Natalie's Surprize Boat Part 4

Note : This story is completely fictional!

Having kissed his sister he released her. "There, I kissed her.
Now what?"
"Oh, come on now, Mark," Natalie rebuked, "that was not a kiss."
Getting up she confronted both of them. "Now I wanna see a real kiss.
A really passionate one."
"Yeah, Mark," Tammy added, "lay a real smoocher on her."
"Hey Mark," Kimberly chided, "wanna to do a really great kiss?" She grabbed him, pulling him tight against her, rubbing his hard shaft against her pubic bush, crushing her breasts against him,
grinding her nipples deep into his chest. Giving her mother and
Tammy a better view by turning sideways to them she pressed her lips against his. Slowly she slipped her tongue against his lips causing them to part and probed her tongue against his. Further enhancing it she goosed her crotch against his letting his penis grind itself against her.
"Wow, sis, that was something!" Mark said taking a bit of liberty to palm his hands against her breasts and rub her light blonde forest.
Kim didn't seem to object to his probbing hands and pleasured herself by feeling him as well. Then she turned away and approached her mother. "Now what we gonna do?"
"Hey, I know," Tammy interceded, "how about volleyball?"
"Good idea, sweetie," Natalie answered with a smile. "Come on, Mark, lets get the net and ball." Her sudden yank caused his penis to glance off her hip causing her to smile. They waded to the anchored sailboat.
Natalie climbed aboard giving Mark a very good look at her twat.
Reaching down she grabbed his hand to help him aboard as well. However, her planning was not too good, and, when pulling him aboard, her wet foot slipped on the seat causing her to sprawl into the
cockpit. 
Mark, unable to catch himself, fell into the cockpit as well. With his mother sprawled, haphazardly, on the cockpit sole, his hand still held, he fell crushingly against her, his still hard shaft sliding against her slit, flaying itself against her thick bush.
"Oh my," Natalie sighed. "Do you mind getting off me?"
Mark, putting his hands on her thighs, pushed upward and an errant hand slipped against her crotch. Chancing an audacious move he probbed against her exposed open vaginal lips and slid a finger inward. Helping her up with his other hand drove his finger deeper as his knuckles grazed against her.
Natalie quickly yanked his hand free. Scolding him she said, 
"Now now, none of that, honey." Stepping backwards into the cabin she wasn't concerned that he was staring at her breasts watching them
quiver. "Well, come below, silly."
Stepping below he saw she was already stooped in front of a locker
pulling out the net. Stepping over to her he looked down and, apologetically, commented, "Sorry, mom. It was an accident."
She smiled up at him. "Yeah, I know, sweetie." She retrieved the
net from the locker and handed into him. "Here, take the net and
these sticks and throw them topside."
Mark threw the equipment into the cockpit and turned back to his mother who was just getting out the volleyball. Trying to be funny
he suggested, "Mom, why not grab two balls?"
Natalie laughed at his suggestion. "Well, we actually got three,
you know."
"Huh?"
"Sure, Mark, we got three balls. One in my hand," she displayed the black and white volleyball, "and two right here." Seh fondled her hand against his testicles.
"Oh, mom," he giggled allowing her hand to grope.
"It's the truth you know," Natalie smiled up at him.
Meanwhile, back on the beach, Kimberly was just standing there. 
"I wonder if we even got that stuff, Tammy."
Tammy laughed, her breasts boucning in front of Kim's field of
vision, and said, "We got at least two balls anyway."
"What?"
"Sure, don't you see, Kim? Mark always carries two with him."
Kim laughed herself at her friend's remark. "You mean down here?"
She touched her vaginal mound.
"No, silly," Tammy rebuked, "down here." She drove a hand against
her friend's fuzzy thatch gliding a finger against her lips.
"Oh, I got it now, Tammy," Kim giggled allowing her a generous feel, "right here." She groped a hand against Tammy's crotch as well.
"Yeah, right there," Tammy smiled. She couldn't help but comment,
"Oh, Kim, you're so beautiful."
Back on the boat Natalie handed Mark the ball. "Come on, lets get back." She stood up quickly, turned sternward, and swept past him allowing a breast, along with a rising nipple, to glance against his
arm. "Well, come on, honey, don't dwaddle." On her way out she grabbed some beachtowels from under the companionway ladder.
Arriving back topside Natalie bundled up the net and sticks and
cast them towards the beach followed by the ball. Climbing over the rail she slipped into the water. "I'll help you over the side."
Standing waistdeep in the cooling water she reached upward and
put her hands around his waist. "Okay, sweetie, be careful now." Being right next to the bobbing boat she gingerly helped him over the side. Her close proximity to him caused his penis to glance off her lips, slide between her breasts, and grind itself against her pubic forest. They returned to the beach.
Tammy and Kim had already picked up the net and had strung it up.
Tammy ran back to the beach, letting both Natalie and Mark see her
swaying breasts, and picked up the ball. "Well, lets play."
Natalie surveyed the net. Going to her daughter's side she mentioned that it could be a lot tighter. "Kim, you really should put these stakes back further, you know, kinda spread them out, like this." Stooping she repositioned them and sideglanced at Kim who was standing by the ropes. Deliberately Natalie looked right at her light blonde fuzzy bush. "See, Kim, they gotta be tight." Probbing
a hand against her daughter's bush she added, "Kinda like this is."
Making sure the net was now properly set up Natalie couldn't decide how the teams would be matched. She just stood there, dumbfounded, trying to decide as she looked at each of them in turn.
"Now lets see," she pondered out loud, "how about me and Kim against
you and Tammy?"
"Come on, Mark," Tammy said grabbing his hand and pulling him to the opposite side, "we'll kock their pants off."
The game began with both sides doing a wonderful job of returning.
Kim was happy to be on her mother's side as she could watch her brother easier. The sight of his now flaccid penis flopping about as he returned the ball excited her thoughts.
Kim served the ball over the net. "Here, return this," she yelled as it sailed over the net.
"I got it," Tammy said running for it.
"No, I got it!" Mark called back as he, too, ran to recover.
Mark's hand swatted the ball just as Tammy reached it. The side glance of his hand against hers caused her to loose her footing in the soft sand and she fall face down. With her flaying feet she caught Mark and he fell against her. Just before his body fell against hers she turned upward allowing his penis to jam itself into her dark bush.
"Oh, Mark," she suqealed at the pleasure, "kiss me."
Kissing her lightly he got up and extended his hand to her. Helping her up he groped a hand against her breast. "You really got nice tits, Tammy, you really do," he praised as his hand savored the feel of the soft tissue.
"Hey, you two, can we have the ball back now?" Natalie blurted out, a little peeved at the slow return.
"Hey, Natalie, you want this one?" Tammy, jokingly, displayed the volleyball, "Or would you rather have these?" She goosed a hand against his balls and fondled them.
"Very funny, Tammy," Kim laughed. "Just send it back."
Tammy served the ball and the game continued with each side scoring points until Natalie missed an easy shot and the game was over. "Ha," Tammy yelled, "we beat you." She raised her hand and
slapped it against Mark's raised hand. "See, Mark, I told you we would."
"Yeah, well, so you did," Natalie accepted defeat gracefully. 
"Now we switch sides. Me and Mark against you two. Let's see how good you really are, Tammy."
"You're on," she said as they switched sides. "Come on Kim, why not show them how the game is played."
"Yeah, lets."
Mark had watched both his mother and Kim run around chasing the ball and now he had ideas on how he might get to swipe a feel of his
own mother. He was not to be disappointed as they played. 
Natalie was all over the field. However when she and Mark both tried to recover her hand slapped the ball and his hand slapped against her breast glancing off a nipple. "Hey, Mark, hit the ball
not the boobs."
"Sorry, mom."
She rubbed her breast. "Damn, that's gonna smart.
Chancing a comment Mark suggested, "Want I should kiss it and make it all better?"
"That might work," she teased advancing her breast towards him.
As he kissed her breast his tongue lathered against her nipple causing it to swell up. "Care to soothe this one, too?" She allowed him to kiss and caress his tongue on her other breast as well.
Kim was watching up gently he licked her breasts and teased her own thoughts with the pleasure of it. She saw how much her mother seemed to enjoy it and wondered if it was really that pleasurable. 
Hoping to find out, she teased as she joined their side, "Mine are a little sore, too, Mark."
"Go ahead, honey, soothe your sister," Natalie said amused at the 
thought of it, amused at what her reaction would be as he licked her breasts as well.
"Oh god," Kim cooed as his tongue glided over her breasts, sucking
her nipples out, "that feels so neat." She felt a tingling within herself as he continued to probe his tongue against her breasts and
moaned, "Oh god Mark, eat my pussy."
Mark couldn't believe he heard what she said. Here he was standing right next to her sucking on her breasts, enjoying how they tasted, and then she suggested that. "Okay, Kim, if you insist."
Kim braced her footing in the sand, spreading her legs, as his tongue licked her slit. "Oh my god," she cried as his tongue probed her very sexuality, "don't stop, don't stop!" As his tongue probbed against her she became more aroused until finally she couldn't take it anymore. "Mark," she screamed, "don't stop, please don't, I'm coming!
Mark couldn't help but taste the dripping liquid and sucked deeper
savoring her juices against his lips. "Damn, sis," he said wiping his lips, "never thought that would happen."
"Neither did I," Kim remarked. She smiled at him adding, rubbing her crotch, "That felt so great."
"I will say one thing, Mark," Natalie commented, "you know how to 
turn a gal on."
"Funny you should say that, mom," he made light of it, "cause you're next."
"Oh, are we man enough to turn the old lady on?"
"Yeah, we're man enough," Mark grinned at her.
"Okay then, let me see if you are, smarty," Natalie giggled as she
spread her legs in the sand. Thinking a moment she advanced her thoughts, "Hey, how about if you two suck on my boobies?"
"Hey wow, Natalie," Tammy enjoyed the thought of it, "yeah." Turning to Kim she said bluntly, "Come on, Kim, let's really turn your mom on."
