With wife helping and watching.

When I was around 15, we lived behind a used car dealership. It was very easy to climb up on my wooden shed, then hop over to a shed in the dealership lot, then hop down on a car that was parked next to the shed. (they packed the cars in tight in the back lot behind my house) They left the cass back there unlocked, since they were packed in behind other cars, and a fence.

Late at night, I'd sneak over there, trying to be quiet, Then climb into a car, and jerk off. The best part was it was private and I could shoot my cum without having to clean up, like in my room. That whole summer, I must have cum in around 50 different cars. My favorite was a big LTD. that backseat was so big, it was really comfortable. I spent hours in there at a time, just jerking and cumming. When the backseat got a little too funky, I sat in the front. It had a power seat that worked without the key, so that was great. besides the steering wheel and dash, a couple times I even hit the windshield.
I cum heavy, so in short order that car got really smelly. sitting in the sun must have done it.

I blew it rigth before school started. during a game of chase, they saw me run over into there, and followed me. they really dented in the hood and roof of the car next to the shed, so it was obvious what was happening. they went in there a couple more time, and would even run around on the roofs of the cars chasing each other. I'm sure the owner figured it out, because they installed big lights on a pole in the back, and i imagined maybe even a camera. My jack off spot was ruined for good.

anywhere & everywhere

Why? Are you ashamed to be masturbating? It's normal to masturbate but it seems odd that you feel a need to slink off to the downstairs bathroom or to the basement to jack off. Why not surprise her in the shower with a beautiful boner? Perhaps the surprise and excitement will encourage her to give you a 'helping hand'.......

I like to jack off in private sometimes too
