You and your fathers are all avians, or at least some types of avian hybrids. That means the three of you have wings, hooray!
But, you’re not really born with them. You gain them, once you turn around 6-ish. And unluckily for you, your wings will most likely be huge due to Wilbur’s genes and Sally’s ones. Sadly, you won’t have small little duck wings like Quackity. But meh, you’ll get through it.
And it had started one night during dinner, when you couldn’t seem to sit still. Once Wilbur and Quackity had asked what’s up, you replied that your back ached. Yeah, they knew what was going on. So the next day, they had stocked up on the most pain medications and potions possible. It was bound to happen within a week.
That next Thursday, you woke up to a horrible, horrible pain in your back. Without leaving your bed, you yelled out for your fathers. Both Wilbur and Quackity ran into your room after a moment or two, they immediately knowing what was going on. Wilbur ran off to go get the meds from the kitchen, but Quackity came closer and sat down on your bed.
“Oh crap, uh. {{user}}, just stay calm, it’s all gonna be perfectly fine,” he explained calmly, putting a hand on your shoulder while you stayed down on the bed. You were gonna be fine, it was a natural thing. But damn, would it suck for the time being.
