Tied up with a Venus 2000 milking machine?

Hi, I'm Marten 22 from Bakersfield, I'm new here I hope it's ok to ask a question like this.

I've been fantasizing about being tied up with a milking machine for a long time, and having multiple orgasms, I have the option of borrowing one of these, as they are very expensive, but I don't have anyone I trust enough to do this to me, I've seen that you can order a kind of holder on the website to attach the device to the balls so that it can't fall off or anything like that.

But since it's difficult for me to tie myself up when I'm alone, I was thinking of a kind of time lock that opens again after an hour alone, for example.

do you think this is safe or rather dangerous? i don't know what kind of speed etc. to set, does anyone here have experience and can help me a bit?

Please play safely with this and make sure you have got a plan when you are playing with things like that alone.
