I've already completed autumn story being at 32/32 friendship and all events. But i didn't enable sex with her, witch is kinda confusing assuming that in the exhibitionism options I can ask for sex, and there's even a message of you(Runey) saying it will only be avaible if i unlock sex on her main story, but i already finished it and it didn't have any scene of sex or anything, and I don't know if u still didn't put a sex scene with her in the gamer or i missed something.
