Savvie and Lacey is a free web comic, about two women who have a D/s relationship.

Story of a Pet Elf (http://orgymania.net/orgy/) is another free web comic, with D/s. This one actually has sex in it.

I LOVED Savvie and Lacey! Really cute. I bookmarked this site, which is something I don't often do. The palindrome thing cracked me up!
