I must try to make this introduction brief, as I know you are not really interested and just want to read the action. So, here I go: I am professor at a large university. My working hours are long, I am severely underpaid for the work I do, and I am often required to spend holidays preparing for classes. I love my job! No, I am not crazy. How could you not enjoy a job where you are always surrounded by cute little college coeds? Each semester I teach an introductory history course, and let me tell you, those little hotties more than make up for short pay and long hours, especially during the summer months. College girls love to show their skin and their tight bodies, and I always enjoy the effect. Have you noticed that skimpy halter tops and tube tops are back in style? Cleavage to the right of me, soft tummies to the left of me, and so my dick volleys and thunders during class time. I like to show movies and slides so I can have the room darker. That way I can ogle the girlies and think nasty thoughts while lecturing, and my hard-on won't show. But I don't just look. Oh, no! Don't forget that I am a man of some intelligence. Most coeds who take my class are looking for an easy A, and I am more than obliged to have them come into my office for "extra credit". My secretary knows that I hate to be disturbed during my lunch hour. I refuse to answer the phone or reply to messages. Ostensibly it is because I take the time to do some writing for the overpriced textbooks I sell to the students and therefore I can't be disturbed. But it also ensures that if some little hottie needs to boost her grade, our extra-credit session can be uninterrupted and undiscovered. My office is at the end of a long, nearly-empty corridor, so no one sees the girls coming and going. This past semester has been the most memorable. The first day of school I couldn't help but stare at Sherry, a beautiful tall, well-stacked, slender girl who sat the front of the room. Her halter top was very loosely tied and about ready to expose her ample, wonderfully jiggly breasts. Her hard nipples showed sweetly through the fabric. She kept eye contact with me during my introductory speech and would pointedly cross and uncross her legs, bringing my attention to the fact that she had a tiny thong on underneath her skirt and if I but looked just a little bit harder...I had to hurry up and turn on the slide projector because my dick was about to leap out of my pants. After class I retreated to my office for my lunch break. I hurriedly closed the door and was about to "stroke my own Wookie" when the door opened. Angrily, I turned to admonish my careless secretary, but I was shocked to see that it was Sherry (isn't that how all of these stories go?). She smiled admiringly at the sight of my half-exposed cock. Without another word, she kneeled down and gently ran her tongue down the length of it. Her hot breath and soft tongue against my cock was wonderful. She lapped carefully at the head, and before I knew it, she had both my dick and balls out into the open. She ran her tongue around my balls and took them one by one into her mouth and swirled her tongue around them. Her agile tongue found its way behind my balls and hit a spot I didn't even know existed. I found out later that men have a G-spot there, and that was the first time I had ever had mine touched. It was pure ecstasy; I couldn't even begin to describe it. My dick was completely turgid and longed to be crammed into some hot, moist place, it didn't matter where. I grabbed it and stroked it while she tickled the G spot. Sherry suddenly quitted the balls and with one fell move shoved my twitching cock deep into her mouth. That did it for me. I shot my load down her throat and she obligingly drank it all. Sherry stared up at me, a look of slyness in her beautiful eyes. "Did you like that, professor?" she asked. I muttered out an "Oh, it was great!" My breath was completely gone. "I need an A in this class, and I want to strike a deal with you," she arched one eyebrow coyly. "What do you have in mind?" I asked, full of visions of her lithe body bent over my desk and my dick shoved deep into her pussy. "There is plenty more where that came from. I have reached an agreement with some of the girls at my sorority house. If I don't pass this class, I have to drop out of school and move back home. My sorority needs me, though, because I am the only one over 21. They know that you pass girls who attend, ahem, extra-credit sessions. I made them agree that if one of them comes here every day on your lunch break, I will buy them drinks the rest of the semester. In return, you are to give me an A for the class. What do you say?" A tight little twat for lunch everyday? Of course I said yes! I made her promise to visit me at least once a week. She was happy to comply, adding that she hadn't seen a dick as large as mine in several months. My lunch hour being over, she left and I zipped up. It was difficult to pay attention to my work the rest of the day. The vision of Sherry bent over my cock interrupted all thought processes. The next day, I wondered if Sherry would be true to her word. Noontime arrived and I settled into my office chair. Sure enough, the door opened and in came a petite blonde girlie. She had obligingly worn a short skirt, so all I had to do was lean her over the desk and lift the skirt up. Her tight cunt was clean-shaven and so appetizing that I felt the need to eat first. I crammed my tongue deep into her tiny cunt and she moaned quietly. After five minutes of this, my dick spoke up and I was forced to obligate its demands. It was soon crammed in her pussy as deep as I could possibly get it and I rutted the girl as hard as I could. I was still horny from Sherry's sublime blow job the day before. The blonde enjoyed the thrusting and asked for more. Soon I was pounding her without regard. She asked for still more, but at that pace I couldn't hold out very long. I shot my load deep into her hole as she came. The twitchings of her post-orgasmic pussy milked the cum from my dick and I felt completely drained and satisfied. The girl thanked me and left, a trickle of cum running down her leg. Thus started the semester. True to the deal, I had a girl to fuck every school day. Sorority girls are the best - try one if you don't believe me. They just wanted fucking, it didn't matter if it was in the ass or in their mouth or whatever my whim was that day. They craved dick in all its forms. Sherry was by far my favorite. Her ass was nice and tight, and every Wednesday at noon she was bent over my desk, my cock shoved far up her ass, pounding as hard as it could. One brunette had a twin sister, and one memorable day she brought her along. I was in a breast mood that day, so I spent a lot of time suckling one while fucking the other. Then I sat back and watched them eat each other out until I grew so horny that I grabbed the girl nearest to me and shoved my dick deep into her ass. The other positioned herself so she could continue eating her sister out, and when the girl came, her screams could be heard down the hallway. I had to explain later that I had been reviewing a film on warfare and had accidentally turned it up too loud when I was fumbling with the remote. The story was believed, showing how stupid a lot of college administrators are. The end of the semester was growing nigh and I was rather upset that my supply of hot young twat would soon be gone. It was Sherry's day in my office, and I took my frustrations out on her - fucking is a great stress reliever. Her pussy was pounded like it had never been pounded before. It seemed like I couldn't get my dick deep enough into her cunt and that I couldn't suck her nipples hard enough. After we both came, she asked me if anything was the matter because I had been so rough. "Yes," I said. "I needed to talk to you about your final exam. You know it has to be three hours long." She smiled the coy smile that I had learned to love, as it always foretold some new sexual adventure. "Name the day, and I'll be ready for my final," she said, and gave me a tongue-laced kiss. I set a day and time, and she left for her next class. On the day I had named, I sat in my office and wondered what Sherry was up to. I didn't have to muse too long, as my door opened and in poured all of the sorority girls I had fucked over the semester, ten in all, along with two guys I recognized from class. I looked to Sherry. "I'm ready for my final, professor," she said, slowly taking off her skimpy tube top. The next three hours were pure bliss. My office was the site of a full-blown (pun intended) orgy. I fucked girl after girl, ate them out, pretty much did every conceivable thing I could think of. The two guys kept the other girls busy who weren't receiving my attentions. Some of the girls fondled and ate each other out while I watched and fucked another. At one point, Sherry insisted on a DP while being fucked by one of the other men. I was happy to comply, even though I hadn't tried it before. She held still and moaned softly as I slowly entered her ass inch by inch. The man beneath her, still in her pussy, groaned as my dick rubbed his. The sensation was so intense that I started to thrust away, and he did too. As I started to fuck harder, another girl came up behind me and started to lick my balls in the way I love. My dick felt like it exploded as I shot wave after wave of cum into Sherry's ass. The three hours were up much too quickly. One by one the little hotties left after I gave them one last fondle and kiss goodbye. The guys left with goofy, satisfied grins on their faces, the look all men have after having intense sex. Sherry was the last to leave. "So, professor, do I get my A for the semester?" she asked. "Of course, you more than earned it," I said as I zipped my pants and started to wipe the cum spots off the floor and desk. "Will you miss me?" I started. What a silly question! "Of course I will, Sherry. You've given me a semester that I won't forget. You are the most wonderful fucker I've ever known and have the sweetest little body I have ever seen," I answered truthfully. "Well, I won't give you the chance to miss me. I've become a history major, so we'll see each other every single semester," she said, looking up at me with her wonderful coy smile.
