The Windsinger, deity of the wind, certainly wasn't expecting a guest. And out of all guests, he wasn't expecting the deity of lightning, the Stormcatcher.
"Windsinger, I have come for more than you think. I am in heat and I cannot find a willing female. So, how about you?" boomed the Stormcatcher.
"I-I-" began the Windsinger, but he was cut off when he saw the sheer size of the Stormcatcher's cock. The deities were all huge dragons, but the Windsinger didn't know their cocks were so big, despite being a deity himself. His own length looked pathetic against the size of the Stormcatcher's, as long and thick as a mountain.
"Surprised? You know us deities can change size. Now, bitch, I demand you change your own size. Become smaller than my cock. Make it seemingly impossible to fit. And I will show you the impossible."
The Windsinger knew better than to anger a God of storms, so he obediently shrunk to a size smaller than the mountainous cock. Without any warning, the Stormcatcher rammed the first couple feet of his cock up the Windsinger's ass. The Windsinger began to moan in lust and beg for more than just a taster of the over a thousand foot cock.
With a mighty roar, the Stormcatcher shoved over half of his length into the Windsinger, who's serpentine body was now beginning to stretch to accommodate the length. The Windsinger doubted he could take any more, but all his doubts disappeared in a jab of pain as the full length slammed into him, his body bulging and the Stormcatcher's balls slamming his ass.
Surprisingly rapidly, the Stormcatcher pulled out, but then slammed the entire length in at once, causing a scream from the Windsinger. He began to pump at a steady pace, but the Windsinger begged for more and he sped up rapidly.
The huge cock filled the windsinger, leaving him so overly full with every quick thrust. He came on the floor but that was nothing compared to the load the Stormcatcher's swelling balls had to offer.
With a crack of lightning, the Stormcatcher roared and unleashed gallons of warm, sticky cum, filling the Windsinger and swelling his body.
"Smaller, Windsinger." he ordered.
Now enjoying it and wanting the most possible, the Windsinger shrunk to 1/50th of the size of the Stormcatcher's cock. But then, the Stormcatcher grew even larger, his cock swelling to new lengths and new thickness until the Windsinger was 1/100th the size of the huge dick.
With no mercy, the Stormcatcher shoved the entire dick into the tiny Windsinger, and it fit. The serpentine deity stretched beyond belief, body still full of cum as it wrapped around the cock that pushed in and out of it with such force and speed that it seemed unreal, if it wasn't already unreal enough.
This went on for not just hours but days. Days and days of rapid pummeling, the Windsinger screaming in delight all the while. Occasionally, the Stormcatcher would grow larger or the Windsinger would shrink more until it seemed even more insane than ever.
The pleasure was immense, the rough dick filling the Windsinger, blotting out his senses and turning him into a mindless slave to the huge cock. It slammed in so fast that there seemed to be not even a nanosecond without a thrust in it. Lightning caused the cock to tingle and vibrate, providing more pleasure for the snake taking the gargantuan length.
Finally, the Stormcatcher unleashed the biggest load imaginable. An endless stream of cum bloated the windsinger like a balloon, all the while still being pounded by the massive cock.
The warmth provided so much pleasure, it was a shame it ended. But they knew they would do it again.
