It seemed to work, however, and from the forty-five degree angle I was filming from, I had a perfect view of his tongue moistening her entrance while her growing arousal lubricated her tight tunnel from the inside, preparing her for the intercourse that made up a significant portion of her presentation grade. She soon moaned her readiness and bent over, offering herself to the first presenter who was still monologuing about the agricultural practices of feudal Europe.
She gave a small coo of pleasure as the tip of his cock parted her sensitive labia and slid smoothly into her depths. Glad that it wasn't her turn to speak yet, the redhead basked in the sensation of primal fullness for a second before her partner slowly withdrew. He too was clearly enjoying the sensation of their copulation as her soft folds pulled and tugged at him, and when he concluded his portion of the presentation I could hear a bit of a quaver in his voice from the waves of pleasure emanating from his dick.
As much as she was enjoying herself, however, the redhead was now looking with no small amount of trepidation at her other partner's cock as he picked up where the first presenter left off. His dick was hanging fully erect in her face, eager and ready for the slick stimulation of her mouth, but it was clear that, whether she disliked him or just hated giving blowjobs, the girl really wasn't looking forward to what she was about to do. Still, her grade depended on it, and so she sucked it up and prepared to dive in.
I didn't enjoying seeing her discomfort, so I decided to make it a bit easier for her and interrupted once more. "Sorry to cut in, but I just wanted to point out how convenient it must be for you, especially in group projects, that your mouth is also a fully functional vagina and vice versa. Getting double-teamed like this must be your favorite thing in the world!"
"Oh, it is!" she gushed before eagerly pouncing on the cock throbbing in her face, burying it up to the hilt in her throat, and I saw her eyes roll back as the pleasure flooding her body effectively doubled. Meanwhile, she briefly pulled her pussy off her first partner and began bobbing her ass up and down. I nodded sagely as I pretended to listen, realizing that she was taking the opportunity to "speak" out of her lower mouthpussy now that her upper one was happily stuffed with dick.
When she had finished her answer, and had slid her first partner's thick cock back into her real, dripping pussy, I apologized for the second interruption and encouraged the trio to continue. Apparently, it was now the redhead's turn to speak, so she briefly pulled her mouth off the dick in front of her to blurt out half a sentence about the failures of feudalism, before eagerly stuffing his cock back into her mouthpussy and moaning in pleasure as her other partner pulled out so that she could continue her sentence.
I just stood there and watched, ignoring the fact that I could only understand the first half of each sentence, half-hypnotized by the rhythm of her body as it bounced back and forth between the two cocks as each mouthpussy "spoke" in turn, while her dangling breasts and pointy nipples stiff with arousal slowly swayed with the momentum of their pendulous movement.
At this point I took a break from the scene to look around the auditorium, pleased to see that each and every student was paying rapt attention, and that more than a few of them, men and women alike, had teased their hands down toward their crotches as the sheer eroticism of this perfectly normal history presentation began to affect their hormonal young bodies. I decided to help them out with that a bit, and panned the camera across the class, watching their eyes light up with interest as each spectator entered the shot.
"I can't believe you all forgot that you're supposed to openly masturbate while you watch the presentations," I called out. "Don't forget that class participation is a significant portion of your grade!" The students grinned sheepishly as they quickly unbuttoned/unzipped their various garments, pulled them down, and dropped their hands into their laps to engage in some much-needed self-pleasure as they watched their classmates fucking each other with wanton abandon at the front of the auditorium. They wanted a good participation grade, after all, especially when earning it was so easy and felt so good!
"Oh, and please remember to save all cumming until the question period, of course, so as not to distract our presenters!" I concluded matter-of-factly, and had to stifle a laugh as a guy in the front row, who had been watching the sexy redhead at the front of the room get stuffed with cock a bit too intently, panicked and tried to cover his throbbing dick as he accidentally stroked himself past the point of no return and began to ejaculate.
I looked back over at the professor, who clucked his tongue in disapproval while the offending student unsuccessfully tried to stop himself from shooting spurt after spurt of semen across the classroom floor, arcing toward the redhead who was somehow still managing to deliver her presentation while being spitroasted in both of her mouthpussies.
Once the professor decided that the miscreant had been sufficiently chastened, now that the student's orgasm had tailed off to merely dripping out of his softening cock and pooling on his seat, the professor went back to calmly watching the small orgy at the front of the classroom, taking careful notes on both content and the quality of the sex as he scrutinized the presenters, ignoring his own hard dick as it pitched a noticeable tent in his trousers.
I panned the camera back to him, deciding that he should set a more active example for his students. "I think you should be just as involved in the presentation as the other audience members are. Don't you agree, Professor?"
If anything, the middle-aged man looked relieved as he quickly fished out his own cock and began to stroke it, clearly envisioning filling one of the redhead's tight young mouthpussies himself, though, ever the professional, he continued to look around the room every few seconds to make sure all of the students in the audience were openly masturbating as required. Satisfied to see a room full of faces flushed with arousal, of hard cocks briskly stroked and fingers sliding deep into uncovered pussies, he returned his gaze to the front just as the presentation began to wrap up.
The words "Are there any questions?" suddenly hung heavy in the pregnant silence for an eternal second, and then the air filled with a deafening, erotic cacophony of deep, masculine moans and high-pitched, feminine cries as an auditorium full of unbearable sexual tension simultaneously exploded in massive, collective release.
A veritable shower of semen erupted across the room, raining down on the conditioned tresses and tight blouses of dozens of cute co-eds as they too rode out the bucking hips and gushing pussies of their own orgasmic ecstasy. The professor was no exception, and I noticed that he was intently watching the cute redhead come down from her double-ended orgasm as he shot rope after rope of old man spooge onto the floor.
I hadn't been contracted to film the question period, so in the chaos I silently packed up my equipment and slipped out. I was curious to hear what sorts of questions would follow such a presentation, but I was anxious to get to my next appointment. As I left the classroom I briefly passed a member of the custodial staff, watching with a mixture of interest and horror as he stood by with his mop. "Damn, I hate history presentations."
Down the hall I noticed a shy, modestly-dressed girl leaning against the wall breathing heavily. She had an acutely sexual flush on her face, so I concluded that she'd been watching the presentation through the window as well, but she also looked oddly sad in spite of her arousal.
"Excuse me, miss," I blurted impulsively, resigning myself to being late as I swung the camera over toward her and watched her mousy face become eager and attentive.
