That I think was set in pre-colonial America and there was a young man from one tribe who ended up in a village of other tribe where all the young women were really turned on by the idea of hooking up with an outsider so they literally formed a reverse gangbang line outside his tent, and goes into pretty painful detail about what they do.

Which, I mean I guess that’s technically minors having sex with minors, in a hunter gatherer society where adulthood usually begins at a younger age. But still weird for a grown man to be writing a group teen sex scene.
