Once upon a time long past, their relationship could have stayed professional. And oh, how quickly things changed between them. It was difficult even for Saria to gauge exactly when their disposition towards one another had changed so dramatically.

As the Doctor sat back in his office chair and groaned with pleasure, Saria didn't seem so sure. No, she thought, it must have been during one of her rare vulnerable moments. A confession of just how much she'd missed belonging to someone else.

The Doctor understood her. He felt the same as she had. That longing for another. They'd come from shaky relationships that left them feeling lesser. As a unit, they could become stronger together. Heal each other.

That's what this was, she thought. Healing… in her own special way. The sensation of his fingers in her hair was simply divine. It made her feel smaller than she was, and she enjoyed feeling smaller if it was all for him. It was a refreshing change of pace. Those soft and lingering touches, those points of affection, she lived for them. She grew to expect them, like rewards for splendid work. Praises following a job well done. For example, a blow job well done.

She took him further into her mouth, settling comfortably beneath his work desk and fellating him with all the vim and vigor that she usually gave him when she serviced him like this. He felt so filling in her mouth, and she moaned around his cock from the splendor and the sensation alone. He tasted wonderful; his shaft was hot and heavy on her tongue while she moved her head in and out, back and forth at his crotch.

Another moan slipped from the Doctor's mouth. He rested his head on his desk, beneath which Saria continued to run her tongue along the length of his dick. She was a tall and burly woman; it was frankly an engineering miracle she could fit so comfortably beneath the man's workstation as she did so often.

"Fuck," The Doctor moaned, squirming with pleasure and delight as his dearest assistant served him well. Saria's willingness to get down on her knees for him still surprised him, if only a little. The woman had a penchant for oral pleasure, and it was a penchant that the Doctor of Rhodes Island was always keen on utilizing.

Down here, she could play with his shaft as much as she wanted. She could take him all the way down. Welcome him home into her hot and wet maw. Underneath his desk like this, she could also bask in the aroma of his manly musk and let it further fuel her. Let it spur her on, like the workhorse she was.

"God, that mouth of yours…" The Doctor trailed off, the pleasure spreading out from his core and stopping his train of thought. Saria smirked as she blew him; she loved the high praises that the Doctor sang for her during their more intimate moments. She almost felt bad that no one else was around to witness this depravity. The ex-director of Rhine Lab's defense division, on her knees for the Doctor of Rhodes Island… and she was loving every second.

Saria could tell that he was close. Very close. She double-timed it, moving her head up and down as she fellated him, nuzzling his hand and urging him to go faster. Deeper. Deeper.

It wasn't much longer before the Doctor reached his climax, and he gripped a clump of Saria's hair as she suddenly felt the inside of her mouth splattered with hot, wet spunk. She moaned as she drank it down — as soon as her lover's essence splashed against her teeth, gums, and tongue, she greedily gulped it down. As much as she could swallow, for there was nothing she couldn't take that he gave her. She could handle anything that he threw her way or shot down her throat.

Gulp… gulp… gulp…

The Doctor's moaning spurred her to keep going. To not stop sucking him until he had finished blasting ropes down her throat, and only when it finally stopped coming did the Doctor pull back with a grateful sigh, his cock slipping out of Saria's mouth so that she could pepper it with loving, thankful kisses.

"Ha… I bet you're feeling much more relaxed now, Doctor…"

With what little room Saria had for her tail, it wiggled joyfully as the Doctor once again pat her over the head.

"Fuck, Saria…" The Doctor once again sighed relaxedly. "That was… wow…"

The Vouivre smacked her lips as if she had just sampled something delicious and satisfying. She truly thought she had. Still, beneath the table, Saria leaned in and nuzzled the Doctor's leg, letting hot air pass through her lips.

"So, you've changed your diet?" Saria hummed appreciatively. "That, or I've grown to love the way you taste…"

"Perhaps both," the Doctor told her, scooting back in his rolling chair so Saria could come out from under his desk. As much as she loved being under there, she conceded it would probably be for the best if she got some stretching done. In a moment, she was standing beside his desk and doing just that, raising her arms above her head and cracking her neck.

"Well, perhaps now you could focus on those assignments," Saria offered, smiling slyly at her Doctor as she leaned up against his workstation. The Vouivre assistant — who stood taller than the Doctor himself — ran a hand through her own silver locks in a moment of adjustment. The Doctor chuckled, casting a glance at the many documents and proposals piled on his desk. His intention first was to spread them over his desk and pound right through them. However, it was Saria that the Doctor wanted to spread over his desk and pound.

"You're thinking about something inappropriate again," Saria noted aloud. The Doctor cleared his throat.

"Not at all," he lied.

"Are you lying to me?"

"Nope." There was another!

"Mm…" Saria looked back at the Doctor's office door, thankful that it was locked. She couldn't deny it: she was thinking filthy thoughts, too. That blow job had left her feeling wanting, and while the Doctor would happily oblige her for her own pleasure… today, Saria wanted to try something new. Something new and enticing. Something delicious.

"Doctor…" Saria whispered.

"Yes?" He immediately perked up. "You want to take things further, right?"

Saria nodded silently. Her sudden meekness surprised the Doctor. He noted how she avoided direct eye contact, and she wrung her hands together as if she were trying to find the right words to use. Honestly, the Doctor thought that seeing Saria in this context was wicked cute. It seemed like only yesterday she had served as the bulwark between Rhine Lab's business rivals and Rhodes Island proper. She could fight just as well as Rhodes' own elite operators and special task force. With intimacy, however, Saria would sometimes clam up, needing to be coaxed out of that diamond-hard shell.

"I want to try something new," she told him, finally meeting his gaze with one of her own.

"Oh?"

"Mm-hmm." Saria huffed. "Why don't we try switching our roles for a change?"

"Switching our roles?" The Doctor was flabbergasted. "You mean…"

"Yes, Doctor. Are you really going to make me say it?" Saria blushed, her cheeks turning red as the words tumbled out of her mouth. "I want to be the submissive one for a change. For the entire thing," she clarified, "and I'd like to try using some… binds, if that's okay with you…"

"Of course, it's okay with me!" Saria's lover was thoroughly excited now. The Doctor never once suspected that his Saria — one of his closest confidants and his sexual partner — would have wanted to try mixing things up like this. Given how much bigger and taller she was than him, he had always assumed that she would play the more dominant role between them, and he didn't mind that one bit.

Still, the thought of dominating Saria… THE Saria…

Even though he'd just reached his climax, the thought of climbing that mountain was deeply arousing to him. The Doctor chuckled behind his mask, and he laid Saria's worries to rest.

"I would love to try that with you," he told her, watching the wyvern's face light up at the news.

"That's wonderful, Doctor…" Saria smiled confidently. "We should discuss it right now."

"Why not?" The Doctor shrugged easily. "Might as well keep neglecting my duties while you're here."

"Ah, maybe I'm being a bad influence on you," Saria muttered. "Dr. Kal'tsit may be upset."

"She's always upset. Don't worry about it!" The Doctor waved dismissively. "Let's talk more about dominating you!"

"D-Doctor…" Saria crossed her arms and looked down at the floor. "You really shouldn't say that so loudly…"

The plan was simple enough: the two lovers would consider this a test run; they would check for the boundaries of their role reversal to glean what worked and what didn't. To say that Saria was excited, however, would be a gross understatement.

"I've got a few things for us to experiment with," the Doctor told her, immediately piquing the wyvern's attention and prompting her to ask what they would try first. "First, I think it's important to make sure that we're both on the same page the entire time. We need a safe word," he said.

"A safe word?" Saria tapped her forefinger against her chin. "Something we wouldn't normally say in speech, or while swept up in all the passion…"

"Indeed…" The Doctor mimicked his lover, tapping his finger against the side of his head while he thought of what could be said.

In the end, they decided that their safe word was Kal'tsit. It was perfect. You said Kal'tsit when the fun times were over.

"I have to ask, what made you decide to try this?" The Doctor looked up at Saria as he gave his inquiry, and Saria already knew how to answer his question. She did so posthaste, without a lick of hesitation on her part.

"Whenever I wrap my lips around you and service you in how I do," she told him, "it makes me feel smaller than I really am. I really like that feeling. It's very relaxing and very relieving for me. I want to feel more of that smallness," she told him. "I would love it if you could help me feel that way, Doctor…"

Just then, and without saying a word, the Doctor reached out and wrapped his arms around Saria's bulky form, holding her as though he could squeeze all her troubles away. Saria stiffened for a moment — but only for a moment — before she allowed herself to melt into his arms, and she held him closely, tenderly, and with all the passion that she could muster.

"Alright, Doctor…" Saria rubbed his back, careful not to hurt him with her strength. "I want you to dominate me. I want you to show me what being… a bottom… feels like." She cleared her throat, pulling back to put her hands on his shoulders, and she looked at him with paramount resolution. "Please, Doctor! Tie me up and have your way with me…!"

"Pfft." The Doctor could only give a sly smile. "Now you're the one being loud…"

"You could gag me," Saria offered, smiling bashfully as she made her offer.

"But if I do that," said the Doctor, "then how will you use our safe word?"

"I'll strike you with my tail to get your attention."

He winced. "Gently, I hope…!"

With one last tug, the Doctor fondly regarded the taut ropes that kept Saria's legs bound and spread atop his desk. He knew no one would interrupt them. He was going to be working only on Saria for quite some time.

"Ready?" He asked her, as he held the gag up to her mouth.

"Do it, Doctor," Saria told him, before parting her lips with a pleasing smile. She welcomed the gag into her mouth and sealed her lips as best she could, thoroughly silenced but for the inevitable groans, moans, and whimpers.

With that done, the Doctor brought his attention to Saria's naked body, bringing his hands to her inner thighs so that he could rub and caress them to get things heating up. Saria started squirming almost immediately, her eyes drifting closed as she moaned through her gag and her entire body trembled just from her sexual partner's touch. She could barely move, and that's exactly what she wanted.

"I don't tell you this enough," the Doctor whispered, "but I love your body…"

Saria opened her eyes again, and she blushed at the Doctor's words. She knew he adored her form, of course — their size difference was a marvel all its own — but she always loved listening to him wax poetic about her body.

"You're so fucking hot," the Doctor praised, sliding his hands from Saria's inner thighs up to her torso, where he palmed her breasts and ogled her toned chest. "So strong… so hard…"

Saria nodded — one of the few things she could do while she was bound and gagged — and her blush only deepened. The Doctor's appreciation of her physique was something that she cherished dearly. To hear it in this context was refreshing and captivating…

Saria watched as the Doctor toyed with her body, running his exploring hands all over her naked form. He traced his fingers along her abdomen, drawing shapes and constellations against her pecs. He pressed in slightly, quietly marveling at his lover's build, and Saria softly sighed through the gag in her mouth, her eyes drifting upward at the sensation of the Doctor's digits pressing into her like this.

He kneaded her breasts with vigor, hardly able to hold himself back. They may not have been the largest on the Rhodes Island landship, but they were certainly nothing to scoff at. Saria was a remarkable woman, and she was well-endowed with her diligence, fortitude, and… assets.

He groped her almost selfishly, causing the bound Vouivre to groan and grind to the best of her ability. She felt like a plaything in his hands, watching him amuse himself with her tits. Watching him squeeze and smack them around, causing the ex-director to whimper submissively atop her lover's desk.

"It's a good thing you're gagged right now," the Doctor teased, "otherwise I think you'd make a hell of a lot more noise than that…"

Saria's gaze carried to the side, but the Doctor wasn't having any of that. He reached out and took her chin in his hand, and he ran his thumb across her gag while he looked down at her. Saria's eyes immediately flicked back to the Doctor's, and she shuddered with pleasure as he loomed over her like this.

"Don't look away," he told her, "look at me. I want you to see the things that I'm doing to you, Saria. Okay?"

She nodded quickly.

"You'll behave for me, won't you, sweetheart?"

The sound that left the bound Vouivre was akin to a pleasured gasp, and she nodded desperately at the sound of that.

"Good girl."

"Mmmm…!" Saria's eyelashes fluttered as she kept her gaze on her precious Doctor, and she watched as he went back to running his hand all over her body. There wasn't a single part of her that went untouched. The Doctor kneaded her breasts and flicked his fingers against her nipples, drawing shuddering moans from the bound wyvern. He traced a finger along her neck, and he leaned in to pepper her collarbone with adoring smooches that had her seeing stars. All the while, Saria could feel herself become wetter and wetter for him. She hopelessly humped the air in front of him, waiting for him to stop dilly-dallying and come fuck her.

Thankfully, it appeared the Doctor wanted the same thing. He came forward and took the gag out of her mouth, causing Saria to gasp aloud and smack her lips together to keep from drooling.

"How are you holding up?" He asked her, tenderly. Saria chewed on her lower lip meekly.

"My body feels like it's on fire," she said with a pleasured sigh. "I want you, Doctor…"

"You want me?" He smiled.

"Please, Doctor… I'm… I want it so badly…"

"Aha… I could get used to this, you know," he teased, leaning forward and planting a sweet kiss on Saria's forehead, just between those dragon-like horns of hers. Saria whimpered quietly, and she nodded with great appreciation for her Doctor.

"Do you want to use your safe word?" He reminded her, and she shook her head in declination. "You want me to fuck you now, Saria, sweetheart?"

Another quick nod from the wyvern was all that the Doctor needed. "Alright," he whispered, and he put the gag back in her mouth before dropping his pants and revealing himself to her. There was that manhood that Saria lusted after so much. She treated it like her greatest treasure. Dragons hoarded their most precious things, after all.

The Doctor stroked himself as he ogled Saria, spread out on his desk like a meal to be savored; one that would melt into his mouth with every selfish bite. He felt as possessive of her as she was of him, and he didn't want to wait a moment longer. He couldn't.

Fuck me, her eyes seemed to say. Her pupils were locked onto his own. Take me. Ruin me. Use me as much as you want. I want it. I need it. Come home to me.

The Doctor made himself at home; he pushed himself forward until his hips met with Saria's, and she moaned through the gag in her mouth as he hilted himself all the way inside. Almost immediately, she was satisfied; he was so filling that it made physical sense for him to occupy her as he did. If she weren't bound and gagged, she would moan his name and wrap her arms around him. Hold him close and never let him go.

As it stood, the Doctor was content to really let Saria have it. He thrust against her with gusto, grunting as he took her, bound as she was to the legs of his work desk. Spread out for his pleasure, there was little she could do; she couldn't move away even if she wanted to.

"Fuck," the Doctor cursed, growling under his breath as he penetrated her. Saria was much bigger and stronger than he was, and to top her felt nothing short of divine. "God, yes…"

He speared her cunt with his thick cock. Every thrust forward sent a shiver down the Vouivre's spine, and her eyes rolled up as her chest rose and fell with her heavy breathing.

The Doctor kept his hands on Saria's thighs, pumping his hips back and forth and causing the desk she lay supine over to creak and groan in time with their motions.

"Mmmfff!" Saria grunted as she was fucked so thoroughly, her breasts jiggling with such intensity that the Doctor couldn't help but take a handful for himself, once again palming the wyvern's mounds while his body crashed against her own.

Suddenly, and before she could think to even warn him, Saria reached her first orgasm of the night. Her entire body went rigid, and she creamed around the Doctor's cock while he slowed his thrusts and urged her to keep going. She trembled around him, shaking atop the man's work desk; she made the entire frame of the table vibrate through her powerful climax. Saria whimpered and moaned helplessly through her convulsions, clenching and unclenching around the Doctor's shaft. The lubrication of her peak made his thrusts slicker and smoother.

But the Doctor needed more. So much more.

He slid his cock out of Saria's dripping-wet pussy, and he slapped it against her crotch while he loomed over her, leering like a predator with his hungering gaze. It was an expression that Saria melted over. Her eyes drifted halfway shut, and when the gag was removed from her mouth, she panted desperately to catch her breath.

"D-Doctor…" Saria rasped. "Doctorrr…"

The man smiled down at her, cherishing the sight of her glazed-over expression. She seemed almost dizzy, and so the Doctor snapped his fingers to get his previous Vouivre's attention.

"Don't sleep just yet, sweetheart," he teased, "we're just getting started…"

Saria ached for him. Oh, how she ached.

She was bent over the desk now, once again bound and gagged and waiting for him to make a move. The wyvern was tied in such a way that she couldn't move her arms or legs, which were spread apart for his enjoyment.

His desk felt so much colder than everything else. Her nipples stiffened as she was pressed up against the polished surface of his workstation. Then, fortunately, she felt so much warmer once more as he came up behind her and clapped his hand over her ass cheek, kneading her rear end as though it belonged to him. As though she belonged to him.

"Are you ready, sweetheart?" He asked, and she nodded immediately as the question left his lips. Without further ado, the Doctor penetrated his larger partner once more — this time from behind — and his hands naturally found her hips while he pushed himself in and out, back and forth, again and again…

He watched his cock vanish inside her folds, and each time he went forward, Saria would arch her back and moan through her gag, craning her neck with pleasure as she flexed and tensed the ropes that bound her to his table. Helpless beneath the Doctor's actions, Saria could do nothing but take it like the good girl she was, silently thanking and praising the man for making her feel so useful, so loved.

From this position, Saria couldn't see what was being done to her. She could only sense it: feel it; as the Doctor fucked her from behind, stuffing her cunt with his hot and thick cock, pounding her against his desk like she'd earned this "punishment." She could hear him grunt and groan right behind her; could listen to the sounds of their hips smacking wetly together, a rhythm to go along with their melodic moans and sighs of pleasure. She could smell their lust; the aroma of their lovemaking was familiar and comforting and helped to make her feel even sexier. It was the scent of sweat and spunk, passion and pleasure.

"God, Saria…" The Doctor moaned. "God, you feel so good… fuck, Saria… You like that, huh? You like it when I fuck you like this?"

Another desperate nod. Saria kept her tail out of the way; she didn't want to strike him with it by accident and put an end to their fun. She loved feeling small and submissive far too much to stop this now. All the while, she bumped and ground against him as best she could, whimpering and moaning almost pleadingly while he fucked her in this fashion.

This is it, she thought, this is true submission… this is genuine pleasure!

She moaned emphatically as the Doctor reached out and pulled her hair, grabbing a handful of her white locks and yanking back with enough force to crane her neck. The great Saria clenched her eyes shut and quivered beneath her mate, panting hard to keep from making a mess through that gag of hers. Ever the diligent assistant, she was.

"You can't help but love this," the Doctor whispered tauntingly, "is that right, Saria?"

She couldn't even nod given that he was pulling her hair, and so she hoped that her lustful gaze would be enough to convince him that, yes, she loved being fucked like this! She craved so much more!

The ropes that bound her wrists and ankles continued to tense and flex through her writhing. They wouldn't come undone — the Doctor made sure of that — and the sensation of being trapped like this for him was frankly almost too much to bear. She already felt close to a second orgasm!

"Are you going to cum again?" The Doctor licked his lips. "God, you're so filthy, Saria… It's no wonder our relationship is so secret. I have to wonder what the others would think of this… if they saw you being bent over and taken. You're a subby toy at heart, huh~?"

That was enough to push her over the edge. Saria squealed through the gag as she reached her another climax, her entire body flexing and trembling beneath the Doctor's as she moaned and cried out through the gag in her mouth. By now the blushing was so striking that even the tips of her ears were cherry red from the pleasure and the shame. As she quivered and creamed around the Doctor's shaft once again, he could only chuckle and praise her.

"Good girl," the Doctor cooed, reaching out and kneading Saria's toned ass cheeks. "There's a good girl… ah, very nice… good girl, Saria, sweetheart…"

His voice was music to her ears. She sank into the tune as she lay her head on his desk.

To cap things off, the Doctor decided he wanted Saria to ride him. This time, he bound her wrists together, but he kept her ankles free. She'd ridden him before, of course, but in this new context, she could be submissive as she settled into one of her more favorite positions.

Saria smiled bashfully. Her hands had been tied behind her back, and so with his grip on her hips, the Doctor wasted no time in taking her from his seated position and sliding his cock into her wet and well-fucked snatch.

Given their size difference, Saria still needed to do some of the work. They didn't mind — he helped her up and down, and with the bit of freedom that he'd given her, Saria was content to show the Doctor just how badly she wanted him.

"Mmmmfff…" Saria moaned through the gag that was still in her mouth, her eyes half-open as she rode the Doctor with vim and vigor, her hips clapping against his own while he sat in his office chair and grunted each time her hot and wet pussy enveloped his snatch.

"Fuck… oh, fuck, Saria…" The Doctor couldn't help but moan her name over and over again. As she rode him, all he could think about was the climax. As she pressed his body against him, it was all he could imagine.

The chair creaked beneath them as she slammed her hips against his repeatedly. Every time she came down, it was another groan of pleasure that they shared. Saria was an exceptional, powerful woman. That he had her all to himself was astonishing.

Though her wrists were bound behind her back, Saria heaved up and down with her darling Doctor's help, and through all his curses and his praise, the two reached a mutual climax that had both shaking and shivering in each other's arms. The Doctor embraced Saria tightly as he came, pumping a hot and gooey load of cum deep inside the Vouivre's pussy, painting her walls white with spunk and filling her with that comfort and satisfaction that she oh-so craved.

"Oh, yes! Yes, Saria! Fuck, yes…!"

The Doctor's hips spasmed against her own while he continued to spurt shot after shot of cum deep inside his precious Saria. As Saria moaned and sighed through the gag in her mouth, she leaned forward and rested her head on the Doctor's shoulder, thoroughly spent from a third and final climax. And how lucky she was to have tried this in the first place…

In the minutes that followed, they could only catch their breath in the space that they shared. Saria's breath rose and fell with her heavy breathing, and it wasn't long before the Doctor removed the gag from her mouth and tossed it onto his workstation, smiling easily at the wyvern on his lap.

"So," he whispered, running his fingertips along her back soothingly, "I take it that means you like being submissive?"

Saria hummed in the affirmative, her tail curling and twisting happily as she stayed nestled in the Doctor's embrace.

Yes, most definitely. She could get used to this…


"That…"

Saria tried to find the words. She blushed even all this time later, as she got her clothes back on and straightened them out.

"...was incredible," she whispered. "Simply incredible…"

"I have to agree." The Doctor chuckled with amusement. "It was simply incredible…"

"Thank you, Doctor…" Saria smiled brightly. "My Doctor…"

"How many times are you going to thank me?" He teased, smiling in kind as Saria walked over, leaned in, and planted a saccharine smooch on the man's forehead.

"It's very fun… playing that role. Being small… is a pleasant change of pace. I could do that more often. I want to do that more often."

"Is that right? Well, then…" The Doctor crossed his arms as he looked up at Saria. "Tomorrow I want you back in this office. I need you here to help me de-stress from work. And I can help you do the same."

Saria raised an eyebrow. "Is that an order?"

"Do you want it to be an order?"

"Mm…" The Vouivre couldn't help but smirk. "Yes…"

"Then that's an order," the Doctor told her.

"Yes, sir." Saria bowed respectfully. "I'll see you tomorrow, D—sir."

"Atta girl."

Saria's smile widened just a little more. With her work day more or less finished, she slipped out of the Doctor's office and dusted herself off, nodding gratefully at Ptilopsis after the Liberi scooted aside.

"Thank you for keeping the riff-raff away," Saria whispered, patting the Liberi over the shoulder. Ptilopsis' thumbs-up was almost mechanical.

"I would let no one disturb you and the Doctor." Ptilopsis looked Saria up and down. "You've definitely had your fun tonight."

"I've learned something new about myself," Saria confided. "Something very interesting."

Ptilopsis held a finger up to her own mouth in a shushing gesture, and she winked.

"Congratulations, Saria. For what it's worth, I knew it all along."
