I grew up seeing her semi nude and a few times nude. As time went by I would dress in less and less and sometimes she saw me naked. After so many years, we went fishing and she actually took pics of me wearing the most revealing underwear - what the heck is going through her mind? It looks as though I'm almost hard even thought I can't remember how it felt at the time... are there any females who would be able to figure out what she might be thinking?
