This is Part 4 of a new series about Rebecca. It's fictional, but she
is real. I'm not really a writer, but people seem to enjoy my
stories, so I thought I'd keep writing. If you haven't read my other
stories, I'm not into romance. I'm into really nasty sex. You might
want to read Parts 1, 2 and 3 before you read this one, in order to
know what's happened so far.

Rebecca the Exhibitionist Slut - Part 4 - Donna's Challenge

That evening, I picked up Rebecca, her daughter Fiona and her son
Kevin and we headed out to join up with Rebecca's half sister Donna
to participate in the first night of the Slut Contest.

The girls were really excited not knowing what was going to happen.
They were both dressed in real slut-trashy clothes. Rebecca wore an
extremely short red dress that was just two pieces of cloth held
together with little strings of red cloth tied at the sides near the
waist. The front and back panels were separated by six inches of bare
skin on each side which clearly revealed that she had no underwear
on. The fabric was so shear that every detail of her big pierced
nipples showed through and you could even see her pussy hair pressing
against the front. In addition, the sides of her huge tits were
easily visible with every movement she made. The dress was held up by
spaghetti straps over the shoulders. Red platform heels completed her
outfit. Fuck, she looked yummy!!

Fiona wore a denim hip-hugger mini-skirt that she had torn up to her
hips on both sides and was so short that we could see her asscheeks
when she walked. Her cutoff white t-shirt was so old and worn that we
could see right through it and gaze at her ripe nipples. Of course,
we could also just lift the shirt about two inches to expose her
nipples. Black flip flops completed her outfit. She wore no panties.
Pure fuckmeat!

Kevin was only 14 and Fiona was 16. Kevin started chuckling softly
because he was the only one besides me who knew what was going to
happen. He had told me how to get to our destination and we were all
anxious to get there.

The minimum security detention center was in a seedy part of downtown.

"Holy fuck!!" Rebecca said as she realized where we were.

Then we saw about 20 teenaged boys between the ages of 14 and 16
standing out front who Kevin had invited to the "party".

"Donna fucked the guards so we could have a little party with the
inmates and the boys that Kevin invited," I explained as Rebecca and
Fiona just stared at the boys. "Donna said there are about 30 inmates
right now and most of them are black guys who had minor offenses."

As we parked in front of the run-down building, Donna came running
up to the car looking like a cheap whore. She had on a short green
dress that had rips and tears all over it so her pierced nipples
showed and her pussy was also exposed. Her clit ring looked really
sexy. It was obvious that she had cut the dress open in strategic
places to expose her charms. It also appeared that the dress had cum
stains all over it.

Donna was grinning and excited as she said, "Here's the challenge!
Whoever fucks the most guys tonight wins! So count the fucks in your
cunt, your ass and your mouth! You get extra credit if you drink piss
and suck cum from each others' cunts and assholes!"

Rebecca looked at Donna and said, "Damn, girl, you look absolutely
trashy!"

"Thank you, bitch! So do you!" Donna said laughing. "And your cunt
daughter's tits look like they need to be sucked bad!"

"Forget my tits, Donna! I want you to drink the piss out of my cunt
right now! Let's see if Kevin's friends like it!" Fiona quipped.

Fiona jumped out of the car as all the boys watched and she stood in
the center of the sidewalk and pulled her skirt to her waist, loving
the stares from the horny young guys. "Get down there and open your
mouth, Donna, so I can piss right down your fucking throat!"

Donna was down between Fiona's legs looking up at her cunt
instantly. She licked Fiona's snatch quickly and then just sat there
waiting for Fiona's piss.

As the piss started to flow in Donna's mouth, Rebecca said, "Drink
every drop, you dirty slut!! You know you love it!!"

Fiona, Donna and Rebecca were in slut-heaven now as the teenaged
boys gathered closer to see the filthy show. Fiona watched their eyes
staring at her pissing cunt and it thrilled her beyond belief to be
so dirty.

"Look at her gulp it down, boys!" Rebecca said. "Your piss looks so
fucking delicious, Fiona!! I'm going to need some later to wash all
the cum down my throat from these boys!"

"Show them your cunt, Mom!" Kevin said.

"My pleasure, Kevin!!" Rebecca said with a big smile as she lifted
the front panel of her dress and spread her legs so the boys could
look at her pussy. "Do you think your friends would like to fuck me?
Why don't you show them how you lick me?"

Kevin knelt down in front of Rebecca and spread her cuntlips so he
could stick his tongue inside his mother's twat.

"Whoa!! Do it, Kevin!! Eat your Mom's pussy!! Awesome!!" one of the
boys said as he started rubbing his cock.

"What a whore!! I want some of that!!" another one said.

"Look at her face!! She loves it!! She's feeding Kevin her cunt!!" a
third one said.

Rebecca was holding Kevin's head to her pussy as she said, "And I
like to fuck him, too, boys! I love his hard young cock inside me!!"

Donna finished drinking Fiona's piss and was licking her lips as she
said, "Thanks for your piss, Fiona! Now let's get inside and fuck!"

Kevin got up and we all went to the door where a big black guard
welcomed us and let us in. Then he locked the door and said to follow
him. We all followed him to a big room surrounded by cells where the
inmates were watching us. There were four more guards that I counted
and one of them pushed a button and all the cell doors opened. The
big room had some excercise equipment and some mats spread around on
the floor.

"Fun time, guys!!" the big black guard announced as the inmates
rushed out to gather around the girls. "Just behave yourselves and
share the pussy with the boys here and everybody will get fucked
good."

The next hour was a blur of wild sex. The girls were naked in a
heartbeat and Donna yelled, "Don't forget to count!"

That's the last thing I remember Donna saying for a while, because
her mouth was filled with cock most of the time. The same was true
for Fiona and Rebecca. At one point, all three girls were doing
triple fucks, with a cock in every hole.

Rebecca had an inmate in her cunt, an inmate in her ass and she was
begging three of Kevin's friends to fuck her mouth and spray their
cum down her throat.

Fiona had sat on one of the youngest looking boys' cocks as he laid
on a weight-lifting bench and she was leaning over on him as a big
black inmate who was probably 50 years old with a huge cock was
shoving it up her ass. A younger white inmate and a younger black
inmate were waiting for Fiona to get the cock up her ass so they
could mouthfuck her.

Kevin was watching Donna finish her first triple fuck on one of the
mats. As she let the cocks slide out of her cunt and ass, he said,
"Hey, Aunt Donna....can I use your mouth? I gotta piss real bad!"

Donna looked at him and said, "Of course, Kevin!! Just let me get
another cock in my cunt first. C'mon guys, I need a big one!"

A strong looking black inmate got on the mat and Donna quickly sat
on his cock and gasped from the size of it. One of Kevin's friends
was standing behind Donna and said, "Look at the cum dripping out of
her ass! Damn!!"

As the guy Donna was sitting on played with the rings in her tits,
Donna leaned to the side and said, "Okay, Kevin....use my mouth for
your toilet and then just fuck it!"

Kevin was a nasty young fuck and he relished the chance to drain his
piss down Donna's throat. He just smiled and sighed as he stuck his
semi-hard cock in Donna's mouth and started pissing.

As Donna was gulping down Kevin's piss, he said, "You ought to come
to school with me sometime, Aunt Donna, and just drink piss all day!
My cock feels so good in your mouth!!"

After Kevin finished pissing her held Donna's head and started
fucking her mouth. Just then Rebecca came over between fucks and
said, "I'm going to suck that cum out of her asshole for some extra
credit, Kevin! I'll show it to you before I eat it! I know how much
you like that. You just keep fucking her mouth!"

Rebecca got down real low and sucked on Donna's asshole and moaned
as the cum filled her mouth. Then she looked up at Kevin and a bunch
of the other guys and opened her mouth to let them see the huge
puddle of yellowish-white cum inside it.

"You're going to make me cum, Mom!!" Kevin groaned as he watched and
slammed his cock as deep as he could in Donna's throat. "Eat it now!!
Eat it and go back for more!!"

Rebecca was wild with perverted lust as she swallowed the nasty load
and quickly sucked out more cum. Another inmate had come up behind
her and was on his knees working his cock up her ass as she showed
the next mouthful to the guys. Kevin was cumming down Donna's throat
as the guy Donna was sitting on was cumming in her cunt.

As soon as Kevin finished feeding Donna and she pulled off the guy's
cock in her cunt, she rolled over and spread her legs under Rebecca's
face and said, "Now suck the cum out of my cunt, Becca, and swallow
it for us!!"

Rebecca was sucking her cunt immediately but Donna didn't get to see
it because one of Kevin's friends climbed over her face and stuck his
cock in her mouth and came almost instantly. The minute he pulled
out, another inmate shoved him away and stuck his cock in Donna's cum-
covered mouth. Kevin watched his mother clean out Donna's cunt,
saying, "I love watching you eat cum, Mom!"

"Thanks, Kevin!! I want to eat the cum from your sister as soon as
those two guys finish with her!!"

Kevin looked over to see Fiona doing a standing double-fuck. Two
tough looking inmates, one Mexican and one black, had her sandwiched
with their cocks in her cunt and ass as she stood there between them.
Kevin moved over to watch and Fiona was moaning as the guys fucked
her.

"You look sexy as hell, Sis!!" Kevin told her. "Mom wants to eat the
cum out of you when they finish!"

Fiona turned to Kevin and gasped, "These guys are number nine and
ten!! I sure hope Mom's hungry!!"

Rebecca had finished her most recent assfuck and came over to Fiona
and said, "I want that cum, Fiona! You can eat some cocks while I
suck it out of you!"

Kevin watched Fiona cumming and he said, "I want to see you suck the
cum off the cock in your ass, Fiona! Will you do it for me?"

"You dirty fuck, Kevin!!" Fiona gasped. "Of course I will!! You want
me to suck his balls, too?"

"Good idea, Sis!"

As I waited for the two guys to finish doing Fiona, I looked over
and saw Donna fucking one of the young boys on a bench while one of
the guards was shoving his nightstick up her ass. Just before one of
the inmates stuck his cock in her mouth, she yelled, "You like
buttfucking me with that pole, you rotten bastard?" Then she laughed
and took the new cock in her mouth. Donna was such a dirty slut. I
loved her.

When I looked back at Fiona, she was cleaning off the cock from her
ass with her mouth while Rebecca was eating all the cum from Fiona's
cunt and ass. She kept pulling back occasionally to show me the cum
before she swallowed it. There was cum all over her mouth and face
and she was lost in this perverted paradise. She got even more turned
on as she saw the look of pleasure and approval on my face as I
watched her eat from her daughter's holes.

Later, one of the guards brought out a big tarp and spread it on the
floor and the girls laid down so all the guys could piss on them.
They were absolutely drenched with piss and loving it.

Soaking wet, Donna smiled and said, "Now who wants to fuck three
pisswhores?"

Some of the guys grabbed them and positioned them on all fours, side
by side, and suddenly there were hard cocks in each mouth and in all
three asses. It appeared that all 50 guys had shot at least one load
in the girls and some were now working on their second or third fuck.
I've always loved watching girls getting fucked in the mouth and ass
while they're on their hands and knees. It seems like the ultimate
slut position.

Before we left, the guys took the girls to the showers and washed
them off and fucked them some more. The last three guys told the
girls to get on their knees and open their mouths.

"We want to see who the best pissdrinker is!" one of them said with
an evil grin on his face.

Rebecca did her best and so did Fiona, but Donna was obviously the
best in this competition. She seemed to be able to open her throat
and just let the piss flow right to her stomach.

Suddenly, the big black guard came in and said time was up. He
explained that some new inmates were on the way and we needed to
leave before they arrived.

As we walked back through the big room, all the inmates clapped and
cheered as the girls stayed naked and wiggled their big tits and
waved at the guys. Kevin and I had collected the clothes and we all
headed out to the car. Kevin's friends just stood around on the
sidewalk getting a few final feels of the girls' tits, cunts and
asses. Donna was making sure all the boys knew where she worked so
they could come fuck her when they needed to relieve their swollen
cocks.

Then Donna asked if some of them could do her a favor and come by
the next day at noon to help her. She explained that there was a
group of snooty sorority girls coming in for lunch and she wanted the
boys to slip in the kitchen and cum in the salads so they could all
watch the snooty girls eat fresh semen without knowing it. Ten of the
boys volunteered to help Donna and she promised them all blowjobs for
their help.

Then we all got in the car and drove away. We found out that Donna
had been dropped off by a friend so she needed a ride.

"Okay, let's find out who won!" Donna said excitedly.

Fiona said proudly, "I fucked 17 guys and sucked the cum off four
dicks after they fucked my ass!"

We all clapped and Rebecca said, "Good girl, Fiona!! I fucked 19
guys and ate at least ten loads of cum out of your cunt and ass!!"

We cheered again and then Donna said, "Damn, you two are really
tough competition! But I fucked 22 guys and three nightsticks! I also
drank the piss from five guys! And I ate the assholes of all five
guards!"

Everybody clapped and cheered and Rebecca said, "You won round one,
Donna!! What a blast!! I think Fiona should drink your piss while I
drink hers to celebrate your victory!"

Fiona perked up when she heard that and said, "Yeah!! Let's do it!!
I just love pissing in someone's mouth when I'm sucking the piss out
of a cunt!!"

Donna loved it and she said, "Let's do it at the concert hall!! The
symphony is playing tonight and it should be letting out soon. We can
give all those highbrows something to remember!!"

I could see the excitement on Rebecca's face as she looked at me.
She knew how much I loved watching her get nasty in public.

"Ohhhhh, yessss!!" Rebecca moaned. "We need to set this up just
right! Let's have Donna sit on the fender of the car and hang her
legs over the side, spread real wide, while Fiona bends over and
drinks from Donna's cunt! Try to keep your mouth away from her cunt a
few inches so the people can see her piss going in your mouth, baby!"

"I will, Mom!!" Fiona said. "I'll drink her like a fountain! And
I'll spread my legs as wide as I can so you can sit under me and
catch my piss in your mouth!"

"They're going to fucking shit when they see your sweet 16 year old
cunt pissing in your Mom's mouth, Fiona!!" Donna snickered. "And you
can sit with your legs spread open to expose your cunt, Rebecca!!
Fuck, this is going to be fun!!"

"And I'll piss, too, while they're staring at my cunt!" Rebecca
added. "Be sure to watch my clit, Rick....this might give me a
touchless orgasm!!"

We drove to the concert hall and our timing was perfect. We stopped
by some big flood lights along the sidewalk between the hall and the
parking lot. As the girls got out of the car, we saw some people
dressed in suits and fancy dresses beginning to leave the building.
Kevin and I stood to the side as Donna got up on the front fender and
spread her legs. All three of the girls had goosebumps all over from
the anticipation. As Fiona bent her head down near Donna's cunt, her
tits hung down and shook from side to side. Rebecca sat down naked on
the sidewalk and she pushed Fiona's legs farther apart as she held
onto Fiona's thighs and positioned her head below Fiona's cunt.

What a nasty sight as both Fiona's and Rebecca's cunts were so
visible. Fiona's asshole was also visible which I knew thrilled her.

"Spread your legs wider, Rebecca!" I told her.

Rebecca immediately spread her legs as wide as possible. I knew she
couldn't wait for the people to gather around.

"Your cunt is so beauitful, Fiona!!" Rebecca sighed. "I can't wait
to drink from it!! I need that sweet yellow piss in my stomach!"

"Loosen me up with your fingers, Mom!!" Fiona urged. "Show these
folks how you like to play with my pussy!"

Rebecca slipped two fingers inside Fiona's slit and worked them
around and around as more and more people gathered to witness the
girls' filthy act. Some of the people hurried by, making ugly remarks
about the girls. They didn't realize the girls didn't care. They
relished the chance to expose themselves and get extremely nasty.

Donna could see everyone staring at them and she said, "Okay,
Fiona!! Get ready to drink my piss and piss in your Mom's mouth!!"

Fiona held her mouth open as Donna started pissing in a nice arch.
As Fiona caught the piss and started swallowing it, she began pissing
right into Rebecca's mouth.

"Oh my god! That's just disgusting!" one woman said to her husband.

"Have they no shame!!" another bitch muttered as she glanced.

"This beats the hell out of that concert!!" one man said to another
as they paused to watch.

"No shit!!" the other one said. "Those sluts are HOT!!"

"Yeah, and the one standing looks like she's only 15 or 16!!" the
first one said. "I'd love to fuck her!!"

"As soon as she finishes pissing in her mother's mouth, she'd love
to have your cock in her," I said smiling at the man, who was about
45 and very good looking in his sharp tux. The other man looked to be
just a bit older and also nice looking.

"Are you serious?" the man asked.

I smiled and said, "If you don't fuck her, I think her brother here
will do it. By the way, she's 16."

The two men pondered the invitation and started nodding at each
other. Meanwhile, Rebecca and Fiona were so excited drinking the
fresh piss that they were both on the verge of cumming. Rebecca's
clit was visibly throbbing as her piss flooded the sidewalk. I had to
hold myself back from going over and sucking on it.

As Fiona and Donna ran out of piss, Rebecca started licking Fiona's
cunt.

"Now!" I said to the men. "Go fuck her! One in her cunt and one in
her mouth! Fuck her good!"

By now, the men were beyond hesitation. The sight of this beautiful
naked 16 year old girl was just too enticing to resist. They unzipped
their pants and rushed over to Fiona, one grabbing her hips and
swinging her around as Rebecca realized what was happening and
scooted out of the way.

"Fuck her hard, guys!!" Donna said, having watched the men as they
had been deciding whether to do it or not. Then she jumped down and
told Rebecca to get up on the car so Donna could suck the piss off
her wet cunt. Rebecca slid up on the hood and spread out in ecstasy
as she watched the men getting ready to fuck Fiona and knew that
Donna was going to eat her out and make her cum hard.

"Give them a great fuck, Fiona!!" Rebecca instructed.

As Fiona felt the cock enter her wet cunt, she looked at the nice
hard cock in front of her face and glanced up at the older of the two
men and purred, "I want you to your balls!!"

The men couldn't believe it and the man in front of Fiona slid his
cock right down her throat as he held her head still. His eyes rolled
back and then he looked at his friend who was groaning as his cock
felt the silky young cunt wrapped around it, and he said, "They said
fuck her hard! Let's do it!!"

The other man nodded and they got in a rhythm where they both pushed
in at the same time, filling Fiona's cunt and mouth right to their
balls and then pulling back and repeating it over and over. It was
one of the best public fucks I'd ever seen, especially with Fiona
being watched by at least 200 people from the concert. Many of the
women had abandoned their husbands, but some of the women were
obviously attracted to the scene and a few were either subtly rubbing
themselves or squeezing their husbands' cocks.

Rebecca was laying on the hood so she could see Fiona being fucked.
At one point, Donna lifted her head away from Rebecca's pussy and
glanced at Fiona. "Damn...that's a great fucking slut you've raised,
Becca!! She'll never forget this fuck!!"

"That's for sure, Donna!" Rebecca moaned. "She's putting on such a
fabulous show! Damn, I'm proud of her!! Now please put your tongue
back in my cunt! I want to cum really hard in your mouth!! You suck
me just like our mother does! I love feeding you!!"

"After you cum, would you do me a favor?" Donna asked. "Would you
turn over so I can eat your asshole? There may still be some cum in
it!"

"Mmmmmm!! There's plenty of cum in it, Donna!! You want to eat it,
don't you? Will you share it with me?"

"Um hmm!!" Donna moaned as she returned to Rebecca's cunt.

The girls were back in slut-heaven as they continued their filthy
performance. We could all hear Fiona moaning as the two cocks rammed
her again and again.

It wasn't long before the two men exploded inside her. When they
did, they just pushed in to their balls and spurted hot semen in
Fiona's cunt and throat. Fiona's eyes were watering and her nose was
pressed against the older man's pants, his cock totally imbedded in
Fiona's throat. When they finally pulled out, Fiona gasped for breath
and swallowed over and over to devour all the cum. Then she asked the
men to hold her up and spread her legs so the crowd could see her
cunt as the cum oozed out of it. As she looked at all the strangers
staring at her exposed cunt, she had another orgasm and some of the
cum squirted out of her, landing about four feet away on the sidewalk.

By this time, Rebecca had rolled over and Donna was munching on her
asshole. Fiona asked the men to turn her around and hold her cunt to
Rebecca's mouth.

"I want my mother to clean out my cunt!!" Fiona panted.

The men turned her around and held her cunt up to Rebecca's mouth as
she laid face down on the car with her head at the edge of the fender.

"Ohhhhh, yesss!!" Rebecca said as she saw Fiona's cum-covered cunt.

As Rebecca ate the cum off Fiona's pussy, Donna came around and spit
the cum from Rebacca's ass on Fiona's cunt so Rebecca could eat it at
the same time she was eating Fiona.

As I looked around, some of the men were jacking off as they
watched. It was a truly wicked sight.

Eventually, the girls were exhausted from the events of the evening,
so we said our good-byes to the two men and the crowd of people and
left.

"That was fucking awesome!!" Kevin said as we drove.

The girls just huddled together in the back seat and basked in the
glow of their wonderful evening. When we dropped Donna off at her
house, she sucked me off and then said goodnight.

I knew the girls would recover after a good night's rest so we could
move on to Rebecca's challenge in the Slut Contest the next night.
