Slowly, carefully, Lottie slipped out from under her cosy blanket, clambered off her pet bed, and crawled out of her cage, closing the door again as quietly as she could.

Kaspar had given her the spare key to her cage’s padlock for use only in emergencies. She felt a little guilty using it now, but it was in the interest of a fun surprise. She hoped Miss would be amused enough to forgive her.

With the cage locked again, Lottie crept across the carpet on all fours, soon reaching the tree in the corner. She suppressed an excited squeak at the sight of the piles of presents surrounding it - she loved Christmas so much! She stole a glance back at her Mistress, who still lay spread-eagled across her bed, snoring gently. Lottie smiled adoringly - there was little chance of her waking up. Miss was a heavy sleeper.

Still, she was as quiet as she could be as she stripped off the kitten onesie she wore overnight. She reached under the tree and fished out the lingerie she’d sneakily hidden amongst the wrapped gifts a couple of days earlier, slipping it on over her head. The flimsy red material was completely see-through, which was just the way Lottie liked it. No part of her was her own - it all belonged to her Mistress, who should get to admire her property in its full glory whenever possible. But there was no reason that property couldn’t be decorated!

With the lingerie now adorning her body, Lottie retrieved another part of her costume - a long strip of dark green ribbon, which she wrapped around her torso, tying a bow over her belly. She liked the combination of the red and green colours - it was thematically appropriate for the season, and aesthetically pleasing to her. (Not that she knew what either the words ‘thematically’ or ‘aesthetically’ meant.) As a final touch, she put a Santa hat on her head.

Then she nestled between the presents, forming the piles into a rough chair shape, and settled in to wait for Miss to wake up, her legs spread wide and her hands planted on the floor behind her. She badly wanted to open the presents, but knew she wasn’t allowed until her Mistress said so.

As she sat patiently, Lottie’s eyes wandered around the bedroom, having long since grown accustomed to the darkness, and her mind, slow and stupid as it was, nonetheless drifted. She reflected, as she often did, on the glorious six months she’d spent with Kaspar since the day she’d stopped pretending to be Charlotte for the last time. Though much of it was a wonderful blur of submission and arousal, some key moments stuck in her addled brain. Moving in with Miss back in June, leaving most of her belongings behind in her former home and taking only the handful of possessions Kaspar allowed her to keep. The day Mistress had started at college, and they’d moved into their new apartment.

Lottie had relished every moment she’d spent as Kaspar’s live-in slave, which was almost every waking moment. When Kaspar was away at classes or at work, Lottie kept busy cleaning and tidying their home, and doing her own paid work to cover her share of their rent - filming for her OnlyFans account. It was Kaspar’s idea to set it up, and like all the ideas Lottie’s Mistress had, it was a brilliant one. The many pictures of Lottie already drifting around the internet had acted as early advertisements for the exclusive videos, which were proving highly popular. She’d made so much money in such a short time - all of which went straight to Miss, of course.

Kaspar seemed happier and more fulfilled than ever before - she was loving her psychology course, and had made a whole bunch of new friends. Lottie hoped one day she’d get a chance to meet them, but Miss had told her that she wanted to figure out exactly how to introduce her. Though she wasn’t against letting close friends borrow and fuck Lottie, Kaspar wanted to make sure she would be safe.

That was something Lottie had noticed - ever since they’d done away with the Charlotte persona, Kaspar had been a lot nicer to her. She didn’t insult or slap her anywhere near as much as she used to. Lottie missed the abuse, both vocal and physical, because it turned her on - but on some level she understood it was harder for Miss to find it in herself to hurt her now. All those times she hurt her in the past, it was really Charlotte she was punishing. Kaspar hated Charlotte, whereas she loved Lottie. Well, maybe ‘love’ was too strong a word for anything a Mistress could feel for her property. But at the very least, she was fond of Lottie, and didn’t seem to want to cause her any pain. The rare times she did so these days were clearly because she knew Lottie liked it, which the slavegirl appreciated.

Lottie’s dull-witted musings were interrupted by a snort and a groan, as Kaspar woke up. Sitting up in bed and blinking slowly, she glanced in the direction of the tree, and jumped at the sight of her slavegirl sitting in front of it, wearing seasonal sexy attire and a broad smile. Kaspar burst out laughing. “What on Earth are you doing over there?!”

“I’m your Christmas present, Mistress,” Lottie said in her most sultry voice. “Would you like to unwrap me?”

Shaking with mirth, Kaspar scrambled out of bed and strode across the room. “Wow, look at you! You put a lot of effort into this little stunt...” She raised a wry eyebrow. “I think it’d be wrong not to reward that.”

Crouching down, she undid the bow around Lottie’s waist, letting the ribbon fall to one side. “Stay perfectly still while I play with my new toy, Lottie,” she smirked. Lottie obediently froze in place, her toothy smile fixing on her face, her eyes wide and glassy. Kaspar repositioned her rigid arms so they were up in the air, pointing out from her body, like the limbs of a Barbie doll. Then she reached under the lingerie to rub Lottie’s tit with one hand and her slit with the other.

Lottie sat there, keeping as still and frozen as she could, while Miss ran her hands over every inch of her body, finally lying between her legs and sticking her tongue deep in her pussy. But though she could control her body’s movement so well, the slavegirl had more difficulty containing her moans and whimpers of arousal. Her Mistress didn’t seem to mind, though. In fact, she joined in, creating a cacophony of horny noises.

Once she’d had her fun, Kaspar allowed the mewling, panting Lottie to relax and lie on the carpet with her head in her lap. Mistress was even kind enough to fetch a blanket in case she got cold, which was a real risk at this time of year even in spite of the lingering warmth from their amorous activities.

Then, finally, they began to unwrap their Christmas presents. Kaspar had given Lottie an allowance with which to buy a Christmas present for her, and despite her diminished brainpower Lottie had found her way to the local mall and bought a nice grey fedora - Miss had a thing for hats, and Lottie thought the fedora would make her look very sexy. She was quickly proven right when her delighted Mistress tried the hat on, after which she peppered the slavegirl with kisses and tickled the back of her neck to thank her.

Kaspar had got Lottie a new butt plug with a long fluffy tail, to aid with their petplay, as well as a second pet bed. She explained that while the first bed would stay in the cage, the new one could be moved around the apartment, so Lottie would always have somewhere soft and comfy to rest when she wasn’t serving her Mistress - as long as her Mistress allowed her to use it, of course.

Lottie’s final gift was very special. Kaspar had her sit facing her on the carpet and then scoot forwards on her butt (which was not currently plugged), until they were so close that their nipples touched, their legs around each other’s waists. Then, leaning in close and gazing into Lottie’s eyes with a wicked smile, Kaspar whispered, “Open your present.”

A tidal wave of arousal crashed through Lottie’s body in an instant, and she cried out in shock and ecstasy, burying her face in Kaspar’s shoulder. Her arms and legs wrapped tightly around Kaspar’s torso, her whole body clinging to that of her Mistress like a limpet as she tried to endure the sudden, explosive orgasm - the first she’d had in weeks, thanks to Miss’ love of denying her release. Her squirting cunt coated Kaspar’s crotch with her juices.

Finally spent, Lottie sagged in Kaspar’s arms. Miss lowered her to the floor, lovingly stroking her hair and planting a kiss on her sweaty forehead. “Did you enjoy that present, my darling slutty sex toy?”

“Yuh... yes, Miss...” Lottie panted, smiling exhaustedly. “I... I loved it...”

Kaspar grinned. “I’m glad! I’ll use that trigger on you a few more times today, because I’m feeling generous. Must be the Christmas spirit! But after that, no more cumming for a whole month.”

Lottie gulped, already turned on again at the thought of being denied for so long. “I love you, Miss,” she sighed deliriously.

Kaspar’s smirk softened into a warm smile, and she caressed Lottie’s cheek. “I love you too.” Then she straightened up. “I’ll give you a couple of minutes to recover, and then you should call your parents to wish them a merry Christmas, since you won’t be seeing them. My moms said they’d be coming over here at three, so they’ll probably actually turn up around two thirty.”

“OK, Mistress,” Lottie mumbled, already trying to galvanise herself and regain her energy so she’d be ready to serve and obey her owner again.

“Oh, and remember to try and make yourself sound a little more like Charlotte when you talk to your parents,” Kaspar reminded her. “Just so they’re not too suspicious. You don’t have to fully pretend to be her again, though - you shouldn’t have to ever again, unless I absolutely need to turn you back for some reason.”

Lottie smiled broadly once again, utterly contented. She hoped Miss never turned her back into Charlotte. She was truly so much happier as Kaspar’s slave than she’d ever been as her bully.

Strange, how the power of the mind could turn the most vicious hatred into the softest, warmest love.
