It was a serial will lots of chapters (50+).
There’s a mom, dad, two sons, and a daughter. They also had a girl staying with them named Lexi because she couldn’t live with her dad. They buy an RV and go take nudist trips. They meet another camper (Lexi’s dad) and get them in on the fun. Their Pastor Jim also finds out and joins in too, regularly.

Saw the stories and they were good. Don’t remember who wrote them though
One of my favorites. Hasn’t updated in a while, but there’s plenty there to enjoy for quite a while.
