Ready for a Shower, and My First Shading Pic

This is a little sign of what new naughty pics I going to post later on. Nikki, Caitlin, and Jen all going to girls' shower room. And also, this is first for me. I wanted try out characters in shading after seeing some of my DA friends using shading for their drawings. I included both version of this, one with shade, one without, to see if you want me to do a 3D effect for my future drawings or not.
