I had last night off because I needed some sleep so I wrote this instead, enjoy

I walked into lab 9 and pulled up my skirt and pulled down my top to the peak of my nipples. Mr Harvey was sitting in his chair on his laptop. He saw me and started to grin and he started to grow a bulge in his pants. Seeing his huge erection made my pussy so dripping wet and horny. Some cum dripped down my legs and he saw it. He licked his lips and said "Hello Lauren. Please sit down." I got a chair and put it as close to him as possible. When I bent down to pull up my socks he took a sneaky look down my top. I went over to him and whispered in his ear "Hmm I've been a naughty girl sir. Please punish me hard." He started to grin even more and I went over to him and sat on his lap with my wet pussy against his bulge. He started to kiss my neck and I started to moan in his ear. He slapped my ass and realised I didn't have any underwear on. He slapped my ass really hard and then he started to stick his fingers up my pussy and I started to moan louder. I rubbed my pussy
 against his bulge and he pulled my top off and started to suck on my nipples. Hmmm he was so good. I got up and pulled his cock out of his pants. I was so shocked at how big it was. He was huge and I took him into my mouth. He started to moan and hold me by my hair and told me to suck him off harder. Him ordering me made me even more horny that I got up on top of him and started to ride his big cock. "Damn girl your so fucking good." I ignored him and started to moan and bite my lips to stop me from screaming. He grabbed and squeezed and twisted my nipples. I was about to cum any minute. I felt his balls tighten and me and him cummed together. I lay my head against his chest and started to button up my school top and do up my tie. When I was done changing and got my bag Sir asked me "Would you like to come here again after school?"
"Yes sir. I can't wait" I winked at him and walked away.
