Here is a long shot, but perhaps someone has read and remembers this story, which probably appeared on Usenet in the 90's:
Two families go camping. Each set of parents has a tent, and 4 children: a teen age boy, a teen age girl, and two 4 year olds, share a tent. The teens manage to scare the young ones enough that they insist on sleeping in their parent's tent. The two teens are then free to experiment with sex.
If anyone knows of a story that sounds like that description, I'd like to read it again...
