Thanks for your kind reply! I think the main issue here is my submissiveness and her full-on dominant character. When I am around her I am not too much of a man. I cannot refuse doing what she asks/orders. It’s always been like that with us two.
I do agree with you that clean-ups are very very degrading and humiliating especially if her lover is going to be watching this. But I am afraid that I`ll submit to her (as I always do) and then puke (or lose consciousnesses or something worth) when the whole thing of clean-up actually starts.
And your words about babies are exactly what I told her and she simply replied with a smile telling me that I should then simply do a better clean-up job. I think the possibility of her bearing another men’s child actually turns her on.
She also skyped me today that her boss is aware of us thinking about getting back together and he is thrilled by the whole idea (and I got the idea that he is bi-sexual!!!!!!!).
I am thinking that if we are to go through with this she`ll have to restrain when I am going to be witnessing their coupling the first time otherwise I won’t be able to cope with my emotions. Having said that, I am getting tremendously aroused by just thinking about that. It’s a love/hate type of relationship and I cannot determine what is going to prevail.
I am also worried about the risk of men’s health issues if you go without release for long time (and knowing her I wouldn’t be surprised that once I am locked up and she’s got the key – it’s going to be a long time before she unlocks me especially if I disobey her). And she probably realizes that, given my profession, I will try to avoid having the cage removed at a hospital or by someone else apart from her due to it’s degrading nature. On top of this she gave me 24 hour deadline. I need to decide soon 
(it’s only going to be a 2 week trial at first she said if I agree to her rules).
