The wolf raised his heels. He could feel his gut talking to him in gurgles and gargles, complaining to him over the massive load working its way into his overstuffed colon.

"Uuuggh..." the wolf groaned, and the tip of his pointed cock came peeking out from the slit in his sheath. "Why does it have to feel so bad... and so good?!"

The wolf cringed all over, and the hairs stood on end as he felt his puffy asshole distending outward, as if preparing to lay a gigantic egg. "Oh no... UGH!" He gritted his sharp teeth, and growled as he felt his anus begin to stretch around the hard bolus.

"AGH! SHIT!!!" The wolf began to moan, and howled as the end of the giant, hard log of shit began to slide slowly out of him. He shivered and heard the way it moved, wetly squelching as whisps of air squeezed its way past the hard, impossibly large boulder!

"AGH!!" He shouted again, rocking back and forth, and tried to clench his ass and stomach to push it from his ass. It was as if he were giving birth! It was birth to a thick, heavy, and solid brick. Tears began to gather in his eyes as it slowed to stop half way out of his ass, turning his anus bright red where it threatened to snap like an over stretched rubber band.

"UNH.. FUCK.. GET.. OUT.. OF ME... UH!!" The wolf screamed, and his cock swelled thick, and the knot inflated at the base. The wolf convulsed briefly as orgasm shook him, and cum came welling up and out of his vivid, red rocket. White, sticky jizz went flowing like a fountain into the air, and spilled over his balls to splash the giant log slowly inching its way out of him.

The wolf began to pant, and his breath was heavy. He shook all over as his belly clenched, gurgling loudly, as if it was also moaning with him in the middle of his orgasm. His eyes rolled back into his head, and drool began to seep down the wolf's cheeks as the last of the massive, stone-like shit finally came rushing out of him! It was an enormous relief, and it made the wolf tremble all over as it finally vacated his colon, and left him stretched and feeling as though it had taken all of his innards with it.

The wolf collapsed, and caught his breath loudly, his asshole quivered and squeezed the bottom of his colon where it had begun to poke out of him like a vivid, pink sleeve."
