Umbreon TF By Singlet (With SS, 900 words)
Added 2025-07-04 15:05:59 +0000 UTC"Heh... this actually feels really good."
The jet-black singlet he'd ordered from an online store clung to his moderately trained body like a second skin.
There had been all sorts of suspicious advertising slogans like, 'Stimulates the body and gives you power,' but just wearing it, he felt a strange vitality welling up from the pit of his stomach, making him think that maybe the ad wasn't such an exaggeration after all.

He began his warm-up on the wrestling mat, the gym still empty, his body gradually growing warmer. Then, a yellow light flickered at the edge of the black singlet.
"Whoa, what the hell is this?"
Yellow patterns were emerging here and there on the singlet's shoulder straps and the edges of the thighs.
That alone would have been nothing special, but a ring-shaped pattern had also appeared around the bulge that housed his genitals, as if to emphasize it.
Frankly, it was embarrassing.

Maybe I should go back and change while no one's here yet...
As he hesitated, continuing his warm-up, the singlet began to move in an even stranger way.
Independently of his movements, the fabric itself began to squirm and caress his skin as if it were alive, applying a pleasant pressure.

"Ngh!"
It felt as though a tongue had grown on the underside of the fabric, licking his flanks, his thighs, and his hardening penis.
Faced with the unexpected stimulation, all he could do was writhe on the mat...
Then, the fabric wedged in his rear stimulated his hole with a slimy slickness, and finally, unable to hold back any longer, he ejaculated.

He let out a small cry and collapsed onto the mat. ...But the rubbing motion on his groin didn't stop.
"What the hell is wrong with this singlet!?"
His legs tangled from the intermittent stimulation, he scrambled to his feet, headed for the locker room, and dove straight into a shower stall.
He hooked his fingers under the shoulder straps and pulled with all his might... only for his skin to stretch with it, unnaturally pliable.
It won't come off... or rather, it's fused with my skin!?

When he let go, it snapped back into shape with a wet thwack, and the stimulation sent a wave of pleasure through him, causing him to ejaculate again.
He could see his own thick fluid, squeezed inside the fabric, slowly seeping along his skin and leaking from the edges... but its texture had transformed into a glossy, black mucus.

Ignoring his screams, the mucus began to fuse with the singlet's fibers, expanding its area. The singlet—now half-transformed into a slimy substance—slimily crept over his shoulders, his arms, and his thighs.
His screams of confusion soon turned into cries mixed with pleasure. The mucus enveloping his skin侵aded inward, violating his cells and inflicting a bizarre pleasure upon him.
This prompted him to ejaculate further, plunging him into a loop of violating and remodeling his own body with the black mucus he produced, creating even more pleasure.

The penis that should have been under the fabric was remodeling itself, erecting beyond its limits, and with each ejaculation, it seemed to increase in thickness, length, and the volume of mucus it produced.
Even after ejaculating dozens of times, far from being exhausted, he felt even more energy welling up from his penis, which was then distributed throughout his body with each release.

As most of his body became enveloped in the mucus, his entire form was being reconstructed by the singlet's fibers... by bio-rubber.
His muscle fibers were rewoven to be stronger and more flexible, his muscles expanding with the creaking sound of rubbing rubber. His arms thickened like logs, and his pectoral muscles swelled like mountains.

And then, as he gurgled on the mucus overflowing in his throat, the final moment arrived.
An impulse of unprecedented intensity shot up his spine, and a tremendous torrent of mucus erupted not from his penis, but from the base of his backside.
It swirled into a spiral, forming a thick, supple tail.
Simultaneously, the bulge in his groin, which had been encased, seemed to pull away and become independent. From a penis of inhuman size, adorned with a yellow ring, black mucus sprayed outwards for the first time, signaling the end of the transformation.

For a while, he lay on the cold shower room floor, his body trembling as he panted, but eventually, he stood up and cautiously looked in the mirror.
The figure reflected there was no longer human.
His entire body was covered in—no, he could feel that it had become—the same glossy black material as the singlet.
His honed muscles were powerfully beast-like, and from his rear, a magnificent tail with yellow ring patterns swayed, feeling the air currents.
And sitting atop the thick, powerful torso was an animalistic head, cute in a way that didn't suit the body... a black head of a beast he'd seen somewhere before. Its ears stood pricked up, and on its forehead and both ears, yellow ring-like patterns glowed faintly. Its crimson, shining eyes stared back at his face.

"Th... This is me...?"
The confused words escaped his mouth. But at the same time, he couldn't stop the excitement that welled up at the sight of his own reflection, a mass of gleaming black muscle.
I want to wrestle. I want to grapple with someone and test this surging power.

But first.
"I've gotta do something about this..."
He looked down at his huge, throbbing penis, aroused by his own body, and laughed, exasperated but somehow amused.

3rd pic, This is a study of things like spandex or thick latex-like fabrics that I sometimes see in AI art. I tried using that for Umbreon this time.
I want to aim for weekly Friday updates in July (although I'm already cutting it close with this upload time... ^^;).
I hope to keep uploading something!!
