It seems a lot longer going back to the Magyck Shoppe, but you can barely take your eyes off the oversized bulge in your pants. You cannot wait to see what other magical enhancements you'll find. A few really tall guys walk by you looking down. You didn't so much as see as hear them, since your eyes are fixed on your bulge. You hear one mutter "Freak." You think, he should talk, he must be 8 feet tall, but he must have been jealous of the bulge in your trouser.
You reach the beginning of shopping district. The magic shop is the first or last on the block depending on your perspective, you count it as the first from the direction you're walking. You turn to face the small shop, and it seems to have become a skyscraper. You look up at the castle-sized door. It suddenly dawns on you that you and your clothing shrank. Your cock didn't grow. Looking around for a reference to your actual size. You soon conclude that you're only 6 inches tall, instead of your former 6 feet. That means your cock is only 1.5 inches long. You realize that you must have been shrinking as you walked over here, which is fortunate, as those basketball giants would probably have stepped on you if you were this short then. You panic. Maybe you're still shrinking. You pound on the immense door. Finally, you take a running leap and catch hold of the edge of the mailbox slot cut into the bottom of the door. You pull yourself up and swing your body onto the ledge. You lie flat on your back realizing that the 2 inch thick door is now like 2 feet wide at your current size.
Before you can rollover and drop down into the shop. Your world trembles. A giant is opening the door to enter the shop.
