We ran - or, well, stumbled, in my case - until we finally reached a tall wooden, old and ugly shack near the park. Its tall roof allowed me to stand straight, so I was able to stretch...
Stretch... I was still getting taller! I had to be over twelve feet tall, and now my torso and legs were lengthening in conjunction... taller and taller. Hanley was half my height now. I groaned as the tingly feeling got even stronger. I looked down at Hanley, who was standing at my hips.
The feeling soothed for a moment and then restarted at my genital area. I peeked into my boxers to see my soft two inch long member sitting on top of my thumb-nail sized companions. I pulled my finger away and my boxers covered the sight yet again... but I felt something shifting around in there, twitching, lengthening. A strangely wonderful feeling surged through my genitals as my member got longer, still soft. I peeked and saw that it was about four inches long, still soft. It reached five inches... and still elongated and pulsated as I excited myself. Longer and longer it grew until it was about six inches long. Hanley was watching me, making me feel slightly uncomfortable. All of a sudden a huge burst of pleasure erupted inside me as my package got bigger at a huge speed. It was getting longer, really fast now. Seven, nine, eleven... faster... thirteen, seventeen inches. Even more!? It was still relaxed... reaching twenty, twenty two...
Hanley's head touched my boxers as the components inside reached impossible size. Twenty five, twenty eight... thirty inches. Upon looking inside my boxers I was amazed and pleased at the growth. It stopped at about thirty six inches long... I had never even imagined this! The two pieces underneath my impossibly large member began to grow too... even quicker than anything else. They stopped at basketball size, taking up too much space in my small boxers. And my huge member began to harden as a result of my excitement, taking a break from its three foot length and quickly reaching four, hardening by the second.
Hanley was stepping back as he watched me grow, surprised at the growth he had not planned. My member was completely hard now... at forty eight inches? Four feet long? I stared jaw dropped at Hanley.
But the next changes had already begun. My stick legs began to thicken, gaining muscle and power fast. Knees the size of small television sets stood surrounded by unnatural legs that were as thick as tree trunks. Big tree trunks. My feet broadened and grew larger, now able to take the weight and size of my muscly legs... oh man, I felt so powerful. Walking was as easy as thinking now.
Then my arms felt that tingling sensation as my biceps grew to impossible sizes... my arms as thick as my legs! My hands were so big that I could pick Hanley up with no trouble at all - with one hand. I was so big, so strong...
But my head, shoulders and chest looked babyish in comparison. Soon, that changed as my shoulders slowly broadened, at snail speed. My arms were a foot away from my torso when my shoulders had stopped widening. My shirt had ripped long ago, revealing my two pectorals making their way in, the size of A3 sheets of paper, and my abs, which were harder than a rock.
All that was left was my head. I groaned more as the tingling sensation continued to flow at its strongest... and my voice was still pathetic compared to my body. I felt my throat get larger quickly as my neck thickened to huge proportions.
"Oh yeah!" I screamed, my voice now a loud, deep bass tone. A clearly visible beard grew on my pale face. I touched it - it was soft, perfect. My frizzy, boring hair was replaced by smooth flowing, longer hair that didn't quite cover my eyes.
The whole time Hanley was revelling at his creation, watching, with... popcorn? He had obviously made popcorn appear out of somewhere and was now eating it frantically. Once the tingling feeling receded he gave a big clap and I bowed, almost crushing him.
"Now what?" I asked, which led to Hanley needing to cover his ears as a result of my huge, booming voice.
"I don't know..." he replied. "How about we..."
