At some point 15-25 years ago, I read a short story that I wanted to find for my son to read.  I have googled like mad but cannot find it.  Here is what I remember:

Set in a dystopian future, a couple puts on some special skin suits so they can have relations.  Then they discuss their desire to adopt a child and how they found a broker who can help them.  You learn that what children there are are wild and live outside the city. They drive out of the city into some ruined/abandoned area where the broker, an old man, is waiting at an old parking garage.  In the end, it is the wild kids who control the broker, not the other way around and they have used this ruse to lure the couple into their trap.

I so hope you can put me out of my misery.  These are the things that wake me up at night!
