That Lucky Dog Bailey lay sprawled upon her bed. Naked, with only a frilly pair of pink panties. Her breasts, small and defined, sagged ever so slightly. Her red nipples poked through her smooth, brown fur, sensitive and aching. Her pillows were strewn about, her head laying flat against her mattress. She stared up at the ceiling, panting heavily, her hot breath seen easily in the cooler air around her. Bailey, a young lynx, only recently celebrated her 8th birthday. Her first heat soon followed, ravaging her body. ‘W-what’s happening to me?’ She said aloud, pushing herself to a seated position, her legs spread apart. Her thighs were soaked, her panties much the same. The white fabric had been stained, revealing her puffy, little pussy. It ached, almost itchy. She moved a paw down to her panties, pressing two fingers against her swollen folds. ‘A-ah!’ Her breath caught, biting her lip as she brought her fingers away. They were soaked, a hot strand of fluid bridging the gap between them. Her heart raced, a pit of worry settling in her stomach. She looked to her doorway, wondering if she should tell her dad. She shook her head, cheeks growing red hot. She slid off her bed, staggering to her feet. Her paw pressed against her hot sex, giving herself some form of temporary relief. She didn’t know why, but it felt good to touch herself. She took deep breaths of the colder air around her, trying desperately to cool down. At the foot of her bed lay her pet German Shepherd. He woke to watch her fumble her steps, his head tilting curiously. He rose, walking towards his precious little owner. Easily twice her size, and twice as protective. He nudged into her, tail wagging. ‘Hey, puppy...’ She gave him a pat between the ears, her eyes closing shut as her little body squirmed uncomfortably. Her thighs dripped steadily, pooling around her feet. The dog eyed her for a moment, nose sniffing through the air. It led him between her legs, his big, wet nose pressing against her puffy folds. ‘O-oh! P-puppy, that’s my private spot...’ He took in her heat ridden scent, his eyes going unfocused. With a whine, he licked gently at her dripping panties, taking what sexual fluids he could. Bailey reared her head, growling and moaning, legs shaking uncontrollably. She practically saw stars as the dog licked eagerly at her needy pussy. Her first little bits of pleasure, emphasized by her incredibly intense heat. ‘N-no! D-don’t lick there...’ She muffled a moan with her paw, her other going to his head. Her heat clouded her mind, filling it with thoughts of pure lust. She couldn’t resist any longer, she needed relief. Her paw pushed her panties down her legs, kicking them to the side. Her flower, smooth and silky. Tight, with just the right amount of pink exposed between those delicate petals. The dog growled approvingly, taking a short sniff of her unprotected sex before taking a long lick up her tiny cleft. The large tongue dragged between her folds, spreading them ever so gently with each lap. His huge, canine cock poked from his furry sheath, her scent driving him into a sexual frenzy. ‘T-that feels... good.. ah!’ She dreaded alerting her dad. She felt dirty for letting the dog lick her kitty, but it felt ooh so right. The dog’s wide tongue pressed deeper into her tiny pussy, licking up against her clit with fierce determination. She squeaked and mewed every time his hot tongue licked her little clit, her legs shaking and shuddering. She was oblivious to his frequent thrusts into the air, his cock spraying pre-cum onto her feet. He nudged into her body, forcing her to the floor. She fell breathlessly, panting hotly. Her body shook with unimaginable pleasure, her pussy squirming and clenching. It dripped freely, begging to be bred. The dog nudged her again, pushing her onto her stomach. Bailey, an innocent, young Lynx, couldn’t fathom why the dog was so eager to move her. She struggled to her hands and knees, panting, trying to catch her breath before trying to stand, but was quickly pushed down into the carpet. The dog had mounted her, his body twice the size and twice the weight. He easily kept her pinned under him. She squeaked! Struggling to escape, but gasped and moaned as his cock pressed rapidly back and forth against her sodden folds. She stopped struggling, her mind lost to her instincts. She parted her legs and pressed her rump willingly against the thrusting dog. She could feel him rub against her pert, little butt, the tip grazing harmlessly over her tight rim. With each thrust, his large balls slapped against her legs and pussy, filling the room with a lewd echo. She moaned, forgetting completely about her father in the next room. She knew little of what was happening, but her heat drove her onward. Blissful mews and squeaks of pleasure. That large, canine cock rubbed gloriously against her tight, little hole. Her paws found a small, heart shaped pillow. She buried her muzzle into the fabric to muffle her arousal. Pleasure built, but the heat would not subside. The itch, that persistent itch! She needed it gone, wanted it gone. Craved relief. The dog would not disappoint. He slammed forward, his cock finally finding her tight, little entrance. It broke past her hymen, his undeveloped knot spreading her folds. She screamed into the pillow, tears flowing down her cheeks as she desperately tried to escape. The dog growled and bit her neck, keeping her in place as he continued his rapid mating. His huge, canine cock grew with each thrust. His knot growing large enough to slap against her soaked lips, splattering her liquids against his balls. Blood flowed around his cock, her virginity belonging to him. He growled and whined, thrusting faster and faster. ‘Omg, omg, omg...’ She braced against the pain, her momentary clarity replaced by her overwhelming heat. She squirmed against him, shaking and shuddering, her paws clenching tightly, her feet pressing firmly against the ground. The dog whined and growled, his fully formed knot slapping against her pussy, begging to be pushed inside. Her tiny hole barely took his full length, her inner walls spread to their limits. She squeezed down on him, her itch slowly fading as his cock pushed deep with each slapping thrust. She moaned and wailed into her pillow, his thrusts becoming fast and erratic. Her body quivered against the dog’s rough onslaught, the unthinkable pleasure overshadowing the persistent pain. She was close, desperately so, a powerful orgasm building just in time for the large dog to shove his bulbous knot into her abused, little flower. Time seemed to stop for young Bailey. Those first strands of hot, dog cum warmed her womb, quickly filling her tiny body. It eased her heat, her body trembling with carnal pleasure. Her stomach bulged ever so slightly, showing off just how much cock had been stuffed into her. Her tight walls clamped down around the canine’s throbbing shaft, milking it for every drop it was willing to give. She came, nearly at the same time she was knotted, her eyes going wide, tongue lolling. Her first orgasm. The pain faded into the back of her mind, her hips tugging on his swollen knot. Her spasming, little folds squirted hot, girl cum all over the invading cock. The hot liquid poured down her trembling legs, her moans echoing through the room as the powerful orgasm rocked her entire body. The big dog panted heavily above Bailey’s head, his hips tugging back and forth. He whined, fumbling with his steps as he twisted around. She squeaked and mewed, her sensitive pussy still clenching in orgasm. He stood, ass to ass, nearly dragging her with him as he tugged on his lodged knot. Bailey could feel the dog’s hot cum inside her. She had been bred, spread wide by that massive canine. She brought a paw to her stomach, feeling the outline of his still throbbing cock. Her fingers slid down to her quivering, little folds, to feel the knot between her petals. She moaned, hotly, gasping and shuddering. Her heat had finally been quenched, but a new wave of pain replaced her sexual instincts and pleasure. Panic began to set in as she tried free herself, squeaking in stinging pain as she tugged fruitlessly on the swollen knot. The dog whined, turning to lick at their joined bodies. Tears began to stream down her face, gasping at each little tug. She looked expectingly towards her door, dreading the moment her father would walk in. Her thoughts swam with negative, post-orgasm feelings. I’m in so much trouble... Dad will ground me forever... Please don’t come in! The little lynx sobbed quietly into her pillow, bracing for a punishment that would never come. She waited ten gruelling minutes before the knot slipped from her spent pussy. Copious amounts of cum spilled from her gaping hole, drenching her thighs and pooling at her knees. She squirmed and mewled, her paw moving to cover her stinging folds. Her paw was pushed away by the dog, his tongue lapping greedily at the mess he made. She groaned, feeling slight relief from the growing pain, but it was short lived. Bailey struggled to her feet, the last of her tears staining her cheeks. Cum flowed freely from her used hole, coating her shaking legs. Her paw moved back down to her leaking sex, pressing soothingly into it, despite the mess soaking her palm. ‘D-did I just have s-sex?’ She gulped nervously, having very little understanding of what it meant. She was breathless, too exhausted to say more. She took her first clumsy steps towards her bed, leaning on it for support. Bailey’s moment of respite was interrupted by the sound of footsteps down the hall. Her ears twitched to the noise, her heart sinking into a pit of despair. A short, gentle knock came upon the door, her eyes widening with fear. ‘Everything okay, sweetie?’ ‘Y-yes, dad!’ Her father jiggled the doorknob, slowly opening the door. She squealed! Racing towards the door, forcing it shut before he could open it any further. ‘D-dad! I’m naked!’ ‘O-oh! Sorry, sweetie! I’ll leave you to it.’ It was too late. The door opened just enough to let the scent of sex and heat waft into the hall. Tom, Bailey’s father, sniffed the incoming scent, his eyes going unfocused. The smell of heat played with his mind, filling it with impure thoughts. His little cub was growing up so fast, the smell of her heat near intoxicating. He sniffed again, this time purposely taking in as much of the left over scent as he could. He exhaled with a long sigh, his pants incredibly tight. ‘That lucky dog...’
