Fate struck Jon hard, when his wife passed away, while giving life to their first and only child. Jon was a tall and strong snow leopard in his 30s, having had a lot of luck with the ladies when he was younger, but his wife was the love of his life. Unlike his white fur, his daughters had a regular orange fur coat, which she got from her mother. Being a single father was very tough on Jon, as he had to cope both with the extra workload and the passing of his lover. And it was only a couple days later, when another big problem of fatherhood arose. 
After a stressful day, taking care of his daughter, he found himself hurriedly searching his house for even a scrap of formula.  He had forgotten to buy any for the weekend, with all the stress of taking care of everything himself. While he was scouring the house, his baby daughter was crying, as her belly ached for food. He was holding her in his arms trying to calm her down, as he tried his best to find her any food, but unfortunately there was nothing left.
When he desperately tried to think of something, an idea began creeping up in the back of his head. It was something forbidden he only had fantasies about during puberty, but now it started to become plausible. Back then he felt ashamed to have such desires and he would have never thought he might act upon them. But he had to help his child anyway he could, so sat down on his couch and placed his daughter next to him. Before going through with it he took a deep breath to calm himself, his body getting too excited.


Inside his pants a bulge began to form, as his cock began responding to his perverted thoughts. Quickly getting so hard, it was hurting and trying to break through its prison. When Jon slowly took off his pants, his fat cock shot out from his pants, fully erect and throbbing, flinging pre cum across the room. He was grabbing hold of his pulsing cock, as if to try to calm it down, doubting if he really was doing it for his daughter.
While his cock was throbbing aggressively and leaking precum all over his handa, the room began to fill, with its intoxicating musk. The toddler was paying close attention to what her daddy was doing and when her nose picked up the irresistible scent of cum and musk, she began crawling towards her daddy's big throbbing cock. 
He was taken by surprise, when his infant daughter suddenly wrapped her tiny arms around his shaft, holding onto it tightly. Feeling a woman's touch even so young, was making his member shoot pre in the air, which landed right on her face. After a moment of shock the funny feeling was making her giggle. The smell of her daddy's cream was so alluring she began to try and lick it up from her face. Unknowingly her actions were making her father hornier than ever, who was struggling to control himself. Unable to reach the cum on her face she went right to the source, beginning to lick daddys fat cock, trying to get more of his juice, while lapping up what's already on it.
Her tiny tongue licking over his big tip was making him incredibly excited, if he could he would have forced his cock down her throat right now. But he knew that would hurt her, so he kept his thoughts inside his head, as his dick kept leaking and shooting pre in copious amounts, which were happily consumed by his own daughter. While having his cock worshiped by a toddler was incredibly pleasurable for Jon,  it was also a kind of torture as the toddler was gently coaxing more pre from his balls, while edging him just enough, that he was denied his orgasm for quite some time.
Luckily his girl eventually worked his cock long enough to just barely push him over the edge. Having been edged so long, he came so much and hard, the toddler fell over confused, as she was showered with his thick and sticky cum. Looking at her tumble over, he got worried for a second, thinking she might be hurt. However after a moment, she began to scoop up his cum with her hands and shove it into her mouth, having a big smile on her face.


Feeding his daughter like this quickly became a ritual for the pair. Sometimes if she was very hungry when he forgot to feed her in time, she would try to undo his pants to feed on his cum. And if he got horny when it wasn feeding time, more often than not, he went to get his daughter to help him cum, even if she wasn't hungry, she would do her best working his massive tool.
The first trouble in their new incestuous relationship began, when his daughter started to get her first tooth. He quickly noticed something was different, when she first began to chew gently on his cock instead of sucking and licking it like usual. At first it wasn't a problem, when the tooth wasn't quite there yet, even being weirdly pleasurable. But when the tooth came out, it quickly started to hurt when she bit into his dick.
But he was resourceful, so he didn't let that small issue stop him. His baby girl needed to be fed his cum, since he hasn't purchased any formula since the first time he nursed her with his cock. But since she couldn't help him cum with her mouth anymore, he had to find alternative means to reach orgasm using her body. 
So after some careful consideration,  how she could be of best use to pleasure him he had decided. He gently held his cub in place, as he slowly began grinding his cock against her tiny entrance. Having developed even more explicit desires for her body, the thought of more conventional means of reaching orgasm, didn't even cross his mind. In the back of his head he knew it was wrong to take things further, but now he had the perfect excuse to finally indulge himself. Even if he just needed that excuse for himself, since no sane parent would have even taken that first step of feeding their children with their cum.
Even though he knew he couldn't fit his massive cock inside her virgin entrance yet, rubbing against it felt incredible as well. While watching his dick grind against her, he noticed she was enjoying herself as well, giggling and even trying to grind herself on his cock as well. He even began to feel the friction lessening, as her premature cunny managed to get wet. All this pleasure made him feel like he was losing his mind, so he began grinding and thrusting harder and faster against her pussy. This forbidden act continued on for some time, as moans could be heard throughout their house, until he was slowly getting close to blasting his load. When his orgasm washed over him, he was so lost in pleasure, that instead of feeding her, he began grinding and pushing his tip against her pussy. As if he wanted to penetrate her, he made quick and short thrusts, barely parting her lips, making him blast his load. Shooting his cream directly into her virgin tunnel, flooding her pussy until it even went deep into her womb, trying to impregnate her undeveloped body.
It was too much for the toddler, as cum filled her womb, her belly inflated slightly. Being filled to the brim, the excessive amount of hot cum started leaking and shooting all over the place. Only after his orgasm had passed and his girl was covered in creamy jizz, did he realize what he just did, missing the point and just using his child to pleasure himself. However his nerves calmed down quickly, as his beautiful daughter crawled over to his still throbbing cock and began licking it clean. Once he started doing this once, there was no holding back in the future. It was just too exciting to fill his child with his cum, even though he couldn't penetrate her, it was still an incredible feeling. 
Even though there came a time when his conscience got a hold of him and he tried to stop using his child for his pleasure, as feeding her has become of a more secondary nature. But it quickly became a giant failure, as his daughter began screaming, after he tried to explain that they couldn't continue doing it anymore. Even he found he had trouble stopping, as he was no longer able to orgasm by himself anymore, he could only cum with his baby helping him.
So after only one long exhausting day, did he give in to his daughter's begging and his own incestuous desires. During that day his little girl even went on a hunger strike, not wanting to feed on anything but her daddy's tasty cum. And after he was continuously feeding or filling his daughter with his cum, emptying his balls at least several times a day, he had forgotten just how much cum was being produced in his balls. 
When his daughter finally had the tip of his massive cock inside her small mouth, he almost came at an instant. His balls were so full he started blasting such a massive load, she was thrown back by the sheer force of it, as he continued to paint the living room with his steaming cum. The smell of his giant load as it was  all over the room was so strong, he could never fully get rid of it, making this his daughter's favorite room. To this day he would find spots of dried cum, he missed when cleaning this gigantic mess.


As time passed his daughter grew older, growing up meant moving on to preschool. Which was all good at first, their lives continuing as usual, just with more time restraints. For an unkown reason, their teacher thoughg is was time, that they had an early sex ed class. First hearing about it made Jon a little bit scared, his girl could blab about their forbidden relationship,  or even worse could hate him for what they were actually doing. 
To his surprise however, when his daughter came home after their first sex ed class, there was a special glow in her eyes. He didn't ask how it went yet, still being afraid, but his fears quickly vanished when it was time to feed her again. As they entered the room, his baby girl went ahead and to his surprise quickly took off all her clothes. As his mouth hung open she laid down, spreading her legs and putting her still very immature pussy on display, even going so far as to use her fingers to part her lower lips apart.
Jon was extremely confused, not able to fathom this kind of forward behavior from his daughter. So he carefully asked her, what had gotten into her all of the sudden, she simply explained, that she wanted him to "make sex with her". After further questioning his cub, he finally found out, that after she had learned what sex was and got so curios and perhaps asked the exhausted teacher one to many questions. Who proceeded to tell the now sex crazed girl, that sex felt incredibly good for everyone involved, but unprotected sex was dangerous, as it could make you pregnant. But that had the opposite effect on the young chilf as just the thought of having her daddy's child made her even more excited to finally have sex with daddy.
He tried to refuse her at first, which resulted in her begging him even more, showing off her body. Even trying to explain to her that putting his big dick inside her tiny pussy would be very painful for her, didn't stop her begging her father to fuck her. So like every perverted father would, he gave into his daughter begging, both not wanting to disappoint her now that even wanted to do with him, what he was only dreaming about, making him unable to control his raging boner inside his pants. He already knew their relationship would never be normal and that if he would fully accept that, he could start enjoying it a lot more.
At first they tried to take it slowly,  enjoying themselves like they usually did, so their foreplay contained a lot of him nursing her, or, fingering and stretching her entrance. But eventually they both couldn't hold back their lust any longer. As he took hold of her tiny body, she felt so small and frail in his hands. He stopped for a moment before lifting her up and placing her on the tip of his cock. When she put her feet down, she had to place on her daddy, standing barely tall enough that the tip of his tool didn't penetrate her yet. 
He told her to lower herself slowly, so she could get used to having such a massive dick inside her cub pussy and reducing the inevitable pain. But she didn't have any other reference thinking it would fit, like the teacher had told her, so like always she didn't listen to him. Deciding she wanted it all, she just let her feet slip away, practically falling on top of her daddy's cock with her entire weight.
Making it a decision she quickly started to regret, when daddy's massive cock started to force its way into her no longer virgin, but still immature tunnel. She screamed out in pain, as she tried to stop herself, but it was far too late, she slipped and fell the rest of the way, until her butt was stopped by her father's lap. So with just one thrust, or rather fall, Jons thick member sunk all the way into his daughter, even pushing past her cervix and into her tiny womb.
She scrambled to get back up, tears streaming down her eyes as she tried to suppress her instinct to cry. But suddenly her father hugged her tight to his chest and whispered calming words of encouragement into her ears. This very moment she felt the worst pain of her life, as her organs were pushed aside by a cock never meant to be inside a child. However her fathers calming words and loving embrace, helped calm her down and soothe the pain over time.
For Jon on the other hand it was the most incredible feeling he had ever experienced, even better than any time he's been with his wife. The extreme tightness around his cock, as her virgin cunt felt like it milked his cock, while in reality it was trembling in pain. The most incredible thing however was watching his cock stretch out her belly, which shook with each of its throbs. The hug was to calm her down and ease the pain, but most of all, it was also because he couldn't let her go, the pleasure was too incredible. So even as his child still had to calm down, he slowly began thrusting inside her young body.
He felt like he wasn't in control of his own body anymore, in truth however he knew he wanted it so badly, even she begged him to stop. His rampant lust had clouded his mind and would have turned him into a rapist, but luckily for him, his daughter eventually got used to it, as she really wanted her daddy to love her and make her pregnant and even began to enjoy it as well over time. 
All in all he was taken of guard, by just how incredible it felt to finally fuck his own child, especially with her being barely old enough to go to school on her own. Sure he had imagined how it would feel like quite a few times in fact, but he couldn't have expected this. Lucky for him and her, as otherwise he wouldn't have been too scared he would hurt her too badly to act upon it, since he wouldn't have cared too much about it. 
But that didn't matter now, as he was finally able to do what he longed for even as a boy. Her young body shook with every thrust of that massive cock he made inside of her. She was barely able to cling to reality, as her body was shaken with pain and pleasure simultaneously. Trying her best to stay calm, as she stared at her belly horrifyingly distaning with each of his thrust. Even though she was scared, she managed to put her hands on her belly, so she could feel his dick stirring her insides, while rubbing it with her hands, when her daddy pushed inside of her.
The room was filled with the sounds of their bodies colliding and the smell of sex. From an outside perspective her body would have looked comically small compared to her fathers, as it was bouncing on his lap, as she was barely a preschooler, while her father was above average in size. Lucky for them, no one would witness their forbidden act of love and contact the authorities, as the curtains were closed most of the time, because of that very reason.
Jon was so overcome with pleasure, that soon he felt his orgasm rapidly approaching. So he kept living out his fantasies, as he put his hands around his cub and quickly lifted her up his entire length. She looked at him confused, for a split second, thinking he was already done, before she actually realized what he was about to do, as he pulled her bag down with one thrust. She was still so young and small, that she was light enough for her father to use her almost like a sextoy. The fear of hurting her had disappeared a long time ago, so he was thrusting and pushing her recklessly on his cock, giving him an even greater pleasure than he thought possible.
But sadly everything has to come to an end eventually. He knew before he began fucking her with reckless abandon, that he wasn't going to last for long. So with one last shove, he pushed her down on his cock, getting his entire absurd length back inside of her body. His cock penetrated her now loose cervix with ease and pushed deep into her immature womb. 
The massive load his cock began to unleash, was a thing to behold, perhaps even bigger than the one which messed up the living room. This was the first time his cock was actually inside his daughter and with her incredible tightness clamping around it, there was no chance for his cum to flow out. So as he was pumping his thick seed inside of her it had nowhere to go, so he could watch as her belly shook and inflated with each stream of cum he shot inside of her. When he was done, he looked at his daughter who looked like one of his used condoms, being a big round ball, filled with his cum, her other features barely noticeable. Only with a now clear mind did he notice that she had passed out during all of it, having climaxed enough times to drench him in her female juices. So he kept her close to him, as he pulled out and stared in awe as her small cunny wouldn't even let a single drop leak out. Taking a small nap with her body hugged tightly to his...


Sadly for the both of them, it took quite a few more tries for her to finally get pregnant. Mostly because she was still to young to actually have a child at that point, but sex definitely became a regular and often practiced part of their lifes. Which led to a pregnancy eventually, giving him another child, to repeat their incredible story once again.
