An Unexpected Encounter at Basic Training

Summer 1986... Ft. Jackson, SC... While awaiting assignment to a basic training company, myself and several other enlistees were selected for a detail cleaning the post's momentarily vacant drill sergeant academy building. Each of us was assigned to a room with instructions to clean out any discarded items in wall lockers and desks, before cleaning the room itself.
As I began filling a trash bag with scraps of paper, cigarette butts or the occasional nip bottle, I found one wall locker contained a box of dirty magazines and not just the usual Playboy or Penthouse, but a few hardcore gay mags.
At this time, I had only had some early teen playing around with a friend, mimicking action found in similar magazines belonging to our shared landlord. As I looked at the images of the man on man action, I could feel my dick starting to get hard.
First checking the hallway, I ducked into the bathroom, sat down and began to tug on my growing dick, remembering my old experiences.
Leaning back, eyes closed, as I let my hand work up and down my shaft and over the head, I was shocked to hear someone clear their throat and stop my self groping - opening my eyes, I was greeted by the sight of the sergeants who had assigned me to the room.
Totally embarrassed, clutching
my dick and expecting to hear a profanity filled tirade straight out of the movies, I was shocked again when his quiet response was simply: "Don't usually see a private making himself so comfortable... don't stop."
I don't know how long I sat processing what he'd actually said, but it was long enough for him to repeat- with a stern tone: " I said: 'Don't stop... PRIVATE'".
Slowly, I returned to working my cock, looking at the sergeant as he began to rub his own dick through his camouflage fatigue pants. Thinking my time in the army was over before it had even begun, I couldn't believe I was sitting jerking my dick while the sergeant began to reveal his own.
Watching as he worked to stiffen his dick, he stepped forward and placed the tip of his dick just inches away from my mouth.
"Well...?" was all I needed to hear before slipping my mouth over the thick head, feeling it slide over my tongue and back into my throat.
Slowly he began to work his hips back and forth, humping my mouth as I continued to jerk my own dick.
I began to feel the sergeant's precum filling my mouth, even as my own began lubricating my continued masturbation.
Moments later, I had to stop as I started to shoot what felt like the biggest load of my life, feeling it jet from my pulsing dick. Seeing me cum must have been the trigger the sergeant needed, plunging his own dick deep into my throat and unleashing what was a truly big load.
Eagerly I swallowed as much as I could, even gagging once or twice and earning a quick "Ssshhh, private. " from the sergeant. With the last pump, he pulled his dick from my mouth and rubbed it around my lips, letting me lick up every tasty bit of his load - the first I'd ever tasted other than my own. Adding another surprise, the sergeant then leaned in and began to kiss me, sharing his own load of warm cum.
"Really good job, private." he said nect telling me to hurry up and finish cleaning the rest of the room, before tucking in and heading back to the door and out into the hallway.
While washing myself up, I began to think this had to be not only the luckiest day of my life, but truly the most surprising.
The final surprise would come two days later, when arriving at my training company barracks, and finding that my drill sergeant would be none other than a familiar face - among other things... lol.
