I was going to visit my family back home. The flight wasn’t very crowded. About an hour into it, I got up to go to the bathroom to relieve myself. As I approached the back of the plane, I saw one of the stewardesses standing in the galley alone. I could see she had her hand down the front of her skirt. Her eyes met mine, and we both looked away. She took her hand out, and her eyes were looking down at the floor. I got in the lavatory, and I was about to close the door, when she motioned me to wait. She walked over and asked me if I wanted to help her. She got into the lavatory with me and closed the door. It was small and cramped. She rolled her skirt up and pulled down her panties, then she unbuttoned her shirt. She sat on the sink, and masturbated there in front of me. I unzipped my pants and masturbated along with her. She had an orgasm, and when she was done, she had me screw her until we both came. When we were done, she congratulated me on having joined the club.
