Throughout the night you cooked in the butt of the poodle. It was horrible, all night the poodle added more shit to your ever growing mass, gas caused the pressure to really build up, and the whole time you were only inches from freedom. But as poop you don't have limbs, only a uniformed, brown, compressed mass of digested foods and bugs the dog ate.
Soon you could see light again through the sphincter and felt the poodle stir. The slimy tunnels around you jostled as the dog yawned and stretched putting its butt into the air, revealing your exit back into the world.
Once the dog had gained its footing, and finished yawning, the dog's anus released a loud, PHHHHPPPPPTTTHHHTTT, quivering the whole time. The dog feeling this pressure built up in its rectum quickly began to sniff the park area for a spot to go. After several moments, the poodle found an isolated spot near the roots of an oak tree. Quickly, the dog squatted and began to relax it's brown star.
Inside, your world went from still to back the still again and finally rested on forward. Your mass slowly crept to the anus as it inched open, you realised the dog was finally craping you out. You filled with cheer at this revelation and began to slip toward the exit, faster now. Gas began to blow past you as you neared the tailhole. Soon your head squeezed past the anus. Your "head" was free at last and now you could see your releaser. A black poodle, easy to recognize as male due to its loose hanging furry black sac which contained two golf ball sized orbs. Above you was the poodles fluffy tail and below that was the dogs gaping anus. You were free at last.
