Calibration Addict (3)

“Let’s see, step one. D******d the app?”

The first step was probably the simplest to follow, and Cassie scanned the QR code to d******d the Wanda app, signing in with her created account. The app was easy to access and use with a guided tutorial for first-timers. Cassie found herself staring at her profile page and filling up details about her height, weight, age and other regular things that she would be expected to fill for accounts like that.

However, that was where the ordinary experience ended. On Wanda’s app, a special survey section was designed to record her sexual habits and experience. Some of the questions felt slightly invasive to her privacy, and Cassie wondered if everything in here was compulsory.

Unfortunately, there was no backing out option once she started that section of the survey. With a heated blush, Cassie read through the questions and answered as honestly as she could. After all, she was a little curious about the assessment by the company’s sexual advisor.

“Ideal frequency for sex?”

Looking at the options, Cassie saw that it went from abstinence to slutty and decided to choose somewhere moderately slutty with a generous three times a week instead of daily. While that sounded rather tempting, it wasn’t realistic for Cassie, who had other commitments like school. Heck, she didn’t even want to delve into the customisable answers like twice to six times a day. Who even does that?

After answering all the sex-related questions, including a weird section about various kinks, tolerance and preferred toy sizes, with some of the terms that weirded Cassie out, she was glad the quiz was finally over.

Moving on to the app’s more exciting and practical part, Cassie grinned when a compulsory video played, explaining the toy calibration process.

“Welcome to Wanda’s calibration test!” the robotic voice greeted. “Kindly turn on your Bluetooth and all your Wanda toys for syncing. Press next to continue after you finish.”

Oh? Bluetooth syncing with multiple toys? Now they were talking. Cassie was rather impressed by the genuine claims of a highly advanced toy technology by the company. Maybe signing up for NNN challenge was a blessing after all. The vibrator set looked luxurious, unlike those cheap toys she watched in Jake’s secret pornography stash. They felt great and very skin-like in her hand, which could be controlled with a single phone app.

Most of the toys required charging, so Cassie synced them quickly to conserve the little battery power they had. The LED light was orange for some but red for most. It should give a yellowish-green light when fully charged.

After the app registered all her vibrators, it started to request individual testing. Here, Cassie had to press every button on the menu for the chosen toy, but thankfully, the test could happen while the toy was charging.

The process took several minutes to complete. Jake was right about it being time-consuming. Even the three yellow vibrators had to be calibrated individually. Cassie was now very familiar with the different modes, strengths and functions of every toy in her set. If only calculus were as easy as this, she would be a model student.

One thing that puzzled Cassie was how the strength of vibration for the toys without strength controllers could be adjusted according to a user’s sensitivity. The sensitivity calibration was a new feature that involved a little more than answering questions.

Referring to the manual for help with this part because the instructions in the app were unclear, Cassie found the section that explained physical testing for sensitivity.

After reading the instruction manual twice, Cassie blushed. Did she really have to use the toys to test for sensitivity on specific parts of her body? Wanda was really taking sexual pleasure research to the next level with this!

Nevertheless, Cassie thought it wouldn’t hurt to do it. However, she couldn’t do it with her clothes on. It would hinder the test result accuracy. The best place to do such a thing away from prying eyes was in the bathroom. The toys were designed to be waterproof for their use, and some required internal calibration. Working with lube was always messy, so it was best to do it in a place that she could clean up easily. What better place would that be if not the bathroom?

Shimmying her clothes article by article before she even reached the bathroom. Cassie brought along some lube, the smallest yellow vibrator and her phone. She didn’t need the instruction manual now that she knew what to do.

Closing the door impatiently behind her, the sophomore decided to take a quick shower before the practical calibration. Her heart pounded half in nervousness and the other half with excitement at doing something different. The shower was quick, and Cassie made sure to clean her privates properly. There was no point in risking an infection there. 

The lube was expertly designed by bedroom specialists. No wonder Wanda was such a successful company! They took into the urgency of users in the heat of the moment and included disinfecting properties, so sanitising toys before using was optional. Cassie was thoroughly impressed by their foresight. Not to mention, the lack of hot water sanitisation helped to preserve the condition of the soft rubber ‘skin’ texture on the toys. It was a win for all parties.

Following the instructions, Cassie switched on the small yellow vibrator but did not turn on the strength settings. According to the app, she had to place it on the indicated areas by the phone and hit the next button as fast as she felt movement from the gadget.

The first few areas were quite normal—places like her inner arm, knee, thighs and even collarbone for some reason. However, thereafter the places became strangely specific. For instance, the one about her tongue made Cassie wonder why that was important for calibrating her sensitivity. That was only the tip of the iceberg of the stranger locations.

Beep!

Cassie looked back to her phone after the calibration test for her nipple was done. However, the app now told her to apply a copious amount of lube for the next few final locations. This time, there were more instructions to follow and nothing as simple as indicating if she felt movement from the toy or not.

“Place the toy directly below your clitoris.”

The diagram showed a very graphic demonstration about placing the small toy above her vagina and sliding it upwards until the tip of the toy was resting against her clitoris and holding it there. Cassie had no idea why this was part of the calibration, but at least she was already naked. Nothing she couldn’t handle.

At the start of the calibration, the toy jerked a few times with varying intensity and asked for the user’s input to rate the strength level on a scale. Cassie had no idea how intense the toy could get because it didn’t seem to move as much as it did when it was still in the box. However, maybe she was more sensitive on her womanly parts that made the feeling linger for longer than she thought it would.

Buzz!

Muffling a slight scream and jerking a little, Cassie inhaled deeply after a particularly strong vibration wave. Yes, that felt like a ten to her.

After registering the user’s input, the app told Cassie to start inserting the toy after ensuring that it was well lubed. Finally, the real practical testing was happening, and Cassie was nervous.

Fingering herself a little, Cassie let out a soft moan at the slick sounds. She became this wet just from calibrating the vibrator used externally. The sophomore could only imagine how intense it could be once it was inside her.

Slowly, the yellow vibrator eased into her, and Cassie felt it filling her thirsty hole, clenching around the bullet like a parched puppy. The toy slid in smoothly without meeting resistance once, and Cassie followed the instructions, getting on her knees and palm to arch her back for a better angle, shoving the yellow bullet to nest right where she knew it would feel good.

Despite looking small, Cassie could still feel the weight of the vibrator resting at the pit of her stomach when she moved. It was a strange feeling, similar to getting a tampon in, especially with the cord attached to the hand-held controller, but Cassie tried to ignore it, pressing next to follow the new instructions.

This time, there was no instructions to follow or things to rate. Instead, a timer started, and the bullet vibrator started to move by itself. Cassie was about to remove it when the app warned her about removing it, or she would have to restart the calibration from the beginning all over again.

Not wanting to repeat the lengthy process, Cassie counted down with the timer. Thankfully, it lasted only sixty seconds, and the vibration strength wasn’t too intense. Maybe this was the app’s way of determining someone’s sexual stamina?

After sixty long seconds, the toy actually stopped moving inside her, but Cassie felt hot all over, and her nipples were perky. The appl blinked, and Cassie took some time to collect her thoughts to answer the question.

“On the scale of 1 to 100, how close were you to orgasming?”

Laughing slightly at the question, Cassie rolled her eyes and rated that a modest 5%. Something of that intensity wasn’t able to make her come, merely wet.

Immediately after she answered, the bullet vibrator started to buzz again, this time a little stronger than before, and the timer counted down for another minute. Cassie stopped laughing at once and found her lower mouth clenching at the new wave of pleasure. She was wet from the first round, but now, she was dripping. It wasn’t anywhere close to reaching an orgasm, but it certainly got her hot and bothered.

By the end of the torturous minute, the yellow vibrator stopped buzzing, and Cassie panted shallowly. Her hair was messy from all the squirming, and she shifted to a more comfortable position in her bathtub on her back instead after her knees started hurting. The new position pressed the toy deeper into her G spot, and this time, she gave it a rating of 20%.

One minute was definitely not enough to make anyone cum. Cassie wasn’t sure what the app intended to calibrate with this test, but she knew that she wanted more.

Granting her wish, the vibrator started buzzing loud enough for Cassie to hear some low drones from where she sat. The timer counted down for a minute again, and this time, Cassie had to stop herself from finger fucking where the vibrator resided. The buzzing on the inside created some sort of itch, and her hole repeatedly clenched as if begging for more. Sadly, the toy was all she had, and Cassie breathed deeply, trying to stay sane while holding her legs open and keeping an eye on her phone.

One minute passed, and when the toy stopped, Cassie could safely say that she was frustrated. This had to be the most torturous calibration procedure for anything! Giving it a quick rating at 60% now that all she wanted to do was cum, Cassie prayed that the vibrations would increase in the next wave.

However, she was wrong. If anything, the yellow vibrator barely moved now, only a little, creating an unbearable itch at the base of her stomach. Cassie groaned in frustration and seethed at how the app was playing with her.

The minute ended, and this time, Cassie rated the progress at 40%. Instead of becoming closer to the orgasm she wanted, it was becoming further. What kind of calibration was this? Were they trying to make her reach orgasm or not?

Over the next fifteen minutes, Cassie spent several minutes in toe-curling bliss with the vibrations inside her strong enough to be heard clearly and other moments where it barely moved. Her range varied from 20% to 95%, but as the time passed, the range became smaller ranging from 70% to 99%, because there was that one time she almost came over the edge. All she needed was a few more seconds, but the stupid timer had to end before it, ruining the experience for her.

By now, Cassie was a mess down there. However, all she wanted was a stupid release that never came. This app must be calibrating her sexual stamina by testing how many times they could push her near the edge and back off. She was tired, slightly sore and incredibly frustrated, almost to the point of tears and fucking herself with her fingers. However, she simply didn’t want to repeat the calibration process all over again.

The new round was slightly different from the rest. Instead of a sixty-second timer, Cassie saw that the program was now counting from one second. A new panel for orgasm count appeared beside it, and the toy did not seem to stop or slow. The sound was loud enough to be heard, and Cassie could almost feel the vibrations placing her hand across her abdomen.

Slick ran fast from her hole that trembled, and getting a grip became tricky in the bathtub with the small puddle of pleasure fluid. Cassie kept sliding and squirming to find a hold with her shaky legs, but her movements only stimulated better angles for the bullet inside her, bringing her closer to the edge and eventually, the sophomore was reduced to a moaning mess, clutching onto the edge of her tub for sanity.

Burning hot and squirming on the inside, Cassie could no longer tell if it was the vibrator, her love juice or the lube as everything mixed into a sticky mess. All she knew was the never-ending torture between too much and not enough. The heat from inside spread to her toes and to the palms of her hand. Everything was ablaze, but Cassie didn’t want it to end.

“Dammit!” she trembled like a newborn deer. “Just a little more…”

Vrrr! Vrrr!

For an unknown amount of time, the pressure kept building like a stubborn volcano, unwilling to erupt, clouding her mind until Cassie didn’t remember why she was here and what she was doing. She needed more!

As if knowing that Cassie was at her breaking point, the vibrator bullet increased its intensity and pushed Cassie over the edge. Her loud scream echoed through the bathroom wall and her nails pressed into the side of the porcelain tub painfully with her muscled spasming from the orgasm.

Relentlessly, the bullet vibrator did not slow as the app registered her first orgasm. Cassie felt her insides convulse violently as strength left her legs. Shaking as if she was possessed and eyes rolling to the back of her head, Cassie felt another wave of pleasure course through her blood, stopping her breath for a good few seconds before she came back to another torturous round of orgasm from the violent vibrations.

She could feel how she was losing control of her bladder, but there was nobody to care if she was rendered incontinent. She no longer had any control of her bodily functions as drool, sweat, pee and all sorts of fluids mixed in the tub. All Cassie knew was how the calibration wasn’t over, and the app continued counting orgasms until she stopped reacting and was left a twitching mess from all the fried nerves.

Even after the vibrator stopped, the slightest of movement in the air would cause Cassie to moan.

Disoriented and eight-limbed, Cassie finally pulled herself out of the tub to catch her breath and check the app.

“Congratulations! Calibration completed. You may retake the calibration test if the current results are inaccurate.”

Laughing hollowly at the advanced technology, Cassie couldn’t believe that her first mind-blowing orgasm wasn’t with Jake. Instead, it was the toy set she received after he encouraged them to sign up for NNN challenge. How ironic.

Oh, yes. She would definitely be back to recalibrate if she ever needed a replacement for Jake. Wanda lived up to its incredible reputation, and Cassie couldn’t wait to test calibration with the other toys in the set.
