I've BS'd my wife a lot; but I rationalize it by saying to myself that I did it to get her to be more comfortable with her body. Which is actually 50% true.
She goes braless a lot in the summer (sometimes even pantyless); and before we got out she'll ask me if it's "too revealing." I tell her it isn't, even if her nipples and/or cameltoe are clearly visible. She only realized it once (after seeing a picture I took of her where she was clearly "poking"); but I pleaded ignorance and she bought it.
I got a little more "mischievous" when we first got into nudism. She was ok going; as long as she didn't have to be completely naked in front of other people. So I would "set things up" so that she would have no choice but to be naked in front of other people lol!
For example she would wear a towel and only take it off to quickly slip in and out of the hot-tub. So when it came time to exit the hot-tub, I jumped out first; and instead of handing her towel over, I grabbed her hands and yanked her out; so she would find herself being "hoisted up butt naked" in front of the other hot-tubbers. I told her "I wasn't thinking" when she asked me why "in the heck I exposed her that way to everyone." Oops...
On another occasion I packed her tiniest beach cover-up to go to the resort. By the time we got there I again pleaded ignorance; as she put on a cover-up that her boobs kept slipping out of, and was too short to cover her butt. When she realized that she wasn't really "leaving anything to the imagination" anyway, she just went with it. Oops again.
I could go on; like the time I "accidentally" dropped her towel in the pool, and she had no choice but to stay naked in the pool area. Eventually she ended up being naked in front of other people so often that she just stopped trying to hide.
Well the good thing is that she is now comfortable with social nudity. But I am a little but ashamed of the ruses I employed to "helped her" along lol!!
