Tense, followed by a startling discovery

I placed myself down on the edge of his desk as quietly as I could and spread my legs. My eyes were still fixated on the crowd as they listened so intently to his lecture. None of them seemed to be looking at me, which almost felt...disappointing, to an extent. Part of this collar that was so fun is that people could look at me, without seeing me. Having them not looking wasn't quite as fun, but I would still easily be able to enjoy being naked out in the open. At first I rested my hands on my knees. That feeling alone somehow made me feel that much more exposed, and I slowly began to spread my legs wide until everyone had an extremely good view of my cunt, adorned by a beautiful tuft of trimmed pubic hair. My clit throbbed with anticipation as it hung in the cool air and part of me wanted to just touch myself and cum over and over, but I wanted to savor it. I wasn't going to make a habit of doing this, or at least wasn't planning to right now.

Slowly I moved my hands up my body, taking in the feeling of my naked body without any interruption all the while looking at the crowd. As I passed over my nipples I had to clamp my mouth shut not to make a noise. Even though I desperately wanted to be as noisy as possible just for the freeing feeling it might give, I couldn't risk being found out, for so many reasons. Once my hands reached my neck I slowly ran them back down, this time taking care not to pass over the two hardened nubs on my chest. Settling my hands on the inside of my thighs, I slowly ran them up and finally made contact with my lower lips. Nectar instantly coated my hand as it ran over, up and down. Already I was feeling so close. Just as I slowly began to work in a finger, my heart sank.

During his lectures, Mr. Deacon rarely sat down, if ever. Yet for some inexplicable reason he sat down on the edge of his desk, right in between my legs, his back a mere inch from my soaked cunt, with currently my index buried deep inside. I completely froze as he sat there, asking some students questions. The risk and danger of it all brought me even closer, now simmering on the edge, but unable to do anything lest he noticed me. Somehow I managed to take out my finger and move my hand away without alerting him. For the rest of the next hour, he sat there, so painfully close to my naked body and if he wasn't talking, he'd have probably heard my heavy breathing. On occasion he'd reach over to something on his desk, just barely missing me. And even though I was clearly invisible to him, I could've sworn I saw him glance at my chest when he turned back. Perhaps he was looking at something behind me?

I obviously couldn't risk him hearing me do anything at this point and so I was left to sit there, drenched, painfully close to cumming. It felt like it dragged on for ages, but finally he stood up and declared the lecture to be over. I felt the relief wash over me. Part of me considered staying behind to finish off, but he'd definitely lock the door and leave me stuck here, naked for the rest of the day. With considerable effort, I got down from his desk, which now had a stain left behind, which was presumably invisible too, from the leaking I had done onto it. Looking at the exit, I realized getting out wouldn't be so easy. Tons of students were filtering out at the same time, and Mr. Deacon was ready to close the ranks. Grabbing my phone, I had little choice but to throw myself into the horde. With how cramped up everybody was, nobody would end up noticing a person too many, especially since I was on the smaller side compared to your average student.

Somehow I got out of the crowd without anyone being the wiser, nor any unfortunate touches to my body save for some people pressing up against my back. Happy to leave that experience behind me, I made my way to the toilets at great speed. Once inside, I first took a moment to check my phone. Shit. My work was calling me in because they are getting flooded. Quickly telling them I'd be there as soon as possible, I then moved over to the final stall. In all my haste I hadn't noticed but there were two big, grimy guys standing at the stall, eating sandwiches.

Fuck.

They finally got round to fixing that toilet. Maybe they hadn't yet found my clothes, I quietly tiptoed closer, overhearing their conversation.

"I can't believe someone stashed all of their clothes in there, even their underwear. And their shoes! Some students are real perverts."

"Yeah, though I hope she comes back to retrieve them, wouldn't mind catching a sneak peek of that."

The two men laughed as I felt disgusted. Admittedly, had I not had the collar I'd have have agreed I would be a complete pervert, but I wasn't. At least not in that sense. I did love plenty of naughty shit, but streaking like that was a bridge too far even for me. Not that it gave them any right to talk about lusting after me like that though, that still felt vile. Slowly I inched closer.

"So what do you think the dean is gonna do with those clothes?"

"I dunno man, she just took them with her and said she'd lock them up in her office."

Shit.

If that was true, no way would I get to them in time. At least the clothes didn't have any tags, so there was no way they'd be able to link them back to me. It still left me in a bad position. I couldn't go back to my dorm to change as I needed to get into the city to clock into work. At least my work uniform was there for me to change into, so as long as I could make it there, I'd be fine. Not having the luxury of waiting around any longer, I gathered what strength I had and moved outside, step by step. My legs were still feeling like jelly and occasionally I had to stop in order to not fall. I'd gotten so close and was still rather turned on. Maybe I could just...

I stopped myself as one of my hands reached down. Hearing the bus pull up in the distance, I needed to make a run for it, dashing toward the bus stop at a rapid pace, making my chest jiggle around rather uncomfortably each time one of my feet hit the pavement. Luckily I made it in time and managed to board the bus, as I had no way of hailing or alerting the bus driver once those doors closed.

The bus itself was relatively empty right now, much to my delight. This meant I picked out the first free seat and sat down, taking a moment to catch my breath. My ass felt uncomfortable on the hard leather, and I could feel how I was beginning to stick to it slightly, the sweat from my little sprint not making it any better. Even though my legs needed the rest, I decided to stand for a bit. I needed to shortly after anyways as more people began to load onto the bus. Most of the people were either older people or students from my college, one or two I even recognized. Having some time to kill, I felt my excitement beginning to flare back up again and that need to cum return. I tried my best to put it aside, thinking of other things, but couldn't get over the fact I was standing in the middle of a bus, completely naked.

I gently leaned up against one of the poles, and the feeling of the cold metal against my side gave me goosebumps and sent a shiver down my body. Every time the bus stopped, or even braked ever so slightly, I had to grab it to maintain my balance as my naked curves swayed, reminding me of my nakedness. That building excitement was getting closer again and I needed a release soon. Only two more stops till the mall where I worked.

I had to hold on.

All seats were full now, and some people had even begun standing. To be safe I moved to the back of the bus, where a couple was sitting, both college students. The guy wore a varsity jacket and seemed...flustered, he seemed to be trying to keep a straight face while at the same time clearly preoccupied with something. The girl seemed similarly busy. As my eye wandered down, I noticed. They were both getting busy down each other's pants. His hand was deep in her unbuttoned jeans while her hand was firmly around his cock, which he was daring enough to have out. Nobody else could see them here in the back, so apparently they felt confident enough to do this. Seeing this only turned me on even more and I tried to look away, turning my back to them.

Subconsciously, one of my hands had drifted down and was gently rubbing my slit, as a soft moan escaped me. Due to how busy the bus was, nobody would be any the wiser as I felt myself give in to my desire. Just as I felt another climax coming, the bus made a surprisingly sharp turn, knocking me back.

The orgasm hit me at that point as I felt a sensation of pleasure wash over me. My leg muscles twitched heavily as my entire body felt like it was burning up. For a moment all I could think about was that pleasure and that strange sensation between my legs. I looked down and felt horrified as I saw that despite being able to catch myself, the guy's tip had pierced my entrance, going inside just enough to feel amazing. The moment I saw this I pulled off, just barely able to stand and made my way of the bus, realizing this was my stop. Just as I walked out the door I looked back to see the girl mortified as the guy came all over her hand.

I stumbled off and sat down on the bench at the bus stop.

I needed to catch my breath.
