Calibration Addict (4)

With school and deadlines piling up, November became a very hectic month. Cassie did not have the time to think about anything else for the two weeks with examinations and project presentations.

It was finally Sunday and Cassie woke up for the first time in a long while feeling fully rested. Exams were over, and every project that needed submitting was turned in. She had no idea how everyone survived the chaotic end of the term period, but it was finally over.

From now until December, Cassie did not have any classes. School was closed for the winter break, and many of her schoolmates were moving back to their hometown to spend time with their families until the next year.

Unlike them, Cassie had no such desire. She wasn’t particularly close with her family and Jake was far too busy to visit her. The lockdown wasn’t as terrible as it was a few weeks back. It might be due to the holiday seasons that the government became lax about safe distancing measures.

The sophomore rolled out of bed and looked at her tangled hair in the mirror. She was bored. There wasn’t much to do around, and it was too cold to venture outside. Maybe it was better to stay indoors and watch some N*****x.

Making brunch and grabbing some coffee, Cassie looked at the horrible state her room was in. The apartment was messy with many unwashed dishes, uncleared takeout boxes and piled up laundry everywhere. Maybe N*****x could wait. She should take care of the aftermath of finals week.

The next three hours were spent cleaning her apartment from the front door to the bedroom. Cassie had no idea there was so much to be done. By the time she was done with everything, including polishing her bathroom tiles, the woman was close to passing out from exhaustion. She needed a shower and maybe a nap.

On her way to the bathroom, Cassie tripped over something from under her bed and cussed loudly. Clutching her injured toe, Cassie glared at the offender and blinked. What was this fanciful box or? She didn’t remember buying such a thing.

Curious, the sophomore opened it and blushed at the limited edition vibrator set inside. Oh, yes. Now she remembered what this was. Ever since Jake signed them up for the NNN challenge with Wanda’s, they minimised contact. It wasn’t on purpose because they were both busy, but it was Jake’s idea to avoid any form of flirting and stick to texts because something about hearing each other’s voices could be a turn on.

Well, it didn’t really matter now that she remembered the vibrator set. Jake probably didn’t even open his or calibrate any of those toys. He only read the instruction manual for the sake of his girlfriend, who wasn’t a fan of instructions. Now that Cassie thought about it, wasn’t this a good time to try the other toys?

The last time she used the yellow bullet vibrator, she almost touched heaven. Cassie had no idea her body could be pushed to that kind of limit, and honestly, just thinking about the explosive orgasm made her throat dry.

Since she was sweaty already and needed a shower, she could definitely calibrate some of the other toys, right?

It wasn’t as if there would be any major consequences for failing the NNN challenge. This limited edition vibrator set already belonged to them, and Cassie didn’t really want that customised love android sex doll. That was more of Jake’s thing than hers. They weren’t very much into sex toys either, so earning a membership with the company or getting discount vouchers didn’t seem appealing enough.

If she was going to get herself off, how would the company even know? It was just dumb in all. As long as she doesn’t get outed, nobody would find out. It wasn’t as if there were trackers in these toys, right? They were just really high-tech vibrators. 

Opening the Wanda app, Cassie wondered which toy she should try next. The last time she tested the smallest bullet vibrator. Should she opt for a different toy this time or try a different bullet size? If the small bullet vibrator felt that good, she wondered how the bigger ones would be. After all, they say that bigger cocks were better fucks. Surely the same logic would apply to vibrators too, right?

Eager to get the party started, Cassie decided to select the medium-sized bullet vibrator. She didn’t want to be overly ambitious. After all, good things should be slowly savoured. She had the entire afternoon and looked forward to the number of times it could bring her to the peak.

Stripping her sweaty clothes, Cassie tested the vibrator. It was low on battery but would suffice for a while. After a quick shower, Cassie quickly grabbed the bottle of lube by the counter and applied a generous amount. She wasn’t sure how the toy would work without the help of the app. Maybe she didn’t have to go through that tedious calibration process to achieve what she wanted.

The lube made it easy for the medium-sized toy to enter Cassie’s tunnel. However, compared to the smallest yellow bullet, the medium-sized bullet did not sit nicely where it should. Cassie tried to shift it around with her fingers, but it still felt like an uncomfortable tampon.

Giving up quickly, the sophomore referred to the website and app for help. She quickly found her answer and groaned. No wonder Jake told her that calibration was a tedious process. Every single toy had to be calibrated for maximum efficiency. The data collected by the app was sent back to the company as feedback for future improvements. No wonder they gave away free goods. Nothing was actually free if the participants had to cooperate with a tedious calibration process.

Luckily for the company, Cassie had time today. Reluctantly, she entered her information for calibrating the medium-sized bullet vibrator today. Syncing the toy to her Bluetooth, Cassie followed the instructions.

Having done it once, the process was now a lot easier. Cassie sped through the external calibration possess easily but faltered when there was a slight difference in the calibration locations for the medium-sized bullet vibrator after the external sensitivity test.

“Kindly insert the vibrator while holding your legs closed together, as shown in the illustrated diagram.”

Cassie stared at the app for a long time as the picture demonstrated how she should close her thighs tightly and insert the bullet vibrator from behind. Why was there a difference in insertion methods? Did it really matter?

The more she studied the tutorial, the more puzzled Cassie felt. Was there really a difference? Wouldn’t closing her thighs together make it harder for the toy to be inserted? It wasn’t comfortable before, and it would be difficult in this position.

Yet, she wasn’t a sexpert. Following the diagram and taking its advice to lie sideways while inserting the medium-sized bullet, Cassie immediately felt a difference.

Unlike the small-sized vibrator that could be tucked into position easily, the medium-sized vibrator needed more effort to reach deeply inside her. In the position with her legs closed, the vibrator was able to slip in using the force of her pelvic floor muscles. Pushing it past the pelvic floor muscles was difficult at first. However, once Cassie pushed it past the widest point, everything else went in smoothly, and only the wire to the remote remained dangling outside.

By now, Cassie’s nipples were already rigid and her breaths coming in short pants. She felt hot, but the calibration process was only beginning.

Once it was inserted, the app asked for a rating about the ‘fullness’ of the toy. Cassie had to admit, even if it was only medium, that additional one inch was enough to occupy almost seventy percent of her insides. She rated it a seven out of ten, and the app took some time to process her information.

Instead of the regular vibration stamina calibration that Cassie was expecting, the app changed its calibration process using her last session’s results.

The first buzz was low and lasted only ten seconds. Slightly disappointed by the lack of stimulation, Cassie quickly rated the intensity and waited for the next round. Each round, the intensity would increase, and Cassie was asked to rate the intensity level. Some rounds, they felt the same, and in other rounds, she could feel a drastic difference. The intensity of the vibrations did not increase gradually. Some were extremely strong, while others could barely be felt.

If she had to guess what this was, Cassie could only think of it as a user’s guide for averaging her sensitivity. It worked well as foreplay, and Cassie could feel her insides getting ready for more action. However, it remained frustrating when the app kept the vibration timing to only ten seconds.

After what felt like fifty rounds of questions, the app finally moved to the next calibration phase. This time, Cassie leered. It was finally beginning.

“Please do not remove the toy during the calibration progress. Kindly review the intensity changes each time and rate the vibration pattern to your liking from one to ten each round.”

It was finally happening.

There were a total of ten vibration patterns, and Cassie had no idea what to expect. All she knew was that some patterns were a turn off while others were good at building up the pressure in her stomach. For each pattern, Cassie was asked to rate the intensity with only three ratings - not strong, just right and too strong.

Honestly, there were only very few instances when the vibration was too strong for Cassie. Her pussy was made for pounding. Almost everything else felt like it was tickling her instead of bringing her to the edge.

For over the first five patterns, Cassie had to repeat many patterns because she couldn’t find a vibration intensity that met just right at the first go. Everything was so mild with the app, and it was getting annoying.

However, the moment she reached the just nice zone, the app would explore with a new pattern alternative, making Cassie repeat the process all over again. In the end, Cassie simply opted to spam the “not strong” option until the intensity was ramped up and stayed at the pattern for a while to determine if it was good or no good. If there were no new user input, the app would count sixty seconds and move to the new pattern.

Thankfully, Cassie was in the bathroom as the slick constantly ran down her thigh. She laid on her side, and it was starting to get uncomfortable, so Cassie shifted positions. Immediately after she sat up, the vibrator pressed hard onto a spot that made her scream and pissed all over.

Was that her bladder?

Once the pee gushed out, it wouldn’t stop until Cassie was twitching and everything stank in her tub. The vibrations were too strong, and Cassie hurriedly rated that it was too strong, hoping the app would get a hint and reduce the intensity for the next calibration.

It was odd cleaning her tub of pee while rating the vibrator’s performance, but Cassie somehow managed. If that wasn’t considered multitasking, she didn’t know what was. Moving around with the medium-sized bullet vibrator wasn’t easy. If anything, she was constantly reminded that something was there moving inside her.

After cleaning up, Cassie realised that she was already at the eighth pattern, and while the vibrations were alright, she wasn’t anywhere close to orgasming. When was this app going to get there?

Taking matters into her hands, Cassie deliberately rated the strong vibrations as “not strong” and hoped the app could take it up a notch.

Back at the headquarters of Wanda's Love Accessories Incorporation, CEO Wanda smirked. Someone was breaking the NNN challenge rule and seeking climax. The lady witch smiled and patted her unusual office plant, who hissed in return.

“Oh hush,” the modern witch chided her pitted tentacle monster with twinkling eyes. Rule breakers had to be punished, but she wasn’t going to be the one dishing them out. Karma would take care of it like it always did.

Warning: Next chapter will involve gore, death and possibly insects.
