For most, sitting in a class, listening to a boring lecture about the math and science of spaceflight would be mind numbingly dull. But because of my condition, every explanation of some complicated equation or mathematical concept gave a jolt of arousal. It's weird, I know, but that was how it worked for me. My dick throbbed as she explained orbital mechanics. "Now let's take this one step further," Dr. Williams said when we reached the section on gravity waves, which caused me to stifle a groan with pleasure at her words. Suddenly, Dr. Williams turned around and looked at me. "Are you okay, ${name}?" She asked concernedly.

"Oh yeah," I replied quickly. "I'm just not feeling well."

She didn't press any further questions and went back to explaining things again, much to the delight of my cock.

As the students shuffled out of the room after class ended, Dr. Williams told me to stay behind so that we could discuss something privately after everyone left. She walked over to my desk and kneeled so we'd be face level. As our eyes met, my heart raced. Her beautiful brown eyes were full of concern and curiosity. "${name}, what happened back in class earlier today? You seemed really distracted."

"Uh..." I started nervously. "It's nothing serious, Doctor. I just have a... medical condition. That's all it is."

Her eyebrows rose up into her hairline. "Medical condition? Really?" She smiled warmly. "Can I ask exactly what your condition might be?"

My face burned redder than ever before, it always sucks having to talk about such private matters. "Well, um," I began sheepishly. "When someone explains something complex like an equation or theory to me, my brain kind of goes crazy and I get aroused."

"Excuse me?" She raised her eyebrow. "Do you mean...?"

I blushed deeper, cutting her off before she could finish that thought. "Yeah. You see, whenever I hear anyone talking about anything technical, especially if they're explaining something difficult, my body responds sexually."

She began to laugh, which was honestly a pretty common reaction from people hearing my story. "You poor thing!" She said between giggles. "But hey! At least now we know why you've been scoring A+s in every single course, right?"

"Alright, alright," I laughed nervously. "I try to be constructive about it."

She then continued with more questions. "So, can I ask what part of class you got excited by? The orbital mechanics stuff?"

"Well, pretty much everything. It's really hard to pick one specific topic," I admitted. "The entire lesson had me buzzing, I swear."

She stopped to think for a second, and then stated, "Euler's formula outlines the fundamental relationship between three-dimensional vectors and their scalars. If I understand correctly, the Euler factor describes the ratio of the square roots of the two numbers multiplied together."

My dick immediately hardened at those words, causing me to moan in front of her. "I-I knew that already..." I panted, embarrassed once more.

Dr. Williams' smile grew wider, in an almost devilish way. I then realized that she was the trifecta of danger: She's smart enough to trigger my sexual response; hot enough to make me want her badly; and prankish enough to tease me mercilessly. Damnit.

"Hmhm," she chuckled softly, and lowered her voice into a sultry whisper. "In 1733, Abraham de Moivre discovered what we now call the Euler–Poisson integral, aka the Gaussian integral after Gauss's publication in 1809."

At that point, I couldn't help myself anymore. My pants were tented uncomfortably, and I moaned loudly, trying desperately to hide the sound with one hand.
