Yeah those definitely do it for me.
Even the waiting works for me.

I did some sessions before these retrained objectification ones and found that I was easily pulled out of sub-space by interaction.

In the Party Sessions the Domme doing the rigging gave me, barely, access to an air horn (LOL) to only be used in emergencies if I couldn't talk or breath because of the realities of the situation. If you want to feel like you're drowning in piss, you probably don't want to actually drown in piss. Breath Control, Extreme Sensory Overload, Ignore Fetish. I'm even wondering what it would be like with Auditory and Visual Cut off for a more pure two senses experience. Probably too much.
