Abby

Abby padded through the narrow hallway alone. Her paws clicked against the wooden floor before she stopped and sat in front of A closed door. She opened a single eye as wide as possible to peer through the keyhole.
Her trainer was with his girl again. The two were mating furiously on the bed that both he and Abby slept on. Her trainer had his mate pinned against the bed, she laid on her back as her legs crossed around his back, holding him close as he pumped in and out of her.
"sh-shit! I'm about to cum!" the trainer abruptly shouted.
"no! no! pull out! pull out!" as she yelled her demand her legs straightened and pulled back and kicked at him with all the strength she could muster. Abby's trainer groaned as he pulled back, his member covered by a thin latex as his cock twitched out in the open, his potential climax reduced to a mere spill.
"phew! that was close!" his girlfriend said as she got up, already getting dressed. Abby could smell her trainer's dissatisfaction while he pulled off the condom and threw it in trash bin.
"y-yeah, close one" he said, obviously repressing his true feelings as he began to look for his pants
Abby was happy when her trainer opened the door and pat her head.
"I wish you kept your Pokemon in its pokeball. It's filthy to keep them loose in the house."
"No it's not, I give her baths and she's house trained! I don... err" His girlfriend gave him a stern look of disapproval. He knew there was no fighting it, she wasn't mad about Abby. She was mad about him talking back and disagreeing. Abby sat next to him and looked up, a pang of fear shivered through her when she saw his hesitation. She knew her master didn't have a spine and usually he obeyed her every demand.
"... fine I'll go buy a pokeball soon for her"
"No, that isn't good enough. Come on, we're taking her to the clinic."

Abby didn't know what the clinic was but she was glad to be in her trainer's car again. She sat in the back, her sharp claws and horns poking dangerously against the thin leather seats. They eventually slowed to a stop and her trainer got out and opened the car door for Abby.
"We don't have to do this." Her trainer said while they waited inside the building.
"Of course we do, the sooner the better! It's poor hygiene to have a Pokémon walk around the house acting like it owns the place!" Abby knew she was the subject of the argument again. She whimpered while sitting on the immaculate white floor. She rested her head on her trainer's knee who merely looked down with somber eyes.

"Sir, you're up next" The receptionist announced. Abby's trainer stood up and led Abby to the back. There a man wearing latex gloves and a white lab coat readied the flat seat where Abby was soon lifted up to rest upon.
"Is there a particular reason you'll be doing this today?" Asked the vet.
"Yeah... I can't keep her anymore and I don't have anyone else willing to care for her."
"Such a shame..."
Abby didn't know what was going on. Her trainer knelt down to hug her though which brought her some relief. She even smiled when he petted her atop the head and rubbed her head horn.
"I love you Abby..."  He muttered before nodding to the vet.
Abby felt a prick along her backside. She jumped up but her trainer held her down.
"I'm so sorry..." He sobbed. She saw that he was crying now. But why? Her anxiety and beating heart soon relaxed though while her muscles grew lazy. She felt tired... She just wanted to nap now. She smiled when she felt her trainer smooch her one last time before drifting off to a sleep that she'll never wake up from...
