Best friends, Ryeowook and Sungmin, discover that neither of them knows very much about the male anatomy – with the exception of bad diagrams and crude ideas instilled in them by friends. Sungmin, in all her brilliance and daring ways, decides that enough is enough and the fountain of knowledge must be sought. The two find it in the bathroom at the end of the hall – where Ryeowook’s stepfather is taking a shower.

Note: This is a GENDERSWITCH fic; it is also made up entirely of dialogue. There are only two people talking so there should be little confusion.
