Cabin by the Lake

"Fine, honey," Natalie answered softly. Looking at Mark, she
asked, a stern look in her eye, "Do you need a special invitation?"
Mark looked up at his mother. He could just make out her firm
nipples which seemed to want to poke through the fabric. Glancing
at her crotch he could just make out the folds in her mound. He got
out of the water.

As he passed his mother on the path she slapped his butt, remarking, "Naughty boy."
Natalie got some ground beef out of the cooler and started making
some hamburgers. "Say, how about burgers tonight?"
Kim said, in unison with her brother who came in, "Sure, mom."
As Natalie set the hot burgers on the table, she called out, "Get
'em while they're hot!" As they all sat down at the table and were
enjoying the burgers and sodas, Natalie casually interjected, "You
guys can get out of those wet suits after we eat."
After they were done eating, Natalie pumped some water up for
dishes. As she was washing the dishes, she said, "You guys should
probably get those wet suits off. I sure don't want you to catch your
death."

Kim walked over to her mother just as she was rinsing the last
dish. "Mom, are you serious? Do you know what you just said?"
"I am and I do." Natalie looked over her shoulder at Mark who had
already removed his suit. Walking past the table she turned up the
light full flooding the room in a bright glow. With the light to its
full brightness Natalie could clearly see her son. She immediately
noticed his penis was fully erect, pointing out directly in front of
him. "Kim," she remarked, "Mark isn't timid." As Kim turned around
she noticed her mother stroke her brother's shaft. "Even your brother's dick isn't shy." Natalie reached down and cupped her son's
nut sack, commenting, "Even his little nuts are tight."

Kim joined her mother's side staring at the things between her brother's legs. Mark noticed her stare and smiled. He could see
quite a bit of his sister, too, even though she still wore the bikini.
Being wet afforded him practically an unobstructed glimpse of her
round tits. He noticed her nipples were much more pronounced. As he
looked at her crotch he could just see, barely though, the roundness
of her vaginal mound. Damn, he thought to himself, why doesn't she
just take it off. His thoughts reverberated in his head. "Yeah, sis,
take it off. Let me see you without the swimming suit."
Natalie noticed her daughter staring at Mark's crotch. She smiled
a remark, "Kim, go ahead and touch it. I don't think he'll mind."
Natalie stepped back as Kim advanced her hand toward her brother's
erect shaft. "Go ahead, honey, feel how stiff and hard it is."
Kim bent down a little andput her hand tightly around his penis.
As she slid her hand on its length she slipped a hand against her brother's balls, massaging them gently.
Natalie noticed her daughter's smile. She whispered in Mark's ear.
"Mark, untie her suit. See what she's hiding."

Mark slowly reached behind her back and undid the strap. As her
bra fell to the floor he saw her little breasts flop downward. So
that's what they look like. Having seen how nice his sister's breasts
were he wondered what she hid down below. Slowly he pulled the strings of the bikini bottom.
As he pulled the strings of the bikini bottom Kim stood up, pulling
his penis with her, affording her brother with a generous view of her
fuzzy, blond-hair mound. Enjoying the feel of her brother's genitals,
she wondered if he'd enjoy the feel of hers. Heck, she thought, there
was only one way to find out.

With her constant slow stroking Mark felt like he had to use the
bathroom. He was surprised when she nuzzled against him allowing
his hand to touch her vaginal mound. As he slowly massaged his sister's sparsely-hair pussy he probed his finger down the small sslit. He noticed that she was moist down here and it wasn't due to
the water droplets that still clung to her pubic hair. Probing his
finger down her slit it suddenly slid into her vaginal cavity. She
sighed loudly just as Mark shot warm white liquid against her fuzz.
"Gee, Mark," Natalie remarked, as she had witnessed the entire
escapade, "you never were very neat." She grinned, adding, "You do
realize that you have to clean your sister up now."

Mark stepped back abruptly withdrawing his finger. He looked at
his mother and went to get a towel. Returning with the towel he
simply replied, "Okay, fine then, I'll clean up the mess I made."
Natalie snatched the towel from his grasp. "Oh no you don't, young man. You have to lick off that spunk of yours."
"Oh, mom," Kim remarked, "that sounds yucky."
"Yeah, it probably does, honey. But let him do it anyway. I can guarantee you'll like it."
"Oh, mom?"
"Yes, Kim, what is it?"
"Why don't you get out of your wet suit." Smiling, she added,
"Afterall I wouldn't want you to catch your death."
"Tooshay," was really all Natalie could say. Thinking a minute,
she casually asked, "You really think I should?"
"Yeah, mom, you should," Mark interjected quickly, hoping she'd
oblige.
"Well, honestly, Mark, being older I don't get chilled as quickly. Besides, if I do I can always turn up the heat." Kim butted in. "Oh, come on, mom, don't be a prude." Looking at her mother's suit shimmering in the light, she added, "Besides, you're practically naked now." "Yeah, I know," Natalie giggled. "Kind of frustrating, isn't it? Your mother is teasing both of you, isn't she?" "Yes, you are," Mark chimed in. He walked over to her, his penis swaying wildly, and deliberately swiped his hand slowly against the exposed part of her breast and slashed a finger against her blond forest. "So, can we see more of you?" He stepped back, joining his sister. "Oh?" she asked, crossing her arms. "You wanna see your mother's nipples?" "Yeah, mom," Kim answered quickly. "Hell, let us see the milk jug corks." "And I suppose you'd want to see under this ribbon, too?" She touched the crotch ribbon. "Come on now, mom," Kim remarked. "Why don't you just take it off?" "Well, smarty," Natalie shot back, "I'm not going to." As she turned up the heater, she added, "I'll be fine. Besides this'll dry in no time." She slid her hands down her suit, deliberately touching her breasts and crotch area.

Natalie stood in the center of the room directly in front of the light. This allowed them a generous view of her body. She even turned sideways letting them see the sides of her breats. Standing there, sideways to her children, she pondered a risque move. She knew her nipples were hard and, probably, clearly defined. She knew that it would be a bold move. Heck, why not flaunt the side of her pussy too. "Hey, kids," she called out, pulling the material away from her breast and crotch, "Take a look!" Both looked as Natalie openly flaunted one hard nipple and even let them see the roundness of her mound. Admittedly both were glued to their mother's nipples and vaginal mound. "Geez, mom," Mark exclaimed, "nice. Why not let us see it all?" "Nope, not just yet," Natalie replied, as she let go of the material. "Maybe later. But," thinking a moment, she added, "maybe I won't." Looking at her daughter, and noticing her son's cum on her fuzzy-haired mound, she ordered, as she put her hands on her hips, "Mark, you really should get that stuff off of your sister. It gets really sticky after awhile." Flopping her breasts in her son's direction, she added, "Like now!" Kim laid down on the bed, resting her head in her arms, as Mark
came over to her. She had liked the sensation of his finger inside her.
She wondered if his tongue would be as nice. As Mark approached her
she spread her legs, allowing him a generous view of her fuzzy mound.
She sighed in escatasy as his tongue glided against the outside of
her mound, slowly lapping up the white spunk that seemed to cover
every little hair. As his tongue licked her mound it slid downward
against her slit and probbed her vaginal lips. As his tongue fringed
her lips, it slowly slid against her clitoris which caused to cry out.
Mark sensed he had found a very sensitive spot on his sister and
glanced his tongue against it periodically as he tried to glide it
deeper into her cavity. Suddenly she started to breathe harder and
he could feel her pussy, hell her entire body, shiver.
"Oh, mom!" she cried out as she came in what seemed an endless
torrent of her vaginal cum.
