Fūzoku Tenchō Monogatari (風俗店長物語)

I discovered this series a couple of days ago. It's finished now, but it's about fūzoku and it's set in the very familiar environs of Kabukichō. As far as I know, no one has translated it yet. The title can be translated "A Sex Shop Manager's Story." It isn't listed on the publisher's site, so I guess it's out of print now. The artist Tani Kaminashi (上端たに) seems to specialize in this setting. Definitely not for little kiddies.
