I always suspected that she was cheating on him but I never expected to catch her virtually in the act. My roommate Dan and I had been in the Army for just a couple of years and were at our first duty station on Fort Bragg, NC. His girlfriend Amy had moved in with us just a couple of months before Dan deployed for 6 months and she wasted very little time becoming a fixture in the area party scene. Several times she "stayed over with girl friends" after going out but I was pretty sure she was finding a little love on the side. There is never a shortage of horny young men on any US military installation. So when I entered our apartment in the middle of the night a day before our field exercise was scheduled to conclude I walked in on Amy's hook up taking a piss in the bathroom we shared. He was a nice enough guy and when asked freely admitted that he had come back with Amy and was enjoying her company. I went to bed.
The next morning the dude was gone and uncharacteristically Amy was up and waiting for me as I came in to make some coffee at 5am.
"It's not what you think Bill." She said.
"Save it Amy." I replied. "The guy told me you two were fucking and frankly I don't think for a second it is the first time since Dan left. You can't keep your pants on and that is all there is to it."
Amy looked down but did not attempt to argue. "Are you going to tell Dan?" She asked.
"Hell yes I am going to tell him." I shot back. "The dumbass loves you and deserves to know. I sure would want to know if my girlfriend had another guy in my bed before the door hit me in the back."
"Bill, I am begging you. Please don't tell him. I promise that I won't do it again. I will stop drinking. I will do anything." She stammered as she began to get choked up.
"Crying is not going to work on me Amy." I replied as I walked past her and out of the room.
I went in to the Company armory where my men were cleaning weapons and spent the rest of the day thinking about whether I really should tell Dan. I never really liked Amy and she did not deserve a guy like Dan. He had fallen for her dark hair and brown eyes the first night they met. It should have been his first clue that she went home with him and sucked and fucked him all night long. I had really enjoyed the stories Dan would tell about her before they got serious. Amy had great curves with full D-cup bosoms and a strong athletic build. She had dark hair and brown eyes and stood about 5 feet 8 inches tall and probably weighed close to 150 pounds. She was not fat but muscular and according to Dan she loved cock. He said she loved to suck it and loved to fuck it. He rarely slept the first 3 months they knew each other.
After we dismissed the Company for a long weekend I went to a local bar with some Army buddies and knocked back a few beers. I was pretty tired from being in the field all week and as I began to enjoy my buzz I decided that I would see how far Amy would go to keep our little secret.
