My Doctor.

Just as before, The Doctor fell to earth, found a group of new friends, and defeated an alien menace. But not everything is as it should be, Yasmin Khan is not the sweet, well-meaning young police officer The Doctor might have befriended. Instead, gifted with formidable psychic powers, Yaz lives a life of hedonistic luxury, and she wants The Doctor to be hers.

-o-o-o-

The swish of the changing room curtain being flung open finally drew Yasmin Khan’s attention away from her perfectly manicured nails.

She’d been waiting for almost a half hour now, bored and impatient, with no-one but a mouth breather called Ryan Sinclair for company. He seemed to think they’d gone to school together years ago, but she certainly didn’t remember him. Maybe they had, but she refused to waste any time thinking about boring people. She was a woman of expensive tastes and little patience, used to getting what she wanted when she wanted it, not waiting around for other people. It was bad enough she was standing around in a charity shop of all places, but the woman now grinning at her from across the room had insisted.

She still wasn’t quite sure what to think of The Doctor just yet, which was surprising for Yaz. Ordinarily she sorted those she met into two simple categories: those worth her attention, and those too boring to care about.

Ryan, for example, fell firmly into the second category. Honestly when she’d stopped looking at him to impatiently scroll through her emails she’d forgotten he was even there. The Doctor, on the other hand, had still been in her thoughts even as she sighed and rolled her eyes and scowled at her phone.

She was beautiful, of course, Yaz would never waste her time on anyone who wasn’t. Her short blonde bob was bouncy and golden, her smile big and goofy, her body slim but still nicely curved. She was maybe a little plain compared to Yaz’s usual tastes, but she was charming and cute and definitely easy on the eyes.

It wasn’t her looks that Yaz was focussing on though.

The Doctor was… weird. She was eccentric and energetic and talked about strange and impossible things as casually as Yaz talked about shoes or her nails or trips to Milan or Paris. She didn’t seem to care much about politeness or social norms, saying whatever popped into her head and doing whatever she felt like needed doing. She was definitely somewhere on the spectrum, but there was more to it. She talked like aliens and other worlds weren’t just real but something she dealt with every day.

Ordinarily that would have been a dealbreaker, Yaz never stuck her dick in crazy after all, but after everything that had happened in the past week maybe the blonde wasn’t so insane. A supposed alien bounty hunter, a big electric tumbleweed, a freaky space onion… well, Yaz was having a hard time dismissing it all as nonsense. The Doctor was so certain it was hard not to believe her, but even so, she was so strange that Yaz refused to take her at face value.

Yaz still found The Doctor’s oddness more endearing than irritating for now, but it was so unlike her to get so caught up on a woman who wasn’t the kind of perfect beauty she usually deigned to spend time with.

She raised an eyebrow as The Doctor beamed at her and Ryan, arms still outstretched, showing off her chosen outfit.

It was monstrous. Yaz had never seen something quite so ugly before, at least not in the world of fashion. The Doctor had chosen a boxy, androgynous ensemble that suited her eccentric personality perfectly, but was hardly easy on the eyes in Yaz’s not so humble opinion. Blue pants too wide and too short so they showed off her shins but completely hid the curves of her leg. A huge grey coat that covered her from shoulder to ankle. A formless blue jumper with a dull, muted rainbow across it. Mustard yellow suspenders and massive brown boots that were a horror shows Yaz couldn’t even begin to deal with.

“That’s what you’re going with?” She said, the entire ensemble actually making her wince.

The Doctor’s grin widened and she nodded. “Oh yeah!”

“Absolutely not.”

The blonde’s smile faltered. “What?”

“Back inside, I’m not letting you go out in public dressed like that.” Yaz sighed, striding close and steering The Doctor back towards the changing room. The blonde wiggled in her grasp and broke away, pouting.

“Come on Yaz, I like it.” she frowned, playing with her suspenders and swishing her coat around. “On some worlds this would be considered high fashion!”

“Doctor.” Yaz said, voice firm and eyes dark. “No.”

Ordinarily that would be all it took for a person to obey her. The right tone of voice, the right dominant, commanding purr, and any man, woman, or child would happily do whatever she desired. It was the secret to Yaz’s success, why she lived a life of luxury without a job, how she afforded her eye-wateringly expensive wardrobe and her luxurious house in the country and her frequent trips to fashion shows all across the world. She simply told people what she wanted, and they fell over themselves to give it to her.

The Doctor was no different, but Yaz could sense a resistance in her she hadn’t been expecting. Even as the blonde pouted and hung her head, allowing Yaz to slide an arm around her shoulders and steer her back into the changing room, she frowned and mumbled about how much she liked her awful clothes.

Maybe The Doctor really was an alien, or maybe she was just a mutant like Yaz, gifted with abilities usually confined to the pages of comic books. Either way, Yaz finally knew why she’d been unable to dismiss the weird, goofy woman from her thoughts.

She was the one thing Yaz had never had in her life: a challenge.

And Yaz was going to conquer her completely just to prove that she could.

“Well… what’s wrong with it specifically?” The Doctor sighed, staring forlornly down at her boots and tugging at the lapels of her coat.

“Doctor, trust me, this is what I do.” Yaz smiled, staring deeply into the blonde’s eyes until The Doctor blushed and averted her gaze. “Now, let me see what you’ve already gotten whilst you get undressed.”

“N… now?” The Doctor asked hesitantly, “With you watching?”

“Doctor, it’s fine.” Yaz cooed, flashing a reassuring smile and patting the blonde’s shoulder. “It’s just us girls here. We’re friends, aren’t we?”

The Doctor perked up immediately, grinning and nodding her head. “Yeah, course’ we’re friends Yaz!”

“Then you can trust me to dress you properly, can’t you?”

The Doctor’s smile faltered again, conflict evident on her features, but after a moment she shrugged and nodded again. “Yeah… yeah I suppose. You’re a snazzy dresser, I’m sure you know what you’re doing.”

“Great.” Yaz said, waving for her to get on with it, before taking a seat and beginning to rifle through the pile of clothes The Doctor had snatched up but ultimately rejected. Most were ugly garbage just like what she was already wearing, but there were one or two pieces Yaz thought were passable. She had already decided that she would have to take The Doctor to a proper clothes boutique as soon as possible, but getting the blonde into an outfit that wasn’t horrible was the current mission.

She smirked, watching closely as The Doctor hesitated to undress, frowning and pouting to herself before her features relaxed and her mind succumbed. The blonde quickly pried her massive boots of her feet, shed her coat and unlooped her suspenders from her shoulder. She paused for a moment, glancing up shyly at Yaz, hands on her waistband.

“It’s ok, Doctor. We’re friends.” Yaz smiled. “It’s nothing I haven’t seen before.”

The Doctor’s cheeks flushed and she gave a small, embarrassed smile, before tugging her pants down to her ankles and stepping out of them. Yaz’s eyebrow arched as she saw the pair of baggy grey boxers the blonde was wearing.

“What are those?”

The Doctor glanced down at her hips and squirmed uncomfortably. “Er… the shop doesn’t sell underwear.” She mumbled.

“This is what you were wearing under that suit?”

The Doctor folded her arms over her stomach. “They fit better when I was a bloke! Now my body’s the wrong shape.”

Yaz decided not to waste time getting into how The Doctor ‘used to be a bloke.’ She’d tried asking what exactly the blonde meant by that before and gotten no answers, it was simply something she would have to come back to when The Doctor was feeling more… compliant.

“Well, we’ll just have to get you some tomorrow.” She sighed.

The Doctor perked up. “Tomorrow?”

“Well you’re not getting an entire wardrobe here.” Yaz laughed, “This is just to get you something to wear other than those rags you’ve been in. I’ll take you into town and get you some real clothes tomorrow, new shoes, new bras and panties, enough to keep you going.”

The Doctor blushed again, this time even harder than before, and Yaz noted how she tugged on the hem of her shirt, trying to cover herself with the dark blue fabric.

“Doctor… are you wearing a bra?” she asked softly, trying to hide her excitement.

“They… they don’t sell any underwear.” The blonde groaned, “None at all! I was a man yesterday I wasn’t expecting this to be an issue! I don’t even know how to start! Are there bra shops? Different types? How do I know what size I’m supposed to get?”

Yaz couldn’t help but grin, standing up and pulling The Doctor’s hands away from her shirt. “It’s ok, Doctor, I’ll help.” She promised. “I can take your measurements now, if you like.”

“I don’t know… we only just met.” The Doctor mumbled.

Yaz squeezed her hands, forcing the blonde to look at her, and once she did she found herself staring deeply into the rich brown pools of Yaz’s eyes. Her torn, embarrassed expression relaxed, her pupils dilating and mouth hanging open just a little, as Yaz’s words flowed over her like the tide.

“It’s alright, Doctor, you can trust me. I’m your friend. I know what I’m doing.”

“Of… course.” The blonde repeated quietly. “You know what you’re doing.”

As Yaz sat back down and returned to innocently sorting through the pile of clothes The Doctor had compiled, the blonde swallowed and lifted her shirt. Part of her was horribly embarrassed. She’d never had breasts before, but she knew well enough that showing her boobs off to someone she’d only spent a day or two knowing wasn’t considered normal on earth. She really wanted to be Yaz’s friend, to be friends with all of the people she’d met in her short stint of existence. What if flashing her new body made Yaz uncomfortable and their blossoming friendship stalled right out of the gate?

Another part of her, a strange, secret part she didn’t even know how to describe, was eager to see Yaz’s reaction. The beautiful young woman had offered to measure her, after all, but what would she think about The Doctor’s breasts beyond that? Were The Doctor’s first ever set of boobs good ones? Were they what humans liked? The right shape, the right size? Did Yaz think they suited her body, or would she disapprove just like she had of her clothing choices?

If Yaz liked her boobs, how would she behave? Would she blush and avert her gaze? Would she smile and flirt with The Doctor? How would she talk about them? How would she get her measurements, would she touch her, and if so, how? Would she be gentle, careful, her fingers brushing over The Doctor’s skin as she made the mental calculations? Or would she be aggressive, strong, dominant? Would she grab hold of The Doctor’s boobs and squeeze her, feel her up, take advantage of the situation to explore her soft new chest?

The Doctor cleared her throat, cheeks burning at the thought, as Yaz continued to work through the clothes, not even looking at her yet. She dropped her shirt and shivered in the cool air, noticing how her nipples tingled and stood to attention on the soft mounds that now swelled from her chest. Being a woman was going to take some getting used to, but she had to admit she liked the view.

“Um… so, how does this work?” she asked after a few moments of anxious waiting.

Yaz looked up at her, eyes darting between her face and her chest, a smile coming to her face that made The Doctor’s hearts race.

“You look so nervous, relax!” Yaz laughed, “I won’t bite.”

The Doctor laughed too, still very nervous despite what the younger girl said, covering her nipples with her palms. “Sorry… new experience. I think I’m quite socially awkward now, being naked probably doesn’t help. I used to be above all this self-consciousness, insecurity about my body, I wonder if it’s because I’m a woman or if it’s just the new me?”

“You’re not self-conscious because you’re a woman.” Yaz sighed, standing up and gesturing to herself. “Do I seem insecure?”

“Well, no… not really.” The Doctor admitted. “But you’re a beautiful young woman, you’ve spent all your life growing into your body, I only just saw myself in a mirror a few minutes ago.”

Yaz smiled at the compliment, taking The Doctor by the shoulder and spinning her around to face the floor-length mirror against the wall of the changing room. As The Doctor blushed and fidgeted, she gently grasped her hands and brought them down to her sides, keeping them pinned by her hips just forcefully enough to keep the blonde in place, but not enough to alarm her.

“You look beautiful too, Doctor.” Yaz said, “Look at your face, look at your body, you have nothing to be insecure about.”

“Really?”

The Doctor looked so cute and hopeful Yaz wanted to take a bite out of her, but she restrained the urge to lock her lips onto the blonde’s slender neck, and instead released her wrists.

“Of course, now hold still.”

Yaz always carried a tape measure in her handbag, it was a practical necessity when so much of her time was spent revolving around fashion, and in no time at all her slender fingers were stretching the thin white band across The Doctor’s heaving bust.

“Oooh!” the blonde squeaked, “Cold!”

“Hold still, Doctor.” Yaz tutted sternly, hiding her smile behind The Doctor’s head as her hands brushed the pert little mounds of the blonde’s bosom. Her breasts were nice, but nothing spectacular, two small perky swells each capped by an adorable rosy nipple. Yaz preferred her women bigger, but again that was something she could address once The Doctor was ready to listen to her properly.

“34B.” she said finally, letting her breath blow over The Doctor’s shoulder, lips just a little bit too close to her to be appropriate. The Doctor only shivered, flesh raised to goosebumps as she blushed and admired herself in the mirror.

“Is that… good?”

“It’s your size, what do you think?” Yaz chuckled.

“I think they’re nice, they suit me.” The Doctor decided, encouraged, only for her face to fall as she saw Yaz’s condescending smile. “Don’t they?”

“You’re a little on the small side, the national average is 36DD.” Yaz shrugged, feigning disinterest, “But your opinion is what matters.”

“Right.” The Doctor smiled weakly, staring a herself in the mirror again. What would she look like with bigger boobs? Would they suit her better than her current size? Looking back on it a lot of her friends and companions had been bigger than her, she really should have asked about their experiences. Though maybe that wouldn’t have come across quite as intended whilst she was a man. Didn’t big boobs hurt women’s backs? She thought she’d heard that before, but River had never complained and she’d had the biggest breasts out of all The Doctor’s friends, as the blonde fondly remembered.

“I can measure your waist and hips whilst we’re at it, if you like.”

The Doctor blinked, realising she’d been ogling herself in silence. “What?”

“Whilst we’re here, I can do all your measurements.” Yaz repeated, “It’ll save us time tomorrow.”

“Oh, ok. Sure!” The Doctor nodded, “Measure away!”

“As you wish.”

Yaz hummed quietly to herself as she worked, mind racing with the possibilities of what she could put The Doctor in. Her petite frame and stature would suit cuter, girlier ensembles, things that would compliment her flat chest and nubile hips. She wondered how far she would have to push The Doctor to convince her to slip into thigh-high socks, a short skirt, a crop top and a cute choker? Hell, how much work would it take to get her to put on some cat ears as well?

She grinned, palming the blonde’s slender waist as she noted down the data.

Maybe if she filled The Doctor’s figure out a little, she’d be perfect for fully glamming up. She pictured a low-cut cocktail dress, glittering and seductive, clinging to her curves and showing off plenty of leg and cleavage. If she fluffed out the blonde’s lovely hair and put on a little make up, she’d be Hollywood beautiful, perfect for hanging onto Yaz’s arm at a runway show.

“Let’s take off these ugly things.” Yaz purred, grabbing The Doctor’s boxers and tugging them down before she could complain.

“Eeek! Yaz!” The Doctor squeaked, mortified, her hands flying to her womanhood as Yaz pulled her underwear down to her ankles.

“It’s ok, I just need to be able to measure your hips and legs.” Yaz said, “Don’t be shy.”

“I… I don’t know.” The Doctor frowned, “This feels…”

“It’s ok, Doctor. Don’t be shy. You have nothing to be embarrassed about.” Yaz said firmly, “Show me, and I’ll tell you what I think.”

The Doctor hesitated. She felt like this was definitely not what was normal when shopping for clothes. Surely women didn’t always have to strip naked and let employees see everything when they got measured? But Yaz seemed so confident, and just from the outfits she’d seen the girl wear The Doctor knew Yaz had an eye for fashion.

Besides, she was curious to hear what Yaz thought about her… well, her vagina.

She raised her hands awkwardly, biting her lip as she looked at her reflection. Like usual she’d regenerated with a little body hair, a soft blonde fur over her crotch and around the warm pink lips of her new genitals. She had some fuzz under each arm as well, but beyond that it seemed like she was a lot less hairy than previous bodies, which was a relief. It was always a lottery when it came to how a new form would look, sometimes new hair would sprout where it hadn’t before, and sometimes she’d even lost some after the revitalising glow had died down.

As far as she could tell, her womanhood was perfectly ordinary, but she had yet to work up the courage to investigate it properly.

She gasped as Yaz brought the tape measure up towards her crotch. Was she about to touch her there? That intimate spot even she hadn’t explored yet? What would that even feel like? How would Yaz do it?

Her terror and anticipation faded into a mix of relief and disappointment as Yaz simply pressed against her inner thigh, terribly close to The Doctor’s blushing lips, but not actually touching them.

“There we go, now we’re ready for tomorrow.” Yaz said brightly, straightening up and patting The Doctor on the back. “Are you alright, you look a little flushed?”

“Oh… oh I’m ok.” The Doctor stammered, “It’s just a little embarrassing is all.”

“Well we’ll get you covered up in a moment.” Yaz laughed, “Just let me see if there’s anything outside that’ll suit you. Wait here.”

As she turned and left through the curtain, she couldn’t contain her grin.

Ordinarily, Yaz didn’t do charity, or second hand clothes, but eventually she had scoured through the rejects of The Doctor’s pile, along with every rack and shelf in the building, and assembled something she could stand to see The Doctor wear.

In just a minute or two she’d gotten The Doctor covered up, much as she wished she could have left her nude, watching closely as the blonde slipped into what Yaz had chosen for her. It was almost as good as watching her strip, seeing those cute tits bounce and that tight ass jiggle as she struggled into her new wardrobe, blushing and fidgeting all the while.

Yaz had resisted the urge to put The Doctor in something overly slutty just to see what she could get away with, instead choosing something light and feminine, but hardly conservative. Anything was an improvement over the disastrous first ensemble, but given the limited options she’d had, Yaz was pleased with the result.

The Doctor was now dressed in a simple, pale pink blouse that fit loosely over her frame. It’s wide collar showed off the blonde’s chest and neck, where a cheap yet cute necklace Yaz had found was resting. A short, light grey skirt hugged the Doctor’s waist and hips, again light and floaty, showing off her legs from the knees down. On her feet were a pair of simple white pumps, the best Yaz had been able to find out of the charity shop’s dire collection of footwear.

“What do you think?” she asked, watching The Doctor closely as the blonde admired herself in the mirror.

“I look so… pretty.” The Doctor grinned, “Wow, I never knew how nice being feminine felt!”

“I’m glad you like it.” Yaz chuckled, putting just a little power into her voice as she stepped up behind The Doctor and casually adjusted her top. “You do like it, don’t you?”

The Doctor’s grin widened. “I do!”

“Good girl.” Yaz breathed, just softly enough The Doctor didn’t hear, before she put a hand on the blonde’s waist and steered her towards the curtain. “Now, let’s go home.”

“What do you think, Ryan?” The Doctor smiled eagerly as they stepped out into the store.

“Wow Doctor, you look like a whole new person.” The poor idiot grinned, eyes drinking in the blonde’s figure from head to toe. Yaz rolled her eyes and patted The Doctor’s back to regain her attention.

“Tomorrow we’ll get you everything else you’ll need.” She promised, leading The Doctor past Ryan towards the door, shooting a cold sneer over her shoulder as she pushed her new plaything out into the street. “Clear up the rejects and pay for us, it’s the least you can do.”

Ryan’s eyes glazed over in an instant and he silently trudged away, leaving Yaz to take her prize home in peace.
