John furiously beat his arms in an attempt to get to the surface. Suddenly, he hit something hard and slippery. A very tight and warm sensation engulfed his head. He opened his eyes, but all he saw was darkness. Then he felt the sensation getting tighter and he began to move upwards slowly as something pulled on his head. He suddenly realized he was in the orca's ass. He pulled with all his might, but the orca's tailhole was too tight around his head. The orca's ass had never been stretched this far before, and thus it was new and the hole was not stretchy enough, but it was slippery. The orca's muscles rippled and John was sucked in to his chest. Strangely, he could breathe in here, but the smell was overpowering and John fainted. The orca devoured it's victim slowly and deliberately, enjoying every second of this new experience. Finally, after about two hours, only John's feet stuck out of the orca's asshole, and the orca held them there for a few more hours, swimming around the tank, enjoying the pleasure of having a human in it's ass.
