How to convince 2 girls for a threesome

[Zev]

Went to party, girl super into me, spend all party with her and her roommate
Everyone is telling me she is into me, she is kinda cute but I'm not crushing over her.
Here roommate is cute too
Gonna see them again soon at another party, how to setup a threesome ?
Don't know if the roommate is into me

Any tips welcome
