Renderotica

I'm wondering if artists typically work on commissioned pieces that fit a specific kink or if you just have to hope they do it for the larger audience. My kink would be fully pregnant women, particularly in outdoor settings and/or remote locations. I like the look and idea of pregnant women alone, playing with toys perhaps and particularly having orgasms while fully pregnant.  My kink usually is not havng any other partner in the image. I like the idea of pregnant women going off to play in risky/outdoor places alone and love series of images where it goes from dressed to full nude orgasm.  Is this something I can commission if I approach individual artists or is this wish list the best way to hope someone creates things?
