Physical Multiplication with my math student gone wrong

A risky, suspenseful and exciting tale of a teacher claiming the true tuition fee on his student's youthful body.

Teaching had been my passion specially since I had started teaching this girl named Susan near my town.

I had been teaching Susan for almost six months. She was a tiny, delicate 15-year-old with pale, milky-white skin and beautiful ginger-red hair that fell down her back like fire. Her body was small and undeveloped, which only made her look even more innocent and fragile.

Every Tuesday and Thursday evening, I went to her house for private math tuition. Her parents were usually home, but today they had gone out for a family function and said they would return by 9 PM. It was already 7:30 PM.

Susan was wearing a simple white t-shirt and pink shorts that barely reached mid-thigh. She sat beside me on the study table, solving problems quietly.

"Sir Carl, I don't understand this equation..." she said softly, biting her lower lip.

I moved my chair closer to her. Her sweet, childish scent filled my nose. My eyes kept drifting to her thin white neck and the way her small breasts pushed against her t-shirt.

"Let me show you," I said, placing my hand on her thigh under the table.

Susan froze. She looked at my hand, then at me with nervous eyes.

"Sir... your hand..." she whispered.

I squeezed her soft, pale thigh gently. "Focus on the question, Susan."

She tried to move my hand away, but I held it there firmly.

"Sir Carl, please... this is not right," she said, her voice shaking slightly. "My parents can come back anytime."

I smiled and leaned closer to her ear.

"That's what makes it exciting, doesn't it?" I whispered. "Now be a good girl and sit still."

I slowly moved my hand higher up her thigh, sliding under the edge of her pink shorts. Her skin was incredibly soft and smooth. Susan trembled and tried to close her legs.

"Sir, stop... please... I don't want this," she begged quietly, her big green eyes filling with fear.

But her resistance only made my cock harder.

I turned her chair toward me and pulled her closer. She was so small and light that it was easy.

"Susan," I said calmly but firmly, "you've been teasing me for months with these tiny shorts and that innocent face. Today, Sir is going to teach you something more important than math."

She shook her head quickly.

"No... Sir Carl, please... I'm only 15. This is wrong," she pleaded, her voice cracking.

I grabbed her chin gently but forcefully and made her look at me.

"Keep your voice down, little girl. Unless you want your parents to come home and see their precious daughter with her tutor's hand between her legs."

Susan went quiet, breathing fast. Tears welled up in her eyes, but she didn't stop fighting me.

I grabbed Susan’s chin more firmly, forcing her to look straight into my eyes.

"Keep your voice down," I warned her coldly. "Your parents will be back soon. You don’t want them to see what a naughty little girl their daughter is, do you?"

Susan’s eyes widened in panic. She suddenly pushed my chest with both her small hands, trying to get away.

"Sir Carl, no! Please stop!" she cried out, her voice trembling. "I don’t want this! Let me go!"

She tried to stand up from the chair, but I was much stronger. I wrapped one arm around her tiny waist and pulled her roughly onto my lap, facing me. Her legs straddled my thighs as she struggled.

"Sir, please! I’m begging you!" she whimpered, pushing desperately against my chest. "I’ll tell my parents! I swear I’ll tell them!"

"Shut up," I growled, grabbing both her wrists and pinning them behind her back with one hand. My other hand moved up and squeezed her small breast hard over her t-shirt.

Susan gasped sharply and twisted her body violently.

"Stop it! It hurts! Sir Carl, please don’t do this!" she sobbed, tears now running down her pale cheeks. Her red hair fell messily across her face as she struggled.

I ignored her cries and pulled her t-shirt up roughly, exposing her small, pale breasts. Her pink nipples were stiff from fear. I immediately latched my mouth onto one, sucking hard while my tongue flicked across it.

"Ahh! Nooo!" Susan cried, trying to pull her wrists free. "Please stop! I don’t like it! Sir, I’m begging you!"

Her desperate resistance only made me more aggressive. I bit down lightly on her nipple, making her yelp in pain. My free hand slid down and forced its way inside her pink shorts, cupping her smooth, bare pussy.

Susan’s whole body jerked violently.

"No! Not there! Please Sir, take your hand out!" she pleaded, crying harder. "I’m only 15… this is wrong! My parents will come back any minute!"

I rubbed her tiny slit roughly with two fingers while looking straight into her tear-filled eyes.

"You can cry and beg all you want, Susan," I said darkly, "but your little pussy is already getting wet. Your body knows what it wants, even if you don’t."

She shook her head frantically.

"That’s not true! Please stop touching me there! I hate it!" she sobbed, still trying to twist away from my fingers.

I pushed one finger inside her tight virgin hole. Susan let out a sharp, pained cry.

"Ahhh! It hurts! Take it out! Please take it out, Sir!"

I held her tightly, fingering her slowly while sucking on her small breasts. Her pale skin was turning pink from my rough handling. She kept crying and begging, her small body trembling in my lap.

The clock on the wall showed 8:05 PM.

Her parents would be back in about 10 minutes.

I pulled my finger out of her tight hole and lifted Susan up effortlessly. She was so small and light. I carried her to the nearby sofa and threw her down on her back. Before she could scramble away, I climbed on top of her, pinning her down with my full weight.

"Sir Carl, please! No more! I don’t want this!" she cried desperately, pushing at my shoulders and chest with all her little strength. "Get off me! Please get off!"

I forced her legs wide apart and positioned myself between them. My thick, hard cock pressed against her tiny entrance. Susan’s eyes widened in terror as she felt the size.

"No! No! Sir, it’s too big! Please don’t put it inside me!" she screamed, squirming wildly underneath me. Her small body twisted and bucked, her pale legs kicking frantically. "I’ll tell my parents everything! Stop! Please!"

I grabbed her wrists again and pinned them above her head with one hand. With my other hand, I held her jaw and forced a deep, aggressive kiss onto her mouth. I shoved my tongue inside, licking every corner of her warm, sweet mouth, sucking on her tongue while she whimpered and tried to turn her head away.

I broke the kiss only to bury my face into her neck, sniffing deeply at her soft, pale skin. She smelled like strawberry shampoo and fear. I licked her neck hungrily, dragging my tongue across her throat and collarbone.

Susan continued squirming violently beneath me.

"Stop licking me! Please Sir… I feel disgusting… let me go!" she sobbed.

I ignored her and pushed the thick head of my cock against her tiny opening. Then, in one powerful thrust, I forced myself inside her.

Susan’s whole body arched violently as she let out a sharp, pained cry.

"AAHHHH! It hurts! Take it out! Please take it out!" she screamed, her small body thrashing wildly under me.

I groaned in pleasure as her extremely tight virgin pussy gripped my cock like a vice. I pressed my entire body down on her, making sure there was no gap between us. My hairy chest crushed her small breasts. My stomach pressed fully against her flat belly. My thighs wrapped around hers. I wanted every inch of my skin touching hers.

I started fucking her with hard, rutty thrusts. Short, aggressive, and animalistic. My hips slammed against her small body rapidly, keeping my cock buried deep inside her most of the time. The sofa creaked loudly with every violent movement.

Susan squirmed like a wild animal beneath me. Her back arched, her hips twisted left and right, her legs kicked desperately, trying to push me off.

"Stop! It’s tearing me! Sir Carl, please stop!" she cried hysterically, tears flowing down her red cheeks. "You’re too big… it hurts so much!"

I buried my face back into her neck, sniffing and licking her sweaty skin like a beast while pounding into her. I moved to her armpits, sniffing her scent deeply and licking the soft, pale skin there. All the while, my cock kept rutting into her tight pussy in fast, short, brutal bursts.

I kissed her again, even more aggressively this time. I sucked on her tongue, licked the inside of her mouth, and bit her lower lip while my body remained completely glued to hers, chest to chest, belly to belly, thighs to thighs, with no space left between us.

"You feel so good, Susan," I groaned into her mouth. "Your tight little pussy is squeezing my cock so perfectly."

She kept squirming and crying underneath me, her small body jerking with every hard thrust.

"Please… pull it out… my parents will come… I can’t take it anymore…" she begged between sobs, her voice breaking.

But I only fucked her harder, my hips moving in fast, needy rutting motions, slamming my cock deep into her womb again and again. Her pale, delicate body was completely trapped under my much larger frame as I claimed her.

The clock now showed 8:14 PM.

Her parents could return at any moment. Her parents could walk through the door at any second.

I was fucking Susan harder now, my hips moving in fast, short, animalistic bursts. My thick cock slammed repeatedly into her tiny, stretched pussy. Her small body was completely trapped under mine, every inch of our skin pressed together with no gaps.

Susan was crying and squirming desperately beneath me.

"Sir Carl! Please stop! My parents will be here any moment!" she sobbed loudly, her voice filled with panic. "Please pull it out! I’m begging you!"

She twisted her hips wildly, trying to throw me off, her pale legs kicking frantically. But I held her down tighter, my chest crushing her small breasts, my belly pressed flat against hers, my thighs locked around her.

I buried my face into her neck, sniffing her scent deeply, then licked her sweaty skin like a hungry animal. I moved to her armpit, inhaling her raw teenage smell before dragging my tongue across it.

"Stop smelling me! Stop licking me! This is disgusting!" she cried, her voice cracking as she tried to push my head away.

I kissed her aggressively again, forcing my tongue deep into her mouth, sucking on her tongue while groaning. My hips never stopped their rutting motion, fast, short, powerful thrusts that kept my cock buried deep inside her.

"Sir! Please! They’re going to catch us!" she screamed, tears streaming down her face. "Take it out! Don’t cum inside me! Please Sir Carl, I’m begging you!"

Her desperate pleas and the fear in her voice pushed me over the edge.

I pressed my full weight down on her tiny body, wrapping myself completely around her. My chest rubbed hard against her breasts, my stomach moved against her flat belly, and my cock throbbed violently inside her tight walls.

"I’m going to cum, Susan," I growled into her ear.

"NOOO! Please don’t! Not inside me!" she screamed in terror, squirming and thrashing violently under me. "Pull it out! Sir, please! My parents are coming!"

At that exact moment, we both heard the sound of a car pulling into the driveway.

I held her wrists above her head and slammed my hips forward one last time, burying my cock as deep as possible into her young pussy.

My entire body tensed.

We heard the sounds of door closing on the car and opening on the house. "Fuck...", I groaned in Susan's ears. As my whole body shook my head shaking and my nose moving violently on her skin.

"NO! SIR CARL! STOP! YOU’RE CUMMING INSIDE ME!" she screamed at the top of her lungs, her small body shaking uncontrollably underneath me. "PAPA HELP!!!!", she shouted out in disgust and cry.

Thick, heavy ropes of cum exploded from my cock, shooting powerfully straight into her womb. I groaned loudly as I kept pumping load after load of hot semen deep inside her. My cock pulsed again and again, flooding her completely.

"SUSAN WHAT HAPPENED", I heard her father shouting and thumping up the stairs.

Susan’s eyes widened in horror as she felt me hold her arms up forcefully, and rubbing my body against hers and still licking her armpit, as the knob to the room door opened up and I heard nothing but a gasp from them and from me. Difference one was a gasp of emptying out semen and the other of horror.
