Th most unusual place was in the 15th row of a United 747 returning from Hawaii. It was about 2 AM, the flight wan't crowded and the girl I was with wanted to join the mile high club. We had 4 seats to ourselves so no one was in a direct line of site and the cabin lights were dimmed. She went to the bathroom and removed her pantyhose and panties. We climbed under a blanket and spooned. Nice and quiet. We both came as quietly as we could. Afterwards when we got ourselves together we though we were a cool as could be until it dawned on me that the air around us reeked of sex!!!! Anyone who was awake had to know what we were up to. Fortunately the plane arrived in Chicago at 5:00 AM and all everyone wanted to do was get off the plane and get coffee. I will never forget this lesson - Sex smells - It may smell great but boy is it strong.
