Maddy O'Reilly is an adult-film star. If you don't know of her yet, then you'll probably want to do some research. Ya know -- for science. We'll give you a minute.

Okay, you're back now? Miss O'Reilly is seriously one of the hottest girls on the planet. The 25-year-old played Dorothy Gale in Not the Wizard of Oz XXX, the pornographic parody of -- you guessed it -- The Wizard of Oz. Her seductive looks and sexy body are a dangerous combination and helped her become nominated for plenty of awards and even helped her win an AVN Award for the "Best Solo Sex Scene." See, fellas? She's beautiful and talented.

Check out her gallery below and become a fan of hers on Instagram and Twitter, both of which, as you might have guessed, are pretty NSFW.
