Hmmm … maybe a tag that might be suitable for images with this theme might be Forced Seduction …a theme found frequently in Western literature (mainly romance novels and soap operas) wherein man-on-woman rape eventually turns into a genuine love affair …
And then have "Forced Seduction" also imply "Rape", because that's central to the theme/trope.
That way people looking for rape that leads to seduction would be able to find that theme even if they don't want to see rape in the absence of 'forced seduction', and people who want to avoid rape regardless of the outcome will still be able to avoid rape, including images that have this theme/trope.
Any tagging experts have an opinion about creating a new 'Forced Seduction' (implies Rape) tag?
Based upon how the site is focused on tagging what is being shown in the picture (with a few exceptions such as offscreen character dialogue), a tag similar to "Forced Seduction" or a similar named tag, should not imply rape. Not because it isn't consent, but because the rape tag is also implies sex. Rape on Furbooru implies forceful, non-consent, sex.
Thus "Forced Seduction", or whatever the tag will become, should instead imply grimdark , making it its own special tag among the more darker tones tags the site has.
