Something similar happened to me at UBC beach about nine years ago. I was sitting there on my towel when an enormously stacked girl in cornrows and wearing a denim dress sat down next to me. She reached under her dress and pulled off her huge biege bra. She then pulled a bikini top out of her bag and clumsily put it on under her dress. I remember thinking how silly she was to avoid showing her tits, even for a second, since that beach is clothes optional. She finally took off her dress, and damn! it was worth the wait. The top was very tight on her and plumped out her breasts very nicely. After about half an hour, I could take no more and ambled to the washroom and took care of things.
