Female teaching assistant who was assaulted by professor

My name is Kojima Yoshiko, I'm 23 years old, and I'm a teaching assistant at the University of Tokyo's Faculty of Medicine. To my colleagues and students, I'm a stunning beauty: 168cm tall, 47kg, with measurements of 89-63-91. I have long, glossy black hair, a perfectly shaped oval face, large eyes, a small mouth, fair skin, a long neck, a high bust, a slender waist, a firm and full bottom, and long, well-proportioned legs—not the stereotypical "carrot legs" or "O-legs" of many Japanese women.

To others, I'm a striking figure at the University of Tokyo's Faculty of Medicine, always dressed in a Western-style suit and exuding a professional air. Many students and faculty secretly consider me a goddess. But what they don't know is that two years ago, when I was still a student at the University of Tokyo, I had already become the lackey of a certain important figure in the medical school!

…

This afternoon, I had a clinical medicine class. When I arrived at the classroom, the 200-seat lecture hall was already packed. Truly deserving of the title of the most popular female teacher among male students!

I wore a well-tailored, fitted skirt suit that perfectly showcased my stunning figure. The white blouse underneath had a deep V-neck, exposing large expanses of my fair skin. A closer look even revealed a glimpse of cleavage. Being a school, this was the most revealing attire I could muster. My jet-black hair was simply tied in a ponytail, and red-rimmed glasses perched on my delicate nose, giving me a playful yet alluring air. Flesh-colored stockings perfectly outlined my tempting legs, and my feet, encased in 5-centimeter silver stilettos, drew countless eyes.

"Today we'll be learning Chapter Seven..." Standing on the podium, my soft voice echoed through the classroom through the loudspeaker. I could see all the male students in the classroom staring intently at me. Even after a year as a teaching assistant, I couldn't help but feel a surge of shyness; my legs tightened, and my body felt a little hot.
Just as I finished explaining the textbook content, a slight vibration suddenly came from my lower body. I quickly squeezed my thighs together and began assigning homework. Who knew, the little thing below seemed impatient, vibrating more and more intensely. I suppressed the intense pleasure, hastily finished assigning homework, tossed out a "self-study period" message, and quickly fled the classroom, legs tucked together and toes pointing slightly inward.

I hurried to the end of the corridor. Damn it, they wouldn't even let me take the elevator! I clutched my lower abdomen and struggled up the stairs to the top floor. Under the intense stimulation of my genitals, those two flights of stairs took me a full five minutes. Waves of intense pleasure and the urge to urinate washed over me. I bit my lower lip, stubbornly moving step by step, until I just managed to grab the doorknob of the professor's office, when I could no longer hold back.

If someone happened to be on that floor at that moment, they would have seen the goddess of the University of Tokyo's medical school, Assistant Professor Kojima, kneeling in agony before Professor Ohno's office door. A long, slender right hand pressed firmly against the door, her long, fair neck arched upwards, her starry eyes half-closed, her delicate nostrils flaring with heavy breathing, her alluring cherry-like lips clenched tightly, and a seductive, suppressed moan escaping her throat. Her left hand rested on her lower abdomen, and her beautiful legs, encased in flesh-colored stockings, knelt on the floor by the doorway. The force of her movement caused her delicate heels to lift off her silver high heels. Her rounded buttocks stretched her skirt taut, and this position perfectly raised her entire rear end. A closer look would reveal that the buttocks of this beautiful, youthful teaching assistant were subtly trembling and drawing circles!

我还沉浸在高潮后的余韵中，咔嚓一声，办公室的门打开了，大野教授那张欠揍的脸凑到我耳旁，调戏道：「小美啊，告诉你多少次了，小母狗撒尿要去树下的，不能在我办公室门口啊！」

我闻言冲她翻了个白眼，刚要张口还击，突然听到楼梯那边传来上楼的声音！天啊，现在的我以多么丢脸的姿势翘着屁股跪在地上，而且以我多年被教授调教的经验，虽然刚才强忍着没有失禁，但是剧烈的高潮下，现在我灰色套裙某个位置肯定有被淫水打湿的痕迹！若是被熟识的人看到的话，我都不敢想象会如何！

我不顾高潮后的酸软，手足并用爬进教授的办公室，刚刚瘫软在松软的地毯上，就听到教授和来人打招呼。呼，还好没被看到，否则今晚学校就会传遍美女助教的流言了！

Before I could even recover, a sharp "smack" rang out as the professor slammed the door shut and slapped my pert buttocks. A burning, tingling sensation shot through me, and my whole body went limp. I tilted my flushed face and whimpered, "Professor~ you're bullying me again!"

...

Let me introduce my master, Professor Ohno Muneharu. He's 42 years old, 178cm tall, with a strong physique and a mature, weathered look. While not conventionally handsome, he exudes a reliable charm. A mischievous smile always plays on his lips. He has a bronze complexion, long limbs, and hands as delicate as a pianist's—his fingers easily reaching the sensitive spots deep within my vagina. His waist is broad and powerful, and his penis... well, it's huge! If it were fully inside, it would touch my cervix! How embarrassing!
The professor is the vice dean of the University of Tokyo's medical school, an unparalleled genius, renowned in the medical field. Single, wealthy, artistically inclined, and possessing the charm of a mature man—these combined are enough to attract the interest of 80% of women!
...

Just as I finished speaking, the professor pulled a small remote control from his pocket, pressed a few buttons, and the indicator light on the remote began flashing wildly. A strong vibration surged through my lower body again; this time, it wasn't just my clitoris, but also the depths of my vagina and anus! Under this multi-point stimulation, I couldn't help but shake my hips again. The professor put the remote control back in his pocket, laughing, "Little Mei, you've forgotten what to call me when it's just the two of us. This is your punishment!"

While enduring the intense pleasure and waves of urge to urinate, I shook my hips, knelt upright, and tried to raise my head with a smile, pleading in a sweet tone, "Master~ Mei Mei knows she was wrong~ Please forgive Mei Mei this time, Mei Mei hasn't been to the toilet for ages, and she's about to pee!"

The professor slowly walked behind his desk, sat in his large swivel chair, gently unbuckled his belt, and laughed, "Stop whining, little bitch. If you want to go to the toilet, just do your job as usual!"

Sure enough, I pursed my lips unhappily, knowing that begging was useless. I knew exactly what the "old rules" meant, of course. I knelt down, straightened my upper body, wrapped my arms behind my back, and craned my neck. This posture felt like an invisible rope was binding my arms behind my back. I gently lifted my buttocks and took a small step with my left knee. This movement naturally pulled on my lower body, making me groan and wriggle my buttocks. But even with this stimulation, I still forced myself to keep my hands behind my back, smiled at the professor, and crawled forward step by step on my knees!
It took me three minutes to crawl those few meters, and I even had a small climax in the middle. If I hadn't quickly lay down and tightened my legs, I would have definitely peed on the professor's carpet, and then there would definitely be an even more embarrassing punishment waiting for me!
Under the professor's mocking gaze, I crawled to the swivel chair with my hands behind my back and my little butt sticking out. After slightly adjusting my position, I knelt right between the professor's legs. I raised my head, my face flushed as if I were burning up, and couldn't help but roll my eyes and glare at him. Then, resignedly, I lowered my head and carefully used my cherry-like lips to hold the zipper of the professor's pants, slowly pulling it open. A large hand gently stroked my hair and lifted my chin. The professor leaned down and kissed my lips rather roughly, his hot tongue forcing its way through my teeth, sweeping forcefully from side to side in my mouth. I was instantly lost in the professor's masculine scent, a comfortable moan escaping from the corner of my mouth. Suddenly, his tongue left, and his entire mouth pressed against mine, forcibly sucking my delicate tongue out and savoring it carefully. In just a few seconds of passionate kissing, my lips were swollen and my eyes were glazed. If I hadn't quickly squeezed my legs together, I would have inevitably been brought to orgasm by the professor's kiss and mocked!

The professor released my hair, put his hands behind his head, and said with a wicked grin, "Let's begin, you little slut. Swallow my semen and I'll let you go to the toilet."

I slightly relaxed my hips to lessen the intense pleasure from the stimulation, lowered my head, and took the professor's trousers into my mouth, forcefully pulling them down. The professor cooperated by lifting his hips, allowing me to easily pull his trousers down to his knees. Despite the repeated training that had made us so in sync, the intense sensory stimulation still made both of us breathe rapidly.

I felt the professor's breath and gently kissed his penis through his underwear. Knowing him as I did, this humiliating act was more stimulating to him than simply sucking. Sure enough, I quickly felt his penis rapidly swell. I took the part of his underwear that was stretched open into my mouth, gently sucking and wetting the underwear with my saliva. Just a few seconds later, a large hand roughly reached into my shirt and began kneading my breasts. The professor was getting aroused! Seeing that
the time was right, I took the professor's underwear into my mouth and pulled it down. The professor cooperated by quickly taking off his underwear, and at the same time, he unhooked my bra. A pair of white, tender breasts sprang out, and the nipples, swollen from arousal, rubbed against my shirt, pushing me to the brink of collapse once again. I forcibly suppressed the pleasure, knowing that without the previous stimulation, the professor wouldn't have let me take off my underwear so easily; he would have teased me until I was unbearably ashamed.

Waves of pleasure washed over me, and I thought to myself that I had to finish off the professor as soon as possible. As my underwear fell down, a dark, thick penis sprang out, its veins bulging, a full 25 centimeters long and five or six centimeters in diameter. Ignoring my shame, I opened my mouth and tried my best to take it in. Heaven help me, my mouth is so small; I had to open it as wide as I could barely fit the glans! A tingling sensation shot through my nipples, and the professor's large hand pinched my nipples again. His skilled fingers made the pink nipples peek out from between his fingers. The stimulation of my nipples sent a surge of heat through my lower body. I squeezed my legs together tightly, gently lifted my buttocks, and took several deep breaths to suppress this surging tide!

To get the professor to ejaculate quickly, I rapidly moved my head up and down, letting his glans slide in and out of my mouth. My tightly pursed lips rubbed against his penis, while my neck constantly adjusted its angle, trying to penetrate deeper. To reduce the pleasure, I clenched my fists together, clamped my legs, and tightened my anus to resist the triple stimulation of my clitoris, vagina, and anus.

Two minutes later, as I continued my efforts to lessen the pleasure, the professor's glans successfully entered my throat. The moist, narrow depth of my throat stimulated him, and I could clearly feel his penis swell even more! Just as I was about to suck out another mouthful of semen, I suddenly heard the professor's laughter beside me: "I didn't expect this little bitch to have this trick up her sleeve. Getting your master's semen isn't that easy!"

I was too naive. How could the professor let me escape punishment so easily? The professor pulled out a remote control and fiddled with it quickly. A motor-like sound immediately came from my genitals, and the stimulation in the three areas intensified. Even more maddening, the part deep inside my vagina began to rotate violently, causing intense friction on my G-spot. Simultaneously, the vibrations that had previously only been at the anus began to travel deeper! And that wasn't all. The professor's large hand pulled my nipples together. Because my breasts were large and positioned centrally, I didn't feel pain; instead, a strange pleasure rippled through me!

The continuous stimulation made me want to scream. Just as I was about to spit out his penis to catch my breath, the professor's other hand pressed down on the back of my head, forcing me to swallow his entire penis. My face was pressed against the professor's lower abdomen as the entire 25-centimeter-long penis went down my throat!

Under the combined stimulation, I quickly collapsed. The pleasure I had been holding back exploded all at once. I felt intense spasms in my vagina, and a large amount of fluid gushed out. The intense vibrations of my anus made my buttocks stick up like a dog's. Suddenly, my urethra gave way, and my bladder could no longer hold back. A stream of warm urine flowed down my silk-stockinged legs! My defenses crumbled at the first sign of incontinence. I forcefully lifted my buttocks, and the urine I had been holding back for so long soaked my underwear and skirt, dripping onto the carpet.

Seeing this, the professor released his hand from my head. I spat out his penis and lay on the ground, head bowed in shame, sobbing. The number one goddess of the Tokyo University Medical School had actually knelt on the ground like a little bitch, experiencing an orgasm and losing control of my bladder!

The professor gently stroked my hair and softly comforted me, "Meimei, be good~ There's no shame in front of your master. Your master loves it when you lose control of your bladder, it's so tempting!" I whimpered in grievance. The professor reached down and touched my genitals, sniffed them, and laughed, "This experiment was a great success! Your urine doesn't smell bad at all now. All the harmful substances that needed to be eliminated have gone to your feces instead, haha." Hearing this, I felt even more embarrassed.

Indeed, to make the training more enjoyable, the professor had conducted numerous experiments on my body, all sorts of strange things, including vaginal tightening, preventing pigmentation buildup, rapid wound healing, and ensuring that restraints and bondage didn't obstruct blood flow. This experiment was to solve the unpleasant smell of my urine; it seems incontinence will become a regular occurrence from now on! These experiments are difficult to promote. I don't know what's so special about my body. Most women who participated in the experiments only managed to achieve one successful modification, but I succeeded in all of them. This is one of the reasons why the professor is so fond of me and even dismissed his previous slaves.

I breathed heavily, enjoying the pleasure of orgasm. Waves of intense pleasure washed over me for a full half minute! Seeing that my buttocks had stopped trembling, the professor slapped my buttocks, sending a ripple of flesh through my flesh. "Had enough, you little bitch? Your master hasn't had his fill yet. Climb onto the desk, be a good girl!"

Seeing me still sprawled on the floor, the professor was displeased and slapped my raised buttocks repeatedly. I screamed and quickly dragged my aching body towards the desk. The professor's interest grew even stronger, chasing after my buttocks and slapping them. The tingling pain stimulated me to ejaculate a stream of vaginal fluid and urine!

Struggling to climb onto the desk, I pressed my face against the surface under the professor's manipulations, my upper body bent forward, knees spread, and buttocks raised directly towards the professor sitting in the chair. Then, I pulled my skirt, soaked with vaginal fluid and urine, up to my waist and pleaded sweetly, "Master, Meimei can't take it anymore! Please, Master, take that thing out quickly!"

The professor slapped my buttocks a few more times, then grabbed my pantyhose and underwear and pulled them up to my knees, exposing my white, beautiful buttocks to the air. The red handprints on my snow-white flesh were incredibly alluring! My buttocks were perfectly peach-shaped, not large overall but plump and glistening. Because of the high, upturned position, even though the cleft was tight, you could still see something wriggling deep within. This wriggling thing extended, covering the perineum and then the vulva. Even more surprisingly, there wasn't a single hair from my buttocks to my vulva, except for a small, meticulously trimmed heart-shaped patch of pubic hair above my clitoris!

The professor teased my perineum with his fingers a few times. With his movements, my buttocks involuntarily twitched a few times with his fingers. "Master~" I moaned shamefully. The professor

laughed, gently prying open the part pressed against my clitoris. It turned out that the section from the clitoris to the vaginal opening was a clamp-like structure. The part he pried open was actually an electric toothbrush! Under this frenzied stimulation, my pink clitoris swelled to the size of a peanut, glistening with moisture. Even the urethral opening was clearly visible. The entire electric toy, along with the part inserted into the vagina and anus, tightly gripped the clitoris, preventing it from slipping off no matter how much I struggled—truly a weapon that drives women crazy!

The professor flicked my swollen clitoris a few times, causing me to scream and throb wildly. Then, he slowly pulled the ring at my perineum, and a thick, granular electric dildo was slowly pulled out of my vagina, accompanied by a gush of vaginal fluid that instantly soaked my inner thighs! It

had barely been pulled out an inch when it encountered resistance. The professor increased the force, and with a groan from me, an egg-sized rubber ball burst open my anal sphincter, exposed to the air. The ball was covered in lubricant and rectal secretions, vibrating violently. Surprisingly, the ball was also connected to my anus; there was clearly more than one!

As the professor pulled, a 20-centimeter-long, 4-centimeter-diameter electric dildo was pulled out of my vagina, while six rubber balls were simultaneously yanked out of my anus. The dildo was not only covered in vibrating granules, but its front section was also divided into three parts that rotated in different directions! Inserting this weapon into my vagina caused constant friction and pulling of the tender flesh, and my G-spot was intensely stimulated by the rotating granules! The rubber balls inserted into my anus were no ordinary objects either; the largest was the size of an egg, and the smallest was the size of a jujube. Even worse, all the balls were covered in tiny bristles and vibrated violently! The male medical students could never have imagined that their beloved teaching assistant, Kojima, would have such a terrifying instrument of torture forcibly inserted into her body while giving them a lecture! Once

the electric toy was completely removed from my body, the accumulated vaginal fluids flowed out uncontrollably, forming a puddle on my desk! The professor, grinning wickedly, handed me a vibrating, semen-covered electric toy. I glanced at it, then lowered my head in humiliation, my vagina involuntarily contracting and squeezing out a trickle of residual fluid!

The professor laughed heartily, flipping me onto my back, then pulling my thighs up, my exposed thighs pressed against the edge of the desk. His thick penis pressed against my clitoris, rubbing back and forth, eliciting another frenzied moan from me!

I knew what the professor wanted. The clitoral pleasure and the emptiness inside my vagina quickly overwhelmed my shame, and I pleaded in a soft voice, "Master~ give it to Meimei, give Meimei your big cock!" The professor gently thrust forward, and I closed my eyes, about to enjoy the satisfaction of my vagina being filled, when I noticed the professor watching me with a mischievous smile. It turned out his penis hadn't actually penetrated me; instead, it was rubbing against my clitoris, teasing me and causing my buttocks to thrust upwards, like a female dog with unsatisfied desire! The professor grinned wickedly, pinching and skillfully manipulating my nipples while his penis rubbed against my clitoris. My last shred of shame vanished, and I screamed wildly, "Master, give it to me! Give me your cock! Put it in! Put it in this little bitch's cunt! In this slutty cunt!"
The professor, satisfied, lifted my legs, his thick penis pressing against my vagina, thrusting forcefully. Even though my vagina was already overflowing with lustful fluids, swallowing such a massive thing was still a struggle. The moment the glans entered, I felt my vagina being stretched to its limit! The professor, experienced as he was, gently moved in and out a few times, and when I relaxed, he suddenly thrust his hips forward. I couldn't help but groan loudly as most of his penis slid into my vagina, the veins on the glans rubbing against my G-spot at the deepest part of my vagina!

The professor didn't rush to go deeper, but instead began to thrust. The frequency wasn't fast, but each time he pulled his penis back to the vaginal opening and then forcefully pushed it all the way in. Each thrust was powerful. For the first few dozen thrusts, I could remain calm, but as the professor slowly thrust in and out for nearly a hundred times, each time hitting my G-spot, I couldn't help but start moaning loudly!

Seeing this, the professor began to increase the frequency and force, going deeper and deeper with each thrust. Soon, his thick penis was completely inside, the glans already reaching the cervix! His penis thrust wildly like a pile driver, his scrotum slapping against my buttocks with a slapping sound. At this moment, I had become incoherent, "Master...so amazing...ah...so full, it's inside my uterus!...Master!"

The professor was unmoved, continuing to thrust at high speed, completely unlike his usual self. Before, he would change positions and techniques, tormenting me for half an hour until I was completely aroused. But today, it seemed he only wanted to release his pent-up desire, a storm of thrusts from the very beginning! Of course, I was begging for mercy under the professor's penis and had no time to think about such things. The frenzied intercourse quickly brought me to an orgasm. The intense orgasm made my entire back arch, my body supported only by my buttocks and shoulders, my slender waist forming an alluring curve. However, the professor showed no sign of slowing down, and I quickly reached a second orgasm, followed by a third...

In just ten minutes, I was almost constantly in a state of orgasm or about to orgasm, my vaginal fluids gushing out with each thrust of his penis, spraying everywhere! The professor also accelerated again, preparing to ejaculate. I saw his dark buttocks thrusting wildly like an engine, and a few dozen seconds later, he thrust heavily to the deepest point, a stream of hot semen pouring into the depths of my uterus!

I lay panting on the desk, my long hair cascading over my snow-white neck. My shirt was torn to shreds, my pink breasts trembling with each heavy breath. My legs, still raised, hung limply at my sides. My exposed vulva, swollen and red from the earlier abuse, was heartbreaking. A trickle of milky white semen slowly dripped from it. My flesh-colored stockings were torn in several places from the intense activity. One toe barely clung to a silver high heel, the other shoe long since fallen off the desk. My entire snow-white, full buttocks were covered in the flowing fluids of my vagina, making me look utterly pathetic! After

a short rest, the professor straightened his clothes, grabbed the electric toy lying beside him, and surprisingly inserted it into my two holes again. As the clip-on electric toothbrush gripped my clitoris, the three points vibrated gently at the slowest frequency. The professor patted my buttocks and said, "I have a social engagement tonight. Go back to the villa first, and I'll slowly indulge you tonight!" Then he closed the door and left.

Having just recovered from the afterglow of my climax, I could only force myself to tidy myself up, clenching my legs and enduring the pleasurable stimulation of my sensitive areas as I slowly made my way home! The villa the professor gave me is two kilometers from the school; I don't know how many times I'll be forced to orgasm by the vibrating toys inside my body on the way!
