I think I've posted a list on here before, but there's definitely some updates to add
Obviously, I've masturbated in every room of my house, plus the attic, which is basically just storage space with no proper floor - just spaced out boards to walk on.
I was sat on a chest full of books after doing some tidying around up there. The adrenaline from having just carted about a load of heavy stuff and worked up there in the heat for an hour got me horny ... and when my dick calls, I don't ever refuse.
Since the last time I posted about this, I've also masturbated to orgasm 3 times while driving. Each time has been on a motorway, at 70mph.
They've been after a weekend visiting a friend. I've got into the car for the 3 hour drive home, wearing sweat pants. Then, while driving, pushed the pants down, to expose my cock and stroked. I don't know for sure that people have seen what I was doing, but I didn't do anything to hide it when they were passing me! To make for a quick clean up, I've slipped a sock onto my cock for when I came. It's nowhere near as dangerous as you'd think, especially on the motorway where the traffic is all one direction and going at roughly the same speed.
Workplaces. My current workplace is a pretty large office building. I've masturbated in every cubicle in the 4 toilets on my floor - and am working on the next floor up. It's good to have goals at work.
Previous workplaces - I used to be a security guard when just out of university. I didn't have a regular building to guard though. I was always filling in for people on holidays ... and almost always on night shifts. I used to seek out good places to stroke - and good places to cum - in all of the buildings. A couple of my favourites:
One place, I'd worked a lot of days there too and had become acquainted with a really cute girl there. She was just 20 and looked awesome in her librarian-style smart casual clothes. Well, I knew where her desk was in the building. So, when working nights there, I'd go to her desk, smell her chair, then sit in it and stroke. But I never left any cum at the scene
One place, I'd have to change the tapes for the security cameras at midnight. So, during the time when the last day's tapes were rewinding (this wasn't actually that long ago, but these companies use crappy old systems until they fall apart), I'd go right out into the middle of the reception area and jerk off where the cameras would have seen me, if they were recording.
And one place, a really tall office block, I used to go to the very top of the stairwell, kneel down at the railings on the top floor point my cock through and stroke til I came - watching the cum shoot off into the stairwell, and fall 10 stories to the floor. Always turned me on, for some reason.
Whenever I stay over at a friends house, I always make a point of masturbating in their guest room and bathroom. Like I say, if the opportunity arises, I'm not going to deny myself! I've had orgasms in a dozen friends houses over the years.
Finally, here's a list of the countries that I've cum in (no particular order)
United States - Illinois, Texas, Florida, Pennsylvania, New York, California.
Mexico
Brazil
France
UK - England, Wales, Scotland, Ireland
Republic of Ireland

I think that's them all.
