This story occurred several years ago when my wife and I had taken our 21 year old daughter on a dive trip as a graduation present in the Bahamas on a live aboard dive boat. My wife is a n attractive 50 year old of germanic descent with a great athletic body and in superb shape. The boat we were on had an upper and lower deck area where most of the cabins were in the upper part with 2 cabins on the lower deck, one of which was occupied by the very good looking black dive master. As the cabins had 2 bunks only my wife and daughter took an upper level cabin and I got the lower level cabin as all the others were occupied by couples. My wife and I had enjoyed a discreet sex life with other partners in which we were aware of each of the others affairs and found they enhanced our own sex lives in distinction to many of our friends. Most could not distinguish between recreational sex and serious involvement and as a result their affairs led to divorce, dysfunctional families and financial hardships.
At the end of a day when we had done 3 dives and where at a decompression stop at about 20 ft beneath the boat where there was a safety air tank and regulator my wife’s dive computer began flashing for her to descend. This occurs when the total accumulation of nitrogen during the day exceeds the dive tables safety factor and requires a longer decompression at depth. It just so happened that the dive master was at this stop, saw my wife’s computer and as she was nearly out of air grabbed the safety tank and descended to a depth were she could safely decompress breathing from the accessory tank carried by the dive master and after about 20 minutes or so they surfaced.
