I think many here actually secretly do.
Not sexual meaning of it like i said, i won't enjoy process of rape regardless, but more like sweet revenge for all other female MC that was brutally raped and turned into nymphos. Turn rapists into pets instead. I know there 99,9% won't be anything of the gangbang sort in JOHN done to Jessica, or done by her hands, just a naughty thought\joke. Also, how do you imagine this situation going consensual? Thugs turning to be secret buttsluts or something? Or if done to MC, she needs to have fetish for it? Or... god forbid, "blackmail"? We'll get usual threesomes anyway if that's what you're mean.
Exactly, one of the guys can just watch. And maybe join later.
