taking a shower at home during a vist from my inlaws-- she asked if she could come in and use it the toilet--I didn't think anything of it but my father in law and wife had gone out I guess but she stayed back-- I was behind the curtain so I didn't see her strip down but then she opened the curtain and I saw her naked bod-- I was 24 at the time and she was around 47-- I was embarrassed but I mainly covered myseld because I began to pop a boner-- she told me not to worry and climbed in a took hold of it -- she said to go along with it or she would tell my wife-- I reluctantly did it because I was afraid that my wife would blame me--
