Hampshire here. Work in London and used to live there, but its really not compatible with a family, unless you're a banker (which itself isn't that compatible with a family).
I love it. I would live down there if I could. And for me its not just the pussy. Its the whole experience. I like tonguing my wife's anus, and, not saying I'm into water sports at all, but a small tinge of urine can be a very surprising tangy bonus to the occasion. Its all about the touch and taste sensation for me. Actually, I find it easier to cum from a 69 than a blow job, strangely enough.
One handed is easy. I have actually managed it with a foot before. Accidentally.
Yes, in the bathroom at work. Its more of a thrill in the disabled toilet as I'm only one door away from everyone seeing me, and I would be directly facing the main entrance to the bathroom facilities!
That said, I have once wanked art my desk in a part time job a long time ago. I got sent to another office as our computers were down, and I found a stash of gentleman's magazines in one of the drawers. I was three only one in the room for the day, and want regularly bothered. Everyone else in the building was female and a total stranger that I would never see again. So I knocked one out at my desk, cumming in my trousers. A very very weird way to spend the rest of the afternoon.
Yes, bathroom. The fear of getting caught its the best bit. Apart from my previous masturbation addiction. For some reason, its all the more 'fun'in the disabled toilet -two disabled stalls on every floor, but 6 normal gents ones. But they're straight ahead of the main bathroom corridor -there its just a door separating me from everyone seeing!
