You realize that if you have a willing whore, you can make a gloryhole anywhere the hell you want. Hell, just ask someone to make you a gloryhole, and they'll make it for you. You're the one supplying the slut after all.
Post a craigslist ad in the W4MM section saying "don't know where a nearby gloryhole is... can someone make one or tell me where the local one is for my whore to suck you off at?"
You'll get 100 replies in the first hour, because random strangers love having their dicks sucked.
