Is it normal if wife's sis mentions to have seen our nude pics?
I have a good collection of nude pics of myself and wife, which we keep in computer, as well as got their prints. The prints are kept in safe custody. Once my young and virgin sister in law (wife's sis) while visiting us advised me to keep our nude pics in safe place. I was surprised, rather shocked, how did she know it? I thought perhaps my wife had herself shown her these pics. Next day I asked sil if pics were shown by her sis? She said NO, but didn't tell how did she see. My wife seemed to be ignorant as her reaction was normal, even we took more such pics. I still don't know why my sil instead of talking or advising her sis (my wife) preferred to mention it to me. Any view please.
