Well that would be a bonus on both counts at least. We can regularly hear our neighbours going at it and while we are happy they also have an active sex life it can be pretty off putting when you can hear it when you are trying to be intimate
As in the kind from toilet vending machines? Harder things to explain than a spreader bar?
That is quite expensive for a sex toy storage box but guess it depends how out there the collection is and how much embarrassment it could save.
I had a friend who on a whim bought a sex swing and took ages for them to find a time for them to use it. One afternoon while kids were at the in laws they managed session and then went out.
When they got home they saw his mother in law had brought kids back early and when they walked in house they were horrified to find they had forgotten to put the swing away and she was attempting to put one of the kids in it thinking it was a baby bouncer or something.
