I have, on occasion, used pics from people I know in stories, either by accident (before I became friends with them) or after, either as the very occasional gift, or commission. I’m hesitant to share the reference stories though, without their permission, because most of them weren’t advertised as them. That said, if we’re in the same networks, you might recognize a few folks in photo captions here, or over on my now defunct side blog, @brackenousjunk.
There is, also, one picture of me on this blog, in a rather compromising situation, taken by a good friend of mine, also on tumblr. Consider it an easter egg, if you know me well, and know what I like irl, you can probably guess.
