I went home as quickly as possible with the videotape and the photos. The tape turned out to not to be of the scene I witnessed that morning, but it surely turned me on as much. It showed Sarah undressing and fondling herself, fucking herself with two fingers. Then, saying that she was a slut, she begged to be punished. (“Please punish this slut as she deserves”, referring herself not as “me” but as “this slut”. I liked that) And her request was certainly granted. She was then made to bend over a desk and whipped until her round buttocks were all covered with red welts, and then she was fucked from behind. Although the face of the man who whipped and fucked her couldn’t be seen, I was pretty sure that it was my uncle. He barely spoke in the tape, with Sarah doing most of the talking (“Please, fuck me harder! Use me like the slut that I am!”) I jerked off while watching it. Soon I would be doing more than this with my cock, I thought to myself. I waited for Kate the following Monday after school. She smiled reluctantly when she saw me. “Hi,” she said. “Hi,” “Look, I’m sorry about last Friday. I guess I was kinda rude.” “Oh, that’s alright.” Too late for apology now. “You waiting for someone?” “I’m waiting for you, actually.” “Me?” “Yeah,” “What for?” “Come with me and I’ll show you.” “Now wait...” she stopped when I showed her the photo of Sarah quickly. “You want to come with me? Or do you me to show this to everyone around and tell them who that is?” Kate’s expression was a mixture of fear and rage when she followed me to an empty classroom which had a TV and a VCR. “What’s this all about? What have you done to my mum?” She asked, her voice a bit shaky. “Well, you can see for yourself.” I took out the videotape, put it in the VCR and started playing. Kate let out a gasp of horror when she saw her mum on the screen. She just kept staring at the screen in disbelief as her mum fingered herself, calling herself a slut, and begged to be punished. Finally, she turned to me. There were tears in her eyes. “What have you done to my mum? Why did you make her do such a terrible thing?” “I didn’t do anything. I just found this tape. And for all I know, your mum did it willingly.” “So it was your uncle?” “Yeah. But as you can see, your mum seemed to be enjoying it herself…” “You liar!” Kate shouted, and then she started crying.” “Stop shouting!” I said sternly, “unless you want someone to come in and see this tape.” That sort of reminded her. “Oh, no! Put that tape away, please. Give it to me.” “No.” “So why did you do all this? What do you want? Let me have that tape!” “No. You won’t have that tape. And besides there are many more anyway.” “Oh, god, what do you want? You have made me watch my mum doing that kind of stuff, isn’t that enough?” “No. I want you to do the same.” “What?” Kate asked in shock. “You heard me. I want you to be my slut, my slave. You will do everything I say or I’ll distribute copies of this tape in the school, and I’ll make your mum my slave.” I rehearsed those words thousands of times before, but still I could hardly believe that I actually said them! Now the die is cast. Unlike what I expected, Kate didn’t yell at me or call me names. She just sat down on a chair and covered her face with her hands. I thought about offering her some comfort (as if I could), but then thought I had to act tough. “Well, should I start make copies of the tape then?” “Alright, you bastard!” She said, and then she started to cry. “I hate you, Jim…” She said, sobbing, “I hate you, mum…” “Now that’s enough. Get up and stop crying.” My cock was already getting hard when she agreed. “C’mon, get up!” She got up and stood facing me, wiping the tears off her check. She looked adorable. She was taller than me and looked down at me with anger in her eyes. “Take off your clothes.” I said, my own voice trembling. “You…” “Shut up and do it!” I stopped her before she could come up with more inventive ways of calling me. The tape was still playing and we could hear Sarah’s moaning in this silence. Finally, biting her lip, Kate started unbuttoning her shirt. She undid all the buttons, stopped, took a quick glance at me, then with a deep breath took her shirt off, showing me her full, firm breasts covered by a white, sporty bra. Next, she kicked off her sneakers and slowly pulled off her jeans and stood there, naked except for her socks, bra and panties. She looked at me pleadingly, her face blushing. “You can keep the socks but off with the rest.” I said. “You…” she stopped, knowing better than to annoy me, and quickly unhooked her bra, and her breasts sprang free. What a sight! I could hardly control my excitement. “Now the panties” She took off her panties and stood there, completely naked except for a pair of white socks. My god, I thought as I stared at the blonde hair of her pussy, what a body. Large, firm breasts, long and athletic legs, Kate was the girl of my dreams, and now she stood naked in front of me. “So is this what you want?” I looked up and saw the defiance in her eyes. Sexually I’m sure that she’s more experience than I am (well for that matter I’m a virgin), but now I am the one who’s in charge, and she’d better remember that. “Turn around and bend over that desk.” I said. She complied with the same defiance, and didn’t even look at me as I approached and stood right behind her. She only let out a gasp when I placed my hand on her buttock. I felt the smooth white skin of her ass and started gently rubbing it. “Just get it over with you…Ouch!” She let out a cry of surprise when, instead of rubbing her I raised and brought my hand heavily down on her left butt. Her whole body jumped at the blow. Using the other hand to held down, I spanked her right butt. I kept spanking and soon the skin of her ass was red. “Ouch, ouch, no! Please! Stop! Please!” Kate started sobbing. “Oh, please, stop! I’m sorry! Please stop!” Finally I stopped when even my hand was sore. I stood there and admired my work: Kate, the best-looking girl I’ve ever met, now bent over a desk with her ass red from my spanking. Her body was shaking gently with her sobs, and she flinched as she felt my hand touched the skin of her ass again. “Don’t move,” I said as I put another hand on her back. My hand wandered all over her perfectly round ass, and soon I could feel her trembling to my touch. I slid my hand lower and felt between her legs. Her entire body stiffened as my fingers touched her lips. “You’re wet!” I said teasingly. “Do you want to be fucked?” “What?” She turned around and asked in surprise. “Beg me to fuck you.” “Wh—what? No way!” I stopped rubbing her pussy and spanked her once. “Ouch! That really hurts! Please, please don’t spank me again, please, ouch!” She cried out loudly when I spanked her again, and now I was a bit worried that someone might hear. “Please, stop!” She pleaded. “Alright, I’ll beg, I’ll beg…” “Go ahead then.” I said as I unzipped my fly and pulled out my raging hard-on. “Please…” “Please what?” “Please…f-fuck me.” “Again.” “Please…fuck me…oh!” She let out a cry as I entered her eagerly in one thrust. I held still, savoring the sensation. Then I reached out to grab her breasts. Her nipples were rock-hard, and she let out a moan as I gently pinched them. I started pumping her, and soon Kate began panting. I increased my tempo and she let out a suppressed moan. At that I couldn’t help back any longer and started shooting loads and loads of coming into her, and she kept moaning, louder and louder. I kept pumping until I felt the last drop of cum was drained from me. Together we collapsed on the desk, and I held her tight for a while. Whew, that was quick. Then I pulled out and stood up, zipping up my jeans. Kate was still gasping. “So…did you come?” I asked hesitantly. “Al-almost…” Kate answered in a dreamy voice, her eyes still closed. “No, that’s not good enough,” I said, a bit disappointed. “Turn around, now, on your back.” Kate opened her eyes and looked at me. “Wh…” “Do it!” Giving up, she complied and lay facing me on the desk. “Well, to show that I’m really not a selfish person, I would like you to come too, so I want you to play with yourself until you come.” “No really it’s okay—“ “Do it, slut!” I said, emphasizing my words with a spank on her thigh. “Or do I have to persuade you every time?” “Oh, no, no!” She pleaded, then she closed her eyes, her face blushing in shame. “oh, god, oh god,” she said. Slowly her hand reached down between her legs and started rubbing her pussy, while the other hand reached up and cupped one breast. “Spread your legs wider.” She obeyed, spreading her legs wider and rubbing her pussy with complete abandonment, faster and faster. I could see her pussy lips glisten with her juices and my come. Should have brought a camera, I thought. She was breathing now in small gasps, quicker and quicker until her entire body shuddered. Then she stopped and just lay there on the desk, with her legs spread wide, panting. “Please,” after a while, she looked up and said to me. “Can I go now?” I nodded. She quickly climbed off the desk and put on her clothes. As she pulled on her jeans, I could see that her thighs were wet with my come and her juices, but she didn’t stop to wipe them clean. “I’ll be in touch,” I said as she finished getting dressed. She looked at me briefly, then lowered her head, and rushed out of the classroom without a word.
