Several years ago, my wife and I went on a beach trip with her family. Our kiddo was almost a year old, and it was his first time to visit the beach.
Let me introduce you to my in-laws. The family had a pretty strict upbringing in just about every regard, but the kids were successes by any measure.
At the time of our vacation, Lauren was 26, her brother Cole was 24, the next sister, Lynne, was 20 and enrolled in a local college. The three youngest girls carried on the 'L' theme: Leslie (18), Lily (16), and Lacie (13). My father-in-law (50) was a dentist of some means, while my mother-in-law (46) had been a stay-at-home mom since Lauren was born.
The girls mostly took after my mother-in-law -- petite, slim-chested, and except for the youngest, brunette. Lynne was the beauty of the family, with striking athletic looks and the largest bust size of the family (I'd guess a B-cup, so still not overly large).
My in-laws had made family trips to the beach for nearly two decades, and this was my fifth time to go. We always had a great time, enjoying the local cuisine, the surf, sand, and sun. Cole and his wife Maggie (of previous story) were the only ones in the family who didn't make this year's trip, as he had some work obligations and couldn't get time off.
My father-in-law never got in the water (like... literally never), and all the women/girls dressed very conservatively. Think full coverage one-piece suits, or modest two-piece tanktops and shorts/swim skirts. This year was no different - except for Lynne.
You see, Lynne had moved out when she started college, and there had been a noticeable difference in her dress as a result. It didn't start immediately, but gradually over the first year or so of her being "on her own".
Lynne started wearing shorts that her mother obviously disapproved of, and a few times she was at a family cookout in either a crop top or a low-cut tanktop with evidently no bra. Lynne was definitely the wild child of the bunch.
On this particular beach trip, Lynne showed up with - the horror! - some bikinis. Nothing hugely sexy, just some department store halters. Only one of them really even showed *that* much cleavage, but they were all borderline scandalous to my mother-in-law and younger sisters-in-law.
Anyway, the vacation went off well, even if there was a bit of tension a few times between my in-laws and Lynne, and at least one heated discussion in my in-laws bedroom that the rest of the family could tell was going on with the wild child.
On the next to last day, Lynne untied her top and lay on a towel, back unhindered by her bikini, and earning an eyeroll from my mother-in-law. I took a few peeks while reading under an umbrella, but the most she did was lift slightly, showing some sideboob, but maintaining her decency.
She did get a wicked sunburn, though, following her older sister's insistence to get sun at the beach and paying for it with a pretty red back and shoulder.
