Married for over 25yrs and during our most recent vacation was the first time ever. For her 50th birthday we went on a cruise. She bought the usual new clothes for a cruise. Shorts , shirts ,some formal wear and a couple of cute sundresses.
She wore the cute sundresses during our two excursions. To my surprise she was going completely nude under the dresses

Her reasoning was that it was HOT!!! , the top of the dresses where made to go without a bra and make's changing into her bikini that much easier at the beach - ok. For 50 she still looks great, 5'6" around 135lbs and still pretty firm small c-cup breasts.
The best was watching her climb in and out of the open back tour buses that went around the islands. She tried her best to be discreet but the tour guides got there free show

Also the occasional battle with wind. She didn't seem to let it phase her from enjoying her vacation. The fruity drinks may have helped

First and only time she has gone commando. I LOVED IT.
