I'm looking for a story from a number of years ago involving a female scientist (biologist maybe), who leads a research trip where they study the mating behavior of some apes (or monkeys, gorillas, or another species). There are a number of students (postdocs?) along, including her boyfriend (husband?). In the end, different people hook up, including the professor and a male student, and the husband and a female student, in tents, in between research observations of the apes. It's a very well written story, I think in multiple parts, but I can't find it on Literotica. Any help is appreciated. Thanks!
