Her costume's debut

"Oh, hey. Let's go get some candy from that house there." The serval pointed, and Cathy's head snapped around to follow her gesture. A handful of decorations were hanging outside what looked like a modest suburban house with a simple door and a lawn decorated with pumpkins and fake skulls of various species. There was nothing especially elaborate about the display, but it was enough to draw Jada's attention.

"You ready for your costume's debut, girl?" The cat walked past her and tugged on the leash, pulling the dog towards the house.

Cathy stumbled behind her, struggling to keep up with Jada's tall strides while on her fours, her tail rigid and trembling in the air. "Jad, are yo—"

"Shhhh," the feline hushed her, making a shushing motion with a paw. "No talking. Pets don't talk, remember?"

The canine kept her mouth shut and trudged on, following her roommate into the front yard. She glanced around nervously as they approached, the lights of the nearby streetlights reflecting off her sleek, dark coat and causing her naked fur to shimmer. Fully clothed and undeterred by modesty, Jada padded right up to the door confidently and knocked, a bright smile on her muzzle. The two waited a few seconds before the door opened, a young couple peering out, their eyes running along Cathy's nude body from head to tail.

"Trick or treat!" Jada chimed, her ears perked with excitement.

"Ah, hi! Happy Halloween!" The male husky's eyes lingered on the collie, his ears flushing a bit. "You're... uh..."

"She's my naughty puppy!" Jada exclaimed, her tail flicking back and forth.

"Aww, that's cute!" the female raccoon said, her eyes lighting up. "Has she been a good girl?"

"Well, I'm still training her," the serval fingered the leash in her paw, "but it's hard to be disappointed with such a sweet little canine." With a grin, she yanked lightly on the collar, drawing the collie's attention. "Why don't you show them how obedient you can be? Cathy, stand!" She tugged on the leash again, and the dog reluctantly stood, her paws slapping on top of her bare breasts and clenching her thighs together.

"Ah ah ah," Jada scolded, passing the leash to her hand holding the pumpkin bucket and lightly smacking the collie's hindquarters with her free paw. "Don't hide that lovely little package from them. Show them everything."

Cathy groaned quietly, but did as she was told, uncurling her fingers from her chest and spreading her legs slightly. Her ears flattened against her skull and her paws hung loosely by her sides, unable to meet the pair's eyes.

"Wow," the husky murmured, his eyes tracing over her body once more. "That's... um..."

"Perfect!" The raccoon cut him off, digging a paw into a bag of candy. "Let's give her a treat, shall we?" The woman produced a large chocolate bar and approached the naked canine, a broad smile on her muzzle. She reached up and began enthusiastically petting Cathy's head, cooing softly while she pressed the wrapper into the border collie's snout.

Cathy tensed at first, but then relaxed, allowing the other woman to stroke her head while her maw opened and accepted the candy bar, inadvertently letting out a pleased "wuff" sound. Her tail began lightly sweeping the air, her resistance faltering as the raccoon continued to lavish attention upon her.

"Good girl!" the woman whispered in encouragement, smiling widely at her. "Hehe, I love dogs. My fiancé's the same way with pets." She gave the collie a warm nuzzle under her chin before moving away.

As Cathy watched her wave goodbye and slip back into the house, Jada slipped the candy bar from her muzzle and motioned for her to kneel back down. Slipping the chocolate into her bucket and taking control of the leash again, the cat ordered, "C'mon, girl. Heel."

With some nervous fidgeting, the border collie obeyed, sinking back to her knees at Jada's side, her ears splayed as her ever-present embarrassment regarding her subservience lingered. Not even sure why she was doing it, Cathy found herself lifting her tail just like her friend ordered to before, almost immediately regretting the decision as the cold wind sought fit to give notice that she was moist between her legs. She was starting to develop confusing feelings about being the serval's "pet", and in her current state, it seemed she wouldn't be able to keep that fact hidden for long.
