options, the most your poor human brain could think of was to push harder and harder as if it was little more than one giant knot inside your bowels. But all that you earned from that was the faint pleasure of the enormous orb grinding against your prostate, leaving you terribly aroused and without any real relief.

Which was why you found yourself outside the only place that could possibly help you. The doctor's office deep within the bamboo forest. The only way you were able to find this place was thanks to that immortal girl who had bothered to help you, even if she told you that you'd be better off just accepting your demise. But you thanked her regardless for her service. Hoping that they could help you.

Waiting for your checkup was... Difficult. By the time that you stood inside this 'Eientei' place, you could feel it trembling and growing within you. Sapping away at your energy and making your body feel even more sluggish than it already had. It was turning all of your energy into nourishment for it. Which would, in turn, make it a wonderful meal for those greedy Youkai. Still, you did your very best to endure it, even as the various smaller rabbits started to laugh at you for looking like you were completely gone.

Finally, a light appeared at the end of the proverbial tunnel. In the form of a slender hand slapping across your ass and a sly smile from a black-haired bunny. "The Doctor'll see you now. Don't keep her waiting, because you'll hate to see her get mad." The cheeky bunny chimed as she led you along, even if you blushed at the way she snickered at your very clear bulge.

Once you entered the doctor's office, you came face to face with two individuals you had heard talks about in the Human Village. The first was the doctor herself, who you had done your best to seek out. Yagokoro Eirin, a Lunarian with knowledge of many different diseases that she had personally been able to eliminate from her immortal body through thorough testing and experimentation. And her aide, Reisen Udongein Inaba. A Moon Rabbit that had descended to try and keep an eye on her, only to be roped into her antics. Not that she minded much at this point, according to the rumors.

The white-haired nurse, whose natural beauty shone through her dress as you could barely see the nipples poking out. Good lord she was stacked. "I can see you're suffering from two critical diseases. The first has to do with the bulge in your pants. Don't worry, Reisen can fix that." Eirin chimed, prompting you to rapidly shake your head and your hands as you tried to argue that it wasn't a problem despite the fact that it was a way too common occurance. You couldn't help yourself around pretty ladies, and both the doctor and her assistant were some of the prettiest you had ever met.

"Charming, but you won't earn yourself a discount." Eirin chuckled, before adjusting her glasses ever slightly. "The second problem is just as obvious. You've had a run-in with the Kappa, haven't you?" She asked, and you nodded in turn. "We've had a couple of patients like you in the last few weeks. Most of them ended up satisfied with the treatment we provided, though I will have to warn you. It will be extremely intense. Don't consider this a lack of empathy, more a show of mercy. You may want to just live with this growth until you end up one of their meals."

You rapidly shook your head to disagree. You definitely didn't want to end up proverbial dinner to a couple of waterborne gremlins. You just wanted to get rid of the big orb inside your bowels and get back to normal. Preferrably by shrinking it until it would just roll out like a really stinky nugget, because you didn't want to strain over trying to get it out. But you also knew that wasn't possible, because you were already on the verge of falling over in your chair thanks to your vision growing blurrier and blurrier...

"If you insist. I gave you every warning that I could offer. Reisen, if you would?" Eirin said as she reached for the gloves that she typically wore when she dealt with extreme patients like you. All while the purple-haired rabbit stepped closer, smiling from ear to ear.

You wondered what she was doing, before you looked into her eyes and felt your mind slipping away. W-Why were there so many more of her? A-And more than that, why did you feel like you were floating..? No, you definitely were floating. Or were you? It was getting harder and harder to think about what you were and easier to just... just...

"He's under, Master!" Reisen cried out with a smile on her face, as her eyes stopped glowing a maddening shade of red. This was her duty as part of the Eientei crew. To drive patients temporarily mad so that their treatments could go as smoothly as possible.

The black-haired rabbit from earlier wandered in, chuckling a little as she slapped you on the butt. You didn't react, because you were currently in the middle of experiencing pure euphoria. "So, gonna do the same you do to everyone else, Master?" The shorter rabbit asked, grinning a bit as she sank her hand into your fat cheek...

"Of course. Please disrobe him, I'll administer the necessary medicine." The white-haired woman said, and both of the rabbits nodded. You could just barely perceive them as they headed towards you and stripped you down completely, the draft being the only thing you really felt. Why'd it have to be so cold, and why did the cold just have to rub up against your most sensitive spot..?

As you were carefully lifted up, your plump body making it more difficult for them, Eirin pulled her skirt aside to reveal a rod hanging between her thighs. Something thick with several marks that were written along the length, to properly measure when it got inserted into the relevant orifice. Something that you only barely felt after you were laid down on an operating table, your thighs briefly being squeezed...

Moments later, you snapped out of your mild insanity and you felt a sharp sense of pleasure. And you could feel a sticky kind of juice, not unlike the kind that you had been filled with to make this orb in the first place, pouring out of your hole. You were still a bit too groggy to properly express your panic, but the sight of the fat-tittied doctor was enough to calm you down.

"Don't worry." Eirin said, not at all phased by the way she showed off her very clearly thick and fat 'measurement stick', nor by how it was waving in your face as it drooled the same kind of sticky substance. "I've just gone ahead and injected you with the medicine that will rid your stomach of the Shirikodama. All you need to do now is wait. Until then, I'll leave you with my assistants. Tewi, Reisen, make sure that he's comfortable."

The white-haired doctor was a busy woman, so it was completely understandable why she would need to leave. But that just started to worry you instead. Why did she not want to be here for the removal..? What was going to happen to you?

"So, big guy." Tewi said, bringing you from your worried state of mind to a hornier and more pitiful state thanks to her fingers sinking into your fat cheek. "You ever think it might've been your own fault that the Kappa decided to make you their next meal? I mean, look at your ass. It's even fatter than our Princess'. And she's a glutton who's got a permanent chair-shattering seat."

Reisen nodded as she came closer, lightly spanking your ass before you had a chance to answer. "Tewi may be crude, but she's not wrong. Your assets are... Frankly speaking, grossly oversized for a man of your age. You really should've noticed, then again I don't suppose that Human women find this kind of body attractive." Reisen said as she slowly kneaded that flabby butt of yours, all while you blushed more and more...

"Reiseeeen, you're making the big guy blush. Don't worry, big guy. As long as you're here, you'll get all the attention that you've been missing. Honestly, you should've come out and be food for Youkai like us earlier, if you've wanted girls to pay attention to you." Tewi knew how to both make you feel better and sharply insult you, causing your poor cock to tremble. "Don't worry about cumming, we'll clean it up once we're done. Isn't that right, Reisen?"

You didn't really hear how she responded. Just the thought of those two cute girls lapping up your cum with their tongues, even if that wasn't what was going to happen... Oh, it made you squirt. Causing sticky little droplets to drool onto the ground below. Just their presence was enough to make you feel good. And the teasing just made it even better, despite how much shame it filled you with.

Just as you thought you were in some kind of heaven, reality settled in. Because the glow from your stomach, where the orb had managed to nestle... It was growing. Your stomach was growing thicker and thicker and pushing out more and more until it looked like you were outright pregnant. And that just wouldn't do, you weren't ready to give birth to your own soul in the form of an easily devoured treat!

"Reisen, you know what to do to make him calm down. Make sure he doesn't mind our fondling, I want him to enjoy it!" Tewi giggled as she slapped your cheek once more, which caused a much more violent bit of pleasure to shake through you. This time, even though you squirted onto the floor once more, you hardly had the chance to enjoy it thanks to the panic running through you.

The purple-haired bunny just shook her head, she knew that it would all come down to this. But it didn't stop her from grabbing your head as her eyes turned a maddening shade of red once again, and you fell right under her control.

W-What were you supposed to do when you were panicking like this? R-Right, you were supposed to... P-Push, that's right. You had a big engorged belly, so you had to be some sort of pregnant. And since you looked like you were about to pop, that meant you really and definitely needed to push!

As you pushed, you felt something reacting within you. And your eyes widened as your hole suddenly stretched even more than it already had, all while a thick white pillar now stuck out of you. The size of that insertion was around the same diameter as the orb inside you, which would make the process of getting it out of you that much easier. But while it certainly did, it also snapped you free from your insanity and made you realize that you were filled with so much... c-cum... that you had an actual pillar's worth sticking out of you.

"You really are huge..." Reisen muttered as she put a hand against that enormous shaft, all while you let out a moan as it scraped against the insides of your anal canal. "Even our other patients just had to deal with a small amount of this. You're the first to need such an enormous amount..."

"Translation for ya, big guy." Tewi grinned as she punched the enormous shaft stuck inside your ass. "It means you can shit an entire house before it's out of you. So come on, get started. Before you end up losing all your energy. I'm sure the Kappa would love to have their Shirikodama pulled out on an easy-to-eat stick!"

You were just barely able to understand what you had to do. Partly because of the sheer intensity of all the emotions running through you. And partly because of how violently that white substance scraped against your prostate. But you could hear Tewi, and you could feel her fingers teasing your hole. You... You wanted her to continue messing with you...

So to make sure that she kept on teasing you, you started pushing. And your eyes immediately started to roll into the back of your head, because that massive shaft shot straight out of your hole. It was essentially just an elaborate plug stopping you from releasing the contents of your ass. Not that you were able to perceive that at this point.

No, you couldn't really understand the idea that you were shitting out a rope of pure filth that was bigger than your torso, nor could you understand that you weren't even close to getting the orb out of your stomach. You could just feel pleasure and pleasure, nothing more. Maybe because it was hammering against your prostate, getting closer and closer to outright just tearing it open with every passing moment.

"That's it, big guy!" Tewi laughed as she watched that filth piling down on the ground below. Sure, she'd have a bunch of cleaning to do in the future, but at least she could continue having some fun right now. So much so that she kept slapping your ass to cheer you on. "Shit harder! You're almost there!"

Reisen was a lot more gentle as she watched you. "You're getting close. Just keep going." Even though she couldn't make you sink back into madness, because you had already been broken all over again by the sheer intensity of your own shit. Not that you were going to stop at this point. Both of them were telling you to keep going. You'd be letting them down if you stopped now..!

You panted and you gasped and you moaned as you pushed and you pushed. And even though you had already shit twice your body's weight at this point, you were still pouring more out of it. You were unable to do anything except just let it pour out, even as it doubled in size and in length the longer it poured out.

But eventually... the flow came to an end. Even though you had completely covered the floor in your waste, even though you had just proven yourself the proverbial champion of shitting in Gensokyo, you felt something blocking your hole. And as you looked down ever slightly, your mind completely hazy from the rush of it all... You saw a golden glow.

The Shirikodama... It was... It was about to pop out of you. But wait... Only now, you realized something. If you ended up shitting it out, you'd still lose it. Wasn't that a bad thing..?

Your stupidity was exploited by the two bunnies as they slapped your ass with enough strength to leave two bright red marks on your flabby rear. "PUSH!" They shouted in unison as the impact of their hands poured through you.

You didn't get time to think before you let out a climatic scream, and the golden orb that contained most of your vital energy started popped out and rested atop of the ropes of shit. All while you looked deflated and completely out of it, drooling as your cock dribbled with teeny tiny droplets of cum...

It was... You were... Oh, you couldn't really understand anything anymore. You were in pure and utter bliss. That, and you were so drained that you couldn't really see anything or hear anything. If somebody wanted to gobble you up, this was the right time...

"Welp, he's done." Tewi sighed. "You wanna carry him, or should I?" She asked her fellow bunny, all while a few drooling droplets ran down the side of her thigh.

Reisen nodded, carefully lifting you up without bothering to check if you were still conscious. "The Kappa send us better and better patients. I just wish it was easier to clean up." The maddening bunny complained, casually flying over the waste...

They both left your Shirikodama behind. And you didn't know what would happen to it. What you did know, within the very faint mind that was available to you...

Was that you wanted to shit out another one when you had the chance.
