Are my wife's bare breasts an invitation?

Are they?

Well, it's certainly not obviously prohibitive. I would think it would depend more on the permisterality of the woman and how she presents herself in exposing her breasts in public.

In Europe its normal to be nude, so no men won't hit on her .... in the US well then it will depend on where you are...

unusual happens.

My gf loves showing off her tits and it is most certainly an invitation. She has met more than one bull to satisfy her needs this way. She enjoys watching my reactions while she is being picked-up on by some stud right in front of me.

Well said

Yes it is , it is 99.9 % of the time, a cum on
No top in lady talk = please come and suck my nips.

very much
