I have completed all main characters story without mods. Truestory code is active if that matters, but nothing else.
1) Enter the room of Kali
2) Choose "Lets have some fun (+Sluttiness)"
3) Choose thighjob (any outfit)
4) Once the scene is done, the main character automatically leaves the room, and is on the first floor. On the top right of the screen, with white letters, I can still see the stats of Kali (Friendship, Lust, etc etc all the way to H statistics ending with anal)
