Author's Note: Welcome to a brand-new Doctor Who story, featuring the brand-new beautiful broad in the drivers seat. Jodie Whittaker is absolutely stunning, and I personally think she is easily the best thing about the new series. She had such an energy in what essentially amounted to a series of stale stories, making even the boring parts seem remotely interesting. Plus, she's a lot easier on the eyes than her previous incarnation. No shade on Capaldi, but there really is no competition.

So, whilst Clara and Amy's stories focus on straight sex between the Doctor and the companion, this story will be strictly lesbian. And if there is a cock, it will probably be in a threesome scenario and only ever used to enhance the lesbian aspects. And thus, I will be taking some liberties with the story. I won't be following the episodes and will instead focus on in between the episodes and other naughty hijinks through time and space. Don't want to spoil everything, but essentially a Doctor/Yas, adventure through time and space, with occasional visits from previous companions.

And thus, as a prologue, I want to ignore the new Doctor (I know, why make a story about the new Doctor and not feature her in the first chapter). Primarily, because this is a prologue, setting up future stuff. It also happens to be a commissioned piece that I don't really have a place to upload. It features Bill/Heather. If you want to skip straight to a fun chapter with thirteen, go to the next chapter. So, without further ado, enjoy!

Prologue: Girls Do It Better

The club was dimly lit, as per the norm, but Bill could still make the girl out. It helped that they had run into each other only moment's before, the both of them nervously bowing their heads before moving on, but Bill kept a close eye on the young round-faced girl as she lingered at the bar. She was delectably sweet looking, and Bill felt herself become ever so slightly infatuated. It helped that she had knocked back a few drinks and her thoughts weren't as clear as she'd like, but she felt something for the girl. Maybe it was momentary lust or maybe something more. However, she wasn't subtle with her ogling. Not entirely.

Their eyes met once more, the woman looking back at Bill with a soft smile before blushing gently. Bowing her head, she returned to her conversation with her friends, increasingly conscious of Bill's gaze. Not in a bad way. Her cheeks flustered, and her heart began to race, as she returned the interested looks, occasionally catching Bill's eyes as she looked up and down nervously, trying not to get caught again. Finally, Bill felt the urges within her come to the surface and she finished her drink, sliding it onto the table and leaving her friends to themselves.

Moving across the club, Bill kept her eyes latched onto the woman. Without missing a step, she crossed over to the girl's table and stood before her nervously. Her friends giggled as Bill shuffled back and forth on her feet, but she held her ground. Smirking, the girl tried to quieten her friends before turning to address Bill. Breathing heavily, Bill found her confidence and offered the girl her hand, "Would you like to dance?"

"Erm… I… Yeah… I guess. Sure, why not?" the girl smiled nervously, glancing to her friends as they stifled their chuckles. She took Bill's hand and allowed the dark-skinned girl to guide her towards the dance-floor. The music was perfect; low and subtle, but powerful enough for a good dance. Bill dared not to pull her close. Despite the sudden burst of confidence in asking her to dance, she still felt a little… uncertain around girls. And well… her nerves got the better of her. Still clasping the woman's hand, she gently began to move to the music, eventually snaking her hand towards her other hand and holding both of them. Moving in tandem, the blonde girl lifted her head and asked, "You've been looking at me all night, haven't you? I don't even know your name…"
"I'm pretty sure you've been looking at me as well. Or have I been awkwardly avoiding your gaze for nothing?" Bill retorted, receiving a chuckle from the blonde as she smiled softly, her eyes warming to the coloured girl. She had peculiar eyes. Beautiful eyes. One was like a star and the other a deep blue, both large and round; dreamy. The two naturally drifted closer, their hips moving together as they eyed each other up, "I'm Bill by the way. And before you say, yes, I know, it's not exactly a normal name. Well, it is a normal name, just not for girls. I didn't choose it, I'm not like… Well, I'm not. You know… I don't know. It's… just my name."

"I like it. It's a little… different. Better than being called… I dunno… Emma. Everyone's called Emma. Never met a Bill. Well, a… a girl Bill…" Heather blushed, stammering towards the end as she bowed her head nervously, the woman more anxious than Bill. Taking the lead, Bill bolstered her confidence, trying to exude some of that confidence over to the girl. A few more minutes of fluffy, casual dancing and she finally piped up once again, smiling as she looked to Bill, "I'm Heather, by the way."

It was strange. That moment melted away, the two of them looking into each other's eyes. To this day Bill couldn't exactly explain what happened next, and really didn't want to. It just happened. The two almost lunged at each other, their lips colliding, gently at first. The soft sound of their lips touching was heard by only them, the two of them staggering through the small dance floor to the back of the club, their faces slumped into the shadows, their lips still battling against one another, passionately kissing each other. Their bodies pressed up against each other, their breasts squeezing together through the thin fabric of their clothing. Bill giggled into the kiss as she felt Heather's rock-hard nipples prod her sensitive flesh, the two of them no longer caring about nerves.

A few eyes in the club followed them and a few voices cheered as they ogled their lesbian embrace, but soon enough, alcohol took their focus, allowing Heather and Bill to make out in peace. Bill's hand curved around Heather's petite waist, pulling their crotches together, their lips fighting harder against one another. Moaning softly, Bill parted her lips, her tongue lunging forwards and exploring Heather's mouth. Eager to do the same, Heather mimicked Bill's movements, her own tongue battling Bill's as the two of them began to grind against each other, their crotches sandwiched together and brief, fleeting tickles of pleasure running through their bodies. Finally, they pulled apart, the lusty passion lingering in their eyes until they both began to giggle. Smirking, Bill said, "I would never have taken you for that kind of girl. I would have picked you out as a little more reserved. A bit above a snog in a seedy club… Glad I was wrong…"

"Reserved? I… Well, depends whose company I'm in. I can be as forward as any other girl," Heather blushed meekly as she bowed her head nervously. Smiling softly, Bill lifted Heather's chin up, bringing their lips together once again, only softer this time.

"Show me…" Bill purred as she pulled away, causing Heather to smile in response. It was as if those words were the go ahead and Heather was now let off the leash. Glancing over her shoulders, she made sure that they were relatively alone. Turning back with a salacious smile, the blonde's eyes travelled down to the pair of black skinny-jeans Bill had on. Without even thinking, Heather quickly unbuttoned them, allowing herself enough space to wriggle a hand inside them and down to Bill's quim. Before the coloured girl could even realise what was happening, Heather was already tracing the outside of her thin cotton panties, collecting Bill's juices on her fingers. Pinning her body against Bill's, she hid her hand away from any prying eyes, her eyes latched onto the bald patch of skin that was now on show behind Bill's trousers. Shaven. She couldn't quite get a good look at the girl's pussy, but Heather could feel ever fold and crevice. And in her mind, that was enough.

"Oh, my… That's… Definitely forward… oh fuck… That's… Right there…" Bill moaned, clutching the small bannister that ran along the outside of the room. She could feel Heather's finger indent through her panties, tracing her cleft with an adept explorative touch. The fabric quickly became sodden as she teased her more and more, brief fluttering gasps of pleasure rippling through her folds. Heather's other hand grabbed onto Bill's breast, squeezing it through the fabric of her top and noticing the girl's lack of bra. Some women were lucky enough to not need one and the inherent perkiness of Bill's petite handfuls was more than enough to not require one. Pinching her tiny nipple through the fabric, Heather used her own body to hide their illicit activity as Bill watched the rest of the room, her lips permanently parted in a soft and delicate moan.

"Maybe a bit too forward? Should I stop?" Heather asked, slowly pulling her finger away and trying to wriggle her hand out of Bill's panties. Bill was quick to lunge her own hand between them, holding Heather's wrist in place as she hungered after more pleasure.

Taking the hint, Heather slipped the finger back into place, only this time, she slid her hand down inside Bill's panties, feeling the heat of the young girl's pussy against her hand, her finger quickly becoming drenched in Bill's arousal. Curling the tip up against Bill's entrance, Heather wasted no time in sinking the entire length of her index finger inside Bill's clutching wet cunt. Her tight folds clung to her digit as she pushed it deeper inside, jamming it all the way inside Bill's eager hole. Bill's breath caught in her throat as she felt Heather slide her finger inside of her. In Bill's case, a finger was hardly a rarity when it came to what found its way between her legs. Lonely nights made it an easy option and thus a common one. It was safe to say that a finger was miniscule in comparison to what her pussy could take and when alone, she would never even both with a single one. Yet, when it was someone else finding their way inside her cunt, the pleasure was amplified by the erotic nature. Not to mention Heather's breath on her neck and just how skilled the blonde's hand was. Moaning softly, Bill looked to Heather, eager to see more of the blonde girl and vice versa, "I've got the house to myself tonight… It's a bit early, but? Well… We can hardly finish this on the dance-floor, can we?"
"I don't know. I'd love to see you finish on the dance-floor… But lead the way…" Heather smiled sliding her hand out from Bill's jeans, causing the coloured girl to groan. Lifting her slick finger to her lips, Heather dipped it inside, tasting Bill's pussy on her tongue and moaning softly to herself. Turning to go grab her stuff from the table, Heather left Bill enamoured on the dancefloor, her jeans undone and her shaven crotch on display. It took Bill a couple of steps to realise and button up. Grabbing her jacket and bag, she led Heather out the door and the two walked swiftly through the city, both of them on the verge of running in anticipation for what was going to follow.

Eventually the two of them found their way to Bill's front door, and only moments later, they were inside . Ditching her keys and jacket, Bill walked through the flat switching on lights as Heather stood nervously in the doorway. Moving through to her bedroom, Bill sat on the edge of the bed as Heather teetered by the door, anxious. Finally noticing her nerves, Bill piped up, "You okay?"

"It's just… I never really do this. Well… haven't done before… The whole…" she began, giving Bill a little worry. She had presumed that Heather was a lesbian but hadn't really planned for the option where she was a virgin. Or not a proper lesbian at all.

"Not with a girl? Oh… That's alright. I'm very accommodating. Don't mind a little experimentation. That's all my foster-mother thinks it is," Bill laughed, leaning back ever so slightly as Heather shook her head, taking a step into the room, all the while blushing.

"No, the whole… Club meet-up thing… It's a little… nerve-wracking… It's really not something I do," Heather smiled softly as she brushed a strand of hair out of her eye, the glint of her sparkling star-like eye enthralling Bill once more.

"Hey, don't worry. Everyone gets a little nervous. Hell, you can imagine what it took to walk up to you. What about being forward? You certainly seemed to have the knack of it in the club," Bill smiled, reaching forward and taking Heather's hands in her own.

"I don't know. I suppose that's the kind of person I want to be. Confidant. Forwards. Bold…" Heather smirked, comforted by Bill's warm smile and the arousal that was growing between her own thighs. She wanted Bill, but just didn't have the guts to pull her close, plant her lips on hers and fuck her like an animal.

"Well, that's the beauty of meeting at the club… I know next to nothing about you. For all I know, you could be that girl. Tonight, we can be anyone we want to be. We can be as confidant, forwards and as bold as we want," Bill smiled, leaning slowly forwards and capturing Heather's lips once again, the slow and steamy passion bleeding over into the young blonde. They held there for a few moments, their lips tenderly massaging each other before Heather pulled away sharply, sliding her hands out of Bill's and standing in the middle of the room. Worried that she had pushed to far, Bill was quickly calmed as Heather dropped her purse to the floor and adopted that same salacious smile that had spurred Bill's heart on in the club.

She wasted no time in grabbing the hem of her blouse and tugging it up over her head. Chucking it to one-side, she stood in the middle of the room, her creamy white flesh exposed, with her breasts hidden away behind a small lacy white bra. Not missing a beat, she grabbed her skirt and tights, pulling them both down to her ankles in one go, kicking them to the floor with her shoes and standing in-front of Bill in only her underwear. A matching lacy pair of panties with a tiny pink bow on the front. Soaking her in, Bill ogled her soft skin and the delicate curves of her hips. She was a rather small, petite woman, but was surprisingly… voluptuous. Her hips were curvaceous and accentuated her body, with her panties hugging her curves nice and tightly. Bill hadn't been able to sneak a look at her arse, but she could tell already that it was going to be perfect for her. Round, full, and the just the right amount of juicy. Enough to grab hold off at night. And then there were Heather's tits. They weren't massive, but they looked gorgeous on her thin, small frame. On anyone else, they would have appeared tiny, but on Heather they looked bouncy and delightful. Maybe it was the bra, but Bill didn't care. She was horny and needed one thing and one thing only. To be fucked.

With a wry suggestive grin, Bill leant forward and hooked a single finger inside Heather's panties. Pulling her over by her underwear, Bill dragged on top of her, the young blonde straddling her as Bill's hands roamed around to her rear. She was entirely right. Just juicy enough. Their lips leapt against one another, crashing softly together as their hands began to roam up and down their bodies. Bill lunged to Heather's bra, unfastening it and chucking it to one side, her hands immediately grasping the blonde's plump breasts, moaning as her fingers sank into the soft creamy flesh. Heather tugged Bill's top up and over her head, freeing the coloured girl from the constraints and similarly pawing at Bill's pert boobies, tweaking and playing with her stiff, rock-hard nipples.

Rolling to one side, Bill pinned Heather against the bed, planting her knee in between the girl's thighs as they continued to kiss. Peeling away Heather's panties, she rolled them off her feet and pressed one of her hands against the blonde's pussy, immediately feeling her slickness drenching her fingertips. Grinning madly, Bill allowed herself to be stood upright, with Heather sitting on the edge of the bed, eye-level with her crotch. Nimbly unbuttoning Bill's jeans, Heather slowly pulled them down her legs, revealing the object of her desire and previous probing fingers. Her deliciously slick quim was directly in front of her, glistening and gleaming, begging to be devoured by hungry lips. Heather robbed herself of that delight, instead removing all of Bill's clothing and admiring her naked body. As much as Bill would disagree, she was gorgeous. She was a little boyish in areas, but her tall, slim frame allowed her perky breasts and round, pert bum to truly sing. Not to mention the perfect complexion that gave her nipples a deep, dark, chocolaty colour and the amazing side-effect of being near-irresistible.

The passion wore off for a moment as the two of them simply admired each other's bodies. Whilst both of them wanted nothing more than to be submerged between the other's legs, set loose to devour their partners gorgeous folds, they spared a moment to lustfully glare at each other's sweet and supple skin. After all, even the most appetising meal deserves to be admired visually at first. Neither one of them wanted to make the first move, with them both strangely content with the eye-candy in front of them. Bill's eyes drifted down between Heather's legs, noticing her neatly kept bush. It was trimmed and well maintained, with not a single hair posing any difficulty in diving in. Whilst it was thick and bushy, it was only adorning her crotch and nothing more. Her slick quim and desirable folds remained open and unhampered. The perfect thing for a little oral attention.

Before Bill could do anything, Heather made her move. Pulling Bill onto the bed, she flipped her onto her back before crawling between Bill's dark thighs. Looking up across her body, Heather smiled, admiring the soft rise to her chest and the proverbial towers that were her two nipples. A part of her wanted to abandon Bill's pussy and nibble on her desirable teats all night long, but Heather fought the urge. It was like she was at a buffet, with all the choice In the world. Spreading Bill's legs wider, Heather silently remarked at the girl's flexibility. Bill had gotten used to spreading herself like that. The few girlfriends and hook-ups she had were always made better by being limber. Allowed tongues and fingers to get deeper than ever before. And that was never a bad thing. There were nooks and crannies deep in Bill's body that could make her scream like an animal, were they only played with a little.

Running her hands along Bill's soft thighs, Heather leaned closer, her lips hovering near Bill's pussy, the heat from her folds lingering in the air as she threatened to kiss her sensitive entrance. Bill's eyes were transfixed on the blonde's, eager to see her lips buried amongst her own, delving into her sweet hole. Wasting no more time, Heather extended her tongue slowly, gently tracing the outer folds of Bill's dark and delectable pussy. Curling beneath her labia, Heather felt Bill open like a flower, her folds peeling apart as her tongue began to lavish every inch she could find, savouring the taste of the coloured girl on her tongue and watching as her juices began to dribble down Bill's ass cheeks, leaving her crack a shimmering, glossy sheen. Threading her tongue through Bill's folds, Heather coaxed the girl's clit out from it's nestled location, giving her free unrestricted access to the swollen hive of pleasure.

Snaking her tongue around the small and sensitive bead, she flicked back and forth, batting the small morsel of flesh around with her slick muscle, all the chorus of unbelievable moans from Bill. Her lips were permanently parted as she watched Heather toy with her intimate areas, her tongue darting back and forth expertly, finding those unique ways to make her squirm. Bill's eyes travelled a little further down, ogling the arch of Heather's back and, more importantly, the curve of her ass. That sight, framed by Heather's probing tongue and hunger for her pussy, made Bill shiver with anticipation. Even though the pleasure was building in her core, the young woman knew that this was only the beginning of a toe-curling evening.

Desperate to make Bill writhe and spasm with unadultered pleasure, Heather slipped her tongue a little lower, weaving it into place against her entrance. Her hands, which were massaging Bill's soft skin, moved into place. One joined her tongue, nestling two finger-tips alongside the tip of her tongue, whilst the other curled onto Bill's stomach, arching itself so that her thumb was resting against Bill's saliva slickened clit. Before Bill could comprehend the pleasure that was about to ensue, she felt it. Two fingers and Heather's tongue plunged deep into her eager fanny, swallowing them all in her tight wetness, her hole clutching and clinging at the new wriggling intruders. Drenching Heather's fingers in her juices, Bill felt the girl's moans of pleasure reverberate through her own pussy, the taste of her juices being enough to cause a shiver of pleasure to tingle through Heather's own aroused folds.

Resting her thumb against Bill's clit, she started rubbing concentric circles across the bud, using her saliva as lubricant. The steady build of pleasure combined with the sensation of Heather's fingers slowly drilling in and out of her tight little cunt caused Bill to begin to shudder towards and orgasm. She didn't want to cum just yet but had the blissful prospect of multiple orgasms and a long night of hard, sweaty fucking. The idea spurred her on even more, her hands snaking down to Heather's blonde curled hair. Grabbing the back of Heather's head, she pushed her deeper inside her, forcing the girl's wriggling tongue even further into her spasming pussy, Heather's nose prodding her clean-shaven crotch. Moaning softly, Heather couldn't help but adore it. Silently, she always had a domination fantasy. She liked the idea of being on either side. But having someone like Bill forcing her tongue inside of her pussy, holding her head in place as she barrelled towards an orgasm was sensational. She could feel her clit twitching at the mere mention of the erotic situation.

Exploring Bill as best she could, Heather satiated herself with the delicious taste of the black girl, her pussy dripping with her slick arousal. Heather's face and cheeks quickly became as slick as Bill's pussy, if not more. Continuing to drill her fingers back and forth, Heather curled them upwards, trying her best to tickle Bill's g-spot, but finding it difficult with everything that was happening. Much to her own delight, Bill began to push her hips downwards, grinding her pussy against Heather's face, inadvertently using her nose to play with her own clit. Rolling her eyes closed, Bill lost herself in the lust of the moment, consumed by the passionate fantasies that she was living out in her head. It had been so long since she had had a good proper fuck and she was going to make the most of it in every conceivable way. Every toy she owned, every finger she had, and every ounce of energy was going to be thrust inside Heather's tight, welcoming pussy by the end of the evening.

Then she felt it. That familiar tightening in her core, the pleasurable spasms rippling through her muscles. Her orgasm hit her like a wave, and the entire apartment was filled with her delectable squeals of perverse pleasure. Her lips hung open and her chest rose and fell rapidly. Pushing her crotch downwards, she sought to squeeze every scrap of pleasure from Heather's tongue and fingers as she rode through her orgasm. Her pussy tightened exponentially, pinning Heather's fingers and tongue in place, keeping them tightly reigned inside her for maximum pleasure. Her stomach undulated, and her legs gently shook as she moaned her way through sublime bliss. She had experienced countless orgasms at her own hands, but nothing would ever beat the sheer erotic sensation of someone else pushing her over that edge. The feeling of someone else's tongue and fingers working magic between her thighs. She lost herself briefly in the swirling haze of pleasure, her hand keeping a tight grip on Heather, holding her in place until finally the twitch of pleasure ceased, and Bill flopped breathless against the bed, allowing Heather to wipe her streaky mouth and lay down beside her, tip-toeing her fingers along Bill's breasts as she caught her breath.

"Oh fuck…" Bill breathed as she stared at the ceiling. She felt as if she was overreacting a tad, but she couldn't stress how long it had been since another girl had been between her thighs doing a job as good as Heather did. That simple reaction caused Heather to blush, but for the first time that evening it was not out of nerves, but rather a perverse sense of pride and validation of her unique oral abilities.

"What can I say? Girls always do it better…" Heather smiled, circling around Bill's nipple with her finger, watching the girl's chest rise and fall. Bill turned to the blonde and stole a kiss, tasting the deliciousness of her own pussy on Heather's tongue.

"You're preaching to the choir with me. Shall I return the favour?" Bill asked, running her hand down to Heather's pussy and feeling her wetness on her digits. Playing with the puffy tuff of hair above her crotch, Bill grinned, silently wanting nothing more than to be pressed between her creamy white thighs.

"I don't know… I've shown you my forward side. Why don't you show me yours? Surprise me," Heather smirked, giggling as she began to warm to Bill. Chuckling in response, Bill thought a moment before she acted. Well, there was one thing she could do. And if she wanted to reduce Heather to nothing more a series of lustful moans and grunts, it was the way to go. She might as well make her dirty side known. It could lead to a night of pleasure beyond which she could ever imagine.

"If you say so…" Bill grinned, grabbing Heather's hips and flipping her onto her stomach. Giggling, Heather glanced behind her and watched as Bill pushed her up onto her knees, forcing the blonde to present her plump, rounded arse to her. Planting her hands firmly on Heather's ass cheeks, Bill found herself once again enthralled with the girl's rear end and had the urge to simply sit and play with her like this. However, she fought that urge and instead spread her cheeks apart, revealing the object of her perverse desire: Heather's tight, constricted arsehole, primed and ready for some good oral attention. Heather's eyes widened as she realised what was about to happen. A brief flutter of nerves came across her, but quickly she stifled them. Her interactions with women now seemed a little tame in comparison to Bill, but she was hardly going to say no. Not after feeling Bill's tongue dip into place.

That was what she felt first. The tip of Bill's tongue running gently across her asshole, fluttering into place against her tightest, untouched entrance. Running circles across her rosebud, she coated in saliva, tracing each of the tiny crevices with the tip of her tongue, forcing delicate whimpers and moans from Heather's mouth. Burying her head in the bed covers, Heather opted to close her eyes and imagined what Bill was doing as opposed to watch her. That and it helped to silence her… vocal tendencies. The dainty licks that Bill had been providing so far devolved quickly, with Bill's more perverse side taking over. Dragging her tongue back and forth across the tight hole, she lavished every inch of the girl's ass with her tongue, her hands pawing and pulling at her cheeks, playing with the handfuls of flesh like a child, all before nestling the tip of her probing, eager tongue against Heather's entrance. Heather froze, waiting for that pleasure to overwhelm her; waiting.

She felt the slow build of pressure begin to push against her asshole, her tight entrance almost unwilling to give away to the pushing force of Bill's tongue. Bill kept it. She knew from experience that it took some effort and Heather was willing to wait it out. Searching for the right angle, Bill eventually found It, wriggling the very tip of her tongue inside of Heather's asshole and opening her up just enough for the rest to follow. Her eager fondling of Heather's ass turned to a gently massage, one of her hands going down to her pussy and finding her clit, all in an attempt to relax her as her ass wanted penetrated. It took a little work, but slowly and surely, Bill's tongue began to carve a sumptuous path into Heather's waiting rear, plunging deeper and deeper into her untouched hole. Heather's muffled moans, grunts and groans became increasingly audible, even when smothered amongst the covers of the bed and eventually those sounds of pleasure turned a squeal of one.

Her body tightened as Bill pushed the last bit of her tongue inside of Heather's ass, her wriggling muscle exploring the girl's tightness, gently working to loosen her up. Heather pushed back onto Bill's tongue, wanting to go deeper; wanting to have Bill submerged even further. Feeling the blonde's eagerness, Bill made her next move. It was a little soon, but Bill knew Heather wanted it. Taking her finger, she ran it through Heather's pussy, drenching it in her arousal and pulling it away, dripping in her juices. Or in other words, lubricated. Lifting it to Heather's asshole, Bill made some room next to her tongue and with a little work, managed to worm the tip of her finger past her constricted entrance. Breathing sharply inwards, Heather felt a spark of pain as her tight ring was stretched that little bit further, however, that pain was quickly mitigated by the pleasure of having said finger plunge deeper inside her. The main avenue of pleasure came from the sensation of fullness. There were never many nerve endings inside her ass, but that sensation of something simply sitting up her ass was enough to drive her wild. The idea of a butt-plug suddenly made sense in the young slut's mind and her pussy began to quiver even more. The pleasure was only accentuated by Bill's tongue which ensured she remained lubricated and also explored further and deeper, loosening her up for more.

Before she could grow used to the sensation, Heather felt Bill's tongue begin to move back and forth alongside her finger, the two of them slowly drilling back and forth, pumping deeper into her ass. Her other hand slipped between the blonde's thighs, finding her dripping wet pussy and immediately attacking her delicate clit, overwhelming her lithe body with tingling bursts of pleasure. Moaning and squealing loudly, Heather continued to push herself back onto Bill's probing digits, gently fucking herself against the coloured girl. Her mind was swarmed with pleasure and the feverish ministrations of Bill's skilful tongue. It was surprising to say the least. Heather was hardly the kind of girl to do this stuff and yet she had lucked out and found a girl with adept tongue skills, perverse lack of inhibition and a hungry desire to make her cum.

On the verge of her orgasm, Heather planted her head in the pillow, slipping her own hand between her legs. Brushing Bill's aside, she took the place of her fingers, furiously rubbing her clit as Bill's hands were forced elsewhere. Quickly adapting, Bill slipped two fingers inside the blonde. Feeling Heather's warm drenching her fingers was engrossing, and Bill felt the urge to taste the young girl building on her lips. Her perverse sensibilities took over (and combined with her lust for more pleasure), prompting Bill to grab Heather's hips and roll her over. Flopping flat on her back, Heather looked up, confused, only to be met with a far more enticing sight than she could have imagined. A single giggle escaped her lips before the sound was muffled beneath handfuls of soft, delicious flesh.

Straddling Heather's face, Bill didn't bother waiting a moment before sinking her hips down and smothering the blonde between her arousal slickened thighs and sopping wet folds. Feeling Heather's lips pressed once more against her pussy, she moaned, gently squeezing Heather's breasts as she savoured the familiar sensation. However, her feverish passion was quickly met by the blonde as she lifted her legs and wrapped them around Bill's neck, pulling the coloured girl down between her thighs and tightly forcing her lips against her own creamy pussy. Unable to deny herself the luxury, Bill plunged her tongue inside of the girl, spurred on by the blonde's retaliation. For each moan that escaped her own mouth, it seemed she plucked several more from Heather's, those moans then reverberating through her own folds and pushing herself to moan. A constant perverse cycle of limitless sexual pleasure; a divine thing indeed. The mere thought was enough to make Bill shiver with anticipation.

However, she didn't have to anticipate anything as she and Heather quickly swept each other away into their own fantasy. Emboldened by Bill's pep-talk and the promise of an orgasm, Heather became somewhat forward and bold. Her hands lifted suddenly and came crashing down on Bill's bum cheeks, the sharp stinging sensation causing Bill to squeal. The burn set Bill on fire, with the stinging marks left on her flesh only amplifying the pleasure building in her body. She wasn't averse to a good spanking every now and again and was a little embarrassed about the fact that tucked away in the back of her wardrobe (beside her other explicit items) was a rather brusque leather paddle; a relic from a previous kinky relationship.

She felt Heather spank her again and again, her slaps always timed with the tightening of her lips around her clit, or the deeper plunging of her tongue. Continuing to devour Heather's pussy, Bill quickly became a little disappointed, as after a while, the spanking stopped, and Heather's fingers disappeared. It was only moments later that she realised where her digits had been. Heather had dipped them down to Bill's pussy, drenching them in her juices before endeavouring the return the favour. It took Bill a moment, but she felt those slick finger-tips pressed up against her rear entrance, and she couldn't help but bite her lip in anticipation. Bill wasn't an anal slut. She was… an experimenter. She liked the kinky stuff and the rough stuff because she liked to put herself out there. It wasn't that having fingers up her ass was more pleasurable than inside her pussy, but it was more satisfying for her adventurous side. After all, if she was going to forgo cock, she was going to make the most of everything a woman's body could offer. Pussy, tits and ass included. Although, she was a little ashamed at how easily Heather pushed inside her.

Two of her finger tips eased inside of Bill's asshole without even a second thought, with Bill almost pulling them deeper inside of her. The groan that escaped her lips however sent immeasurably pleasurable vibrations through Heather's pussy, all but ensuring that the blonde was going to exploit the affiliation Bill had with anal. Pushing easily forwards, Heather sank her digits right up to the knuckle inside her tight hole, causing Bill to lift her lips away from her pussy, moaning loudly through the house. Were her foster mother in, the racket would be incredibly incriminating, however Bill was confidant in screaming the flat down. The sensation was intense and entirely worth it. Gently fucking her tightest entrance, Heather watched the girl arch her back, pushing her pussy further down on Heather's face, Bill selfishly abandoning the pursuit of Heather's orgasm.

That didn't stop Heather, especially considering she could feel Bill tightening once more, her body about to shudder into a second orgasm. Attacking her sweet spots yet again, Heather was bold enough to slip a third finger inside of Bill's ass, causing Bill to go silent, her moans becoming hollow as she simply parted her lips and breathed heavy. Her body began to twitch and shudder into that familiar position and before long she let out an intense, lustful moan, her body quivering for a few moments before rolling to one side. Heather grinned as she crawled beside Bill's breathless, sweaty both and tenderly wrapped her lips around Bill's nipple, gently biting into her flesh as Bill looked towards her apologetically. Heather broke the silence, "I hope you don't mind me saying, you didn't really manage to return the favour…"

"I'm sorry… It's just… Well, I'm sensitive back there… And well… Well, you saw…" Bill smiled, watching Heather's dainty, pursed lips nibble at her sumptuous flesh, leaving bright hickey marks on her dark, chocolaty skin, steaks of shimmering saliva causing them to glisten.

"For what it's worth. I was really very close. Won't take much to finish the job. A few licks here, a few licks there…" Heather suggested, her forwardness derived from the necessity her body felt to get that sweet relief. Leaning back slightly, she flaunted her glistening pussy.

"After I've had two, you deserve something special. A few licks ain't going to cut it. Especially for my self-esteem…" Bill smirked, sneaking a quick kiss from Heather before rolling off the bed, her ass and tits gently jiggling as wandered over to her wardrobe. Heather reclined, spreading her legs as she ogled Bill's delicious body from a distance, admiring the way her flesh sparkled with sweat and arousal, her body even more enticing than before. Playing with herself, she caught Bill's attention for a moment, "Don't you even think about finishing yourself off."

"Wouldn't dream of it…" Heather chirped, casually rubbing herself as Bill rummaged around in the back of her wardrobe. Pushing aside a heap of her clothes, she loosened the panel at the back before plucking from a hidden compartment the object of her desire. If her foster-mother found these, she'd have an aneurism. Smiling as she held it in her hand, she closed the cupboard and held it up in front of Heather, receiving nothing but a confused look, "What is that? No… That's not a…"

"Oh yes, it is… What did you say earlier? Girls do it better? Well this… This is Exhibit A in that case," Bill smirked, untangling the mess of straps and slipping it over her feet. Tugging it up into place, she fastened the straps in place, tightening the harness and making sure it framed her ass just right, the fabric dipping between her pert ass cheeks. After adjusting the ridge patch of plastic on the inside to press against her clit, she stood proudly in-front of Heather, sporting a thick nine-inches of rigid black cock, taped and modelled in all the right ways, with pronounced details and immensely pleasurable ridges.

"I've never… Well, I mean never seen one before… Let alone a real, well, real cock. This is… Can I tou…" Heather said nervously as Bill strode over to the edge of the bed. Tentatively reaching her fingers out, Heather wrapped them around the plastic length, gently squeezing it and running it along her palm. It was bizarre. She could swear it was throbbing in her hand. She looked up and caught Bill's gaze, seeing her smirk as she fondled and stroked the fake cock as if it was real. Seeing the flicker of judgement on Bill's face, Heather replaced her uncertainty to reaffirmed eagerness. Bill wanted forwards, she'd get forwards.

Whilst it did nothing for pleasure, Heather still wrapped her lips tightly around the long, thick cock, sliding them down until she began to gag on the ridged plastic. Keeping her eyes latched on Bill's, she saw a smile of approval stretch across her lips as the blonde forced herself to gag and splutter around the shaft. It didn't do much, but the little movement that she was sending through the cock caused the ribbed plastic inlay on the strap-on to grind against Bill's swollen clit, her body getting brief glimpses of pleasure Heather's blowjob. Whilst Bill was never one for cocks, she has a special affinity for those attached to women. She couldn't quite explain it as she would be completely uninterested if someone was sucking a real one, but seeing Heather greedily guzzling on her fake one was immensely satisfying; purely for perverse reasoning.

Reaching around behind Bill, Heather grabbed her ass cheeks, pulling her further forwards and pushing the tip of the cock up against her throat. Swallowing deeply, Heather spluttered wildly as the rest of the shaft pushed inside, her lips wrapped tightly around the base of the shaft. Saliva spilled along the shaft, coating it liberally, all the while beginning to drip along her chin. Were Bill a man, the pleasure coursing through that cock would be indescribable as Heather's throat convulsed and spasmed in the most delicious way. Pulling her lips back, she breathed a deep breath, jerking the slopping, saliva-streaked cock in her hand before looking up at Bill expectantly, "Well? Aren't you going to fuck me?"
"There she is…" Bill grinned as Heather rolled onto all fours, arching her back and pushing her plump, delicious arse into the air. Unable to resist the allure, Bill returned the favour from earlier and spanked the blonde's milky cheeks sharply. Gasping, Heather did nothing but wiggle her bum in approval, Bill's hand-prints burning a hot red on her skin, leaving a mark. Slapping the black cock in between Heather's cheeks, Bill grabbed her hips and began to draw the shaft back and forth, lazily fucking the young girl's butt, the plastic running up against her asshole, threatening entry to her tight, recently-explored rear. Moaning in anticipation, Heather bit her lip, waiting for the moment when Bill redirected the thrusting tip of her bulbous strap-on into her tight, clutching pussy. Being on the brink of her orgasm didn't help the urge to simply stop with the teasing and impale herself, but she waited, each thrust adding the building lust between her legs. Her thighs were slick and her pussy sensitive. And in one swift blow, she was rendered silent; silent with near-orgasmic pleasure.

Grabbing the base of the strap-on, Bill slipped it slightly lower, letting the tip graze over Heather's asshole before finding its way between her thighs and towards her pussy. Guiding the head past her folds, Bill made sure that it pierced her properly, sinking half the length of the shaft inside Heather's tight, ready pussy before returning her hands to her hips. Pulling Heather's ass back onto her thrust, Bill slammed every inch inside her cunt, causing Heather's lips to part, and only her ragged breath to fill the room. Waiting for a moment, Bill let the blonde adjust to the new intruder; an intruder which probed depths she didn't even know she had. Finally, a moan escaped Heather's lips and she pushed her bum back onto Bill's crotch, trying to squeeze a little more depth of the pleasurable length.

Grinning, Bill took a firm grip of Heather's hips and slowly began to thrust back and forth, filling the room with the delicious, wet slapping of flesh, their bodies colliding again and again. Bill became entranced with the shockwaves that rippled through Heather's ass with each thrust, her eyes watching the flesh jiggle time and time again as she lengthened her stroke. Pulling more cock out and slamming even more back in, she quickly built her rhythm, with each thrust being met by Heather, who happily bounce back and forth on the cock, impaling herself gleefully as she searched for that ever-elusive orgasm. She could feel it bubbling in her belly, threatening to come to the surface with each passing thrust. Moaning like some common whore, Heather glanced over her shoulder, watching Bill as she fucked her; the way her lips parted, the soft bounce to her chest, and the constantly moving slab of cock she was sporting. Before tonight, she never entertained the idea of using a strap-on. Now? She wanted a collection.

And then the slapping of flesh and the constant moans was broken by the sharp spanking of flesh. Bill, her eyes now locked with Heather's, lifted her hands and sharply spanked her cheeks, watching as the red marks rose in her flesh. Holding off on another sharp spank, Bill watched Heather bite her lip, her eyes growing softer, her demeanour shifting… submitting. Groaning in satisfaction, Bill quickened the pace, pounding and hammering into Heather's quivering little pussy, drilling her virgin quim like it was her own, pulling their bodies passionately together. The room smelt like sex, their bodies glistening lightly with sweat and their pussy dripping with arousal. Losing her breath from her sudden spirited burst, Bill let Heather take the reins, her brief stint of submission replaced by her forward demeanour.

Throwing Bill onto her back, Heather straddled her hips, readjusting herself and easing herself down Bill's cock in a slow and sensual manner. With her pussy resting against Bill's crotch, Heather grabbed the coloured girl's breasts, gently squeezing them as she rose up and down, dropping herself down and onto Bill's fake cock. Moans filled the room once more as their passionate romp devolved into a slow and sensual embrace. Bill's hands rose to her hips, gently guiding the blonde up and down as she bounced softly on her cock, only every sliding a couple inches in and out of herself. Her orgasm was on the verge of washing over her and she wanted to savour every embrace. Whilst she knew that the promise of many more orgasms was on the table, she wanted to make this moment count. Her slowly riding Bill, echoed by the occasional slap of flesh. It seemed a fitting end to the beginning of a night.

Leaning forwards, Heather planted her lips against Bill's pulling her into a deep and passionate kiss, their tongue intertwining, neither one seeking to dominate the other, but simply seeking pleasure. Their hands explored each other's bodies as Heather continued riding herself into bliss. Continuing to tweak Bill's nipples, Heather moaned into Bill's lips as the coloured girl's hands found her arse, her fingers running themselves along her asshole. Whilst she wasn't fully committed to the rigorous exploration of her tightest hole, Heather had certainly been won over a little by Bill's probing digits. There was nothing wrong with a cheeky finger up the arse in her book. And Bill didn't disappoint, wriggling the tip of her index finger past Heather's tight asshole and snaking it as deep as she possibly could. That was the lynch pin in setting Heather off.

Her orgasm hit and hit her hard. Despite the slow and sensual nature of their fuck, the preceding pleasure meant that her orgasm was intense. Pulling her lips away from Bill's, Heather's breath quickened, the pitch of her moans heightening as she slowed her gentle riding. Squealing loud and sharply, Heather made sure that even the neighbours knew she was cumming, all to the veritable glee of Bill, who pushed her further along, with her fingers pinching and squeezing her pink nipples. After several long and pleasurable seconds, Heather rolled to one side to catch her breath, resting in the nook of Bill's arm as Bill's hand lazily jerked her strap-on off, coating her palm in Heather's sweet, sweet juices.

"You're a screamer?" Bill grinned as Heather playfully slapped her on ass, scoffing as the two of them lay there giggling, their bodies pulling one another closer. With a smile on her face, Heather kissed Bill again, their tongue returning to their playful battle dynamic.

"You're not one to talk…" Heather smirked, pulling away, the two of them simply laying there for a moment. Silence claimed the two of them as they lay together in bed, their arms snaked around one another, their sweaty orgasm-ridden bodies pressed together. Minutes passed, the two of them gazing listlessly of into space, until Heather turned to Bill and with a wry grin asked, "I don't suppose I could have a shot? Wearing it, that is?"

Author's Note: Hope you enjoyed that. It was a commission that I did a while back and one I thoroughly enjoyed. Whilst I enjoyed Bill as a character, I didn't find much of an excuse to write a story solely focussing on her, hence, she will be a large part of this story. After all, surely the first thing a female Doctor would do is go back in time and get with the one companion she never had a chance with. It's what I'd do…

So, the next chapter. Well, there isn't really much point in me teasing it, considering that… well, it's already posted. But, the Doctor, in her new female form, decides that she isn't quite ready to face the world of lesbian sex and definitely doesn't want to explore the world of straight sex. So, when she secures her Tardis, she nips back in time to visit a few olds friends who are more than happy to teach her how it all works.
