When I was about 16 my friend and I went to ride our bicycles around town. We were cruising on the side of a street that bordered a residential area. Between the street and the houses there was a sort of a small park with a few trees and very few bushes (this is important). So we are passing through a crossing, and I take a look around to see if there are any cars approaching us. It was then when I saw an old lady in typical old lady clothing standing bent over in this park, not far from the houses. She had put her hands on her knees as if to support herself, you can see runners do the same thing when they finish an exhausting route. We move along and I, perplexed with her posture, forego road safety and continue looking at her while my friend rides beside me, blissfully unaware. We ride past her and now I’m looking at her from behind only to witness a yuge pasty-white sstrememly sstremely flabby old lady ass with old lady clothing (skirt or whatever, I can’t recall) pulled down barely enough to reveal that this ass is in the process of expelling what I can only desrcibe as a very solid-looking chocolate log the size of my teenage cooming forearm, both length and diameter. I immediately put my eyes on the road and gained speed. I never told my friend what I saw. The mental images haunt me to this day.
