"Okay!" Klara said excitedly. "Strap me in!"
"Great!" Chloe matched her enthusiasm and cute smile. "Follow me through here, this is the lab you'll be spending most of today in."
On entering the lab room, Klara's jaw dropped in awe at all the machinery placed around the room, no doubt used for several other experiments conducted here. But most interesting to her was a large table placed in the centre, where she was probably going to be tied up. The top seemed to be lined with leather to ensure she would be comfortable while lying down on it. The four corners of the table each had cuffs to restrain her from her wrists and ankles, and more restraints could be seen all around the surface of the table, about to be used to tie her up all over her body. Klara noticed that the table wasn't hollow underneath - instead, it was more like a large solid block. She could tell that the block had several currently closed compartments, and wondered what would come out of them.
"If you could just take off your clothes and lie down on the table, that would be great. Don't worry, there are no cameras in here, it's just going to be me observing you."
Klara happily complied, stripping down naked and making her way to the middle of the room. She lay down as requested and felt her heart beat faster as the moment she had been waiting for was getting closer and closer. Chloe walked over to her and first cuffed her wrists, stretching her arms out above her head. This was followed by her ankles being grabbed and cuffed as well, forcing her into an X shape with her legs spread wide open, at more than a right angle.
"Could you try to move your hands and feet around, please?"
Klara nodded and immediately tried to pull her hands and feet out of their restraints, but found that she had been stretched taut with absolutely no possibility of movement. Chloe was satisfied with this and moved on.
"For this experiment it is also vital that you cannot move your pelvis and chest at all. Even an inch of movement could jeopardise today's results. I'm going to apply a few more restraints around you now."
Chloe moved over to Klara's side and reached over her to grab a restraint fixed to the table near her hips, and tied tightly it around her waist. Klara found that she could no longer lift her pelvis up at all. Next, her thighs were tied to the table, ensuring that Klara had no way to close her legs. She shuddered at what her already wet pussy might go through, now that it was completely exposed and she had no way of moving it. More restraints were also applied around her upper arms, making sure Klara's upper body was just as trapped and vulnerable. She tried shaking her whole body and was shocked to discover that absolutely nothing moved, apart from her hands, feet and head. There really was no turning back now.
"Great, I think we're ready to start the experiment. I'm going to be watching from behind that mirror so just pretend I'm not even here. Just relax and we'll be done in no time." Chloe gave her a warm smile before walking out the room, leaving Klara alone, completely naked and tied up, wondering what would happen next. She was a little confused as she thought Chloe would be the one administering the tickling. If no one else was going to enter the room, who was going to actually be experimenting on her?
Klara's thoughts were interrupted by Chloe's voice filling the room from some speakers.
"Comfortable?" Klara gave a nervous thumbs up and stared at an ominous looking machine that had placed itself on the ceiling directly above her. "Good. We're going to begin now. Don't worry about the large device above you, it is going to be measuring things like your heart rate and breathing, and recording all of this data for the experiment. It does it all without needing to be in physical contact with you, which is great. The more of your skin we have access to, the better." Chloe laughed a little as Klara gulped, realising the implications of that statement.
Klara heard some mechanical whirring coming from underneath her - the compartments on the sides of the block were opening up. She let out a soft giggle and tried to relax as she braced herself for the day ahead of her.
