Right now I only really have one toy as my other didn't work for me so I gave it to a friend.
I keep my lonely toy in her box (she's a lelo) and keep it in my underwear drawer, which is in a dresser opposite the end of my bed. Sometimes I keep the box out on one of my night stands, depending on who's around really.
Mine is not hidden, but in my dresser. It has a very thin shelf on the top that runs the length of it. Just deep enough to keep my toys in, but wasn't enough to keep my lingerie in. Most people assume it's for lingerie though, so leave it alone (I have a couple friends who wear the same size in clothes and borrow clothes fairly often).
I've always wondered where it is that people hide their naughty toys and other things. Where do you hide them?
The bottom drawer of my desk, in my bedroom. I used to keep them in a box under my bed, but with young children, I needed a better hiding spot. At their age, all boxes are practically begging to be opened, and I wouldn't want them dragging out my toys when my step-mom and dad were over (which is exactly what would happen-- LOL).
We don't really hide them, but we do have a storage box we keep them in most of the time. They are almost always in the bedroom in their box, but not really hidden. Having them all together in one box makes the selection process easier and more fun. (Close your eyes now Honey. BZZZZZZZ OH MY!)
