I'm actually thinking that pipe is a strong contender for one of the terrorist words (pipe bomb). It popped in to my head last night.
Switch is a strong contender, the three clue implies it's correct.
I'd go:
Face
Dress
Switch
Not sure from there. Princess seems like a weird fit for blowjob, unless filthy is being very heteronormative
. Because face, dress, princess is surely just woman, right? I guess Rose could be a blocker on that, maybe.
Other potential words: root is an old timey euphemism for sex, and box is a not old-timey euphemism ...
Face
Dress
Switch
-- start to feel bad about answers --
Princess
box
