The Professor Broke My Pride with Her Punishment

That afternoon the campus was half-empty because of the heat, and the last class seemed endless. Professor Inés kept solving problems on the board with that calmness of hers that drove me crazy, while I deliberately yawned in the back row and played with my phone under the desk. It wasn’t the first time I’d provoked her. I liked watching her clench her jaw, as if she had to swallow the urge to put me in my place.

I wasn’t some kid anymore. I was a grown adult, enrolled late at the university after taking a few years off from my studies. She was clearly older than me too, a woman over thirty, with that immaculate air of a serious professor concealing a body impossible to ignore. Tight blouse, straight skirt, sensible heels. And tits that showed even when she tried to appear cold.

“Nicolás, stay behind for a moment when class is over,” she said without raising her voice.

Some of my classmates looked at me with the smile of people who already knew the group idiot was about to get the usual lecture. I leaned back in my chair and answered with a half-laugh.

“Sure, prof. The usual dressing-down.”

She didn’t answer. She simply kept writing. That silence irritated me more than a reprimand.

When the bell finally rang, the classroom emptied within minutes. The entire building seemed to be melting beneath the midafternoon sun. I heard voices fading down the corridor, a door closing in the distance, and then almost nothing. Inés waited for the last female student to leave, walked to the door, and closed it gently. She didn’t lock it, but the click sounded just like a trap.

I was still sitting there, swinging one leg.

“Well?” I said. “What did I do now?”

She leaned against the desk, crossed her arms, and held my gaze. Up close, she was even better. The heat had plastered her blouse to her skin, and the edge of her bra could be made out beneath the fabric. I felt my cock growing hard, slowly but steadily, and had to adjust myself in the chair to hide it.

“You’ve been looking for a limit for weeks,” she said. “You interrupt, provoke, look where you shouldn’t, and think you’re very clever.”

I smiled insolently.

“If I’m looking, it’s because there’s something worth looking at.”

She didn’t even flinch. Her gaze dropped for a second to my crotch, where my erection was beginning to show beneath my trousers, then returned to my eyes.

“Thank you for confirming it,” she murmured.

She turned to collect some papers from the desk. She did it slowly, bending just enough for her skirt to pull tight across her ass. I was already hot and stupid. I stood without thinking too much, driven by that mixture of arrogance and lust that had gotten me into trouble so many times. I came up behind her and squeezed one of her buttocks with my whole hand.

She let out a short gasp, straightened instantly, and turned her head just enough.

“I see,” she said with a calmness that unsettled me. “You’ve decided to put yourself to the test.”

I grabbed her waist and turned her toward me. I wanted to see her lose control; I wanted to force a reaction from her. I tore open two buttons of her blouse, and the black lace of her bra appeared. Her breathing changed, but she didn’t step back.

“Don’t pretend to be offended,” I told her, my cock already hard as a rock. “I know you like the way I look at you.”

I brought my mouth to her neck. She smelled of clean perfume and the fine sweat of the end of the day. She placed one hand on my chest. For a second I thought she was going to push me away. Instead, she let me kiss her skin. That tiny concession emboldened me even more.

I opened her blouse all the way. Her tits sprang half-free of the bra, full and heavy, barely contained by the lace. I lowered my mouth and bit one of her nipples through the fabric. Inés moaned very softly. Or so I thought. Because the next second I felt a sharp jab in my side and a brutal surge tore through my body.

My jaw locked, my legs stopped supporting me, and I fell to my knees, seeing white flashes.

The last thing I saw before blacking out was her holding a small stun gun beside her thigh, her blouse open and her expression almost bored.

***

I came to with a pasty tongue and a stiff neck. It took me several seconds to understand why I couldn’t move my arms. They were tied behind the back of a chair with thick zip ties. My ankles were tied too. I was completely naked. And she, standing in front of me, was still wearing her heels and skirt, but her blouse was open and her bra was off. Her tits were bare, full, with hard, dark nipples from the heat.

“Welcome back,” she said.

I tried to sit up, but my body was still trembling from the shock. She came closer, stroked my hair with mocking tenderness, and then gave me two soft slaps on the cheek.

“You thought you were a predator,” she murmured. “And look at you now.”

My cock, which had been shrunken when I woke up, began to respond just from seeing her like that. She noticed immediately. She smiled with calm cruelty.

“That’s what I thought.”

She took a transparent plastic ruler from the desk and slowly ran it over my chest, down my abdomen, until it touched the base of my cock. The cold contact made me gasp. Then she lightly struck the tip of my cock with the ruler. Not hard—just enough to remind me who was in charge.

“You’ve been a shitty student,” she said, leaning toward my ear. “Rude, arrogant, and pretty confident for someone who gets hard while tied up.”

“Untie me,” I managed to say.

“No.”

She wrapped her hand around my cock and began to jerk me off unhurriedly. Her fingers closed firmly around the shaft, moving up and down with an exact rhythm, as if she knew perfectly where pleasure ended and desperation began. I gritted my teeth. Despite the fear, despite the humiliation, I grew completely hard in her hand.

“That works, at least,” she said. “You’re so basic.”

She pulled back my foreskin with her thumb, leaving the glans completely exposed. Then she spat on the tip. The saliva ran down hot, and she started again, this time faster, her wet fist sliding from the base to the glans while I let out moans that embarrassed even me.

“Look at me while I jerk you off,” she ordered.

I raised my eyes. She was aroused. I could see it in her short breaths, the flush in her cheeks, the way she was squeezing her thighs together. It wasn’t an act. She was getting wet while dominating me, and that drove me even crazier.

“That’s it,” she whispered. “I want you to understand that I’m not defending myself. I’m using you.”

She knelt in front of me. Her tits were level with my cock, and she slid it between them, squeezing them together with both hands. The sensation was brutal. Hot flesh, tight, soft and firm at once, swallowing my shaft as she moved it up and down between her breasts. She dribbled saliva onto the tip every few strokes, and the glans slid, shining, between her open cleavage.

My body tensed abruptly.

“I’m going to come,” I said in a broken voice.

She sped up for two seconds, just long enough to bring me to the edge, and then pulled away. The orgasm remained suspended inside me like a stab wound. I bent forward as far as my restraints allowed and let out a frustrated growl.

Inés lightly slapped my cheek with my cock.

“I never said you could come.”

I heard her open a drawer. She took out a thin cord, crouched between my legs, and lifted my scrotum with one hand. Her fingers were practiced and sure. She passed the cord beneath my balls, tightened a knot, and pulled until the pressure tore a dry moan of pain from me.

“Now we’re going to educate you.”

She went back to jerking me off, but every time my erection grew too intense, she pulled on the cord tied around my scrotum. The pain cut off my breath while keeping me erect at the same time, trapping me in a filthy mixture of pleasure and punishment. There was no escape. If I grew harder, she smiled. If I complained, she pulled harder.

“Tell the truth, Nicolás,” she whispered while squeezing my balls. “Does it turn you on when I give you orders?”

I didn’t answer.

She squeezed harder.

“Does it?”

“Yes,” I finally spat.

“I didn’t hear you.”

“Yes, fuck. Yes.”

She kissed the tip of my cock, barely brushing it with her lips, and then took it into her mouth all at once. Just the head at first, sucking slowly and obscenely, her tongue circling the glans, drawing on it until I felt my legs tremble again. Then she took more. Half of it. Almost all of it. She moved up and down without losing the rhythm, looking up at me with her eyes locked on mine while she swallowed my cock as though the decision had always been hers.

I was moaning without any dignity left. She pulled her mouth away, spat on the glans, and sank back down. Every time the base struck her lips, I gave an ineffectual jerk against the zip ties. I felt the pressure rising again in my groin, that unmistakable sign that I was about to come.

Inés let go of me again just before I did.

“No.”

“Please,” I said without thinking.

She went still for a second. Then she smiled crookedly.

“That’s better.”

She stood up, hiked her skirt to her waist, and pulled her panties aside. Her pussy was completely wet. Shining. Swollen. I had no doubt how aroused she was. She gripped my jaw hard.

“Stick out your tongue.”

I obeyed. She brought her sex to my mouth and slowly mounted my face, rubbing her wet clitoris against my tongue. Her taste filled my mouth, thick and salty. She began moving her hips in small rocking motions, controlling the pressure, forcing me to lick her exactly as she wanted.

“Firmer,” she ordered. “And don’t stop.”

I licked her as best I could with my arms immobile, moving my tongue from bottom to top, pushing it into her pussy and returning to her clitoris. She moaned, gripped the back of the chair, and kept fucking my mouth. Her thighs squeezed my temples. Whenever I found the right rhythm, she let me breathe for a second; whenever I slowed down, she pushed my face deeper between her legs.

“That’s it, asshole,” she moaned. “You’re more useful on your knees.”

She began to come over my mouth in short, wet tremors, squeezing my face between her thighs while she used me to ride out her orgasm. I kept licking until she released me, still breathing hard, her pussy shining with saliva and wetness.

“I expected nothing less,” she said.

My cock was so hard it hurt.

***

I thought that would be the end of it, that she would untie me and threaten to report me. I was wrong. She cut the ties around my wrists only to bind my hands behind my back again with the cord, tighter this time, and forced me to stand by pulling on the knot around my scrotum.

“Walk.”

“Where?”

Another pull. It hurt like hell.

“Wherever I tell you.”

She buttoned her blouse halfway, without putting her bra back on, so that her nipples showed clearly beneath the fabric, and made me follow her naked into the corridor. I walked along red-faced, with my cock half-hard and the cord tugging at my balls with every step. The building was nearly empty, but the simple risk of someone appearing made my heart race. She seemed to enjoy it.

“Keep your head down,” she said. “You don’t deserve to look ahead.”

Obedience came automatically. Every few steps she gave a small tug, and I had to hold back a whimper. She took me to the campus gym, a large, silent room that was already closed at that hour. She took a key from her pocket, opened the door, and pushed me inside.

There were ropes, mats, wall bars. More than enough equipment to imagine things that had never aroused me so intensely before.

She tied me standing to a structure of fixed bars, with my wrists raised and my legs spread. She secured the cord around my scrotum in front of me, pulling it taut and leaving my balls exposed. I felt an animal stab of shame at seeing myself like that, open and vulnerable beneath the gym’s white lights.

She stood watching me like someone assessing a tool before using it.

“Now we’ll see,” she said. “Let’s find out how much you can take.”

She opened a side cabinet and took out a small bag of toys. Nothing extreme, but enough to make me swallow: clamps, a blindfold, a short vibrator, a leather paddle. She approached in her heels calmly, as if she had all night.

First she gave me a light smack on the thighs with the paddle. Then another, harder. The leather cracked against my skin, leaving an immediate burn. She alternated blows across my thighs, ass, and lower abdomen, deliberately avoiding my cock. Each impact made me tense against the ropes, and every tension pulled on my bound balls.

“Count.”

“One.”

Another blow.

“Two.”

She kept increasing the intensity until I lost count at twelve and she forced me to start over. She enjoyed my mistakes. When she saw me sweating and breathing through my mouth, she put down the paddle, grabbed my cock, and barely stroked it with her nails. I almost came from that alone.

“You’ve become very sensitive,” she murmured.

She placed a blindfold over my eyes. The darkness multiplied everything. I felt her fingers opening my glans, the brush of her breath, a tongue I couldn’t tell whether it was going to lick or bite. The next second, a vibrator pressed against the underside of my balls, just behind my scrotum, which was stretched taut by the cord. The vibration split me in two. I moaned so loudly I was embarrassed to hear myself.

She didn’t ease up. She moved the vibrator up along the base of my cock, circled the frenulum, and went back down toward the tight sac. It was almost unbearable pleasure, so direct that it bent my body even though the ropes wouldn’t let me move. Then I felt her mouth.

She swallowed my cock as far as she could while keeping the vibrator against my balls. Her throat, the vibration, the tension of the ropes, the slight pain of my stretched scrotum—it all blended into one wave that left me trembling. She was truly fucking me with her mouth, without tenderness, letting my gasps echo through the empty gym.

“Please, let me come,” I begged between spasms.

She pulled away just far enough to speak, the tip of my cock gleaming on her lips.

“Now you know how to speak to me?”

“Yes... yes, professor.”

I heard her satisfied little laugh. Then I felt her remove the blindfold. I saw her kneeling in front of me again, her blouse completely open, her tits swaying as she jerked me off with one hand and continued playing with the vibrator against my balls with the other.

“Say it properly.”

“Please, professor, let me come.”

She stood up and kissed me. This time it was a wet, obscene kiss, tasting of my own cock and her pussy, which was still on my tongue. It disoriented me more than any blow. While she kissed me, she pulled her panties down to her ankles, kicked them aside, and turned around in front of me.

“I’m going to take it because I want to feel it,” she said. “Not because you deserve it.”

She guided my cock to her entrance and impaled herself slowly, inch by inch, letting me feel her hot pussy swallow me. I let out a hoarse, almost savage moan. She braced her hands on my thighs and began to move. At first slowly, savoring me. Then more firmly. Her ass struck my pelvis with a rhythm that left me dazed. Every downward motion buried me to the hilt. Every upward motion made me think I was going to come without permission.

“Don’t come,” she said breathlessly. “Hold it.”

It was impossible. Her pussy was tight, wet, and hot; her inner walls squeezed my cock with every thrust, and seeing her in front of me, controlling even the way she fucked me, was too much. She slipped one hand between her legs and began rubbing her clitoris while she kept riding me. The wet sound of penetration filled the room.

“Look at me,” she ordered.

I looked at her. Her mouth was open, her hair slightly disheveled, her nipples taut beneath the harsh gym lights. She was the exact image of a woman enjoying control and sex without a trace of shame. She was using me to come, and I was completely surrendered to it.

She changed the angle, pushing her ass farther back. I penetrated her more deeply. A louder moan escaped her.

“There. Fuck. There.”

She began fucking me in earnest, bouncing on my cock with a force that left me breathless. I pulled against the ropes, desperate to grab her hips, to drive my cock all the way inside her, but I couldn’t do anything except take it. That helplessness pushed me to the edge.

“Professor... I’m coming.”

She pulled off abruptly, knelt in front of me, and grabbed my cock with both hands.

“Now you are.”

She jerked me furiously, fast and precise, sucking the glans between two strokes. I didn’t last ten seconds. I came with a moan that ended almost as a shout, emptying thick jets over her tongue, mouth, chin, and part of her tits. She didn’t turn her face away. On the contrary, she gathered everything she could, swallowed, milked me through the final contraction, and then ran two fingers over her lips before slowly putting them into her mouth.

I hung from the ropes, trembling, sweaty, defeated.

Inés stood up and looked at me with insulting serenity.

“I like you better this way,” she said. “Quiet after you come.”

She loosened the cord around my scrotum, and the relief was almost as intense as the orgasm. Then she untied my wrists but left me on my knees. I didn’t stand. It didn’t even occur to me to do so.

“Listen carefully,” she said as she pulled up her panties and straightened her skirt. “What you did in the classroom would be enough to ruin you. Understood?”

I nodded.

“But you’ve also demonstrated something useful. Beneath all that swagger, there’s only a man who likes to obey when someone knows how to handle him. If you touch me without permission again, I’ll destroy you. If you obey, perhaps we’ll do this again.”

She lifted my chin with the tip of her heel.

“Do you understand?”

“Yes, professor.”

She made me pick up my clothes from the floor one piece at a time, still naked, while she watched. She didn’t allow me to dress until everything was folded on a bench. Only then did she let me cover myself, without taking her eyes off my red face and clumsy hands.

Before leaving, she came close once more, opened the collar of my shirt, and whispered in my ear:

“Tomorrow you’ll arrive early. You’ll close the door when you come in. And if I ask you what you are, you’ll tell me the truth.”

She walked away, her heels sounding firmly against the gym floor.

I stayed there, still tasting her pussy in my mouth and feeling her control driven into my body, knowing that the worst thing for my pride was that I wanted to obey her again.
