Thanks to those with kind comments. There had been a scene one night at a large connecting airport. Bill and I had been returning from a vacation in the Caribbean. Due to weather problems our flight had been delayed and we were waiting for a later connecting flight. The airport was big with many wings and sections. Our waiting area was a small one. As it had been well before flight time and I guess in light of the weather with flights cancelled, it had been pretty much deserted.
I had been idly rubbing Bills thigh when he had said that it had given him a serious hard on. He asked if I'd jerk him off. I agreed and had unzipped his cock. I looked around the room and aside from a young man two rows over slumped in a seat, there had been no one around. I teased Bill with a slow jerk off that only made him more in need. Eventually I had undone my own slacks and had one hand in my panties, fingering myself as well. Bill had one arm around me clasping my breast and finding a nipple as he did. We kissed and had gotten lost in the moment. Bill got harder and I had quickened the pace until he was shooting arcs of cum into the air and onto the floor. I then folded his cock back into his pants and focused on my own pleasure. Bill raised a hand under my blouse and kissed my neck, knowing that drives me crazy. I spread my legs a bit, lowered my slacks slightly and began to seriously frig myself to get off before anyone showed up.
As I looked around I noticed that the young man had become awake and had been staring at me. In fact, though I had not told Bill, I could see that he had his cock out of his pants and was furiously jerking off. I wasn't sure if I had been shocked or flattered. My clit responded as the thought of my being watched by this horny young man had made me even more excited. I slipped my slacks still lower so that he could see my fingers at work, the thought of which had made me start to come and come. I tossed my head back and forth and came more loudly than normal. I could see my young observer do the same with one spurt over his hand. I quickly got myself zipped up just before some people had arrived for the flight. Our young observer had gone back to sleep ... or at least so it had looked. Bill and I both slept through the entire flight.
