You bask in the afterglow of your spontaneous jerk session with your cock still covered in a mixture of gooey cum and rancid shit. The muck still felt lukewarm against your member as dollops of it drooped onto your shaggy green coat. Its foul stench steamed to your nose and, although you should've been disgusted, the smell prickled you in a blissful way. Soon after your transformation your own poo had proven to be irresistible, it just felt and smelled so right.
By now you had sobered up and you began realizing what was happening. You couldn't deny that the experience had been quite exhilarating but you were also frightened of losing your humanity. Your old behaviors were snapping one by one and were being rewired to accommodate your new bestial instincts. In this moment of clarity you knew your mind was only regressing further so there was no time to waste. Your previous search for any potion or gadget that could undo the change had ended up fruitless. How could you get out of this mess? The shopkeeper of course! He would know what to do. After all it was his store filled with his magical crap that had caused this.
Your bold brows were pressed together and drool dripped from your lower lip when your face finally unfroze from its dumb expression. Trying to hold onto whatever was left of your humanity, you lumbered through the aisles of the store slouched over and with your hands dangling about. Every step you took resulted in a resounding thump followed by a tiny earthquake. The shelves vibrated, the bottles rang and the trinkets clattered throughout the store. When you finally arrived to the front a young man was cowering behind the counter, already aware of your approach. You came to a halt. Your swollen, oversized feet perfectly anchored your now towering yet unwieldy stature. As the store quieted down the employee opened his eyes and jumped into a straight stance and a forced smile. He asked "H-how can I help ... s-s-sir?" as he shivered with wide eyes looking you up and down.
You opened your mouth and let out "Ook-oo-ook-oo..." Even with your regained composure you weren't able to speak anymore. This was impossible. You freaked out as you burst into desperate shrieks "OOK-OOK-A-AAK-OO" all the while jumping in a maddening frenzy. Some nearby potions fell to the floor when you wildly smashed your fists on the countertop. The store clerk shrank back again only to respond "sir ... Sir ... SIR!" His cries finally made it back to your ears but you still landed a final hit on the counter out of pure frustration. When you folded your arms out of discontent he took a deep breath and said "Look, I'll just go and get the translator apparatus from the backroom. Just wait here and stay calm."
