Saw my parents

Many years ago when I was 18m and getting ready to head off to college I came home early from work. At the time my parents were separated and my dad was living in a trailer behind our house. I needed to ask him a question so I just open the door. My mom was riding my dad right there on the couch. She was a bigger woman with massive tits. I saw everything for a very short period but is a fond memory. Afterwards I went to the side window and continued to watch them. Just a great memory. They are now in their 60s and she still has great big tits.
