You must have mistaken the time! After Monday 11:00 PM it becomes Tuesday 0:00. It happened with me as well. Believe me it's just time confusion, not a bug

It'll be active in a few days!! Wait for a few days after completing the guide! In the afternoon both bree and Sasha will confront you for having sex with both them! Then after home harem is active you can ask Sasha to have sex in your bedroom! If bree is near when you ask Sasha, bree will ask to join you. If you accept then it'll be a threesome or you only have sex with sasha.

You need to have high KP before reaching that point! If you have enough KP another option will appear saying "You should make the gym more Sexy". If you choose that she will not leave.
