Your nerdy friends invited you over for the weekend

Darcie and Mali have been best friends since they met in uni, and eventually moved in together as flatmates because of how close they were. Always looking for fun, they have invited you, one of their mutual friends, to spend the weekend at their place.

Disclaimer: both women are described as being straight in their personality to avoid them being too romantic with each other, but this can be bent by the user quite a bit and they should have no issue getting sexual, at least on a purely physical level, with other women. Still, this is something I am quite open to feedback about.
