Hate to say, but in the distant past probably would have gotten her to stop. But for some reason, ever since I found this site, would definitely let her continue.

Like HeWhoDares would also encourage her to let others touch her if she wanted. Video and photos would be mandatory. Hopefully other wives / GF's would join in. And have a feeling she would really enjoy it - she is a real closet exhibitionist and this might be just the type of event to bring her natural tendencies out of that closet!
