KARACHI, Pakistan  In Pakistan, a flogger is known only as the Taliban’s choice whip for beating those who defy their strict codes of Islam.

But deep in the nation’s commercial capital, just next door to a mosque and the offices of a radical Islamic organization, in an unmarked house two Pakistani brothers have discovered a more liberal and lucrative use for the scourge: the $3 billion fetish and bondage industry in the West.

Their mom-and-pop-style garment business, AQTH, earns more than $1 million a year manufacturing 2,000 fetish and bondage products, including the Mistress Flogger, and exporting them to the United States and Europe.

The Qadeer brothers, Adnan, 34, and Rizwan, 32, have made the business into an improbable success story in a country where bars are illegal and the poor are often bound to a lifetime in poverty.
