At the same time his brother was looking behind him and seeing both of his large fat gray sides, Lucas was drawing a big black tube shape between his brother's hind legs with the addition of large black balls. It was so large, it extended nearly the entire length of his underbelly.
*******************
As I was looking at my enlarged right side, I felt a tingling in between my now-hind legs. The tingling grew more and more intense. I felt my dick grow hard and long. And longer. And longer still. I then felt my balls begin to tingle and churn. I felt them drop, as if I was going through a second puberty but in extremely rapid time. The shaft of my dick kept growing, and it had such an intense feeling. I tried gripping it. But all I was able to manage, was lift my left foreleg up. I had to immediately put it down with a "clop!" as my upper body was so heavy and my spinal cord unable to straighten back upwards in support of my newly added girth. My hips locked in the position of a quadrupedal species.
Unable to relieve myself with the continually growing intensity, I had to close my eyes yet again. Grimacing. Until the feeling subsided.
Still hard, I look down between my front legs. There, greeting me, was a huge black wobbly monster with a large dark hole pointing straight at my face. I was horrified! All I could do was stand there, looking at this thing in shock. That was now mine! It was attached to me! Everytime I made the slightest of movement, that thing would wobble two and fro. Back and forth. Before settling back into its forward centered position where it belonged.
"Please. Oh please stop!" I said in rising panic as my breathing became more rapid and labored.
Looking frantically around myself, only able to catch glimpses of my now apparently enormous rearend before I was forced to step sideways with my front legs and straighten back out again. My movements and flexibility restricted to that of a fat four-legged donkey. Which I now apparently had instead of my nice this, flexible human body I was originally born with.
I wandered over to the mirror. The only option left to me walking on all fours and with the natural clumsy movement of a donkey. There was my face. My head. Attached to the body of a donkey, and crowned by long, broad gray ears. Ears that would twist and turn seemingly of their own accord. I was now all donkey below the neck and above the head. A fat, smelly one with a huge black monster between my back legs. And I was now forced to stand and move around like one.
I looked like a freak. A human head on a very short neck attached to the large body of a donkey. My head looked like it was miniaturized now. It was comically too small. I'm a total freak now!
"What the fuck!?" I said aloud, wishing I didn't look like some sort of crazy freakish chimera of human head and donkey body and ears.
