Chapter 2 - A Nun's Corruption

Asia Argento, an excommunicated nun turned devil, made her way up the stairs to her clubroom. 

"I wonder why Buchou called for me...?" She murmured to herself as she arrived at the door to the room. 

Opening the door after she knocked, the blonde paused as a strange smell hit her nose, teasing her entire body pleasantly. Filing it as something she didn't recognize, she proceeded to enter. Instead of seeing a redhead seated behind the desk with her second-in-charge standing to the side as usual, Asia was met with the sight of both girls looking extremely filthy, with torn and smeared clothing, slumped on the couch.

"Buchou! Akeno-san!" Asia cried out in shock at her fellow devils' condition. "Wh-what happened to the both of you!?"

"A...Asia..." Rias said weakly. "He...help Akeno first..."

"Please hang in there! I will heal you right now!" 

Green light appeared around her hands as she engaged her Twilight Healing, and under its glow, the scrapes on Akeno's body began to heal. But that was not all there was to heal; the state of Akeno's clothes left her lower parts exposed, and it was evident to anyone who looked at the white fluid leaking out from her gaping vagina that the black-haired girl had just been sexually violated.

"How cruel... what did this?" Asia questioned.

Neither girl answered, but an expression that looked like relief passed over Akeno's face as the wear on her body faded, her wrecked cunt regaining its tightness. Out of the blonde's line of sight, Rias bit her lower lip, shivering as she recalled the memory of the experience. Her womb clenched, pushing out a thick dollop of cum from inside her, and causing the musky smell in the room to grow even stronger.

Her attention on healing Akeno, Asia didn't notice the change in the clubroom's atmosphere, but her body responded all the same. She started to breathe faster, even as her nipples hardened and her pussy became wet underneath her clothes. 

Not realizing how flushed she had become, the nun turned to heal the redhead. Unlike with her previous patient, the healing process this time took longer; her unconscious arousal made her more easily distracted by the sight of all the semen on Rias's body.

"Thank you, Asia." Rias sighed as she felt her body recover.

"Y-you're welcome, Buchou..." Asia replied flusteredly. "But... what happened?"

She didn't expect the reply to come from Akeno, who suddenly leaned onto her back, bringing a thick smell of semen with her.

"Something... really good... Asia-chan." The priestess cooed.

"Wha... Ake...no...san..." Asia found her body suddenly not responding to her will, and everything started to go dark for her.

The last thing she saw before darkness claimed her was the pleased smile of her King, Rias Gremory.

Seeing Asia slump unconscious into Akeno's waiting hands, Rias smirked. "Well done, Akeno."

"You're welcome. Let's move her over to the teleportation circle."

Rias nodded and started to assist her childhood friend. "I can't wait to experience horse cock again, now that my pussy's regained its tightness." 

"Me too... just thinking about it makes me want it even more." Akeno shivered, almost dropping Asia.

"Asia's sure to enjoy it as well..." 

With that, the magic circle activated, and three girls vanished in a cloud of red sparkles.
-----------
 “Ahhh! Oh yes! Masterrrr...!” 

Asia's eyes flickered open as she came to, roused by the sound in her ears. “H-huh...? What... happened...?”

“Harder! Harder! Fuck me harderrrr!” 

“Who is it... that's talking...?” The nun wondered, lifting up her head. “Eh?”

With a start, Asia realized that she was tied up and completely naked; her legs were bound to rods planted in the ground, and from the cool feeling around her butt, the chair she was sitting on had part of its seat missing. But what caught her attention more was the spectacle in front of her; Akeno was on her hands and knees with her hips raised high, and a huge stallion was thrusting its penis right into her.

“A-Akeno...san?” The blonde whispered in shock.

“Yes! Oh yes!” The black-haired girl wasn't even listening, her body rocking with every thrust. “You're wrecking my cunt, Master! And it feels so goooood!”

“Are you awake, Asia?” The sound of another familiar voice made the nun turn her head.

“Buchou!” The innocent girl's eyes widened as she took in the appearance of the redhead she owed her life to. “Wh-why are you...?”

Rias stood next to the chair, completely naked and splattered with cum. Compared to her normal nude figure, the blissful look she had on her face combined with the semen coating on her skin now made her look like an utter slut. Even more, Rias looked like she knew that, and didn't mind it at all. Rather, she enjoyed it.

“Why am I naked?” Rias laughed lightly. “Isn't that obvious? It's so King can fuck me whenever he wants.”

As though summoned, another huge stallion came up from behind Rias, putting its head over her shoulder. Asia flinched back from its red gaze, or at least tried to; all it did was remind her of her restricted condition. Rias rubbed her cheek against the side of its face tenderly, letting out a moan of pleasure before catching herself.

“Oh yes, I forgot to thank you, Asia.” She spoke to the blonde.

“Thank me?” Asia questioned, confused.

“That's right. After King fucked me for hours yesterday, my pussy became really loose, you know.” Rias shamelessly confessed, “But thanks to your Twilight Healing, it's become tight again, and it felt so much better when he fucked me just now.”

“Eh? Bu...buchou?” Asia couldn't believe her own ears.

Rias caressed King's head. “The feeling of having a thick horse cock forcing your cunt wide open... it's so incredible, don't you know? Just look at Akeno.”

Asia couldn't help looking, and what she saw terrified and aroused her; The girl known as the Thunder Priestess, with her sadistic side, looked so happy receiving the stiff length of meat belonging to the horse mounting her. The girl had the widest smile on her lips, and her eyes were rolled back in bliss, even as she howled her pleasure out for all to hear.

“AAAHHHH! MORE! FUCK ME MOOOORE!”

“Something that big...” Asia whispered to herself, unable to pull her gaze away.

“That's not all, Asia,” Rias added, “When the horse cums, when his balls pump thick, hot cum into your womb, so much that it makes your belly swell and even overflows back out your pussy...” She shivered as the memory evoked an orgasm in her body. “I've never came so hard, or so much, before...”

At that moment, the stallion fucking Akeno let out a mighty snort, and began to ejaculate. 

“Oh! Oh, oh, oh, oooohhhhh!” The girl moaned loudly as hot horse cum gushed into her womb, causing her belly to swell up. “Y-yes... fill me... p-pump me full... with your hot cum!”

In a matter of minutes, her body went from its slender shape, to looking like she was on the verge of giving birth. Asia could even see some white fluid drip out onto the floor from where Akeno and the horse were connected. Throughout the entire process, Akeno kept thanking the horse over and over for giving her its semen, occasionally stuttering as orgasms wracked her body. Finally, after what felt like an eternity to Asia, the stallion backed away, pulling a stunning length of cockflesh out from Akeno's abused cunt, causing a small fountain of thick semen to gush out.

“Isn't it amazing?” Rias said breathlessly. “It makes me want to get fucked again...”

“Akeno-san...” Asia whimpered.

“Ah, uh, oh... uhhh...” Akeno slumped down where she lay, her hips still twitching occasionally. 

“What's this, Asia?” Rias suddenly said, leaning down over the blonde's belly. “Looks like watching Akeno has gotten you aroused...”

Before Asia even realized what was happening, something brushed across her private spot, setting off what felt like a lightning shock throughout her body.

“Ahn!” She cried out, without meaning to.

“Feels good, doesn't it, Asia?” Rias smiled down at her, with one hand out in front of her eyes. “Just look how wet you are...”

“I-I'm not!” Asia denied, not wanting to accept what she was witnessing as reality.

“Just relax... what you are going to experience, will be much, much better...” The redhead cooed.

Asia tried to say something, but found her mouth covered by Rias's, and a tongue pushing something sweetly bitter into hers. As she gulped it down reflexively, Asia felt a warmth spread throughout her body, but concentrating between her legs. When Rias pulled back, she tried to ask about it, only to have her mouth sealed again, this time by a rubber gag. The horse that was with Rias moved around to stand in front of her, next to the one that had been rutting with Akeno. Their combined gaze bored into Asia as if to let her know that her fate was sealed, and she shut her eyes rather than face them.

“Come on, Akeno, get up.” Rias's voice chided. 

“Uhhhh...”

“Really... you're so hopeless...”

Asia did her best to pray, but for some reason, she found it hard to focus on anything else except the tingling between her legs, which had been growing stronger ever since Rias had touched her there.

“Open your eyes, Asia.” 

The blonde did as ordered. Akeno had managed to get to her feet, and was currently half-crouched over a bucket. The black-haired girl alternated between pressing down on her swollen belly and rubbing her nether lips, forcing out the viscous white cum inside her womb. Akeno herself was enjoying the act, letting out loud gasps and moans as she climaxed over and over, almost in time to the particularly thick clumps splashing into the bucket.

Rias was standing off to the side, with a large-sized syringe in both hands. Its plunger had already been pulled back, and inside its clear chamber was a milky-white liquid that Asia could easily guess the source of.

“You'll love this, Asia.” Rias assured her, “Getting it directly from the source is a bit much for you at the moment, but this will help prepare you for that.”

Asia tried to scream as the redhead approached, or at least spit out the gag, but it was futile. With no other option, she clenched her eyes closed, not wanting to see it happen.

“Here it comes~” 

With that, Rias pushed the tip of the syringe into her Bishop's cute rosebud, and began to depress the plunger, sending a torrent of demonic horse semen through Asia's anus. The alien sensation made Asia jerk around in her bonds furiously, but there was no escaping the corruption. 

The effect was almost instantaneous; Asia's gagged screams became aroused groans, her nipples leapt to full erections, and the trickle from her pussy lips became a gusher as the nun climaxed hard, splattering the syringe with her love juices. Rias paused in her task to collect some of it on her hand, and licked it off her fingers.

“Mmm~ You taste good, Asia,” Rias purred, “I can't wait to see how adding horse cum to that will change the flavor...”

Asia barely heard any of it; her mind was swimming in bliss, as the demonic energy in the cum remade her body to accept- no, to lust for horse cock. As the syringe continued to pump even more of it into her, Asia's transformation took place faster. Her breasts increased by one cup size and started to leak milk from the nipples, while her pussy's lips opened up like a flower's petals with a jutting clitoris, putting out its own musky scent. 

“There's still more to go, Asia.” The syringe popped out from her ass, and Asia instinctively clenched it to prevent any of the whitish goodness from leaking out. “Good girl...”

The nun was barely aware of Rias refilling the syringe from the bucket Akeno was holding up for her, or how the two girls approached her once it was full. The ecstasy she had been feeling earlier was starting to fade, and she was desperate to experience it even more. Asia lifted her hips eagerly, presenting her clenched asshole for the syringe.

“Let me do it this time, Rias.” Akeno sounded tired, but eager.

“Be my guest.” Rias moved around to the side. “I tasted her cunt juice earlier, now let's see how her milk tastes.”

Akeno knelt down between Asia's legs, and brought the tip of the syringe to the orifice, which relaxed to let it in. However, instead of pumping it in right away, she moved the syringe around in a circle, teasing the nun's rosebud and making the blonde trash and groan desperately. The horse named Master might have awoken the masochist in her, but Akeno had not lost her sadist side in the least. Bringing her face closer to Asia's wet cunt, she blew air over the sensitive petals, eliciting an even bigger reaction from the girl.

“You want it, don't you? Asia-chan~” Akeno teased, keeping the syringe in place with one hand while the other caressed Asia's clit. “You want all this thick, hot horse cum inside you, right?”

“Mmmmph!” Asia struggled.

“Hey, Akeno! I can't drink properly like this!” Rias scolded, her intention of suckling from Asia's breast having been disrupted by the thrashing.

“Sorry, Rias.” Akeno apologized, not sounding sincere.

“Just do it already.”

Instead of answering, Akeno jammed her hand against the plunger, squirting a huge load up Asia's ass. It caused the blonde nun to jerk, as well as her breasts to suddenly shoot out milk, right into Rias's face. As more of it began to flow into Asia's already full hole, her belly started to bulge visibly, and she started to experience a long, drawn-out orgasm, her pussy squirting nectar out into Akeno's ready mouth.

“H-hey!” Rias complained, but before she could say anything further, a snort from King interrupted her. “A-already? O-of course!”
The sexy redhead got on all fours and raised her ass. The stallion moved into place over her, and sheathed his gigantic shaft into her waiting cunt, causing her to cry out in ecstasy. Unlike his counterpart who wanted his slut to start off by servicing him, King preferred to take the main role in the fucking. His cock punched straight into her womb, jerked back out, and slammed back in, over and over. 

“AAAAAHHHH! GOOD! SO GOOD!” Rias screamed, one hand groping her own tit. “FUCK MY WOOOOMB!”

The other two girls were engrossed in their own world; Asia's corruption was nearly complete, and Akeno was doing her best to help it along. The Thunder Priestess rubbed the sopping cunt in front of her face with both hands, flicking the erect clit and tugging on the floppy pink petals, while she prodded the tightened rosebud with her tongue, trying to get it to release its treasure.

Asia felt her control slipping; the innocent and kind girl she originally was was nearly gone, and the new self that was taking hold in her was filling her mind with all sorts of interesting and erotic ideas. Like tasting a sweaty horse cock, sucking on it, letting it fuck her throat, taking it in her virgin cunt, accepting it in her defiled ass, letting its delicious, slimy jizz soak into her skin...

She came, and released the hold over her anus, sending a torrent of glowing white cum shooting out over Akeno and into the black-haired girl's open mouth. 

“MMMMMMMNNNNNHHHH!” Asia's eyes rolled back in her head as she jerked in her bonds.

“Aaahn~” Akeno reveled in the white shower, massaging the sticky juice into her skin and gulping down whatever went into her mouth. “So tastyyyyy...”

King's balls tightened, and liters of semen flowed down his penis and out into Rias's battered womb. Like Asia's had earlier, the redhead's belly started to swell, but hers grew to resemble one belonging to a woman in her last month of pregnancy. 

“EEEEYAAAAAAHHHH!” A third voice joined the chorus of orgasmic cries in the barn.

In the midst of the shared climax, Akeno was discovering something special about her new method of taking a cum shower; her scrapes were healing as her skin absorbed the glowing fluid, and she could feel her pussy tightening once more. Somehow, the power of Twilight Healing had infused the cum inside Asia, and showering it in released its effect on her.
However, before she could ponder on it, the other stallion present nudged her imperiously. He was tired of waiting too, and he wanted in on the action.

“I'm sorry for making you wait, Master,” Akeno groveled, “I will prepare this slut for you right away!”

With quick bursts of magic, she removed the ropes restraining the nearly comatose Asia. But before she could do any more, the stallion shoved her away and stepped into place over the nun, putting his cock in position over her virgin pussy. Master lowered his head down over Asia's face, and a purplish-red tongue slithered out from his mouth.

“Nnnn...” Asia mumbled as the demonic-looking appendage wormed into the corner of her mouth and extracted the gag. “Uhhhh... Mmmph!”

Her eyes widened momentarily as she became aware of the oral invasion, but surprise was soon replaced by arousal, and Asia sucked eagerly on the prehensile tongue. The cum had altered her body to make her mouth more sensitive, and the grunts and slurps she made let all present know just how much she enjoyed getting tongue-fucked.

“Mmm... smooch, so hot, stinky, sweaty... so much cum, packed inside... Mmmm~” 

Akeno's voice formed a duet with Asia's, as the Thunder Priestess kissed and licked at Master's swollen scrotum, preparing its load for the delivery. Under her attention, the bulging orbs grew even bigger, as did the long pillar of flesh it was linked to. Still, it remained outside of Asia's body.

After several minutes, Master raised his head, pulling his tongue out of reach of Asia's face. She made a needy mewling sound, but instead of answering her plea, the stallion shifted forward and poked the dripping tip of his cock against her pussy.

“So big...” Asia breathed.

“That's right...” Akeno paused in her licking to speak, “This cock took my virginity, and I have never regretted that. You won't either... you want to feel it inside you, don't you?”

With her eyes locked onto the flared head that hovered between her legs, the blonde nodded. A trickle of drool ran from the corner of her mouth as she continued to stare.

“Then beg him for it... beg Master to take your virginity!” Akeno finished, one hand already rubbing away between her legs.

There was no thought spared for the brown-haired boy that she was so fond of before, as Asia reached down and pulled her nether lips as wide apart as she could manage.

“Please... take my virginity...!” She gasped out.

Master snorted, and thrust his hips forward. The gigantic cock pressed against the virgin nun's opening, and easily slid in despite its girth. Her reaction was incredible to witness; Asia screamed out loud in joy as her pussy began squirting her horny jizz over the remaining length of Master's cock, feeling it stretching her out beyond what normal women could bear.

“De-deeper! Go deepeeeerrrr!” Asia begged, feeling the head scraping against the walls of her cunt, approaching her womb. 

“Yes! Fuck her hard, Master! Rape her womb! Mark it with your cum!” Akeno hissed, masturbating furiously beneath the horse's scrotum.

The King and Bishop's screams of ecstasy echoed around the barn as the horses' cocks pounded their wombs like jackhammers, sending them to climax over and over. Underneath it, Akeno's joyful laughter sounded, for she looked upon the scene before her, and knew that all was as it should be.

“M-Master! Cum in me!” Asia squealed, watching the bulge in her belly move up and down. “Fill me with your cum!”

“Oh yes! King! Use this cocksleeve!” Rias groaned, feeling her entire pussy from opening to the back of her womb clamp down on the pillar inside her. “Unleash all your lust out inside me!”

“That's right! Teach us our place!” Akeno moaned, using the discarded syringe as a dildo and ramming it inside her own cunt. “We are cum sluts who can't live without your strong, hot semen!”

As one, all of them came together, but above the voices of Rias and Akeno, Asia's scream had a note of farewell to it, as her fate as a slave to horse cock was sealed. 

Some time later, the pair of Asia and Rias could be found squatting over separate buckets, busy licking at their respective partners' cocks while Akeno massaged their bellies to force out the thick cum inside their wombs.

“You know, I've thought of a good idea...” Akeno confided.

“Mmm... what is it... Slurp- Akeno?” Rias asked in between licks.
--------------Much later, Hyoudo Issei was walking towards the Occult Club Building when he noticed a new addition on the side. Curious about this sudden development, he decided to investigate. To his own surprise, he found the four girls of the club there, along with two huge-sized horses.

“Buchou, what's this?” He asked Rias.

“These two are for the new equestrian club, but the school currently lacks enough space to hold them, so I offered to put them up here for now.” The redhead held up a brush. “Besides, it might be interesting to take care of them for a bit.”

Issei started fantasizing about being brushed down by a nearly-naked Rias, before catching himself.

“We're almost done here, Issei-kun.” Akeno said from the other side of the second horse. “Why don't you wait for us in the club room?”

“Sure! I'll be waiting then!” So saying, the boy ran out of the stable.

“Really, that Issei...” Rias sighed, before turning to look at the fourth member of their group.

“How is it, Koneko-chan...?” Asia asked timidly.

Toujou Koneko sniffed the cup of milk curiously, a blush spreading across her cheeks. Failing to detect anything wrong, she brought it to her lips and took a gulp. Her eyebrows shot up, and she immediately began to swig the rest down. Asia, watching with a strange glint in her eyes, shivered as a wave of pleasure ran through her body.

“Delicious.” Koneko announced.

“That's great!” Asia smiled brightly. “Then I'll prepare some more for you right away!”

Beneath her skirt, a series of straps held a pair of dildos in place within both of her holes, but they failed to prevent a few drops of white jizz from trickling down her thighs. Hidden behind the horse's body, Akeno massaged her breasts through her cum-soaked  top, while Rias pressed down on the front of her skirt, enjoying the feeling of horse cum being forced out through her loose cunt.
