Yeah, I did that but I didn't get the first two preview images in the OP. Is the single choice enough to put me in the rough route? I didn't get the scenes in the gentle route either. Also I would like to know how to get the 8 different endings. I was in bed after mistress spanked me for not wearing diapers in my play through. Thanks in advance.
The first two pics in the OP are the very last scenes of Day 4, end of current content, both from the gentle route, I'm not sure if they appear in other circumstances however, they trigger when you don't go with Sarah at the end & you get punished for it by Mom/Mistress/Landlady/whatever & put in the cage where gentle Iris keeps you company.
To clarify, I'm not entirely sure but if you don't get approached by Sarah near the end & told to go with her I think the choice to make that happen is back at the first time at Justin's house, taking his place to be pissed on then eating her out (specifically doing both of those, if you get pissed on but don't eat her out I think it still won't trigger, but I don't know for absolute sure), what should happen is you choose a girl to go on a date (Susan, Kylie, Lily I think they were?) on the way home from that date you'll run into Sarah on the street, she'll demand you go with her, if you ask Iris to make an excuse for you so you do not go with Sarah, you'll get those last scenes with the cage that you see in the OP.
