A Lesson on Arousal

Talking with Amber was easy; keeping the topic outside of the classroom was a lot harder with what was going on. Thankfully, Amber made it fairly seamless and we settled into talking about a few of our mutual friends. As we talked I did as instructed and let my eyes roam over her some more.

She was gorgeous. Sexy. Enthralling. Her body was like… well, the whole situation was pornographic. I wanted to reach out and just feel her in my hands - her waist, her hips, her tits. But as we sat there I also started noticing smaller things that just made me more attracted to her. She had a little freckle or mole on the inside curve of her right breast that was super cute. When she smiled her lips curved just a bit more at the corners, like she was trying to fight it from overtaking her face. Her toes, which were slender and elegant, had an odd and cute tendency to flex as she was talking almost as much as she used her hands.

There was no hiding the fact that looking at her was making me hard, sitting in front of each other like that. At first, I was a little self-conscious about it, but she’d smile every time she looked at it, and that was encouraging as hell for me to drop my worries and just enjoy being naked with a gorgeous girl like her - not to mention all the other naked ladies around the lecture hall.

“That’s time,” Prof Sinclair called. She was as naked as the rest of us at the front of the class, her heavy breasts capped with a pair of big nipples that looked like they were almost as big as the tip of my thumb. “Now, let’s talk about Arousal. In the biological sphere, sex is the act of reproduction, and in Psychology we know that the urge to procreate in humans has caused a whole host of psychological evolutions and traits. When we’re talking about the building blocks of sex, however, we are talking about the physiological responses that come from various stimuli. Men, you are both blessed and cursed with an organ that shows off your state of arousal fairly prominently, and I can tell from here that you are all certainly aroused.”

There were chuckles across the classroom as folks glanced around, noting that each other guy was erect.

Prof Sinclair went on with her lecture, pausing occasionally to encourage the partners to re-engage in their conversations but narrowing the topics. We were also allowed to start touching ourselves, though Prof Garringer said that we should hold off on achieving orgasm if we started down that road, and made a joke about edging us.

First, we were allowed to discuss the fact that we were all naked. Then we were encouraged to pay each other compliments on what we found arousing about our partners. I had a hard time stopping with my list, which put a big smile on Amber’s face. In return, she told me she liked my eyes, and my lips and chin, and my hands. And my cock. She also did the same thing as me and listed a few non-physical qualities she liked about me - she said I was funny, liked that I seemed relaxed in the odd situation we were in, and that she felt like I was going to be a great partner for the semester and she felt lucky to have me with her.

That might have gone to my head a bit.

I could tell she was getting more turned on, too. Her nipples had started out a little firm but were now stiff little points that she would occasionally touch with her fingers. She was also sitting with her legs spread - not lewdly, but enough for her to touch herself, and just like I was releasing a little precum she was definitely getting slick. The cutest thing was that while the blush in her cheeks had faded, it was still on her upper chest, and she kept nibbling on her lower lip as she shot me little grins.

Prof Sinclair’s lecture, talking about the differences between mental, visual and physical stimulations, came to another breaking point. “Who here is feeling turned on?” she asked the class.

Every hand went up, including mine.

“Good!” she chuckled. “So am I. We’ve reached the end of our lesson on Arousal, but I do need to go through the Syllabus for the semester. Feel free to continue touching yourselves, but do please try to pay attention.”

My hand had been wrapped around my cock for a good forty minutes, stroking slowly to try and make sure I wasn’t going to pop early. I felt like my cock was ready to burst, and glancing around the room most of the other students looked the same way. The MILF was sitting with one leg bent and was grinding her pussy on her heel as she tugged on a nipple. Carisse was practically bouncing in her seat as she bounced her legs. One of the black girls, the athletic one, was biting on a pencil hard enough that it looked like she was going to snap it in pieces. And every one of the guys had an almost dazed, glassy-eyed expression whether they were stroking themselves or had stopped touching themselves in general, every cock in the place painfully rock hard.

Prof Sinclair went through the syllabus, and I listened still partially in disbelief despite all the proof I’d been getting that Garringer was telling the truth.

“Holy fuck,” I grunted under my breath. I was just sitting there squeezing my cock, trying not to stroke it because if I did I would probably blow.

“I know,” Amber chuckled beside me, stealing a glance up at my face and then down out at my cock. She was fingering herself slowly and I could see the glisten on her slimy two fingers.

“Alright, folks,” Garringer said, standing up from his seat. He hadn’t moved from his spot the entire lecture period, but the old man was still hard as he strode up beside Prof Sinclair confidently. “I think that wraps things up for the week. Feel free to help your partner out to achieve your finishes - manual stimulation only! No jumping ahead in the syllabus!”

I looked at Amber, who was biting her lower lip hard and had a needy look in her eyes as she nodded energetically. She pulled her hand from her pussy and reached over, wrapping it around my cock as we sat side by side. I groaned as she started stroking me, her small hand feeling so fucking good. I pivoted a little in my seat, our knees bumping together for a moment as I reached around and got an arm on the small of her back, pulling her a little closer as my other hand slid between her perfect, toned thighs and my fingers found her pussy. It was soft and warm and slick, and she gasped so fucking cutely as I worked a pair of fingers into her hole.

“Fuck, Nate,” she whispered, leaning forward a little more and looking like she wanted to kiss me, but holding back. I didn’t drive my fingers in and out of her and instead just buried them deep, wiggling them back and forth as I curled my thumb into the nudge against the little nub of her clit hood.

“God, I’m gonna go, Amber,” I groaned. She was stroking me fast.

“Do it,” she panted. “Come for me, Nate. Fucking come. I want to see it, it’s all I’ve been thinking about the whole fucking time.”

“Fffuuuck,” I grunted.

She was humping her hips back and forth, riding my fingers as she gasped in her breaths. The loud moans of release were echoing through the lecture hall as the other partner teams jerked and diddled each other to climax. Up at the front, Sinclair was on her knees stroking Garringer, looking like she was going to take his load on her prodigious chest.

I sucked in a breath and then let it out all at once as I went over the edge, my orgasm after an hour of being visually and aurally stimulated feeling like it was going to overwhelm my senses. I could feel my cum rocketing out of me and let out a breathless grunt deep in my chest, but I could look away from Amber’s face as she started coming as well, her eyes half closing and her cute little mouth falling a little slack as she rocked forward, her tits jiggling as she grabbed my cock with both hands and kept stroking it fast.

I finished first, sucking in a breath and letting it out hard before sucking in another one. Amber let go of my cock, leaning back away from me and thrusting her hips towards me, still caught in her own orgasm as she squeezed her eyes shut and rolled straight into a second one that seemed even more powerful but a lot shorter. I still had my fingers in her, trying to keep myself from just turning into a relaxed goo after my own release. Her pussy was clenching hard around my fingers and her juices were trailing down my wrist. She finally collapsed fully into her seat again, sucking in breaths and blinking her eyes rapidly as she gasped.

We were both splattered with my cum. It was on my chest and stomach and had hit her thighs, stomach and arms. Absent-mindedly, she lifted an arm, licked a smear of it, and smiled weakly as I groaned at the additional visual stimulation.

“Excellent work today, folks,” Garringer called from the front. He was standing behind Prof Sinclair, reaching around her to play with her pussy with one hand and her big tits with the other, and she looked like she was heading towards an orgasm of her own. “Feel free to get together with your classmates for some private studying this week, but don’t jump ahead of the syllabus. And remember, this course has a strict No Communication policy, it’s the only way we can keep the sensitive nature of our studies running. Have a great week!”

I waited until everyone else had dressed and left, and it was just Garringer and I in the lecture hall. The place smelled like sex and he headed to the back of the room and started opening some windows. We were on the third floor of the building so no one would be able to see in, but I wondered how many times he’d had to adjust the location and how many times he’d had to influence someone who had caught him.

“Believe me now, Mr Mathews?” he asked.

“Uh, yeah,” I said, nodding and then shaking my head, still finding it hard to believe it was real even if I couldn’t refute it.

“And did you have fun?” he asked, flashing me a knowing smirk.

“Yeah,” I agreed. “Uh, how is the whole ‘learn to Mesmer’ thing going to work, though?”

“Let me dig out my old notes from when Miss Allens and I worked together, and I’ll put together a lesson plan, my boy,” Prof Garringer said. “Give me a week or two. Just settle in and have fun.”
