Scene 24 & 25 (After Ep 4 Marianne, before Ep 4 Tiffany & Seiko 02)
I'm pretty sure I know how to get scene 25, but a bit clueless otherwise. Thanks for looking.
scene 6-when you got home,choose option "It's good enough,time to head out"
Scene 9-have sex with Vivian
Scene 10-use glory hole(it would work on third time,don't get distracted by running girls)
Scene 13-(not sure about that,but you need to stick up for Himiko in ep1 and then in ep2 after showing her cock,answer her message,which you'll receive before finding Hannah on street(answer kindly and be supportive)
scene 16-during examination by twins,you need to "let your mind wander" twice and then choose "concentrate like your life depends on it"
Scene 18-you need to have sex with Vivian in ep2 and choose option "let her take care of you"
Scene 24-call with Vivian(need to have sex with her in previous episodes)
Scene 25-choose being submissive to them.
Hope that would help
