Mike is a fairly good looking, middle aged bengal tiger. His wonderful wife had given birth to their precious daughter only a couple of days ago. He thought his life would change for the better with a child, but it took only a few days afterwards, for his entire life to fall apart. Until then his small family had been as normal as can be. Most of their friends were thinking of them as boring since they never did anything out of the ordinary. Their biggest achievement and adventure was buying their small house with a loan, with some help from their parents. 
Mike was happily married to his wife, never even thinking of cheating or leaving her. Their favorite position being missionary, even his Wife often thought of their life as boring, but she enjoyed the security of a steady and normal life. So both of them were looking forward to being parents in their own way, Mike wanting a child and his wife the excitement of change. But none of their plans had worked out the way they had planned.
The reason for this abrupt chaos was their very unusual daughter. The toddler would have passed as a regular tiger cub, if it wasn't for a massive cock and an equally impressive pair of balls between her legs. A female with a dick wasn't an unheard of mutation  but the size of her dick was the reason for many tests in the hospital, but the doctors could only tell them that their daughter was healthy and that it wouldn't be a physical problem for her. 
There was a small tight cunny hidden behind her balls as well, but they only took notice of it whenever they bathed her more thoroughly. Which had to happen quite often, since her dick and balls dragged on the ground when she was crawling around and also developed a strong musk. Her dick was easily twice as big as her body when flaccid, growing to thrice her size when erect, while her balls could easily pass as beach balls.
And then Mike's wife had left him and their child only days after giving birth to her. The story the destroyed father told his friends and family was that she couldn't handle their daughter's additional parts, especially their size. Elaborating on how she kept calling her a monster and a mutant. 
But as was often the case with a breakup the truth wasn't as simple or even close to his story. What had actually transpired was that while she didn't particularly like the fact her daughter dragged a massive dick around, she could have dealt with it and perhaps even grown to love her despite that. While Mike didn't take any time to love their daughter, as he had discovered a new desire once he first laid eyes one it.
He was in a constant state of arousal whenever his daughter was around, growing hard the moment he lays eyes on her dick and balls. And since he was her father he was making sure he was around her a lot, lucky for him his wife didn't take notice of his erections. She had thought he was overprotective of their child and took the time for herself, feeling lucky that he took over most of the work besides feeding her. 


One day however Mike was taking a lot longer to wash the toddler, so she went to check on them to see if everything was alright. That day Mike had succumbed to his desires and went further than just cleaning her. When his wife came inside he was so entangled in worshiping their daughter's massive throbbing cock, that he only noticed his wife once she began screaming.
After that she couldn't look Mike in the eyes anymore, she felt like she had no one to turn to, since her friends wouldn't believe her crazy story. So she grew more and more desperate every day after that, she even caught them a second time only a day later and every day after that. 
Since he knew he was caught, Mike didn't try to mend or pretend but just let go of his inhibitions, rubbing and massaging his daughters shaft whenever he could, or shoving his face inside her big soft balls. So eventually his desperate wife just packed her things and left, running away to be never seen or heard of again.
Having no one to correct him, gave him the opportunity to convince everyone of his story. He was earning their sympathy and support, even though he was the real reason their marriage was wrecked. He didn't even feel bad about the situation, Mike's mind was already so twisted by his daughter's body, that it didn't take long to forget about his ex, or what he had done to her.
Now that he was left alone with his daughter, he could spend as much time as he wanted drooling all over his child's assets. So while his friends worried that he wasn't moving on and going out again, messing his chances while he took care of his daughter, he spent his time fondling or stroking his daughter's dick, eventually beginning to work a finger or two into her tight pussy, slowly preparing her for his own dick. 


The day after his ex had left, he was confronted with a new problem. His daughter was crying from hunger and since she had breastfed her until now there was no formula in the house. He was about to head out to go and buy some as fast as he could, but when a thought crossed his mind Mike's dick became hard in an instant and his perversion led him to try an alternative way to feed his daughter. 
At first he began to play with her dick as usual, trying to make her stop crying which usually worked. He cock slowly began to throb and grow to full hardness as her body struggled to fill it with blood but it worked somehow. He could smell the intense musk as he had decided to forgo washing her as often as his wife had demanded. He took a deep breath to fill his lungs with the sweet scent, his own cock reacting by throbbing and shooting pre, signaling it was ready to do its part.
He sat down in front of her and placed her head gently on his lap observing her reaction to his dick being almost right up to her face. Her nose began to twitch as she smelled her fathers scent, and began to slowly work her way closer. When her eyes met the leaking tip of his dick, her instincts told her to suck on it, filling her starving belly with it. So she latched onto her daddy's throbbing tip like a nipple and began to suck on it. The taste was unusual and made her scruff her nose, but she was too hungry so she kept going regardless.
Mike let out a loud moan as he felt the toddler nursing on his cock, making it leak more and more pre, which she eagerly gulped down. Not wanting her to have all the fun he leant forward and began stroking her massive cock, being almost as big as her entire body. In response the monstrous tool began to harden under his touch. 
Just imagining what size it would grow to when she reached puberty made him shoot a big load of cum inside his daughter's mouth. Big enough to inflate her belly a little, his own tool being respectable as well but nothing compared to hers. So having fed her most thoroughly he put his entire attention towards that throbbing veiny cock of hers. He knew he couldn't fit it inside of himself but even if he could that didn't interest him, but there was something about worshiping such a massive tool.
Even her balls were huge and heavy even if she couldn't produce any cum yet. He often used them as pillows when they were cuddling. Thinking of what he was going to do next made him remember the last words he ever heard from his ex wife: "if you love that dick so much why dont you fuck it!" He was sure she wanted to spite him but it had given him a new idea the past few days.
He placed his daughter's cock and her body on top of a table and then stood in front of it. Lining up his throbbing dick with hers made him drool both from his mouth and cock. At first he tried to move slowly, so as to not hurt his young fragile daughter but right after the tip of his cock disappeared so easily inside her urethra there was no holding back anymore. Roughly grabbing her cock he began forcing the rest of his  fuckrod inside of her peehole. He saw some discomfort in her eyes but even if she started crying he couldn't stop himself anymore. 
It was an entirely new sensation having a cock wrapped around his own, it was just as tight and warm as a pussy but the texture was different and he felt each pull and throbb more vividly than ever before. He was already getting close and he hadn't even started for real. But when he tried to hold on it proved a fruitless endeavor as he quickly reached orgasm and started blasting his load down her tube.
His tool being impressive in its own right, produced enough cum to inflate her balls as he moaned her name, while he forced her to take his load. Watching that made him curious, wondering what would happen if she orgasmed now that his cum was inside of her. He pulled his dick out and was about to wrap his arms around her massive dick.
However a new thought had crept into his mind, a new much stronger curiosity or was it perversion? What if he kept using her like this without letting her release his seed he wondered. So until he wanted to have more fun with her in this way he would have to stop himself from playing with that massive dick again.


A couple days later, he was fucking his new sextoy again, his perversion having removed any kind of fatherly love and replaced it with pure desire. No longer a daughter to him but a plaything for his desires. She no longer felt any discomfort from it, seeming more excited and playful whenever he had his way with her throbbing mass, not being able to understand what he was doing to her. Her balls had swollen massively in such a small time since he had emptied himself inside of her multiple times a day. She wasn't able to move around on her own on day two, the weight of her balls being too much to bear. 
Having fucked his daughter in the same room for days without washing her or moving her outside, left the room drenched in her musk and the smell of sex. So his lust decided today would be the day where he would allow his daughter to finally empty those massive balls. But first he still had one last load to give to his daughter. Her dick had gotten a little looser over those couple days because of his regular usage. When he wasn't inside of it, it was left gaping and dripping with his leftover cum, which didn't quite make it down the massive length into her balls. The advantage being that she was always well lubed up and prepared for another round.
He hadn't masturbated by himself ever since and what use did he have for it anyway, having such an easily accessible hole at his disposal. Even easier than his wife, since she was too young to even talk or fight back, so there was nothing holding him back from using her like a tool. He didn't even have to use foreplay anymore, her dick seemingly hard all of the time at this point. The rope he had tied around her cock to keep her from cumming certainly helped with that.
The heavy scent from their combined musk seeped through the door and the sound of his balls slapping against her tip filled the house. He already felt himself getting close, the thought of seeing her cum for the first time in her short life driving him wild. He moaned her name as he started to blast his load inside of her, even bigger then the times before, emptying his balls thoroughly, but even then hers didn't grow by any noticable amount at this point.
He was left panting as he recovered from his orgasm, his dick still throbbing and dribbling a few more drops of cum inside of hers. But when he was about to pull out, he suddenly heard a rumbling sound followed by a gurgle. When he saw her balls move and felt her dick tighten it was too late for him to get out of the way.
Before he could fully comprehend what was happening he felt a force push his dick outside and hit into his pelvis. He was shot back, as what felt like thick and hot goo was shot all over his body. He had to fight for air as the relentless stream was covering his face, much of it going into his mouth forcing him to swallow his own recycled seemen.
From an outside view one would have seen how the biggest cumfountain one could imagine, shot out from a toddlers giant cock. Her balls deflated with every second as the stored cum was forced to shoot out. The poor man standing in front of it was flung back and thrown on the floor as the relentless stream of cum was covering him while flooding the entire room.
Once it was over and he could get back up on his feet he was gasping for air, his belly filled with his cum he had to swallow, being slightly rounder than usual. When Mike had recovered and began to look around he saw that he was standing knee-deep in cum and both him and his daughter were covered in seed, the world was just white around him. Her balls were mostly back to their original size, only sagging very noticeably now.
All he could think of was how in the world he could clean up a mess like this and how much he wanted to repeat it.
