Yes

You finally found the page and start to cast the spell. "I'm way to small and I wish for more. Give me more strength, make me......" You started wondering what size you should be. Not too big, and not too small. After about 10 minutes you have decided, "make me 5inch wide and 13inch length!"

All of a sudden you felt a tickling sensation. Your cock grew 6inches immediately. You pulled down your pants to see it when all of a sudden the lair door opened.
