After Casey had her breakfast and dressed, she stared at her underwear drawer and wondered if she should take a pair of panties with her just in case. The new rule was “skirts & dresses only. No panties, ever,” so she had to be prepared for an upskirt request at any time. She guessed it couldn’t hurt to be prepared, and they wouldn’t take up any space anyway. She couldn’t take the chance of putting them on, though. While she could pull off an upskirt pic in most situations without anyone noticing now, there was no way she could get away with taking her panties off first to do it if there were other people around. She bunched up a pair and stuffed them into the bottom of her bag anyway.

She arrived at Tech and parked her bike, then put on her running outfit. Riding a bike in a skirt with no underwear was one thing, but there was no way she could take the same risk when it came to the track so she slipped on her usual running shorts, hoping he wouldn’t be checking before classes began. If he did, she could quickly run to the locker room and remedy the situation.

It was a perfect morning and it felt good to be alone. After the run, she had just finished showering when the first ding arrived.

“upskirt”

There was no one else around, and Casey only had a towel around her, so without missing a beat she dropped the towel, spread her knees apart, took the shot and sent it.

Ding.

“Nice tits! thx”

Confused by what he meant, Casey checked the photo she had sent and realised she had accidentally angled the camera out a bit and had captured her whole nude body!

Oh God! He didn’t even ask for that and I sent it anyway!

Ding.

“Your mission today. Get someone to take a nude picture of you on campus. Text it to me sunset”

Casey felt her face get very hot, while at the same time, a chill went down her body. She guessed it was time to find out if her wannabe nudist excuse was going to hold water. Where could she go to get enough privacy so no one else would see, though? Maybe under the bleachers at morning teatime? At lunchtime, there would be students everywhere on the oval playing sport. Who would she ask?

She finished dressing just as Amelia walked in. Amelia! She would have to be her first candidate.

Who better than my best friend? She’ll understand.

“Morning, Amelia.”

“Morning, Casey. What’s happening?”

“Oh, nothing much.”

C’mon just do it, Casey, and get it over with.

“Listen, I have a kind of strange favour to ask…” Casey began.

“Oh?” Amelia enquired.

“This is going to sound kind of weird…”

“Yes?” Amelia further enquired.

“I mean really weird…”

“Just tell me already, Casey! The suspense is killing me!”

“Um... okay. I’ve been kinda thinking about becoming a nudist and I want to get some photos of me in day-to-day settings so I can see what I look like. Would you be willing to take a photo of me?”

Fuck! That sounded completely nuts! She’s going to think I’m insane!

“A nudist! What the fuck, Casey! Would your parents even allow it?” Amelia responded, clearly shocked.

“Um... I don’t know, yet,” Casey replied, “but I want some photos of me before I make the decision to ask them. Will you help me out?”

“Holy crap! Well, I guess so,” Amelia considered. “I don’t think we should do it in here, though. If we get caught taking photos in here, we’ll probably get expelled.”

“Oh no, not here. I was thinking under the bleachers at morning teatime?” Casey suggested.

“Under the bleachers? Are you crazy? Someone might see you.”

“I thought about that, but I think if we do it at morning teatime and make sure no one is looking, we should be okay. It will only take a minute or so.”

“Well, it’s your body and your reputation,” Amelia pointed out, “but if that’s what you want, I guess I can do it for you.”

“Oh, thank you, Amelia. This means a lot to me. Please don’t tell anyone about this.”

“Don’t worry. I won’t,” she replied. “I might be implicated as well if you get caught, so there’s no way I’ll ever tell anyone.”

Morning tea came around faster than Casey would have liked, and her heart was pounding as she quickly darted back to the locker room and put on the spare panties she had packed in her bag that morning. She was so glad now that she had decided to pack them. How could she explain to Amelia why she wasn’t wearing any when she stripped off in front of her? Then she considered that the wannabe nudist thing could kind of work for that as well. ‘The feeling of freedom’ or whatever. She made a mental note to remember that, in the future, if she had to strip off in front of someone and couldn’t put panties on beforehand for whatever reason. She felt weird having to think along these lines. As if stripping off in front of someone and pretending it was of her own accord wasn’t humiliating enough already without thinking about what clothes she should have on beforehand.

She located Amelia already at the bleachers, and after a quick look around they ducked underneath.

“Are you sure you really want to do this, Casey?” Amelia asked. “It’s not too late to back out.”

“No, I’m sure,” Casey replied. “This is the only way I can think of to find out if I really want to become a nudist.”

“Ok then… I guess you asked for it.”

Casey handed Amelia her phone, and after another quick look around, she quickly stripped off and took up a position with her back against the bleachers and her hands on her hips. She immediately felt completely awkward and wrong. The middle of campus during the day was no place anyone should be naked, least of all her.

Click.

“Do you want me to get a few more in case it doesn’t work out?” Amelia asked.

“Ok, sure!” Casey answered brightly, hoping her response sounded enthusiastic. Inwardly she was loathing every moment of being naked in front of her friend. She just wanted it over with as quickly as possible.

Click. Click.

“Ok done,” Amelia announced while handing Casey’s phone to her to check. Casey feigned interest for a moment to make sure the blackmailer would be satisfied with them, and then hurriedly gathered her clothes up and put them on again.

I actually managed to pull it off, and the wannabe nudist excuse totally worked!

She took some comfort in the thought, as humiliating as it was to have done such a thing at all.

Once Casey had finished dressing, they ventured out from under the bleachers.

“You two ladies. What are you doing there?”

It was campus security.

“Nothing,” replied Amelia. “We just needed to discuss something privately away from everyone else.”

Good old Amelia. That sounded totally plausible.

“Ok then. I hope you weren’t smoking under there were you?” the guard asked.

“Eww gross! As if we’d do anything like that. Disgusting habit,” Amelia replied.

“Ok…” he responded with some suspicion, obviously not quite believing her.

Casey suddenly realised she had minutes to get to class, and she still had her knickers on and no time to get back to the locker room to take them off and put them in her bag again. She had no choice but to go to class and try to figure out a way to get them off without anyone noticing, and that turned out to be easier said than done.

It was a Citizens Education class, commonly called “Cit Ed”, which was shared with students studying other trades. She took a seat in the back row, and then picked a moment during the lesson while everyone was writing, and the teacher’s attention was elsewhere.

Thank God I haven’t received an upskirt request yet.

Carefully and silently, she worked the panties off her hips and down to mid-thigh where they were still hidden by her skirt. So far so good.  Everyone was still concentrating on their work and not looking her way. Then she pretended to have an itch, and with one hand she quickly pulled them down and off. She then bunched them up into her hand and returned upright to stuff them into her pencil case. The only thing remaining was to put her phone onto her lap at the ready in case a text came.

Once it was done, she looked around nonchalantly to make sure she had gotten away with it unseen. To her dismay, there was a boy staring at her. She remembered his name as Greg. He slowly mouthed the words “what the fuck?” to her and kept staring at her with an aghast expression.

Casey suddenly felt her face get hot, and that cold chill rolled down her body again.

Oh God! He saw everything! What will I say if he questions me? Maybe he won’t ask? Oh please let him ignore me after class and go about his business. I don’t want to have to explain this to him, or anyone else for that matter. What if he does ask? I guess I’ll have to use the nudist excuse again. I can’t think of anything else. Oh God, I’m going crazy!

Vibrate.

It was an incoming text from you-know-who, and Greg was still staring at her. She started to panic. She needed him to look away fast. She tried pretending she was concentrating on her work while watching him in her peripheral vision so she could take the first opportunity to do what she had to do. At last, he finally looked away and she quickly took advantage of the moment to part her knees and take the shot, but he too must have noticed Casey’s movement and looked back while she still had her legs apart. Thankfully she already had the shot, and using her desk to shield her hands, managed to send the text just in time.

Class was dismissed, and she quickly gathered her things and headed towards the door before Greg had a chance to come and question her.

“Not so fast, Casey…”

Oh Crap!

“I saw what you did back there. What the fuck was that about?” Greg asked with a slight smirk.

He was a fairly rugged and rough-looking boy, but not ugly by any means. Definitely fit, with nice arms. Casey thought she had seen him with the football team a few times, and that he drove a nice car.

“I uhh… what do you mean?” Casey replied as if she had no idea what he was talking about.

“I saw you take your panties off and put them in your pencil case. Are you wearing no panties right now?”

Casey gave him a silent ‘shoosh’ gesture and took him aside.

“Look, it’s kind of a long story,” Casey started to explain, “but they were digging into me and making me feel uncomfortable.”

Oh, where did that excuse come from? That totally works!

“I’m not so sure about that,” Greg responded, still smirking. “Weren’t you the girl caught with nothing on from the waist down in the hallway the other day?”

“Yeah, same problem then. Then Cassandra pranked me by taking my skirt off me while I had my arms full. That was hardly my fault,” she replied.

“But wouldn’t you have learned from that experience?” he asked. “Why would you take that risk again so soon? There’s more to it, isn’t there?”

Fuck! I guess it’s time to break out the nudist excuse…

“Look if you must know,” she began, “I’ve been thinking about becoming a registered nudist, and I like to feel the freedom of wearing as little as possible sometimes, to imagine what it would be like.”

“No shit?” Greg responded as he took a step back to allow his eyes to take in her figure and imagine what she might look like naked. “Well, I think you’d make an awesome nudist. You should totally do it.”

Whew! That actually went well, even if he is thinking evil thoughts about me now.

She thought about adding something that would pave the way for her to ask him to be a future photographer on one of her missions, but she wasn’t sure she could handle being naked in front of a boy, especially one she didn’t know well. Still, he knew her fake secret now so she could approach him if necessary. In many ways, it would be easier than having to explain all this to someone new.

“Maybe I will one day,” Casey laughed, cringing inside at the thought of it. “But for now, can we keep this between you and me?”

“Sure thing. Okay, class awaits. Later,” Greg replied as he started to walk away. Suddenly he paused and turned back to her. “Say, are you doing anything Friday night? Would you like to grab a burger or something?”

Casey was slightly taken aback.

“Oh okay. I guess so.”

“Great! Okay let’s swap numbers and I’ll call or text you on Friday to figure out what time and whatever.”

They exchanged numbers and then quickly rushed off to their next classes.

Casey’s initial excitement at the thought of being asked on a date quickly left her as she remembered her current situation. She hoped it wouldn’t get in the way of having a bit of fun, at least just this once.

The rest of the day passed without incident, apart from two more upskirt texts to deal with. As she made her way to the bike rack, she wondered if there would be another stupid mission. As usual, the blackmailer seemed to know exactly when she finished classes for the day.

Ding.

“Where is the picture I asked for?”

Oh crap, she had almost forgotten. She quickly selected one of the pictures that Amelia had taken and texted it back.

Ding.

“Thank you. Next mission - set up a webcam at home and text the link to me”

Now, what is he going to make me do?

There was a webcam built into her laptop, but she had never used it before. She hoped it was working. After greeting her mother, she went to her room to study as she normally would. After a short search around her room, she managed to find the manual for her laptop and figure out how to set the webcam up to share it with friends.

Yeah right. “Friends…”

She texted back the link to him as requested. It was a few minutes before he replied again.

“The resolution isn’t great but it’ll have to do. Be online at 08:30 for further instructions.”

Casey’s heart was pounding again, wondering what she would have to do then, but on the plus side at least she didn’t have to ask someone to hold the camera for whatever this was going to be.

For now, she joined her parents for dinner, which turned out to be the standard meat and three vegs. There was the usual polite and frivolous banter between bites as they watched TV. Same old same old. In the back of her mind the whole time, though, Casey couldn’t shake the feeling of mounting dread or stop her heart from beating so hard at the thought of what those “further instructions” might be. She wondered if veins were visible on her forehead.

She was back in her room well before eight-thirty p.m. and took the precaution of locking her door behind her. Whatever she was going to be asked to do, she could be sure it wouldn't be pleasant, and it would almost certainly involve her naked body. She had the thought that she may as well just strip off already but then thought better of it.

Just wait and see first, Casey... You don’t want to look like an eager beaver.

Ding.

“I see you. Lie on your left side, on the bed, & face the camera. Keep your phone handy for further instructions”

Casey did as she was asked. She looked up to where her laptop was and wished she could at least see the man’s face at the other end instead of a blank screen. Then again, maybe she didn’t.

Ding.

“Remember I have all those email addresses. If you hesitate when I ask you to do something, I’ll send one of your pictures to ten people. If you refuse to do something I ask, I’ll send Monday’s video to everyone.”

Casey gulped and her heart sank. With such severe threats, she knew this wasn’t going to be good at all now. She remembered the photo of her when she was spread open between the two boys again and felt sick at the thought of anyone seeing it, especially not everyone she knew including her parents. She resolved that she would just do whatever he told her to and hope it would be over as quickly as possible.

Ding.

“Use your right hand to play with your tits”

Casey immediately obeyed. It was a fairly tame request compared to other things he had made her do lately.

Ding.

“Good. Keep it up while taking off your shirt & bra”

Casey immediately started following the request. To her horror, she was starting to feel that growing ache in her groin again.

Her shirt and bra were now off. Her skirt was now the only item of clothing remaining. She knew it would be next, but he had already seen everything she had anyway, so she wasn’t too concerned. Degraded and humiliated, yes. Concerned or surprised, no.

Ding

“Lift up your right knee”

Casey immediately followed the direction, but instinctively dropped her leg again when her skirt fell open to reveal her pantieless nether region. She tried again, smoothing the skirt out so it stayed in place better.

Ding.

“You hesitated. One upskirt picture just went to ten people. No covering!

Casey was sure her face just turned white, but she did her best not to show a reaction as she continued her task. At least her face wasn’t in that picture so she would be impossible to identify.

Ding.

“Lose the skirt and play with yourself”

Casey did as directed. Now she was completely naked and effectively masturbating for the man watching her. She was disgusted with herself for doing it, but she dared not do anything that might upset him further.

Ding.

“Sit on the bed and look at me. Then lay back, spread your legs as wide as you can and keep playing with your pussy.”

Casey obeyed without thinking after propping a pillow up against the wall. It was only once she was in the degrading position that she realised what she had just done. Her labia would probably be splayed with her legs so far apart! As she continued stroking her mound, her concern got the better of her and she allowed her fingers to check to see if she was open and creating too graphic a display. She hadn’t figured out what she might do if it was the case, though.

She tried touching the area as nonchalantly as possible. Her worst fears were realised. She was indeed open. To her further horror, an involuntary moan escaped her lips at her touch. She was so wet she could feel it on the outside of her vulva and all through her pubic hair.

My God Casey! Are you enjoying this? Are you actually a slut after all?

The now-familiar ache in her lower abdomen had returned with a vengeance and she could contain herself no more. Her primal, animal brain had taken over. She plunged several fingers inside herself at once and commenced the furious masturbation technique she had recently acquired. Her conscious brain knew he was watching all of this, but she was unable to stop herself. She felt the orgasm coming a mile off, and it was going to be a big one. Somehow, in the back of her mind somewhere, she retained enough sense to realise she would probably scream, as usual, and would need to muffle her cries, but she also knew she would be expected to maintain her position on her back with her legs wide open as she had been instructed. What could she do? At the last moment, she was able to think fast enough to use her free hand to grab her other pillow and put it hard over her face. She was just in time.

As the orgasm finally subsided, she took stock of her splayed position in front of the camera. Instinct told her to close her legs again, but she dared not until she was told to do so. Suddenly the ache in her abdomen returned even harder, and she found herself repeating the experience for the camera.

As she lay sweating and panting after her second orgasm, she could feel the tension building yet again, but she was physically exhausted now, so she made an effort to keep her hands away from herself while still remembering to keep her legs wide apart. She couldn’t decide if it was more difficult to resist the temptation to get off for him again or allow herself to go ahead and do it. She so desperately wanted to have another orgasm.

Ding.

“Good job! Your sister is safe for now. Smile & blow me a kiss, then you can go. Don’t forget Mark tomorrow”

Casey did as requested and blew a kiss to the camera with a smile. Then, without bothering to cover herself, she got up and shut down the webcam and the laptop.

She thought about what had just happened. She had royally disgraced herself and she hadn’t even been told to do the last part.

Maybe I am a slut after all?

It was a troubling thought, but exhaustion then took over, and she fell soundly asleep without even remembering to put her pyjamas on.
