Flexible Transformation
🕑 Added 2025-10-31 18:00:07 +0000 UTCPatchwork Avery showing off his wild flexibility in a spooky lab. I've had this idea on the back burner for a while and thought I'd 'bring it to life' this year. A half TF'd werewolf helping out with some capacity testing? Couldn't be Ben.
To make up for the lack of posts this month, this series of images also comes with a short story to flesh it all out. Happy Halloween ;3
-----
Avery’s nose brushed up against the test tube. Its bubbling contents, as well as the cracking electricity causing light vibrations to ripple across his fur. “Easy buddy!”
He could feel the maned wolf behind him, hips pressed up against his flank. Avery’s chest flattened against the glass as Ben’s paw gripped the back of his head. Tough claws tugged against his scalp, tilting his head back until their eyes met. Avery could see him fully now. Towering at a height nearly twice the wolf’s normal size. Avery didn’t think Ben could get any taller, but clearly the full moon had other plans.
Ben crouched so his hips became level. The angle practically folded Avery in half, which luckily he could handle in his current state. His own dick twitched to life as he felt the tip of the werewolf’s cock begin to slip through his sheath. The heat from it already causing him to sweat.
Ben let out a low growl. “‘You sure you’re ready?” Another pulse as his cock pushed out farther exposing a thick head. “It’s going to be a tight fit.”
Avery pressed back happily, grinding against the massive cock as it grew harder and harder with each heartbeat. Within seconds it slipped upward between the two, popping out to rest between his cheeks. A moan escaped Avery’s lips as he felt it still swelling between them, it was massive! He couldn’t see, but the weight of it on his back was enough to know. He moved up and down slowly, listening to the wolf react with pleading pants as he teased him. “I’m ready.”
Ben’s grip on him tightened and Avery let out a surprised moan as he suddenly began thrusting. The teasing motion from before quickly turned rougher as the wolf began to prep for his entry. Pre-cum fell from his tip, making the surface slippery and wet. Avery could feel a small knot beginning to form at the base already, rubbing against his taint with each push. The idea of what was to about to come caused him to shudder.
Finally it was time. Ben angled himself upward, powerful legs flexing as he aimed the tip of his cock just under the lynx’s tail. With a loud moan he pressed inside, teeth bared. His large tip caused Avery to gasp as both Ben’s paws gripped him. He pushed in as deep as he could, his knot bumping up against the entrance. Within moments he was thrusting back and forth at a slowly increasing rate. The thick swell of his cock stretching everything open before pushing back inside again. Each thrust shoved deeper and deeper, acclimating itself to the soft curves and grips.
Avery’s claws dug at the glass tube in front of him, moan after moan escaping his lips. He hadn’t felt anything this large before, and the sensations were causing him to shake. “Harder…”
Ben began to pick up pace, his groans increasing. His own balls slapped against Avery’s as he desperately pushed in and out. The crackling of lightning all around them didn’t do much to drown out their moans. Avery could feel each thrust, easing him into his own build-up.
Ben’s knot tapped against his prey with increasing ferocity. It had now swollen to at least twice its size. Each thrust shoved the sensitive bulb between Avery’s soft ass, which caused him to grit his teeth. His tongue lolled out as he let the sensations build, pressing harder and harder.
Avery's eyes rolled upward, his own breathing becoming shallow and quick. He could feel the wolf getting close, as was he. The wolf’s cock was throbbing and pulsing inside him, and he was determined to take it all.
“Harder.” He yelled this time, maybe a bit desperately over the sounds of the machinery in the lab. He felt Ben thrust forward. He felt the knot compressing. It was almost there. He was almost there. Avery’s gasps grew desperate as his own cock bounced below him. “Harder!”
Each slap was teasing his hole, the belly of that massive cock rubbing against his most sensitive parts. It was only a matter of time, it was getting harder and harder to hold back. “Come on big guy…” His eyes looked back at Ben, almost drunk with lust. “Deep as you can!”
At this command Ben pulled back, the swell and tip of his cock lingering just inside. His paws gripped at the stone floor, hips readying for the finale. With one final push his knot popped inside. His head tilted back, eyes snapping shut as he shuddered. “Here it–-comes!” His balls jolted upward, hips pressing forward hard as his mouth hung open with a massive roar. Avery could feel the werewolf begin to unload into him, cock pulsing warmly inside.
“Good ah… b-boy–AH” He was barely able to finish the sentence as his own orgasm struck him. His cock twitched, ropes of cum sputtering against the glass of the tube that he was desperately holding onto for dear life. His ass gripped down on the knot inside him, squeezing against it with each burst.
“G-good…aaahhh” His words caught in his throat as Ben continued to fill him up. Soon Avery’s stomach pressed outward, the knot giving the cum nowhere else to go. The wolf’s howls turn to low moans as his orgasm pressed on. Finally, after what seemed like ages, he finished. His tongue lolled out once more as he moved both paws to Avery’s hips, keeping them both in place as he panted and whined.
Both of Avery’s paws were off the ground at this point, his toes curled in the afterglow. But something felt... different? Ben’s paws felt bigger than before, especially around his waist. In the heat of the moment Avery hadn’t realized, but the werewolf had been growing in size.
He felt a sudden pulse as the knot expanded a bit more, the tip of that thick cock shuddering deeper inside him. ‘Oh shit, is he still transfor--’
The thought was interrupted as Ben caught his breath. He stood up straighter, with the feline fully locked onto him. Avery felt himself rise up the tube with only a brief moment to wrap his arms around it for stability. That’s when he felt it; the thrusts started again. He gave a whimper of pleasure as he was stretched once more. It seemed the night was far from over.

Thanks for pushing through and getting another amazing Halloween image done! That story and the last image especially do a great job of making me very jealous of Avery. I'm all for you doing more stories whenever you get the urge!
