 As Kelly approached her corner, she quickened her pace when she saw the
beat-up old pickup truck idling nearby.  The truck belonged to one of her
favorite customers, a regular named Russell, a retired mathematics teacher.
Walking towards the truck Kelly turned her head when a woman's voice called
to her.  Crossing the street was a friend, Nicky, a fellow working girl. 
Nicky was about the same height as Kelly, but wore impractical heels that
made her seem much taller.  Nicky had bleached blonde hair and large,
artificial breasts that men either loved or hated depending on their
tastes. Tonight she was wearing an out of season flower print sun dress and
an almost dowdy sweater.

   "He got here a few minutes ago, and of course he insisted on waiting for
you," said Nicky, gesturing towards Russell's truck, "I even offered him a
discount."

   "Trying to steal my customers now, Nicky?" asked Kelly, but Nicky was
already engaging in business.

   A small car pulled over and an arm from the passenger side window waved
Nicky over.  Kelly noticed two excited teenagers in the front seat, as
Nicky hurried over.  "Girl's got to eat, Kelly," said Nicky, "Catch you
later."

   As Nicky negotiated with the boys, Kelly approached the pick-up
truck.Russell leaned over and unlatched the passenger side door and Kelly
got right in.

   "Evening, Kelly."

   "Hey Russell.  Nice to see you.  How are you feeling?"

   Russell had had some medical issues a while back, and his visits had
become infrequent.  Though he was back to his regular routines lately,
Kelly figured he was only 80% of his old self.

   "I'm great!" said Russell, "My heart's as strong a bull's."

   "That's good," said Kelly, "I don't want you dying on me."

   Russell laughed as he drove.  "Hey, I feel ripped off that I'm not your
first customer tonight."

   Kelly knew that Russell liked her to talk about her other customers, and
she was happy to comply.  "He was a knew guy, I'd never seen him around
before.  Real nervous, probably married.  He only wanted a blowjob, came
pretty quick."

   "Oh," said Russell, "So he didn't fuck you?"

   "Nope," said Kelly, lifting her skirt so that Russell could see her
shaved pussy, "That's still fresh and clean."

   "Mmm," said Russell, almost salivating, "That's good.  I don't like
sloppy seconds."

   Russell pulled the truck off the main strip and into the community.  He
approached his house and the garage door opened as the truck approached. 
Parking in the garage he waited until the door closed completely before
getting out of the truck.  Kelly got out, rounded the truck, and hugged
Russell's arm as he led her into the house.

   The first time Russell had brought her to this house Kelly had been very
nervous.  Coming here violated nearly all her safety rules, but Russell
seemed so nice she allowed herself to come here, against her better
judgement.  She was glad she did, because he was a nice guy android well.

   She lead the way to Russell's bedroom and swept the five new twenty
dollar bills off the bureau, stuffing them into her small purse.  Russell
entered behind her and Kelly turned, wrapped her arms around him, and moved
in to kiss him.

   Russell turned away, and said, "I can't kiss you on the mouth knowing
you just sucked that guy off, Kelly."

   Kelly breathed hot air on Russell's face.  "Can you smell his cum on my
breath?"

   "Jesus, Kelly, don't tease me."

   "It's fine.  Russell," said Kelly smiling.  She sat on the edge of the
bed, then leaned back pulling up her leather skirt.  She looked Russell in
the eye and said, "Is this what you want then?"

   Russell knelt between Kelly's legs and smelled her pussy.  Her pussy was
moist and warm and smelled inviting, with no recent hint of sex.  Kelly's
pussy was shaved smooth and as Russell inhaled her scent excitement
shivered through her, causing her clit to harden and her vaginal lips to
part as they became puffy with lust.

   Russell wasted no time, but licked her pussy from stem to stern, probing
his tongue as deeply as possible, scooping her wetness and savoring her
flavor.  He licked ever slowly up her stiffening lit, then crawled onto the
bed and on top of Kelly.  He had already loosened his pants and they fell
around his ankles as his hard cock pointed the way.

   Russell entered his rented whore, sliding into her cunt in effortlessly.
Kelly sighed beneath him as Russell began to fuck her, slow and deep.  This
was his favorite part.  Not cumin, but fucking.  He never altered his pace,
but slid in and out.  Several times he moved to kiss her, Kelly was one of
the many working girls who, contrary to popular belief, had no problem
kissing her clients.  After all, if you're doing something as intimate as
having sex, how is kissing a big deal?

   But Kelly realized that Russell was in the throes of passion, and would
not want to kiss her mouth that had so recently sucked off another man that
night.  She turned her head away, and Russell was grateful for that.

   "Oh, God," said Russell, "Fucking fantastic..."

   "Feels so good when you fuck me..." said Kelly, and she wasn't faking
it. She really enjoyed this.  It did feel good.

   "Gonna cum..." said the older man, an instant before he grunted, and
twitched inside her.  He pushed deep into her and ejaculated, reveling in
the orgasm.

   Kelly felt like cumin, a few more strokes and she might have.  Often in
fact, she did cum with Russell, but tonight he came faster than usual, and
so Kelly was denied her orgasm.  She felt the man's rapidly shrinking cock
fall out of her pussy and then Russell rolled over onto the bed beside her,
catching his breath.

   "Thanks, Kelly, I needed that."

   "I know," said Kelly, "You say that every time we get together."

   Kelly sat up and adjusted her skirt.  She looked over at Russell, who
seemed very relaxed.  His now limp cock was leaking a small amount of cum.
She scooped a bit up with her finger and tasted it.

   "Yummy."

   "You are such a slut," said Russell, smiling.
   "You should know, honey."
