Considering that I am about 95 straight, who is a 100% anything, I never thought I would answer a Glory Hole question. This may be the only way I would consider using a Glory Hole.
Several years back I was remodeling our master bathroom. Total gut and replace job. My wife was concerned that the job would drag on forever because I am easily distracted by other jobs. I think she bargained with me that I wasn't getting sex until it was done or at least she was trying to enforce that. Amazingly enough the job went fairly smoothly. Some trades I simply sub out, shower pan, tile, those are the hard ones for a bathroom anyway. One of the things I did was install new, matching pre-hung solid core paneled doors for the bathroom and our bedroom. They looked great when everything was finished with the exception of the door hardware for the bathroom door. The exception of the bathroom door hardware was because it was it was back ordered for about 8 weeks. This was by the way not my fault because my wife insisted she wanted that particular style of door hardware, apparently so did everyone else in North America.
When you order a pre-hung door, if you know what you are doing, you order it with the lock set holes pre-bored. So for 8 weeks or thereabouts our stunning new bath sat with a door that had a crotch height hole in the door. A few weeks after I installed the door without a lock my wife was just stepping out of the shower when I was in our bedroom. I could see her through the hole and a thought came to mind. I dropped my pants and my idea had already transmitted down to my cock and I quickly shoved it through the empty lock hole in the door. There was a now a fully hard cock greeting my wife. I said to her through the door, "Hey lady is this a Glory Hole?"
I heard her giggle, she grabbed my cock with both hands, started giving me a hand job and said, "This may be a Glory Hole sailor but I'm no lady and I am going to prove it to you!" For what was maybe the next half hour, who can keep track of time with what was happening to my member, I received the most memorable hand and blow jobs ever. She would ramp me up and then slow me down, I was going nuts. Finally she let me blast my load into her mouth, something she normally is not too into. She had moved back from the door and was leaning against the vanity. That is when I realized that she had only used two hands on me in the beginning. I looked, her thighs and one hand were drenched with her girl juices. She had been working her pussy as furiously as she had my cock. She looked up at me and said that she need to get back in the shower, I joiner her. We dried off and went to bed, exhausted but happy.
Since the lock set for the bathroom door was still on back order we had a few more weeks to use our Glory Hole. None of them equaled our first Glory Hole experience but all were certainly enjoyable. Unfortunately for me the lock set arrived one day via UPS. I managed to extend the time another week and then another week and still had not installed the lock. That Saturday night my wife was in the master bathroom and she stuck her finger through the still empty lock hole giving me a come here motion with her finger and said, "Hey sailor, I'm horny and I have a Glory Hole for you." Like Pavlov's dog my pants hit the floor, my cock got rock hard and I shoved it through the hole. She started stroking me with both hands, her tongue and lips worked my glans, I was breathing heavily, the feeling was wonderful. This was almost as good as the first time; I thought I was going to have an out of body experience. I felt a warm wave of passion roll over me; just as my body was violently yanked up against the door by my cock. My wife had both hands back on my engorged cock; her one leg braced against her side of the door and was literally pulling me through the hole. I couldn't move, she had taken me by surprise; I never realized that woman was so strong or so angry with me. I yelled out in agony; but then it got worse when she moved her one hand down to the corona just above the glans and dug her fingernails into me. Yes she drew blood! I yelled at her, "What the fuck are you doing this is not fun. Oh fuck I just felt something pop, I think you broke it!"
"Okay, now that I have disabled your happy stick do I have your attention?" I moaned back, "Yes, for christsake quit digging you finer nails into me."
"Good, please listen carefully; the Glory Hole is now closed. You do not want to know what will happen to your cock if you stick anything but that lock in this hole again. And you will install that lock tomorrow morning." I was silent, fearing to say anything. I received a sharp tug on my now very bruised and limp penis. I got the hint, " Yes dear I will install it tomorrow morning." Which I did. I was also in pain for several days.
I guess the moral to my experience is; if you find a Glory Hole you can stick it in, but you better know when to stop!
