so they did it or no?

nope, bum thought it was the real thing until he turned around ┑(￣Д ￣)┍

Nop.. but here I am, still wondering how could he not tell the difference between the real thing and a dildo O.o''

Well, (1) he was upset, (2) he was unprepared so it would hurt no matter what, and (3) the anus doesn't always have perfect sensory input (to be crude, can you tell the exact shape of a bowl movement while you are having it?).
