I visualized what I know. Years ago I worked briefly at a porno store in SF, on Ellis Street (not the Mitchell Brothers, which is more likely to have the larger spaces you describe).
Good story, well told. It is too rare in online erotic stories that a man lets others use his wife without being a cuckold. I feel it's hot when a husband turns his wife into a slut for anybody, while he is still clearly in command.
