Finally, the man on the other side of the stall can bear it no longer, and cums deeply into John's throat. John greedily swallows all that he can, but gags a bit on the sheer amount of seed being produced. As the man's still orgasming member slides out of John's mouth, he does his best to begin lapping it up off the tip of the organ.
The man is obviously enjoying himself, letting out several moans and other bestial noises as the whole door between them shook. Finally though, things quieted down and John began to lick the stay bits of cum off of him.
"Man... that was amazing..." He panted lightly. Lets see, what were you supposed to do with these things again? Doesn't the person on the outside leave before the guy on the inside comes out, to keep it anonymous?
John finally lifted himself to his feet, walking over to the sink to wash his hands. He suddenly heard the door behind him swing open though, obviously this guy didn't feel like waiting. Curious to see who exactly he just serviced, John looks into the reflection in the mirror in front of him.
