I'm not sure of her name, but she's just about the hottest one in a video I have called "Busty Beauties of the '70s" from the Mammary Lane series, I think.
And I can guess what happened to our wet t-shirt redhead, too. I bet she was the mousy, smart girl that nobody paid attention to, but as soon as she had too much to drink and took her top off, she became Miss Popular. Moral: Always give that mousy, smart girl a second look. Worked for me.
