Thank you bro! It workedFL
You need to increase the punishment level (top right on the screen).
You do that by having either the girls or MC punished.
For the girls, distract them from their homework (ask for sex things, 2-3 times a day).
For MC, spy on Rachel in the shower in the morning, don't do your chores, have yourself a drink in the interior and get caught.
When punishment level is at "paddle", be in the corridor after diner and wait for some noise to come from Chloe's room.
Same applies for Emily
