One is the cross on the back of his neck. And then...there's the other one. XD
I posted the actual art for it earlier, but here's where it is. And... I just figured that if anyone would wear jaguar-print underwear, it's /so/ Yuri.
A sketch, this was originally stuffed in my Scraps folder. But enough people have told me they like it, I've moved it into my regular gallery.
Absentminded note: no, I had no figure reference for this; it's just my own daydreaming. (Why...NO... I don't spend a lot of time thinking about Yuri's ass, I SWEAR....)
