OK, this isn't exactly what you had in mind, but it is an idea...

My partner and I think this has lots of possibilities, but we haven't gotten it yet.

While a custom piece of furniture would be cool, this wouldn't certainly be more vesatile, as you could use it on other pieces of furniture, and use many different kinds/style of dildos and vibes.

Hope that helps.
