Wonderful photos and progress! The warmer weather seems to have really helped move things along and let's you take this fun outside to a broader potential audience. The bikini pics are just mouth watering, involuntary licking of lips...
So great you were able to get her to go for that walk, and then to even lift her top to flash you! Your wife must really be enjoying this as well - despite her initial reluctance. Hope she had a big smile for you in that pic...
And going to McD's and sitting there - not just to get the milkshake and leave quickly! Amazing thinking this all started just 6 months ago...
Think you should make a rule of your own: she can not wear a bra at home [maybe even eventually when people stop by, or at least your friend] and same for weekends when going out for errands, shopping, walks, for a beer / dinner, etc. Have it become the norm and wearing a bra the exception. I started this rule a while back and am slowly expanding the when / where this rule "must" be applied...
The best part is now frequently it has become automatic without any reminders from me... and that is a huge change from where it started!
Thanks for documenting your adventure, providing detail and of course the photos!
