There are two types of people in this world: those who enjoy math and those who do not enjoy math. Another way to divide the world is into virgins and those who have not experienced sexual intercourse. I am a professor of mathematics. I enjoy math. I have not experienced sexual intercourse.

I cannot describe what an intolerable agony it is to be a thirty-five year-old virgin. After my morning masturbation, I took a shower and proceeded to ride my bicycle to lecture. I am an assistant professor at a university that shall remain unnamed. Today I begin teaching a semester-long course on the differential geometry of curves and surfaces.

I step into class with a haughty expression of professionalism. Years of sexual frustration and intense academic competition have made me develop the facade of an asshole. I am not really so anal once you get to know me.

I am stunned to notice my class is composed entirely of the feminine gender... I hope my erection does not betray itself.

"Good morning. I am Professor Dick Cox. The course is Differential Geometry of Curves and Surfaces. The syllabus is on the website. Enough small talk. Let's commence the lecture." I said this with in the most nasal, disdainful voice I could muster.

I began scrawling some definitions on the blackboard. Since this class would be a motivation for the whole semester, I was throwing out ideas from different chapters in the book. As a result, students were starting to get bored. I did not care, except that they began to make sniggering comments.

"Hey Trish, look at the professor when he stands to the side. I see a geometric object coming out of his pants...!"

The comment was loud and the whole class giggled. That only caused my bulge to increase in volume, and I turned to the board and started to fumble with my crotch.

Meanwhile I mumbled, "It was the great Gauss who first realized that the same curve or surface can be represented by different coordinate patches... But not until Ricci and Levi-Civita was the tensor laws of transformation formalized... One may generalize the idea of curve and surface to abitrarily many dimensions without a surrounding space, and this is called a manifold... That crucial insight was Riemann's..."

My words were laced with knowledge, but to no avail. Those beautiful girls kept laughing and teasing at my painful erection. Those cruel, coy giggles... only made it harder. I lost it! I kneeled down in front of them and groaned.

"Okay, okay, I have a boner! Are you happy now?"

The women kept on giggling. They could plainly see their laughter made me excited.

A beautiful blonde stepped out of her desk. She was looking so damn hot with those brown highlights and that revealing tank top and... those tight ass-hugging jeans! That ass! It was so perfectly round and taut and tempting that... it made me drool!

"Professor Cox," she said. "Are you a virgin?"

She had her chest up to my face. I looked straight into her sumptuous cleavage at a trickle of sweat. My eyes were full of tears.

"Yes!" I confessed. "Isn't that hilarious? I'm a thirty-five year-old virgin! I've made bold and revolutionary discoveries in quantum mechanics, but I've never seen a girl's pussy except in porn! Ahh! A luscious pussy!" I hugged her and buried my face in her tits.

"Oh Professor," she purred in her most throaty and seductive tone, "Everyone goes at their own pace. Don't take yourself so seriously." She began stroking my hair and rubbing her soft pelvis against my palpitating rod.

"Aaaah," I groaned, "What's your name? I can't love you without... knowing your name!"

The woman licked my cheek several times. She removed her tank top and brassiere so I could see enjoy the full ripeness of her breasts, buried in my face. "Patricia," she whispered.

"Patricia!" I screamed and began sucking vigorously at her naked nipples. They were so warm and tender. She did not resist a bit, but massaged my arms and back with affection. "Relax... relax..." she repeated it several times.

I kept nibbling, clutching her, my private heaven. A little braver, I moved my hands down her body and held her lovely ass. I couldn't believe it. I squeezed several times and sucked her tits even harder.

"Mm-hmmmm..." murmured Patricia. I was completely immersed in the sea of her body. My desire was only to make her feel pleasure, my beautiful lady, and I began to kiss her breasts. I wanted to cover every square inch of her breasts with my lips and tongue. "Mmmm," she started to moan with real pleasure.

I kissed more. I began to kiss away from her tits a bit. "Professor, professor," she moaned. "Professor, let me teach you." I nuzzled the skin around her breasts. She pushed my hands away from her butt. Why? I buried my face deep into her tits in sadness and ecstasy. She moved her legs into a more comfortable position and slowly undid the zipper of her jeans.

I gasped for breath. "What are you going to do now?" I asked, almost frightened.

She held her finger to my lips motioning for me to be quiet. She ran her nimble finger down my face and body until it reached my crotch. Swiftly, she flicked the top of my erection causing me to groan.

Patricia removed her jeans in a delicate coquettish fashion. I could not keep myself from whimpering as she threw her socks at the chalkboard and began to play with my nipples using her toes. All that stood between me and her full naked body was a pretty black thong, complete with an ornate white Oriental design. I could see where some of her pubic hair had been shaved around the edge of her panties.

"You're really pretty..." I moaned. Her bright blue eyes widened, and she jumped at me with her strong smooth legs. I was thrown on my back, and Patricia's knickers were right in my face. They were wet, and I rubbed my cheeks against the moisture.

"You know what to do, calculus boy," she said, laughing. I shivered. Her toes began to fondle my erect prick. Panting, I cupped my hands around her ass, and slid them to the point where her underwear met her waist, one hand on each side of her body. Gripping the cloth with anticipation, my trembling hands pulled the wet thong down her body until they tightly clutched her thighs. Her shaved vagina hovered above my mouth.

"Do you like it, calculus boy? That's what pussy looks like... Do you want it, calculus boy?" She had her arms positioned over my head with one foot teasing my hard-on. Her vagina was suspended right over my lips. Propelling her body slowly towards me with the leg she was using to balance, she moved her vagina perpetually closer to my mouth. I could visually make out the slight wetness of her labia. Unable to contain myself, I stuck my tongue out a bit and raised my face to her vaginal lips. Abruptly, she raised her body out of my reach.

"You missed, math wiz," she said. Then she giggled, and started to lower herself again. I was breathing even harder and stuck my tongue out all the way. I felt a real thirst for her moist vagina. But again she raised it before I could have a taste. I became very sad. Several times she repeated this game of lowering and raising just when I was about to make contact.

"Too slow again, Pointdexter!" Her laugh was really cruel this time. I was seriously hurt now. Why was she teasing me like this? She was like every other woman I had met in my life. She lowered herself once more, even slower this time, rhythmically oscillating her body. I could not let her get away this time. With all my strength, I pre-empted her, landing a kiss on her vagina in the middle of her dance. With a quick moan, she collapsed on my face.

Her genital lips were right on my mouth. I could feel the weight of her ass. She was not too thin, not too plump, but a perfect and lovely size. Realizing this made me want to kiss her pussy again. So I stroked her smooth naked butt and pressed her vagina to my mouth and kissed it. Another slight moan betrayed her arousal. With the very end of my tongue, I circled the exterior of her labia. She bit her lip to keep from screaming and explored the interior of my thighs with her toes. She pounded the ground hard with her closed fist.

This, right above me. This vagina is what made her different from me physically, along with her large white breasts. Realizing this, I wanted to know her on the inside. I moved my tongue quickly back and forth on her pussy as she screamed in pleasure. "Spread your legs," I managed to say. She opened her pretty white legs as far as they would go, giving me permission to see the pink inside her vagina.
