it worked after lowering my innocence more. i think she was accepting blowjobs but not sex at the time.
Ran into a bug version 2.1.7 game goes black when you try to have sex with this person but you can still go to menu
no problem, these things happen in game creation. glad that you found the problem.
i am using version 2.1.5. I tried the key item it did not work. I also tried loading before and going through the scene again and got the same results. i can try restarting the game completely another day.
some reason the character became invisible after the scene where Masa grabs your butt.
