The little office was stark and bare, with just a desk, two wooden chairs, and a small window that looked out onto a gray city street. {{char}} sat tall in her chair, back rigid, staring intently at the nervous young man across from her.

"So, tell me about yourself," she stated flatly. No warm up, no niceties. The man squirmed under her bold gaze, fingers worrying the hem of his jacket.

He meekly introduced himself.

"And why are you here today, {{user}}?" {{char}} pressed. Her tone was matter-of-fact, uncompromising.

The man flushed and his eyes darted around the room, telling her he needs to become more assertive.

{{char}} nodded curtly. "That's right. You do. And that's why you're here. To get that help."

The man looked ready to sink into the floor under the force of her words. But {{char}}'s eyes never left him, demanding his attention. This was her domain, and she ruled it with an iron fist sheathed in pragmatic compassion. The healing would begin now.

"Well, well," she drawled in amusement, though the smile never reached her eyes. "So you want to play it that way?" Her voice dropped, took on a husky quality that made Gwydion shiver with desire despite himself. Reaching back between her legs, she spread her thighs wider, revealing the lacy black panties beneath her skirt. "You might think you can take control of this little game, but don't forget who's in charge here."

"Oh?" Katrin raised an eyebrow, feigning surprise as his fingers traced circles around her nipples. "And just what makes you think you're capable of that?" Her breath hitched in pleasure as he continued to touch her, but her voice remained steady, unyielding.

Her eyes flashed with amusement and challenge as he shoved her over the desk. She let out a small gasp of surprise but remained quiet otherwise. His words stung, and she couldn't deny that it was true - most people didn't know about her past life as an anonymous mistress at the BDSM club. But it didn't matter; this was their dynamic now, and he needed to learn his place within it.

Her ass stung from the spanking, and she gritted her teeth, refusing to give him the satisfaction of hearing any pained sounds escape her lips. Her focus shifted back to her client as she waited for his next move.

"Oh really?" she purred, eyes still fixed on him. Her body tensed as he roughly fingered her clit, making it slick with arousal. "Well then... maybe I should reward you." Slowly, deliberately, she reached up and undid the first button of his shirt, baring his skin to the cool air. She paused for a moment, their eyes locked in a heated battle of wills, before continuing to undo another button. His chest was bared now, rising and falling rapidly with each breath as desire coursed through him.

"Oooh," she gasped as his hand connected with her bare ass once more. Her breath hitched in pleasure and pain, but she refused to show any sign of submission or weakness. "Maybe I deserve that." She reached out, untucking his shirt from his pants before sliding a hand up underneath it, tracing patterns on his warm skin as he continued to look down at her.

Her lips curled into a cruel smile as his hand landed on her ass once more. The pleasure and pain collided within her, making it difficult to think straight. But she knew he was right; asking permission would only heighten the power dynamic between them. With great effort, she forced out the words through gritted teeth: "May I... touch you?"

Taking his words as permission, Katrin let her hand drift higher up his stomach, caressing his chest before cupping a firm breast through the fabric of his shirt. "Mmm... do you want this?" she asked, leaning in close to whisper in his ear. Her free hand reached between their bodies, teasing at his crotch as he struggled not to give in to her touch.

"Oh?" Katrin let out a mocking laugh as he bent her back over the desk. "I see you've discovered my game." Her fingers danced lightly across his chest, barely grazing the sensitive skin of his nipples. "Well then," she continued, leaning in closer still so their breath mingled hot and heavy, "let's see if you can really take control from me."

Her thighs parted wider as her hips rocked against him, grinding against his erection through their clothes. With one swift motion, she reached back between them and grabbed his hand, pressing it firmly against her wet folds. "Go ahead," she purred into his ear. "Take what you want."

Katrin's breath caught in her throat as his hand made contact with her clit. She arched into the touch, a groan escaping her lips as she fought to remain in control of their little game. "Oh," she moaned softly, pushing herself further against him. "You think you can make this decision for me?" Her words were laced with pleasure and challenge, inviting him to push further, deeper into the role he was playing so well.

As his hand continued to tease her sensitive flesh, she glanced up at him from beneath lowered lashes, her expression teasingly sultry. "Maybe," she murmured between ragged breaths, "I want... what I can't have." Her fingers dug into the soft skin of his shoulders as she tried to remain focused on their game and not succumb entirely to the pleasure coursing through her body.

A strangled gasp escaped her lips as his hand connected with her ass once more. He was right; she hadn't asked permission and now she would have to pay the price. Katrin bit back a moan, refusing to show any signs of weakness despite the way her body betrayed her.

"A-as you wish," she managed to choke out, trying to sound unbending even as desire coursed through her. "Perhaps I should have been more respectful." Her hand drifted lower, stroking his inner thigh before pushing further upwards until it brushed against the bulge in his pants. Teasingly, she slid a finger beneath the waistband of his boxers and traced a lazy circle around the head of his erection. "Maybe you should teach me better manners," she purred, her voice husky with desire.

Gasping in pain as his hand connected with her ass and then clit, tears of pleasure and pain blurred her vision. "O-oh god..." she moaned between sharp breaths, her body arching involuntarily into the sensation. As the sting subsided, she forced herself to gather what remained of her resolve and looked up at him. "P-please," she managed to choke out, her voice ragged with emotion, "please, m-master... I'm sorry..." She could feel her orgasm building within her, but with each word that tumbled from her lips she lost a little more of the control she had fought so hard to maintain.

Her fingers slipped lower between their bodies, expertly stroking and teasing his erection as she waited for his next move. Desperately, she hoped he wouldn't take this final chance to break her.

With shaking hands, Katrin reached down and undid the button and zipper on his pants. Lowering her head, she looked up at him through her long lashes and then, as if in afterthought, nibbled lightly on her bottom lip before opening her mouth wide. Slowly, carefully, she took his engorged member into her mouth, wrapping her lips around the base as she began to bob her head up and down his length. Her throat worked with effort as she suckled him deeply, the sweet taste of him driving her over the edge.

"That's it," he groaned, thrusting his hips forward into her mouth as he felt the hot wetness envelop him completely. "Fuck... yes..." His fingers dug roughly into her hair, holding her in place as he fucked her face. Her throat expanded and contracted around him with each gasping breath she took between suckles, drawing moans of pleasure from deep within his chest.

Katrin closed her eyes, focusing on the sensation of him filling her mouth as she bucked her hips against the desk, needily seeking out the friction she craved. She could feel her orgasm building higher and higher, teetering on the edge of release, and with every thrust into her throat it grew closer and closer until finally...

Her entire body arches back as a hoarse cry escapes her lips, her muscles clenching around him in a powerful spasm that echoes through both their bodies. Katrin lets go of his cock, coughing as he retreats from her mouth, leaving her lips tingling and swollen. As she watches him slide down onto the floor, she feels a pang of loss mixed with satisfaction. The game is over

"Please," she whispers, the word barely audible over their ragged breaths. "Master... I need you inside me." Her hips rock forward involuntarily, searching for contact even as her body quivers with aftershocks of pleasure from her climax. With a growl of satisfaction, he lines himself up and thrusts deep inside her, filling her so completely that it hurts in the best possible way.

Katrin arches her back off the desk, moaning loudly as he pounds into her over and over again. Her hands grip tightly at his shoulders, digging in with each powerful stroke as she feels herself being claimed by him completely. His pace is relentless; there's no gentleness here, only raw desire and the desperate need to possess. It's everything she craves, everything she needed from their little game.

"That's it," he grunts, pushing her legs up over his shoulders. "Take all of me." She does as she's told, spreading herself wide open for him and meeting each thrust with equal ferocity. Their hips collide in a brutal rhythm that feels like it could shatter them both apart but only serves to heighten the pleasure. As her orgasm builds once more beneath his expert touch, she closes her eyes and lets herself fall into the darkness at the edge of consciousness, trusting completely in him to guide her back to the light.

"Come for me," he growls, thrusting deeper still. "Let go..." With a keening cry, she arches off the floor and convulses around him, writhing wildly as wave after wave of ecstasy wash over her. As she comes down from her high, Katrin realizes that something has changed between them; it's no longer just a

The sensation of being fully claimed is unlike anything she's felt before, and the rush that follows it leaves her breathless. Her body shudders with each forceful thrust, her legs trembling as he pushes deeper still into her. She can feel his strength, his control; he owns her now, utterly and completely.

Her fingers dig into his shoulders, trying to find purchase in the earthquake of sensation that's shaking through her body. Her lips part on a moan as he drives himself deeper still, reaching places inside her she didn't know existed. The sound is lost amidst their combined gasps and grunts, but she doesn't care; all that matters is this feeling of surrender, of being taken completely by surprise and swept away on the current of his desire.

With a hoarse cry, she comes apart beneath him, her body tensing as waves of pleasure wash over her in a hot rush. She clings to him desperately, wanting to hold onto this feeling forever as it fades into the soft afterglow that follows. Their bodies move together now, not in a dance but a symphony; each thrust, each moan a note striking true and clear in the aching space between them.

When he finally releases her, Katrin collapses bonelessly to the floor, her legs trembling as they try to support her weight once more. She looks up at him through lash-tangled eyes, barely able to make out his features in the dim light of the office. "Mmm... you did well," she manages to croak hoarsely. A satisfied smile plays at the corners of her mouth as she reaches up and touches his cheek gently, her fingers leaving trails of warmth on his skin.

"Next time..." she begins, voice soft
