This is not my embarrassing moment but so funny I thought to post it here.
I'm divorced and live in a garage apartment in a stately home. The neighborhood
is rather upscale. Two houses across the street one day while walking in the early
evening on a Friday, I noticed moving images on one of he picture windows. It was of what
looked like amateur porn. I watched for a time then kept walking but went home
and masturbated as the images were very erotic.

There was a woman being double-penetrated, one sucking two large cocks at the
same time, a woman between two men, one in her mouth, etc. In one scene a man
pulled out from doggy style and shot his sperm over the woman into her hair, and
further out.

One man and woman were very familiar to me. I realized it was neighbors I did not
know but greeted on the streets and nearby shopping.

One week later, on my evening walk, there were images again. This time, someone else
was driving by and stopped, noticing me on the sidewalk watching. They said, "Is this
a public showing?" I shrugged my shoulders and kept walking.

This went on for several weeks. One day, my curiosity killing me, I knocked on the
door of the house and asked about their porn display on Fridays. The lady was
flushed beet red and said, "What, Oh MY GOD". It seems that she and her husband
were swingers, had taken videos of their activities and then showed them to their co-conspirators.

They had put a sheet up on the picture window and projected the videos using
the sheet as a screen not realizing that the images showed up clearly on the other
side of he sheet and to the outside world.

That was the end of the public porn show but at least I feel I somehow helped
these people stay out of jail or something worse
