A One-Time Thing
I was walking my dog on a dirt road next to my subdivision. This dirt road ran parallel to several backyards and had lots of trees on either side for concealment.
For me, it was an unofficial nature trail because it allowed me to get away from people. One morning I spotted two of my neighbors, who were married to other people, making out and obviously about to do the deed.
Since they were so into each other they didn’t hear me coming up till my dog started making noise. For several seconds, we all looked at each other without saying anything until the couple took off running in the direction of their respective backyards. We all knew each other but I wasn’t friends with the two nor their spouses.
Long story short, I kept my mouth shut about what I saw and neither of the lovebirds ever said anything to me. Have no idea if this had been a one-time thing or a long-term affair.
