I walked into Mr. Arnold's office with a bit of trepidation, but I thought that I knew what I was doing and could handle myself. I had gotten an F on my latest History test, and knew that with a grade like that my parents would kill me for sure. I couldn't afford to have that happen, so I had decided to see if I could sex my way into a better grade. I was far from a virgin. I had given plenty of blowjobs, and figured that was all that Mr. Arnold would require from me, but even if not, I was experienced with vaginal sex as well, and my specialty was titty fucking. My 36D breasts were great for it, and guys seemed to like it. How a chubby, bordering on fat, girl like me had gotten so many guys to sleep with me was a mystery to many, but I guess high school guys are just desperate.
I walked up to his desk to get his attention. I had decided to come in before history class that day, as I knew that he would be in his office then and I had a free period. I had a lot of free periods this my senior year, as I didn't really give a shit anymore. I laid the test on his desk and waited for a response. I got none.
Eventually I spoke up. "Mr. Arnold, I cannot afford to have an F go on my record. Surely there is something that can be done about it. If, say, a girl was willing to earn a little extra credit," I said, in my most sultry voice. He finally looked up, and stared me straight in the eyes. I was beginning to get a little unnerved when he finally spoke up.
"What exactly did you have in mind, Missy?" he asked me. I gulped, having expected him to lead me to it and not to have to admit what I meant.
"Well, I am a woman, and you are a man, and I thought maybe you could, you know, trade some physical pleasure for a better grade for me," I said, trying to sound self assured. "I am not a virgin or anything, I know what I am doing."
His answer was swift and sure. "Close the door, strip naked, slowly, and then bend over with your hands on the chair and your legs spread," he instructed, and I grinned.
"This is going to be easier than I imagined," I thought. "So I will have to have his dick in my pussy, big deal. It is so worth it to get an A. After all, he isn't too awfully ugly." I went to the door of his office and closed it quietly, returning to the center of the floor. I took off my clothes one at a time -- my shirt, then my skirt, then my lacy red bra, followed my my lacy red panties. I stood there in just my socks and shoes, having forgotten to take them off.
He did not say anything about my feet, rather he came over behind me as I bent over the chair, kicking my legs even further apart than I had them. With no warning at all, I felt him enter my pussy. I had made sure to masturbate before coming so that I would be wet enough if need be, and he had no trouble entering me. His dick was much larger than most I had fucked, but it was pleasurable, not painful.
He did not say a word as he fucked me, taking his time, slowly moving in and out of me. Despite myself, I began to feel an orgasm building inside me. I tried to restrain myself, but couldn't, and before I knew it, I felt myself cumming all over his dick as he continued to pound me. I cried out in pleasure as the waves overtook me. He still did not say a word, but continued to pound away inside me, until at last I felt him hold my body to his as he emptied his seed inside me.
He pulled himself out of me abruptly and told me immediately to put my panties back on. I did so, wondering why he was being so abrupt, and afterwards reached for my bra. "No," he said, taking it away from me. "First clean me off."
I gulped, not really wanting to taste our mixed juices on his cock, but did so anyway, really wanting that good grade. I could feel his cum inside me beginning to leak out into my panties. I finally cleaned him to his satisfaction, then was given my clothes to put on. By that time it was time for class, so we left his office together and headed down the hallway to the classroom.
I sat in my usual chair in the back row, got out my books , and began to daydream until I heard the bell ring. I had no idea that this class would be any different than any of the others, other than my panties full of cum. As soon as the bell rang, Mr. Arnold closed the classroom door. "OK class," he said in his usual dull tone, "today we are going to do a little show and tell, to change things up a bit." I wondered what was his deal today, but didn't think much of it until he called my name.
"Missy, why don't you go first?" he said to me, and I gave him a startled and confused look.
"I, um, I didn't bring anything Mr. Arnold," I said, confused.
"Yes you did, Missy, now get up here and show us," he replied in a stern tone. I still had no idea what he was talking about, but I made my way to the front of the class. Before I knew what was happening, Mr. Arnold grabbed me by the arms, spun me around, planted my upper body on his desk face down, and yanked my skirt up and my panties down.
I wanted to die of embarrassment as I heard the class' collective gasp. I knew they could all see cum running down my legs and all over my panties. I knew they could also see my perfectly shaved pussy and my little asshole. Mr. Arnold spread my pussy lips with his fingers. "Missy has brought to show for us today her sluttiness," he said, as he held me open for all to view. I began to cry into the desk, but I had a feeling the worst was yet to come.
"I also brought something for show and tell today," he told the class as he held me pinned down on the desk. "Stay put Missy," he told me, giving me a firm swat on the ass, as he moved away from me. He walked over to the classroom computer and inserted a flash drive. He then booted up the projector and I got extremely nervous. Soon, on the room's big screen was me, asking Mr. Arnold to fuck me for a better grade. Then, of course, him fucking me, for all of my classmates to see. I began to cry even harder. When it finished, he turned off the projector and came back over to me.
During the video I had heard several of the guys in the class making sounds that led me to believe they were aroused, and I blushed deeply. Mr. Arnold stood me up and spun me back around so that I was facing my classmates, my tears streaming down my cheeks. I looked down in shame, but he forced me to hold my head up. "No no, Missy, look at your classmates, look them in the eye. Look at the lust in their eyes," he said in my ear. I forced myself to look around and did indeed see the guys, and some of the girls (although our class was, oddly, mostly guys), undressing me with their eyes.
Mr. Arnold soon did the job for them, though, grabbing a pair of scissors from his desk and cutting off each article of my clothing, except for my underwear. Those he took off and shoved into my mouth. "Wouldn't want you making too much noise, slut" he told me, and I could taste his cum on my panties.
He then told me to take off my socks and shoes. "What kind of dumb slut fucks in her socks and tennis shoes?" he asked me, which got a laugh out of the entire class and another deep blush out of me. He then did something I never would have expected. He took one of my shoes, put my sock in it, and began to piss in it. I gasped in disbelief. "If you want to wear your shoes so much," he said, "I want to at least make sure they are in a state befitting a whore like you. Any volunteers to help?" he asked the class.
