Hey! Vietnam vet here too. Myself and best buddy were on a listening post one night together. I was awake and my buddy as sleeping. I decided to jerk off from boredom. I got my cock hard and was enjoying myself, when my budds stood beside me, saying he couldn't sleep, either and enjoyed watching me. I told him to join me, and he did. He had a beautiful cock, and I asked him if I could suck it. He quickly agreed, and I dropped to my knees, taking that hard cock into my mouth. He didn't last, and pumped his load into my mouth. I swallowed and kept sucking. I drained his cock. Next, without a word, he sucked my cock. I shot quickly too. It was beautiful... We continued sucking each other thru our whole tour. In the shower, in the bush, every chance we could find.
