When I was in junior high, my friend and I would masturbate each other while we spied on his mom, her friends and two sisters as they sun-bathed nude by their pool. We would spy on them from his upstairs room where we could see over the privacy fence.

At first, we just masturbated ourselves. But we eventually found that it felt much better if it was someone else stroking your cock so we started doing the mutual masturbation. We had plenty of time as they were sunbathing for hours. Sometimes we would masturbate each other to multiple ejaculations.

Being young and full of cum, we'd see who could shoot their ejaculate the farthest. We could really shoot some loads!
