My ex-wife always swore she would
never go topless, but we once went on holiday to Spain and met up with another couple and socialised with them most evenings, or chatted to around the pool. The wife in that couple was a confirmed topless sunbather and it was nice to sit and talk to her behind my sunglasses while admiring her beautifully tanned breasts.
One day, we all ended up on the beach together and the waves were quite high. A lot of people were playing a game of 'jump the waves' so the four of us decided to try it too, wait for a wave and then be carried high by its power.
After a few leaps my wife encountered one a little too strong for her, was swept off her feet and by the time she surfaced, found her bikini top now wrapped around her neck and her fabulous assets on display.
I though she'd be embarrassed but instead she laughed, took it off and tossed the bikini top to the shore, leapt a few more waves in a bouncy
kind of way and the husband of the other couple was casting as many admiring glances in my wife's direction as I'd cast at his wife all week.
She never wore a bikini top again.
By the second week the four of us had discovered there was a naturist beach nearby and despite us laughing and joking about it on the way to it, we all stood on the beach (both girls already topless) and the husband have this low growling, rising noise before ripping his shorts off and running, now naked, in the direction of the sea. Well, I couldn't leave the guy isolated like that so I mimicked his growl, tore off my own swimming shorts and followed him. To my delight, looking over my shoulder, I saw both ladies glance at each other, pull off their bikini panties and follow us towards the sea as well, but with hands 'strategically placed' as best they could. Another story for another day, perhaps. But my shy wife's transition from textile bather to topless bather to nude bather over the course of a week was a lovely thing to behold.
