I have been reading ST since I was 13, but never contributed. I read the story from the girl who masturbated in an organ loft and something she said made me want to go further.
I too am an organ scholar. I won't say where I am learning, but the organ, like the other one is very old and you get to the console by walking through the instrument. There are pipes on every side. Our tuner says this is one of the easiest organs to tune as a staircase and series of galleries runs through it and he can get to any of the ranks of pipes with no ladders or anything like that.
Ok, first, a bit about me. I have been jilling, (mostly with the help of ST) since I was 13. I cum in a very physical way. After a couple of good cums, my tummy muscles actually ache because they contract so much you can actually see it.
So, I got the idea from the contributor who wondered about jilling off with an organ pipe. The thought stuck with me for a few days and then I thought about actually doing it. So I walked up to one of the highest galleries, (partly for privacy as I don't have keys to the organ case). Up there is a rank of pipes that are tapered at both ends. The foot of the pipe is smooth and shiny and, well, I figured just about right. I was already turned on by the time I got there, so I slipped my knickers off and chose a pipe I thought would be about right.
First, some attention to my clit to really get me going and then a nice little fantasy. (In my case, I really like the thought of being laid by one of the choirboys and initiating him.) So at the appropriate moment, I pushed the organ pipe gently inside. It felt cold, but oh, so hard. Also, the fact that it was hollow; open, felt kinky too.
Then, my orgasm started to build really fast. I edged for quite a while before finally letting it happen.
Then I heard it. A regular PEEEP PEEEP PEEEP.
As my pussy contracts, I usually suck in and expel air. (Unfortuantely, I fanny-fart terribly) Except this time, there was just enough expelled air to make the organ pipe I had in me actually sound. When I realised what it was I started to laugh uncontrollably. Here I was, fucking myself with an organ pipe and my pussy was contracting enough to make it sound. The tears were rolling down my face and I just could NOT stop laughing. In fact, I laughed so much, I actually wet myself.
As an erotic experience, I learned two things. Masturbating in unusual places, (and they don't come much more unusual than inside a 250 year old organ) is one thing, and something I will definately be doing more of, but using an organ pipe... er... no. BIG mistake.
Still, life is an adventure and you live and learn, I guess.
One interesting aside is that during my lesson, as I was playing, the organ teacher said 'Hmmm. that upper C Gemshorn needs tuning.' (I hope I didn't blush TOO much.)
