The weather had taken a turn for the worse. Normally rain wasn't a huge deal, but this storm in particular was going to be a beast. Emergency broadcasts onto the planet's nuronet urged everyone to stay indoors today. While Epsilon II's weather normally was temperate, it was prone to massive globe-wide storm systems that could last days. Bo didn't mind though, she was in her favorite place - the Animal Shelter. Some of the animals, especially a particular Unakitten, had a hard time dealing with the loud sounds. The building, like all other structures on Epsilon II's surface, was built to withstand any storm the planet could give to it.

She gazed out the window innocently as the rain fell down. Nobody was going to come today, but the Animals still needed a volunteer to keep them happy and safe. It was right up the sweet little Bo's alley! Even among her friends, she was the kindest and gentlest individual around. She always spoke with a soft, meek tone and though she never stuttered it was often hard to hear her. She was a protector of the animals, and spent almost all of her free time helping around town whenever she could. It was fulfilling, especially when she knew her help would make a creature's life easier and better in the long run. Love, care, and attention...

For everyone, with one exception - Humans.

Epsilon II was inhabited by a race of sentient primates called 'Humans' that, with their technology, had been destroying the environment. Naturally, like all the other inhabited planetary bodies, when her kind came years ago the dominant sentient race was 'Subsized'. Epsilon II, known by the Humans as "Europa Prime", was now in it's recovery phase.

And Humans were now bred like livestock, usually so they could be eaten or otherwise forced to serve. People generally didn't kill the little ones unless they were part of a meal though... A family pet, like a small rodent - though a Rodent had far more rights than a Human did. They broke easily, especially when used as toys. That's one of the reason they were bred so often - they were incredibly fragile.

Bo kept it a secret, but she loved the little beings. She could feel one now under her heel... She stood there at the front desk counter gazing out into the storm, gently tapping her heel on the human beneath her foot. It squeaked too much, so she broke it's jaw. It tried to run too often, so she snapped it's legs. Now it just lay there, twitching helplessly as it gazed up to the block of rubber above. It's front had been bruised beyond recognition by the amount of 'Tapping' that Bo had been doing.

Then, the sound of an animal yowling broke her out of her trance... She shifted her weight onto the little human beneath her heel casually, ending it's miserable existence. She could feel its body flatten, squelching out into the tread of her footwear. When she arrived in the back she saw the Unakitten reaching for a little human on the ground. This one had blue hair, and the arousal between its legs had stiffened. It looked like it was in a state of ecstasy or something, but she didn't really think much of it.

"Is that stupid bug teasing you?" She asked cutely, crouching down to look at Mat with a pleasant smile. "I'll take care of it."

She gently plucked Mat from the floor, and was about to toss him into the cage with the creature before she felt his little arousal beneath her thumb. She smirked, letting him roll to his back in her palm before looking over his body again. He was a bit smaller than the other humans she had been used to, but maybe that just meant he was a runt or something. Either way, she was entertained...

"Bo?" Another voice came from down the hall. "Can you come here for a minute! I need you."

It was the resident Vet...

"Coming!" She meekly squeaked. Without hesitating for a second she pulled her left foot free from her shoe and peeled her sock off. Humans didn't last long in there, and it was one of her favorite ways to get rid of the pests. She had other, far more personal preferences but none that she would want to act on in public. Mathew plummeted into the dark, disgusting fabric. The intense smell only fueled his pleasures, causing him to writhe in pleasure as she quickly slipped her foot back in...

Her toes slid over his body, nearly sending Mathew into shock. He hadn't been relieved of any energy for quite some time, so the overall pleasure was simply unbearable. By the time he was safe under her toes, the light cut out... He could feel the insole slide against his back, and her heel slide into place.

Her sweaty toes gripped him, pulling him up a bit and coating him in the smelly liquid. He could hardly breathe...

Something was different here... It still reeked of foot stench, but it was strange... The sweat was a bit thicker, it bound to the little one's skin in almost a layer of gel. The sock absorbed a lot of this, but it was quickly sticking him to the fabric beneath her toes. Bo quickly ran into the other room to assist the Vet, peeking around the corner to see one of the larger animals laying on the table.

"I need you to take notes for me." He said. His skin was a deep red and his horns were like hers, though curled upward. Having a large, fluffy tail like Bo had was extremely rare for her species... It usually just added to her overall cute-factor.

She nodded happily, immediately grabbing the clipboard to start writing.

"Will it be alright?" She asked.

"Oh yes. We'll have the Sanvato back in the habitat soon. I just need you to keep notes as I work."

Later That Day...

Bo had finished her task with the Vet. The storm still had the animals riled up, and she could feel her sweat working on the human she had trapped. Mathew was still alive, but barely... The thick sweat had already melted his skin to the point where he had literally fused into the fabric of her sock. His arousal was still relatively unharmed, but the rest of his body was mixing into the sock's fabric. It wouldn't be long before the sweat dissolved him down into a little puddle, and a stain on the fabric. He couldn't see, but somehow he could still smell and feel - everything. The sweat had another strange property - While it dissolved him, it didn't hurt... It was actually an overwhelmingly pleasureful experience, maddeningly so. He didn't know if that was just the chemical compound breaking down his body, or if it was his body itself...

Bo could feel him stuck there, like a little lump in the fabric. Casually, the cute little girl crouched to pay attention to the Unikitty that was in the medical confinement area. Animal shelters here were incredibly humane, only animals waiting to be examined by a Vet were in the cages. All the others lived in habitats happily, waiting for someone to come by and pick them up. Animal shelters were large facilities, all dedicated to the protection of animals. 'Putting them down' only happened in extreme medical situations, and never due to 'Overcrowding'... It was simply a barbaric idea, one that Humans had been guilty of here.

The little Unakitty let out a happy meow as Bo pulled it out of its cage, bringing it up in her arms for a cuddling snuggle. It's tail happily wagged as the adorable scene unfolded. All the while, Mathew's body continued to dissolve. He could feel the acid eating away into his chest cavity... Soon he would be nothing more than a sentient stain on the girl's sock... That's exactly what he became... He was trapped there, his spirit was not allowed release even after his body stopped functioning. He simply melted into a stain, and somehow - he was still able to smell just fine... To feel pleasure the same, trapped in a state of agonizing joy until those in control allowed him respite.
