"That's good, Blitz! Push harder!" The beefy Doberman asserted to the otter busy bouncing on his cock. The hot pleasure of the otter's body was at first exquisite. He always enjoyed the smaller males and feeling them getting bigger with muscles as he worked with them was delicious. But over the last few days the Doberman had begun to lose interest.

It wasn't that the otter wasn't attractive, he was a getting to be a rather rugged male. But, the canine had once again began to lust for a tiny twink to bulk up while he fucked them. But he would have to get rid of the otter first...and he had the best way to do it. While he was longing back, with Blitz riding his cock and performing on the rowing machine, he reached into his gym bag. From the gym bag he pulled out a needle and thread.

"Keep pushing, Blitz! You can do it!" He tossed another generic encouragement and stifled a moan as the tight ass clenched on him again. Each time he rowed the weights back and forth the otter rode his cock like a pro. The Doberman who owned the gym, also felt as if he could have any man that entered his gym, so he was used to having his cake and eating it too. Once the magic thread was secured through the eye of the needle - which took a good few moments - The Doberman pierced the otter's back.

There was no pain and indeed the otter continued the workout as if nothing had happened. The hot sweaty sex continued as the dog stitched a heart painlessly into the otter's back. When thread met threat again and closed the heart, the shape shimmered with a pale blue light.

"Alright that's enough."

Blitz stopped rowing, but kept bouncing on the sloppy boner a few more times. He finally pulled himself up and off the cock and stretched his legs, feeling a warm itch on his back. He thought nothing of it and instead went to the next machine, which in this case was a Rear Delt Machine. Blitz sat down on the bench and began his workout, he was in such a frenzy he didn't even miss the doberman's cock.

"Great... feel the... burn." The large canine male, was still sweat as he watched the black fur shift and shimmer. The fur turned softer, which more stitching growing down the length of his spine. Every time Blitz moved his arms forward it stretched his back and allowed a deeper view of the stitches crawling down his back, spreading the new synthetic fur outward from it. The Doberman felt his arousal flare up again and he crammed himself on the bench with Blitz to once again fill the otter with wet dog cock.

Blitz moaned loudly and only faltered in his routine a bit before he recovered, "Wow,... you're really horny today!"

Still the otter wasn't aware of what was happening to him. That only made the canine fuck his ass harder. The stitches had also been going up the spine and once they got to the otter's neck, their direction changes to a circle looping around the base of the neck. More stitches grew from the main line and followed the line of the black furred arms, encircling his wrists and each knuckle of his fingers.

"Oh fuck... keep going." At this point, even the Doberman wasn't sure if he was talking to the magic stitches, his throbbing cock slowly working towards his climax, or the unaware otter pumping his transforming muscles. But it didn't matter, none of it would stop - he didn't want it to. Each pump of his hips delivered his throbbing cock into a body that was becoming less flesh and more fluff. The warmth tight tunnel he was fucking was slowly becoming a silky tunnel soaked in his precum.

"So good." The Doberman had his tongue hanging out as he grabbed the otter's body and it yielded under his strength far more than it should have. He was delighted when he realized that it was like he was grabbing a pillow. The otter's arms were beginning the process now, making it harder to move the weights. "Stop here."

The Doberman didn't even wait for the otter to register what he had said before he grabbed the transforming mustelid right off the bench. With a series of quick but awkward steps to the weight lifting bench, both men sat on the new bench. But Blitz moaned loudly as he felt himself getting turned around on that hard wet cock, but he was going to enjoy slapping this dog in the face with his - butt?

"What the hell?!" Blitz was looking right at it but he still couldn't believe it! His lower body was facing the wrong way with his belly having been twisted like a stuffed animal so that his upper body was facing the opposite direction. He watched the dog gasp at the sight of his twisted body but all he did was pick up his leg and turn his lower body the same direction. He wasn't helping him? "Did you do this to me?"

"Yes." The dog was calm now, his panic at being discovered melted away no that the transformation was this far along. There was nothing the otter could do to change his fate now. "Lay down."

In a quick movement, the Doberman grabbed the heavy bar and dropped it, forcing the otter to catch it in his hands. His arms were still shifting, but had enough muscle left in them to save his life. He pushed the bar up, but the dog grabbed himself and started fucking the soft otter, feeling the hard body still turning to a soft fluffy around him. The feet that once felt heavy, he lifted with ease now and lightly nibbled on the otter toes. Blitz shuddered and trembled, trying to stay focused on holding the bar up.

Every passing second brought more fear into the otter's mind as the bar fell inches close at a time. The weight was slowly crushing his arms that were filling with plush. The confused otter was extremely thankful that there was no pain at all in any of this. Blitz finally saw the stitches on his hands and fingers and watched his natural fur changing to synthetic fur. It didn't look any different, but it felt different to his brain. The Doberman quickly caught the bar and held the black and white furred hands to it as he watched the otter's face change.

The magic thread crawled up over the otter's cheeks and stitched into his lips, pulling his lips closed and stitching a perpetual smile on his face. The Doberman was pumping so hard, the silk around his cock not clenching on him, but it was still stimulating him intensely. The otter's body was nearly motionless as he slammed into it, watching the stitched make their way to the eyes still unchanged.

There was nothing left of Blitz the otter now except for those eyes and the needle simply touched each eye. The wet soft orbs, shifted and change into a hard and shiny plastic, shining with bright red color that seemed to twinkle. It would almost be a shake to destroy this cute little toy, but the Doberman had no intention of letting his lusts go unsatisfied. He dropped the bar and watched it hit the plush body.

The weighted bar sank and crushed the silky insides around the hard-throbbing shaft and he grunted. The dog grinned then, pushing the bar along the length of his cock like he was emptying a toothpaste tube. When he felt the weight on the end of his long cock he pushed it off his cock and the bar rolled off the bench. The increased weight, pulled the plush body hard off the bench, but with the dog still clutching the upper half the pressure mounted.

The Doberman groaned on the edge of his orgasm until he heard a small ripping sound. He gasped and looked down at the plush otter, seeing flush poking out of a hole in the chest with the rip getting bigger until finally it all came undone. The accelerated rip tearing the plush body in half. The Doberman shouted and shot his cum into the lower half of the otter plushie, with globs of cum covered fluff flying out the other side.

"Oh my god yes! That was amazing." The Doberman looked at the mess he made and sighed, picking up the fluff from the otter's body and using it to clean up the cum he blasted on the equipment and the floor. "I really gotta think about hiring a janitor."
