The Presentations

The nervous chatter of a full classroom is oddly calming to you. It's nice to know that you aren't part of the people presenting today, but you still feel nervous -- or is it excitement? Around the lecture hall, there are lots of people, some of them you recognize. The attraction of being at university still hasn't been lost on you, being on your own time is amazing.

Across the lecture hall, you spot out people you recognize. Aside from Haley and Brianna, who you walked in with, you notice Lola, who you met at the same uni club that you met Brianna at, and Katie, a cute Asian girl that you've seen around.

The three of you take your seats, and the lecturer starts up the class, announcing the first presenter: Brianna.

Brianna blushes a little, "Wish me luck guys." You and Haley wish her the best of luck. Before she fully leaves you 'jokingly' say "Just imagine everyone naked!" with a little chuckle. She laughs nervously, "I don't think that'll make me less nervous..." and she walks down the stairs to the presenting area. As she fiddles around with the slides, you think about a few ways you could mess with her presentation. With any luck, the rest of these poor students will get to do their presentations later. But hey, you aren't trying to be a hero, you're trying to get off.

She starts presenting, her presentation is titled: Marine Biology; the Dangers of Dredging.

You try something new: planting an idea in her head. Riffing off the joke you said earlier, you imagine that Brianna is imagining everyone naked. It doesn't seem to have any effect. You frown. She probably just had a fleeting thought. You try again. You see everyone as if they were completely naked, with life-like accuracy. You project the thought towards her.

"As you can see in this image, dredging can have disastrous-- Aah!" Brianna stops abruptly in her tracks. You smile with satisfaction, clearly your idea worked.

"Everything okay, Brianna?" The lecturer asks light-heartedly.

Brianna's eyes scan the crowd feverishly, she looks shocked, and partly aroused. Her cheeks are shamefully beetroot-red, and she looks at her shoes. "Uh, uhm, yes, sorry, ma'am." She looks up at the lecturer to apologize, and quickly looks away, blushing. She stumbles through a sentence, occasionally rubbing her eyes in disbelief, before eventually doing her best to continue with the presentation.

That was fun, but you aren't done. Time to mess with her outfit directly. Brianna is wearing a knee length brown dress with a white top underneath. Whatever you do, you'll have to be cautious to avoid suspicion (not that anyone would guess what is really going on). You want to try something, but you don't want to be too obvious; just obvious enough that people would recognize it, but not so much that it's unrealistic.

An idea strikes you. You direct your thoughts towards Brianna. Your shirt is no longer long sleeve, nobody notices, not even you. As predicted, your thought becomes reality, it seems that only you have noticed the change, but even you struggle to remember her ever wearing a long sleeve shirt. Good, the plan will work.

Directing your thoughts again, you press onward, You aren't wearing a shirt, you didn't put one on today. Nobody notices except for you. You smile satisfied as the thought comes into effect. Brianna squeaks softly as her shoulders are revealed, then keeps talking. Her brown dress has thin straps that go over her shoulders, so her shoulders are quite alarmingly bare. You feel a tightness in your pants. Brianna looks at you and blushes. Oh, you hastily add on, you no longer see everyone as naked. Heat rises in your cheeks as you imagine what Brianna must have been seeing.

Brianna touches her shoulders consciously as she presents. You can sense that her presentation is well past it's halfway point, you have to do something.

A loose thread on your dress is caught on the presentation lectern, it unravels as you move around, you and the lecturer don't notice.

Lo-and-behold, Brianna keeps talking as if nothing has happened, but a thread of her dress has clearly caught on a loose nail on the lectern. As she talks you watch the hem of her dress rise, hypnotized by the action. It creeps up her knee, revealing first her lower thigh. Already so much of her leg is exposed. Brianna paces as she talks, which is all the best for you. She paces, and the hem unravels, layer by layer. Next, her mid-thigh, taking the brown dress from a conservative sundress to a provocative night-club dress.

You realize something and hastily think, If anyone notices what's happening to Brianna's dress, they don't say anything to alert her or the lecturer.

Her dress continues to rise, to her upper-thigh. Her legs are almost entirely exposed now. If you look closely, you can almost see the soft lump of the bottom of her pussy under her underwear. From the slight flashes you can see, her underwear is dark blue. You glance around at the other students in the lecture hall, many of them have a pink flush on their face, clearly noticing their classmates' predicament - some of them even seem to be enjoying it.

Without meaning too, an intrusive thought finds its way into your mind, The fabric on her dress's straps starts wearing down. Before the presentation is up, it will fall off her. You grin at the brilliance of your subconscious. You allow Brianna to start noticing the changes in her outfit, but only slowly.

As she keeps talking and walking around, the dress unravels up to her waist, revealing her panty-clad white ass. It rocks hypnotically as she walks around. Brianna blushes as she starts to realize what's going on. Don't stop presenting until you're done, You think quickly. This needs to happen to its completion. Brianna keeps touching idly at her bare shoulders, not realizing the effect it's having on her dress.

Blushing, Brianna hides behind the lectern. It's to be expected, she's clearly embarrassed at what's going on, but there's something in her brain (you) telling her to finish her presentation. As she talks, unable to pace, the rate of her touching her shoulders increases.

You project your thoughts to the lecturer, Brianna shouldn't be standing behind the lectern, it's bad presenting. Let her know.

"Brianna, please don't stand behind the lectern. It's bad presenting."

Brianna sputters, flabbergasted at what the lecturer is suggesting. She looks down at her body, quickly covering her panties with her hands the best that she can. "Seriously?!?"

The lecturer frowns, "Yes, Brianna, seriously. Unless you want to tank your grade, we covered this in last weeks presentation-prep lecture."

Brianna blushes profusely, and walks out from behind the lectern. To your pleasant surprise, the thread managed to keep unraveling while she was back there, and her stomach is completely exposed, it looks like she's wearing a crop top and nothing else. She squirms as she finishes up her presentation, pacing faster than usual and stumbling over her words.

"And uh, Smith et al. say that this has a serious effect on the trout population," she continues rambling on, pacing.

But the more she paces, the more the dress unravels. You can hear in the corner of your periphery some students giggling. Looking over, you can see some students with their phones out, capturing Brianna's humiliation and sharing it with the world. The straps on her dress are becoming dangerously thin, only holding on by a few threads themselves. With no interference from you, they will fall soon, exposing her to everyone, naked as the day she was born (plus the panties, of course).

"And that's why we should ban dredging, basically, yeah" Brianna rushes.

"Sorry, could you repeat that?" The lecturer prompts.

Brianna huffs, frustated and humiliated. She brushes her shoulders, "I said, that's why we should ban-- AAAH!"

She squeals as the shoulder straps on her dress give way, dropping the pitiful remains of her dress around her ankles. Her boobs are completely bare, her nipples pointed in the air-conditioned air. All in a moment, she throws her hands across her body and the students start talking amongst themselves, one part concerned, one part entertained.

Brianna screams, her face the reddest it has been all day, and runs for the door.

The door is locked, You quickly command without even thinking.

Brianna tries the door, her boobs jiggling with the force of her arms, "What the HELL!? Why is this locked??!?" Brianna is frantic with humiliation, a few snickers rise from the audience. Nobody help her, you throw out the thought to the room, hoping it will work, you feel your pants getting wet at her humiliation.

She runs up the stairs, desperately trying to cover every inch of her exposed bare white skin, her shoulder length hair doing nothing to help her humility.

Someone grab her panties and pull them down. You see if the command will work, and miraculously, it does! A boy from the crowd jerks out his arm and grabs the back of her panties, stopping her run in her tracks. Brianna falls to the ground, catching herself with her forearms, her bare ass falling out of her underwear. Scrambling and humiliated, she runs naked up the stairs.

A few people laugh. You hear someone wolf whistle and say, "Way to go, Brianna!"

A few more whispers, "I didn't think she was such an exhibitionist." "Damn, she's hot."

"Nice ass, girl!"

The back door of the lecture hall swings open as Brianna sprints out into the halls, spreading her humiliation across campus. You can only imagine how sexy she must look, running completely naked through school, laughed at and recorded by her peers. You'll definitely be looking up the videos on Insta later.

The lecturer puts up their hand, silencing the clamoring students, "Right! Someone go help her, and we will continue with our presentations in the meantime. We are already a week behind schedule, we cannot afford to postpone these any longer, no matter what!"

The lecturer continues, "Next up is..."
