Looking for a certain story...

I haven't read it recently, but it involved a man meeting a woman who he had talked to, and given something that did something to her breasts that made them react to food, and them going out to a resteraunt. Sherry was mentioned often, and at one point he ordered an entire cheesecake. Near the end, when the woman asked when they would leave, the man said that he had reserved the resteraunt for a week, and he gestured to a table with chains on it and a bunch of food. Anyone know the one I mean?
