After months on deployment, months without the ability to fuck. Months without any real privacy to stroke one out. Months of blue balls. Months of unrelenting horniness, it is no longer gay to help out a fellow soldier.  Allowing a fellow grunt to bust a nut in you is a mercy.  There is “no homo” as you get on your knees and start to suck his cock. It is assumed that he will return the favor and help you to drain your balls. 

However, if for the sixth week in a row, you are helping out your buddy and he has still not reciprocated, then you are just his cum dump. A fag who he is using to bust a nut, when there are no women around. He is the man and you are nothing more than a means to an end, a warm hole to jerk off into. Just like back in high school, when you would “help out” the football players, who coach forbid to have sex with girls during the season.
