imminent rape
When a character is about to be raped, but the penetration hasn't happened yet.
This is different from you gonna get raped because the context in that tag is supposed to be humorous, whereas this is considered serious sexual assualt.
Add imminent vaginal and/or imminent anal as well to show which orifice is about to be penetrated. This only covers the general fact that rape is about to occur.
If the partners are about to engage in consensual sex, or if you're not sure as to whether or not the image depicts imminent rape, use imminent penetration instead.
