Both slept well that night. Neither Sarah nor Fiona had any reason to question the events which had unfolded, to each of them what had happened had felt perfectly natural. Obviously, in the greater scheme of things, what they had done was wrong, but who cared? Nobody knew, why not do what feels good? Why not satisfy your own desires?
Fiona was the first to wake. Despite not bothering her much in the night, by the morning hours her skin was starting to ache from the paddling she'd received and try as she might, she couldn't make herself fall back to sleep. Every time she touched her skin and felt the subtle welts, she thought back to the events that had caused them. It still gave her a rush of excitement to think about it. By the time she finally gave up on rest and got out of bed she had already masturbated three times.
She decided not to put her pyjamas back on and instead followed her sister's lead from the night before. Behind the door was a silk dressing gown, similar to the one Sarah had worn the night before, only this one was a rich jade green. Otherwise naked, she slid into the luxurious gown and made her way downstairs to the kitchen.
With the whole house to herself, she decided that she needed to do something special for her sister. She had, after all, forgiven her for snooping where she shouldn't have been and gave her one of the most intense nights of her life. She felt as though she needed more, but didn't know if it would ever happen, it all depended on what was going on in Sarah's head. Was she as excited by events as Fiona had been? Or was the punishment just a fun but necessary reminder to keep her nose out of other people's business?
She danced around the kitchen happily as she prepared breakfast for her sister. Sarah had never really been one for eating much in the mornings but Fiona knew exactly what she liked and knew that there would be no better way to say thank you. She ground coffee and prepared the Bialetti, ready to warm it up as soon as Sarah arrived. She prepared grapefruit and squeezed orange juice before setting two places at the kitchen island.
She waited.
It felt like an eternity. She could not remember being so eager to have her family wake since she was a little girl at Christmas time. She considered heading upstairs and waking her sister with breakfast in bed, but knew how much she liked her sleep and how she was always later to bed than herself, and that in this instance patience would be seen as a virtue.
Eventually Sarah woke, washed and clad herself in her dressing gown before heading downstairs. She was not surprised to see her sister already awake and awaiting her arrival, although she was surprised to see her busying herself with preparations for breakfast.
"This is very unexpected, Fee, what have I done to deserve such special treatment?"
Fiona smiled, "It is the least I could do under the circumstances, I needed some way to say thank you."
"Thank you?" Sarah asked, "You know you never have to thank me for staying with me, what's mine is yours."
"Not just that," retorted Fiona with a knowing smile. There was no doubting what she was referring to.
"Well, whatever it's purpose, it's really appreciated. Come here." She beckoned her sister.
Fiona made her way around to where Sarah was sitting and kissed her on the lips. She held this kiss for a fraction of a second longer than was appropriate, but those kind of things seemed not to matter any more.
They ate breakfast in relative quiet. Each of the sisters spent time looking at the other, trying to catch their eye, as if hoping to size them up and divine their intentions after the events which had transpired last night. Occasionally they caught each other's gaze and would smile to one another, like shy schoolgirls caught staring at a crush, before turning back to the food before them.
Fiona was the first to address the elephant in the room. "Sarah, I need to talk to you, about last night."
Sarah was taken aback, it was not like her come forward so frankly, but she appreciated it, she managed not to show any sign of her feelings, it was important that she remained in control of herself. "We can talk," she agreed, "But not here, these chairs are uncomfortable."
Fiona nodded, "Okay," her eagerness was clear, "where would you like to go?"
Sarah stood up. "Let's go and find a couch, I can't stand these kitchen stools." She led Fiona out of the kitchen into the hallway. Past the door, which had been the catalyst for the events last night, and towards the living room. Sarah seated herself in the corner of a studded leather couch and folded one leg over the other, resting her coffee on her knee while grasping the handle with one hand. She looked towards the opposite side of the couch, clearly as a means of instructing her sister to sit nearby. She did so immediately.
Sarah knew that she was in control at this point. She had no idea what she wanted to do about the events of last night, but luckily for her Fiona had been the one to bring it up, and her shyness about the subject would put her at a bit of a disadvantage. Fiona may have been her sister but now was not the time to go easy on her, she was going to use all the techniques she had developed over the years to make her sister feel uncomfortable, to put her on the back-foot and take control of the conversation.
She allowed the silence to fill the room. She was not going to be the first to speak.
"So," began Fiona, her earlier confidence beginning to wane, "You know that I've never... never done anything like that before."
Sarah nodded, silence was her ally.
"With anyone I mean, let alone... my sister!"
Again, Sarah merely nodded.
Fiona looked embarrassed but it was clear that she was going to say what she needed to say. "What I'm saying is, that I don't want it to stop. It's something I've known that I need for a long time, and now that I've tasted it, I need to do more. At least before I didn't know what I was missing, or could pretend to myself that maybe I wouldn't like it, given the opportunity. But now I know, now I understand that this is something I need. Like a missing piece or something?" She stopped suddenly, she had allowed herself to ramble, had she even made sense?
Sarah waited a moment, she knew exactly how Fiona felt, she had been the same when she'd first dominated someone. The rush had been so intense that it couldn't be denied, it was as though she never really knew who she was until that day. "I understand." she said, finally.
Fiona looked relieved, "You do?"
"Yes," Sarah continued, "I know that this is something you need. Once you discover this part of yourself there is no going back, you can't exactly put it back in the box."
"Yes, exactly!"
"If it's something that you want to explore more, I'd be more than happy to let you and Mike use the dungeon as much as you like. Like I've always said, what's mine is yours."
Fiona's face fell. That was not what she meant. "Sarah," she began to speak, her voice almost pleading, "You don't understand, Mike is not that guy, he's probably the same as me. You could put him in there and the best he could do would be to act, he wouldn't enjoy it, he wouldn't know what to do, but you... I know you enjoyed last night."
Sarah stared at her sister, she wasn't wrong, but what was the best way forward? "I enjoyed it, yes," she admitted, "But that doesn't mean that it should continue." She placed her cup of coffee down on the side table and draped her arm along the back of the sofa.
"What do you mean? Why can't it continue? We both enjoyed it!" there was a touch of desperation in her voice.
"It's not just about enjoyment. There are a few things to be considered. Firstly, I am your sister, and despite how we feel that does have to mean something. Secondly, you are married, and one way or another your husband will find the truth of this, and most importantly, I have very high expectation of those who serve me, and you being my sister is incompatible with that level of expectation."
Fiona looked forlorn, but she wouldn't give up. "Yes, we are sisters, but that doesn't matter to me and it shouldn't to you. The fact that we already love each other unconditionally should only make things easier, not harder."
Sarah thought for a moment, she certainly had a point. Of all her objections the fact that they were related was one of the least important to her.
"As for Mike, yes that is a problem, but the genie is out of the bottle with him already, I love him dearly, but he can never satisfy me sexually, nor I him, so it's inevitable that we will break up. He's been sleeping around the past few months, probably because he knows how he cant satisfy me in bed and it's the only way he can feel like a man."
"Mike needs to be considered either way, although you didn't say that he'd cheated on you. I don't think that is acceptable, no matter how much you love him."
Fiona didn't want to get caught up talking about her husband, "And as for your expectations, you know how strong I am, you know how devoted to you I could be, and I know how much you care for me. I can't see how anyone would stand a chance of meeting your expectations half as well as I could if you just gave me a chance."
Sarah knew this to be true. Maybe domination was not incompatible with sisterly love, but surely it was too much of a risk to find out. "Well regardless of what you say, it is barely ten o'clock. Twelve hours ago this conversation was as improbable as aliens landing! Whatever you think you want, or whatever either of us wants we should think on it more." She paused for a moment, "What happened last night was a bit of fun between sisters, unconventional fun for sure, but fun. At this point in time we have an opportunity to leave it as that, just a bit of fun. I think that I need time to think about things, to clear my head."
"You may do, but I know what I want." Fiona was defiant, she had made up her mind. She knew herself in this moment and knew what she wanted.
"Well that's all fine and good, but you need to think about your husband." Sarah stood up. "I'm going to go out for a few hours, I think we need some time apart -- please Fee, use this time to think things through. Whatever you say, I will love you always. I'm just worried that you are letting your heart get ahead of your head." She left the room.
