Plasticbag and automatic handcuffs

[rubbnoair]

Hello, I'll handcuff his hands behind his back after spending a plastic bag over my head. They are handcuffs that open automatically after an adjustable time.
The question: How long should I set the aperture handcuffs knowing that I would head in a plastic bag like my profile picture??

I do like being bagged, the panic is very excing
