The Science Project, or the time I accidentally masturbated in front of the class [f+] [sci-fi] [female masturbation] [teacher/student] [bondage] [consent gray area] [some other crazy shit]

Tiffany walked up to the front of the classroom, science project in hand.

“Thank you,” Mr Sumner said, “For volunteering to present first. Not many students are as brave as you are.”

“It’s my pleasure,” the mousy girl said, “I put a lot of effort into this, and it paid off. It works! I just need to hook it up to your projector, …and, a volunteer from the class?”

I raised my hand. Tiffany was my best friend. Asking for a volunteer was just a formality. Of course she picked me. I’d even helped her test it, knew what to expect.

“Thank you, Theresa,” Mr Sumner said, rolling his eyes at cliquishness. But it’s not like anyone else volunteered.

“Now, please sit here,” Tiffany said to me. The chair was in front of the classroom but facing sideways, towards the teacher’s desk, so I could see both the screen and my classmates. Tiffany arranged the device on my head, explaining, “And then, we just place the headband like so.” In my brain, I felt a tingle as she got it into the exact position.

“Sewed into the fabric of the headband are several brainwave sensors,” Tiffany said to the class. She pointed to the snake of wires coming out of the back. “And these,” she said, “Connect to the mainboard here, where the processor is.” She flipped several switches and turned a dial, watching the numbers change on a small screen. As she tuned the machine, the tingle softened and became a gentle hum.

“And so,” Tiffany said, “As I get this aligned, you all can see the image starting to come into focus on the screen.”

I turned to look myself, saw an indistinct blotchy brown smear, a few hints at structure in the image, but shifting rapidly, changing in time with Tiffany’s adjustments.

“It’s there, but still distorted.” She adjusted another dial. The hum in my brain changed in timbre, something different from any of our tests, but the picture on the screen was clearer than she’d ever gotten it before.

“Yes, that’s it!” Tiffany exclaimed. “Now, Theresa, I want you to picture in your mind’s eye a small island. The island has pristine beaches surrounding a beautiful forest, a mountain with a majestic waterfall in the center. There’s animals on the island, deer, tropical birds, a unicorn.”

The image on screen began coalescing into what Tiffany was describing. Mr Sumner was watching closely, but our fellow students were barely paying any attention. I scanned the room, saw people talking, reading their phones, napping. Only a few people were looking at the screen, and mostly their gazes were vacant, disconnected. I felt bad for Tiffany, she’d put a lot of effort into this project, but hardly anybody seemed to care.

“Thank you, Theresa,” Tiffany continued, “Please just keep that image in your head, if you can.” She turned to the class, oblivious to their inattention. “What you are seeing on the screen is being projected directly from Theresa’s mind. You are literally seeing her thoughts.” The tingle from the machine’s connection to my brain was still there, humming along pleasantly, just slightly too noticeable to ignore.

“Bullshit,” Caleb called out. He was always a rude jerk, but at least he was listening.

“Caleb,” Mr Sumner said sternly, “Be respectful.”

“But Mr Sumner,” Caleb protested, “This is just a shitty video. All Tiffany’s got to do is watch the video ahead of time, then call it out to us a few seconds before we see it. It’s an old parlor trick.”

“Ok, Caleb,” Tiffany said. She always kept her cool. “Tell Theresa what to imagine, then.”

“Shit, I don’t now,” he said, “Make the sky purple or something.”

The class got a touch quieter. I turned to look, saw that the sky was purple.

“Make the mountain explode,” the goofball Taki called out, “Like a volcano.”

I pictured the mountain bursting with rainbow-colored lava, and there was some quiet laughter and at least one “whoa!”

“Give it a dragon,” Emery said. I put a big red Chinese-style dragon soaring through the air.

Meanwhile, the amusing little tingle had spread from my brain and out into my body. I could feel it in my fingers, in my toes. Like a tickle, but better. I made a note to ask Tiffany about that afterwards.

“You can see,” Tiffany said, cutting off a dozen more requests with a loud, piercing tone, happy to have caught the room’s spotlight, “That having your mind’s eye visualized like this allows the participant to develop more and more complex mental pictures than they otherwise could. Seeing — literally seeing — what you’re imagining allows you to reinforce the constructed image, building intricate hypothetical models. Theresa can continue adding to the scene as we see it, but she can also do more. Up til now, we’ve been looking at this island from a bird’s eye view.” She turned to me. “Theresa, can you please take a walk down the beach?”

“This is truly impressive, Tiffany,” Mr Sumner said.

The class gasped as the image shifted and they saw a version of me walking through this crazy vision we were collectively building. The me on the screen was idealized, my dark hair perfectly cut and shaped, my body just a touch taller, slenderer, sexier. It — me — I — was wearing a flowing yellow dress, fluttering in the breeze as I walked through the sand with a delicate step, leaving a trail of soft footprints. It was how I’d been trying (and failing) to draw my self-portrait in art class last week.

I had the me on screen turn inland, walk off the beach and through the foliage, and then find a unicorn. I made the unicorn’s hair burst with flowing reds and golds as I petted it.

But as I did this, the fuzzy tingle seemed to be growing stronger. Tiffany and I had tested this many times, and the humming sensation was always there. But it usually was nothing more than a tiny white noise that I’d ignored. Right now, though, I was feeling the buzzing tickle throughout my body, especially in my, err… well, erogenous areas. I was becoming aroused. But I clenched my teeth and hid it. I didn’t want to interrupt Tiffany’s presentation, and soon I’d be back at my desk anyway.

“Now the really crazy part,” Tiffany was saying, “Comes when you imagine other people. I need another volunteer.”

Every hand in the class went up.

“Thank you, Caleb.” Tiffany turned to me. “Theresa, can you please place Caleb into your visualizations?”

I shifted in my seat, squeezing my legs together to stifle the building heat I felt there. I smiled and nodded at Tiffany, pretending everything was normal.

On screen, I walked through a thicket and emerged by a small natural pool. And splashing in the water was Caleb. Or at least a version of him. The class giggled.

Now, Caleb’s not just annoying, he’s also awkward and funny-looking. Not the type of guy I’d ever been attracted to. But the version of Caleb on screen? It was clearly still him, but a far more handsome version. His awkwardness was gone, his facial features more rugged, his pose more confident. And he was built, good lord was he built, every muscle defined, wearing nothing but board shorts.

Caleb in real life was blushing, hiding his head in shame. I should have felt bad for the guy, but I was too distracted by trying to fix the picture on screen, and by what was going on in my own body. I tried to visualize a more realistic Caleb, but every change just ended up focusing the picture in on him more and more, until the embarrassingly sexy Caleb was filling the screen. The giggles became laughter.

“Girls, please,” Mr Sumner said, “Don’t make fun. Picture something else.”

“Like me!” Emery shouted.

Emery was a spunky girl who everyone liked. She had a great energy, was cool without trying. More popular than the popular kids because she just didn’t care, was only ever positive and upbeat. But on screen, she, too, got the sexed-up treatment. Bigger tits, fuller lips, scandalous bikini. Worse, she was wrapped around Caleb in an passionately intense embrace, her lips locked to his while she ground her crotch on his thigh. Their hands were all over each other, and they were clearly moments away from fucking.

I don’t think of Emery that way either, but the tingle was in my nipples, on my clit, and it was making me incredibly horny. And the problem was, it felt good. Real good. I knew my cheeks were red, I knew I was totally wet. Probably anyone looking at me could tell, the way I was panting. Probably everyone already knew, seeing what I was picturing on the screen.

My mental picture of Caleb and Emery had… well, now they were totally fucking. Going at it with crazy passion.

Real life Emery stared, on the verge of tears as she watched a version of herself ride Caleb’s cock, suck him off, get taken from behind, begging for more. Climax after climax as Caleb filled her with his cum, sprayed it on her face, on her tits.

I was embarrassed for them. But this was in my own head, part of me wanted to stop it, but what I really wanted was to see them fuck even harder. I could barely keep my gaze focused, keep my lips together, keep my legs together.

“Theresa,” Tiffany hissed in my ear, “Stop this! What are you doing? You’re ruining my presentation!”

“I can’t,” I moaned through clenched teeth.

“Tiffany,” Mr Sumner stood up from his desk, standing tall, looking mighty mad, “Turn this off! Now!”

“You don’t understand,” she screeched, staring at the dials aghast, “I can’t just turn it off like all-of-a-sudden. It’s connected directly to her mind. Powering it down too quick will give her brain damage!”

“Then as quickly as you can,” he barked. Damn, he looked good when he was mad. That square jaw, broad shoulders. His outfit was pure professional, of course, but no pants could hide an ass that hot.

The screen flashed. Caleb and Emery were gone. Everyone breathed a sigh of relief. Everyone but me, that was, because I knew what was coming.

The island was completely gone. Replaced with a classroom. This classroom. It was dark, and empty. No, not quite empty. There was Mr Sumner.

The real Mr Sumner froze in place, his eyes going wide. “Oh no,” he muttered, “No no no…”

The Mr Sumner in my mind’s eye was an exact copy of the real version. But he was standing over the sexy version of myself. She was now completely naked, bound in tight ropes, arms pinned to her — my — sides, gag in my mouth, suspended from the ceiling like a marionette. I swung back and forth, moaning in pleasure as Mr Sumner smacked my tits, fondled my pussy.

The class was dead silent, everyone staring at the screen.

In my real body, the tingle was not just tickling my clit, it was positively massaging it. The pleasure was arresting. I was so fucking horny, I could not sit still in my seat, and was wiggling and squirming. My chest was heaving, and I’m pretty sure I was drooling, although when I managed to look down to check, I saw my hand fondling my breasts, tweaking nipples which stood prominent through my shirt.

On screen, Mr Sumner had adjusted my position, and now I was hanging, bent over, my ass high in the air, legs forced apart. His hands had grown more aggressive, were violating my pussy and ass. And I loved it, was climaxing continuously, pleading for more.

My real-life hand slipped down into my pants, and I couldn’t help myself, the image on screen was such a turn-on. I was fingering myself in front of the class, not caring that they could see. The tingle was imperious, sending shocks of pleasure throughout my body, making me convulse. The crotch of my yoga pants was soaked through, and I thrust my hips onto my hand, masturbating at a furious tempo.

My moans kept pace with what was happening on the screen, where Mr Sumner had pulled from his pants an unlikely large erection. He was slapping it against my swollen wet pussy and taut asshole, a look of pure need on my face.

“Tiffany…” the real Mr Sumner growled low, almost a whimper, his face beet red.

The imaginary Mr Sumner’s face took on the same complexion, except his was from lust. His giant cock began spurting an impossible amount of cum, and virtual me was getting covered with his seed. But it wasn’t a realistic orgasm, it was my horny hypersexual fantasy we were watching, of course. So despite all the cum, he was nowhere near finished. Rather, he’d only begun shoving his dick in my bound ass.

The real Mr Sumner and I looked at each other. I can’t tell you the meaning of his look, but whatever it meant, his eye contact just made me hotter.

“It’s not stopping!” Tiffany exclaimed as she desperately tweaked the dials and switches.

She flipped one more switch and instantly, the tingle was no longer a warm hum — it was a full on pleasure avalanche. My real body shuddered and shook, unprepared for such a powerful thrill. I didn’t even know my body could feel these things, I didn’t know I could so utterly lose myself to sexual pleasure.

The tiny part of my mind which remained functional noticed an entire classroom full of arousal — people shifting in their seats, pupils dilated, hands suspiciously near crotches, breaths coming in sharp and quick. Everyone’s gaze was fixed to the screen, where Mr Sumner and his giant cock fucked my ass like a steam locomotive while I wailed in pleasure, straining at my bonds.

The scene on screen had been growing more and more vivid, the picture clearer, brighter, more detailed.

His dick had never stopped spraying cum, and his sticky semen gushed from my ass with each of his thrusts, pouring down my legs, mixing with the fluid flowing from my pussy. Each time I felt his shaft penetrate me, it was another climax. My every muscle was clenched, my toes splayed, back arched, eyes rolled back in my head. Drool spilled out around my gag, pooling on the ground beneath me as I swung in the air, getting fucked by my teacher.

Then he pulled his cock out from me, adjusted my position again. I was hanging face up, head right at his crotch level. I saw him take position above me, looking down at me, eyes hungry. He removed my gag while his cock swung in my face, spraying cum in my eyes, in my hair.

Then he tilted my head back, and I opened my lips automatically to admit his erection. He shoved his full length into my mouth and down my neck in one steady motion, his cum spraying from my nose as I gagged and sputtered. His balls filled my vision as they bounced against my cheeks. He fucked my throat, his cock visibly stretching my neck with each thrust, as he grabbed and slapped my tits. I couldn’t breathe, but it was fantasy, I didn’t need to, and I got off on being choked by his cock.

Suddenly there was a second Mr Sumner, identical to the first, stepping up between my legs, pushing them back, wider and wider. He pulled out another rope and tied my knees to my shoulders. No way was I this flexible in real life, but here I was, body contorted to be fully accessible, pussy completely exposed and vulnerable, loving every second of it.

The second Mr Sumner pulled out his own enormous cock and slapped it against my abused crotch, then skewered me, my pussy forced to its limits to accept his impossibly thick shaft. I didn’t know it was possible, but I was somehow climaxing even harder, lost in a rapture of sexual euphoria.

I was subjected to an impossibly thorough domination, humiliated in front of my classmates, savaged by my teacher, and craving more more more.

“Theresa!” I heard Tiffany say. “Oh my god, wake up, please, tell me you’re ok!”

She was shaking my shoulder. I wanted to sleep, but Tiffany was being really quite annoying.

“Stop it,” I muttered.

“Oh, thank heavens,” she said.

“What?” I said crankily, opening my eyes. What was that…? Eww. I’d been drooling. I wiped my face with the back of my hand. How long had I been asleep?

I looked around, saw an entire classroom of students plus Mr Sumner staring at me. Why was I sitting in front of… realization hit. Oh fuck. I shriveled. Looked down, saw a huge wet spot in the crotch of my pants. Oh no no no.

“Theresa, are you with us?” Mr Sumner asked.

“Yes,” I whispered, not able to make eye contact with him, with anyone.

“Tiffany, Theresa,” he said, “Dean’s office, now!”

## ## ##

Sitting on the chairs lined up outside the dean’s office, Theresa whispered to me, “What the fuck was that?”

“You know that tingling sensation?”

“Oh fuck,” she said, eyes going wide in realization.

“Yeah,” I said, “Oh fuck indeed.”

“I’m so sorry,” she whispered, “I’ll fix it. I’ll make it work better. I have some ideas–”

“Tiffany,” I said, “The whole class, including the teacher, just watched me jill myself off while fantasizing about being dominated by said teacher. ‘Sorry’ doesn’t exactly cut it.”

“Are you mad?”

I considered. I felt like I should be mad. Like anyone else would’ve been. But, no… I wasn’t mad. Why?

“I don’t think so,” I said, “I think, maybe, something oddly freeing about getting all that sexual tension off my chest. Like… I have no more secrets now. It’s… liberating.”

“I… um… are you sure?” she said.

“What are people going to say? That I’ve got the hots for Mr Sumner? Half the girls at this school do, a decent number of the guys, too,” I said, “Plus, I’m pretty sure I saw him getting hard. Which is fucked up but amazing.”

“No!” Tiffany sounded scandalized.

“Yes!” I said sarcastically, “He’ll probably have a morally confusing boner for weeks.”

We sat in silence for a moment. Then I said, “But I should probably transfer out of his class, don’t you think?”

Tiffany giggled, then burst into a fit laughter. It really took her, and she nearly fell out of her seat she was laughing so hard. It was contagious, I couldn’t help but see the absurdity of it all. I was laughing with her.

Tiffany had to wipe away tears, she ended up laughing so hard. Then she said, “Weird the tingle never did that to me. I think I know what I did wrong though, how to adjust it so it won’t happen again.”

“That’s great,” I said, “But don’t. It’s perfect just how it is.” I gave her a knowing grin.

She recoiled. “First off,” she said, “Gross. I’m not helping you masturbate. But second off… really?”

“Yes, really, you prude,” I made a gesture, stroking an imaginary penis, “And guess what? You already did. I don’t think you realize how good that orgasm was. I’m coming over tonight. I want at least an hour on the device.”

“But…” she protested, “An hour? You’ll rub yourself raw.”

“I’ll bring lube.”

## ## ##

Later that night, Tiffany’s mom opened the door for me.

“She’s been up in her room all night,” she said to me, “She said she had to finish her science project. But I thought you helped her present it today?”

“Yeah, we did,” I said, walking up the stairs, leaving the question unanswered.

I walked into Tiffany’s room, closing the door behind me, and saw my petite friend in a daze on her desk chair. The device’s headband was in place, and she was down to her bra and panties, a vibrating wand shoved between the fabric and her pussy.

On the computer screen in front of her was a scene of debauchery. Tiffany never talked about who she was attracted to, or wanted to date, or anything, so I watched, curious. Tiffany was there, but it was an animal version of her. She was some sort of sexy fox, in the middle of some sort of gangbang with other sexy animals. My eyes went wide. She was on all fours, dicks in her mouth and ass, getting eaten out by a leopard girl underneath her. More animal people surrounded them, boys stroking each other off, taking turns fucking Tiffany and the leopard.

“I always knew you were a nasty slut,” I said.

Tiffany looked up at me, her gaze dreamy, slow to focus. “Oh, hi Theresa.”

I kept watching, transfixed, and I began to realize that I recognized some of the animals. They were students from our school rendered as wolves, bears, tigers. The view adjusted and I realized I was the leopard girl. I was being ridden by a horse that resembled Caleb as my tongue lapped away at Tiffany’s pussy.

“You sick furry fuck,” I hissed, “Leave me out of this.”

She giggled and blew me a kiss.

She was never this way, it was like she was drunk. I shook my head. “What, do you have a thing for me or something?”

“It’s not like that,” she said, voice slurred, “It wasn’t on purpose. I just couldn’t stop thinking about how hot your whole things this morning was, and then, I guess, next thing I knew, there you were. Then you crawled underneath me. Sorry. I guess.”

“Give me a turn,” I said, “As as long as we’re doing this, I’m going to imagine you, but with a huge swinging dick between your legs, giving me a ruthless fucking.”

“Oh,” Tiffany’s eyes popped into focus and she fished around her desk, looking for something. “I forgot. I had spare parts. Made another headband. Now the thing’s multiplayer.” She proudly held out a second sensor band.

I felt myself getting wet just looking at the thing. This was going to be a fun night.
