La compañera odiosa termina enlechada

This story happened in my university times when I had to share work, exhibitions, and other things with my classmates. Without a doubt, something that bothered me quite a bit was having to team up with someone; it was very responsible for my time and most of the classmates were too careless, so I tried to always work alone. Despite this, I got along well with most of my classmates, although there was one classmate with whom I never got along throughout the entire career.

Her name is Paulina, she was the typical daddy's girl who never lacked anything; she arrived at the faculty in a latest model car, brand-name clothes, and the latest iPhone model, treated like a princess. Her whole appearance was that of a teenager, appearing to be around 15 years old, between 1.55-160 cm tall, with small breasts but a small but prominent bum, her best feature; she had white skin and red hair, as I said, the girl was a princess.

We never spoke in class until one day when the statistics professor left a long task to be done by pairs, besides she was going to form them and unfortunately for me (although later I discovered it would be the best of luck) I had been paired with the princess. She told me that since she didn't like being locked up in the faculty library filled with heat and bad smells, she would wait for me at her house at 7 am the next day; so without asking if I could or not. That's when the first conflict occurred; I told her I couldn't make it at that hour because I had a soccer training session, she responded that it wasn't her concern and that if I didn't show up at her house, I wouldn't be included in the task.

I had to cancel my training session and arrive at her house, better said at her mansion. It was in one of the most exclusive areas of the city, quite far from my home. In truth it was enormous; she made me pass through her butler and took me to the study where she was. That night she wore a swimsuit with pink straps and some lycra minishorts that made it clear she wasn't wearing anything underneath, let herself be seen as the lich would get in her vaginal lips a little bit, reluctantly asked one of the girls from the bathroom to bring sandwiches and two beers, without taking my opinion again. I was disgusted by the tone with which she spoke to the employee and scolded her:

- You shouldn't treat your employees like that, it's fine that it's your family who pays them but that doesn't give you the right to be a brat
-I'm paying for a service, they're not doing me any favors- she replied almost shouting at me.

I took my things to start working while she was answering her cell phone, I started only working, what I wanted was to finish quickly and go home. Her employee entered and unfortunately had made a mistake in the order of the lady; at which she yelled, I just kept silent, the apologetic employee left with her head down.

Something took hold of me and I said:

- You need someone to teach you good manners, slut .
- And who's going to do it, you?

Without answering, I removed my belt that I was wearing, put myself behind her and tied up her hands a little bit with Paulina, she tried to hit me but being bigger and stronger I could control her. I took off the swimsuit I was wearing and put it in her mouth.

- Now you'll know how to behave, tremendous girl- I said while holding her against the desk on all fours.

I lowered her short to her knees, gave her a hard slap on the butt as hard as I could and instantly her white skin turned red leaving my hand mark on her butt. I opened the zipper of my pants, took out my cock, wet it a bit with my head and trunk and without saying anything else started fucking her.

I noticed by the muffled sounds she was making that this first thrust was hurting her, stretching out her hands and scratching the desk with her salon nails. Slowly I felt myself getting lubricated and my Cock went in with greater ease. In a moment of rest I could see tears falling from his cheeks. I kept pumping for about ten minutes between his muffled cries and sobs. I felt my balls starting to inflame, wanting to release the accumulated semen. I couldn't take it anymore, I turned her over, put her in front of me, saw her red eyes from crying and her runny mascara, and said: - You've learned good manners today, you'll do the work alone and deliver it for both of us unless I go around telling everyone what a slut you are and how you let yourself get fucked by anyone, you dirty slut. -

I gave her a slap and made her kneel down, gave my cock a few shakes and released a large amount of semen onto her face and hair, so much that it dripped all the way to her shirt. I took out my phone from my bag and took a picture of her like that, kneeling, with her face completely smeared, her eyes red from crying and runny mascara, disheveled, a mess.

I untied her hands, removed my shirt from her mouth, got dressed, grabbed my things and left her house. I only caught a glimpse of her still kneeling there, crying. The next day she came to class without saying anything and handed me the complete work, we got a ten for the class and the teacher's commendation.

This is how you teach manners to hateful classmates.
