I sat behind my desk in the classroom, my chalk-dusted blazer buttoned at the middle to conceal my cock, which had lengthened down the side of the leg of my trousers. It had been a mistake to wear slim-cut boxers on that hot spring morning; I knew I should have masturbated before teaching this class—especially with Penny sitting in the middle desk of the front row.
I’d been assigned to be the TA of this class at the beginning of the spring semester, and it seemed like I’d had a perpetual hard-on ever since. My cock and balls constantly felt heavy and full, and I barely made it across campus. The firm, tanned flesh of the female graduate students, exposed by their tight short shorts and tank tops, had me reeling with lust. Now, in class, I gamely fought off the urge to stroke my aching erection right there underneath my desk. I had to be content with squeezing my thighs together. In doing so, I felt the sticky precome ooze down my legs as I stole glances at Penny, her raven hair parted in the middle and falling down to her shoulders, framing a long, thin face. She had an olive complexion, dark eyes and a beautiful, bright white smile with full, glossy red lips.
That day, she was wearing a thin white blouse, the first two buttons undone to reveal the tops of her ginger-colored B-cup breasts. Through the nearly sheer blouse I could see that she was braless, and I detected the cinnamon hue of her puffy areolas, clearly outlined against the snug fabric. I tried to train my eyes elsewhere, but to no avail, as the students in my writing tutorial scribbled their way through their final essays.
When Penny crossed her legs, which were perfect columns of tanned, firm flesh thanks to her training as a ballet dancer, I nearly came. Those legs were bare, except for the black pumps she wore. Her navy skirt rode high on her smooth thighs, and I imagined myself running my tongue over them, then up to the delectable pussy that waited beyond, hidden by her skirt and the white cotton panties I sometimes got a glimpse of—if I was lucky.
Dropping my hand into my lap, I furtively squeezed my cock, pulling it roughly as I looked straight at Penny. As I did, my hand hit my desk, and she looked up. I looked away, feeling my face turn crimson. When I faced her again, I found her smiling coyly at me. Then she dropped those big smoldering eyes back to her paper, but the smile didn’t fade.
At the end of class, when everyone had handed in his or her paper, I raced to my office, hiding my erection behind my briefcase. This only served to enflame my cock even more, as the leather case made contact with my balls. I couldn’t get Penny out of my mind and knew I was going to have to satisfy myself right away.
As soon as I was inside my office, I pulled down my pants and my cock popped out. Swollen and purple, it was still leaking copious amounts of precome. Swiping my hand over the tip, I used my juices to lube up my shaft, pumping it once or twice in my fist. Before I started masturbating, however, I opened the top drawer of my desk and took out a pamphlet published by the university’s dance department. There, in individual pictures, were the ballerinas in tight leotards, their delicate limbs in a variety of airy poses. I flipped to Penny’s picture. Her hair was pulled tight in a bun, her dark seductive eyes looking straight at the camera. Her leotard, unlike the others, seemed to fit tighter, molding itself to her pert breasts. Her nipples were clearly visible, straining against the fabric.
I couldn’t hold off any longer. I grabbed my cock and started masturbating furiously, panting loudly. Then suddenly my door opened, without a knock of warning. Surprised, I dropped the pamphlet and jumped up without even thinking, my cock bouncing up and down in front of me. My erection did not flag because standing there in my office, having caught me jerking off, was Penny, the object of my desire.
Her eyes moved slowly over the pamphlet on my desk, and her picture stared back up at her. “Do you think of me often when you jerk off?” she asked with a slight smirk, sounding amused, but not at all upset.
Dumbfounded, I shook my head and she approached me, not taking her eyes off my cock, which swelled to even greater proportions in her presence. She reached out and raked her wine-colored fingernails over its length. My legs weakened at the knees. “Sit,” she whispered.
I sat, my desk chair creaking beneath me. Then, without releasing my cock, Penny unbuttoned her blouse and pinched her nipples, allowing a sigh to escape her mouth. She slowly stroked my shaft as she looked into my eyes.
“Do you always jerk off while looking at my picture?”
By the way she asked I could tell that she knew I did. She smiled at me conspiratorially as she squeezed me in her fist and began pumping my cock more vigorously. At once, I felt the exquisite increase of pleasure building in my balls. Penny twisted her sun-kissed fist up and down my prick. Unable to control myself, my body stiffened and my legs went taut. I came hard, shooting come across the room as she continued to stroke my length until the last bit dribbled down her lithe fingers.
Penny raised her hand to her mouth and slowly licked it clean. Smiling that bright white smile, she said, “If you want to jerk off to me, you have my permission.” Then, without saying another word, she buttoned her blouse and left my office. I sat, sated but shaking as I thought of Penny’s last word: “Permission.” My cock started to harden again.
