The Academy's Exclusive Whore's Professional Ethics (4)
When the artificial lifeform known as a slime was first installed deep inside Gyeoul's womb, one suggestion had been made. What if they added a function that let the slime secrete its own lubricant in place of her natural juices? However, that proposal was rejected—not only for practical reasons like whether it was even possible, but for matters of taste as well. Especially vocal in her opposition was Kazuha, who had always possessed a strong anal fetish and had already claimed Gyeoul's anal virginity. She had declared with fierce conviction:
A few others had nodded along, murmuring things like, “Is that so?” and “I can kind of see it…” In the end, the slime was never given that function. And Kazuha did not regret that decision in the slightest.
She coated her entire cock with the slick, sticky fluid known in modern Korea as love gel—the kind used for sex. Then she applied it thoroughly around Gyeoul's anus and the surrounding area. Finally, she squeezed a generous amount directly into the gaping hole, completing the transformation of her rear into a proper back pussy.
“Haa♡”
Kazuha truly, unbearably loved this moment. Pouring all that affection into the act, she pressed the head of her cock against Gyeoul's back entrance. The sphincter, already loosened and glistening, made no attempt to resist. The instant her cock touched it, the hole tightened in surprise like a virgin feeling a man’s hand for the first time, but it quickly melted open again with a wet, inviting ♡.
It was as if everyone had thought her a pure maiden, only to discover she wore nothing beneath her outer clothes like a total slut. And into that hot, welcoming back passage, Kazuha slowly pushed her thick oni cock.
“Haa…♡”
The oni’s girthy shaft invaded Gyeoul’s body. Kazuha loved—absolutely loved—the sensation of stretching open an unused anus for the first time, of forcing the sphincter wide around her cock. In truth, she loved everything about Gyeoul’s asshole and never held back. But slamming straight in without letting the hole adjust would have been wrong. So she pushed in gradually, letting it adapt.
“Huu…”
Kazuha’s face went slack with pleasure as she savored the feeling, looking almost stupidly blissful. There really was something special about the first time a cock was enveloped by a pussy. It was like slipping into a hot spring for the very first time—the tingling rush through your whole body. After that, the water still felt good, but that initial, electrifying thrill never quite returned.
Of course, while Kazuha was lost in that sensation, Alejandra’s massive, brutal cockhead was thoroughly enjoying Gyeoul’s throat pussy. Thick, foamy saliva drooled down in heavy strings, and tears welled up from the physical stimulation. Yet Gyeoul showed no sign of discomfort. She didn’t even feel any real distress. This body, a lewd gift from a succubus, would go into heat at the mere sight of a cock. Having her throat used like a pussy filled Gyeoul with deep satisfaction and a profound sense of purpose.
Still, the reduced airflow made her head grow hazy. And it was in that dreamy state that Kazuha’s cock pushed into her asshole.
“!? ♡♡!!!”
The shaft forced its way in, creaking and stretching her back pussy walls. In truth, it wasn’t easy for a cock to be fully “enveloped” by the rectum during anal sex. The space inside the rectum was naturally wider than the average cock’s girth. That was why so many anal sex reviews complained that “only the entrance tightens; the inside doesn’t cling at all.”
But when the cock was thick enough, that problem disappeared. The average diameter of the rectum—the wider space beyond the anal sphincter—was around five centimeters. And every futanari at the academy possessed a massive cock thicker than that. As Kazuha’s shaft filled Gyeoul’s rectum completely, the girl felt an overwhelming wave of pleasure mixed with a violent urge to defecate.
What’s more, Kazuha’s cock not only scraped all the best spots inside her ass but also stimulated her pussy from behind. At first, though, the pleasure wasn’t that intense. The area near the vaginal entrance with the strongest sensitivity was the G-spot, which lay on the front wall. But the moment Kazuha’s cock pressed firmly against the back of her womb, an enormous surge of ecstasy slammed into Gyeoul all at once.
“♡♡!!!!”
Her legs snapped shut instantly, and her hips jerked upward in reflex. It looked like she was performing some bizarre gymnastic pose. Immediately after, a powerful gush of girl-cum sprayed out—pshuuuuuuuut!!—soaking the sheets and splashing hard enough to splatter against Kazuha’s thighs. A little even reached Alejandra, but since Gyeoul’s throat juices were already dripping everywhere, she barely noticed.
“♡♡”
It was Gyeoul’s first anal orgasm of the day. At the peak of climax, the muscles around her pelvis contracted violently, making both her pussy and asshole twitch and squeeze—♡ twitch twitch ♡ squeeze squeeze ♡. Her empty front pussy clenched pitifully on its own, weeping thick, cloudy nectar like tears. But her stuffed, stretched asshole clamped down hard on Kazuha’s cock, gripping it greedily.
“Haa, ah♡”
The rhythmic sensation of her hole seizing the cock, releasing it, then seizing it again. Because Gyeoul came so easily, anyone who fucked her would experience this moment many times. And in those instants, the male penetrating her would feel as if he weren’t the one doing the fucking—he was being lured into it, almost like he was the one being reverse-raped.
It didn’t feel like her pussy was coquettishly begging for his cock. It felt like the pussy was voraciously claiming it. Like it was strangling his shaft, putting a collar on it. A terrifying sense that the woman he was supposed to be dominating was stealing control—perhaps even something far more important. An ordinary man born with a cock, someone who already knew how completely lust could rule a man’s brain, would probably have felt that fear even more strongly.
But the futanari who had gained their cocks later in life understood the terror of uncontrollable desire, yet they didn’t yet realize that such desire could force a man to his knees before another person. They knew the fear of being unable to restrain their own lust, but not the fear of being brought to heel because of it. They simply hadn’t imagined it yet.
Besides, the feeling never lasted long. If the male froze in shock, her hole would immediately caress him with gentle, apologetic squeezes—squeeze squeeze—as if saying, “I’m sorry, did I scare you?” And if he refused to submit and kept thrusting, it would instantly surrender with a “You’re the best♡” and turn back into a sweetly fawning pussy.
It was the same now.
“Ah, haa…♡”
The moment Kazuha moaned at the sensation of her cock being collared, Gyeoul’s back pussy shifted from its tight, seizing grip to a soft, kneading massage. As if apologizing. As if saying, “Are you mad? Please punish this naughty pussy♡”
“Ha, huu…♡”
Kazuha smiled without realizing it and drove her cock deeper. She scraped the back of the womb, and before long her massive shaft reached the “end” of the rectum. About fifteen to twenty centimeters inside from the anus lay the junction between the rectum and the sigmoid colon—another sphincter. Kazuha stopped there for now, refusing to force her way any deeper.
Her cock still had some length left outside, but from this point, simply pushing wouldn’t work. The entire rectum needed to grow accustomed to the pressure, and that second sphincter had to relax. Still, Gyeoul’s body had been created through a succubus’s ritual, so it was exceptionally resilient. It wouldn’t break easily. No matter how hard she was fucked, she wouldn’t bruise. No matter how impatiently something was shoved inside her, her flesh wouldn’t tear and her muscles wouldn’t suffer sudden strain.
So even if Kazuha forced her cock past Gyeoul’s rectum right now, the girl would only feel momentary pain and suffer no lasting harm. Or so one might think.
But that was wrong.
Kazuha had no desire to hurt Gyeoul even a little. As someone who worshipped anal pleasure, doing so would be an unforgivable sin. One could call it a violation of aesthetics. It sounded needlessly pretentious, but no better description came to mind.
Besides, the length she had already inserted was more than enough for proper pistoning. Roughly two-thirds of her massive cock was already buried inside.
“Haa…♡”
Kazuha slowly pulled her cock back. When the glans scraped the back of the womb again, Gyeoul came instantly, squirting another powerful jet of girl-cum. She drew back until the head caught on the anal sphincter, then pushed in again just as slowly. Once more, she knocked gently against the entrance to the sigmoid colon with her cock.
Hurry and open up♡ My cock needs to get in, so open up for me♡
