I've posted elsewhere about our fun with the wheel - but the whipping bench got several uses, combined with the fucking machine. Great fun.
We also used the swing - Mistress seemed to enjoy the ability to winch my head and feet to differing positions.
We ran out of time to try some of the other 'big ticket' items - but we're going to go back at some point to give them a go. On my list are the stretching bench (rack?) and gynae chair. We'd also wanted to put me in the cage or the isolation (coffin?) box*. There was also a chair which could have a dildo attached - but we couldn't find the right dildo. Being strapped into the chair with that in place sounds fun.
All these things take time to enjoy. Other than a bit of play at home, our recent visit was our first time with more serious bondage/equipment. I loved it, but it did make me realise that much of the play (for us) is building up the suspense (no pun intended!) and the sense of captivity - and that takes time. I'm sure being strapped to a piece of equipment for an hour or more is very different to just a 10-15 min stint.
* Must get a cage or box at home one day - would be fun to be secretly locked in that while Mistress had guests round the house
