Well just to update things for all:
Yes, she did find the stash while her & my wife were doing something on the computer. I was out for the day but when I got home, the 2 of them had their tops off and were making out while watching some video clip. They asked me why I took so long to come home and yada yada yada...
Then I woke up.
She left yesterday and I doubt she found anything. Well if she did, she didn't say anything about it. A part of me is hoping she did see it, she's very hot and 21. Hehe.
Thanks again, guys & gals.
