Poolside Towels

 Natalie left for awhile leaving Kim and her brother, Mark, home alone. As Kim was extremely bored she decided to call her best friend, Tammy, and see if she could come over. Getting off the phone,
she mentioned to her brother, who was shooting video game aliens,
"Tam's coming over. Hope you don't mind."
"No," he mumbled zapping another alien. Actually he liked Tammy,
even though she always treated him like a little boy.
"Good," she answered as she went upstairs. "I'm gonna go swim," she remarked disappearing upstairs. Within minutes she returned
downstairs.

Mark looked up. "Hey, sis, that new?" He looked intently at the skimpy white bikini noticing that it barely covered her breasts. Glancing downward, he noticed the barely there bottom.
"Yeah, silly," she answered, "it is." Provacatively modeling it, she asked, "Do you like it?"
"Yeah," he cooed, imagining her without it. Thinking a moment, he
took a shot at his sister. "Kinda small, ain't it? Might as well not wear it."
She just smiled at him and, going outside, called back, "Tell Tam
I'm out back."

As she left he stared after her remembering seeing just a hint of
her breasts. He also remembered how her pussy just framed the confines of that string-tied bottom. Gee, he thought, it must look great when it's wet. Often he fantascized about seeing his sister without clothes on - but that was too much to hope for.
Returning to zapping those aliens he was interupted about twenty minutes later by the doorbell. Answering it he noticed Tammy standing there. She wore tight white shorts and a loose-fitting halter top. "Hi, Tammy," he said looking at her outfit, "Kim's out
back."

"Thanks, Markie boy," she always called him that, as she walked past him. Slowly walking past she afforded him a glimspe of her tits which he observed were a little bigger than his sister's. She went out side. Upon entering the pool deck, she noticed Kim was laying on
a lounge chair. "When you get the pool?"
"Last week," Kim answered.
"Great," Tammy replied. "Mind if I take a dip?"
Mark heard that comment. It would be great, he thought to himself,
if he could see her nude. At least he might have a chance of that.
He strolled outside.

As he entered, Kim glared at him, "Get outa here!"
"Why? It's not just your pool, you know," he shot back as he observed his lounging sister. He could just make out the outline of her nipples in the wet bra. Looking down, he noticed her pussy nicely
silouetted against the wet fabric.
Tammy rebuked her best friend, "Oh, let him stay." Kim looked at
Mark, in his awfully tight shorts, and asked, "Care to join me?"
"Sure," he smiled. "I'll get my suit," and he turned to leave.
Tammy grabbed his arm. "Don't bother," she smirked, "swim nude."
Kim couldn't believe what she heard. Was it too good to be true?
Would she actually get get to see her brother without clothes? She
was fascinated by the idea, as Tammy continued, untying her halter top, "Go ahead, little boy, just slip 'em off."
Mark was a little reluctant as his eyes were glued to that halter
top. Oh, he hoped she'd take it off. She had nice tits and he'd really like to see them.
Kim was watching and rebuked her best friend, "Oh, Tam, you wouldn't."
"Why not," she asked as she untied the knot castingBo the top aside.
Mark stared at her naked tits. Jiggling them his way, Tammy asked,
"You like 'em?" Mark just grinned as he observed how the cool breeze
perked up her nipples. She looked at the tight shorts he wore, and
commented, matter-of-factly, "Well, you gonna take 'em off or what?"
"Well," he aswered, "I always have some trouble."
Grabbing his hand, and leading him over to the lounge chair, she
replied, "Hey, no problem, Markie boy. Just let your sister help."
She motioned for Kim to do the honors as she was a little anxious to
see him without the shorts. Kim was a little embarrassed by the
possibility as Tammy continued, "Kim, it's better if he lays down."
As Kim got up from the lounge chair her brother laid down. Looking
at him, lying there, she immediately noticed the bulge in his shorts,
and gliding her hand past it, she pulled at the shorts. "Oh, geez,
Tam, they're stuck."

As Tammy approached, undoing the button of her shorts, she noticed
the problem. Jabbing her finger against the bulge, she blurted out,
"There's your problem. Tell you what, Kim, I'll take care of that while you get 'em off." As he thought of the idea of being touched by
his sister's best friend, and the idea of being seen naked by his sister, he could feel his penis swell harder. As Tammy bent over him,
her tits almost touching his face, he saw a hint of black pubic hair,
she slid her hands into his shorts flat against against his penis and
balls. Looking at Kim, she commanded, "Okay, pull."
Bending over him, Kim afforded her brother a view of her breasts,
accented by light brown nipples, she pulled off her brother's shorts.
Having never seen a guy before, Kim was fascinated as she smiled at
Tammy. Tammy was awestruck, and returned the smile, as she recalled that she had actually touched it.
As she looked at him, and his dick sticking out, she commented,
"Hey, Markie boy, nice." Mark just smiled at Tammy as she began to unzip her shorts. Suddenly, she cried out, "Damn, the zipper's stuck." She looked at Mark who was staring at the zipper, and replied, rather provacatively, "Well, don't just stand there. Help."
Mark could just make out her slit through the fine black hair as he
looked at her shorts with the zipper half way down. He was unsure
how he could help. "Oh, silly, just stick your hand in and pull the
zipper."

Mark looked at her and smiled. This was just too good to be true.
Tammy was actually asking him to touch her. Sliding his hand into the
shorts of this brunette he felt her pubic fuzz. Sliding his hand deeper into her shorts, and pulling down the zipper, he slipped a finger into her pussy just as she stroked his dick. Quite suddenly, he yanked off her shorts revealing her naked body to him. He smiled
eying every inch.

Tammy looked over at Kim, noticing she was fingering herself through the thin fabric, and commented, "Go ahead, Kim, take yours
off."
Mark was astonished at Tammy's remark. Would his sister actually
let him see her without the swimming suit. Untying her bra, and casting it aside, Mark observed her tits, with their swollen nipples,
and smiled. Quite suddenly she slipped out of the bottom. Mark saw her blond-haired pussy noticing the slit. He observed that she had
less hair than Tammy did.

Tammy sat down on the lounge chair motioning Kim to join her. "Hey,
Kim, ever wonder what would happen if he stroked that thing?" Kim,
sat down next to her best friend, and nodded, as Tammy continued, "Go
ahead, Mark, let's see what happens if you stroke it." Mark was a little reluctant, but Tammy looked at him, pleadinly, "Oh, go ahead.
We're curious." As Mark began to stroke his erection both girls were
excited as to what would happen. Shortly, Tammy looked down at her best friend's mound and, putting her hand against it, began to massage it. Kim, not the least ashamed, started to massage her best
friend as Mark continued stroking.
Suddenly Mark stopped his stroking as he heard the back door open.
"Mom's home," he blurted out.

Natalie heard the excitement out back and, stepping outside, remarked, "Oh, my, what's going on here?"
Tammy looked up, answering quickly, "Oh, hi, Mrs. Evans." Completely unfazed by the situation, she asked, "Care to join us?"
"Sure," she remarked, "I could use some time in the pool." As she went inside, she added, "I'll be right back." Within minutes she
returned carrying some towels. "You'll probably need these," she remarked setting them down on the table.
All were astonishly captivated by the fact that she joined them without wearing a swimming suit. As the cool breeze caressed her nipples they swelled up hard. Sitting down next to the two girls, she asked, admiring the naked flesh flauntingly displayed, "So what's going on?"
"Oh, not much, Mrs. Evans," Tammy answered as she looked at the
blond patch, "Mark was just showing us something."
Looking at her son, with his dick proudly sticking out, she asked,
"What?"
Kim looked at her mother, answering, "He was showing us what happens if he strokes his penis."
"Oh, sounds exciting," Natalie replied looking at Mark. "Go ahead,
son, show us what happens."
He was somewhat embarrassed, but as he looked at his mom, sitting
there without clothes, and noticing her firmer tits and her thick blond patch, he continued stroking his erection. Suddenly he erupted
with a stream of white cum.
"Wow," Tammy remarked, "just like a volcano." As she got up from the chair, she commented, "Wanna stick that thing in here," fingering
her pussy. She laid down on the deck beckoning him over as Kim, and her mother, looked on. Mark looked down at her. "Oh, come now,"
she said, "put your stick in here," and spreading her pussy lips, she
continued, "Why not, you put your finger in it.
As Mark attempted to stick his penis into her pussy, he stumbled
catching himself against her breasts. Tweaking her nipples, he shoved his dick deep into the folds of her vagina. He smiled at its tightness as he pumped his dick against her pussy walls as the others looked on. Within seconds he streamed into her just as she slimed his dick with her juices.
As he pulled out of Tammy, and stood up, Kim came over to him.
"Hey, brother," she asked stroking his hardon, "you got some more of
that?"
Mark looked at his sister, standing there naked, and decided to
give her hug. Hugging her tightly, he jammed his dick against her mound. "Sure, sis, I guess." He was excited at the possibility of
what she was asking."

Kim turned around, and bending over, said, "Go ahead then, brother,
slip it in," and bracing herself against her mother she spread her legs apart affording Mark a beautiful view of sparsely-haired pussy.
As Mark slid his dick into his sister, Natalie fondled her daughter's small tits. Not to be outdone, Tammy came over and, nudging her hand between his legs, slipped a finger into Natalie just as she started fondling Mark's tight balls. Mark reached back to touch
Tammy and feeling her belly he massaged his hand against her pussy.
Minutes later, Mark pumped his dick deep into his sister's tight pussy
and, as she felt a stream of hot cum, she came.
Natalie commanded her son to sit on one of the chairs. "Now,"
unashamed, she blurted out, "I want to feel my son's penis, hard, inside me." Sitting down in the chair his erection stood upright as
Natalie looked at him. As Kim, and her best friend Tammy, flanked the
chair, Natalie eased herself downward onto his hard dick. As his penis slipped into her he noticed she was not as tight as Tammy or his
sister. But he smiled as she humped his hardon. Both girls watched
her bouncing tits and looked at her blond pussy as Mark's erection
slid in and out. "Come on, son, gave me some of that hot stuff you
got," she pleaded as she came. Suddenly, Mark erupted into her and she
smiled, remarking, "Wow, Mark, you sure filled me up, didn't you?"
Cleaning themselves up with the towels Natalie had brought out, Tammy, seeing Mark's penis was still sticking out, asked, rather bluntly, "Can I suck on it?"
"Sure, go ahead," Natalie replied, "I don't think he'll mind."
Mark shook his head as Tammy knelt down taking his dick into her
mouth. Kim knelt down, as did her mother, as Tammy gave Mark a blowjob. Natalie reached over to fondle her tits as she slipped a finger into Tammy's tight pussy. Tammy sighed as she felt it slide
in. As she humped the finger she pumped her mouth faster on Mark's
hardened member. As she juiced Natalie's finger she had no choice
but to swallow the steady stream that Mark squirted into her mouth.
Mark was surprized that he had stayed hard so long, and was able
to satisfy all of them, as Kim came looked up at him. "Can I see what
it's like," she asked as Tammy slid his penis from her mouth.
"Sure, sis, why not," he blurted out. Standing up Mark took the
opportunity to fondle her, even slipping a finger into his sister's
pussy.

Sure wanted to do it a little differently and had him lay on the lounge chair. As she pumped her mouth over her brother's still hard
dick he watched her tits bounce. As she continued to pump his dick,
Natalie and Tammy held her bouncing tits as Tammy slid a finger into
her best friend's pussy. With her mother fondling her tits and her best friend finger-fucking her, she pumped harder on the thing in her mouth. Suddenly, pumping her brother's penis faster, she came
on Tammy's hand just as Mark throated her with a steady stream of hot,
white cum.

Not be outdone, Natalie wanted some of the action, and pulling Kim
off, closed her mouth on her son's penis. As her tits flopped Kim and
Tammy fondled them tweeking her hard nipples. Mark, meanwhile, massaged his mother's pussy as he slipped a finger into her. Within
seconds, since he was heated up by the eroticism, he erupted a trickle
into his mother's mouth.

As they stood there looking at each other, Mark hugged Tammy jamming his dick hard against her black-haired mound, remarking, "Come
over again some time."
Fondling him, she commented, "Oh, for sure."
They stayed naked for most of the day as Natalie served some refreshments. At times, throughout the afternoon, they'd fondle each other. At times, Kim would stroke her brother's dick as Natalie and
hre best friend palmed her tits.
