In several of the Japan tickling videos they have the girl tied to what looks like a smaller version of a socker goal just without the net?

I was looking for something portable or at least something that I can take appart and hide when family comes over.
I want something that when my wife is on her back I can tie her legs spread and up in the air. Looking for that helpless but comfortable device that I can tickle,have sex,oral pretty much whatever I choose.
