As I have already removed the game from my hard drive, I can't post a picture for you of any of the countless scenes where she resists and is forced. Lines like "Get your hands off me!" are used commonly, and the men persist.
If Tamara decides afterwards that it wasn't so bad or she actually enjoyed it, it means she doesn't press charges against her rapists, not that she wasn't ever raped. She could just as easily decide that she wasn't into it, and need therapy to recover from a night of being gang raped in an alley behind a bar. Truth is, this game is full of rape, which Tamara and her friends frequently decide they are into after the fact.
However, as a counterpoint to your contention that Tamara is unable to be the victim of rape, I will remind you that there is a game ending condition if you choose to go back to the bums that raped your friend. "They RAPE you forever, bad idea." That line alone means the game contains rape without question.
And, as such, it should have a "rape" tag so people who are not into forcing sex on unsuspecting individuals aren't subjected to it and people who are looking for that content can find it.
You seem defensive about this, so I will add that no one is accusing you of rape because you played this game. Playing a game with a "rape" tag is not illegal. I reiterate, the tag is there so new players have an idea of what the game contains, and followers have an idea of what changes have been made. I have no idea why you are resisting the inclusion of a tag the game truly needs to describe its content.
Fact is, it would probably help this game get some exposure (sorry, had to do it) if it had more tags, and "RAPE" is a tag it should really have. (according to f95 definitions)
