It's not. The bear's going to go for the throat and you'll bleed out relatively quickly after that. It's painful, traumatic, and violent. But the pain does end.
The pain never ends with rape, and the more tortuous and the bigger the betrayal with rape, the more intense the pain and the more it debilitates you.
There's a reason why so many rape survivors attempt suicide within 5 years.
Because it never fucking ends.
The bear has the decency to not leave you alive so you'll remember what it did to you, your "special time" together.
