"You didn't say Amy," Amy said quietly into Sarah's ear as she passed by. "You know how you have to address me. There will be consequences."
Resisting the urge to look back, terrified inside that she'd massively overstepped the mark, Amy walked over to a group of people she knew and joined their conversation. Glancing over after a minute or two, she saw Sarah still stood there, staring at her in surprise and with a hint of anger. The noise of many conversations swirled around them at their firm's annual drinks reception, but for that moment the events room on the top floor of their office building may as well have contained just the two of them.
Amy could feel her heart thumping in her chest as she saw Sarah start to walk in her direction. Had Amy misread the significant look that Sarah had given her when she'd informed Amy earlier that tonight she definitively expected Amy to be submissive to her? What if Sarah actually didn't want the tables turned on her that night? Had Amy misread the roleplay between them? When she reached Amy's group Sarah said with a smile to the others, "Sorry to interject, Amy... do you mind if we have a quick word about the project we discussed earlier? It won't take a minute."
Making her apologies, Amy followed Sarah until they were in a corner of the room, out of earshot of any potential eves droppers.
Looking Amy in the eye, Sarah said sternly, "We talked about this earlier. We'd agreed that tonight I'm in charge, not you." Sarah leaned forward and whispered to Amy, "I was going to tie you to my bed and make you cum so many times later, but now, after that, I think we might need to do something more... corrective."
Amy stood still, staring back at Sarah, her cheeks burning slightly with arousal at the thought. She didn't know what corrective action might entail, but she'd like to find out one day. But... this was a battle of wills and Amy knew that she had the upper hand after what had happened last between them a couple of weeks before in that LA hotel room, when Sarah had completely and utterly surrendered all control to Amy for the first, and so far only, time.
Putting on her sweetest smile, she replied, "No. No we won't. If you want to spend the night with me tonight, then we do it my way or not at all. If you want someone to submit to you go and ask one of your other mentees, I can see Rebecca stood over there, I bet she'd be willing. But I don't think you want that... there is something that I can give you that no one else can. Our secret. You can be mine to do with as I please, not the other way round. Your choice."
As Amy said it, she couldn't quite believe the words coming out of her mouth. She'd never done something like this before and she didn't know if it would work. She could see Sarah hesitate, thinking, before Sarah replied, "This isn't how you and I work. You know that. We'll talk about this later." Sarah turned to go to talk to some other people.
"I'm changing how you and I work," replied Amy still smiling, causing Sarah to stop. "And I think that's what you want, deep inside. So... like I said, you forgot to say my name."
Sarah stood there, looking at Amy with an impossible to read expression. Finally, after a long pause, Sarah looked down then back up at Amy, saying quietly, "Not in public. Later. At my flat."
"Yes in public. Or are you disobeying me?"
Sarah just stared at her, but Amy could see her wavering.
"I'm starting to think you might not want me to fuck you later?" teased Amy. "Might not want me to tie you up and make you beg to cum? Might not want me to have you naked and helpless, subject to my every whim?" Jesus, thought Amy, what am I saying? Is this me now? But she could see that her words had resonated with Sarah.
Sarah took a deep, shuddering breath, then said, "At least don't make me say your name in front of anyone else?"
"That's fair."
"Ok... I'm sorry Amy."
Amy smiled, then leaned over again to whisper to Sarah, "That's better, but too little too late. Come with me."
"Yes Amy."
Amy led the way as they both left the drinks discretely, looking for all the world like they had to get back to work, before Amy found a deserted corner of the floor below and led Sarah into an empty conference room, locking the door and closing the internal blinds looking onto the corridor.
As soon as they were alone and in private, Amy led Sarah to stand facing the conference table, then, after planting a soft kiss on Sarah's neck, whispered into her ear, "Bend over for me."
"Yes Amy," replied Sarah, bending over to lay her front on the table, pushed up on her elbows, her feet slightly apart. Taking a second to admire the sight of Sarah's toned legs leading down to her high heeled shoes, Amy lifted up her dress and pulled down her tights and underwear to her knees, leaving Sarah's ass bare. Amy could see how wet Sarah had got in anticipation, the telltale glistening in her trimmed pubic hair visible under the bright lights of the room.
"Please Amy, be quick... in case someone comes in."
Amy laughed. "Of course. This is just a preview of later." Amy slipped one hand down to brush lightly against Sarah's pubic hair, drawing a gasp. "You like this?" teased Amy, slowly and gently toying with Sarah.
"Yes Amy, a lot."
"Admit it, you wanted this all along, didn't you?" As she said this, Amy slid a finger into Sarah, bringing a shuddering moan.
"I... I can't..." replied Sarah.
"You can't?" said Amy. "You want me to stop?"
"No... please don't," replied Sarah, punctuated with another shuddering moan. "I didn't know I wanted this Amy, but I do. I really do. I'm yours."
"Right answer... You forgot to say Amy earlier, didn't you?" Sarah nodded. "I need to spank you, don't I?" Sarah nodded again. "Say it, what needs to happen?"
Another shuddering moan. "You need to spank me, Amy. Hard."
"Why do I need to spank you?"
"I've been bad Amy." Another moan.
Amy drew her free hand back and brought her palm down hard on Sarah's bare ass. A loud smack sound echoed around the room while Sarah let out a quiet cry.
"Was that ok?" asked Amy, worried that she'd been too rough.
"Perfect Amy, please don't stop."
Amy did as asked over the next few minutes, landing five more hard spanks on Sarah's ass, all while her fingers on her other hand teased and played with Sarah. Suddenly Amy pulled her hand away, sensing that Sarah was on the verge of orgasm.
"Please don't stop, Amy," moaned Sarah, looking over her shoulder back at Amy. "Please..."
