I took a deep breath as I pulled up into the driveway. I was always nervous when it came to showing my girlfriends to my dad. He was always a sexually active man and he always seemed to hit on my mate like she was his instead of mine. I just hoped this time would be different. “You don't need to be so nervous sweetie.” My girlfriend said as she looked over to me, a soft smile on her face. I was surprised she wasn't. She was a lovely mink, not really tall but she was incredibly curvy and had tits that were bigger than her head. She was a dream come true to meet and I loved her every moment we were together. Her smile put me at ease a bit, my stomach telling em otherwise. I had a feeling I knew what would happen before we even got up to the door. Walking up to the door and knocking, we patiently waited for the door to be answered. A loud walking was heard a bit, my ears perking a bit. My dad wasn't usually the one to answer the door. Instead, my mom did. Though I was a bit caught off guard to see the tiger, that was shorter than me by a few inches, was massively pregnant, her belly jutting in front of her like she ate an over inflated beachball, her tits nearly just as big. “Alphonse! What a lovely surprise!” My mother turned to the side and hugged me into her, giving me a nice face full of her breast. Mother was always a bit strong, which only made it a bit more surprising she could move around so easily with her current size. “H-Hey mom... Um, w-when did you get so big?” I nervously stuttered. My girlfriend giggled a bit. I was a bit embarrassed. I didn't expect her to see my mother like this at all; her body only clothed in thigh lingerie. It must've been hard to find anything that could fit her at that size I figured. “Oh this? Your father and I decided to have some more kids! I'm only a month along now!” She giggled as I felt my jaw fall a bit loose. Only a month along?!? She looked like she was well past full-term and should be dropping cubs out of her at any second! Mom smiled as she looked past me to see my girlfriend. “Oh, and you brought a mate as well! It's very nice to meet you dear!” “It's nice to meet you too Ms. O'Riley. My name is Tasha.” My girlfriend said back, brushing her long thick hair out of her face. I blushed a bit more. I was surprised at how fine she was with seeing my mother like this. She practically wasn't wearing anything at all, the lingerie only preventing her breasts from bouncing everywhere. “Well, why don't you two come in and make yourselves at home! Your father is going to love meeting her Alphonse!” Yeah, I thought, he's going to love meeting her. Stepping into the house, I gulped roughly. I knew how my dad was. He was a horn dog, no doubt want to make moves on Tasha. I took off my jacket and hung it up as we walked into the livingroom. The place was just as I remembered it, messy and smelling of sex. My dad was on the couch as usual, watching TV. The reason the place stunk of sex though was he never wore pants. My dad's cock and balls were massive, so big that finding clothing for him to wear was near impossible. He was slouched down, his beanbag balls nestled in between his spread legs. H casually scratched his arm length sheath, the fuzzy mass wiggling a bit. Other than that, he wore a wife-beater on. At least he had some clothing on him to meet my girlfriend. “Look honey! Alphonse and his mate came to meet us today!” My mother casually announced, my father glancing over. The buff tiger always intimidated me. He worked out a lot, only making his powerful musk even stronger. I don't ever remembering him showering in all the years I grew up in the household. He liked his musk and wore it like a badge of honor. He smirked a bit as he looked at me. “Heh, looks like the cub is back again. You bring me a new mate to cuck? You know they only smell my scent on you and not yours. They rightfully belong to me if she did....” He purred a bit, his big tiger sheath wiggling a bit on it's own. He wasn't wrong though. I lived in the household so long that his scent was permanently stained onto my fur. I've tried everything to get rid of it, but it always lingered no matter what I did. That's when Tasha decided to make herself known, my heart sinking a bit. “It's nice to meet you sir! My name is Tasha!” She murred softly as she smelt his scent. It was the same scent she knew from me, her tail swishing a bit happily. My father murred back deeply, his sheath wiggling more, getting a bit fatter. “Murr, you brought me a nice bimbo this time. Damn son, my scent really gets you all the sluts doesn't it? Come on over slut, come meet your new daddy.” He called her over with his paw, Tasha smiling as she swayed right on over. I wanted to sit down as well, but my dad took up most of the couch. I had to be content with sitting on a smaller armchair on the other side of the room. This meant there wasn't much room for Tasha either, but my father lifted her up and had her straddle his massive sheath, her body looking tiny compared to the muscular behemoth he was. The mink murred as she snuggled up into my dad. “Wow Alphonse, you never told me how nice and soft your dad was! He feels even better than you do and smells so much better!” I whimpered a bit. Yeah, I got all the recessive traits. I wasn't strong or hung like my father was at all. In fact, my cock was a pea compared to the size of his cannon. It always made me jealous, but I was soon blushing again as my dad reached up and grabbed one of Tasha's huge tits, groping it roughly. Both murred and moaned, but neither stopped the other from enjoying it. It was always like this when I visited my folks. “So tell me slut, has my cuck son tried to breed you yet?” The mink shook her head and giggled, my dad groping her rougher. “Hehe he's tried, but he's only fired blanks into me. I don't think he's even capable of breeding me! I mean, I barely feel his cock anyways when we have sex, so it doesn't matter too much.” My father chuckled a bit, the conversation only draining my masculinity even further. “Awww that's too bad. He's tried to breed before, but he's never given me any grandchildren. I was hoping you might give me even one, but I guess my cuck son is too weak for that. You seem like you'd be a great breeder though. Go ahead, smell your new daddy....It'll make you feel great...” My dad gave off a deep purr as he gripped her head and shoved Tasha's face into his thick meaty pecs. She moaned back to him, inhaling his scent deeply. I squirmed roughly, covering my tiny erect bulge. I knew what was going to happen next. I watched as Tasha suddenly gripped her belly, her taut stomach starting to swell and get bigger and rounder. Along with it, I could see her pussy throb in her pants and start to swell even bigger. Her womb was reacting to my father's musk, rapidly growing and over producing eggs inside of her. Tasha's tits wiggled as well as they started to swell as well, making her tight shirt even tighter, the fabric of her clothing getting very tight. This went on for a few minutes, until my father finally let her head free from his pecs. Her pussy was massive now, the flesh reaching down to her knees, her belly huge and round, like she was already 9 months pregnant. Her ovaries must have been massive now and swollen with hundreds of eggs. Her tits were massive, even more so than before. They had to be at least twice as big as they were, her nipples erect and jutting out from the fabric. The last change his musk did was only noticeable once she puled away from him. Her once cute face now had a massive pair of lips on it, the thick lips covering most of her face. Dad's musk always turned girls into the most extreme of bimbos, my cock throbbing hard in my pants. “How's that you bimbo slut? You like your new slutty body?” He asked to her, his paws going back to groping her enormous tits. Tasha moaned out deeper and heavier, her body much more sensitive now. “Oh gosh yush dwaddy! It fweels swo fwucking good!” It was a bit hard to understand her now, the mink not used to her new thick bimbo lips. Her answer made my dad grin widely, knowing full well he was claiming and corrupting a new slut for his collection. “Good slut.... But we arent done yet...” He took his sharp claws and freed her body, tearing the seams of her clothing so her slutty body could be freed. “Your ass is still too fucking small. A real bimbo needs an ass bigger than her body...” He unceremoniously lifted her up and made him lay the front of her body on his huge balls, her tits lifting her up a bit. Her pussy throbbed and leaked over my dad's crotch as he positioned her tailhole to his sheath. Sliding her down, he pushed her tiny tailhole to the tip of his sheath. Tasha was moaning out like a slut again as her ass suddenly began to swell up, her tailhole slowly getting thicker and plump. His musk was pouring into her directly from his cock, the effects much more potent as her ass wobbled and swelled rapidly. My dad simply chuckled once he was satisfied, her gargantuan ass, towering over her body. Her massive tailhole was just as impressive, spreading out her hips even wider. He plopped her off his sheath, only a tiny bit of the tip of his masculine cock poking out of it. My girlfriend was barely recognizable at this point. She was once this outgoing small lady with sizable tits, was now a massive slutty bimbo, completely addicted to my father and his entire being. My father was happy with his handy work, looking over the slut with the eyes of looking at his new possession. He stood up and gripped Tasha by the waist, lifting her up like she as a 5 pound weight. With his body, she might as well have been. “You stay right there cuck... Me and my mate are going to spend some personal time together...” I gulped roughly as he walked off into the other room, holding Tasha over his shoulder. She was moaning and groaning out as she disappeared into the hallway with him. He was taking her to the room with my other girlfriends. Tasha was the 8th one this week he took from me, he's claimed many more than that. I was beginning to loose track this happened so much. Before long, I could hear the howls of extreme pleasure from Tasha as my father fucked her like no other man could. He always went into them hard and rough, not caring how much it hurt them. All he cared for was emptying his massive balls and to breed. He always left them a broken mess, bloated beyond belief. I hadn't ever seen my girlfriends after he took them away, he never let me. “Awww don't be like that sweetie. You know your father will take good care of them!” I was so lost in my thoughts, I hadn't even noticed my mother was right in front of me, her ass in my face. She giggled as she sat down in my lap, her soft fat rump squirming against my tiny cock. I whimpered loudly, she was teasing me hard. She had never done this before and I didn't know why. My instincts kicked in though as I gripped her thick thighs, grinding against her roughly. I was panting hard and rough, my tiny cock throbbing hard. I panted and wheezed, my mother murring softly. “That's it dear, give into your need.” She cooed at me. My body couldn't take it. I came as hard as I could, a tiny blotch forming against the fabric of my pants. I moaned out in pleasure. God it felt so good to get one out. My high ended early though as the moaning from the other room stopped abruptly. My mother giggled and I felt a wave of dread and fear flow through my body. “Who. The. Hell. is. Using. My. Wife!” Suddenly a huge hand gripped the doorframe, the wall cracking and splintering up and down the wall. My body went white, or at least it felt like it did. Every inch of my body went numb as I saw two tiny lights come from the dark hall way. I had never seen my father like this at all. “Oh honey, it was terrible!” My mother began and she flung herself to the floor. “He tried to rape me! Your own son! I-I couldn't control him!” My heart sunk even more. What was she doing?! Why was she doing this to me?! I didn't have time to say anything as my huge lumbering wall of muscle father walked up to me. Not only was his scent incredibly strong, but his massive 10 foot cock lingered in front of me, the heat and arousal coming off of it. I was trapped between the couch and his massive tree trunk cock, unable to move. “You've got some nerve cuck...I raised you to be better than this, and THIS IS HOW YOU REPAY ME!?!?” He bellowed out. If my skin could jump off my body, I'm sure it would've as his head came down to mine. Every thick vein in his face and neck was bulging out, a twisted visage of the man I once knew looking at me. I had never experienced such a fear in all of my life. “Punish him dear! Make him pay for what he's done!” Mother looked at me and giggled, knowing full well what she was doing. She knew something I didn't. My dad reached down, his meaty hand gripping my neck and lifting me up. His grip wasn't tight enough to choke me, but I could feel the anger emanating from his skin alone. I didn't need to look at his face to know he was mad. “Do you know what I do to cucks that try to steal my wife? Do you? I break them...I break them and make them work for me. I was letting you slide because you were my son...” He looked at my crotch and saw the small blotch of cum. “But this is inexcusable..” He pulled me back and made me watch his massive cock rapidly shrink down, retreating back into his fat sheath. “I hope you're ready to be a slut, cuck. Cuz you'll be bringing me girls, but as a bimbo slut instead...” I whimpered heavily as my father took me and shoved me deep into his pecs, my nose assaulted by his masculine scent. My mother murred and rubbed herself, watching as my father had his way with me. It took a second but I felt the changes to my body happening fast. My pants were getting tighter, but not because I was increasing in fertility. No, instead my cock and balls were growing. I moaned out as they got heavier, my lower half sagging as I wasn't used to the growing weight. My chest was hot and warm as well, new budding breasts growing in. But they didn't grow in as rapidly as I thought they would. They were smaller plump moobs, still passable as huge breasts, but I was still a man. I didn't grow a vagina, instead my father was making me into a slut of a man. A slut of a man I once was, if I could've even been called one before. Then came the lips. The huge thick flaps of my face grew bigger, engorging with heat and thickness. My moaned became more sexual gargles, the size of them growing huge just like Tasha. It because harder to speak and make sounds, the weight of them something I could never had managed. By the time my father pulled me off of his pecs, I didn't even know who I was anymore. The thick lips made my face more feminine and unrecognizable to anyone that knew me before. My tits were the size of E cups, bigger than most normal sizes, but very small compared to how my father left most women. And last but not least, a three foot cock between my legs with a huge sack that dangled down to my ankles. He tore off my clothing as he did Tasha, letting me fully experience my new body. “Get me the slut gear...I'll finish turning him into my mindless worker...” My father growled at my mother. She giggled and happily got up from the floor, walking off to the hallway to gather the things. My mind was completely cloudy. I was trying to regain my thoughts and composure, but all I could think about was my father and his scent. I wanted him, needed him. My father sat back down onto the couch and dropped me down onto his balls. My ass was facing him as he grabbed my now chubby ankles, my body having become for effeminate due to the changes. Just like with Tasha, he grabbed my ankles and pulled me down onto his sheath. In an instant, I felt and heat unlike any other rush into my tailhole. I moaned out only like a whore could as my ass and tailhole began to change, swelling up big and fast. I could feel my doughy ass grow and wobble, my father groping it like he did to all his pets. My cock throbbed hard and rough against his balls and my father felt it. He growled roughly as he gripped the base of my cock with a strength I had never know before. “You cum slut and I won't even bother keeping you...” I whimpered roughly and whined. My huge cock spasmed, wanting release badly. I had lost track of time as he did so, my ass growing huge and massive behind me along with my tailhole. It was bigger than Tasha's and still growing. It wasn't until my mother came back with the stuff my father requested that he stopped, pulling me from his sheath. The first thing he took from my mother was a large metal cock ring. He fitted it around the base of my cock and tightened it as hard as he could. I yelped out loudly, my huge erecting shivering. “There, now you'll never be able to cum ever again. Your shaft will just spasm endlessly, wishing it could cum, but you'll never get that pleasure ever again.” My father lifted me up and set me down, letting me stand. The next few minutes went by in a blur to me, my sex addled mind not realizing my parents then put me int a very skimpy outfit. Fishnets over my arms and thick thighs, a leather top that ran around my breasts, but had holes to let my erect plump nipples hang out. Last but not least was a thong that held my massive balls, but did nothing to hide my massive length. It didn't matter though, my three foot erection was too big to fit under any clothing anymore. Mom then went to town as she applied makeup to me, turning me into a perfect bimbo for my father. Once they were done, my father slapped my enormous ass, the thick flesh wobbling heavily. “There, now you're a proper slut for me. You'll just go back to doing what you always have been doing: getting more sluts for me to breed. You had your chance to be normal, but I guess you just wanted to be a slut after all. Now then, go get me more sluts, bimbo, and I may reward you...” I moaned out as my body unconsciously waddled out of the house, my enormous ass bouncing with every step. My life became a blur at that point. Everyday was spent trying to hit up more girls to bring them to my father. Part of me missed being normal; to not have everyone gawk at me as I walked down the sidewalk. But you know what? I kinda liked being a sexy hot bimbo. It felt good to be bigger than any or the normal men around me. And even if I could never cum again, I could at least enjoy the fact that my father gave me a dose of his cum every time I brought him a new girl. After all, I was his and I lived to pleasure his needs.
