Shithole-licking, the closest we can get to sheer bliss without actually cumming

We've all know guys who get so excited by tongue on their shithole that even without touching they can't hold back from shooting, but that's okay as well, especially if you know by his warning you that it's about to spurt and you can get your lips round his cock before first shot. If you miss it then you've got to lick it up while it's still warm, which is fine as well.
