Alexander Warden
Estelle Warden

There was a time, like with most viruses, that QBE was not exactly taken seriously. It sounded outlandish, impossible, or to some people, like a damn good time.
To Alexander Warden, 16 years old and high on life, it was just a fun rumour that the internet was blowing out of proportion. He was a dragon, or at least mostly - his parents had long ago fled the scene and he wasn't about to track them down just to ask about his lineage. He was covered in short, soft black fur all over, except for a strip of golden scales that ran from under his chin to his crotch, and down the length of his long, prehensile tail. About 6ft even in height, not counting the curled horns of burnished gold, the tail was another 4ft in length, tipped with a bushy tuft of hair that matched the sandy blonde on his head. His eyes were a bright, glacier blue, with sharp vertically slit pupils, and he often said they were his most striking feature. In fact, they were what attracted his girlfriend to his side on a fateful night in late December, partying together under the strobing lights of a nightclub. The air was heavy with musk and lust, drunk teenagers grinding on each other with wild abandon, half dressed and a heavy drink in one hand. He knew nothing about her, other than the fact she was a gorgeous deer in a sweet sundress that rode high on her thighs, tantalising him, her roaming hands urging him on. She wasn't his first partner of the night, far from it, but she was the last; their chemistry seemed to be more than just mindless passion and they woke up tangled in each others arms the next day, a cheap rented hotel room trashed by their animalistic lovemaking. 
They exchanged numbers, kept in touch, learned more about each other in the following days, and poor Alexander fell madly in love. When his paramour announced that she was pregnant he was overjoyed... But it was not to last. Unlike his family, hers was most definitely still in the picture, and their control was insidious... Cruel. The couple's unborn child was discovered to be forming a shell inside the womb - a clear sign of QBE. They were both tested, questioned, interrogated and, finally, separated. Alexander's desperate pleas went unanswered and ignored, the strict religious zealotry of people who thought prayer and abuse could cure any "curse" meaning that he was all but banned from ever seeing his love again. 
In the end, he called the authorities, but they were too late to save the mother of his child. Starved and beaten, it was a miracle that the young woman held out long enough for the egg containing his child to survive... But there he was, holding a new life in his hands. Alone, but for his fond memories and a hope for the future.
He didn't care about the money he got from the lawsuit, simply handing it off to a financial advisor and burying himself into research about the QBE virus. It was changing his body, altering it at the genetic level, so what effect would it have on his baby? Would she have special needs, medical problems? Where would they live, what school could she attend, how fast would she grow? So many questions, never enough time. But he did his best, raising his precious daughter, Estelle, with endless love and adoration from even before she hatched. Her eyes were the same shining blue as his, fur black as night, save for the white spots that sprinkled her sides and back. Her tail was short and fluffy and wiggled happily all the time, her hair a glimmering white blonde, with the tiniest nubs of golden antlers on her head. She was also, much to her father's surprise, a full hermaphrodite - a tiny sheath and sac sitting just above her lady parts. 
With more than a bit of government assistance, he moved away from his current home and into a small detached house in a new QBE exclusive gated community. It had medical facilities, schools, daycares, stores, movie theatres... Everything one might need. He raised his daughter like any doting father would, giving her the best care he could afford (which was, by now, quite a bit) and showering her with love nearly 24/7.
Of course, Alexander did have his own, unique challenges beside being a single father. The QBE virus worked its changes on him, too; his sex drive had gone through the roof, his genitals had enlarged to nearly a foot in length, his testicles each the size of kiwis at their smallest and producing what he thought was an impossible amount of semen. Not to mention that he'd grown a whole additional penis, just as sensitive and needy as the first. He did what he could to resist the urges of his body, but the longer he waited the more desperate he became, balls swelling and straining, cocks constantly leaking until he relieved himself in his bathroom, making a mess of the shower with sex toys he'd purchased online in a fit of lust.
For a whole year, he fell into a kind of routine, but as with much in his life, it just wasn't to last. Estelle began to fall ill... She would no longer eat anything he provided for her, milk or soft food, and no medicine seemed to calm her. Terrified, he took her to the specialised doctor nearby and found that the cure was, while simple, quite difficult to stomach.
As a child born with the QBE virus, the nutrients normally provided by a mother's breast milk were... Rather unique. They could not be replaced by formula, or even by donated milk from another woman. The child's intake had to match generically with the parents... And unfortunately for Estelle, her mother was... No longer around. To Alex's understandable confusion, the doctor attempted to explain that the -father- could, and indeed must, contribute to the health of his daughter by feeding her. It would just require a rather different kind of "milk". Shocked at first, demanding a second opinion, his desperation gave way to a stunned reluctance before, eventually, acceptance. For the sake of his daughter's health, he found himself in his own bathroom, stroking his twin cocks with deep breathy moans, struggling to NOT think about his own little girl, until he exploded messily in his hands, shaking as he directed rope after rope of thick, creamy seed into the jugs he had prepared. More than a gallon of cum, carefully poured into a innocent looking baby bottles, the opaque containers and rubber nipples on the end giving the illusion it was nothing more than regular milk. 
To his surprise, Estelle took to the new feeding with gusto. To his relief, the effect was almost instant, calming and soothing the poor child, her health quickly returning. To his shame, the act of filling her bottles became more than just a necessary chore, his head swimming with sinful thoughts and flimsy excuses for why her face was constantly on his mind. To his credit, he lasted a whole year before he finally met his breaking point...
