Any situation where you are legs and/or cheeks akimbo and feel sudden terror, for example:
- you are
getting fucked by the gardener when your
psychopathic mobster husband comes home early
- the shit you are taking is so wide, long and dry you fear it might split your ring open and/or drag out some colon with it
- two guys hold you bent over a table while a third kicks your legs open in preparation
for the gang that's about to ass rape and possibly kill you
- the glass jar you put up your ass for a sexual thrill suddenly breaks under the pressure
