Going out to a club to attract other men. Making a chastity slave pay for more time locked. There are so many variations of this theme. Maybe in the latter case she'll use some of his money to buy him a lap dance... while his cock is snugly in its tube.
And she talks him right through the process. He KNOWS he is paying for his own frustration ... but he does it anyway.
Just re-read that caption and her words would really sting a guy. She's proving to him just how low he has sunk and not leaving him any chance to rationalize about it. Hope she spends some of his money on sexy lingerie to keep him well teased and frustrated.
She's also demonstrating how she can manipulate him however she likes. She knew from the outset she could talk him into actually making things worse for himself ... and she simply amuses herself by making him do so.
