You realize you need to break the prisoner's dilema

Despite having plenty of time in this room, you realize right away it would be very easy to accidentally spend all of your time interrogating one person, only to not gain any information from it, and lose. You didn't enter this to lose and get stuck here.

With all three subjects having their stimulation on low, you figure out what is going to motivate them the fastest. You grab some tape from the table, and the remote labelled for the Pixie girl's mechanical dildo. You tear off a piece of tape, and cover her mouth with it. Her eyes widen and she starts to struggle more and moan at her sudden inability to communicate. However you ignore her pleas and turn your attention to the other two prisoners.

"At least one of you knows something, and you are going to tell me. Otherwise, if you make me lose, i will give Pixie girl here an orgasm and i will switch places with her. First person to speak up will get an orgasm before i leave."
