so since the topics rape, my little goto head fantasy ill worldbuild and alter while gettin comf in bed
>main characters of a series get kidnapped, held hostage for random (eg shinki and asuka as an example) from a bus stop
>third character is there, unrelated, just wrong place/time (say, lan, from battle network)
>welp, this third person is a literal third wheel to this hostage taking situation what do we do
>hostage takers decide "we use him as an example, to make the people we are extorting for ransom take us seriously".
bam, now youve got 2-3 characters who would generally never have a reason to be hanging out, forced together. then with the third wheel aspect, you can reasonably inflict any scenario on them without it seeming too out of place (you can easily make a hostage taker a depraved bisexual or whatever you want. its an inherently criminal/evil occupation. go nuts).
then i self insert as the one getting tortured. ezy pzy. starts with just malicious abuse, breath play, slapping, punching, ends with outright bdsm freaky stuff, to a heterosexual character who cant really fight back (we will kill the other two if you dont-)

whatcha think. also no homo. im self inserting, not becoming the character.
