My daughter often called her ex-husband to meet her at a sizable airport several hours away to drive her from the airport to my home. She and her ex-husband still enjoyed fucking each other, even though they were re-married to other spouses. Her ex-husband told his wife he was staying at his parents’ home, who lived in the town where I lived.
Unknown to anyone (including my daughter), he and I had been lovers before he married my daughter, before and during their courtship, and during their 3-year marriage. We managed to enjoy each other at least once a week during his last year of high school. He was 17, and I was 43. After he went to college, we continued to fuck whenever he was in town, at my office, at my home, in a car, at a riverside cemetery.
So, when he dropped my daughter (his ex-wife after 1971), we managed to meet before he drove back to his home. I remain addicted to him, as a once or twice a year lover.
