I went a little bit too ambitious with this sketch. 2 characters I can do, but 5 is too much for a daily sketch. If this one wins the vote I'll have to do some redrawing before painting.
Anyway, the story is about young guy who whores himself out to demons in return for some of their power. In the beginning of the comic he would start completly human, but then as he's fucked by a wave, after wave of demons he'd slowly transform into a sexy demonic dickgirl.
