I was taking over a class for my sister one day. She told me about a lot of the kids were trouble makers. I had never really taught anything before but all my friends said I would be a natural at it if I did. While I was teaching one girl above all the others was just downright rude. Tossing paper and making the others laugh. When the bell rang I asked her to stay behind. It was the last class of the day so I knew she wouldn't be late to another class. She had already mentioned earlier that she walks to school.
As the others left I shut the door and locked it. The girl stood there looking at me, for once she had nothing to say. "Do you know why I asked you to stay behind?" she shook her head. The short skimpy skirt she had one really started to make my cock hard. I was trying to ignore it but it was very hard to do. I sat back down at the desk pulling out a pen and paper for her "You will write (I will not be Rude in Class) 100 times on this sheet then you may leave." She looked around the room. "Where do you want me to sit?" I really didn't care where she sat at that moment. "Anywhere you like. As long as you write it." She smiled at me then dropped her bag and quickly moved over to sit on my lap. It surprised me. I think I was so in shock that I didn't push her away.
I knew she could feel my hard cock from where she was sitting. She was moving around on top of it nice and slow. I could hear her starting to moan softly as she was writing. When I looked over her shoulder I saw she hadn't written but one line. "If you don't start writing I'll have to punish you." She moaned a bit louder as I said that. I made her stand up as I pulled my cock out of my pants and then pulled her back down to me sliding her panties over. Right as she sat down she felt my cock touch her pussy. She struggled to get away. I put my hand over her mouth to silence her. "If you yell, I'll make it so much worse for you." I reached around in front of her spreading her pussy lips just slightly as my cock started to slide in. It stopped only an inch or two in. I knew she was a virgin "Oh god baby you're a virgin". I knew she had to be fucked. She needed this and she would love this in every way.
I pushed into her harder as it forced passed her wall. The feeling was amazing. I looked up at her seeing tears in her eyes. "Darling don't worry you'll love this, I promise." As we stayed like that for a while I felt her hips start to move she finally wanted to feel it. You could hear our juices squishing together as my cock moved in and out of her tight pussy.
She started moving faster and I was barely able to hold myself back. She was just so tight that each motion of her made me want to cum. She started to pant and moan. I was holding her hands down to the desk and telling her to fuck me hard. The moment I knew was coming finally happened but I didn't say anything to her. I ejaculated inside her, I let my cum swirl around in her pussy while she kept fucking me. I didn't want to say anything I wanted to let her enjoy herself. She kept me hard, bouncing up and down on my cock.
A few moments later I could feel her start to tighten up on my cock. I also felt my balls tense up again, I knew we're going to cum at the same time. And we did, she pressed her pussy so hard down on my cock that I exploded deep inside her. It felt like a hose was turned on for my cock. Stream after stream of cum was released. I couldn't stop myself, she was throbbing so hard on me that it wouldn't allow me to stop cumming. When she reached down to massage my balls that didn't help. It only made me ejaculate more. But it felt so good that I didn't care. I was just happy to be fucking such a sweet tight pussy like hers.
