Going to lectures will be really fun

Author's note: 67 % of you voted for Jess to go to her next lecture instead of going home and figuring out what happened with the app. Thank you for shaping the story, the "choose your adventure" style.

She had only a few minutes, and there was only one thing she could do to save the universe! I mean to save her boobs from being exposed to the whole lecture hall. And the one thing was to masturbate furiously in the bathroom stall. Fortunately, that was something she was really good at.

Her fingers were really going at it, and she was panting in no time. She just hoped it sounded like she was taking a really challenging shit.

She contemplated the odds of her clothing going fully transparent on orgasm, being also reversed. Maybe cumming quiskly would fix the issue immediately. At the same time, it could also lead to her dress completely disappearing in the middle of the campus. If she had her computer, she could try investigating the code, but she took only her tablet in her purse, so she was screwed.

Jess needed to make a decision and either go to the lecture now or go home. She was at the edge of cumming and she really needed it. She always made herself cum at the end, even if she was edging herself the whole evening, at the end she would get the orgasm and not just stop. This just felt wrong, and her pussy was buzzing.

Her sunglasses were still showing 92 %. It was an improvement, but when she looked at her chest, her dark nipples clearly contrasted under the dress.

Jess had an idea and pulled out the app. With a few clicks, she changed the colour of the fabric from white to black and turned it into a full dress. Luckily, she was allowed to do that, and even though there was a clear skin hue to her dress due to the transparency, it looked nothing like it did when the dress was white.

Her dainty hand opened the heavy door of the lecture room. She was late, but it looked like the professor was still organising his notes. Suzi and Dan were waving at her to join them. Jess smiled and went their direction.

"Aaaw, the white was cuter," Suzi said when Jess sat down next to her. Jess just gave her a look and said nothing.

Suzi was her best friend at the uni. She was a bookish-looking girl with messy hair, and she was even shorter than Jess. There weren't many girls at the faculty of informatics, so the two of them stuck together.

Jess watched the number on her smartwatch tick down again. Maybe going home wasn't such a bad idea. But she had two lectures today and a seminar, which had mandatory attendance. Also, being one of the few girls in these classes, people tend to notice when she is missing.

Her clit was insistently throbbing, making it hard to focus on the professor's droning about transformer architectures and diffusion.

The black fabric was 100 % better, but she was horrified about the future state of her clothing once the lecture ended in an hour. At least a few things now occurred to her. The AI must have gotten confused about the rules of opacity and transparency, or her prompt was wrong. This was obviously the one time when playing with your pussy and vibe coding at the same time was not a good idea. So instead of decreasing opacity with masturbation, it was increasing opacity. The clothing was also supposed to be able to recover on its own in five hours, so that was another error, or the issue was that the clothing's default state was to be transparent, so recovering meant going back to that transparency. That five-hour timeline resulted in 5% going down every 15 minutes.

Anything under 10 % was already embarrassingly transparent, so that meant she would need to manage to masturbate at a minimum every 30 minutes and given her experience from the bathroom, it was obvious the percentage wasn't gonna go up especially fast.

When it came to her current situation, she started the lecture at 92 %, which meant that in an hour, she would be at 72 %, at which point the smart fabric would make her functionally naked.

Jess tried playing with the fabric thickness, but found out that it had no notable visible effect on the transparency, and she could see that Suzi was observing her nervous actions curiously. At least Dan was focusing on the lecture instead of her. That might be just because he was gay. She knew from experience that there were always a dozen eyes on her whenever she was in class. Sometimes she really enjoyed the attention, especially when she was not wearing clothing that was hellbent on slowly disappearing in front of strangers.

She had the option of excusing herself to go to the bathroom, but that would still mean walking through a silent lecture hall in semi-transparent clothes.

Jess engaged gesture mode with her smartwatch to open apps on her smart glasses. After a few flicks of her wrist and circles with her fingers under the table, she was looking at the controls of her clit ring.

Her wrist slowly rotated to enable and increase vibrations. Her lips parted in response to feeling her needy button being flooded with a fresh wave of pleasure.

Jess squeezed her thighs. The number ticked up to 90 %. One minute of vibrations produced 1 % of opacity.

Both Suzi and Dan kept taking notes, but even though Jess had her notes out, she could barely hear what was being said. The vibrations kept pushing her quickly towards the edge, and she kept adjusting them to make sure she didn't go over.

She never liked cumming just from a vibrator on her clit, it somehow feels hollow. Using her own fingers is better, or having something filling her inside at the same time made it much better. Even with guys, it was amazing to have the ring buzzing while they were moving inside her. They felt like real studs for being able to get her to cum easily, and she got to enjoy the amazing orgasms. Win-win. Although her experience really was just her one boyfriend before she moved out to the uni, and one one-night stand that Suzi got her.

Jess should probably really stop thinking about sex if she wants to get through it, though. She came out of her reverie and noticed Suzi looking at her with suspicious eyes.

"I know what you are doing!" popped up as a message on her glasses.

"And I like it, good for you. You have to tell me later what you are using."

Jess just turned completely red; at least her clothing was now at 98 %.

Her pussy stayed at the edge of orgasm from the relentless buzzing. Her clit was stiff, and the ring was very effective.

With horror, she noticed the number go down to 97 %. It turned out that if the intensity of the vibrations wasn't at a certain level, it apparently didn't count.

She turned off the vibrations completely for a bit to calm down.

Suzi looked way too excited next to her. Was she getting turned on by her friend, obviously stimulating herself next to her, or did she just unlock some Suzi's kink?

For the rest of the hour, she kept balancing between her sanity and the clit ring's intensity. The minimum "allowed" strength was too high not to push her over at some point if she just kept it going.

Towards the end of the hour, it started trending down overall, and she was back where she started at 92 %. She could feel that her pussy was soaking and throbbing. It was fortunate that the smart fabric would not absorb any liquid, so she didn't have to worry about wet patches. However, her juices had to go somewhere, and she knew they would be on her seat when she stood up.

Going to lectures will be really fun today.
