During the first Gulf War, 8 of us shared a tent and opportunities to j/o were nil. So, we came up with a system one of us played sentry outside while the rest of us stood in a circle and jacked off on a magazine or just watching each other. I must admit the sight and smell of hot cum spraying out of 6 of your closest buds' cock heads and spilling out onto the desert was pretty hot. The last guy to lose his load always had to clean up and play sentry the next time. We had a few of these sessions right out in the open desert!
