Note 1: This is a 2013 Earth Day Contest Story so please vote. Note 2: A special thanks to MAB7991 for editing this and so many of my other stories. MY BROTHER, MY MASTER Kevin slammed his hard cock inside my wanton pussy. My pussy tightened around his cock hungry to feel his hot seed explode inside me. "Harder, fuck me harder," I begged, each forward thrust getting me closer to my own orgasm. "Come for me sis," he grunted, slapping my ass. Obeying like I always did, I frantically rubbed my hard clit as he pounded me hard and fast. "I'm cloosssse," I moaned. "Now slut," he demanded. "Fuuuuck," I screamed, as my orgasm and his hit simultaneously. His cum exploded into me as my juices fought to get out. A couple of minutes later as we both recovered from our orgasms, Kevin smiled, "Happy Earth Day." I laughed, "Happy Earth Day to you too." As I waited for the traditional ass fuck that was too follow, I reminisced to twenty years ago when we started our incest relations in the Amazon rainforest...on Earth Day. ..... "You are not serious?" I asked, dad's words so ludicrous that I was sure I must of heard him wrong. "Yes, Kerry, it is time we get away from the twenty-four seven plugged in world you and Kevin are so obsessed with," dad explained. Sarcasm dripping from me, I retorted, "It's not the eighties anymore, dad." "Well for two weeks it will be the eighties, the eighteen eighties," he replied back quickly, with his usually corny humour. "Mom!" I said, looking for help. There is no way she liked this idea. She hated camping, there was no way she wanted to go to Amazon rainforest. "Your dad is right. It will be good for you and Kevin to go see another part of the world," Mom answered, before adding, "your brother is excited about the trip." "Of course he is," I quipped sarcastically, glaring at him. It was hard to believe that we had any of the same DNA, despite the fact that we were twins. "Plus it will be a great way to celebrate Earth Day," Dad added. "What day?" I asked. "Earth Day," Dad repeated as if that made it clear. "Earth Day is not a real thing," I argued. "Of course it is," Dad said, clearly beginning to get annoyed by me. "It's not a real holiday if we have to go to school," I pointed out. "Well this year you will be missing school on Earth Day," dad shrugged, smiling at his wit. Twenty more minutes of futile protest landed on deaf ears and apparently instead of doing something cool like going to the mountains, or a beach in Mexico, we were going to the Amazon rain forests. To make matters worse, I would be celebrating my eighteenth birthday on a plane on our way to a foreign country with my family....my life officially sucked. ..... The trip there was exhausting as flights were delayed, food was terrible, and I was on the tail end of my period. Because I was miserable and unhappy with this whole trip, I was a complete whiny bitch the entire time. I was clearly getting on my father's last nerve and it made me try even harder to push him over the edge. My mother, meanwhile, just acted like the journey to hell was all fine and dandy. To make matters worse, Kevin and I celebrated our 18th birthday in an airport. Mom and dad tried to make it memorable, but I wouldn't let them. I was pissed off; I should have been celebrating my birthday with my friends not stuck at an airport while our flight was delayed by six hours. When we finally got onto a plane, a day later, I wished I was back in the airport. The flight was on an eight-passenger plane and had me a nervous wreck. Clearly not the time to learn you may be claustrophobic. I actually held onto my brother and when we hit some turbulence, my hand actually landed directly on Kevin's very hard cock. I quickly moved it away but two things instantly popped into my head: 1. Was he hard because of me? 2. Wow...by brother was well-endowed. The look of embarrassment on his face was hilarious. I just shrugged and said, "Oops." He didn't say anything, clearly mortified by having his hard cock felt by his sister. Somehow though it relaxed me as I was no longer worried about the tiny plane crashing as I became fixated on just how big a cock my nerdy brother had. Deciding to entertain myself during this brutal day, I whispered in his ear, quiet enough no one else could hear, "Was baby brother hard because of me?" When he didn't respond, I pushed further, curious if I could provoke an even deeper shade of red in his cheeks. I asked, my tone soft and seductive, "Does my baby brother want to fuck his sister?" Apparently there was another shade as Kevin's eyes went big at the question. "You're a virgin, aren't you, baby brother?" I asked, very confident I was right, this time purposely allowing my hand to land briefly on his stiff cock. He gasped as I gave his cock a solid squeeze. He finally spoke as he asked, "Kerry, what are you doing?" "Just bonding with my brother like mom and dad suggested we do," I smiled back, my hand still on his cock that just flinched in my hand. "Hmmmmm, am I getting you excited?" "Kerry, stop," he demanded quietly, although he never attempted to move my hand. "So what made your snake come alive?" I asked, slowly rubbing his cock through his jeans. "I-I-I don't know," he stammered clearly distracted by my teasing. "I think I do," I purred, as I began to rub his cock faster. "Oh God," he groaned. "Come for your sister, baby brother," I whispered in his ear, giving a quick nibble on his ear lobe. A few seconds later he let out a strange, noise as he came in his pants the whole time biting his lip so as to not let out a sound that would make what he just did obvious to the other passengers and especially not to our parents. I moved my hand away, put my headphones on and closed my eyes amused as hell. At that moment, I still had no intentions of fucking my brother, it was just harmless fun, but apparently, I had planted the seed for him to want to fuck me whether I intended to or not. We arrived jet lagged, and each of us snappy and needing sleep. Yet, we still had two more hours to travel by vehicle with others. We were squished into a compact bus where I had to sit on my brother's lap the whole time. It was like the Gods of incest where manipulating our situation from above. Kevin and I were in the back with an older couple. Once we got started, the journey was a bumpy one and I learned rather quickly that my brother: 1. Has a quick recovery time. 2. Got hard having his sister on his lap. It probably didn't help that I purposely ground my ass onto his crotch every time we hit a bump. I wondered if I was wearing my cheerleader skirt right now, could I ride his cock during the long bumpy journey. As soon as the thought popped into my head, I realized I was thinking about fucking my brother. I shook my head at the silly thought and yet the slight dampness in my pussy was impossible to deny. I glanced at the older couple and saw they were both asleep. Trying to drive my horny brother crazy, I leaned back into him and whispered, "They are asleep. Why don't you just pull that big cock of yours out of your jeans and let me ride you, baby brother?" I wasn't being serious and was taken by surprise when he said firmly, "Get up." "Pardon?" I asked. "Get up so you can touch it first hand, big sister," Kevin ordered, his confidence coming out of nowhere. "I was just teasing you," I replied, suddenly realizing I may have gone too far. His hand went directly to my crotch area and as his fingers touched my pussy through the thin fabric of my shorts as he said with a smug smile I had never seen him use on me before, "Looks like you were getting off dry humping me." "Stop, Kevin," I weakly protested, even as I moaned lightly, defeating any pretense that I wasn't getting turned on by my brother's touch. This time he whispered in my ear like I had him earlier, all the while his hand was firmly on my now burning pussy, "I think big sister wants her brother's big cock in her." I stammered, "W-w-what, I-no-I." Even as I protested, the sudden transformation of Kevin was an instant turn-on as I liked my men to be in control. "Your words say no, but the wetness in that hot cunt of yours and the hunger in your eyes say yes, yes, yes," he replied, a confidence and cockiness in him I didn't know existed underneath his nerdy exterior. Also, hearing my brother who can recite verbatim every word of The Lord of the Rings movies saying cunt was shocking...and had my pussy literally ready to burst. I tried to regain control of the strange power shift that had just occurred. "Do you want me to pull my shorts and panties to the side and ride your cock, baby brother?" He laughed but a cocky laugh, "No, no, you need to earn my cock." "Excuse me?" I questioned stunned by his answer. "Actually, for now you can straddle my leg and get yourself off like a good little slut," he said. "That is enough..." I began, but he put his finger to my lips. "Ssshhhhh, my sister slut, you wouldn't want everyone on the bus to know that you are cock hungry for your brother's cock. Now stop pretending you don't want this and get yourself off...NOW!" I couldn't believe the audacity of my nerdy brother, nor could I believe just how turned on I was. Part of me wanted to slap him silly, to let him know I am the one in charge; yet a larger part of me wanted to obey him and an even larger part of me was dying to get off. I felt my body reposition itself and lower down on his leg. After a brief hesitation, I began grinding my pussy onto his leg like the slut he said I was. He whispered, "Good girl," which both humiliated me and at the same time turned me on. I closed my eyes and just allowed myself to enjoy the submissive task, ignoring who was controlling me, getting closer and closer to orgasm. As my breathing began to increase my brother surprised me again as he held onto my hips. "Stop," he ordered. I did and looked back at him. "Why?" "Because you need to earn your right to come, my slut," he informed me, before adding as my mouth dropped open at his answer, "I think we are about to arrive." I turned to look ahead and indeed we were slowing down. I moved off Kevin's leg, my pussy wet and still needy and glared at him as I whispered, "Don't you ever call me a slut again." Kevin smiled, put his hand to my pussy and returned, "Big sister, you are a slut, my slut and I will call you slut and whatever else I want." I let out a moan at his touch, my pussy so close to eruption, and noticed the old man watching like a pervert. Impulsively, I winked at him and deciding to play along with my brother for the old man. I put my hand on Kevin's cock and said, "May I come, baby brother?" He chuckled, as he moved his hand away, "We're here." The bus stopped and I was frustrated as Hell. We got off the bus and mom asked me, "Are you ok, dear?" "W-w-What? W-w-Why?" I stammered. "Your cheeks are really red," she said, concerned and felt my head. "You are a little warm." "I-I-I'm fine," I struggled to get out, mortified that mom might catch on I was burning up all right, and explained, "the bus was a sauna Mom, just one more disaster on this trip of disasters." Mom sighed, as I acted like my normal bitchy self and went to dad. Kevin walked up behind me and whispered, with a chuckle, "Nice cover, sis." "Fuck you," I snapped back. "All in good time," he retorted smugly and walked away, leaving me with a thought I had never, ever seriously considered...until now...fucking my brother. ..... The next two hours was spent hiking and it was exhausting as the heat was unbearable. On top of the heat, my brother drove me nuts as he ignored me completely and was his usual nerdy self, talking to dad about the environment and what different animal species we may find on our trip. Finally, we arrived where we were staying that night...in FUCKING tents. I asked, my tone implying my disgust, "We are not sleeping here?" Kevin talked for the first time and it dripped with sarcasm, another thing I didn't know existed in him, "No Kerry, the five star hotel is just over that hill." "Fuck you," I snapped. "Language," my mother said robotically. Dad said, "Just embrace nature, sweetheart." I quipped back, "I want to embrace my cell phone." Kevin suggested, his words full of innuendo our parents wouldn't understand, "Yes, big sis, we are in a new world, embrace new things, try things you have never considered before today, just let yourself go and submit to what you really desire." My face went red at the innuendo as my dad agreed, "Exactly, just free yourself of all the crazy social expectations of home and just let go." I laughed softly as dad was vaguely agreeing that I should fuck my brother, which right now was beginning to seem like an increasingly good idea. My period gone, I was horny as hell. Kevin's sexual teasing and shocking aggressive behaviour had me in a sexual state that hadn't completely simmered. I finally agreed, looking at Kevin, as I asked dad, "So I should try new things and allow whatever COMES to COME?" "Exactly sweetheart, what a great philosophy, allow whatever comes to come," dad agreed excitedly. Kevin couldn't hold back a laugh as he agreed, "Yes be sure to take everything that comes your way, no matter how big and hard the obstacle." Keeping up with the dripping innuendos, I countered confidently, "I love obstacles to be long and hard, to push me to places I usually wouldn't go." "That's the spirit, embrace the challenge," dad said beaming with parental pride. "Challenge accepted," I said, staring directly into my brother's hazel eyes. "Challenge doubly accepted," Kevin countered, his nerdy smile suddenly sexy. "Rad," Dad said, still stick in his eighties slang. "I knew you would get into it once we got here." Dad went to get some food ready leaving Kevin and I alone. "I can't wait to get into it," Kevin said. Playing coy, I retorted, "I'm not sure you would know what to do if you did get into it." He moved towards me, sauntering confidently, as he continued, "So many holes to fill and so little time." "You're bluffing," I countered, my pussy tingling at the possibilities and his cockiness. "Let's go for a walk," he said. Calling his bluff, I said, "Lead the way, Master," playing flirtatiously. "Master, I like that," he nodded, before turning to our parents, "Mom, dad, Kerry and I are going for a walk." "Sounds good, but stay on the paths and be back in an hour for dinner," Dad said. "Will do," Kevin agreed, grabbing my hand and leading me to the path. Once out of our parent's sight, I asked coyly, "Are you taking me somewhere secluded to ravish me?" "Something like that," he responded, his tone implying duplicity. I followed curious and horny, although I was still convinced he was just playing me, like I was him. As we walked along, I pondered, 'What if he is serious? Would I actually commit incest with my brother? His cock sure seemed impressive hidden in his jeans, and I do love a big cock, but he is my brother, my nerdy brother.' I was pulled back from my strange conversation with myself when Kevin eventually stopped and said, "This is perfect." "What is perfect?" I asked seeing nothing out of the ordinary I hadn't seen the past ten minutes of walking. "This place," he said, surprising me once more as he unbuckled his belt and pulled his pants down. His hard cock outlined in his blue briefs. "What are you doing?" I gasped, knowing full well what he was doing just not able to fully believe all the innuendo had been more than just harmless teasing. "Making my sister, my slut," he answered. "Excuse me?" I asked, surprised by his frankness and name calling, even as my panties got undeniably damp. "Stop playing innocent. Your mouth is literally watering, I can see it from here. Plus, your cunt is probably soaking wet like it was when you were humping my leg," he confidently assessed. "That was just playful teasing," I said, even as I stared at his cock in his underwear. "Was it?" He asked, "Your red cheeks and moaning seemed to say something else." "It was a sauna in there," I defended. "We'll that could defend the cheeks, but not the moaning or the wet spot you left on my knee," he countered. "I did?" I asked, surprised. "Want to smell?" asked, pointing to his knee. "No, I think I am alright," I replied. "Now come and suck my cock," he ordered, pulling down his shorts and revealing seven solid inches of hardness. My pussy leaked slightly at the sight of my brother's cock, but I pretended otherwise. "In your dreams." "No, in my dreams you and Carla are in a lesbo sixty-nine and I saunter in and make you both my cheerleading sex slaves," he countered, slowly stroking his cock. "You pervert," I shot back. Carla was my best friend and cheerleading captain, and although she was gorgeous, we had never dyked out. "You're the one drooling over your brother's cock," he said. "You're the one who wants your sister to suck your cock," I shot back, even as I imagined his cock shooting his load down my throat. Although common among girls, most give head because it is expected not because they like it, as for me I love it. I loved a cock growing in my mouth, loved the stiff warmth in my mouth and loved the unique taste of cum, every man different, even each load from the same guy subtly different. "Funny how you didn't deny you are hungry for my cock," he continued. "Funny how you can't get laid so you think you can bully me," I countered, trying to one up him. "I have been laid many times," he answered, surprising me. "As if," I quipped. "I lost my virginity to Mrs. Sheets and the band trip at Christmas was quite the learning experience. Apparently that American Pie chick wasn't lying about band chicks," Kevin revealed. I gasped. Mrs. Sheets was mom's best friend and married to a handsome lawyer. "Bullshit," I said, calling his bluff. He shrugged, "If I had my cell I could show you some photos. She is an amazing cocksucker, you could probably learn a thing or two from her." "I have never had any complaints," I shrugged. "Well let me compare, on your knees my sister slut," he ordered. Part of me wanted to slap him in the face, but a bigger part of me wanted to obey. His cock looked so deliciously appetizing. "This is a onetime offer, sis," he said. "On your knees now or forever hold your peace." Letting go of my moral issues of incest, I moved towards him and dropped to my knees. "Good girl," he said, holding his cock for me. "You are turning me into a bad girl," I teased, reaching for his cock. "My bad girl," he firmly clarified. "Mmmmmm, you are so naughty, Kevin," I purred, his throbbing cock in my hand. "You have no idea," he smiled ominously. "Now suck your brother's cock." Unable to deny the forbidden fruit any longer, I opened my mouth and took his mushroom top between my lips. The soft moan from his mouth made me smile around his cock as I shifted the power back to me. I was now in control and I revelled in that power. I swirled my tongue around his cockhead, recalling his words that Mrs. Sheets was an amazing cocksucker and deciding to prove to him I was better. I realized as I began to slowly move up and down the first couple of inches of his cock that I was trying to prove to my brother I was a good cocksucker, but ignored the ridiculousness of it and focused on giving him an amazing blow job. My Brother, My Master "Hmmmm, you are quite the tease," he moaned as I bobbed slowly back and forth taking just over half his cock in. I moaned on his cock as I began slowly taking his cock in my mouth. After I had half his cock in my mouth, I began slowly bobbing back and forth, each forward movement taking more of my brother's stiff rod in my mouth. "That's it cocksucker, nice and slow, worship your brother's cock," he moaned authoritatively. I obeyed, the name calling somehow triggering a wetness in my pussy I couldn't explain. My left hand went to my wetness under my shorts and I began rubbing myself as I continued taking more of his cock in my mouth. A couple of minutes later, I had six inches of Kevin's thick rod in my mouth and was determined to take it all. Kevin grunted, "Do you think you can take it all slut?" My fingers frantically rubbed my clit as I focused on getting the last inch in my throat. I leaned forward, gagging slightly as I took the last of Kevin's hard cock on into my throat, my nose buried in his pubic hair. I lingered there impressed I had taken all of him and for some reason wanting to impress my brother. "Shiiit, you did it cocksucker. Now get me off like the dirty incest cum slut you are," he ordered. I had always been treated like a princess so I couldn't believe the litany of derogatory names he threw at me. I should have been furious, yet it only turned me on more for some unknown reason. I hungrily bobbed up and down desperate to get him off, to taste his cum. Unlike all my friends, I liked the taste of cum, enjoyed the odd texture lingering on my tongue and liked the aftertaste that lingered long after the deed was done. I was again surprised by my brother's transformation from meek to mighty when he ordered, "Stop rubbing yourself slut. You only get to come after your Master does and only if I decide you deserve the privilege." I couldn't believe what I was hearing, yet I obeyed as I quit rubbing my needy pussy my building orgasm just below the surface, a volcano ready to burst on a moment's notice. I continued my aggressive assault on my brother's cock all the while trying to figure out why I was obeying him and why it was turning me on so much. The word 'Master' was also a shock that sent a chill up my spine. It was another ludicrous word out of my brother's mouth and yet it again enhanced my eagerness to play, my hunger to come. "I'm close, cocksucker, don't you drop any of your Master's cum," he ordered, through stunted breathing. My head bobbed like I was in the Olympics speed cocksucking finals and I was determined to win the gold medal. "I'm coming," he grunted before I felt his full load of sticky goo glide onto my tongue and down my throat as if my lips, tongue and throat were made perfectly for his cock. As rope after rope filled my mouth and slithered down my throat and into my belly. I continued my hungry cocksucking, wanting, no craving, more of his addictive cum, a taste like nothing I had ever tasted before...salty, sweet and bitter. A couple more minutes of retrieving every last drop of Kevin's cum, he pulled his cock out of my mouth. As he pulled his underwear and jeans back up, he said, not recognizing my need to come or of him acknowledging just how amazing I was, "We should probably get back before mom and dad come looking for us." I couldn't believe it, I just blew my brother and now he was acting as if nothing happened. I wearily got up and Kevin started walking back the way we came, leaving me behind. Pissed off and horny, but also worried if I didn't follow him I may not find my way back to camp, I quickly composed myself and reluctantly followed. As we silently walked back through the forest, I decided two could play this game. I would ignore him as well, I was the popular one, and he was the geek. Yet, no matter how much I tried I couldn't get my brother's cock out of my head. Also, no matter how much I tried to cool down my fevered cunt, it kept begging for attention. I knew I had to come so I could focus and stop thinking of my brother's yummy, hard, long, and thick, cock and how good it would fit fucking my needy, wet cunt. Just as we were arriving back to camp, Kevin turned to me and finally spoke. "I know your cunt is probably leaking like a funnel, but don't you dare come until I give you permission." Before I could respond to his condescending expectations, he turned and left me alone. I was furious at his treatment of me, yet another gush of wetness soaked my panties. I again followed him and was about to yell at him when I heard mom's voice ask, "Where is your sister?" "Right behind me," Kevin answered. My frustration and anger boiled but I had to hold it all inside until I was again alone with him. The rest of the night was exhausting as my pussy eventually cooled down but never completely, causing me lots of anxiety. Meanwhile, Kevin was his usual geek self as he and dad talked about the environment, the rest of the trip and eventually about how excited they were that they were making three more Star Wars movies. I gave Kevin a plethora of glares throughout the evening, but he seemed oblivious to my anger. At bedtime, I learned much to my surprise, that I was sharing a tent with Kevin. I was looking forward to being alone so I could finally get the release my body had been craving for hours. Kevin, a smug smile on his face, asked me, "Ready for bed, sis?" Mom and dad, of course, didn't notice the smugness. Wanting him alone to set him straight, I faked a yawn, "I guess so, baby brother." I stressed the word baby as I tried to re-establish the sister-brother hierarchy that had been in place since birth. I was in charge, not him. Ten minutes later, both of us in the tent, Kevin said, "Damn it is still hot." He stripped down to his underwear and looking at me asked, "Does my cocksucker need a bedtime snack?" I hadn't realized I had been staring at his crotch area and his semi-erect cock outlined so well. Snapping out of my sudden hunger to suck his cock again, I said firmly, "This has got to stop." "What does?" He asked innocently. "You fucking know exactly what," I snapped. He shrugged, as he lay on top of his sleeping bag, "I just thought you might be hungry." His casual attitude frustrated me even more. "We are never doing that again." "Whatever," he said, closing his eyes. "You are such an ass," I shot back. He opened his eyes, looked into my eyes and asked, "Did you say you wanted it in your ass?" "Fuck what the hell has gotten into you?" I asked, super frustrated by his new attitude. "The better question is what do you wish was in you," he countered. I gasped again not able to believe the complete cockiness of my usually quiet, meek brother. "I am going to sleep, if you decide you need a bed time snack I will leave my cock out for you," he said, tugging his underwear down and unleashing his still semi-erect cock. "Or if you need to relieve yourself of your hunger down below feel free to just climb on top and get yourself off." He closed his eyes, smiling, his cock now totally hard stood at attention causing another gush down below. Staying strong verbally, even as my body ached in longing. I said confidently, "That is never going to happen." "Your loss," he said, not even opening his eyes. A few seconds later he said, "Good night, my slut." "Stop calling me that," I snapped. "Do you prefer cocksucker?" He asked, opening his eyes again. "Enough," I demanded, holding onto the last shreds of dignity I had left. "This ends now." "Whatever you say," he said, again closing his eyes, although his smug tone implied he thought he was still in charge. "I'm serious," I countered. He didn't respond and I closed my eyes, desperate to win this power struggle. The next ten minutes were literally hell. Angry at my brother's pretentious, confident attitude mixed with an undeniable and unexplainable lust for him. I kept taking quick glances at his still very erect and ready for action cock and cursed its beauty. My pussy was leaking, the fire was burning and my moral fibre was dissolving rapidly as my hunger for his cock was overwhelming my very being. "It's now or never, my slut. If you want to come tonight, Crawl over to your Master and get my cock ready for that cunt of yours," Kevin said, never opening his eyes. I looked at his cock, beginning to shrink and before I even knew what I was doing I was obeying my brother's orders, verbatim. I crawled to him, leaned forward and took his cock in my mouth determined to restore it to all its erect glory. Even as I pleasured his warm cock I pondered why I was doing it. Yet, the answer was obvious; I wanted and needed his cock in me. "Good slut," Kevin moaned, "I knew you couldn't resist." I could feel the heat in my cheeks, he was right I couldn't resist. My insatiable hunger was all that mattered. Unlike last time when I was hungry to make him come, this time I wanted to tease him. I used my tongue and moved down slowly to his balls, taking each in my mouth individually, before returning to his stiff cock. A couple of minutes later, Kevin asked, "So what does sis want to do next?" Taking control, I straddled his cock pulling my panties aside and lowered myself onto his erection. "I want to ride your big cock, baby brother," I answered, as I leaned down and kissed him. As his cock filled me, I allowed myself to enjoy being filled so completely as my tongue explored Kevin's mouth. For a couple of minutes, there was no movement other than our lips and tongue as we gave in completely to our sin. Finally, he broke the kiss, again trying to take control. He put his arms behind his head and ordered, "Take off your t-shirt, I want to see my slut's tits." I sat straight up, his cock going deeper into my wet cunt, and asked coyly, as I ground my pussy on him, "You want to see your sister's tits, do you?" He grabbed my hips and thrust upward forcing out an undeniable moan. "Now, slut." Overwhelmed with hunger and enthralled by my brother's dominant power, I quickly pulled off my t-shirt allowing my firm breasts and hard nipples freedom. "Nice tits, sis," he complimented as he pulled me down and my left breast went into his mouth. The warmth of his mouth on my breasts sent chills up my back and sparks down below, my burning need to come becoming impossible to deny. My head was spinning, my body burning as my breathing became erratic. I began slowly moving my hips to fuck myself on his cock as he pleasured my breasts with his lips, tongue and teeth. He whispered, "That's it slut, fuck yourself like the little slut you are." Again such words should have been offensive and yet instead turned me on more. I whispered back, "You want your own personal live-in slut don't you?" "If you are worthy," he quipped back, just as I began riding his cock faster. Trying to take control once again, I leaned back, grinding my pussy on his cock and allowing myself to be filled completely. "Do you like my tits, big brother?" I asked, calling him big brother for the first time. "They are very nice," he nodded, as he watched me cup my breasts, as I bounced up and down on his cock feeling so full. "Just nice," I pouted. "They are not as big as Mrs. Sheets," he replied. "You're an ass," I shot back, grinding my pussy on his cock. "Soon I'll be in your ass," he smugly retorted. "That is an exit only area," I countered back. "We will see about that," he smirked, lifting me up and flipping me onto my back all the while keeping his cock in me. "Oh God," I moaned, as he manhandled me with such power and authority. Looking down on me he said, his cock deep in me, "You are my fucktoy now sis. Your mouth, cunt and ass are mine, is that clear?" "Just fuck me," I replied, ignoring the question. "Answer the question, my slut," he repeated, his cock deep in me, but not moving. "Damn it, Kevin, just fuck me hard," I begged, moving my hips to fuck myself on his cock. "Obey," he said firmly, grabbing my hips and holding me in place. "Please," I begged, not wanting to give in to his absurd expectations, but desperate to reach my long delayed orgasm. "Please what," he smiled, his cock somehow flinching inside me. So desperate to come, I heard the words out of my mouth before I had time to think about them, "Please make me your slut." "Real sluts take in the ass," he clarified. Again so desperate to please, to come, I responded without thinking, "My ass is yours, big brother." "Good girl," he purred, which for some reason actually only made my submission to him hotter. Getting into the role playing I responded, "I am here to serve my Master." His smile getting wider, he returned to slow hard strokes which continued kindling the flame but refusing to allow it to grow to a full scale furry. "Oh yes," I moaned, "Harder, fuck your sister harder." Hearing the words made the taboo act even hotter. "On all fours, slut," he grunted. I didn't hesitate, so drawn into his world of submission and my need to come that it seemed natural to obey. "Good girl," he again approved of my obedience, my pussy juice literally leaking out of me in this position. I felt his fingers slip inside my pussy and after three quick pumps, he pulled them out and moved to my ass. I instinctively tightened up as I realized his intent. "Relax, slut," he instructed as his finger teased my anal entrance. I asked nervously, "Did you fuck Mrs. Sheets ass?" "Of course," he answered, "she was reluctant at first too, but true sluts have three holes and all three are meant to be used." Strangely in my erotic state that logic made sense, plus if Mrs. Sheets could do it so could I. In retrospect, a bizarre reason to do something, but suddenly pleasing my brother, my master, and allowing him to take my anal cherry seemed the right thing to do. "O-o-ok," I stammered nervously, yet excited at the possibility of pleasing Kevin. "Ok what my little plaything," he answered, continuing to draw me deeper into his obedience web. "Fuck my ass, Kevin, take my anal virginity with your big hard cock," I replied, trying to shock him, trying to get him to just take me, my need to come all that remained. "Quite down, slut, or Mom and Dad will be witnessing you taking a cock up your ass," he said, his tone more amused than warning. Remembering where we were and what we were doing, I obeyed and whispered, "Sorry Master, please make me your slut." He laughed as his finger penetrated my back door making my one way only rule no longer relevant. I winced slightly at the intrusion but was surprised how the slight pain faded almost as quickly as it came. "Now I am going to prep your ass for my cock, sis. Just relax and this will be good for both of us," he explained, his tone shifting from domineering to soft and soothing. "Kkkkk," I whimpered, his finger wiggling inside my ass. "This is called gaping," he explained. The thought of my brother teaching me sex lingo would have been hilarious less than twenty-four hours ago, yet at this moment I was completely at his whim. "Kkkkkk," I again barely got out trying to get used to the strange, uncomfortable feeling inside my ass. The next few minutes my ass was slowly widened as Kevin eventually slipped in a second finger causing a new burning that didn't fade as quickly as the first. The whole time Kevin kept talking, explaining what he was doing, calming my nerves, relaxing me when I should have been anything but relaxed. Eventually I got used to the two fingers and although the burn never completely dissipated, as I relaxed I began enjoying the absurd submission to my brother. Finally, wanting to feel his cock in my ass, I whispered, "Fuck my ass, Kevin." As his fingers left my ass, I suddenly felt empty. It didn't last long as I felt his hands back on my hips, and his cockhead between my ass cheeks. "Are you ready to give your ass to me, slut?" he asked, his tone back to authoritative. I didn't hesitate as I moaned, "Fill my ass with your cock, Masteeeeeeer." He didn't wait for me to finish my answer before sliding his cock inside my ass. "Relax," he instructed, as his cock slowly moved deeper inside me. "It huuuurts," I whimpered, the pain much more intense than his so-called gaping earlier. "The pain will go away," he promised, as he continued his slow intrusion in my no longer virgin ass. "Shit," was all I could counter with. Silence persisted as I bit my lip trying to deal with the incredible discomfort in my ass as his cock went deeper than his fingers ever did. I let out a gasp when he announced, "All in, big sister." "I am sooooo full," I whimpered, shocked and yet proud to have taken all his cock. "Just let yourself get used to a big cock in your ass, sis," he explained. "Kkkk," I obeyed, the pain still blunt and yet the thought of Kevin fucking my ass turning me on at the same time. A minute later, Kevin said, "I'm going to slowly start fucking you Kerry." Hearing my name after the name calling and sister references was startling and intimate. "Ok, Kevin, please be gentle." My whole body burned, a mixture of pleasure and pain, as his cock slowly pulled out and pistoned slowly back in and out again. The sensation was unlike anything I had ever felt before, a feeling of hunger, of crazed desire, that made me want more. After a few slow strokes, I moaned, "Faster Kevin." "Tell me exactly what you want, slut," he demanded. Falling into the submissive nature that I didn't really know existed before today, I responded, "My ass, Kevin, fuck my ass." Obliging, his strokes in and out of my ass picked up speed and the burning sensation began to fade as the pleasure pulsations began to increase. I wanted more, I needed more and begged, "Harder, Kevin, fuck your sister's ass." "Who owns your ass, Kerry?" he grunted, as his cock slammed into me. "Yooooooou do, Maaaaster," I admitted through a long moan as a renewed sharp pain trembled through my body even as a new rush of pleasure cascaded through me simultaneously. "And you will obey me at all times," he questioned, pulling his cock almost all the way out of my ass. "Yeeeessss," I agreed, not even thinking how big a scope such an agreement may encompass. "Your mouth, cunt and ass are mine to use as I wish?" as he continued his clear domination of me. "They are all yours, Master," I agreed, desperate to feel his cock back in my ass. "Ready to come, my ass slut?" he asked, his cock just barely in me. "Yes," I whimpered, so hungry to feel him in me and to reach my long simmering orgasm. "Fuck yourself, slut," he ordered. I didn't hesitate realizing I was finally going to be in control of my own orgasm. I slowly backed my ass onto his cock, taking it all back in my ass. Once all in, I slowly moved back and forth getting used to fucking myself. Once in a constant rhythm, I began moving my ass back faster, filling myself completely, even reaching new depths in my ass, causing new sensations of pleasure and pain. The pain somehow enhanced the pleasure, making me feel dirtier, hornier and more desperate to come. My orgasm continued to build and bubble, just below the surface of explosion. Frustrated, I realized what was missing, Kevin's nasty words. I begged, as I began slamming my ass back onto my brother's big cock, "Tell me what I am Master." I could sense his smug smile without looking as he assaulted me with names: "Ride my cock ass-slut; pound yourself like the hungry little slut you are; fuck yourself on your brother's cock like the incest slave you are; your cocksucking lips are mine, your big titties are mine, your cunt is mine and your tight ass is mine." The litany of names was the final pin that burst the bubble and my orgasm bubbled over the surface as my moans and whimpers began to rise as well. The eruption came when he finished his verbal assault with, "Now come sister slave, come for your Master, come now my cunt, my slut, my slave." My Brother, My Master "Fuuuuuck," I moaned, biting my lips to not scream and alert my parent's to their children's sexual debauchery. The orgasm riddled through me unlike any that I had ever experienced, realizing my previous sexual past was just a charade of real pleasure. Collapsing forward, weak from the never ending earthquake of pleasure, Kevin began pumping his cock hard into my ass somehow enhancing even more my orgasm. I babbled like a blithering idiot, "Oh God, shit, fuck, cum, God, oh, shit, yes, more, aaah, harder, fuck, fuck, I love youuuuuuu." I couldn't believe I declared such a thing as my brother took my anal cherry, yet at that moment I was his and wanted him to know just how much I wanted to be his unconditional slave. "I love you too, sis," he grunted, as I felt my ass being filled with his cum. "Oh yes, fill my ass with your come, Kevin, it feels so good," I moaned, loving being used as his cum bucket. I tightened my ass as best I could to milk every drop of his cum. "Shit you are so tight and eager, slut," he grunted, as he slowed down and eventually pulled out. Wanting to show him just how much of a slut I was for him, as soon as his cock left my ass I turned around and took his cock back in my mouth and retrieved any last remnants of his cum. "Fuck sis, you really are a bigger slut than I thought," he groaned, looking down at me. Taking his cock out of my mouth, I looked up and said, giving his delicious cock a firm squeeze, "Your sister slut, big brother." Finally, both exhausted, we collapsed to the ground and into each other's arms. After a couple minutes of silence, I whispered, "I can't believe we just did that." "It's just the beginning," he promised, kissing the back of my neck. "I hope so," I whispered back, knowing that there was no going back, nor did I want to. "By the way, happy Earth Day," he said, moving his mouth to my ear. "There really is such a thing," I laughed. I felt his cock, still hard, poking between my legs, as he said, "I think we have started a new tradition for Earth Day." "We have, have we," I purred, reaching behind and grabbing his hard cock and guiding it into my very wet and yet feeling rather neglected pussy. "I guess there is one hole of mine I haven't filled yet, have I my sister cum bucket," he said, his cock sliding easily inside my cunt. ..... Remembering our first Earth Day all those years ago, my first time submitting submissively to my brother in the rainforests of the Amazon, had my pussy soaking wet and my ass begging for attention. I reached for his semi-erect cock and began stroking it back to fullness. "Ready for round three, big sis?" he smiled. "Always," I smiled, getting onto all fours. "No, no, this time I want to try something different," he smiled, standing up, grabbing a chair and sitting on it. "What do you have in mind?" I coyly asked. "Straddle me and ride my cock with your ass," he instructed. "Really?" I asked, thinking this virtually impossible. "You may want more lube," he suggested, ignoring my question. Knowing his tone meant the conversation was done, I grabbed the lube and generously coated his cock. After adding excess lube on my ass, I slowly straddled the chair and lowered my body down. Finding his cock, I aimed it at my ass and slowly lowered myself onto his cock. Although awkward at first, I slowly took all his cock in my ass, the feeling in this position a new sensation. Once all in, I began riding his cock slowly as I got used to the fullness and angle. "Good girl," he purred, as I finally got in a comfortable rhythm. "Fuck, this is awesome," I moaned, as I began to really ride his hard cock. "Bounce," he demanded. I obeyed, allowing my whole body to collapse on his cock and allowing his cock to reach new unimaginable depths inside my ass. "Oh shiiiit," I whimpered, as the mixture of pleasure and pain, long gone after years of backdoor fucking returned. "Harder, slut," he ordered. Again I obeyed, whimpering like a virgin school girl as I devoured his cock with my ass. A few minutes of deep anal riding and I could feel my orgasm rising and I began to frantically rub my clit as I smoothly continued fucking my brother. "Don't come until I do, my little whore," he groaned, his tone implying he too was close. "Of course, Master," I replied weakly, slowing down my self-pleasuring to not come until told. "On five my fuck slut, come like the little ass slut you are," he demanded. "Oh yes, Master thank you," I whimpered, loving the traditional countdown to pleasure he had initiated during our second earth day fuck-fest at college. "Four my whore," he counted down, the orgasm rising in me begging for release. "Oh fuck, yes, I love being your whore," I declared, my body never feeling as fulfilled with pleasure as when Kevin and I were intimate. Mike, my husband, was a great man and a sweet tender lover, but sometimes I needed to fucked like a two-bit fuck-toy and only Kevin could get me off like that. "Three, my cum bucket," he continued, getting close to finishing his usual Earth Day tri-fecta he had achieved every year since that first fateful day in the Amazon. "Oh yes, Master, fill my ass with your cum," I begged, loving the feeling of his cum sliding inside any of my three fuck holes. "Two, my sister slave," he said, loving to remind me of the incest taboo we continued to commit year after year, even though we were both happily married with children of our own. "Oh yes, Kevin, I love being your full-service sister, ready to obey any order, and eager to please," I admitted, meaning every word of it. "One, I want you to sacrifice one more thing to be allowed to cum, my incest pet," he said, surprising me. "Whaaaaat?" I asked, expecting one to be the simultaneous orgasm we had mastered years ago. "Didn't Kimberly turn eighteen last week?" he asked, holding my shoulders down on his cock and forcing me to stop pleasuring myself, in turn stopped my orgasm that was bubbling so fucking close to the surface. "Y-y-yes," I stammered, already knowing his intent but not able to respond in my current state of mind. "You will bring her with you next year for our Earth Day celebration," he informed me, his tone implying this wasn't a question, but an order. "But, how will I do that?" I asked, the family Earth Day tradition somehow believed by my husband and Kevin's wife, of course they were both unaware of what really occurred during these special weekends. "That is up to you, my slave," he said, "but I will not take no for an answer." "Fuck Kevin, you are one sick fuck," I replied, both turned on and mortified by what he was expecting of me. "Well, it takes one to know one," he quipped back, before adding, "Just agree like you know you eventually will and I will let you come." I didn't want to agree, knowing a mother should protect her daughter, yet I wanted to agree to come and to allow my daughter to experience the rare pleasure that only Kevin had brought me. "Fine," I eventually sighed. "Fine what?" he asked, like he always did. "You can fuck Kimberly," I agreed, the words sounding so ludicrous. "In all three holes," he questioned. "Yes, dammit, you can come in her mouth, her pussy and her ass," I declared, my need to come again overtaking any sort of common sense. "And you will clean my cum from her pussy and ass?" he asked, surprisingly me again. I said teasingly, "You really are one dirty old man." "Answer the question," he ordered, bucking his knees up so his cock went deeper up my ass. "Yes, I will eat Kimberly's pussy with you're cum leaking out," I agreed, "Now fuck my ass, dammit." He let go of my shoulders and without a word I rode his cock like a woman possessed. In seconds, my orgasm was back on the rise and as usual my brother's nasty words brought me over the edge. "That's it sister slut, come like the dirty little whore you are, while imagining me taking your daughter's virgin ass while you licked her ripe young pussy," he whispered. "Can I come?" I asked. When no response came, I repeated, "Can I come, Master." "On five," he announced, and I cursed to myself not sure I could hold on for the short countdown. "In four, my cunt licking sister slut," he said. "I'll eat pussy for you, Master, just let me come," I begged, holding my orgasm from exploding taking every ounce of determination I had. "Three you slutty lesbian whore," he continued, adding, "I can't wait to see you two munching each other's boxes." "Oh yes, I'll make her a good slut, just like her Mommy," I whimpered, the idea of eating my daughter's cunt never once popping into my mind was now suddenly an obsession. "Two, my dirty sex slave." "Oh yes, Master, I will never disobeeeeeey," I replied, the orgasm ready to burst. "Come nooooow, my sluuuuut," he groaned as his cum shot into my well fucked ass. On cue, my orgasm exploded out of me as I screamed, "Oh yes Masssssssster, I love your coooooock so fuuucking muuuuch!" I continued bouncing throughout both our orgasms until we were both spent. Finally I climbed off him and felt his cum slide out of my ass and down my leg. Looking at me, he said disapprovingly, "Look at all that cum you are wasting. Next year we will have someone to make sure every drop of my cum is savoured like it should be." I scooped the cum from my leg and put it in my mouth. "You are serious about Kimberly aren't you?" "Deadly," he said. "And I can tell you are already thinking of eating her cunt aren't you?" I shrugged, "I haven't ate pussy since Vegas," another Earth Day rendezvous and another crazy day. He laughed "That was one crazy night, as was the first time you munched pussy with Mrs. Sheets." "You made me her personal pussy pleaser the rest of grade twelve," I retorted, remembering how mortified I was at first and yet how much I ended loving being used and made into a very well-trained pussy pleaser. "You are welcome," he shrugged. "Thank you Master," I replied, falling to my knees before him and taking his now shrinking cock back in my mouth. "Shit, sister slut, do you ever get enough?" he chuckled. I didn't answer as I began to resurrect his cock. Until Next earth Day...The END!
