I got home from school that day and I was horny. Sixteen, pushing seventeen, I was already sexually active, having had sex with some of the boys at school and with my pet German Sheppard. I let him mount me almost every night. This day, my brother was going to be late coming home and my mom, as usual, was at work until midnight. Since I was going to be home alone for awhile, I called my dog to my room as soon as I walked in the door. I stripped naked and got on the bed on my hands and knees and called him as I slapped my palm on my exposed ass cheek. He jumped up, knowing what to do and stuck his snout into my crack and started licking my ass and pussy. He mounted me and, as I guided his cock to my pussy, penetrated me easily. His knot grew and we became locked together. Just as he was starting to cum inside me, I heard a noise behind me. I twisted my head around, even as I began to feel the amazing heat of dog cum filling my pussy, and saw my brother standing in my open doorway! My dog and I were knotted by his bulge and my orgasmic squeeze on his spurting cock. I couldn't do anything except let him finish cumming inside me. I was in a state of shock at being caught but I was also in the midst having a mind blowing orgasm. No matter what, I wasn't going to stop and lose out on enjoying the exquisite feel of my dog's cum filling my pussy. I loved the feel of it squirting into me as much as I loved the full feeling of his knot. My seventeen and a half year old brother stood there, leaning against the doorway, a smirk on his handsome face. I could see the huge bulge of his hard dick straining the front of his jeans. Still knotted to my dog, I watched as Josh walked into the room, climbed up on my bed and knelt in front of me. He undid his jeans, slid his hand in and withdrew it, along with his cock. "Well, sis, I see you like to fuck. If you can fuck the dog, you can suck my cock, too!" He declared. I stared up at him in shock and confusion. I could see the smirk and anticipation on his face and lust in his bright blue eyes. Like me, he has blond hair but his has a tinge of brown and is neatly trimmed. The motion of his hand caught the corner of my eye and I looked down. I found myself staring at his cock. I felt excitement and desire filling me even as my dog finished shooting cum into my pussy. Josh's cock was the most beautiful thing I'd ever seen! I'd already played with many cocks at school but his was the most exquisite I'd ever seen. Maybe it was because it was my brother's, which I always envisioned was what was sliding into my pussy when guys had fucked me. It had a thick shaft and a bulbous head with a slit in the center. The ring at the base of the head was beautiful in my eyes. I noticed, as I licked my lips in anticipation that some fluid was beginning to leak from the slit. I had to taste it and see if it was as delicious as all the others I'd sucked. I leaned toward him, already lusting to feel his beautiful dick in my mouth. There was just something about it that made me yearn to feel it in me. When he had it next to my lips, I suddenly stuck out my tongue and licked up his wet stuff. I discovered that he tasted almost the same as my pussy! I loved the taste! I ran my tongue around in my mouth, savoring the flavor and feel of his pre-cum. I saw more leaking out of his slit so I quickly licked it up as well. I looked up at him and smiled. "Josh that tastes great! Can you make more for me?" I questioned him. Josh smiled down at me and ran his fingers through my hair as I looked up at him expectantly. He took his shaft in his other hand and pushed forward. Eagerly, I let him push the tip of his cock between my parting lips. As the head slid past them, I ran my tongue all over it. I'd never felt anything in my mouth that was so perfect! He was stretching my jaws but I didn't notice. The feel of his spongy head on my tongue was exquisite. The fluid dripping from him tasted better than anything I'd ever consumed. As he continued to push forward, his shaft was hot and pulsing, just like the head. The ridge scraped along my tongue and the roof of my mouth. It just felt so perfect! As he pushed deep into my throat, I felt a momentary gagging. I was totally filled with lust and intended to have all of him in my mouth! It felt and tasted so good, I forced my throat to relax and he slid in easily. I'd never felt anything so wonderful. I'd finally deep throated a hard cock! As I began to wrap my tongue around his shaft and explore him, I felt my dog pull his spent cock out of my pussy. I could feel his doggie cum starting to run out of my pussy and down my legs. I grunted around Josh's cock and clenched my pussy closed to make sure it stayed inside my cunt. This being the first time I'd ever deep throated a cock; I didn't know what to do. I just knelt there working my mouth, tongue and lips around it. I was enjoying the feel of his fluid dripping down my throat. It felt so slick and hot I wanted him to just stay in my mouth like that forever. Josh didn't seem to know what to do. I found out later that it was the first time he'd put his cock into a woman. He was my first deep throat fuck and I was his first sexual partner. Natural instinct soon took over and Josh began sliding his cock in and out of the sheath of my mouth. I just held my body still, clutching him loosely with my tongue and lips and keeping my teeth away from him. The sensations he was creating by his motions were pleasurable. I soon felt my nipples getting tight as they did when my dog fucked me. His motion continued and soon he was pushing his entire cock into my mouth. When he was buried in me, the tip was tickling the back of my throat and almost making me want to gag. I just relaxed my throat as I often did to swallow something I didn't like and let him slip in and out. The fluid dripping out of the slit in his tip ran freely down my throat each time he pushed in deep. I found that I loved the feel of it! I was quite happy to stay there with his cock in my mouth as long as he wanted! Of course, this being Josh's first time, his skill wasn't up to its full potential yet and he didn't know how to make himself last. It didn't take long before he was breathing hard and thrusting rapidly into me. I loved kneeling there, holding steady as he fucked my face. The feel of his cock sliding back and forth in my mouth, touching every nerve ending, leaving me coated with the fluid pouring profusely out of his tip was amazing and arousing. Suddenly, he pushed in hard and deep, slapping my face with his belly. I felt a huge flood of his fluid squirting out of his tip and down my throat. My brother was cumming in my throat! I was startled at first, never having a boy cum that deeply in my mouth and began swallowing eagerly. Josh had his head thrown back, lost in his own pleasurable sensations. For me, it felt like I was in heaven so I just held still and let him use me. His hot and silky cum felt wonderful in my throat, coating me from tonsils to gullet. I pulled my face back from his belly and his last spurt landed in my mouth on my tongue. I let the silky and sticky substance coat my lips and gums, swirling it around with my tongue. It tasted salty but with other pleasurable flavors. As I swallowed all of it, I decided I liked what his taste and I was going to make him do it with me again! Spent and softening, I let him slip his cock out of my mouth. He was breathing hard and his face was flushed. As he slowly returned to normal I continued to kneel there staring up at him, savoring the remaining taste of his cum in my mouth and the feel of my dog's in my pussy and on my thighs. "Myra, why were you fucking the dog?" he asked when he finally had his breath. "About three months ago I was on my bed after taking a shower. I was horny and got on my hands and knees, like today, stroking my clit and fingering my pussy. He jumped up on the bed and stuck his nose into my ass crack. It shocked me at first but felt so good! I let him have his way, licking my pussy and ass. Then he suddenly jumped up on me and began to hump against me. His cock felt so different than the boys I had just fucked and it was turning me on. I was almost at my peak so I grabbed him and put him into me. Josh, it was the most amazing feeling! When his knot grew and he pushed it into me, I clamped down on it and we were locked together. It was so sensational; I've been letting him mount me just about every night since!" I told him about using my fingers and my hairbrush before finally letting some boys at school fuck me after my 16th birthday. He asked for details and, of course, how many and who. I felt quite open and relaxed with him as I told him everything. He was surprised that I'd had sex with so many of the guys he knew, just about every boy at our school. As we were talking, I'd been holding his cock in my hand and stroking it. I looked down and was amazed at how it had changed back into the form it had when he put it into my mouth. "Josh, would you put your cock into my pussy? Would you fuck your little sister?" I asked him. He stared deeply into my eyes, seeing my pleading need in them. My face was also etched with my lust for him to mate with me. I could see that my fantasy's were about to come true and I was going to be my brother's lover. I could also see some doubt and hesitation on his face. "Josh," I asked him softly, "Please fuck me, I've always wanted your cock inside me. I'm all wet and sloppy with dog cum and I want to see how your cock feels inside me that way." "Well, I've never done it to anyone but I'd like to. I dream of putting it into a girl a lot at night and, most of the time, you’re the girl." He revealed to me "Oh Josh, yes! Please put it in me. It's you I see whenever a boy fucks me! I want to feel you really fucking me!" I replied excitedly. Mom, seldom home, never talked to either of us about sex so we were exploring and discovering on our own. We didn't realize it wasn't a good thing for a brother and sister to have sex and, naked and aroused, we didn't care. All we knew was that it was something we both wanted and needed. We loved each other and felt that joining our bodies into one was the right thing to do. He got behind me and slid his cock right into me. I could feel it sloshing around in the doggie cum filling me. He was shorter than the dog but he felt perfect inside me. I loved the sensations he was giving to me. With each of his thrusts, I could feel the doggie cum moving inside me and being pulled out with him. Soon, it was running in streams down my inner thighs and soaking into the sheet from my knees. He fucked me for about a minute and then he shot his cum into me. It felt really good, but I didn't cum. Josh then surprised me by holding his cock inside me. He reached around me and began to play with my tits. His gentle stroking and caressing felt really good! When he slid his hand down my belly and into the top of my slit, I gasped when he hit my clit for the first time. He kept using his fingers on it and asking me how it felt. All I could do is gasp, and coo as my hips rocked against him. I felt his cock getting bigger and harder inside me again. I began to ride him instead of waiting for him to fuck me. I told him to keep playing with my clit and my nipple. Soon, I felt the tingling I'd so often felt when my dog was knotted in me. I let it grow and expand until I suddenly felt my orgasm ripping through me! I let a scream of pleasure escape my mouth as my pussy clamped down on Josh's cock and rippled along his length. I heard him gasp and then felt his hot cum squirting into me again! What we were doing felt so good, we just continued all night. By the time mom came home, he'd fucked me five more times and I'd cum on him three times. Josh was exhausted as he dragged his naked body out of my bed and into his own room. From then on, Josh would come into my room every day after school and watch me fuck the dog. He seemed to really enjoy watching me being mounted, penetrated and knotted. I learned to become quite vocal, always telling him what was happening inside me and how it was making me feel. I began to stare deeply into his eyes as the dog brought me to orgasm, as he usually did several times each time he mounted me. When the dog was done, Josh would come over from his seat and then fuck me. He never took his cock out of my pussy until he'd cum in me at least three times. We'd rest for a bit and then he'd mount me again. After awhile, we learned about different positions and we started experimenting. By the time my poor old dog died, Josh had mounted me missionary, legs over his shoulders, sitting on his lap, front and back, me on top facing him and on top with my back to him. We also learned how much I loved anal sex when he put it in me there accidentally one day after the dog had fucked me. I was so wet, he slid into me easily. I know now its because of the rather strong control I have over my muscles that I was able to accommodate him easily. After that, we would fuck as much as we could until mom came home. I often went to sleep with dog and boy cum in my pussy and Josh's in my ass and mouth. Eventually, my dog died and I never got another one. My brother continued to fuck me every day possible, even, at times, during my periods. We used to do it anywhere and anytime we could! By the time I turned eighteen, I was an experienced slut, having fucked almost one hundred different guys by that time and about fifteen girls, including my brother's first girlfriend. He'd become quite an accomplished lover himself. When we both started dating we still fucked together. Eventually, we would fuck and share stories about our other partners and dates as we were joined. He was the first one I told about wanting to be gang banged. He knew some of the guys on the football team and just happened to tell that to them. He got me invited to the varsity football party after the last game. I went there wearing a halter top, no bra, short skirt, no panties. I wasn't there more than a few minutes before the quarterback came over to me and started talking to me. He brushed my breasts and told me they looked great. He then asked if he could see them and I said sure, where do you want to go? He said to show him them right there. A lot of the other guys were watching me as well. I shrugged, grabbed the bottom of my halter and pulled it up over my head and sat there naked to the waist. They liked what they saw and asked to see my pussy. I stood up and pulled my skirt down, stepped out of it and sat back down, spreading my legs for them. The quarterback then said he'd heard I wanted to be gangbanged. I told him yes, I did. He picked me up, carried me into the dining room of the place and set my naked ass on the edge. He told me to lean back and I did, resting on my elbows. He then took out his cock and slid it right into my sopping wet pussy. God it felt good! He fucked me until he came and, as soon as he took it out, one of the black wide receives took his place and slid my first black cock into my pussy. I couldn’t' stop staring at my pussy as he slid in and out of me! I came just watching him fuck me! I hated it when he came in me and then pulled it out. Well, the rest of the team, including the black running back and the other black wide receiver all fucked me. I was flat out on the table for most of it. When they were all done, I laid there and let whoever came over fuck me. I had 45 different guys fuck me that night, most of them twice. The three black guys did me about four times each because I kept begging them to put their chocolate cum into me. I went home sore, cum running down my legs, tired and happy. My brother crawled into bed with me and made me tell him all about it but he didn't fuck me. I was sore for a few days so we didn't do anything. I started to get sores on my pussy lips and showed them to him. He told me I had to go to the doctor because I had the clap. Well, I went and I had syphilis. The quarterback had given it to me on his first fuck. Just about all the guys on the team had it from fucking me after him. It was a scandal when I had to tell the names of all the boys I'd been with during the time I contracted it. Mom knew from that point on just what a slut I'd become. She wasn't happy about it and tried to limit me but I always found ways to have sex with guys and girls. She never did realize that one of my most frequent lovers was Josh. After I left home for college, I continued my ways and cut quite a sexual swath through the schools population. But, from my pulling that train I learned to make sure that any partner I share myself with is clean. That has worked well for me since, in spite of an additional four hundred or more lovers since then, I've never contracted anything. With proper care, a cum slut can capture in her body all the cum she craves and still remain disease free! And now, I have to make myself pretty. My brother is coming by today for the first time in two years and we both intend to see how much of him he can leave inside me!
