Go to squirt.org and under the head Cruising, type in North Carolina. There you'll find a multitude of adult places to have fun which could be an hour or more drive from where you live. The site is free, but you'll be limited to what you can access which is why a membership is the way to go. Have fun!

In North Carolina they probably are indeed hard to find. Here in San Francisco they're all over.

Glory hole sex is indeed the ultimate in anonymous sex. You don't know the man you're sucking and you cannot even see him except for his dick. All you know about him is that he wants to be sucked off. All he knows about you is that you want to suck him off. It's pure sex, sex for no other reason than to have sex. And that's all that matters. The mouth/dick connection becomes the center of the universe as everything else just falls away.

So good luck in finding a glory hole and sucking a guy off thru one. It's fun.
