DOG!" And then the changing. It was painful, but that kind of pain that kind of feels good, like pushing on a sore in your mouth. Shrinking, bones realigning, as I fell to my hands and knees. Then the itching as my brown fur grew out. The pressure of my new tail pushing out from my tailbone. My cock retreating into a neat little sheath. Finally my nose pushed out into a snout and my ears relocated and grew into big floppy ears. I looked up at my wife, now standing on all fours, my head was just past her knees. She was beautiful as ever, 5'6", petite blonde with dazzling green eyes. I couldn't help but pant, I was nervous, but also having trouble focusing on anything. I wanted to please her still, to be obedient. She picked up a small mirror and knelt down to me, the reflection was a medium sized brown mutt. "I'm not done, my sweet little mutt," she reached out to pet me, god that felt good. "Every hour you don't cum, your balls will double in size, as will your load... and you won't be doing the fucking. You now have the unwashable scent of a bitch in heat, but don't worry, human's can't smell it, stinky boy," she giggled a bit. My balls tingled as the incantation took hold. She adjusted her petting to scratch under my chin, I couldn't help but stare obediently. "There will be three things that are the most important in your mind, before everything else... making your owner happy, me. Getting cum from men, and then getting cum from other horny little doggies. All this cum needs to make its way in you, understand?" I felt the synapses in my brain firing, and then stopping, and then firing again. I wasn't gay, but man, some cum would be awesome right now, especially in my ass. She stood and snapped her fingers, a bolt of lightning hitting me in the asshole, forcing a yelp out of me, "don't worry mutt, all the ass fucking will feel good, horny little doggy!" She walked off to grab her phone while I found someplace in the corner to lay and collect my thoughts. What the fuck just happened? I started to shiver, was I always a dog? No! That's my wife and... she's on the phone with the pool boy?" "Hi Garret! ... Yes! Mhm... yes I just wanted to confirm you were still coming this afternoon! ... Mhm... awesome! Hold on! You said you had a pit bull at home right?... Oh! A Cane Corso! Even better! Well listen, my husband is out of town and he just got a dog, do you think you could bring yours for a play date?... awesome! Our little pup is looking forward to it!" I panted as she undressed, I always thought she was beautiful, petite. She started to rub all over her body, little moans escaping her lips. I could feel my dog cock growing, the hot red flesh exposing itself to the cool air. She saw it, "awwh horny little puppy! This body isn't for you anymore!" And with that her body started to put on weight. She moaned as her C cup breasts doubled, tripled, quadrupled in size, hanging down to her belly, which plumped out from it's toned flatness to a pudge that ran all the way down to her now chubby pussy. Her hips widened, past the width of her shoulders, her thighs quickly following, then her ass ballooned out. She kept moaning as she rubbed her perfectly soft, almost fluffy body. I laid there and panted, what the fuck. She smirked at me, "I heard garret say he likes thick girls, and I'm gonna get him to plow my pussy like you never could." She cleaned the house a little bit while I laid in the corner. An hour went by, I could feel my balls swelling, doubling in size, now eggs. It occurred to me I could lick myself. I licked my balls all over, the sweaty, salty taste was amazing. Eventually my cock poked out of its sheath, I licked that too. My mind was lost in the licking, the salty, musky tastes. I felt like I was getting close to cumming, but it wouldn't come. My wife entered the room, still in the nude. I stopped licking, swallowing that last mouth full of testicle flavored saliva. "Dirty dog," she giggled, " I told you, you can't cum that way, someone's gotta fuck your ass, silly bitch boy," she walked away, back into our bathroom, I followed. "Don't you think mommy would look good with some tan lines?" She said. With a snap of her fingers, most of her skin darkened a few shades except for an area that would only be covered by a micro bikini. "Good, I think Garret will like that." She smirked and headed back into the bedroom, I watched her pull out one of her bikinis. Now obviously too small for her new ultra-curvy body. She squeezed herself into it, the string digging into her plump hips and tits, the thong back completely disappearing in her gargantuan ass, and the tan lines perfectly covered. She plopped down on the bed and scrolled her phone, while I took my spot in the corner. Another hour went by, my balls swelling again, to the size of baseballs. I desperately licked my dog cock, fighting for an orgasm that wouldn't come. My balls ached horribly, my hole winked begging to be filled. I don't want it in my ass I thought, but fuck it would probably feel good. The door bell rang, I got up, my cock quickly retreating, my balls swollen enough to knock against my doggy knees. My wife sprang out of bed, her whole body jiggling as she trotted to the door. "Hiiii Garret! How are you??? Oh this must be your pup! Such a nice boy! And so big!" She shot me a look from around the door. "Uh hi Mrs. P I'm doing good, uh how about uh, you?" Garret was a tall lanky kid. Very tan from working out in the sun. Shaggy dirty blonde hair and always clean shaven. He was a shy surfer bro type. "So good Garret!" She gripped his arm as he walked through the door, "wow cleaning all those pools built up some real guns huh?" "Haha, uh yeah Mrs. P it sure has." Garret tried to pull the dog in the house, but he wouldn't come, "cmon killer! Come in!" In stepped the biggest dog I'd ever seen. Jet black fur, a huge head, and bulging with muscle. "Don't worry, he's really sweet, my brother named him killer" My wife knelt to pet him, squatting his head was level with hers. She rubbed his head all over and gave him a kiss on the nose, "such a good boy, killer!" I couldn't help but eye his crotch, his balls were naturally bigger than mine, and his sheath was longer and fatter than my dog cock was hard. My wife stood as Killer looked at me, panting, I knew he could smell my bitch in heat scent. "Well, why don't we leave these two to play and you and I will go out to the pool?" "Uh, sounds good Mrs. P" Garret said, grabbing his bag. My wife rubbed his back, "please call me Patty, Gare-Bear" Garret chuckled nervously as he stepped out the glass door, my wife on his heels. I rushed to the glass door to watch the two. I couldn't hear what they were saying. She crossed her arms under her massive rack as she spoke, I could tell Garret was ogling. She explained what she wanted done and then laid out on her stomach, ass toward the pool. Garrett stood stunned, mouth open at her huge ass, before getting started. Just as he was about to dip his net in the pool she called him over. A short exchange and Garrett grabbed some sun screen as she undid the back of her top. I felt Killer's looming presence behind me. A cold nose nudging my winking asshole as Garrett started to massage lotion into my wife's pillowy ass. God that tongue feels good. My head was swimming in the feeling. Killer's huge rough tongue lapping at my doggy pussy. I forgot all about my wife, and the young stud copping a feel. My dick grew out of it's sheath, throbbing in tune with my ass. Killer just kept licking and licking, I let my tongue hang out and drool flow into a puddle on the floor. My wife turned over, leaving her top underneath her. Garrett rubbed lotion into her tits as she reached for his tented shorts. She winked at me as she pulled Garrett's exposed shaft to her face. I could tell she was blowing him as Killer hopped on my back. I couldn't help but hold my tail high as his huge dick stabbed painfully at the back of my swollen sack. My mind blanked, I couldn't describe the pleasure as Killer's massive cock speared into my virgin depths. It felt like his girth was going to split me in two. His length probing my stomach as he began to fuck me harder than I thought I could take. Killer sunk his teeth into my scruff, hard enough to draw a little blood. He growled, fucking me rough. All the sudden my face was against the glass, Garrett pulling my wife's thong over her expansive thighs, and her smiling at me as I'm getting my butt absolutely fucked. I could feel my orgasm growing like never before. Killer's monster dog dick battering my prostate and bulging my belly. My wife pinned her legs over her head by hooking her elbows behind her knees. She pulled Garrett in, his cock sinking into her soaked cunt in one motion. I could see her moaning, grabbing Garrett's hips as he roughly mauled her tits. She's right, I never fucked her that hard. My concentration broke, Killer was growling loud, his thrust stopped, my brain turned to mush as he forced his softball sized knot into me. My hole locked around his shaft, seizing as my orgasm kicked off. I saw stars, my head hanging. My little dick spewed and spewed, hitting my chest, neck and chin, coating them in ounces of white dog spunk. Killer took shallow thrusts, his cock injecting my guts with white hot cum. I felt like I would burst, my belly growing. It pushed my cock down, my balls continued to empty into a growing puddle on the floor. My vision returned as Killer swung his leg over, his monster cock spinning in my guts. I could still feel him cumming, my belly still growing, his knot locking it in. I could tell Garrett was about to cum, he tried to pull out, but my wife wrapped her legs around like lightning, pulling his face into her tits in the same motion. She smirked at me as Garrett took shallow thrusts, emptying his balls into her pussy. My wife unlocked her legs and gave Garret a kiss, letting him pull out, a river of cum following before she clenched it in. She let him up, he walked around the side where she could lick his cock clean. He turned and look at his pooch and I, Killer still emptying his nuts into my bulged stomach, and I still drooling in pleasure. Garret's mouth hung open, cock slowly drooping to the ground. My wife was up in an instant, standing behind him, her huge tits pressed against his back. She whispered in his ear, his face remained blank until his head sagged back and his eyes closed. She shot a smirk to me over his shoulder. Reaching around she grabbed his cock, slowly jerking it. It got harder, growing, bigger, bigger, almost a foot long, and thick as a soda can. His sack hung lower, the weight of his now softball sized nuts hanging heavy. Garret's head snapped forward, my wife smugly waved to me as he pulled the glass door open, immediately squatting down and tapping his heavy cock on my head. "Open up bitch boy!" He cued. I had no choice, I hesitantly opened my mouth, hanging my tongue out, which he eagerly laid his heavy cock across. My brain felt good having his cock in my mouth, even when he slowly pushed it deeper. I gagged but he didn't care, every gag and squeeze forced a moan from his lips. I wanted his cum, I needed it. I lapped at the underside of his immense shaft as he probed deeper and deeper, my throat opening for him. Eventually my tongue met his balls, he was hilted deep in my throat. His huge cock had to be almost touching killer's they were both so deep in my guts. Garret gripped my ears. Suddenly pulling out. He pulled my ears, tugging me forward on Killer's locked knot, and simultaneously pushed his hips forward, mashing my nose against his hips. I could feel my throat bulging as he fucked me, if my stomach wasn't so distended from Killer's load of puppy batter, I'm sure it would be bulging too. My mind was mush, Garrett's new tumescent cock plunging deep into my esophagus, Killer's monster knot stretching my ass, locking his load in. Garret's strokes got sloppy, his grunts turned to moans, he mashed his pelvis against my nose, his fat nuts seizing against my chest as he direct injected his load into my belly. My stomach grew and grew, I could feel the wetness of my own cum puddle as my belly eventually met with the floor. He held me there, dumping his load, and then he let go of my ears and let his softening cock flop out. "Good girl..." Garret murmured, patting my head. He stumbled to the couch and flopped down. My wife was sat on the porch table, her feminine juices splattered all over the concrete after a messy orgasm. Before I could form another thought, my brain once again went blank. Killer's knot popped out my ass, a geyser of cum following his beastly cock. I clenched quickly my gaping hole doing it's best to hold the intense volume of beast cum inside. I fell onto my side, too tired to move the immense weight of my gravid, cumfilled stomach. The sliding door opened, my ultra curvy wife, no master, stepping through. She knelt and rubbed my cummy tummy, "that's momma's good boy..." she cued quietly. She headed toward the bedroom, and I heard the bed squeak as she laid down. I slowly drifted off to sleep, my balls empty and my guts full. ---------------------------------------------- Thank you all for reading! Feel free to shoot me a message! Bigcosk@gmail.com
