Mark and Chris IV: Pretty Panty Exchange


Cassie closed the door to her room, the phone pinned between her shoulder and
her ear, listening to one of Marks more sexually explicit messages. She
wondered if her mother had gotten it as well, she had been smiling kinda funny.
Actually, she had been rather upbeat here lately since Sunday when Mark had
brought her home. She pushed it aside, putting it up to her moms usual jitters
over her brining home a new beau, and actually having found a Homo Sapiens this
time. Her book bag hung from the other shoulder, and she dropped it on her bed
as she began to sort through her mail. Reba followed her into the room, and
dropped into the overstuffed recliner in the corner, an evil grin on her face.

Cassie dropped her mail, and frowned.

"You have had that look on your face ever since we got out of that stupid test.
What is up with you today?"

"Wouldn't you like to know."

"Yeah, I would...and you are gonna tell me, or you don't get any of my moms
brownies."

Reba put on her most shocked facial expression, before leaning forward, and
sharing her secret with her friend.

"Well...you know how Chris kept smiling at me during the test?" She was
referring to the ASVAB that they had taken earlier in the day, in school. It
was administered every year by the local recruiters of all the branches, and
the Captain of Mark and Chris Reserve Unit had volunteered them to help, since
they had graduated from the very same school.

"Yeah..."

"Well...we did a whole lot more..."

* * * *

After the test ended, Chris offered to walk Reba to her next class. They held
hands like newlyweds, and Chris even carried her book bag. It was easy for her
friends to tell why she was so jealous over him.

"Can I see you tonight?"

"You know I have dance."

"So, after dance then."

"It'll be late, but your apartment is one the way home." She smiled as she gave
in.

"OK, but no funny stuff mister," she said in her best Tweety imitation, her
favorite cartoon character. He leaned down, and kissed her forehead.

"You know...," all of a sudden, she grabbed his hand, and pulled him into a
dark class room. It was a biology room, but she knew from walking past it
almost all school year that nobody was in it this period. They left the lights
out, as she locked the door. Chris picked her up, and sat her on a table. Their
lips locked, as they told each other without words how much they had missed the
other since last night.

"Don't you have class," he managed to say somewhere between their tongues
assaulting each other, and two pairs of hands groping the opposite body wildly.

"Don't you have a hard on?"

That argument was hard to resist as her hand grabbed a hold of him trough his
uniform trousers, and began to rub. A moan escaped his lips, as she unzipped
him, and dropped to her knees before him. With one quick motion, she inhaled
him, all the way down her throat, and then swallowed.

His hands grabbed the edge of the table she had just been sitting on, as his
breath began to come in short bursts. Her hands grabbed his ass, and without
even thinking about it, his hips began to thrust in a slow, easy motion. Her
moans could be heard around his stiff prick, as she slobbered all over it,
licking and sucking, her fingers teasing his balls, her tongue wrapping around
the head, and squeezing and sucking.

He looked down, and could see right past the table, into her loving eyes, his
lips forming the words she wanted to hear.

"Love you." She opened her throat again, and swallowed him whole, then let her
throat close, and massaged him like that. It was to much for the horny Marine,
and he exploded down her throat. With a squeal of delight, she began to
swallow, as he slowly pulled back a bit, allowing her to breath between bursts,
until his balls where drained.

With a big happy smile on her face, she sat back on the table, and pulled him
into her arms. Their lips locked again, and he could taste himself in her kiss.
Not that he cared. He loved his little baby, as disgusting as the thought was
to him.

She leaned back, and wrapped her legs around him, as he began to unbutton her
blouse, and reached in, unhooking her bra, and sucking in her nipples. His
teeth began to tease her, nibbling and flicking, as his other arm dipped
between her legs, and began to rub her pussy through her panties. She closed
her eyes, and pulled him in closer with her heels in his back, moaning his
name.

His lips left her tits, and he kissed from her neck to her shoulders, then down
across her chest, as he pulled her panties away to the side. His cock was hard
again, and pressing against her thigh.

"You fucking tease, give it to me!"

"You want it baby?"

"Yes..." She tried to sound sultry, giving him her most seducing, innocent
look.

"How bad?" He began to rub it across her pussy lips, as he sucked and flicked
her nipples with his tongue.

"Really bad, ohhhhhhhh," she moaned, as her head flew back, his dick touching
her clit. But as much as she tried, she could not pull him in.

"Please Chris, please, please, please!"

"I like it when you beg baby, " he moaned as he bit her neck.

"God, you fucking bastard, just fucking fuck me!" Her eyes where half closed,
her voice slightly up pitched.

"That's not nice." He bit her nipple, and pulled his dick back slightly.

"OHHHH GOD! Chris, please, please, please, give me your hard big beautiful
dick, please, I'll be such a good girl tonight, just please give it to me!"

He smiled, and with one smooth motion, he stuffed it into her, filling her all
the way, their lips locking as he held her down. His motions grew fast and
furious, as he began to pound into her, each thrust harder and harder, her
moans and groans muffled into his lips. His jump wings and dive bubble scrapped
across her nipple, driving her crazy, as his uniform turned to trash around
him, his dick pounding into her.

Her hands came up, trying to push him up, diving under his shirt, and
scratching down his back, leaving red streaks.

Growling like a attack dog, he reared his whole body up, slamming into her with
the force of a piston in a race car, her legs pulling him in tight, as her eyes
rolled back in her head, and she orgasmed all over his stiff prick. Chris came
with her, shooting up into her what he had left. Then he collapsed atop his
baby, breathing hard, and wondering how he would ever explain this one.

"You sure you can handle me tonight?"

"Don't worry. I'm gonna go home right now, and eat my wheaties."

Reba laughed, as their tongues began another dance of passion.

* * * *

"No way."

"Way."

"You fucked, right there, in the biology room?"

"Yup...and it was good!" Reba closed her eyes, and Cassie could just see her
seeing herself on that table, being fucked by her stud muffin (that's what she
called Chris when he was not around...he violently objected to the label).

"I don't know what's wrong with Mark, he's been kinda funny lately."

Rebas eyes narrowed suspiciously, and she took a serious look at her best
friend.

"As in?"

"I don't know. He's still being his sweet self, and he still is great in bed,
and everything, but something about him is on edge. Like today, he jumped on me
about nothing after the test, then apologized, and then was upset at himself."

"He's like that. Don't worry about it. My god, the two of you had your first
date Saturday, fucked right away, and now is only Tuesday. Even Mark has limits
to the things he wants to think about. And they tend to be fairly small." Reba
shook her head. Mark was her brother, and she would defend him not matter what,
because he would do the same for her. The fact that he was weird...well, that
was par for the course. He was after all her brother And besides, he was kinda
that way with every girl he had ever dated, and Reba remembered them all.
Personally she gave this relationship about a 1 in 3 chance of making it
through the month, but she would never say that.

"I guess you are right. But still!" She began to sort through her mail again.

One letter caught her interest. It was from Anne, a girl that had moved up
north at the end of last year. That had really sucked, she was a great person.
She pulled out a single sheet. That was strange. Usually she would write about
7 pages to every girl in their group, and then they would have to compare notes
to find out who did not get what. The page had a huge header, reading . . .

"Pretty Panty Exchange!"

It's the Pretty Panty Exchange Just Imagine, get 36 pairs of panties, for the
price of one!

Just put your name in the second place on the address list at the bottom, and
mine at the top, and then mail this to six people!

Then mail one pair of panties to whoever is at the top of the list of this
letter!

When you get to the top, people start sending you panties!

It went on several more lines, about how the whole thing worked. She put it
down, and did the math. Actually, if you send it to more then 6, you could get
more, but that did not matter.

She flicked the letter to Reba, and told her to read it.

"Sounds kinda cool."

"I bet you got one at home."

"I am sure I do...wanna do it?"

"I don't see why not...might solve my problem as to what to wear when I go out
on a date with Mark."

"I hope you wear more than underwear."

Cassie smiled. "Never longer then about half a hour. He's a fast eater you
know."

They busted out laughing when they realized how that sounded, then headed to
the mall.

* * * *

Mark shot his best friend a queer kind of look, then pushed the bar all the way
up, before letting it come back down, repeating the motion 4 more times, and
then placing it back on the rack.

"So you are telling me you had sex with my little sister right in our school?"

"It's not our school anymore."

"Motherfucker, you know exactly what I'm talking about." Mark bounced off the
bench, and flexed his arms back and forth. They where standing in the exercise
room that was part of the apartment complex they inhabited, a room they didn't
like half as much as the local Y, but it was convenient, and they had both had
excess energy this afternoon, if for various reasons.

"Made her miss class, too."

"Damn, man, you do know how to bust a brothers balls. She is the one who
attacked me." Chris was almost pleading now, slowly realizing that maybe he
should not share all the explicit details of his sex life with Mark. It was
after all his best friend sister he was talking about.

"Yeah, right, my little foot, my little sister attacked you. And I was raped by
a rabid goat last night." They switched out the weights, putting 225 lb. on the
bar.

"Do you mind going first, I want you to cool down before you spot me."

"Fuck you." Mark dropped onto the bench, and began pumping.

"So what's up with your other woman?"

"She's flying in this afternoon. I talked to her mom yesterday, and she said
she would go to pick her up. We don't get along any fucking way, so she asked
me to stay away."

"Stay of execution." Mark pumped the bar slowly and deliberately, spending as
much energy as possible on each rep.

"I know dude. I guess I'll have to just bite the bullet and come clean to her."

"Reba knew you where fucking around on Claudia, right?"

"Yeah."

"Don't do anything stupid, bro."

"Trust me." Mark frowned, and pushed the bar back on the rack.

* * * *

It had been four weeks since that letter had arrived, but now 36 brand new
pairs of panties graced Cassie's bed. They where arranged in 6 x 6 neat rows,
covering her bed. Reba was sitting in the recliner in the corner of the room,
with Fluffeles in her lap. The little white dog was growling contently, as the
girl scratched him between the ears. Cassie had for the last 15 minutes been
trying to decide which pair she should wear on her date, something Reba was no
help in.

"I still think you should wear a thong."

"He'll think I'm a slut."

"You are, so what's the big deal?" Cassie gave her friend the finger, and
continued to study her choices. It did not really matter. She was wearing a
white top, which her bra and full breasts where trying to bust out of, and a
short black skirt. Her hair was growing longer, and almost covered her
shoulders now, in brown waves.

"Hey, let me ask you something." She turned, and faced her friend. Reba would
get upset when she used that serious tone, and felt ignored.

"Do you think sex could be better then it is now?"

"No, I cum every time with Mark."

"I mean, I do, too...but still!" The girl was insistent. Cassie just turned
away, rolling her eyes. In that Mark and his sister where equal. They where
never satisfied with their performance in something.

"You are the one that disgraced our alma matter by having sex in it. To me that
qualifies as a great sex life."

"You did it with Mark in the pool, with your parents no 50 feet away."

"They where inside, and safely out of view."

The doorbell rang, preventing any counter arguments, as she decided to go with
her best friends advice, grabbing a thong, and pulling it up under her skirt as
she slipped into heels, and hurried down the stairs, ignoring Reba's calls that
she looked like a slut, after all.

Downstairs her mother was laughing at whatever Mark was whispering in her ear,
like he liked to do to tease her dad, and holding a white rose. She never did
figure out why Mark always gave her mother white, and her a combination of red,
yellow and white. After all, white is for passion.

As she reached the last step, he stepped forward, wrapping her up in his left
arm, his right smoothly presenting a dozen red roses, and his lips locking on
hers.

Her body pushed into his, her breasts rubbing against his chest, as his tongue
once again took possession of her mouth. She could feel herself getting wet,
and his hand grabbed her ass. She pushed him away, giggling. Her mother had
turned away, and quickly took the roses, promising to put them in a vase.

"Reba here? I saw her car out front."

"Yeah, upstairs, why?"

"Then lets go, I owe her money."

She loved the way he drove. It was about the only thing he did holding still.
Only his feet, eyes, and arms moved, as he would shift gears, and fly around
other cars. The T-tops where out, so the wind played through her hair, as she
leaned back and closed her eyes. A moan passed her lips, and she could hear him
laughing.

"What's so funny?"

"You moaning." She smiled.

"I'm just horny for you baby."

"Ohhhh, sweety, talk dirty to me." They laughed again, then Cassie sat up, and
Mark got nervous. She had that serious look again.

"You know, our one month anniversary is this weekend."

"Shit, Hallmark ain't even got a card for that."

"Listen, buster, I'm serious here!"

"All right baby, so what would the lady like to do for this highly important
event in our future?" He absolutely did not see the big deal, but if she did,
he could play ball.

"You never did take me to the dance party. And then I have a suprise for you."
He frowned. The reason he had not taken her to the amusement park just outside
of town, and the dance party was because he thought the whole idea was stupid.
It was one of the MTV dance things, and he figured anything with MTV on it
could only be a disaster.

"Only because it's you."

"Why thank you."

"Don't make a habit of it." He smiled as they pulled into the parking lot of
the movie theater. She knew he would have already purchased the tickets,
because he was like that. Holding hands, they walked into the theater, where
Mark quickly led her all the way to the back (he knew she was liable to sit
somewhere weird...like the middle), and sat in the middle of row, folding up
the armrests of the seats around him, and letting her sit on his lap, her feet
over the seat to his right.

"Do we really have to go to your little park party?"

"Yes," she groaned, her face buried in his chest.

"Fine," he groaned back as the lights went out. As soon as it was dark, she sat
up, and they began to kiss, their tongues trying to out race the images
flashing across the screen in the previews. His hands supported her, pulling
her closer, and caressing her breasts and ass. She tried to sit in his lap, but
he turned her away, so that she had her back towards him. Pulling her into him,
he began to rub, squeeze, and caress her breasts through her top, as he bit her
neck, and worked his hand under her skirt. Her head came back, but she bit her
finger so that she would not moan out loud.

His hand came all the way up, and he found her thong. She could almost see the
surprise on his face, as his bite loosened for a second, then he clamped on the
other side, whispering something she could not understand, his finger rubbing
her through her panties.

Her hips began to rotate as he found her clit, and his index finger began to
massage it. Slowly his fingers slipped around the lacy garment, and began to
invade her. One after another, they passed her lips, teasing and rubbing them,
as they moved deeper and deeper, caressing and exploring, until he had three
fingers in her.

Squeezing her clit with them, his other hand began to squeeze, flick, and pull
on her nipple in earnest now, massaging her left tit as he nibbled her neck.
His ring finger flipped her lips back and forth, playing with them, as his
middle and index fingers squeezed and pulled her clit.

Cassie almost bit her tongue off trying not to scream. Her hands gripped the
arm rests, and her neck arched back, eyes screwed shut, as Mark began to
whisper how hot she was in her ear. Then suddenly that feeling was back. The
same feeling she remembered from the kitchen that morning, as his fingers where
inside of her, caressing SOMETHING that she did not understand, and driving her
straight up the wall.

Marks index finger continued to rotate over her G-spot, rubbing the rough patch
of skin (at least that's what he figured it was, even though his knowledge of
the inside of the female anatomy was limited to what to rub, lick, and suck
on), as he played with his baby. His top hand had switched, and was now sliding
up her hot skin, under the blouse, finding her bra, and slipping inside.

Spreading her pussy lips open, his ring finger began to play with her labia.
His index finger kept teasing her in that one spot, and his middle finger went
to work on her clit, as his teeth found her earlobe, and he began to nibble, as
he whispered to her.

Cassie could not take it. She thought she was drowning, as sweat broke out all
over her body, her back arching, and her cunt on fire. His fingers seemed to go
faster, faster, faster, and then she exploded, the orgasm starting deep inside
of her, and radiating out faster and faster, with each flick of his finger
growing stronger.

She could not hold it in, and a loud, high pitched scream flew from her lungs,
as she almost leapt of his lap, then collapsed into his arms.

Suddenly she became aware of their surroundings. Cassie looked up, and noticed
that people where turning around, and she wondered if the guy in the projector
room right above them had just gotten the show of his life. She buried her face
in Marks chest, as he lifted her up, and carried her out of the theater.

Mark wrapped his arms around her, kissing her all the way, as he carried her
out the back, and pushed her up against the wall. Immediately, her legs wrapped
around his waist, and their tongues began to wrestle anew. She sucked his
fingers clean, then held him tight as she gasped for air.

"I guess we'll need to find a new movie theater to go to."

"They are building a new one over by Stone Field." Her voice was still shaky
from her orgasm.

"I know... by the time I'm ready to see another movie, it should be ready. You
hungry?"

"Yeah. You think we can go without making a scene?"

They held hands as they walked around the front, Mark rolling his head from
side to side as he considered a answer.

"Probably. If you can keep your hands to yourself this time." She punched him
as hard as she could, something he found rather hilarious.

* * * *

In Marks opinion (and Chris as well, but neither really knew that, only
suspected it), everything they had ever believed about MTV Dance Parties had
been true. They where standing in the mass of gyrating (even though both of
them preferred the term throbbing) teenage bodies, and even some older ones.
Their own little theory said that they fell into three categories. A.) Older
guys preying on younger girls, and therefore scum, b.) Old people trying to
feel younger, and therefore idiots, and c.) Older people who liked the music
younger ones did, and therefore confused, and therefore idiots as well. Mark
frowned, as his hips moved with Cassie's.

Her back was towards him, and her ass grinding into his hard dick. It had been
that way for at least 15 minutes, and he was convinced that this was not
healthy. His eyes wandered across the crowd, and meet with Chris. The message
his best friend sent was rather clear, even though they spoke no words. Mark
looked away, before Chris raised his fees for going with his best friend on
this outing rose. Reba was having a good time, which worried Mark. Maybe his
little sister would be corrupted.

He turned his attention back to Cassie, who was clapping and cheering as the DJ
ended the last song, and told everybody to "get jiggy with it," popping in Will
Smith, and pushing Marks limits over the edge. He hated Will Smith, the only
"Rapper" who got that label.

"Lets go baby, I can't wait anymore, I need you NOW ." He whispered into her
ear, but she could tell the urgency from the way he pushed his groin into her
ass.

"Well...I guess!" She turned around and smiled, their lips meeting for a long
passionate kiss. Holding hands like newly weds, they walked out into the
parking lot, Mark checking that he had not been robbed, which would have been
cause for mass murder.

"I don't think anybody would want your old wallet."

"Hey, me and that thing have been through allot."

She walked around to her side of the car, and he stepped up as if to open her
door.

"Do I at least get a kiss for offering to open your door?"

Her arms came up, and their lips meet again to express their passion. Mark took
the chance to run his hands down her back (which was exposed due to the tie-off
T-shirt she was wearing), and over her skirt (which he would have never allowed
Reba to wear, it was WAY to short), and to her naked legs (which he rather
liked, in his biased opinion). Coming back up under her skirt, he hooked his
fingers into her panties just as their kiss broke.

"And just what are you doing, young man."

"Whatever I want."

Stepping forward, he pinned her body against the Camaro, and pressed his lips
on hers again. His tongue invaded her mouth, and pressed against hers, with the
force he had learned she liked.

His hands took firm hold of her panties, and ripped them away, then pulled her
legs up around his waist. She moaned into his mouth, as he got out his hard
cock, pushed her up once, and then sunk her down onto it, impaling her with one
hard drive. Breaking away, she was breathing hard, trying to push him away and
speak at the same time, but her lack of oxygen did not allow her to follow
through on all three. Not that it mattered, he was stronger anyway.

Holding her in place, his lips locked down on her again, and he began to bounce
her on his hips, moving faster and faster. With each thrust she was impaled
harder and further on his hard cock, her breath coming fast and hard, trying to
not pass out from the strength of his assault, and the lack of air from his
kiss. Her arms wrapped around his neck, and she tore herself away from his
lips, gasping for air.

Biting her breasts through her shirt, he smashed into her again, again, again,
each one harder then the one before, her ass pressed against the car, her hips
against his body.

"OHHHHHH God! What are you doing to me!"

Mark did not listen, just kept fucking her, driving in stronger and stronger,
his breath coming heavy and labored as the familiar feeling took hold of his
balls. The tightness moved up, slowly, slowly, inching forward, until he would
explode out his dick.

"OHHHHH BABY!" Cassie screamed out loud, as she was pushed over the edge by
what he was doing to her. Her orgasm rocked her, and then again as he exploded
in her. Pulse after pulse of his cum shot into her being, each one driving her
high again, until his sweaty, tired body rested up against her, spent.

"That's was a new one."

"It's all your fault." He grinned as he placed her in the car, then walked
around and dropped into his seat, starting and rolling out of the lot.

"I don't even think so."

"Yeah it was, the way you dance."

"You are SO full of shit." Her hand reached down, and caressed his as he
shifted through the gears, flying towards the interstate, speeding before he
even hit the black concrete. Never taking his eyes of the windshield and
mirrors, he shifted across three lanes of traffic, and accelerated again, the
engine roaring out loud to match the Gun's N Roses song blasting out of the
speakers.

"I don't see how you can have rap, heavy metal, and a soft rock all in one CD
changer. Isn't there a law against that."

"It's not my fault you have bad taste. So what is my surprise."

She reached back, placing her bag in her lap and smiling.

"If I told you it wouldn't be a surprise, now would it?" He shot her a evil
grin as he pulled up in front of the apartment.

"New personal record?"

"Almost, not yet." He got out, holding her door by the time she had her seat
belt undone. Walking into the apartment, she pushed him towards the kitchen.

"Get something to drink or something, I'll call you when I'm ready."

"Excuse me, but I think I..."

"Please, just humor me after raping me in the parking lot." Her eyes batted at
him, and he relented, putting his hands up and walking into the kitchen as
Cassie walked down the hall, closing the door to his bedroom. He could see the
light come on under the door as he gulped down the remainder of their orange
juice. Chris would be pissed at that, some part of his brain told him, but he
would worry about that latter.

"You can come in now." He walked down the hallway, and listened at the door,
before opening it, and walking into his own bedroom. He took three steps, then
stopped and stared.

Cassie had stripped down, and was wearing nothing put a pair of sheer panties,
with a matching bra. Her body was splayed across the recliner that took up the
far corner of his room, her legs spread, and her finger sliding in and out of
her lips, making subtle sucking noises as she smiled at him.

The second he regained positive motor control of his body, he exploded forward,
covering the distance in under a second. But she was ready for it, spinning out
of the seat, and putting it between him and her.

"Down boy."

"You have no idea what I'm gonna do to you."

"I have a pretty good idea," she whispered as they circled the chair like cats
over lunch," but this is my show. Sit on the bed, and relax, enjoy baby." Mark
stopped, and looked at her, not sure what to think about that offer. Shrugging
his shoulders he took his place, and looked at her expectantly.

Cassie dimmed the lights, and turned on the stereo with the remote, letting
soft music fill the room. Slowly she kneeled over Mark, and began to dance for
him, her hips and ass swaying before him, his hands reaching out to touch her,
just to be gently pushed away.

"No touching...this is a eye-feast only." Moving back up, she slowly spun
across the room, and stripped down naked. Mark almost came of the bed, but she
waved him away, and the next pair of panties and bra came on. Again she came
closer, this time grinding herself into his leg as she danced over him. Just
before the lust in him took over, she backed off again, and the next pair clad
her body.

Mark noticed the trend. Each time, there seemed to be slightly less material.
In the dim light, every time she approached him from the shadowy recess of the
corner, it was as if part of the panties and bra had simply disappeared. Each
time he would catch his breath as she backed off, then lose it again when she
ground her tits, pussy, and ass into his body, almost teasing his cock to
explosion. And each time she would back off just before he attacked her.

Finally, she returned to him in nothing but a lacy thong bikini bottom. Mark
reached up again, and this time she let him cup her breasts, his fingers
rolling her nipples as she danced over him. Slowly she turned on him, so that
he had to sit up to keep up the touch on her breasts. Her back rubbed against
his chest, and she reached back, pulling up his shirt.

Their skin touched, and he almost felt as if she was burning him, as he pulled
and flicked her nipples, soft moans escaping her lips as she dry-humped him
through his jeans.

Her hips pushed up, her ass-cheeks dragging up and down his stomach as she
opened his belt and pants, pulling them down, and then biting into the bottom
of his boxers. Pulling them down, her body bent down over his, until they where
naked together. His hands traced down her body, and he pulled the thong of her,
twisting and caressing her in his arms like a little kitten.

Pushing her down gently, his body lay atop hers, their lips finally meeting,
and their tongues expressing the heat they felt for each other. His hands
traced down her back, wandering to her ass, and grabbing it. Her legs wrapped
around his hips, and began to pull him into her.

Mark pushed his head into the sheets next to her, and pushed his knees up,
groaning as she filled her in the same moment, his entire momentum pushing him
deep into her. Kneeling between her legs, he was able to fuck her deep and
hard, each thrust bringing out a loud moan from his baby, his hands still
cupping her ass. Pushing herself up, her legs took a hold of him, and she sat
up on his lap, riding him.

Her new control let her control the rhythm, and she bounced herself up and down
on his lap, fucking herself on his hard rod. His lips locked on hers again, his
fingers gently squeezing her ass.

One finger moved forward, slowly, probingly entering her ass. She moaned out
loud, as it began to move in and out in the same rhythm as his cock pounding
into her. Then another, and another, until finally three fingers where in her,
teasing and spreading her ass open slowly and gently.

Cassie could not take it anymore, and threw her head back, screaming out loud
as she orgasmed.

Mark held her tight, slowing down, breathing hard as he kissed his lady, gently
laying her down on the bed, and cradling her as he lay beside her. His fingers
withdrew slowly, still massaging her ass.

"That was interesting."

"Ain't I always?"

"Of course sweety."

Mark kissed her, as he slipped behind her, kissing her back and neck. Gently
rolling her onto her stomach, he slipped into her from behind, slowly pumping
her with gentle strokes.

Pushing her legs apart with his, his finger slowly pushed into her again,
spreading her open as he fucked into her.

"What are you doing?"

"Relax and enjoy."

Slowly he pulled out, and pushed into her ass, with one smooth full push.
Filling her all the way with one motion, she moaned out loud.

Laying his full weight onto her, he wrapped his arms around her, biting into
her neck. With each thrust she moaned out louder, as he stuffed her from
behind. Her legs spread out, as she tried to push herself up, his weight
controlling her.

"Ohhh god, baby, ohhhhh!" Her hips began to pump up and down, in the rhythm
that he was fucking her with.

Mark squeezed her tits, his dick pumping in and out of her, her moans rising
with this speed. Using his weight to press into her, lubricated with her cum,
he fucked her harder and harder, each thrust pushing him higher, until he felt
like he would be ripped apart by his own dick.

Cassie cried out loud, as Mark rammed into her, fiercely taking control sure of
her body.

Mark rocked back, and drove in, his weight pressing down into her, pushing all
the way in and exploding in her. Wave after wave of cum shot into her ass, his
body still fucking her.

Cassie screamed out again, and came with Mark, as their bodies drove each other
higher and higher. His hands squeezed her tits hard, and she groaned out, her
clit spasming as it spent itself.

Kissing her softly, Mark held her tight, caressing her softly. His dick grew
soft and slipped out of her, as they cradled each other.

"That was a new experience."

"Ain't I always."

"Can we do that again."

"Anything for you baby."
