Maria N. Lang writes the best futanari erotica ever. At least, one person thinks so. She has awkward shower thoughts that are sometimes about butts, and spends far too much of her time writing awesome, horrible, delicious sex. You should read some of it.
Maria has a newsletter that you should totally sign up for: http://eepurl.com/TSn7z
Maria has a blog that you could read if you feel like it: http://nymirra.blogspot.com/
Maria would stop writing about herself in third person if she wanted, but she enjoys it. She does what she wants. Which means she writes more and more futanari erotica, with a story. Tired of billionaire #940552? Biker #45923? Give Mariarotica a try. And tell Maria what you think, if you want: email@example.com
