Is She Filthy? (Yes.)

Have you ever caught the eye of a girl on the street and found yourself wondering what she's like when the lights go down? Amateur porn blog Is She Filthy? is betting the answer is yes.

Like Guess Her Muff, Is She Filthy? presents visitors with a G-rated picture of a girl, then gives you the opportunity to click through and discover her naughty secret. Except the question really isn't "Is she filthy?"—because they're all filthy. (Seriously: not once did we click through to find a picture of a girl drinking tea and playing Go Fish! with her mom.)

Then again How Filthy Is She? doesn't have quite the same ring, now does it.
