My wife (then girlfriend) and I were returning from meeting her parents for the first time. For the trip home, her mother had packed some snacks for us including a 2 liter bottle of Dr. Pepper. While flying over southern Georgia, I asked my her to pour us a soft drink. When she held the bottle between her legs and unscrewed the cap, the soft drink spewed, soaking her all over. (Un-pressurized cockpit) I suggested that she change clothes.
She proceeded to strip naked and then reach into the back seat for her suitcase. Since I had the autopilot engaged, I immediately started fondling her cute, naked behind. Well this gave her ideas, and she started helping me get out of mine. She then proceeded to sit in my lap facing me.
After we were through, we collected ourselves long enough to get dressed and land in Athens, Ga. for fuel and a rest break. After departing, we had to go again.
Every time I have a Dr. Pepper, I have to smile :-).
