Coloring books for adults are all the rage these days, and I’m so glad that the adult industry decided to embrace the trend with books packed with XXX-rated scenes to colorize. Duke’s Naughty Coloring Book’s “For the Ladies” edition stands out with imagery that’s perfect for ladies who love cock. Filled with sexy scenes of hooking up as well as buff men in all their glory, this coloring book focuses on the female gaze, which is very refreshing. I had so much fun coloring all the big booties and giant penises that filled the pages. Gift a copy of this coloring book to all of your girlfriends — they’ll be mesmerized!
