Looking for a Story about a mother and son that accidentally go to a clothing optional beach or villa

[LoneStarWolf]

A few years ago read a story about and mother and son accidentally going to a clothing optional beach or villa, all I remember the most about it is that they slept in a tent and at some point in the story they both try nudism out separately (the mother trying it further down the beach while the son tried it in the water) I even vaguely remember some dialogue: “as he looked down he could see the white outline of his penis in the water” and “she shuddered as the salty sea air brushed her vulva” and at the end of it they both end up naked together after their swimsuits get washed away by the ocean with the son holding her bridal style.

Unfortunately that’s all I can remember, any help finding it would be appreciated.
