The socked paws pushed comfortably against his backside, the toes gripping his cheeks and spreading them out like bread dough off to the side and out of the way. The transformation potion had made him as malleable as before, the meerkat had no difficulties in pressing through the kangaroo's rectum and into his colon, the paws pushing out on the rubbery feeling body, creating six small rounded lumps near the base of the tail.

Once the paws were fully inside the kangaroo, the meerkat began to separate them slowly, letting the almost liquid body morph as she thought about the design. She was in control this time, the roo was far to aroused to have any cogent thoughts about what went where, and winding up with lumpy boots wasn't her idea of a good time. He probably wasn't going to be much better off when he came out of the boots state... but that was two years away. As the tranformee started to lose his features, the meerkat focused on how he would 'lay out' around her paws.

The kangaroo groaned in pleasure as his form began the process of transformation again. Most of his body was disappearing, arms, legs, torso and most of his head began to disappear. He didn't care though, the most important parts remained intact and active. The paws inside him began to squirm about, drawing him apart again, but yet he still felt complete. His sphincter ballooned outwards, thickening up and becoming taller so that it could be the 'leather' rolled boot top. Just like with normal anatomy, his muscles up there would keep things from getting inside his 'body', except the meerkat's socked paws of course.

He felt her paws wriggling, massaging the tract inside and eventually the toes found the prostate, each of the six toes got it's own cushy prostate pad to press against, sending a shiver down what was left of his spine and reverberated through is erect and leaking member. Each step would push them into his pleasurable area, compressing, rubbing and weight would all elicit a thrill with each step.

His groan was stifled by the process, his muzzle closing up and shrinking away, nose narrowing out and wrapping around the toes. The familliar vent had been relocated to just the central toe cap, but still allowed a transfer of air that pushed out and fed all the toes with this refreshing 'breathe' of air. His head sunk down around the paws, his vision returned to a rather comfortable feeling of nothingness, they just didn't exist on boots. Ears folded flat backwards and in, providing an extra outer layer of protection on the side.

The meerkat rocked the roo-boots back on her heels, letting the testicular orbs meld around them to form a protective cap. The roo wouldn't feel any uncomfortable pain when walking, just a comforting touch, as they turned from flesh into a thick urethane. She watched the tops of the shoes, the kangaroo's hide turning into thick leather with steel eyelets and lacing began to spool from them. Once tightened, the laces would act as a 'corset' on the kangaroo, drawing him tight around her paws to avoid slipping.

On the bottoms of each of her new boots, there was still an erection shaped protrusion, one of last pieces to become inanimate. She stood up from the couch, putting her full weight on the roo's member, pressing it into his stomach and flattening it against the rest of the boot. It left an outline, a silhouette of the equine member across the bottom of the sole. Lugs and grip pads appeared, breaking up the cock to it wasn't as noticeable.

The meerkat felt the boots stop moving, the transformation was complete. She gripped the laces and pulled out any slack in the boots, they were a bit larger than normal, as the thick boot socks would be what she wore most of the time. But for now she'd just have to double up on regular socks. They were extremely warm though, but that could have been latent head from the kangaroo's innards that hadn't dissipated yet, but they were far from the cooler previous version.

She walked around a bit, noticing immediately that the sole was much thicker, and it had actual padding, the roos were very thin and were merely an abrasion barrier, but these were comfortable beyond words. Each toe hit a soft padding on landing and as her paw lowered down, the thick member padding pushed gently into her pawbed.

The kangaroo actually wanted to say something, to moan out in pleasure, but there were no longer any lungs or muzzle to let the message carry out. Every step was a shivering pleasure. The paw pushed on his prostate first, sending a gut wrenching shiver of immense pleasure across the bottom of the boot. Ground contact also pushed out a whuff of air from the toes of the shoes, sending it outside the boot and tickling the roos olfactory 'nerve'. Even standing there, the foul socks had some of the air escape, riding slowly across his sense of scent and tantalizing him with the fact that soon he'd get a full whiff.

Her ankle drifted around in his sphincter, rubbing and tugging at it as she walked, it was as if a stern toy was gently gliding in and out of his tail hole with each step. The paws inside rubbed up and contacted the rest of the boot's lining, producing a full thrust feeling when on the upswing and downswing of her walk.

The pressure created on the outside, the movement that massaged his pseudo-cock, sent him into a tear filled grunt. It felt as if he was pushing inside a fresh masturbatory toy, tight and gripping. From the head, down the shaft, to the support ring and then the testicles, there was an invisible ring that had wrapped itself around his head and thrust it's grip downwards, stopping when it caressed his balls, then back up off the top.

Faster and faster she was walking, picking up speed and settling into a rhythm. Her paws pounded the pavement, sending a wave of sensory overload into the kangaroo's form. He'd lost all sense of direction, of being, he still felt needy and extremely pent up. The constant stroking of his cock, the plush prostate pressure, the tailhole stretching and insertion, and finally the scent of the dirty socks pushing out his 'nose'. It was all too much, his mind lost track of time, a concept that he became unfamiliar with as the days grew. All he knew was the intense pleasure that filled his entire being, a perpetual edge the meerkat was walking on. He wanted to orgasm, to have it all end and stop this insidious pestering. But boots don't orgasm, they can't.

********
The meerkat stood at the door, bags packed and ready to go. She scrunched her toes in the boots, letting her toes curl up then relax. Thrill coursed through her chest, the giddy butterflies flapping in her stomach as she crossed the threshold of the door for the last time in a while. New boots crunched the gravel in the driveway and made their way to the vehicle parked.

"Two years here we come!" she grinned, looking down at her new boots and tapping them on the ground. They felt right, they felt... perfect. There were no problems at all, seams, pawbed, nothing. It was his second time in, and the Roo had already achieved a level of 'immersion' that few hope to accomplish. She was sure that he was already 'lost' in the experience, having seconds creep by like days, just mentally wandering and waiting to be walked in.

2 years was going to feel like an eternity. The roo might sink so far in that he won't be coming back... She didn't mind a new pair of roos every few years. Only time would tell though, and there was lots of that to go around.
