When my wife and kids are out of town or even when they're asleep at night, I often spend my free time checking out hot sites like Solo Touch, and generally getting myself hard and horny. During good weather late at night, I often end up outside to shoot my load. Our backyard has a small deck, and a large area of grass, and while the fence is chain link, it is somewhat private because of the trees and bushes on three sides of the property. Nevertheless, I don't try to go out there when no one can see me. What I try to do is to turn on maybe a light or two inside the house so that someone looking out their window thinks they see 'something,' but they really can't see clearly enough to know what or who.
I was outside last night, and when I first got on the grass, it was too dark, and I thought 'what's the point?' So I moved toward where a little bit of light from the kitchen spilled over into the grass, and dropped by boxers to let out the tension. I had been watching mini videos on the computer, so I was ready after a few good strokes and came. A couple of times, I've laid down on a towel in the yard and shot my load on my stomach, then rubbed my cum into my skin.
So far, I've never had any indication that anyone has seen me (or cared to see me) in the yard, but the prospect and the heightened sensuality of being outside always makes for a good cum.
