Want To Try This Glory Hole In Town But Scared

There is this place in town that I've heard has glory holes. It's a sex shop. The only problem is that it's located on a very busy street. Probably the busiest in town and there is a traffic light about 50 feet from it so whenever traffic stops, they can just look at it. I really want to go but I'm nervous for people to see me walking in or parking in front. There really isn't parking where your hiding much. I think it closes at 6 or 7 pm. It's called the Book Ranch in Fort Collins Colorado if anyone wants to check it out. I'm not looking to get my dick sucked. I really want to give a blowjob. I've never really done it before but I get so horny thinking about it.
