The Lizard King watched as the lot lizard approached the Mack parked next to his.  She tottered on her high heels and held her arms out for balance as if navigating a high wire.  She'd be at his truck in five minutes, tops.  Less if the driver refused.  Because she was on the other side of the Mack at the driver's door, he couldn't see her.

He was barely breathing, and he felt himself becoming aroused.  Not by her, but by what he was going to do to her.

The dome light went on in the cab of the Mack as the driver opened his door to answer the knock.  The Lizard King could see the back of the Mack driver's bald head and a dark crown of fuzz that wrapped from ear to ear in the back.  The bald head nodded up and down.  He was talking to her.

"Come on, buddy," he whispered.  "Do it or don't.  Quit ####### negotiating.  Get out your forty bucks and stop trying to make a deal."

The last three words came out in a shout.

The Mack cab light doused.  He couldn't see inside but he hadn't seen her enter.  The driver pulled the wraparound cab curtain closed.

There were four kinds of sleeper cabs on the road, from the "coffin" type with a tiny twenty-four-inch bed accessible through a porthole-like hatch to the lavish studio sleepers that were practically camper trailers with wide beds, showers, sinks, and entertainment centers.  Between the extremes were "condos" where the bed lifted to the ceiling to allow some headroom and "midroof" models where the bunk was on the bottom with storage compartments on top.  The Lizard King preferred the midroof, but all of the designs were big enough to allow two people to cavort inside.  Lot lizards didn't need much space.

Then there she was, coming around the front of the Mack, her hand out on the grille of the truck for balance.  The driver in the Mack had sent her away.  She was shaking her head as if she couldn't believe it.  It was obviously a refusal from the driver.  Maybe he'd said something, or gotten a quick free grope, he thought.  She paused and quickly composed herself; smoothing her hair down on the sides and tugging at the hem of her skirt.  Then she put on her game face and looked up and started toward his door as if nothing had happened.
