I had been enticing my college professor all semester with low cut tops. Before my final, I went to his office after hours for some tutoring and wore my smallest skirt. When I bent down in it would be so easy to stick in. I asked him some questions about the class, making sure to suck on my pencil. And then I accidentally dropped my pencil in front of him. He couldn’t control himself and instantly got hard. He took a book and tried to cover it up but I had already spotted his throbbing cock. I came over and threw the book on the ground and undid his belt. I quickly shoved his pants down before he could anything and I took his cock and immediately shoved it in the back of my throat. I deepthroated it and felt the precum slide down my wet little throat. I then took his belt and put it around my neck. I walked over to his desk and put my face down on its surface and lifted up my skirt. He came over and yanked my panties down. He took my hair and yanked it hard while he thrusted deep inside me. He instantly busted inside me . I pulled up my panties and left without saying anything. I wore the panties for the rest of the day and felt cum dripping on them. The next day I took those panties and hung them on his doorknob. I got an A in the class.
