A/N: This was a challenge of sorts. I want to manage some expectations here: This is 2000-ish words of our favorite shape-shifter Lucy eating Gwen's ass while Gwen dominates her. That's it. If that ain't your thing, this is your only warning.
"Ah, Lucy! Gwen said you were coming." Natalie smiled at the blonde, beckoning her inside, and Lucy fought the urge to courtesy her dress as she stepped over the threshold. Gwen's mother always inspired a certain sense of propriety in her- as did Gwen, really. But with Gwen, Lucy relished in breaking through it. She enjoyed being irreverent and flirtatious with the younger redhead, out of spite, genuine attraction and just good fun.
She didn't think to do so with Natalie, even if Lucy couldn't quite resist lowering her eyes to the woman's skirt clad rear when she was led into the house. A simple pencil skirt it may be, but Gwen didn't get her hips from a stranger. Lucy bit her lips, wrenching her eyes away from the delectable sight.
Gwen had been very... assertive about some boundaries that the blonde was not to cross- and aunt Nat, as her and Ben consistently called her despite the actual relation being more complicated, was one of them. She would not assess the older woman. She would not blaspheme her by mentioning her finer points out loud. She would not make any move on her.
Not when Gwen had what Lucy craved and was perfectly willing to withhold it if the blonde stepped out of line.
"There you are!" A voice drifted down from above, seconds before Gwen came into view, descending to halfway down the stairs. She was clad in simple white pants and a baby blue hoodie. Something about those clothes seemed off to Lucy, but she couldn't quite put her finger on it. Especially when the sweetness of Gwen's cheerful, welcoming smile was undercut by a knowing glint in her eyes. Lucy swallowed.
Gwen had caught her looking at Natalie. That might come back to bite Lucy later. Or it wouldn't, if she preformed well enough. Or it would anyway, just on a whim. Gwen was unpredictable like that, for all that she was consistent as clockwork anywhere else.
And that excited her all the more. Gwen slid her gaze away and over to her mother, addressing the woman. "I think we can share my thermos- do you mind if I take her up? We have a lot of ground to cover. Biology might be our favorite subject, it's still a lot."
"Oh, that's fine. As long as she comes over sometime for brunch." Nathalie waved her daughter off, good-naturedly, oblivious to the way Lucy's core clenched at the redheads words.
Turning her gaze back to Lucy, Gwen jerked her head up, delicately. "Come on."
Lucy was more than happy to follow behind Gwen up the stairs, and as soon as Nathalie turned away and moved back into the depths of the house, Gwen also didn't bother to hide the extra sway she gave her steps. Lucy bit her lips, but made no comment, made no moves where she normally would despite the rolling hips all but begging her to.
Not at this game. If she did, Gwen might deny her. And Lucy had gone for three days without. She would not take well to another drought.
Before she knew it, Gwen opened the door to her room and went through, telling Lucy to shut it behind her. Lucy did, and when the door clicked shut, Gwen smiled at the blonde over her shoulders, a sly slant of lips that told Lucy she would not have to beg tonight.
Sometimes, Gwen would make her. She'd pour herself a cup of tea, sit on the bed and just continue with homework, roping Lucy into it (if anything, the reason Lucy's grades had been rising was because she had ample motivation to do her homework well on those nights).
And other times she would just wait, not even dignifying Lucy squirming and thirst till she begged Gwen.
But tonight, neither was the case. Gwen snapped her fingers, a spark of blue between them shining for a brief second and a pulse of magic shot out from her, coloring runes all over the floor, walls and ceiling until they reached the door. Lucy shuddered when it passed over her skin. A silencing spell, to muffle any sounds coming from the room, and a suggestion spell on the door, to dissuade any would be interlopers. There would be no interruptions.
And the pulse also revealed why Lucy had felt the clothes on Gwen looked strange, for they disappeared as if vaporized, the illusion lifting.
Lucy swallowed, mouth dry at the sight of Gwen's sensual curves, of her round, firm cheeks that trembled just slightly with every slow step she took towards the bed. The thought that Gwen had been naked the entire time added a perspective that made Lucy wet her lips in anticipation.
Gwen, for her part, took mercy on Lucy. She sprawled out on her front, legs spread, her upper body supported on her elbows, looking back at Lucy over her shoulders. It left plenty of space for Lucy to get behind her, if she was allowed.
And she was. "Strip, and come here." Lucy hadn't bothered with actual clothing, merely shifting her form to one of nudity, the sensations of her 'skin' becoming distinctly different as she did.
Lucy wasted no time crawling onto Gwen's bed, laying herself on her front so that her head hovered over those perfect globes, and she could not resist burying her face into them, inhaling deeply, letting the other girl's warmth and scent wash over her. Gwen seemed to be in a merciful mood, because she made no comment other than a slight hitch in her breath and an appreciative hum.
But for all that Gwen allowed some things, Lucy knew she had to ask permission at least once. "Please," she rasped, running her lips over Gwen's cheeks as she did, unable to resist a single long lick up and down the crack between them. The taste went straight from her tongue to her core. "please." She emphasized. "Let me-"
A hand fisted in her blonde hair and for a second she feared Gwen was going to tear her away for daring to lick, but instead her head was forced down firmly, aligning her mouth with Gwen's anus.
"Get to it, you filthy addict." Gwen commanded, haughtily, and Lucy moaned straight into her cheeks before she stuck out her tongue and got to work, resting her hands on Gwen's ass cheeks to pull them wide- relishing in groping the luscious globes as she did.
The taste was clean as could be, as Lucy had known in advance. Gwen didn't have to keep it that pristine- Lucy could just as easily turn the taste buds on her tongue off. Heck, she could shift her tongue to be a giant clitoris, if she concentrated hard enough.
But the fact that Gwen was willing to make this tasty for Lucy, really got her going. And as much as the sensation of poking a clit-tongue into Gwen's ass sounded interesting...
Lucy moaned, muffled, burying her tongue deeper, nails digging into Gwen's cheeks ever so slightly. She got a moan of approval in return.
Yes, as interesting as that would be, the very fact that Lucy could get this much pleasure from just tasting Gwen's ass said infinitely more about how depraved Lucy, and Gwen, really were, and that got her going far better than any tongue orgasm ever could.
She trailed her tongue along the rim, wetting it and stretching it with both hand and tongue, and before long, it was relaxed, wide and so, so tasty.
And so ready.
The hand in her hair retreated, there was no further need for it. Lucy wouldn't move for the world, spellbound, and to demonstrate this she buried her face even deeper, finally allowing her tongue to enter Gwen's ass beyond just the tip.
"Yessss." Gwen groaned and Lucy groaned her own agreement.
Gwen's flavor washed over her and she gasped, trying to get as deep as she could like this. She could go deeper whenever if she shape-shifted her tongue, but she would wait for permission. For now, she just kneaded Gwen's cheek, and opened her eyes.
She trailed her eyes passed Gwen's ass, up the sinewy line of her spine, following the flowing curves of her body till it landed on red hair. As if feeling her gaze, Gwen turned her head, meeting Lucy's pleading lavender with sharp, lust addled green.
'Please.' She silently begged, curling her tongue in lieu of saying the word, her lips greedily working around the rim, trying to get as much in her mouth as she could. Gwen's lips curled and she reached back, running a hand over Lucy's hair teasingly. But she didn't give permission yet. Lucy again curled her tongue, watching Gwen's eyes lose focus for a second as she shuddered, before her gaze zeroed in on Lucy again. The redhead gave her a single nod and Lucy inwardly cheered, flicking her tongue as a silent 'Thank you!' before she got to work properly.
And then her tongue started to stretch deeper and Gwen gasped, her body convulsing. Lucy kept her steady as she did, hands firmly placed on the girl's ass cheeks, her arms bracketing Gwen's thighs. But for all that she held the cards, the Lenopan was conditioned well.
So instead of gloating, smirking, or even teasing with what few means she had available to her, she just stretched her tongue deeper, appreciating that Gwen always prepared for these meetings with a bona fide bowel cleanse.
Mostly because it spoke volumes on how much the redhead enjoyed Lucy coming over for a meal. And Lucy had always been a sucker for validation.
Pulling her lips slightly off Gwen's rim, Lucy used the added space to allow her tongue to pull slightly back out of Gwen- only to thrust it back in with a sharp motion. Gwen, for her part, moaned her approval heatedly. "That's it." She breathed.
The redhead raised her hips slightly, her knees curling and her feet rising slightly into the air so she could properly push back against Lucy's thrusting tongue. And by fuck if that wasn't Lucy's literal favorite thing in the world.
"D-Deeper." Gwen commanded, voice breathy, her skin flushing, her ass cheeks quivering, spine glistening with sweat and Lucy obeyed, pushing deeper into Gwen, going deeper than even the largest cock could have reached- and then pushing further.
Gwen moaned, loudly, her position shifting till the girl was no longer lying down but on all fours, her upper body still supported on her forearms and elbows. For all that it was a submissive position, Lucy was the subject here- the devotee worshiping at the altar.
And worship Lucy did. She worshiped the way Gwen's back curved down, propping up her hips; she worshiped the perfect ass in her hands, spread wide and so, so amazing; she worshiped the way that thighs quivered with every thrust of Lucy's tongue, the taste assaulting her senses, the delirium inducing smell of Gwen's sweat coming into her nose, all the more so when Lucy once again closed the distance with Gwen's rim, forgoing thrusts in favor of thrashing her tongue around inside erratically, to the heated approving gasps of Gwen, clutching the sheets tightly.
And it all came to a crescendo when Gwen cried out in a long, drawn out moan, her body convulsing around Lucy's tongue, her fingers clenching in the sheets as she fell forward- Lucy following easily- and wrapped her legs around Lucy's head when she landed, loathe to let the blonde escape from the prison of her most intimate parts.
And Lucy was a willing prisoner, because rather than even attempt to escape she burrowed deeper into her cell, thrashing her tongue, her lips, her hands, everything she could, in an effort to just keep going, keep the girl coming, keep her mistress sated.
Gwen's orgasm lasted what felt like forever, and by the time it was done, Lucy's head was squeezed so hard that if she'd been human, she'd have bruises to show for it. As it was, she was lightheaded, nigh mad with intoxication, and unrelenting in her devotion, refusing to stop until told.
Through the haze of her own pleasure, she could only continue thrusting her tongue, slowly pulling it back, slowly, slowly, until it reached it's regular size and could only touch the closest reaches of Gwen's anal cavity.
Then Gwen's legs relaxed, a sigh passing the redhead's lips, the sound distant over the roaring in Lucy's ears, and the blonde pulled out of her lover's ass entirely, pulling her tongue back into her mouth and savoring it there, gasping for breath.
It took a while, but eventually she felt Gwen's hand tangle in her blonde locks again- a soothing run of fingers rather than anything demanding, and she forced her eyes open to look passed the ravaged pucker of Gwen's ass, passed her cheeks and up her spine to see the redhead looking down at her over her shoulder again, green eyes warm.
"Well done, Lucy."
All Lucy could offer in return was a moan. "Y-You're so welcome, mistress."
It was not a term of endearment that Gwen enjoyed, generally, but she seemed to have done a good job. It was allowed.
But clearly, Gwen still had some whims in her. Her smile sharpened. "I saw you looking. Downstairs." The girl told Lucy, to the blonde's confusion. If Gwen was going to punish her for that, she would have already done so-
Gwen pushed her hips up, her legs tightening around Lucy's head again, not nearly the clench it had been, but a clear signal. The blonde's eyes widened, her core clenching in excitement again even as her heart skipped several beats. Gwen only smirked.
"Get ready for round two, rule breaker."
Lucy could only moan, before diving back in with nary a pause for breath. Because Gwen wasn't wrong.
She really was an addict.
