This is exactly my situation. Me and my wife work at the same place. Different offices and different bosses. The entire office know i share my wife and she is the favorite doll for everyone in the office. Few friends know and no clue for both of our families .
My ex wife didnt like it at all she was always spitting the cum. My wife is different she loves the taste and sometimes she returns back to the same bull because she likes the taste of his cum.
Well thats more than i expected. My wife will be thrilled. Although i dont do any of clean ups or suck. I just love to watch how you would fuck, treat, and finish with my wife. Yes you can take any hole in my lovely wife.
We all want to rush things. If thats the case then just go along with her. If you push her she might agree for once then you loose it for ever, but if you go as you said baby steps you will enjoy for long time trust me.
