I undersatnd what you are trying to say, its FUN and not weird but you guys are finally doing something different and exciting ... ??
How old is the neighbor's girlfriend ? younger or older than your wife ? Is She having a good time as well ??
Once you get at least two topfree bare breasted women together its a party and MUCH easier to invite more and more people ... just a thought but you might try a video of your next topfree party get together and you and sue could show it to " other topfree people possibilities " as a way to invite them to the FUN new lifetsyle that you have discovered ...
It is a problem to get across the idea of being a bare breasted female in public or at home around friends without SOME people thinking that you are " swingers " or people that are just into exhibitiitism
If the lady is HAPPY and feel SAFE with doing it and is supported by her " significant other " being boyfriend or even girlfriend its GOOD and Normal & Ok !
Is Sue still spending less and less time at home dressed ... ?? Does she do any outside stuff like gardening or sunbathing outside or mowing the lawn ?
BTW, do you have any kids ? or do the neighbors, I am trying to see how other people's kids generally react to seeing adult female bare breasts, unless they themselves have been breastfed as a baby .... ??
Keep up the GOOD Topfree Breast lifestyle Sue and SPREAD the word to " others " ...
Maybe you could plan a TOPFREE Valentine Days Party .... ???
Bare breastedly yours,
