Nothing on the recordings from Tuesday, but she is back in the office today. I've come to the conclusion that she has caught onto the recorder and is simply working around it.
A while back I noticed that the zipper to the back pocket that I hide it in was open when she got home from work. I found the recorder which made me think she wasn't aware. But, she has brought up "you're probably recording me" or "unless you recorded it all" a few times after work - at first I attributed that to her finding the other recording device but now I think it is her referring to the current attempts.
She has been going straight into the office when arriving, and straight to her car when leaving. No longer meeting up before with her bag, or dropping her bag after. But there are long periods of time on the recordings during the day without much noise. I'm fairly confident that she is leaving her bag at her desk and going off to suck and fuck during a lunch break or just a period of time prior to leaving for the day.
I still haven't found definitive evidence (such as someone remarking about her absence or asking how lunch was when she returns to her desk) but her workplace has plenty of out of the way meeting rooms that are used for calls, etc, so someone being away from their desk isn't out of the ordinary and not really remarkable.
Now that I have a working theory I'm pretty much sure of I'm going to start trying to find some ways to confirm.
I've started wearing thongs in the evenings as a way to continue to signal my desire to be emasculated. I've also found two local dominant men that are both very keen on the idea of having control over a couple. Ideally I would prefer to find a man that will take away my wife in a more direct and obvious way, and who also enjoys the idea of humiliating and making me suffer as part of the process.
