The voice is coming from a gloryhole

You step back looking fearfully at the sheet but it doesn't move again. You peek around the side and see nobody there. Must have seen something, but you coulda swore somebody said
"Hello?"
There it was again! Still quiet, muffled, like from a dream, only also insistent. Then you realize it's not coming from in front of you but behind you. You turn around and see no one there but for the first time notice a fist-sized hole in the wall. You bend over at the waist, brushing your blonde hair behind your ears, green eyes squinting as you peer inside into darkness. "Is somebody there?" you say nervously.
Something long and thick and black pops out from the hole so fast it bumps you in the nose from almost a foot away. You gasp as you realize it's another big black cock, this one you can see is thick and veiny. "Don't be stupid, blondie," the voice says as the ebony fuckpole quivers in anticipation of your attention.
