Part 4: Will and Liza

Although Sarah had an amazing time with Liza and Will, she wished she
could have shared them with Mark. She hoped that he would be open to
their new family dynamic but like being careful with the kids, she wanted
to be extra careful with Mark as they had never talked about a lifestyle
like this despite their histories. Mark loved to role play, so Sarah
began to push more and more to age play and Daddy/daughter role plays
when they fucked. Mark was totally into it so Sarah took this as a sign
that given the right set up, he embrace his wife and kid's invitation to
be intimate with them.

Liza and Will made it clear to Sarah they wanted to go all the way with
each other, and Sarah's heart continued to melt over their shared love.
They both knew they needed to wait for Sarah to go that far, so Sarah
felt a strong sense of responsibility to ensure they had an amazing
experience. With another weekend of Mark being away coming up, Sarah told
both kids they should hold off on playing with each other.  She wanted
this knowing that absence made the heart grow fonder, and she also knew
from her own experience that abstinence also made the next sexual
experience all the more pleasurable. Both kids knew something was coming
but Sarah did not specifically tell them what. Given they had both had a
couple of fun sessions with Sarah - mostly quicker ones after their first
big one, they assumed that maybe they would have more fun with Mommy,
although they both hoped they would finally get to fuck.

That Saturday Will had a scouting activity through the afternoon, so
while he was away, Sarah had Liza shower and then made her up with their
sexy and sluty make up. She had an outfit ready to go, including Liza's
new favorite lingerie. As she got ready, Sarah confirmed that she was
preparing for her long-awaited play time with Will when they would
finally fuck. Liza agreed to hide in Sarah's room when Will got home,
and Sarah would help her finish getting ready. Will got home on time and
Sarah met him at the door. He started putting down his bag and Sarah gave
him a long kiss on the lips which Will now knew as a sign of fun ahead.
Sarah told him that tonight would be the night that he and Liza would
finally fuck, so he needed to shower and get ready. She made him
something special to wear as well, and it was waiting in his room.

Will went upstairs to shower, and Sarah returned to her room where Liza
was waiting, watching one of Sarah and Mark's videos. "Well look at
you, you naughty little slut! Are you getting ideas for tonight?" Sarah
inquired.

"I am Mommy - Will loves your strip tease video, so I wanted to get some
ideas on what I can do with him." Liza responded with the devilish grin
that was now her trademark slutty sign that she was up to no good.
"Let's get dressed!"

Sarah helped Liza into her lingerie: the sexy little black thong, lace
bra, nylons and garter. She also picked out her favorite slutty dress
that Sarah had bought for her and hemmed to be the perfect fit. It was an
ultra-tight tank top party dress. Liza looked like she was ready to be
the sexiest girl at the club. She asked Sarah to touch up her bright red
lipstick and Sarah commented that she could barely resist Liza so she
knew Will would be hard a rock as soon as he saw her.

Sarah put on new lingerie also: a sheer bodysuit that had an elegant
pattern. The bottom of it turned into a garter and nylon type with an
open crotch. Sarah finished it off with a lace thong that matched the
elegant pattern.

"Oh Mom that is so hot. I love how you can see your gorgeous tits
through the top. What if Will chooses to fuck you instead?" Liza asked
with a laugh.

"He will never be able to resist his wonderful sister who is his perfect
sexy little slut. I'm going to go check if he is ready. Go and wait in
the bathroom." Sarah said as she dimmed the lights and put on some quiet
background music. She lit a couple candles over the fireplace and a
couple others scattered around the room. Sarah walked down the hall and
into Will's room. Will turned around wearing the G-string she had
fashioned for him.

"I don't think I can wear this Mom..." Will said, clearly feeling too
shy for the skimpy garment.

"Oh sweetie, you are incredibly sexy. You're perfectly toned body looks
great in that - your sister is going to be so turned on when she sees
your hard cock trying to escape your G-string. Plus, I got this robe for
you to wear until you're ready to go." Sarah assured Will.

"Oh Mom, you look so sexy...I love that outfit!" Will responded as his
attention turned from his outfit to his sexy mother standing in front of
him. "I hope Liza is wearing something sexy too, we've been looking
forward to this for a while."

"Oh she is baby...she cannot wait either...let's go down to Mommy's
room."'

Sarah put the robe around Will and took his hand to lead him down the
hall. They entered Sarah's room and Will immediately turned around
looking for his sexy little sister. Sarah led him to the center of the
room and had him face away from the bathroom. She instructed him to face
that way until Sarah brought out his sister.

She gave him a long wet kiss and wiped the lipstick that it left behind
from his mouth.

Sarah went into the bathroom and led Liza out by the hand, stopping her
in front of the bed, way out of reach of Will. Sarah sat on the side of
the bed so she would be well out of their way. "Ok Will, your sexy
little sister is ready for you..."

Will turned around and his face lit up at the sight of his sexy little
sister standing in the candlelit room. "Your sexy little slut is ready
for you..." Liza said correcting Sarah.

Will looked Liza up and down several times, grinning from ear to ear.

"Oh Liza, you are absolutely gorgeous. You look sexier than ever!" Will
said with a loving tone. Liza giggled and did a slow, sexy spin for her
brother followed by the sexy little dance she did for him when she took
off her panties for him in the video. Having watched Sarah's strip tease
video several times with Will, she mimicked Sarah as she slowly walked
toward him, shaking her hips, dipping, and spinning. When she got just
out of reach of him, she paused and pulled the straps of her dress off
her shoulders. She slowly spun around as she pulled the tight dress down
her body exposing her sexy lingerie. Will's law dropped and he regained
his huge smile. Liza kept her swaying little dance going, turned around
and bent over to show off her tight little ass in her thong. Similar to
the video striptease, while bent over, she looked around her legs and
gave Will a wink and a smile. She turned around, put her hands on her
hips and said, "You're wearing a little too much clothing, mister. I
want to see what you have on under your robe!"

Will made a gesture that suggested, "Well then, come take it off me."
Which he made not only to be playful, but because he was still a little
shy at how he looked in the G-string. Liza did a sexy walk toward will,
swaying her hips as she had done before, and pulled open the straps of
his robe. They both pulled the robe down and Liza took a slight step
back.

"What are you being so shy about, you look sexy, Will!" Liza said with
a smile, "And now I have more clothes on..." Liza reached around and
unclasped her tiny bra, took it off and tossed it to the side. She
stepped forward again, wrapped her arms around Will and started kissing
his chest. She played with his nipples with her mouth and tongue which
tickled Will and made him laugh. He leaned over to get her attention and
they began to make out, Liza standing on her tiptoes to reach Will's
mouth. Sarah's eyes welled up as she sat on the edge of the bed watching
the tender moment between her kids. She could not get over how sweet they
were to each other and how much they loved each other. At the same time,
she was incredibly turned on and could not wait to see what happened
next.

Liza pulled away from Will, looked up at him as said, "I can feel how
hard you are Will, I cannot wait to suck your cock!" She kissed his
chest again and traced her lips down his stomach to his g-string. She
pulled it down and Will's hard cock immediate sprang to attention in
front of her. She knelt down in front of him and wrapped her hand around
his cock. "Oh baby you ARE hard!" Liza leaned forward and kissed the
tip of Will's cock and giggled. She sucked in the head of his cock and
Will's giggle turned into a long "Mmmmm..." Liza reached around and
grabbed Will's ass as he began to thrust, and she began to suck his hard
cock in and out of her mouth. Sarah began to touch her pussy through her
panties as she watched the beautiful sight of her sexy little girl
sucking her son's cock. Liza had apparently learned a lot from Mommy and
Daddy's videos as she moved her hands, one to stroke Will's cock while
she sucked him, and the other to squeeze his balls and slip a finger
toward his ass.

"You're doing that perfectly, Liza, you sexy little slut." Sarah
encouraged.

"Oh god, Liza, that feels amazing, you are a perfect cock sucking
slut..." added Will, knowing Liza would love the dirty encouragement.
"Let's stop, I don't want to cum too soon!" Liza pulled Will's cock
from her mouth, gave it a long kiss down his shaft, and kissed Will's
balls before backing up and standing up. She turned around as she walked
slowly toward the bed, Will walked up behind her and put his hands on her
waist. When they got to the bed, he helped lift Liza onto it, and held
her hips to signal her to lay down on her stomach. She did so but propped
herself up on her elbows and looked back to see what Will was up to. Will
fiddled with Liza's garter for a moment and Sarah realized he needed
help. She unfastened each of the clasps and slid back to her corner of
the bed. Will straddled Liza and kissed the back of her neck, sliding his
lips down the center of her back. He kissed both of her tight, bare, ass
cheeks, squeezing the bottom of her ass with his hands. Liza lifted her
butt off the bed and Will pulled down her thong to her knees. He grabbed
her ass with both hands spreading her cheeks before shoving his tongue
into her tight little ass hole.

"Mmmmm Will, you are such a naughty boy, fuck my ass with your tongue!"
Liza exclaimed as she pushed her ass more in the air for Will to get in
deeper. Will ate Liza's ass and reached under her to touch her pussy.
Liza squeezed from the pleasure of his touch and Sarah went back to
playing with her pussy given the amazing sight.

After a moment, Liza laid forward, pulling away from Will's mouth, and
rolled into her back. She reached down and pulled off her panties and
tossed them at Will. Will laughed and began to sniff them as they had
done during previous playtimes. Will then tossed the panties to Sarah,
who caught them with a giant smile back at Will. Sarah sniffed them while
she touched her pussy under her own panties. Liza put her knees in the
air before spreading her legs, giving Will wide access to her little
pussy.

"God you're so sexy, Liza, I can't wait to taste your pussy." Will
said as he laid down between her.

Liza used her fingers to open upher tight little pink pussy, "I can't
wait to feel your tongue and then your hard cock!"

Will pushed his tongue into Liza's waiting pussy and Liza moaned louder
than she had before. He fucked her pussy with his tongue before licking
up to her tiny clit. He played with her clit with his tongue and Liza
continued to moan and hum more than she ever had with Will. She thrusted
her hips as he licked and kissed every part of her pussy and clit. Sarah
started pulling off her body stocking, knowing her panties were trapped
under it, and she needed to touch herself more deeply.

Liza drove both Will and Sarah crazy with her dirty talk, "Oh yes Will,
eat my pussy, God your tongue feels so good on my clitty. Mmmm I can't
wait for your hard cock.

Liza pinched her nipples and bit her lip loving every moment of pleasure
Will was giving her. All of a sudden Liza came - her orgasm tensing up
her entire body as she let out a quiet squeal of a moan. Will played with
her clit even harder.

"Oh god Will that felt so good - now fuck me so we can both cum!" Liza
demanded.

Will leaned up and kissed Lisa on the mouth and Liza pulled his face into
hers with her hands. She squeezed Will with her legs, wrapped her feet
around him to pull him in close. Will looked down to aim his cock toward
Liza's pussy. He reached down to guide the head of his hard young cock
into Liza. They both braced for the feeling as Will slowly pushed his
cock farther and farther into Liza's wet little hole. Liza moaned as her
tight pussy gave way for Will's cock. Will, always wanting to be careful
with his sweet little sister, looked for signs from Liza that he was able
to push further or harder. Will pushed his entire cock into Liza's pussy
and they smiled at each other as they both felt the whole of Will's cock
being inside her.

"You're so tight, Liza, you feel so good on my cock." Will said, as he
began to slowly withdraw his cock.

"Mmmmm you cock feels so big inside me, sexy, you can go faster if you
want." Liza responded. Will did not hesitate as much as she pushed his
cock back into Liza. With every thrust, Liza let out a sweet moan. She
was still very tight but it was the greatest feeling she ever had in her
little pussy. Sarah was close to cumming herself. She had taken off the
body stocking and panties, and was engrossed in the scene playing out
next to her on the bed. The kids were in their own world, Sarah could
have been right on top of them, but they were so focused on each other
that they had completely tuned out the rest of the world.

"Mmmmm fuck me harder Will, your cock feels so good, Mmm fuck..." Liza
said in-between her moans and grunts.

"Your pussy is so tight on my cock, you little slut, you feel so fucking
good..." Will said, losing his breath from the workout he was starting to
get from fucking his sexy little sister.

"Mmm...let's try doggy fucking...fuck me from behind." Liza said
starting to sit up.

Will slid back a little and Liza turned over onto her hands and knees.
Liza looked up at Sarah, "Mommy scoot over so I can lay on you..." Sarah
was in heaven. She slid over and opened up her legs. Liza crawled up
toward her and laid on top of her between Sarah's leg with her ass up in
the air on her knees. Sarah put one arm over Liza's shoulder and slid
her other hand under Liza so she could keep touching her own pussy. Will
crawled up behind Liza and took aim at her tiny pussy. He guided his cock
back into her tight hole and did not wait to start fucking her hard and
fast. He put his hands on her waist to help his momentum.

With every hard thrust into his sister's pussy, Will's cock rocked
Liza's tiny body. Sarah became a soft cushion to absorb each thrust, and
each push of Liza's body added to Sarah's pleasure as she touched
herself. Sarah loved holding her little girl as she was being fucked. She
fantasized about doing it again as Mark would fuck Liza or as he would
take Will's virgin ass. She fantasized about Liza eating her pussy as
she was being fucked, but for now she came closer to cumming with each
jolt of Liza's body as it continually pushed against her.

Liza moaned and grunted. Will began to grunt as he grew closer to coming,
his balls slapping Liza's tight little body. Sarah began to moan and she
begged that they might all cum at the same time.

"Fuck me harder Will, this is amazing, fuck my slutty little pussy."
Liza yelled, "I can't wait to feel you cum instead my tight pussy"

Sarah did not want to intervene or get into the way of the kids' fun but
had a realization that they were so wrapped up in the moment that they
might regret their position as Will came. After all, they would remember
this moment for a long time, and they would reminder the grand finale.
"Babies...babies...trust me, you're going to want to be in a different
position for the first time Will cums in you, Liza. Liza, flip over baby
so you can see each other. You can keep laying on Mommy if you want."

Will pulled out of Liza so she could flip over. She laid on top of Sarah,
who held the sides of her ass to keep her from sliding off given how
sweaty they all were. Sarah was laying against the bed's pillows so both
she and Liza were sitting up enough to have a great view of Will without
having to hold their heads up. Will took the opportunity to lean down and
lick Sarah and Liza's pussies, which were lined up on top of each other
as Liza laid on Sarah. Both girls squealed with the surprise.

"Mmmm...two perfectly tasty pussies...I'm the luckiest son and brother in
the world." Will exclaimed.

"My slutty pussy is waiting for your cum, lucky!" Liza urged Will.

Liza's pussy was perfectly lined up for Will to sit up on his knees to
fuck her. He grabbed her waist again and Liza wrapped her legs around his
back. As soon as he was lined up, he shoved his cock hard into her pussy,
although she was not in a position to touch herself, she loved the
feeling of Will's legs thrusting against her as he fucked his little
sister.

It did not take long for Liza and Will begin moaning and grunting again.

"Ugh I'm so close!" Will blurted out.

"Mmm...give me your cum, Will, cum in my pussy!" Liza replied as she
started to rub her clit, "You're going to make me cum!"

Will was building up to his orgasm and began fucking Liza harder and
harder. He was grunting with every hard thrust. Liza started taking sharp
inhales as she began to cum. Sarah drank in every sight and feeling of
her daughter being fucked hard on top of her. She felt Liza's little
body completely tense up as Liza took in a sharp deep gasp. Will pushed
into Liza harder than ever and held his cock in her pussy and he let out
his loudest groan. He pumped his cock squeezing out his hot cum into
Liza's tight little pussy. He leaned over on top of Liza who was coming
out of her orgasm and wrapped her arms around him as he laid down on top
of her.

"OH Will I could feel your cock pumping cum into my pussy...God that felt
SO GOOD!" Liza squealed.

Will could not respond given he was out of breath from how hard of a
workout he just had.

"Oh babies, that was so wonderful, you're the sexiest little sluts in
the world. Mommy's pussy is so wet!" Sarah said, running her hands
through both of their hair on top of her. "God, I need to cum soon too,
that was so hot."

They all laughed, hummed, and moaned as they just reflected on what had
just happened. Sarah spoke up again, "Seriously babies, Mommy was so
close to cumming, I need to cum or I'll go crazy. It's time for Mommy
to have fun too!"

"Do you want to taste Will's cum, Mommy?" Liza asked looking up at
Sarah with her devilish little grin.

"My god, Liza, you are a perfect little slut!" Sarah said squeezing
Liza in a hug.

Liza rolled over and scooted up Sarah's body, sitting on her face. Sarah
grabbed Liza's ass to help her line her pussy up perfectly with her
mouth. Sarah immediately dove into Liza's tight pussy and could taste
Will's cum which was starting to drip out. Liza pushed Sarah's hair out
of her face for her, looking down at her Mommy with loving affection.
"Mmmm Mommy might make me cum again with her tongue!"

Sarah started rubbing her clit when she felt Will pushing up against her.
"I'm hard again Mom...can I help you cum?" Given Sarah was buried in
Liza's pussy, she could only respond with a humming, "Um mm" and waved
Will to come closer. Will shoved his hard cock into Sarah's waiting
pussy.

"Oh Mom, you're so wet!" Will shouted as he started fucking Sarah
hard. Sarah loved how quick he was able to recover and how much energy he
had. Sarah moaned loudly as Will started rubbing Sarah's clit with his
thumbs while thrust his hard cock into her gushing pussy.

"Mmmm...cum for us, Mommy" Liza said softly, running her fingers though
Sarah's hair as she continued to lap the cum out of her daughter's
tight cunt. Hearing her daughter's sweet voice was all she needed, in
addition to her son's fucking, to cum. Sarah moaned as her body shook,
and Liza moaned in response knowing Sarah had gone over the edge.

"Yesss, Mom, you're so sexy when you cum..." Will also said sweetly.

Liza slid off of Sarah and laid down on her side. Will pulled out of her
pussy and laid behind Liza, spooning her. Sarah rolled her head over and
gave Liza a kiss with her cum covered tongue. Liza moaned with the taste
of her own pussy and Will's cum who then in turn rolled her head back to
give Will a cum kiss. Will laughed when he realized he was getting a
taste of his cum and Liza's pussy and finished with a yummy hum.

All three snuggled, switching positions, kissing, giggling, running their
hands over their slick and sweaty bodies. They were so lost in the moment
they had no idea what time it was. All three were completely spent. Sarah
suggested that they all hop in the shower together to clean up before
more snuggle time before bed.  As they headed into Sarah's bathroom Liza
looked at Sarah and said, "Mommy, we have to get Daddy to play with us
next..."
