I know the text prompts to get Samantha to "fuck the machine" and "get in the cage" but what about to get her back into the original restraints/bondage she appeared?

Samantha keeps asking for the fuck machine to vibrate. Is that an option I'm not seeing?
Also can you not tell her to get on the bed. When I told her to do so, she did not (?).

For me, I use the phrase "in chains".

The fuck machine doesn't have a vibration mode. You need to go to the machine, use CTRL, and click the black and silver vibrator. This will detach it from the machine. Then use " i " or " u " to activate. Using those buttons will allow you to scroll through the speed settings, eventually turning it off again. To reattach the vibrator to the fuck machine, you just need to hover the item at the attachment point where you got it from. It will hook up on its own.

Bed is not activated for her, you must use fast sex option with coma mode if you want to do that.

I see.

Thank you
