Jakob is usually reserved and relatively sensible in his mode of dress, but at the end of the day he is an incubus and has affinities for fear and lust. Hence there are times when he'll occasionally go a little weird and, say, lounge around seductively in a fetching latex outfit. Even a 1000-year old Creature needs a good lay once in a while, after all. It's always the quiet ones, as they say.

This is another PWYW sketch done by - I inked it, coloured it and redid the muzzle a bit. Originally it looked like he had a Hitler moustache which was Not Good.

The original sketch is here: http://www.furaffinity.net/view/18601684/

I also have a version where his, uh, package is a bit less bulgy, and I may post that after Christmas when I get home so that folks who have blocked the mature/adult artwork can also see Jakob in all his dodgy glory.
It's not like his crotch is that well-defined anyway, if it was you'd be able to see that he has humanoid bits rather than a sheath, but I figure it probably crosses the line for General so here we are.

Happy Christmas!
