The Cushy Pen is a pay site for diaper art. A lot of the artists just draw humans, but there are some top-notch furry artists in there as well, including mifmaf, kalida... and me! It's a new site, but I think it definitely promises to become quite a full archive of cute guys and girls in diapers.
I myself will be focusing on the furry gay crowd (though I'll certainly toss in some females now and then). If you join, you can expect some high-quality, high-res diaper art from me and the other artists. They've even asked me to do a comic some day.
I promise not to flood my gallery with teases and previews for this site. That annoys the hell out of me too. This is probably the only teaser you'll see for a very long time.
I'll be doing my best not to let this interfere with my commissions or comic work.
