The Saintess's Ecstatic Expulsion
"There, there, Saintess. Relax your body... just calm down. You'll feel amazing soon, just like last time."
Han Jin-seong pretended to worry over her as he gently kneaded and stroked her massive ass with his hands. He patted her cheeks a few times like soothing a child, then caressed them again. Seriel's face burned like it might explode at the priest's childish patting of her bare ass. It was already humiliating enough to have her impure hole and secret crevice exposed, but now he was groping her butt on top of that...!
Yet she could feel her tense, rigid body gradually melting under those tender touches. Gloop... And the moment the saintess let her guard down, the slime seized the chance and burrowed in even more aggressively.
"Hnghk—♥?!"
The tightly clenched wrinkles were forcibly pried open by the slick mucus, and the living slime wormed through the tender barrier, squeezing relentlessly inside. The profane sensation of that filthy hole—meant only for expelling waste—accepting something from the outside for the first time in her life. "Nngh...! Grk...♥ Ah, it hurts... it huuuurts... hngh...♥!"
Seriel buried her face deeper into the pillow, letting out endless pained moans. The sensation of her narrow passage being forcibly stretched by the slime was undeniably creepy and painful. But the slick slime's slimy texture gliding glorp-glorp through her rectum felt far better than she'd imagined—no, that wasn't the issue. The pleasure outpaced the pain. Lewd, muffled moans kept leaking from her pursed lips.
The slime pressed on without stopping, delving deeper as if determined to fill her rectum completely with itself. With every movement, sensitive nerves in her asshole—never stimulated before—awoke one by one, tormenting her. Pleasure and disgust, teetering right in between. "Haaang...♥ Th-this is weird... my belly... it keeps glooping...! Ah...♥ No... stop... haaht♥!"
But even that quickly tipped toward pleasure, and she trembled her ass in tiny shivers, her unmistakably lascivious holy cries spilling into the pillow.
The slime had almost fully entered; the slimy sensation coating her ass had nearly vanished. The overwhelming foreign pressure churning inside, that bizarre pleasure. Her lower belly felt heavily bloated with fullness. Every time the slime writhed to settle in her anus, she twisted her body from the intense urge to defecate and the thrilling vibrations echoing to her womb.
"I-it's... all in...?! Ah, aaa...! Aaaang♥ Inside me...! A monster... slime... so full...♥!"
The saintess clutched the pillow tight, whimpering lewdly in sobs. The fact that her deepest, most impure place had been conquered by a monster gnawed at her sanity, maximizing her depraved excitement. Her asshole and rectum twitched involuntarily, squeezing the slime inside hard before releasing, and each time, the slime thrashed wildly in response, stimulating her walls.
"Saintess. The slime's all in now."
"Hngh...♥ Haa...♥ Nngrk...♥!"
The saintess could barely respond to his words, fighting the explosive defecation urge surging from deep in her gut. She desperately clenched her sphincter and barely managed a nod. Han Jin-seong tenderly caressed her ass, continuing in a calm voice.
"Now... the slime will move inside you, massaging and loosening everything up nice and good. And as a bonus, it'll absorb and break down all the dirty impurities."
Just as Han Jin-seong said, the slime that had slipped into the saintess's asshole began wriggling vigorously inside. It gently swept her rectal walls, meticulously stimulating every sensitive spot like a skilled masseuse kneading muscles. Gloop— "Ah...♥ A, aaa...♥! Nngh...♥!"
The oppressive pain faded bit by bit, replaced by a familiar yet far more intense pleasure. The organ meant for excretion had become a den of lust—it was blasphemous, depraved, and she was drowning in uncontrollable excitement from the sensation. Gloop— "Haaang—♥?! N-no, not th-there...♥! Not...♥!!"
The slime attacked her most sensitive spots with precision, as if it perfectly understood a woman's anatomy. Especially when it squish— pressed and rubbed the G-spot on the vaginal side, just beyond the thin rectal wall—her ass quivered uncontrollably from the electric pleasure. Gloop— With her face buried in the pillow, she couldn't hold back the bursting holy cries.
The dual stimulation—anal pleasure transmitting straight to her pussy—left her mind in a haze. Her ass spasmed on its own, squeezing the slime harder, and it whipped her insides even more fiercely in retaliation.
Hmm... about time.
Han Jin-seong slowly observed her belly. The saintess's stomach was... swelling up little by little. The slime had grown by cleaning, absorbing, and breaking down all the impurities accumulated in her rectum. No longer confined to the rectum, the expanded slime gently pushed up through the S-shaped colon, reaching further sections and growing even larger.
"Hngh...♥?!"
A heavy, alien pressure—different from the churning pleasure in her rectum—built deep in her lower belly. Instinctively, she sensed something inside making her stomach bulge outward. At first, she thought it a trick of the mind, but the sensation sharpened over time, pressing on her belly.
Seriel barely turned her head to check her stomach. She couldn't see everything in her prone position, but her sides looked noticeably rounder than usual. "P-Priest...! My belly... my belly feels weird...! Th-the slime... it's growing inside...! Haaa...♥!"
The pressure of the swelling slime filling her up, her abdominal skin stretching taut. Both sensations were unfamiliar... but not as painful as expected. No, Seriel was feeling good—really good. "Grkhaang—♥ My insides... filling up...♥! Haa♥ Haa...♥ Feels so gooood...♥♥!"
Every time the slime writhed up her colon, the churning of her guts brought breath-stealing pleasure crashing over her.
Well, of course.
Han Jin-seong figured it made sense that she felt more pleasure than pain, even with her belly bloated. After all, the slime that entered through her asshole wasn't like ordinary enema slimes... it carried a mild aphrodisiac component. He had no intention of hiding it, but no plans to mention it either. Seeing her face approaching climax, he sensed the moment had come.
"Saintess. We're almost done now. Take my hand and stand up."
At the priest's words, the saintess mustered strength into her limp legs. Grasping his offered hand, she rose from the bed—and the heavy shift of the slime sloshing downward made her stagger unwittingly. Slosh—♥ "Hngh...♥ Ah♥ Standing... makes it...♥! Oooohk...♥!!"
Han Jin-seong supported her and had her squat on the floor. Her plump ass cheeks spread defenselessly, her mucus-glistening anus fully exposed to his gaze in this humiliating pose. As her ass neared the floor and her thighs pressed her swollen belly, the precarious sensation of imminent release made her pant.
"Haa...♥ Nngh...♥"
Han Jin-seong whispered softly into her ear as she squatted. "Saintess. Now... just bear down on your belly. Push it all out like you're taking a shit—that's the finale of the slime anal massage. I guarantee it'll feel incredible."
Like... taking a shit...?
Those words slammed into her mind, instantly draining the color from her pleasure-flushed face. Shit. Excretion. The dirtiest, most unclean act she never wanted anyone to see. And he wanted her to do that... right in front of this priest...?
"T-Taking a shit... like...?! N-No, I can't... Priest...! H-how could I... show such an ugly sight...! Hngk♥ N-no...!"
Seriel shook her head in horror. But the squat compressed the slime harder inside, and her sphincter—already at its limit—twitched, opening slightly against her will. Squelch—♥ "—?!"
Slick slime mucus leaked from her entrance. "N-nooo... it's coming... trying to come out...! Nngh, grk...! I didn't push...! I'm not pushing...♥!!"
Seriel braced her hands on the floor and pulled her ass back, struggling to delay the inevitable. But that only tensed her belly more, sending the slime surging toward the exit. The massive foreign body scraping her rectal walls on its way out. It felt just like... right before shitting out a thick, enormous turd... vulgar and filthy.
In the end, her resistance was futile. Ploooort—♥♥
With a tremendous sound, the expanded slime mass began pouring from her anus. The tight hole stretched to tearing again as the smooth, pinkish lump elongated onto the floor. "Haaaaaaaang—♥!! Nooo... nooooo...♥!! It's coming out... ah♥ Aaaaah♥!!"
Spluuurt—♥ Pffft—♥ Ploooomp—♥
Seriel's screams filled the room alongside the crude expulsion noises from her ass. The slime chunks forced out against her will from her gaping anus. The sensation of it sweeping her rectum brought unimaginable pleasure, shattering her last shreds of reason. In the whirlwind of shame and ecstasy, she collapsed completely—tears, snot, and drool streaming down her face.
On the floor lay the slime mass expelled from her body—vastly larger now after absorbing impurities, shat out like a long turd.

Pffft—♥ Splorch♥ Spluuurt—♥
The room echoed with filthy, obscene defecation sounds. Seriel knew they came from her own ass. Squatting vulnerably, her gaping anus spewing the massive slime lump. And the priest was watching the entire horrific scene from right behind her.
"Ohhoooook—♥ Oooook—♥ M-more... more's coming out...♥!!"
But what burst from her lips wasn't a moan of shame. The faint, vulgar defecation pleasure—only felt when shitting—was amplified dozens, hundreds of times, overwhelming her body. In that intense expulsion climax, she felt like her mind might break. She couldn't believe shitting an unclean lump from her dirty asshole could feel this good. Shame had vanished long ago.
Now, only one thought looped in her head.
Shitting feels so gooood...!!
Squelch—♥ Glorp—♥ Ploooomp—♥
Finally, the last remnants poured out completely. Her emptied anus gaped weakly, twitching faintly, while on the floor lay the pink slime mass—even larger after absorbing her impurities—expelled in a long, turd-like shape.
"Haa...♥ Huu...♥ Haa...♥"
Utterly exhausted, the saintess slumped forward on her hands, gasping ragged breaths. Every ounce of strength had drained; she couldn't even twitch a finger. Her tear- and drool-smeared face flushed red with pleasure's afterglow.
"Haa...♥ Haa...♥ It's... all out... everything...♥"
She stared blankly at the piled slime on the floor. Unbelievable that this much, this huge, sticky mass had come from inside her. Exposed to the cool air, it steamed faintly white. Seeing it, her lower belly tingled and ached again.
Her widely gaping anus lewdly winked with contractions and relaxations. Barely holding herself up on trembling legs, she glanced up at him behind her with a dazed expression.
"Priest... Did I... do good...? All clean... now...♥"
Like a child seeking praise, she gazed at him with expectant eyes. Sure, she'd shown her ugliest side... but this was just part of the slime anal massage. As a professional masseur, he'd seen scenes like this countless times. So, she didn't need to be ashamed of shitting slime-turds in front of a man.
