I guess that just what he was waiting to hear because, with that, he quickly got up and locked the classroom door. He walked back to me and said: "You'll do anything I want...This is interesting you little tease" he pointed to his desk "Lean over and let me see that tight little pussy of yours."
I did what I was told. I lifted my skirt up to my waist and braced my arms on his desk in doggy style fashion. He gasped.I turned my head to look at him as he ran his fingers along my ass crack and grabbed my pussy lips with his thumb and forefinger. It sent shivers through my whole body. He definitely had much more expertise than my boyfriend who would have already shoved his cock all the way up my hole. Professor Diablo slowly circled my pussy with his index and fuck finger, and dipped it inside my wet hole. I wanted him to fuck me so badly that I pushed backwards until I was humping his fingers. "You want this, you little slut," He was fully aroused as he whispered in my ear. I could only nod as I leaned my head back, coming into my first orgasm. After I came, he whispered. "Get on your hands and knees and suck me."
I obeyed and dropped to his knees eager to see the object I had fantasized about for ages. I quickly removed his trousers and took his hard cock in my hands. I was much bigger than I would even have imagined. It easily measured over ten inches. I held it with both hands as I licked the pre-cum off its ruby head. I moistened my lips as I looked made eye contact with him. I parted my lips, took his cock all the way in my mouth, and sucked hard on his long shaft. He threw his head back in ecstasy and braced himself against the desk while he held my head in place. "That's it you little slut, suck on my big cock. You like it, you dirty little tease. Get up here so I feel your hot little twat on my cock."
I returned to my position on the desk and spread my legs wide so that he could enter me doggy style. This time he didn't wait a second. He shoved the entire length of his cock in my tight hole. I let out a little scream. He grabbed my long hair and jerked me backwards with his cock still buried in my hole. "I've watched you for a long time you little slut. You think I was going to let you get away with all your little private shows that had me jacking off every night just thinking about your tight cunt. I've waited so long to show you what happens to teases. I'm going to fuck you until you're sore. From now until you graduate, you're going to be my little whore, you dirty bitch"
With that, he began to slam his big hard cock in and out of my tight hole. The pain was unbearable at first as my pussy wasn't used to a cock that big, but as he fucked me harder, I began to enjoy it. His balls slapped against my pussy as he fucked me. He reached forward, unbuttoned my blouse, and unhooked the front clasp of my bra so that he could grab my breasts in his hands. He pinched my nipples hard and I almost passed out with the pain mixed with pleasure. My pussy has never felt anything like this before. He spread my legs wider as he continued to shove his cock vigorously in and out of my tight hole over and over again. I bit on my lip to prevent my screams from escaping as he continued to fuck me hard and fast.
I began meeting his thrusts with one of my own. Doing this sent his cock all the way up to the hilt in my pussy, making my body shake violently as I came over and over again. I had never had orgasms like this before. It was amazing. "That's it you little bitch, come for me, let me feel you coming for me...oh godddd." He shuddered as he came, filling my hole with load after load of hot sticky cum. Full of exhaustion, he collapsed on top of me and I felt his cock slowly begin to soften inside me.
