Because he’s about to outgrow the planet. Commissioned by [Xazzon](https://www.furaffinity.net/user/xazzon). --- Plenty of jokes have been made about animals in Australia being extraordinarily deadly. While most wouldn’t rank cockatiels among the most dangerous creatures down under, Xazzon would soon place the *planet* down under his [underfluffies](https://www.urbandictionary.com/define.php?term=Underfluffies). Though his base size was just twice that of the typical wild cockatiel, he had two major advantages over his feral brethren: He was sapient. And he could grow. On one day, for reasons known only to Xazzon, he decided to push his growth much further than normal. He occasionally became a few dozen times larger to threaten a human that was messing with the wildlife but, today, he wanted to see just how big he could become. He flew to the forest’s edge and hopped into a field so he’d have much more room to grow. The cockatiel folded his wings against his back, looked towards the sky, then ascended towards it without ever leaving the ground. Xazzon’s size doubled every few seconds. Within a minute, he could see over the forest he usually inhabited. He lazily walked away from the trees as he grew; every step left a long, [zygodactyl](https://e621.net/wiki_pages/18249) print in the ground, each markedly larger and deeper than the last. His black, four-toed feet initially left shallow footprints as if the dirt was damp sand, but, as his size increased, his steps left ever-deeper imprints. Earth soon yielded like wet clay that detailed every scale upon his soles. The planet’s curvature became obvious to the mega-sized avian and he was just getting started. Cockatiels commonly roost in remote areas of the Outback. There were only a few humans around and none had a cell phone signal to communicate what they were seeing. Colorful yellow feathers, each taller than trees, were the first to peek above the horizon. The bird’s orange face was like a sunrise as it came into view; some swore Xazzon’s red cheeks were blushing. Those nearest to the bird felt his footsteps; the massive avian caused earthquakes measurable for miles every time he touched the ground. Those same humans were the first to discover the bird’s arousal as well. A tapering pink erection jutted from Xazzon’s cloaca. Its base was as thick as both of his legs; its length matched the size of his feet. Every heartbeat caused his shaft to rise against his belly before gravity pulled it down. His size meant that precum couldn’t bead on his tip but, instead, a waterfall of sexual fluid carved a canal on the landscape below. Some of that precum stayed within the banks of the newly-formed river; the excess was a viscous, slow-moving tsunami that engulfed everything in its path. Xazzon was dozens of miles in height by the time news of the giant cockatiel reached major cities. He was too big to stop. He was too big to meaningfully injure. All the world could do is watch, wait, and hope he would choose to spare them. His vocalizations, which had thundered across the continent, went silent as he outgrow the planet’s atmosphere. He casually hopped forward and landed with such force that the entire planet trembled. Cockatiel feet are large relative to their body, which allows force to be spread over a much wider area. While that limited the intensity of the earthquake at any one place, the vast surface area of his soles caused those quakes to happen for thousands of miles around. All of Australia saw Xazzon within the hour. His cock hovered above the Northern Territory, much as a human’s finger might point at a map, while his feet flattened half of North West Queensland and a quarter of Western Australia. His dick resembled a pink, fleshy mountain range, with river-like veins carving along its length. He wanted to *feel* the planet, though, rather than merely looming above it, and decided to sit down. Xazzon’s dick shattered the sound barrier as it moved several miles per second towards the world below. Everything swiftly darkened for those directly beneath him until he reached the ground. The Northern Territory wasn’t just flattened; the world reshaped itself by molding to the shape of his cock. New mountains formed along the sides of his shaft and white–precum rapids rushed from its tip. Much of Southern Australia was similarly terraformed to accommodate the cockatiel’s chest. The Arafura Sea was plunged into twilight as Xazzon’s tailfeathers blocked out the sky. Australia had been reduced to little more than a nest for a giant, horny bird. To Xazzon, though, this was all foreplay. His cock—and the entire planet—slowly rocked back and forth as he used the Earth as a masturbation aid. He leaned forward to try penetrate the planet’s crust, a task that would only become easier as he grew and his precum saturated the ground. When would the bird be satisfied? Only he knew how large he’d get before he’d get off…
