I love jacking off in front of a gf! I love when they do a sexy tease too while I'm doing it. That stuff makes me explode! My SO used to tell me how impressed she was by the amount and distance of my squirts when I jerked myself off for her.. she said she just loved to watch. That made me feel awesome.
There is nothing like it! My neighbor jacks off all the time. I think he knows that I watch him, but we never talk about it when we see each other. I love it when he arches his back and slowly strokes his hard shaft Some times he plays with his balls and jacks with the other hands. I get wet and play with myself.
