I hopped out of my car and locked the door out of habit, though I was only going to be here for a few minutes. I had left my video camera at my girlfriend's house the night before, and I was running inside to grab it. I had gotten it for Christmas two years back and I rarely go anywhere without it. My girlfriend, Michelle, isn't exactly a looker, but she's gorgeous in my eyes: long, auburn hair, blue-grey eyes the color of storm clouds, perky breasts, and a well-rounded figure, not skinny but definitely not fat. I'd met her three years prior, and we still hadn't lost the spark. But on this day, Michelle was at work, and I was merely stopping by for my camera. Or, so I thought. I located the spare key under the mat (such an original hiding place), and unlocked the front door. I stepped inside, trying to recall where exactly I had left my camera. If I remembered correctly, I'd been messing around with it in the basement, so it was probably down there. I passed through the living room and opened the door to the basement stairs. I was halfway down the spiraling steps when I paused, for I could hear noises coming from below. Very intriguing noises. It was the obvious sound of a female moaning in sexual pleasure, and I contemplated for a moment heading back upstairs. Michelle currently lived with her younger sister, Melissa, and since I knew Michelle was at work, it was a simple deduction that the sounds emanating from below came from her sister. At 20 years old, Melissa is pretty, and looks a lot like her sister, but her hair is a little darker and straighter, her skin paler, and she has larger breasts, probably a large C-cup. She's also always been a whiny, spoiled bitch, and quite a few times I've had to stop myself from making some scathing comment in her direction. As I turned to head up the stairs, a thought struck me. As far as I knew, Melissa didn't have a boyfriend, and she was far too stuck-up to fuck on the first date. That meant that the noises I was hearing were probably due to Melissa masturbating... and that was an opportunity that was hard to pass up. Quietly, cautiously, I crept down the last few stairs and poked my head around the corner. I had expected to catch an eyeful, but I wasn't ready for what I saw. There was Melissa, naked on all fours on the rug in the center of the room, but she wasn't masturbating. Instead, her dog Toby was hunched over her, humping away, as Melissa shrieked in pleasure. My mouth dropped open. Melissa was getting fucked by her dog, and she was absolutely loving it. I had a great view from the side as her boobs swayed back and forth in rhythm with Toby's frantic thrusting. Toby is a Lab mix, black and grey with a white underbelly. He's a good-sized dog, not like a Great Dane or anything, but large enough to make the scene before me very possible. I couldn't do much other than stare. This had to be one of the hottest things I had ever seen, and the most surprising part of it was that it was spoiled, stuck-up Melissa, of all people, who was getting reamed by the dog. I unconsciously stepped off the stairs, onto the cement floor, and Melissa instantly raised her head. Her complexion paled when she saw me staring at her. "P... P... Pete?!" She managed. I didn't say anything; I was still entranced by the scene in front of me. A panicked Melissa desperately tried to push the dog off of her, but Toby wouldn't budge. He'd stopped thrusting and now just sat there on top of her with a dumb look on his face. I took a few steps closer. "It looks like he's knotted with you," I said, "Which means you aren't going anywhere any time soon." I was amazed at how nonchalant I was being. "Shit, just... just look away, please!" Melissa had tears pooling in her eyes; I could tell she was embarrassed beyond words, which made the whole thing even more enjoyable. "Actually," I said, relishing my position of power, "I think I'm going to stare a little more. It's not every day you get to see a slut being fucked by her dog." I squatted down and made an obvious show of checking out her body. "Seriously, Pete," she pleaded, "Just go away... PLEASE!" "Yeah, not gonna happen," I replied. All of a sudden, my gaze fell on the couch, and there was my camera case, right where I'd left it the night before. This was too good to be true. I stood and walked past Melissa to the couch, opened the case, and took out my video camera. "What are you doing?" Melissa asked, for she couldn't see what I had in my hands. "Oh, just... capturing memories," I responded sardonically, turning towards her as I turned the camera on. "Oh... oh no, oh please no..." Melissa looked totally mortified. "Oh yes," I said. "Smile for the camera, slut!" As I began recording, Melissa turned her head away, and tried rotating to put her back to me, but her current situation made that more than a little difficult. "No, no," I reprimanded her, "I want to see your face." She didn't budge, so I walked around to her other side. She turned her head again. This time I took a step towards her and slapped her across the cheek. She gasped and looked up at me, tears in her eyes. "That's better," I said. "Now just one more thing, and if you want this to be over quickly, you'll do exactly as I say, got that?" Melissa just glared at me. "You're going to look into the camera, and say the following words: `I, Melissa Anderson, am a dirty little slut who loves to get fucked by dogs.'" Melissa looked down at the floor, trembling. For a minute, I thought I was going to have to be more forceful, but then: "I, Melissa, Anderson..." She said it through gritted teeth and with obvious malice. "No," I scolded her, "Say it like you mean it. Say it like it's the truth - because it IS the truth. You ARE a dirty slut who loves fucking dogs, aren't you?" Melissa tried once more in vain to get herself out from under Toby, but they were knotted tight, and a grimace flickered across her face from her attempt to escape. "Say it, bitch," I commanded. "I, Melissa Anderson..." She heaved a sigh. "...Am a dirty little slut who loves to get fucked by dogs." "There we go," I said cheerfully, snapping the camera shut. The entire time, I had been so focused on getting some blackmail on Melissa that I somehow failed to notice my raging erection, but now it was calling out for attention. I dropped the camera with the incriminating evidence back onto the couch, and then turned back to Melissa. "Okay, slut," I said, unzipping my jeans, pulling out my dick, and shoving it in her face, "Suck it." "Hell no!" she practically shouted, recoiling. "Alright," I replied, "In that case, I'll just start showing that video around... I think I'll start with your parents, see what they think of it." "No, oh god no, please..." Her voice trailed off as she began to realize the situation she was in. "Then suck it. Give me a blowjob and no one ever sees that tape." She looked up at me, venom in her eyes, but then reached out her left hand and grabbed my dick. "That's right," I said encouragingly, "Now use your mouth. I know you know how to give a blowjob; you're such a dirty little slut you'd let a dog fuck you, for god's sake." Toby cocked his head to the side as I referenced him, and shifted a little bit, eliciting an involuntary squeal from the bitch he was knotted with. Melissa began sobbing, her back heaving up and down, but slowly, reluctantly, she opened her mouth and wrapped her lips around my throbbing member. "Ohh, that's a good girl,' I said as Melissa began pumping her head up and down on my dick. It felt so good, especially knowing that the whole time she had a pussy full of dog cock. She was a good little cocksucker, too - she was expertly using her tongue as her lips ran across my shaft, and she seemed to actually be getting into it. "That's right, you little whore," I said, making sure to berate her with every sentence, "You like sucking my dick, don't you?" I reached down and fondled Melissa's tits as they swayed beneath her. They were soft and supple, except for her nipples, which were hard as rocks. "Hey!" she cried, momentarily letting my cock free, "Don't squeeze so hard." "I'll squeeze as hard as I want to, bitch," I said and, just to prove my point, I took her left breast in my hand and squeezed as hard as I could, making her gasp in pain. I may have been going a little overboard, but I was taking out three years' worth of aggression towards the little bitch, and I was going to savor every moment of it. "Now keep blowing me," I growled, and she complied, going down on my cock with a renewed furor. Maybe she figured if she could get me off quickly, it'd be over sooner. After another minute or so of Melissa expertly sucking my dick, Toby finally freed himself from her, his penis flopping out of Melissa's pussy, followed by a gush of semen. Melissa moaned unconsciously as her dog's cum poured out of her, and I pulled her off my cock. I had realized before she did that Toby finishing with her had afforded her the freedom to pull away from me, and I wasn't about to let that happen. "As much as I hate sloppy seconds," I said to her, "I think your pussy is just begging for a human cock, don't you?" Toby had retreated to a corner of the basement, where he curled up, watching us. "Wha... no!" she shouted, and struggled to pull free, but I kept a firm grip on her shoulders. "How quickly we forget, hmm? Here's the deal: you let me fuck you, or that video of a dog and his bitch goes on the internet." She began sobbing anew, shaking her head, before finally looking up at me. "I'll tell Michelle." "And I'll deny everything," I responded. "Who is she going to believe, her bitch of a sister or her loving boyfriend?" Melissa was silent. "And, if you do that, I think I'll start by sending the video out to every e-mail account on the UMASS server." I figured the reference to her school would spur a reaction, and I wasn't wrong. "FINE!" she practically screamed, "Do whatever the fuck you want to me, just don't, please... don't..." "I won't, so long as I get to fuck that cunt of yours. Now up." I pulled her to her feet and shoved her towards the pool table on the other side of the room. She stumbled into it hard, her pussy still leaking Toby's cum all over the floor. I followed close behind her and forcibly pushed her face into the felt so that she was bent over the table, her juicy pussy exposed and ready to be fucked. She had a short coat of brown hair covering her slit, matted down with a combination of pussy juices and dog semen. Pussy hair is usually a turn-off for me, but I wasn't about to let that stop me. I lifted her ass a little higher into the air so that she was standing on tip-toes, aligning her snatch with my cock, which I promptly buried into her. The inside of her vagina was still slick with Toby's cum, which allowed me access with no difficulty. Her pussy had been stretched from the knot as well, which meant I barely felt anything as my dick slid inside her, but just the thought that I was fucking my girlfriend's stuck-up sister made the feeling exquisite. I pulled my cock almost all the way out, then plunged it back into her with reckless force. An involuntary groan escaped Melissa's lips as I thrusted in and out viciously, pounding her pussy as hard as I possibly could. "Yeah... you like that, you little whore?" I asked between breaths. Melissa was silent, so I grabbed her by the hair and pulled her head backwards. "Tell me you like it." "Y... uh... I... I like it!" She managed through groans of both pain and pleasure. "What do you like?" "I... I... I like you... oh... fucking me!" I grinned; it may not have been sincere, but the little bitch was beginning to get it. I continued ramming my dick into her, completely lost in what I was doing. I was deriving more pleasure from causing Melissa's humiliation than I was from actually fucking her. Either way, it felt amazing and I knew I wasn't going to last much longer. "You ready to take my load on your face?" I growled, "You're a little slut, and sluts love cum on their faces, right?" "Yes," Melissa groaned, "I want your... c... cum on my face..." I pulled out of her and spun her around on the pool table, then shoved her onto the floor on her knees with my member in her face. She got the message and began sucking me off again, her tongue lapping up both her own juices and her dog's cum. Again, it was more the thought of what was happening than the actual feeling that sent me over the edge. I pushed her off of my cock and forced her head back so that she was looking me in the eye. I was expecting her to close her eyes in anticipation of what was coming, but she seemed determined to keep glaring at me throughout. I groaned as I came, and the first spurt of semen shot over her head and onto the floor near Toby. The second strand landed right in the middle of her forehead, and the third hit her cheek and splashed up into her right eye. I was breathing heavy as my orgasm subsided, and I looked down at Melissa's tear-stained and cum-splattered face as she attempted to rub the cum out of her eye. "Well," I said, stuffing my softening dick back into my pants, "That was fun, but I really should get going." I slung my camera bag over my shoulder. "You, uh... might want to clean up in here." I motioned towards the floor, which was sticky with mine and Toby's cum. Melissa said nothing; she just glared at me, sniveling. I turned on my heel and proceeded to head up the stairs, but stopped on the first step. "Oh, Melissa..." I called back. I got no reply, but continued anyway. "Shave for next time, will you?" "Next time?!" I looked over my shoulder to see the mortified look on her face, as well as to take another quick gander at her naked body. "Of course," I said, smirking. "Unless, of course, you want everyone to see what a little slut you are..." Melissa just stared at me for a moment, at a complete loss for words, then suddenly broke down sobbing. I had no idea when or if there would ever be a next time, but I wanted to cause the bitch as much torment as I could, so I left it at that, and headed up the stairs, leaving a broken Melissa, crying and covered in cum. I didn't look back. TO BE CONTINUED?
