This story was repeated at many parties throughout my college days and always garnered a lot of laughs. At the time, though, it really turned me on thinking about it, although I never shared my opnion with anyone!
My ex-wife (we were married after college) and her best friend would often go swimming in our college pool. One day, as they entered the rather small locker room to change, they ran into two older women (probably in their early to mid 60's) who worked on campus. Being a tiny college of about 1,500 students, they had seen these women many times before but never really conversed with them.
The two older women had just finished showering as they were both walking out of the stalls. My ex was surprised that, instead of wrapping up in towels and walking to their lockers as most everyone else seemed to do, both women were completely nude. Being kind of embarrassed about this, my ex and her friend just said a polite "hello" and walked toward their lockers.
But one of the older women, who worked in the admissions office as a clerk, began conversing with the two of them. Apparently, she had recognized my ex's friend, who had a solo in a chior concert on campus the previous night and wanted to tell her how much she enjoyed her performance. My ex said that the intention behind the conversation was pure, and the woman was as nice as could be, but admitted it was very distracting having her standing two feet away from them while totally naked.
The two of them were, however, impressed by this woman's confidence. As they put it, she had wrinkles everywhere, saggy boobs covered in stretch marks and (this was always the punch line of the story when they told it at parties) a thick patch of silver pubic hair. My ex's friend said the whole time they were talking, she couldn't help staring at the woman's pubic hair because she'd never seen anything like it. Anyway, the woman finally walked back to her locker and my ex and her friend went to the pool.
Being a lover of older women, I was always fascinated by this taking place and my only regret is that I didn't get more details from my ex. I did happen to see the older woman from time to time on camps and always pictured her naked in my mind.
