Rite of Corruption

From that point on, Aery's training proceeded steadily.

Her absence at night wasn't an issue at all. She was already handling the perimeter surveillance single-handedly anyway.

Reflecting on the first day, he made sure to have her remove all her clothes. The sweat soaked into them could potentially cause discomfort.

He never skipped the nightly intestinal cleansing, making sure to repeatedly bring her small body to anal climax, letting it seep in deeply.

"How is it? Any pain?"

"Nn, ku… uu, fu, unn…! N, fu… 💕"

"… Seems fine."

By the second day, she was already taking two fingers, and while her nipples were being toyed with, Aery thrust out her ass and reached climax.

The anal folds that had only clenched tightly on the first day now softened, wrapping around the fingers as if sucking them in.

With the effort of loosening her anus no longer needed, Yoal focused on locating Aery's erogenous zones.

Taking his time to thoroughly probe her anus, he found that the wall of her intestines which separated her anus from her vagina was particularly sensitive.

If he focused on rubbing that spot with two fingers, Aery would quickly heat up her body and writhe in agony. The moment he lightly teased her clitoris at the same time, she twisted her small butt and indulged in anal orgasms over and over again.

She still couldn't reach climax from anal stimulation alone, but that wouldn't be far off.

The concern was Aery's stamina, so he decided to skip a day every two days.

On the third day, he didn't just use fingers but thoroughly licked her anus with his tongue.

Thanks to the intestinal cleansing, there was almost no odor or dirt typical of an excretory organ — just the sweet feminine scent.

"N-No, Yoal-sama, don't… such a filthy place—ah, aan, a, haaa… 💕"

"No, no… inside, don't put your tongue in there, no—aan, uku 💕 n, u 💕 ku, fuuu… 💕"

Lost in the fresh pleasure of her inner walls rubbing together, Aery twisted her lower body and writhed wildly.

He licked and slurped noisily, sucking on her innocent anus as if to devour it.

He persuaded her as she protested in shame, coaxing and soothing her into acceptance. What do you think the cleansing was for? It's not embarrassing; loving your anus isn't infidelity — and so on.

It didn't take long for her to fall. After all, he'd already witnessed her defecating multiple times. Her psychological resistance was practically nonexistent by now.

With both hands free, Yoal licked and sucked her anus while relentlessly tormenting her nipples and clit.

The more she learned pleasure from those lewd protrusions, the more her anal sensitivity developed against her will.

While her asshole was being probed with his tongue, Aery sobbed and wailed through more than a dozen orgasms from her clitoris and nipples that day.

It was to the point that just using his fingers was getting tedious by now.

The next day, Yoal brought out a new tool with that thought in mind.

It was the slime mass used for intestinal cleansing and shaped for anal play. It was like a string of beads: a thin thread-like slime with multiple spherical slime blobs connected. The surface had fine grains that would stimulate her rectum with small vibrations.

As usual, after loosening her ass hole, he inserted them one by one, and the effect was immediate.

"A… a, kku, this…! This is no good… my butt, it's going to break…! My butt, it won't fit anymore…!!"

"It's fine. It's all in now. How is it?"

"… A, a, this… please, Yoal-sama, pull it out, pull it ouuut… my butt, it's so tight… 💕"

Contrary to her words of distress, Aery thrust up her plump butt and let out a sweet, sugary voice.

When he shook the base that acted as a stopper, her slender hips trembled jerkily. Thick love juices dripped viscously from her slit, sinking her into a swamp of lust.

Yoal observed the girl for a while in that position: upper body bowed down, butt thrust up.

Her dazzlingly white nude body was covered in pleasure-sweat as she twisted her ass about with a melted expression on her face. When he stroked her head, she smiled with relaxed cheeks. When he pinched her nipples, she stiffened and savored the sensation.

When Aery's breathing became shallow, rapid, and desperate, Yoal hooked his finger on the stopper protruding like a tail.

"Alright, pulling it out. Slow or all at once — which do you want?"

"… A, aku, n, fuu… 💕 S-slow… please do it slow…!"

"Yeah. Of course."

Of course, he had no intention of going easy.

The slime blobs were about the size of a man's thumb, but what stood out was their elasticity.

They yielded to her intestinal wall's clench without losing shape, yet without injuring her anal flesh. The tiny grains on the surface scraped at Aery's rectum with a unique bounciness.

He pulled the spheres out ever so slowly, making sure she fully savored the sensation of excretion. When about half was out, he twisted it as if kneading her anus while pulling.

Nyupun, nyupu, nyupu. Expanding and contracting her melted anus, Aery squeezed out each sphere one by one.

"Hii, kuu…!! A, a, my butt, my butt hole, it's going crazy… 💕 Slow, slow is no good… 💕"

"Then should I pull it all at once?"

"N-No, all at once is no, no go—nhiii… 💕"

He gripped the base firmly and yanked out just one sphere with force.

Nyupon! It popped out with a lewd sound. Transparent, odorless juice splattered, pattering onto the sheets and making stains.

In that instant, Aery shook her thighs convulsively and reached a light climax. Love juices sprayed from her gaping vaginal mucous membrane, scattering.

"What now, Aery?"

"… S-Slow… please do it slow… 💕"

"Got it… Make sure to clench your ass properly."

Yoal slowly pulled the slime blobs again, scraping against the insides of her ripe ass. Aery strained her butt desperately, trying to excrete on her own.

Her soft cheeks tensed and the foreign object peeked out from her blooming bud. When she pushed, nyupon! The slime blob popped out with a sound.

Aery sobbed from the overwhelming pleasure, her anus spasming open and closed. Love nectar dripped endlessly from her and the area around her feet was soaked.

"I-I can't… anymore… strength… Yoal-sama… I'm sorry… 💕"

"—Can't be helped."

Aery relaxed her shoulders, collapsing her upper body.

Yoal ruffled her head messily and slowly pulled out the slime blobs again.

Nyupon, nyupo, nyupu. The elastic spheres tormented her anus one by one, stirring it up as they exited.

"Good job. This is the last one."

"… Fa, hahi… thank you… 💕 Hii, nku, uu 💕 nu, fu, uuu… 💕"

Nyupun—the slime blob pushed through her anal ring and emerged. The connected beads, wet with lewd juices, glistened in Yoal's hand.

When she had excreted everything, Aery was already gasping for breath. She buried her small silver-haired head in the pillow, shaking her head as she writhed and cried.

Her twitching flower gate closed right back up. Despite all the torment, Aery's anus remained a clean pink, as modest as ever.

"Ha… a, n, u… fu, uuu… 💕"

Aery basked in the afterglow of anal pleasure, her petite chest slowly rising and falling.

Yoal gazed at her thoroughly used anus for a moment, then pressed the slime mass back against her hole.

"… N… ha, a… a, fuu… Yoal, sama…?"

"We've got time, so one more round should do."

"Eh, a, hi—no, my butt will go crazy, break, brea—ahiii… 💕"

Tsupun, tsupun—he inserted the spheres one by one. Aery's anus accepted them easily, clenching tightly as if delighted.

After that, the cycle of excretion and insertion repeated three more times.

Aery made her adorable pucker spasm, even leaking urine as she was launched into waves of depraved ecstasy over and over.

 

 

The following day, during the daytime, a slight change was noticeable in Aery.

She must have noticed the changes in her body. But since it wasn't a definitive discomfort, her behavior in front of others remained completely calm. She showed no sign of telling anyone.

Perhaps it was her consideration not to worry her master.

Charlotte's search on this side continued, but for now, there was no danger of being discovered. It was worth the effort of thoroughly setting up the deception spells.

That said, dragging it out too long wasn't wise either.

The next night — meaning the fifth day of training — Yoal decided to go for the finish.

"Relax. Keep your strength out. Got it?"

"… … … … Yes."

After completing the usual intestinal cleansing, he laid her white nude body on the bed.

Without even needing Yoal's instruction, Aery pertly thrust her adorable butt upward.

Her anus was already loosening softly. Her entire lower body was flushed with heat, faintly tinged with a rosy hue. It was a sign that the girl's body had learned lust and fully adapted to the lewd acts. This was precisely the fruit of the training up to today.

Yoal first thoroughly caressed her anus, pushing and pulling with his fingers, as he kneaded in circles. He hooked his fingers on the edges of her melted ass hole and spread it wide left and right.

"N, fu… n, nfu, u… 💕 N, ku, afu… 💕"

"Good reaction. You're already starting to get wet."

"… Yoal-sama, please, don't say—a, a, breath, breath, no, that's…!!"

He blew his breath into her wide-open anus. In that instant, Aery lost her words and clenched her hole with a shudder.

Peering into her tightly narrowing rectum, he blew his breath again. He forced her to repeat the sudden clenching and opening multiple times, making her anal folds flexible by compulsion. It was obvious that the more it moved, the more flexible it became. The hole was no exception.

"A, a… n, ku… 💕 Tongue, I like it… it feels good… don't suck inside, not there, being sucked…! A, aaa… 💕"

When her vaginal walls were thoroughly moistened, Yoal kissed the girl's anus. He crawled his tongue stickily from the surroundings, savoring the feel of her anal wrinkles, and eventually reached the bud.

Using her love juices as lubricant, he lightly prodded the delicate bud with his tongue. When he applied force, Aery's melted ass hole easily welcomed the man's tongue.

He then diligently licked her rectal walls, slurping up the transparent lewd juices. His lips sealed tightly without gaps, sucking intensely enough to make lewd watery sounds.

Feeling the sobs enter Aery's voice, Yoal thoroughly probed her ass hole with his tongue. He pistoned it back and forth, nyupo nyupo rubbing mucous membrane against mucous membrane.

"It's gotten quite soft… The inside of your ass hole is a pretty pink too."

"… A, hi… d-don't look… please don't… 💕"

After licking until threads of saliva trailed from her anus, Yoal finally pulled his lips away.

When he spread it with a kupa, the glimpsed rectal mucous membrane twitched and undulated endlessly, glistening wet with lewd juices.

This was enough loosening.

Next, he heightened her anal sensitivity. Aery's rectal mucous membrane was already a thoroughly melted erogenous zone, but it was preferable to make it flush with pleasure. To maximize the sensation during insertion.

Yoal aligned two fingertips and slowly thrust them into Aery's anus.

They were accepted with almost no resistance, enveloped by her rectal walls. He rubbed the front wall of her anus thoroughly with the pads of his fingers, inserting all the way in.

"… A, a, aku…! N, uu…! Fu, uu… 💕"

"Hm. Feels good getting probed deep in your ass hole, huh? Keep feeling it just like that."

"… U, n…! Ku, nuu…!!"

Aery beaded sweat on her forehead, writhing in anal pleasure as she bit down on the pillow. It seemed to be her habit. The pillow ended up with teeth marks, but since her reactions were easy to read, he had no complaints.

He slowly moved his fully inserted fingers back and forth, kneading the folds deep in her rectum. He thoroughly made a path deep within, acclimating her to the stimulation of friction and pressure.

The tight clenching of her flowering ring was a sign of impending anal orgasm. If he caressed her protrusions at the same time, she would easily reach climax, but Yoal eased off there.

Leaving his fingers inserted deep, he stopped and gently reached for her nipples.

"A, fu… 💕 N, ha… aa, a… ha… 💕"

"Don't move your ass. Stay still."

"A, kuu…! I-I'm sorry… 💕"

He gently pinched her nipples, rolling them squishily.

Aery immediately quickened her breathing, mewling in a nasal voice. Her spine tingled sweetly, and she trembled her butt.

The shaking of her soft cheeks was likely an unconscious action as her anal flesh clenched tightly on his fingers, but Yoal still didn't move them.

He persistently plucked at just her nipples, kneading them, toying until they hardened into stiff points.

"Ha… an, a, a… 💕 Haa, a… 💕 Fuu, n, kuu… 💕"

For amusement, he fondled her modest breasts, firmly erecting both nipples to their limits.

Aery seemed more sensitive on her right nipple. Probably because it was easier to toy with.

Her slender shoulders, hips, rectal walls spasmed finely — hot, desperate breaths coming from her.

"Aa hii…! N, ku… uu…!!"

Seeing she was nearing her limit, he kept clitoral stimulation to a minimum.

He lightly brushed his fingertip over the foreskin, gently peeling it back. Just that made Aery shake her lower body as if her hips gave out.

Serious juices dripped viscously from her lewd hole. Her whole body broke out in sweat, filling the room with a sweet body odor. If she were thrusting her ass up, one might mistake it for climax.

"Prep's done with this, yeah."

"… Fua… ha, hi… 💕 N, kuu…!"

Resisting the strong clench, he pulled his fingers from her anus with a nyupun.

Aery spasmed her butt with a shudder, dripping thick love juices with a plop.

Yoal glanced at her and picked up the small bottle from the side table.

"This'll be a bit hot."

He called out, but the girl remained face-down, unresponsive.

The contents of the bottle were the same aphrodisiac used on Nyrn. The only difference was that it was mixed with Aery's love juices, optimized for her body. He couldn't use it before because she'd notice the bodily changes, but today it was fine.

This would be the last time, after all.

Yoal gently opened Aery's anus and tilted the bottle's mouth.

The almost jelly-like liquid trickled down her vivid rectal wall.

"… !! A, a, ua, aaa…? Nku, uu… 💕"

The reaction was dramatic.

Aery's body jerked violently, then her breathing rapidly accelerated. Her whole body flushed hotly, dyed in red.

Ha, ha—she repeated aroused yet fragmented breaths. Her butt swayed restlessly, her innocent secret part faintly blooming.

The sticky love juices dripping from her vaginal opening trailed down the tip of the dark, swollen glans.

Setting aside the half-emptied bottle, Yoal grabbed her waist's curve firmly.

"I'm going in now. Relax so you don't get hurt."

"… Ku… 💕"

Biting the pillow, Aery nodded slightly while trembling small.

Yoal thrust his hips forward, pressing the tip firmly against her anus.

A chupu sucking sound arose. Aery's butt quivered fragilely, her rectal walls pressed against him firmly.

He slowly thrust his hips forward. Spreading her flexibly loosened anus, the tip sank into her ass hole.

"A… a, gu…!! U, nn… 💕 Ha… a, ku…!"

The clench was tight but the resistance was faint. Parting her soft anal folds, he made her anus swallow the glans deeply.

Even after inserting the thickest bell end, Aery only roughened her breath. Her knees spasmed jerkily, her chest rising and falling slowly.

"… Any pain?"

"… Hi, kuu… my butt, so full… 💕 A, ku, weird… I'm getting weird… 💕"

Her breathing was frantic, but she didn't complain of pain. Rather, she seemed to feel good as her ass spasmed.

When he rubbed back and forth at her entrance, she gritted her teeth with love juices spilling from her.

Her loosened silver hair scattered messily. The clench inside her rectum became tighter, more passionately sucking on his dick.

"Should I loosen it up a bit?"

Looking down at Aery nods, Yoal slowly rotated his hips.

Twisting as if drilling with his manhood, he expanded her ass hole with gentle back-and-forth.

Even that felt incredibly good. The healthy sphincter clenched his massive rod and her glossy rectal walls massaged his tip. Combined with the depraved feeling unique to anal, the urge to ejaculate suddenly rose within him.

"Fua, a, hi…!! Hon, really, I'm gonna go crazy… 💕 Me, what, like this… 💕"

While slowly thrusting, he lightly tapped her tailbone with his fingertip.

Aery shivered zoku zoku from the sweet tingle, arching her supple back.

"… A, ku hiii… 💕 What, this, my butt… 💕 I'm going crazy… h—, —uh…?"

It was at that moment.

While arching her body, Aery glanced over her shoulder at Yoal.

Her emotionless sand-colored eyes. A faint color tinged them. It was a slight change, but Yoal didn't miss it.

"… Tch."

Was the insertion shock too strong—? It seemed the hypnotic state had been lifted.

"Yo a… a, l, you… what…?"

Aery was still in the depths of confusion. Her eyes darted black and white, completely unable to grasp the situation.

At this point, it couldn't be helped. He planned to lift it after training anyway. A bit early didn't matter much.

Yoal grabbed her hips again and whispered in her ear.

"I'm going all the way in now."

"Eh… a, no, don't, stop—"

Zuryu — zubun, zupu.

He thrust his hips forcefully, parting her narrow rectum to the deepest point. Piercing her intestinal depths zuppu, pressing hip to butt tightly.

Contrary to the wriggling girl's resistance, her fully flushed anal flesh gently enveloped the erection snugly.

In that instant, Aery opened her eyes wide, her whole body shuddering buru buru.

"I… ku, nu… no, nooo… no, aaa… 💕 Coming, something's coming… 💕 Nkuuu～～～… 💕💕"

Zokun, zokun—her slender back prickled with goosebumps.

Thrusting her butt up while clenching her anal ring, Aery savored the anal climax with her whole body. After being meticulously caressed from end to end and teased to the edge of orgasm, she had no choice but to writhe in pleasure without understanding what was happening as she sobbed oh so sweetly.

Yoal then gouged her anus with the movements of his hips. Against the ass hole probing by his viciously thick, veiny, raging hard cock, Aery had no means to resist.

"Like, this… a, nu… remember… aku, hiii… 💕 Hips, stop… please… aaa…! Don't move aaa… 💕"

The room's magic faintly wavered, then quickly lost control and dissipated.

While she made her valiant effort, Yoal coated her anal front wall plentifully with pre-cum.

Connecting their bodies, using bodily fluids as a medium to exercise magic.

Yoal licked his finger and drew a geometric linear pattern centered on Aery's tailbone.

When he pressed his finger precisely on the completed mark, it vanished as if sinking into her body.

The lewd crest was the same type as Nyrn's, modeled after female reproductive organs.

The only difference was one point: it affixed not to her skin, but internally — namely, to her rectal walls.

This way, it wouldn't be exposed to outsiders.

"… Wh, you… what, did you, do…!! A, ku… u, u… 💕"

"You can't put strength in, right? Just lie there. I'll do the rest myself."

He laid the anal-orgasmed, limp Aery down flat on the sheets.

Yoal mounted her, thrusting his hips as if slamming down.

Bam, bam—the mating sounds of flesh slapping flesh echoed out as he filled her ass with his full length.

"Aku… 💕 N, u…!! U, a, fu… n, fuuu… 💕"

Aery bit the pillow tightly as she wailed in ecstasy, her ass spasming all the while.

That ingrained habit hadn't changed even after regaining her senses.
