The overall shape resembled a miniature, limbless, and stripped version of the Teacher Devil, reduced to a bare, flesh-toned form—essentially a lifelike, human-shaped device modeled after her proportions.
Though all of the Teacher Devil's features had been scaled down proportionally, the final product bore an uncanny resemblance to a modern adult toy. The area designed for use—specifically the part corresponding to her lower lips—occupied a significant portion of the device's lower half.
Renji held the toy firmly in one hand, lifting and turning it horizontally. With his other hand, he parted the flesh-toned folds to examine the soft, inner passage.
It really was identical.
"Is this… my doing? Why did the Teacher Devil turn into an ordinary lump of flesh in Kishibe's hands, but in mine, she became… this?"
Renji felt deeply perplexed. But as he looked at the Teacher Devil-branded toy in his grip, and at the miniature, flesh-toned face molded onto its surface, a sudden heat surged through him.
All the energy in his body seemed to rush toward his length, instantly triggering its second-stage evolution.
"Hmm… I suppose I should verify whether it functions as I imagine."
No sooner thought than done. Renji glanced both ways down the corridor, confirmed it was empty, and wasted no time. He pulled down his pants and underwear to his knees. His length sprang free, swaying heavily in the air.
He aimed at the toy's entrance and thrust forward with a powerful Evil Dragon Charge!
The entire toy was just over twenty centimeters long, but Renji's length was already close to thirty. With that single thrust, he pushed all the way to the molded head at the far end, stretching the entire toy into a taut, cylindrical shape. The material strained and began to pull apart at the sides, revealing a pale, gelatinous texture.
"No… this isn't right…! This…! This isn't an ordinary toy! This is… a genuine passage! This feeling…! This is the Teacher Devil's own inner passage!"
After all, Renji had already been inside the Teacher Devil once before. He was acutely sensitive to that specific sensation. The moment he entered, he knew—this was the Teacher Devil's own passage. There was no mistaking it.
The Teacher Devil hadn't simply been transformed into a toy; her entire devil's body was the toy.
Renji pulled about halfway out. The Teacher Devil's chest and the portions above it reverted to their original toy-like appearance.
He took a few steps forward, bracing one hand against the wall for better leverage. His other hand gripped the Teacher Devil toy, now impaled on his length, holding it firmly in place.
Then, drawing a slight breath, he launched another Evil Dragon Charge! His length vanished completely inside, the bestial head once more pressing against the molded head at the far end, stretching the toy taut.
Just as Renji was about to withdraw most of the way to prepare for another thrust, the Teacher Devil toy suddenly stirred.
For some unknown reason, it seemed to awaken. It began to swell rapidly at a visible rate, its limbs extending swiftly.
In less than two seconds, the toy that had just fit in his hand had transformed into a complete humanoid form. At the same time, the Teacher Devil's facial features slowly began to materialize on the flesh-toned surface.
Black hair cascaded down to her pale shoulders. The Teacher Devil's original appearance materialized fully before Renji.
"How did you… change back? And you…"
Though the Teacher Devil had reverted, she was completely unclothed, her black-framed glasses gone. Her full, heavy chest was fully exposed, swaying naturally with the movement.
Renji's hand, which had been gripping the toy, now held the Teacher Devil's slender waist.
And his length, naturally, remained buried deep inside her passage. Not only that—because he had thrust in fully, the bestial head was already lodged within her womb, pressing up against its inner wall.
Renji could see a small, distinct bulge just below her lower abdomen, near where his supporting hand rested on her waist.
Buried deep within the Teacher Devil's womb, he pulsed with occasional, involuntary spasms, causing the walls of her uterus to clench and release in rhythm.
—Splurt!!!—
—Splurt!!!—
—Splurt!!!—
…
Wave after wave of her release gushed forth, her consciousness soaring and plummeting with each crest. Torrents of fluid sprayed from her core.
"Ah… mm… w-wait… just… just a moment… no… please… please…"
The Teacher Devil's current state was a stark contrast to her earlier arrogance. Her face was flushed, but her expression was one of profound distress. The corners of her eyes were red-rimmed, glistening tears welling up and tracing slow paths down her cheeks.
Her voice, when she spoke, was fragmented and faint—the sound of someone pushed beyond exhaustion into a deep, helpless fatigue.
Only then did Renji remember: he had just taken her against the wall, pounding into her relentlessly. Normally, she should still be unconscious.
It was only because she had transformed into a Fiji cup and been "taught a lesson" by him that she had woken up.
"Stop… I'm begging you… I… I'm going mad… don't… don't move anymore… I…"
As she pleaded, she tried to push against Renji with both hands, but it was futile. He was buried deep within her, holding her entire body in a state of utter weakness. The strength in her hands was softer than a whisper.
Renji, however, was displeased.
"Hey, why did you change back? Can you change back? Can you turn back into the Fiji cup?"
The moment the words left his mouth, the Teacher Devil's expression shifted instantly—flustered, uneasy, terrified. Her body trembled slightly.
"No… don't…! Please…! Let me stay like this! At least this way I can… release some of it…! Otherwise, if you keep going without letting me… I'll… I'll die…! Really! I'm still useful to you! I'm still useful! I don't want to…"
"I don't care about any of that. Just change back first!"
As Renji's command took effect, the Teacher Devil's body began to shrink. Within seconds, she had transformed back into the Fiji cup, cradled in Renji's hand.
"Hmm… this is better. After all, it's a Fiji cup. It's been a while since I've used one. Let me finish."
"Squelch, squelch, squelch…"
Renji withdrew most of his length in one swift motion, then drove forward with a brutal, piston-like thrust! He began a rapid, relentless series of deep, punishing drives!
—Thump!—Thump!—Thump!—
Each impact hammered against the Teacher Devil's form at the very apex of the cup, making the top bulge and distort with every strike. One thrust was so violent the cup nearly flew from Renji's grip.
He no longer leaned against the wall. Instead, he gripped the Fiji cup firmly with both hands, arching his hips forward, continuing the savage assault.
Midway through, the intense stimulation forced the Teacher Devil to revert to her human form.
She wept, tears streaming, begging Renji to stop—even for just a minute—asking if she could rest. But Renji didn't listen, didn't agree. He made her change back into the cup.
Finally, from the nearly deformed Fiji cup, a thick rush of seed surged forth.
Renji had expected it to be forced out—the cup was so small, so distorted by his girth, there was no space. But strangely, the seed seemed to vanish after flowing inside.
And on the Fiji cup, at the position corresponding to the Teacher Devil's womb, a small, distinct bulge swelled.
Renji knew the cup's stem was essentially the Teacher Devil's cervical canal. After a moment's thought, he commanded her to revert to human form once more.
In her human form, the Teacher Devil's head lolled forward. She had already lost consciousness.
In this position, her full body weight bore down on him where he was still lodged within her. Without Renji supporting her, her body began to list to the right, rotating slightly before, with a wet pop, he slipped free.
Freed from her, he swung back to stand rigid and glistening in the air—a sticky, triumphant sentinel.
The Teacher Devil collapsed onto the carpet with a soft thump.
It wasn't that he couldn't support her weight—Renji simply chose not to.
And indeed, he saw it: the distinct swelling at her lower abdomen, and from her core, thick, coagulated spurts of his seed now flowing forth in intermittent pulses.
