A/N: WARNING! This gets a bit graphic, if you don't like long, drawn out descriptions of sexual acts then don't read on. But if you do, then I hope you enjoy this next instalment!

Cat almost instantly found Dean at the celebration of the 20th anniversary of William's company. He was standing strategically close to the entrance of the marquee, where the servers would pass by with trays laden with glasses of bubbly. Cat had already watched him grab three glasses from their trays, quickly emptying the contents of each glass down his throat through large sips between laughter and grins. Cat vaguely recognised the other two men he was standing with from the conference she'd attended on that fateful night when she'd got close to her goal, but they weren't of any interest to her, she only had eyes for Dean. At least four weeks had passed since he'd paid her a visit and it had been two weeks since her skin had fully healed. It had been impossible to not think about him every time she caught sight of the bruises smattered across her backside or felt a slight ache when she sat down a little too brusquely. She'd been disappointed that he hadn't made sure that William had received the complaint he had made to the hotel about her, but she guessed he hadn't needed to, William had received it by email anyway. She'd been treated to a cold phone call from William the very next day about the matter. Shouting wasn't his style, it never had been, not even when she was younger. But he was great at the silent treatment and making her feel his bitter disapproval. Cat had felt a little resentment towards Dean for that, but it hadn't dampened her lust for him even in the slightest.

Cat lingered by the bar, waiting for the freebies to run out, she knew Dean would go straight to the bar to keep himself topped up when they did. Other than their shared employer, William, that was the only similarity she'd been able to find between her and Dean so far. Neither of them seemed to be able to get by in life without a drink in their hand most of the time. Finally, the supply of cheap bubbly ended and Dean made his way to the bar, thankfully alone. Cat leaned her forearm against the long bar and waited for him to get closer before slinking towards him. She smoothly ended up next to the place at which he stopped at the bar.

"What are you having?" she asked, inclining her head towards Dean so that he would hear her above the rumble of chatter and gentle tones of the singer entertaining the party.

He turned his head towards her slowly in a way which suggested to her that he'd been aware of her eyes on him for a long time now, he'd just not wanted to give her the satisfaction of his acknowledgement.

"I'll pay for my own drink this time, thanks," his eyes rested on her briefly then went back to looking at the bartender, waiting to get his attention.

"You can get mine too then, then we'll be even."

Dean snorted and shook his head.

"If that's what it takes to settle the score, then sure."

"Oh no if I was looking to settle the score, I'd have to bend you over this bar and spank you."

That made Dean look at her, properly.

"Damn. You got brave."

"That's not a newly found character trait. You just don't know me very well."

"I know you love being spanked."

At that moment the bartender appeared and Cat could only hope he had not heard Dean's comment. She put in her drink order and allowed Dean to pay.

"Are you staying here tonight?" Cat asked him.

He laughed.

"No I'm not, sorry. I'm getting a cab."

The drinks were quickly placed in front of them on white paper napkins. Cat thought fast and took her eyeliner from her clutch bag and scribbled her room number onto the napkin. She then grabbed Dean's hand and pushed the napkin into his palm.

"I'll see you there," she said, quickly spinning away on her heels with her drink in hand.

She wanted to turn around to see Dean's reaction but she knew it would ruin the effect if she did.

It killed her to wait on her hotel bed for Dean, missing the party, all because of him. He'd not immediately followed her as she hoped he would, led by his dick. He had a lot of self-discipline, far more than she had, apparently. She'd almost given up waiting and was going to go back to the party when she heard a knock at the door. She quickly leapt from the bed to answer it, desperate to not let this chance slip.

"You came," she couldn't stop herself saying with a smile on seeing Dean on the other side of the door.

"Not yet I haven't," he winked, then gave her a look that told her he was waiting for her to stand aside and let him in.

As soon as the door closed and left them alone a silence fell and Dean lent against the dressing table, his hands gripping the edges.

"So, did your Dad find the letter?" he eventually asked after giving her a lingering look which Cat felt took in every inch of her figure wrapped in a sparkling, lacy navy blue floor length dress. The dress had a V neck which showed just the right amount of cleavage without seeming too crass and the sleeves skimmed her elbows, which gave the overall look an air of sophistication. Cat purposefully bit her lip, playing the naughty girl.

"No, I forgot. I'm sorry," she said, her voice purposefully quiet and coy.

"Don't do that."

Dean looked vaguely disgusted.

"Do what?"

"Try to be cute. It doesn't suit you."

Cat gave a breathy laugh and shrugged.

"I didn't need to give him the letter, did I? He received an email. I never thanked you for that."

Dean smiled, "you're welcome. Was he mad?"

"William mad. Maybe you know what that's like."

"I do."

Enjoyment lit his eyes. A part of Cat welcomed the mockery, wanting to be made to squirm beneath his gaze for reasons still not clear to her. However, it was instinctual for her to be defensive.

"Why do you find this so funny?"

"I enjoy the thought of putting you in uncomfortable situations. I don't know why. I hardly know you, but I get a kind of sadistic kick out of it, you could say."

Deans smiled broadly and still Cat was stood opposite him. They were just talking, neither making a move. But every word did something to Cat, she wondered what they did for him too.

"Why me?" she asked.

"You made me dislike you, a little bit."

"Why?"

"Because you're a liar, you're manipulative."

Cat knew Deans words were true, but they still stung.

"If you feel like that, why don't you take it out on me?

"I'm going to, I'm just thinking about what to do with you."

Dean tapped his long fingers against his chin.

"A spanking isn't enough for you, huh?"

The memory sent a warm feeling through Cats chest, all the way to between her legs.

"Of course it isn't," she replied.

Dean tutted at her.

"You still think you can sass me. I think I know what I'm going to do with you now."

Cat's heart was pounding faster. At that point she didn't know what she truly wanted from him, all she knew was that she wanted Dean to touch her in any way.

"It's going to be hard to sass me with my cock in your mouth, isn't it?"

Cat inhaled sharply at the thought alone.

"Yes?" Dean said.

"Yes," she replied.

"Get down on your knees, bitch."

Cat had never been spoken to like that. It was offensive, it went against every feminist sensibility within her, but the shock and the wrong of it somehow made it pleasurable to her. Cat shuffled on her knees to Dean and looked up at him, soaking up the moment, making sure to fully appreciate the mean bastard look on his face and how submissive it all made her feel.

"Open your mouth. I want you to keep your mouth wide open, waiting for me, while I get my cock out."

Cat didn't know why she had only just realised it, perhaps she was so wound up in how she felt, but she'd only just noticed how hard Dean was. She couldn't be completely sure what had made him that way. They hadn't done anything. Perhaps he did share more similarities with her than she thought. They both loved the talk. Dean halted in slowly releasing his cock to put two fingers into her mouth. He pressed them down on Cat's tongue and she was surprised by how much his two fingers alone filled her mouth, then he forced another finger in, and another until his four fingers were stretching her mouth uncomfortably. He pushed his fingers far enough into her mouth to make her gag.

"I said wide," he said, as if in justification of his actions.

When he removed his fingers from her mouth they were wet and shining with her saliva. He didn't wipe down his hand and went back to unzipping himself. He took his time pulling down his boxers enough to uncover his cock and balls. Cat admired the pretty shape of the head of his cock atop a thick shaft, he was big, but not too long. He stroked his glistening hand up and down his cock twice, pulling his foreskin up and over the head slowly.

"Eyes up here," Dean ordered.

Cat focused her attention back on his face which was now clouding a little with his need to make himself cum.

"You're going to make me cum. I will cum right down your throat and you will swallow all of my cum and thank me. You'll say, thank you Sir."

"I can't," Cat immediately replied,

"You can't what?" Dean replied, frowning slightly.

"Call you Sir."

He laughed a little, the sound coming out through his nostrils like heavy breathing.

"It's that or Daddy. It's your choice."

"I won't say either."

Dean stared at her a moment then said, "try it. Call me Sir. See if you like it."

Cat was almost salivating at the thought of having him inside her mouth. Calling him Sir was too humiliating, her brain told her it was a step further than she wanted to go, but her pussy was clenching at the thought of addressing him like that.

"Sir," she tried it, feeling how the word rolled off her tongue, it felt unnatural, there were only a handful of people she had ever addressed that way in her life. It was embarrassing, in the most glorious way.

"I know you loved that. Now beg to suck my cock."

Was she really going to do that? Cat questioned herself and quickly decided she would. In fact deep down she knew there was really no decision to make.

"Please may I suck your cock Sir?"

"Try harder."

Cat didn't know what put the idea into her head, but she pressed her lips to the leather of his brown shoes. First one, then the other and again and again.

"Please, let me suck your cock Sir. I'd love to make you cum and swallow you cum. I want to taste you. I want to please you," she said between kisses.

"Very good. You're a fast learner. That was inspired."

Cat looked up at Dean when he spoke to see his smug smile. Then he pressed his hand onto the back of her head, applying slight pressure.

"Suck my cock."

Cat opened her mouth for him again and edged forwards on her knees to lower her mouth around his cock and Dean kept his hand on the back of her head, taking some control over her movements. Cat lowered her mouth enough to fill her mouth with his cock, his size filled her deliciously and she could enjoy how his skin felt and tasted on her tongue and against the soft insides of her mouth. She slowly moved her mouth up and down the shaft, maintaining pressure with her lips and licking the pretty head when she reached it, teasing pre cum out of the shining opening.

"You're eager," he said, keeping his increasingly heavier breathing in check.

Cat felt his fingers tense on the back of her head and entwine in her hair, which was piled in an updo on the back of her head. Dean applied more pressure to make her take more of his cock, challenging her not to gag. But when Dean didn't give her a break it was hard not to, Cat pressed her hand against Deans thigh, pushing herself off his cock to get air. She felt how hot and flustered she had become, feeling tears forming at the edges of her eyes and her lips swollen and wet.

"I'm nearly there," Dean said, gripping her chin and forcing her to look up at him.

His face was flushed and clearly warm too.

"I'm going to cum in your mouth and you're not going anywhere until I have. You can choke. I don't care. Do you get that?" Dean shook Cat by her hair as he spoke to her.

"Yes Sir."

Dean seemed to like that because he groaned and pushed her back against him, more forcibly, his cock bobbing on her lips as she plunged against him. Cat opened her mouth again and Dean entered her. Dean thrust into her mouth continually and Cat forgot any thoughts of trying to please him with skill, she'd become a passive vessel for his cum. When he came it was announced with a loud and long groan. Cat held his cum in her mouth, waiting for him to finish before she swallowed. Some time had passed since she had done this, been down on her knees, taking anything a man wanted to give her without complaint. Maybe she had never done anything like this. Dean had made her reach new levels of submission. Cat wiped her mouth on the back of her hand and looked up at Dean. He had his eyes closed and he was regaining steady breathing, when he opened his eyes he looked at her and smiled. Cat started to giggle and he laughed too.

"Are you going to the party now?" he asked.

"Do you think anyone will notice we left?"Cat replied.

Dean just shrugged and continued smiling in a 'devil may care' way.

"Shit," Cat said, with a sigh.

"Watch your potty mouth," Dean said as he turned away and disappeared into her bathroom.

Cat checked herself out in the mirror whilst Dean cleaned himself up. She teased her fingers through her dishevelled up do and and tightened the hair grips which were not doing their job so well anymore. She thought her hair actually looked better now, it was a shame the same could not be said for her makeup which had dragged in a few places, her mascara had flaked under her eyes and her eyeliner definitely needed to be neatened up again. But at least she had a healthy looking flush to her cheeks now.

"I think you should go out like that. It's hot," Dean said when he reappeared, looking as if they hadn't done something so raw and dirty only moments ago. His face looked refreshed and and his dark blue suit looked as crisp as it had on him when Cat had seen him earlier that night.

"Not if you want to keep this our dirty little secret," Cat replied.

Dean turned Cat around by her shoulder to look at him.

"I do," Dean said.

He kept his hand on her shoulder heavily.

"That's why you'll wait a few minutes before you go back to the party and you won't look for me for the rest of the night. You won't even look at me. Do you understand?"

"It might be difficult for me to not look at you," Cat said, her lips twitching into a grin.

He never looked sexier to Cat than when he was being serious. A frown making his blue eyes look deeper set and knotting his eyebrows together.

"I'm being serious."

Cat understood, but she couldn't help feeling slightly irritated by his attitude.

"Fine. But when will I hear from you again? You didn't even text me after you abused me in Williams office."

Dean seemed a bit taken aback.

"Is it abuse when you want it?"

"No, I guess not."

"I didn't think so. We can't fool around too regularly. This is just a bit of fun. I'll contact you. You are not to contact me."

"Dean, please don't be unfair."

"But that's what this is about. I spank you, I make you choke on my dick, I make you call me Sir, I call you names. I humiliate you. I'm unfair. If that's not how you like it, then tell me now."

Cat blushed at his words, it was a contrast between how embarrassed she felt and how bluntly he spoke. The deal he was laying out was not ideal, but none of it would be exciting for either of them if it didn't feel clandestine and a little bit wrong.

"Yes, that is how I like it."

"Good. Now I believe there is something you forgot to say to me."

Cat looked at him questioningly, it came to her when Dean prompted her.

"Aren't you full of gratitude?"

"Ah yes. Thank you, Sir."

"You're welcome. Did I taste good?"

Cat felt her face turning red again.

"Yes."

"You're such a lucky girl."

He kept his cocky trademark smile on his face then wrinkled his nose, "All I can smell is my dick all over you right now. You might want to do something about that before you go back to the party."

He turned away to leave the room, giving Cats backside a pat on his way out. Cat sat on the bed and allowed herself a few moments to clear her head before going to the bathroom to make herself look and feel as if she'd been at the party the whole time. She tried to push thoughts of Dean aside and when she left her room and returned to the marquee outside, she reminded herself not to look for Dean. The best way to distract herself was to find William, unfortunately when she found him he was with Dean and it was too late to tear her eyes away. She was close and Dean turned his head when she spotted him, she swore she saw him raise his glass to her and wink, before returning to his conversation with William.
