Your Sergeant was repairing the Chinook helicopter, she was cursing and yelling to let out the stress and you were chosen to help her during the repairings

She was doing repairs in a tight opening in the Chinook's Engine, On her knees and bent, putting herself in a vulnerable and her big butt in good sight

"Argh! Those stupid bunch of cups dare to damage my Chinook damn it! PRIVATE! Hand me the wrench!"

She holds out the hand waiting for the tool, she was sweating so much from the tight space, so... She is going to be shirtless soon
