Sitting in my psychology lecture hall, my gaze was fixed on my professor. Professor Robert Sullivan was one of the college's finest lecturers. He was pacing the room, his voice steady and he was talking about The Complexities of human behavioural patterns. The everyone else in this room he was just a brilliant teacher. To me, well he was the man who would be whispering my name behind his closed office door.

As his eyes drifted over the rows of students, they finally landed on me, although he remained professional I could see a spark in them that I knew I had to tease.

I had to be subtle, something unsuspecting to everyone around us. I opted for the pen against my lips. I gently dragged the pen my lower lip before sliding it into my mouth. His eyes glancing at me doing so. I saw a small curve of his lips as he caught my actions.

He cleared his throat and made sure he focused on all his students.

"I have finished marking the latest assignments and the standard was, in many cases, on point. However, I will need to speak with some of you throughout the week to discuss your submissions." He paused, his eyes landing on me again. "Tess Donovan, can you stay behind please."

My heart was pounding; my palms became sweaty. I knew exactly what was going to happen behind his office door. Once the room was empty the excitement built up inside. His eyes locked onto mine as the last of the students made their way out of the room.

"It's best we discuss this in my office, Tess."

As I walked to his office, I could already feel myself becoming wet. The thrill of being his student and breaking the rules escalated the excitement. Once the door was closed and locked, he tried to remain professional.

"You really made a mess of your paper, Tess" he looked at me. His eyes full of authority and lust. "It was rather provocative."

I looked at him, playfully and seductively I walked towards him, "I'm sorry Professor. Have I been naughty?"

I stood in front of him and pressed against him. His breathing starting to escalate. I placed my hand between his legs. His hard member already throbbing.

"Are you going to punish me?"

Robert's eyes darkened as he held my gaze. "Damn right I'm going to punish you."

My smile widened as he leaned in closer to kiss me. Both of us dripping with anticipation. His phone echoed in his office, completely killing the moment of our teacher, student role play.

He answered the phone as he kept my gaze, slipping into a more casual tone.

"Hey, honey," he said.

His wife had called at the worst time, however adrenaline and excitement got the better of me. I started to unbuckle his belt, sliding his zip down before dropping to me knees. As I pulled his boxers down, exposing his hard cock. I smiled before opening my mouth, taking him deep until he hit the back of my throat.

I heard him gasps slightly. I could hear his wife's faint voice talking as he listened. His breathing starting to hitch as his hand tangled in my hair. He was guiding me into him as deep as I could take him.

His cock was pulsing, hard and thick, and I could feel his pre-cum escaping against my tongue. His grip was demanding, his fingers gripping into my hair. I looked up to find the phone abandoned, resting on his shoulder, his eyes clamped shut as he enjoyed the pleasure I was giving him.

He realised his mistake and quickly answered his wife. "Yes, I'm still here. I'm just... trying to find something..." fumbling for words to give her. I was more turned on as the danger of what we were doing was escalating.

"Ah... fuck..." he let out, a low sound as he quickly tried to mask it with another excuse. "I'm okay... I just... ah shit... Honey I have to go I've just cut myself."

He hung up, placing the phone down. His gaze was heavy and hungry as he watched me take every inch of him into my mouth.

"You're on your way to ing this extra curriculum class, Tess." he rasped, his voice rough and thick with the struggle to stay composed. He began to thrust into my rhythm, his pace quickening and his hands gripping my hair with newfound intensity.

"Fuck... that's good!" he groaned.

I felt him surging toward his climax, his muscles coiled and his breathing ragged. It was the perfect moment. I stopped. I pulled back just enough to leave him hanging, suspended in that agonising limbo between release and restraint.

"Where would you like to punish me, Professor?" I asked, my voice dropping to a low, daring . I started to slide my underwear down from beneath my skirt, the fabric bunching around my ankle before I kicked them aside. "Your desk, or maybe here on this sofa?" I teased, walking toward his small leather sofa with a slow, deliberate sway of my hips.

I sat down, opening my legs wide before pulling my skirt up to my waist, fully exposing my slick wet pussy to his burning gaze. "Maybe I should punish myself first, Professor," I said, a playful, wicked glint in my eyes. I watched him closely as my fingers slid between my lips, the slickness of my own juice on full display, letting him see exactly how excited I had become.

He stood there, hard and erect, watching with a hunger that made the air feel electric. My fingers rubbed against my throbbing clit, the slick, wet, juice sending jolts of electricity through my body that left my breathless.

"Mm... Professor," I teased, my voice barely a whisper, "I feel so wet. I'm aching for the punishment you have to give me."

I didn't stop. I pushed myself harder, the friction of my fingers fuelling the fire inside me until I was dripping on the leather sofa beneath me, arching my back high as I was about to cum. "Ah... fuck...yes!" I screamed, my body shuddering violently under my own touch as my orgasm washed over me in waves.

I watched him walk toward me, the air crackling with the weight of what was to come. To tease him further, I placed my slick, wet, cum soaked fingers into my mouth, slowing tracing them with my tongue and gliding it between them. He finally broke, dropping to his knees between my legs, his touch light as he pressed soft kisses against my thighs.

"I want another satisfying C, and I want you to give it to me, slowly," I whispered with a triumphant smile. In this moment, I had turned the tables completely - I was making him my student in his own office.

Robert pulled my hips closer, his grips firm and demanding on my inner thighs as he parted me legs wider. He buried his face into me, his tongue sliding between my soaking lips. The wet, rhythmic sounds echoed around us. I knew how excited her was as he began to drink me up, full determination to make sure he followed on his promise to punish me.

"Oh God... yes... Professor Sullivan," I screamed, my voice echoing off the walls of the room. Just as I reached my orgasm, he stopped, forcing me to linger in that agonising, breathless suspension - teaching me exactly what it felt like to be completely at his mercy.

"You'll get your C, my way," he rasped, his voice dark with authority. He pulled me flush against him, pinning me to the leather. With his hard, throbbing cock, he slid himself between my dripping lips, deliberately massaging my clitoris with his shaft. He held me tight into him, leaving no room to move. every movement was magnified, the sensation radiating through my entire body. I matched his pace, meeting his rhythm with my hips, urgency taking over. I could feel that C fast approaching, a tidal wave of pleasure I couldn't hold back. "I'm going to cum... fuck... yes!" My body shuddered, cramping and pulsing rhythmically around his cock as I finally shattered, climaxing hard against him.

I lay my head back against the sofa, my body still pulsing and completely satisfied, when I felt his hard cock open me up, sliding deep inside me. He pulled me up, settling me onto his lap so that I was pinned between his heavy body and the leather sofa.

"How hard do you want this next C, Tess?" he growled, his voice vibrating against me.

"As hard as it takes," I replied, breathless. "Make it squirt everywhere, Professor."

He didn't hesitate. His hands clamped firmly onto my hips, pinning me down as he began to thrust. I bounced on his lap, matching his pace with a desperate rhythm. I was soaked, a hot mess, throbbing by punishment after punishment.

The friction between us grew intense, his breathing hitching as the silence of the office filled with our ragged moans and the wetness splashing off our skin. I leaned into him hungry for more.

"I want your load," I whispered against his ear.

"Fuck... yes..." he gasped, his composure completely shattered as he drove into me harder, our orgasms starting to spiral out of control.

His grip tightened, his fingers digging into my hips as he slammed his hard cock into me. "Take it all, Tess," he groaned, as his climax was close.

I leaned in, my breath hot against his neck. "I've been very naughty," I whispered.

His reaction was instant. He pushed forward, pinning me back against the sofa as his own control shattered. "Oh... fuck... Tess... yes. I'm going to explode," he groaned.

His hips shuddered violently against me, and he drove into me one final time, filling me deep as he released every bit of his hot cum into my hungry pussy. I wasn't done yet. I slid my hand between our bodies, finding my own throbbing, wet clit, he arched his back just enough to give me the space to glide my fingers against myself. I began to pleasure myself, my moans light and airy as I teased my own wet pussy.

Still buried deep inside me, he straightened his back, his eyes locked onto my hand, watching every movement I made. "You are a very naughty girl," he murmured, his voice strained. His breathing hitched, shallow and ragged, as he felt the tall-tale contraction of my body signalling that I was going to cum. "Keep going, Tess. Let me feel it," he demanded.

My body began to shudder, my moans growing deeper and more desperate. "I'm going to Cum," I whispered. Within minutes of my ission, the sensation broke over me; my muscles clamped down around his hard shaft, my hips shuddering in waves as I delivered my final, shattering orgasm against him.

When we left the office sometime later, the room was very quiet, almost eery. As I turned to face Robert, I could help but give him a satisfied smile. I gave him a final cheeky grope of his cock, the very thing that delivered that final gushing flow of cum.

My hand still pressed firmly against his cock, my fingers tangled in the fabric of his tros, and for a split second, Robert was looking down at me with a satisfied, indulgent smile. Then, the shadow fell over the desk.

Professor Grant stood in the doorway, his eyes sweeping over the scene - the dishevelled clothes, the flushed skin, and the undeniable position of my hand. He didn't speak immediately; he just cleared his throat, a sharp, authoritative sound that sliced through the room like a blade.

Robert's reaction was frantic. He shoved my hands off him with a forceful jolt, his face draining of colour as he scrambled to pull himself together.

"Professor Sullivan, a word," Grant said, his voice terrifyingly calm.

"Yes, Professor Grant. Of course," Robert stammered, his professional mask shattered and unable to find its footing.

Grant didn't even look at Robert; his gaze locked onto me, cold and clinical. "Ms Donovan. Wait in my office. Now."

My legs felt like lead as I walked past him. Every thrill Robert and I had behind that door quickly drained from my body. My heart pounding in my chest. As I glanced back, I saw Grant watching me leave the room, his eyes locked on to mine. His stare was cold, unreadable.

How was I going to get out of this situation?
