Too far already

You removed your left hand from her back and stopped the stopwatch once it passed the 2-minute mark. You jotted down your findings before you forgot the numbers and turned to Rebecca with a sheepish smile. As soon as your eyes met you saw that she was pouting at you with a hint of anger in her eyes, almost daring you to move your eyeline down towards her chest that she was still covering with her arms instead of her bra that flimsily rested on her shoulders.

You kept your eyes locked on hers and resisted the temptation to look at her breasts. After seeing you not look down, Rebecca huffed before turning her head to look away from you.

“Are you gonna help me get this back on or what?” she asked, trying to bring your attention to her now loose bra straps without moving her arms away from her chest. Her head still remained turned away so you went to take a quick look at her chest before walking behind her.

“I saw that” she declared, turning her head back towards you before you realised she had been watching you in the reflection of her monitor.

You let out a deliberate cough and moved behind her to redo the strap you had undone.

“Sorry if I went too far. I could feel your pulse lowering towards the end and I just wanted to try something to get it back up. I wasn’t thinking clearly so apologies.” you confessed, finding it harder to put the bra back on than it was to take off.

You managed to put the strap back in the end and Rebecca’s shoulders relaxed with your apology, finally moving her hands away from her chest to readjust her bra. You had been focusing on the experiment for the first few minutes and although you had wasted some of her active effect by not asking her any questions, you decided to try and ask her some questions anyway if you got the chance to work it into the conversation.

“Fine, apology accepted but you just signed yourself up to another pile of tests to mark” she replied, handing you your punishment that you gladly took when you considered staring at her chest to be the reward.

You moved back around the desk and sat in the empty chair before grabbing your stopwatch and notebook off the desk before putting them both into your bag. You zipped the bag back up and when you looked back up, you were surprised to see that Rebecca had made no effort to put her outfit back on and seemed to be content to remain in her underwear. You quickly fixed your expression in the hopes that she wouldn’t find anything out of the ordinary and stay in her bra and panties.

“Again sorry for taking it further than I said I would. I guess the experiment did work though and I was able to keep you feeling embarrassed” you said, trying to show her the silver lining.

“I suppose. I just wish you would have warned me is all” she replied, giving you a brief smile.

“I’ll consult you in the future but I guess if you are prepared for something to happen then the feeling won’t be as pronounced right?” you asked, getting a quick nod and a “that's true” from Rebecca who was starting to look conflicted before you continued.

“That's also why I think the safe word idea would be for the best. It does mean you have to place at least some trust in me to not push too far as hopefully, we would never actually have to use it. Sort of like a fire alarm, if things get too hot then you would rather have a safeguard in place right?” you jokingly asked, expecting a smile in response but she seemed to be thinking about your proposal more seriously than you expected. You weren’t sure if it was the active effect making her want to reveal her true feelings on the matter or what but you let her think without bothering her any further.

“I hadn’t fully considered it as a safeguard to be honest. I thought you were just trying to get away with whatever you could” she teased.

“I’m not gonna lie and say it wasn’t at least partly for that reason but I did want you to have an opportunity to stop and call it quits if you ever thought that I was pushing you too far or if you just weren’t feeling well one day and didn’t want to be hassled” you replied, trying your best to tell her your thought process now that she was telling you hers.

“I’m gonna have to think about it a bit more to be honest but I think we should still set up some boundaries. You are still my student after all and I think we both know that I’ve taken this further than I probably should have” she explained, getting a nod from you in response.

After that, you went through what she considered to be still above board and what was a definite no-go. There was a bit of a grey area in between those two extremes but it seemed like Rebecca was avoiding talking about that even with the KDK active. For example, she said that there should be ‘nothing below the waist’ but there was no mention of her breasts being prohibited. You knew that there was some excitement coming from her about this and in the hopes of getting the rules a bit further in your favour, you decided to bring up a topic that the KDK had explicitly said she would like.

“I know you mentioned this in a completely different conversation but what about stuff like handcuffs. Your story didn’t seem like the best experience but putting them on might increase your pulse. It's up to you if you want to…” you said, starting to explain before she cut you off.

“Oh sure! We can try using them. I kept the pair I had before if you don’t have any?” she said, sounding almost giddy as she agreed.

“No I don’t” you mumbled in response, not expecting her to reply so enthusiastically.

Her happy acceptance of using handcuffs allowed you to start forming a better picture of how her active effect was working. It seemed that if she was asked a direct question then she would act like her internal filter was completely removed and tell you the truth regarding anything you asked. If your question was more open-ended or vague, like with the grey area in your new rules, then she would still not lie but would avoid going further into topics that she was hesitant to delve deeper into.

You thought deeper about the effects of the passives and actives on your subjects while Rebecca seemed distracted by the talk about the handcuffs and realised that you were gonna be late to get to the gym if you weren't gonna leave in the next few minutes. Everything of yours was already packed away so you could leave and walk out the door at any time but the problem was Rebecca herself.

Author's note:
Forgot to add this a few chapters ago but a stats page has been created as an offshoot from Chapter 2. This will be up shortly after this chapter and is accurate to chapter 115. I was supposed to realise it at the same time but I left it as a draft by mistake.
With that hopefully cleared up...
Happy reading :D
