In The Polar Circle

Last week two asteroids collided and one of them changed its course, striking Earth deep in Siberia.

You received permission from the Russian Federation to investigate the incident and have spent most of the last week traversing the tundra in the car you rented.

However, after two days in your travel, your car broke down unexpectedly, leaving you traversing the Siberian wilderness on foot. Luckily, soon you stumbled upon a collection of yurts belonging to the Arukha clan - a small tribe of hunter-gatherer nomads who inhabit the region. Happy to see a new face, they readily offer hospitality and assistance to you.

Soon you meet Asha - an attractive young woman whom you will be sharing lodging with during your stay...

The roleplay leans on the myth that certain ethnicities living in the far north, in the polar circle, would let visitors sleep with their women, in order to keep warm. While certainly some tribes shared sleeping quarters in order to stave off the cold, it was due to practical causes and had nothing to do with sex.
