Give me an A Grade Professor G

Mari is wet for Prof G cock, at what length would she go to get fucked hard in his classroom for an A? The semester had just started and as soon as I walked in, i noticed a very tall and handsome black man writing his email on the white board. I was hoping he was our professor. When class started he introduced himself and said he was always available during office hours for any help needed. I whispered to my friend.. man i hope he's available for some extra credit because I would love to suck that cock. I think he heard me because he asked what my question was. I asked if extra credit was available. He smiled and said of course come see me during office hours. I was too shy to go, but when I kept failing my test I felt like I had no other choice. I emailed him and he gave me an appointment. When I walked in he asked me to close the door behind me. When I did he smiled, pulled his cock out and said, now let's talk about that extra credit, I could pass you with a C if you suck my cock. I looked over to a big, black, and hard dripping pre cum veiny cock. Immediate my panties felt wet, which turned me on even more. I walked over to him and worked my tongue up and down his cock as I fingered myself as I was horny as fuck!whike he was about to cum he grabbed me by my hair and started fucking my mouth. I stopped him, pulled back and stood up. He was shocked and said why I stopped if he was really to fill my mouth. I said I didn't want a C. I wanted an A and I would do anything. He pulled me by my waist, picked up one leg on top of his desk, picked up my skirt and started fucking my pussy, which was slippery and slimy with my tasty juice. He was moaning so loud I became turned on even more. I lift myself up and bent over for his doggystyle, spread my cheeks and asked for that cock inside my ass. I asked him to damage my tight ass. He pulled out of my pussy, spit on his cock and shoved that hard cock in my tight butthole. He wrapped my hair around his hand and started fucking damaging my ass while I yelled IM FUCKING CUMMING!!!!! He fucked my ass even faster and said he was filling my ass up. He pulled out... I let the cum slide on the inner thigh and left the room after looked back smiled like a slut and said so Prof G, next time, winked at him...let the cum slide of my leg and in the next class... took my finger moved it across the cum and tasted it whole for the next hour... I was so wet again went to his office to get fucked some more but he wasnt there... cant wait until tomorrow...
