Love the game but in stuck with Maria in the bathtub. I entered her pussy and after trying to pleasure her for like 30 minutes to continue the story i ended up just leaving. the only shiny part is her left breast but i cannot reach it. Don't know what to do.
The Maria bath is side content and not required to advance the story. To "finish" it, you have to interact with various parts of her body on all the different screens in the bath. Even though they aren't highlighted they should be interactable. After you wash enough different spots Maria should say something and then you can leave the bath.
