This was a good one but not the one I saw, this girl seems to be into it, the one I remember the girl wasn't, she basically just sat there and endured it, she didn't enjoy it at all, and at the end it's basically alluded that she shot herself.
The one I was referring to had the girl as a high-schooler and it was her father or older male caregiver going after her all the time it's kinda an older title probably early 2000's maybe early 2010's

"Attackers" is a good one also "Nagae style" just type nsps or nsfs and loads of movies will pop up, I'm also a fan of story based JAV especially if they have subtitles attached.
