The girls who were taken to the room after the party have mixed feelings. They don't want you to know that they get horny when they get drunk... They don't want to ask you to fuck them... But, to tell Kokoro, they came to the room because they're interested, and they're ready to have sex, so they want you to push them down... If they say "I want to do it!", they should be able to join right away... It's frustrating, but they want to do it.
