Paying her debts.

Kira was a big spender.
She had no impulse control.

She ran up a big debt with a Clothing Store owned by a Mobster.

To pay off her debts, she had to spend one day a week for the next month (or two) pleasuring his men.

With so many guys, she did her best to keep up...

She felt dirty.
She felt shamed.

It was better than the alternative, of course.

'Three more times....three more times...'
