Sargents personnel aid

After my first encounter with the barracks duty Sargent I became his assistant (the one under the desk). There was a good reason for his big balls(the size of tennis balls), he demanded constant attention shoving my head down between his legs. I became really well versed knowing what I would be doing several times a day, under his desk polishing his equipment that hang between those big legs. I knew when he walked over to lock the door to his office that he would be ready for me to assume the position. The strange thing about it I really began to enjoy my chore of draining those big balls dry sucking till I drained every last drop. He would tease me pulling it from my sucking lips asking if I was ready for more cock milk? Sometimes I would lick the massive head and shaft like an all day sucker before getting into sucking him off. As this became a daily task his balls seemed to be getting larger and his loads as well? I walked in one morning ready to suck my first big load and he told me that he had been reassigned and another Sargent would be taking over. He said he told him of our special arrangement smiling saying he thought that I wouldn't object as he introduced his replacement another big black whom I had heard rumors of being hung like a horse? Well it didn't take long to find out as he ordered me to my knees and dropped it out slow stroking it to full attention asking me if I liked what I saw moving up to place the big head to my lips. He said I think you know what to do with this cock don't you, cock sucker. This thing was so large I really had to work just inhale the massive head, being met with a taste of precum as he began to call me cock sucker I began to start working over this massive black cock, he said looking down, come on bitch drain my balls like a good white bitch! I could see those massive balls begin to tighten knowing all that sweet black ball milk was about to reward me. WOW it started about blasting it seemed out the back of my head faster than my mouth could contain spilling down all over, it seemed like his cock milk would never stop flowing. He looked down and said I think you will do, he thanked the Sargent who had been feeding me for several weeks and said you did a good job of training this bitch I'll keep him fed for you! Now you, back to it suck some more of my black juice out you aren't done till you milk me dry. Laughing and rubbing the big head across my lips....
