Sexy Ballpoint Pen Art (13 pieces - NSFW)

Juan Francisco Casas' Bic pen drawings are definitely better than the doodles I used to make in high school. Recreating sexy photos with the blue pens that we all use in our daily lives, the Spanish-born artist creates large scale murals that measure up to 10ft high. Casas can use up four 14p ballpoints on one picture, and his award winning pieces fetch over $6000.

"I guess it started off as a joke, to try and make something so realistic that people would think is a photo," Casas said. "For me it's not that different from painting. I was trying to show that it doesn't matter what material you use, it's what you do with it."
