Beauty parlors sometimes do anal bleaching. And im done explaining. Maybe someone else who doesnt get angry at people who cant get a simple joke. Its so simple in fact that its stolen from family guy. Yeah. People who watch family guy understand this joke.

Asian pronunciation, L and R tend to both sound like R. So the joke is meant to be the guy who wanted his anus bleached, and due to his accent made it sound like he wanted to be fucked in the arse.
