Picture Exchange Monday (PEM). The never-ending weekly ritual where girls get together and drink too much wine and then fiendishly take sexy pictures of themselves together - pictures which will then be exchanged in the same meeting place the following Monday, and the next Monday, and so on. It is not uncommon for previously "straight" girls to realize that they are truly lesbians after participating in PEM.
Andi and Chelsi look forward to PEM all week long. They can't get enough of their weekly love fest.
