While Ethan was thoroughly enjoying "educating" Kuroka, he was unaware that the true master of this boundless void was drawing near.
Great Red, the True Red Dragon God Emperor.
The powerful being who had driven Ophis, the entity born of "Nothingness," out of the Dimensional Gap. He stood firmly at the pinnacle of the DXD world. Though he typically existed as a colossal red dragon, he was undeniably an intelligent and sentient being.
His constant wandering through the Gap wasn't intentionally meant to stabilize the world's barriers, but his mere presence and movements prevented wars between DXD and neighboring dimensions. After all, to invade another world, one first had to bypass Great Red—a feat nearly impossible and certainly not worth the devastating cost.
...
Ethan flipped the face-down Kuroka over, causing her heavy, creamy breasts to swing before his eyes. He grabbed one in each hand, his fingers digging into the soft meat like claws. The supple flesh deformed effortlessly under his palms, spilling out between his fingers.
Ethan couldn't help but groan at the exquisite sensation. He softened his touch, kneading the large "melons" in circular motions, occasionally pinching the dark, sensitive peaks of her snow-capped peaks.
Muffled whimpers leaked from her gag as Kuroka melted into the pleasure Ethan provided. If her energy weren't so focused on the intrusive string of beads in her rear, she would have been screaming his name in mindless ecstasy.
Her long, shapely legs instinctively wrapped around Ethan's waist, pressing the heat of her core against him. Her slit was drenched; the moist folds and soft mound were slick with a thick, glistening nectar. The sight was a desperate plea for his cock to ram home and ravage her tight, virgin pussy.
However, Ethan merely pressed his thick, throbbing length against her flat belly, enjoying the contrast of her soft breasts while rubbing his shaft against her clitoris. He had made his malice clear: until the beads were expelled from her ass, Little Ethan would not enter her.
Deprived of sight, Kuroka focused entirely on her rear. She panted heavily, her muscles contracting and pushing against the rubber spheres. With a wet squelch, the first bead was forced out of her pink rosebud, glistening with slime.
"Oh... mmmph... ah..."
Ethan reached out and removed her gag, allowing her hot, desperate moans to spill from her lips. Her mouth remained agape, her tongue lolling out in a daze. Even the "mouth" below seemed to be moaning, twitching as it licked the hot skin of his shaft pressed against it.
Under Ethan's amused gaze, Kuroka worked her sphincter, each plop and squish marking the exit of another bead. As her rectum adapted to the stretching, her pace quickened, and waves of shameful pleasure washed over her as the rubber scraped against her sensitive walls.
About a third of the string was out. From Ethan's vantage point, the beautiful Nekomata looked like she was growing a third tail from her ass. Her reason had long since vanished. She didn't even think to use her two actual tails to help; she simply brushed them against Ethan's skin to add to his excitement.
"Ethan... please... Little Ethan... give it to me..." she babbled, her words a garbled mess of lewd desires. To her, this teasing was a far worse punishment than the whipping.
Just as more than half the string hung out, trembling, Ethan smirked. He grabbed the pull-ring and, despite her sudden, desperate struggle, shoved the hard beads all back inside her at once.
"Gah!"
Kuroka arched her neck, letting out a cry like a wounded animal. Her body went into a violent spasm. Ethan reached down to rub her pussy through the deluge of fluids, feeling the beads moving inside her through the thin wall of her vagina. The stimulation caused her to squirt a fresh mist of nectar over his arm.
"So cute, Kuroka," Ethan chuckled. He pinned her legs back against her shoulders, raising her ass and exposing her drenched, flushed sex completely. He began to alternate between digging his fingers into her front and violently pulling the anal beads in and out of her rear.
Kuroka's world became a blur of gasps, spasms, and consecutive orgasms. Her mind broke.
"No... more... Ethan Master... please... my ass... it's turning strange... ahhh! Eeee!"
Her "high" button seemed stuck. She became a quivering mass of meat that only knew how to leak and shake. Ethan finally pulled the beads out for good and removed her blindfold. Her face was a mess of spit and tears, her pride as a powerful Nekomata completely shattered.
Seeing her so vulnerable, Ethan's heart softened. "Kuroka... this wasn't just punishment. It was training. If your climax threshold is this low, you won't even be able to keep up with your sister, Koneko."
"Ko...neko? Shirone?" Kuroka blinked, her golden eyes slowly focusing. "I can't... lose to Shirone..."
A delirious, obsessed smile grew on her face. "Master... I understand. Please... continue the punishment. Kuroka will work hard... mmm!"
Ethan silenced her by putting two fingers in her mouth, which she immediately began to suck and lick with devoted passion.
"That's enough for now. You've repented well," Ethan said, stroking her messy hair. "Now, it's time for your reward."
"Really?! Master, I'm going crazy! Please, shove it all in! Fill me up!"
