I was 17 in 1973 when i pulled into a stripmall parking lot to jerk off. I was far removed from every other car and carefully checked before dropping my pants. No cars came by and i had my finger up my butt while my other hand stroked slowly after i had come on my exposed belly and i never saw the middle aged lady with a bag of groceries approach to ask me a question. I almost had a heart attack and tried bending over but it was hopeless to try to cover up at that point. I said please don't report me. She shook her head, smiled wide and said i comp,etely forgot what i was going to ask you but your dick is cute even though it is not very big.
