Jakob walked aimlessly, taking the long way home. He kicked at a half-flattened beer can on the sidewalk. How was he going to explain it? Two months into the new job and he's fired. Rachel was gonna be pissed!

They were counting on the extra money to finance a summer trip to Eastern Europe. Now, if they went at all, it would be mostly using her savings. She would not be pleased at this development. Jakob decided not to dwell on the negative. He would think of something.

Jakob wasn't the sharpest tool in the shed (as they say) but he was young, 25 years old, and opportunistic. He always found a way. He was blessed with good looks, tall and lean, dark hair, and an attractive open demeanor that women found attractive. When they got to know him better, they were invariably pleased to discover his other substantial attribute as well.

Now his penis, rubbing the inside of his pants leg, signaled a dull but pleasant ache, the echo of a very recent, extended episode in a state of extreme erection. His balls ached in concert, reminding him that he hadn't cum in at least 5 days. He was horny as hell, and that was probably the cause of his problem - and his newly unemployed state.

Rachel had actually helped him get the job. The local community college, which trained mostly teachers and medical assistants, scheduled figure-drawing classes for juniors in the art program. They had plenty of college-age girls picking up a few extra Euros modeling for the class, but they needed a male model. Rachel heard about the opportunity from a friend at the clinic where she worked, and she was sure Jakob would be perfect. She didn't seem to mind the fact that a lot of women would be looking at Jakob in the nude; she might have even felt a little pride in it; other women could look, but only Rachel could touch.

The interview was perfunctory. Jakob was relaxed and charming, and the art-class teacher, a woman in her forties, was pleased to get such a good candidate. He undressed for her, and she examined him as he turned around for her. She was professional about it, gave him the OK, and instructions for when and where the first class would meet.

The first two weeks went fine. The teacher posed him sitting, then reclining, and then standing, about 25 minutes per pose. The (mostly) girls in the class grinned slyly to each other when they first saw his lean body, well-defined muscles, and open, innocent face. They were going to enjoy this class!

The last pose of the third week was when the problem started. She posed him standing again, seeking something a little edgy, more arrogant. She placed his hands on his hips, chin up. He looked out across the room, beyond all the girls with easels and pads, furiously scraping and scribbling with their charcoal and pencils.

Not satisfied, the teacher came up behind him, said "...forward more", and lightly pushed his butt several centimeters, so his pelvis was thrust forward. He had to take a quick step to hold his balance. His genitals, hanging heavy in the warm September air of the classroom, swayed freely with the sudden motion, no longer resting against his tanned thighs. Several girls looked at each other, secret smiles. He suddenly felt more naked and vulnerable than he had ever felt in his life.

He knew better than to look at the toiling artists, to see where their eyes were aimed, but he was suddenly convinced that every eye in the room was gazing lustfully at his penis. He tried to think about income taxes, football, evil men with weapons coming after him. Not real enough - the immediacy of dozens of female eyes gazing at his thick, hanging flesh was overwhelming. He felt a slow but urgent heat, like a burning wave, flow into his penis, knew well from the sensation that it was filling rapidly, hanging down longer and thicker with each second, the glans-head swelling and darkening. In less than a minute it reached its full, hanging-down length, almost halfway to his knees. The girls in the art class had never seen anything like this. They stared, and he knew, from the abrupt silence, that they were all looking at just one thing.

In a mixed state of dread and supreme arousal, he waited helplessly for the next phase. His heartbeat thudded in his ears, and with each beat his penis now rose visibly, a half-centimeter higher - a few of the students with medical training realized they could accurately deduce his heart rate, simply by timing the progress of his erection. The others simply gazed at its stepwise ascent, seeing for their first time a natural phenomenon in its purest form: the spontaneous, the unclothed, the untouched erection. They were also looking at the largest erect penis they had ever seen.

In a few moments it was horizontal, and yet continued rising without a pause. Finally its rapid pace slowed, and then at about 30 degrees above horizontal, it stopped - yet it never actually stopped, but continued bobbing gently with each heartbeat, hot flesh, rigid as an oak rod.

He heard one girl's eraser scrubbing paper softly, presumably removing his penis in its former state so she could now render it more accurately, fully erect. The teacher clapped her hands, rousing the the class from its lassitude:

"Class! Finish the figure. You have five minutes!"

The girls slowly recovered from their state of shock and wonderment. They drew - hesitating at first, and then with increasing vigor and confidence. On a dozen easels a man's torso appeared, with improbably-large erection carefully rendered, from a dozen different points of view.

After the class had left, smirking and giggling, Jakob knew what was coming. And, the art teacher, being a professional, knew what had to be said.

“Jakob!”

“Umm, yes, ma’am?” He was awkwardly trying to stuff his deflating cock into his jeans, without much success.

The instructor stifled an impulse to laugh, because it was funny: Jacob’s oversized kielbasa wasn’t going to fit into those jeans until it lost a few more centimeters in length and girth.

“That’s not supposed to happen in my class, Jakob!” She tried to sound angry. It worked; his erection was softening rapidly. He pulled his jeans up to his waist and fastened the fly buttons, but the head of his cock still peeked out above the waistband.

“Un, what shouldn’t happen?” Jakob asked, and then instantly regretted it, because sounding stupid when he knew full well what she was talking about sounded even stupider. “Oh ... yeah”.

“That!” and she pointed emphatically at the head of his cock just before he pulled his shirt down over it. “I won’t have erections in my class, Jakob. We’re supposed to be professionals here, and professional male models keep their bodies under control. And that means no erections!”

Jakob didn’t tell Rachel about the incident, but lovemaking that night was spiced by Jakob’s persistent memory of becoming erect in full view of a classroom of college girls. Rachel didn’t need to know; she had fun with one very hard, very large cock.

A week later Jakob was on the low platform again, in a reclining Roman-statue sort of pose. A pillow under his butt raised his midsection higher, and he reposed on his left elbow, gazing introspectively upwards at a bunch of grapes held in his right hand. He thought the pose was a stupid cliché but he wasn’t going to say that to the instructor. He was getting paid for it, stupid or not. His penis rested languorously across his thigh. After 5 minutes his raised arm, holding up the grapes, began to ache. He thought about his tired fingers holding the grapes, and how they had brought Rachel to a squealing orgasm the night before. And how Rachel had reciprocated by sliding down and taking his cock into her mouth – well, half of it, anyway, because that’s all that would fit – and slurped and sucked and nibbled on him until...

Jakob heard a gentle sucking sound, right in front of him. Without moving his head, he swiveled his eyes down carefully, until they took in the source: a cute blond in the front row, head bent down as she appeared to be studying her drawing, holding her fat yellow pencil up to her lips, then – yes – absent-mindedly sliding it between her pursed lips, into her mouth – in and out, repeatedly, and he could see her saliva slicked on the yellow paint, hear the little pop as it pulled out, just like Rachel did as his engorged knob left her lips. Bent down slightly, her blouse was opened at the top and he could see far down, to her pert breasts and almost see a nipple there. She glanced up at him – stared right at his penis, sucked the pencil back into her mouth, pulled it out slowly – suddenly looked straight into his eyes, winked slyly at him, then her gaze slid deliberately down his torso, coming to rest on his penis again.

She narrowed her eyes, as if concentrating to memorize every detail of his extra-sized member ... which (Jakob suddenly realized) was expanding, even as she studied it. Jakob fought down dual sensations of dread and the pure deliciously erotic pleasure of a swelling erection. His penis grew longer, the swelling head sliding down his thigh until it pressed into the carpet of the riser on which he reclined. He heard her sucking again on the fat pencil, the gentle “pop” as it left her pouting lips, imagined those same lips fastened firmly around the shaft of his rapidly-hardening cock.

Now there seemed to be no stopping it, even realizing it could cost him his job. His swelling shaft began to stiffen, and its purple glans suddenly lifted off the carpet and rose steadily into the air, topping an extraordinarily large cylinder of flesh, veins displayed prominently like a map of rivers across a landscape. In less than a minute he was at full erection again, in front of a classroom of girls – some staring in awe, others smirking at each other and giggling, a few feeling genuine sympathy for him and his overwhelming embarrassment.

Class ended 5 minutes later. The class, after a few last longing glances at his still-rigid member, wandered out of the room. He put down the grapes and carefully, slowly, stood up, limbs aching from the long pose. His penis ached, too, with the unyielding pressure of an extremely firm erection. A drop of pre-cum glistened on the tip.

The instructor was furious. She strode to the classroom door, slammed it shut, walked back to face him. Impulsively she snatched up a wooden ruler on the nearest desk, and brought it down hard, twice – “SMACK! SMACK!” on the top of his rampant erection. Jakob jumped and emitted a faint grunt of pain.

“You’re through here, Jakob! You’re supposed to be a professional, I told you that the first time. A professional controls his body. A professional does not get erections, no matter what.” He wondered if she had noticed the cute blonde sucking on her pencil. The top of his penis displayed a darkening red patch where her ruler had struck, practically glowing with heat and pain.

“I’m sorry Miss Chopin. Maybe I’m not cut out for this modeling work.” In the farthest, darkest reaches of his mind, he wanted her to strike his erection again, over and over, across every inch of his eager swollen flesh, and then to press the edge, with its embedded steel strip, firmly into the shaft of his throbbing cock, because it would feel like the abusive games Rachel played sometimes, followed by sweet agonizing release. But no further blows were forthcoming; merely a final payment, a curt apology, and he was soon dressed and heading for home, erection down and thinking about Rachel.
