(The following is a work of fiction. The character of Kathran is copyright her player, this story being written at her request. This story contains some masturbation, vaginal sex, water sport, semi-incest, and impregnation.)

Kathran woke up, panting slightly. She pushed the sheets aside, sitting up. Whatever she had been dreaming about was already becoming hard to remember. Something about her and her dad. Whatever it was, it was intensely pleasurable. Her panties were wet, showing the outline of her crotch and private part, almost being completely visible. Her shirt was also wet, two big wet spots from her nipples outward. The nipples were still erect, poking through the fabric of her shirt.

The brown furred feline pulled her shirt off, letting it go and looking at her breasts. It was strange. She had started to develop early for some reason. Now here she was at eleven, standing four foot four with breasts, were she full grown they would be DD or maybe a low EE. What more, they were full of milk, leaking out on occasion.

She shifted and shuddered slightly. Her stomach felt funny to her. It seemed to be sensitive and tingle in a pleasurable. Kathran laid back on her back, reaching down to pull her panties off. A moan escaped her lips as the wet cotton rubbed against her swollen girl part before pulling off her and sliding down her legs. She then shivered as the air touched her wet crotch.

One paw reached down, stroking through the soft brown fur and over the wet lips. Another moaned escaped her and she shivered in pleasure. Her stomach clenched some as though wanting more. She felt hot down there, and more wet stuff seemed to leak out of her. She finally climbed out of her bed and got up, going to check on her dad.

He was not her actual dad, biologically. He was not even the same species. She was a cat and he was a dog after all. Kathran had been found by him a few years ago and he took her in, adopting the feline as his own daughter. Since then he had helped her get clothing, go to school, and even comforted her when she was crying from being picked on for her chest, explaining how some of the other girls were jealous.

She stopped at his door, looking in curiously. Her big blue eyes adjust quickly, catching sight of the empty bed. She looked around, then stepped inside his room. Her nose twitched some, catching the smell of something. She was not sure what it was, but it made the warmth in her lower stomach grow stronger. Her tail lashed some as her sex started to drip, leaving a couple spots on the carpet.

Kathran climbed on the bed, purring as she sniffed at it, catching more of the scent. She pressed herself against the sheets and started rubbing, trying to get more of whatever it was she was liking as well as getting it on her somehow, and leaving her own scent to mix with it.

The small feline got up and slid off the bed to the floor. She padded back through the house, going to the kitchen. She smiled as she got herself a bowl of cereal, then went to the living room The feline turned the TV on then laid down on her bare stomach to eat while the cartoons were on.

Her ears shifted as she heard the door open, then shut. She pushed up off the floor, running through the house. Her tail flicked excitedly as she went down the hall toward the front door. When her father came into range she squealed and jump, pouncing at her father and hugging at him excitedly.

The canine crouched down, catching the seventy pound feline projectile. He grunted as he picked her up, hugging his daughter back. He rubbed his cheek against her, murring as he held her close to him.

Kathran pressed her naked body against him more, her nose pressing into his fur and sniffing. The masculine smell excited her more, causing more wetness. Her tail flickered in excitement as she pressed against her father, small bits of milk leaking from her nipples onto his shirt.

The young feline's father stopped a moment, shifting some. He leans closer, sniffing at his daughter curiously, ears pulling back some. The scent had changed some. He felt his sheath start to swell as the shaft inside started to react, causing him to get aroused.

"What have you been upto kitten?" the canine asked the young feline. He shifted more, feeling the swell starting to become uncomfortable in his jeans.

"Just watching cartoons and eating breakfast," she purred out as she nuzzled into him, "Mrrr.... You smell really good daddy. I like it a lot." She pushed against him more, chest vibrating with her purrs. One of her feet moved up, pressing against him, and the toes slipping into the waist of the jeans. She wrapped her arms around his neck more, pressing her head against him.

"Uh... Kat?" He asked with slight nervousness, "Do you remember how I explained that you're getting breasts was a part of you growing up and talked to you about reproduction some?" He set his daughter down, then crouched to be at the same height as her.

"Yes," Kathran replied with a small nod, "When a girl grows up more she starts going into heat, which makes her more sensitive in some ways and able to have cubs. Why?" She tilted her head to one side, mirroring the movement she's seen him do whenever her was curious about something.

"Well I also told you it made boys act funny," the canine continued, "Anyway, it seems that you have come into your first heat Kathran. So you should probably put some clothes on and play in your room. You definitely shouldn't go outside to play for a while, until your heat's passed."

"Is daddy having a hard time being a good boy?" she giggled out. The feline then lunged at her dad again, this time catching him off balance in the crouch and knocking him on his back. She pressed her smaller body against his, rubbing furry body along him with a loud purring.

"Kat, what are you doing?" he growled out some. One of his paws reached down to her back, getting ready to pull the four foot plus kitten up off him. Something caused him to stop though, running his paw along her back and up tail.

"I love you daddy," she moaned out, "I want to show you how much you mean for me and thank you for adopting me." She pushed her head under his, rubbing at the underside of his jaw and nipping at him with a purr. One of her paws slid down, rubbing at her stomach before slipping into his jeans.

"Kathran no!" the father ordered before speaking, "Even if you weren't my daughter young lady, you're still too young for such a thing." He reached down, pulling the paw out of his pants. Without thinking or realizing, his other paw grabbed at her side, paw pressing at the side of her breast with the thumbnail pressing against the nipple.

"Too young?" the feline pouted out, "Dad, I am eleven years old, you said so yourself I'm in heat, and I've already have tits showing that I'm a big girl and old enough." She then stuck her tongue out at her dad, blowing at him audibly.

"You're not supposed to use language like that Kathran," the older male stated. He pulled back a paw and swung, swatting the young feline on the rump with an audible slap. Normally this would have stung slightly and been enough to correct her behavior. This time however, it sent a thrill of pleasure through the feline, arousing her further.

"Again daddy again," she moaned out, "I've been a naughty girl and need my daddy to punish me." Her legs spread apart. She pushed herself down some, grinding her sex against his jean covered crotch. She reached to his shirt starting to pull it up off him.

Something inside him started to give in more. He let his daughter take his shirt off. He then reached down. One paw moved to cup the young feline's crotch, pressing his paw pad against her warm, wet, swollen vaginal lips. He rubbed at her as he moved and slipped out from under her. The male stood up, undoing his jeans to take them off and step out of them.

Kathran looked at the sight of the nude male, moaning at the sight of the thick hard shaft, swollen at the base and leaking pre. She slid one paw down, stroking at her crotch at the sight of her father's shaft, imagining how it would feel inside her body.

The male moved around behind the female, moving down behind her and lifting her up some. He carried the kitten into his bedroom, setting her on the bed. He kept her up some, pulling her back toward him as he moved forward. The topside of the shaft pressed against her sensitive nether lips, the tip of his shaft poking out past her slightly with his hips pressing against her rump. One paw wrapped around her waist, holding her back against him. The other reached down rubbing at her nether lips and teasing the feline clit.

The young feline moaned out, arching her back to press against the canine chest. Her breasts pushed out as she rocked her butt against his hips, pressing her sex against the hard shaft under her grinding against it. Her body shuddered as the large finger pressed at the sensitive little button.

The hips started to rock, stroking the shaft along the young opening. The length pulled back then pushed forward, spreading the lips slightly before pushing out in front of her. The finger continued to shift, teasing at and stroking the sensitive nub

With the heat, arousal and all the excitement from earlier, the teasing did not need to last long. Kathran's head pulled back as an orgasm racked through her body. Her muscles tensed as she twitched slightly. The walls of her inner depths clenched and squeezed at nothing. The female cum flowed onto the shaft between her legs.

As the climax subsided, something else escaped the young female. The watery fluid also flowed from her, pouring onto her father's shaft as well. The feline opened her eyes, looking down in shock as she felt her bladder unloading the contents.

"I...I'm sorry daddy," she whimpered in embarrassment, "I didn't mean to. I just-" Her words were cut off with a moan as the canine jaws took a hold of the young feline scruff. She pushed back, pressing into her father more. She let herself be pushed forward onto all fours, bracing herself some for what she hoped was to come next.

The canine pulled, back, stroking his length along her as he lined up with her. The arm's wrapped around her, holding the young feline as his paws pressed into her breasts. They massaged some, causing milk to leak from them. The male then pulled his daughter back as he thrusts forward, the tip spreading her open. He speared into her depths, tearing the young female's virginity as he sank in. The shaft pushed in until the knot pressed against her. He pushed more, sinking the knot, coated with female cum and urine, into her depths with an audible pop.

Kathran moaned, almost screaming, in pleasure and pain as she was penetrated, her virginity taken, and almost instantly tied with. Her body clenched down more as the knot sent her off into another orgasm.. The milk poured from her nipples into the pawpads as her canal gripped and squeezed the shaft. The feline pushed up and back, pressing herself and grinding against her father's chest and hips. Her body vibrated some with her purring.

The father growled out in pleasure, his own chest rumbling some against her purring back. He holds her tighter. The canine hips pull back, tugging against her some. He then gives a fast hard thrust, stroking the shaft and knot along the depths as he sank in as deep as he can. The canine rapidly pulled back then thrust forward, speeding up as he pumped back and forth. He hold the feline tightly, working to get himself to orgasm as rapidly as he could. From all the teasing as it was, he was not going to last long.

The young daughter continued to rock and shift, stroking against her father as she pumped back against him. Her walls continued to squeeze and pump, trying to milk the shaft of all the seed. Her body was tense with pleasure.

"Come on Daddy," Kathran moaned out, "cum in me. Fill me with your puppies." She wrapped her tail against his side as he pumped, feeling the tension in his body. The strokes of the knot and shaft kept her at a height of pleasure.

The male pulled back once more then thrusts forward, sinking into her as deep as he could get. The knot inflated, growing as large as it could to lock him in place and seal off her canal. He let the scruff go, head tilting back as he snarled out in pleasure. The shaft swelled and twitched, then unleashed the thick ropes of warm canine cum deep into the wanting fertile depths of the young feline.

The young cat shuddered and shook, her body in so much pleasure and stretched by her father, she felt she would explode. Her muscles clamped down as hard as they could, collecting every drop of the canine seed and pulling it up into her womb.

Kathran collapsed onto the bed in exhaustion, panting heavily from exhaustion and to cool her body down. Her body went limp as all the energy drained out of her and her eyelids started to feel heavy. The young brown feline decided to close them, just for a moment. It had been wonderfully fun playing with her daddy like this. Maybe they could do it again. And maybe they should, again and again, everyday until her heat ended, just to be absolutely sure. She slowly slipped off to sleep, unaware that there was no need to keep trying. That her father had done what she had wanted.
