                                 Robert's Thirteenth Birthday Present

	"Daddy, this is the best vacation ever!" Britney squealed.

	"I am glad you are having fun, but it is bedtime right now." I told
my daughter as I pulled the sheet up over her cute little naked ten year
old body.

	Britney, not ready to go to sleep yet, asked, "What are we going to
do tomorrow?"

	That question made my limp dick twitch, but clearing my mind I
answered, "I am going to rent a boat and we are all going over to the
island for a picnic."

	"Oh, that sounds like fun!" She replied as she gave me a hug.

	I gave her a sweet kiss on the lips and sternly said, "Now go to
sleep."

	"Ok. One more child to tuck in and I can finally get to bed." I
said to myself. I walked into my son's room finding him in bed but also not
asleep.

	"Did you ask her?" Robert asked as soon as he saw me enter the
room.

	"No Son. I did not ask her yet. Even if I did I would not have told
you her answer. Tomorrow is your birthday and until then you do not need to
know if you are getting your birthday present from her or not." I
explained.

	With a disappointed look on his face he then asked, "Well what if
she says, 'No?' What happens then?"

	"You know full well what happens. You get your birthday present
from your mother. So, you see, one way or the other your will get your
special 13th birthday present." I told him.

	"Ok." He finally calmed down and said.

	I then pulled the sheet up to cover his naked almost thirteen year
old body. I noticed his dick was now full length so I figured I had better
warn him of the rules.

	"Remember you have to follow the rules. That means you cannot cum
tonight. You have been good right?" I warned with a follow up question.

	"I have been good. I have not jacked off in a month. You know that
was really hard to do." He said with a disgusted undertone.

	I chucked and said, "Yeah. I know it is hard to go a month without
cumming especially at your age but we all have to follow the special rules
for you to enjoy your present.

	Just like Britney, Robert asked, "What are we going to do
tomorrow?"

	I gave him the same answer I gave Britney and said, "I am going to
rent a boat and we are all going over to the island for a picnic."

	With a twinkle in his eyes he asked, "Is that where I will get my
present?"

	"Yes, Son. Now Go To Sleep." I told him with a deep voice.

	He knew when I talked like that he knew it was time to quit, so he
quietly added, "Good night Dad. I love you."

	"I love you too, Son. Good night." I said then kissed him on the
lips with a gentle loving kiss.

	I walked out of the room closing the door. I took a deep breath and
headed to my room. My wife Kathy was already in bed waiting for me. Like
the others, she too, was not asleep yet.

	"Did you have any problems getting the kids to go to bed?" She
asked.

	"Not any more than normal." I admitted. Then with a smile I looked
at her naked body and said, "Now, with the kids in bed let's have some
fun."

	"Hold on there, Buckaroo. You know the rules. I am not allow to
have sex for one week before our son's thirteenth birthday just in case
Britney says she does not want to give Robert his birthday present." She
explained in a teasing manner.

	"Yeah, but..." I begged.

	"No begging. You know the rules. You should. It is your family's
rules anyway. My family had no such tradition. So, just calm down. Did you
ask Britney yet?" Kathy finally asked.

	"No. I will ask her tomorrow." I answered. Then with a stern look
and strong command I said, "Why don't you cover that body of yours up? If I
cannot have your pussy then I really do not want to look at it. Even if it
is the sexiest thing I have seen since I left Britney's room."

	"Thomas!" Kathy yelped. "Britney does have a sweet little hairless
slit, doesn't she?" She giggled.

	By now my cock was at full mast and wanting to expel a week's worth
of cum. I got into bed and covered my body. Turning towards Kathy I kissed
her telling her that I loved her.

	"Is that rod poking me from looking at me or thinking about your
part in tomorrow's adventures?" She slyly asked.

	"Both." I bluntly answered before turning over and going to sleep.

	The next morning Kathy and I were up early. Kathy was making
breakfast and I had headed out to rent a boat by the time the kids woke
up. I returned just in time to eat. The kids were both excited, in more
than one way, and were in a hurry to eat so we could all go to the
island. We all quickly finished eating so we could go have some fun.

	"Britney, go help your mother bring out the food." I told my
daughter.

	While she was inside I took Robert off to the side and said, "When
we get there I am going to take Britney to look around. We will see if
there is anyone else around because if there is then you will have to wait
for your present. I will ask her while we are walking around alone. I just
wanted to let you know why I am taking her and for you to stay with Mom."

	"Ok. I can't wait." He said.

	Britney and Kathy retuned with the last load and soon we were ready
to go. It only took 30 minutes to get to the island but it was a long 30
minutes. Landing at the dock I tied the boat off so it would not go
anywhere and helped get everything unloaded.

	"Britney, let's go see what we can find. Robert you stay here and
help your mother set things up for the picnic." I suggested.

	"Ok, Daddy." She giggled.

	I took her by the hand and we headed out to see what was
around. While we were gone Kathy was going to lay out the blankets and
stuff needed for the birthday party and picnic. We walked down the beach
and found no one around. I then suggested we walk through the woods to see
what was around there too. Still finding no one we headed to the other side
of the beach. Still finding no one around I decided to ask her about
Robert's present on the way back to our spot. Thinking maybe it would be
better to sit and talk I suggested we sit on a bench and have a chat before
getting back. We had always been able to talk about anything so it was not
a surprise to her for me to suggest a chat. For some reason I was having a
hard time getting started but I figured once I started it would flow pretty
easily.

	"Daddy, what's wrong?" Britney asked noticing I was not my normal
self.

	I chuckled and began explaining, "Well, you know it is Robert's
birthday and he is 13 years old today."

	"Yeah. I know." Britney agreed.

	"My side of the family has a tradition for boys on their 13th
birthday. The family gives the 13 year old boys a family present but it is
given to him by his sister. That is as long as she is at least 10 years
old. Robert is 13 and you being his sister and 10 years old will get to
give him the present." I was explaining but not making my point clear yet.

	With a big smile she asked, "Great. What is the present?"

	I smiled back and looking at her very cute hairless pussy I
answered, "Your...um...well. It is your pussy. That is if you say it is
ok. If you do not want him to have sex with you then all you have to do is
say, 'No thank you.'"

	Looking a little concerned she then asked, "What happens if I say,
'No?'"

	"It is ok. Your mother will let him have sex with her." I said.

	Acting a little strange she finally looked at me as asked, "Is that
why he keeps looking at my privates? Ever since we got here a few days ago
I have caught him staring between my legs a lot."

	Chuckling I said, "Probably."

	Britney still trying to figure things out finally continued asking
questions. "Will it hurt? Will he cum inside me? Are you and Mommy going to
watch? When will we do it?"

	"I know this is all new to you so let me explain some things about
the tradition. Then you can decide." I started to say.

	"Ok." She quickly replied.

	"The tradition started many years ago. When a boy has his 13th
birthday he gets to have sex with his oldest sister as long as she is at
least 10 years old. That is why when you turned 10 a few months ago your
mother took you to the doctor. You remember the doctor did something to
your privates? Remember it hurt and there was a little blood?"

	Britney nodded her head, "Yes" as I continued talking.

	"Well the doctor popped your cherry. This was getting you ready for
your brother's penis. If the sister does not want to or if there is not a
sister old enough then the mother takes the place of a sister and the son
and the mother has sex. So you see it is all planned out for all
possibilities." I keep telling about the family tradition.

	Now getting more interested she asked, "What happens then?"

	Being more relaxed I told my daughter, "The next part is where I
come into play. Once Robert cums in either you or your mother, I get to
lick and suck the cum from the pussy until it is all cleaned up. Then the
final part is when I get to cum. I then get to have sex with your mother
while you and Robert watch."

	"Is that the end of it? What if I want more later? And you never
said if it was going to hurt." She continued asking.

	"It will hurt some but since you do not have your cherry it will
not hut as much. I checked his dick and it is only about 4" long hard and
is not real thick yet so it should not hurt much. As for the future your
mother and I will have to see. We will talk about it and will let your two
know what we decide." I answered.

	"Oh. Is that why we looked around to see if anyone else was here?"
Britney questioned.

	"Yes. That is why. Very smart of you to figure that out." I said
with a smile. Then I asked the starting question again, "Would you like to
give him his birthday present?"

	Britney looked at me with her beautiful pale blue eyes and
answered, "Yes. I would like to give him his birthday present."

	She then reached between her legs and rubbed her slit like she was
already excited. I then told her that he would probably not last too long
because part of the rules said he was not allowed to jack off for a month
before his birthday. I also told her that her mother and I was not allowed
to have sex for a week before his birthday which would make it more fun to
have sex in front of them when the time comes. We stood up to finish our
walk back but before we started Britney gave me a big hug. I leaned down
and gave her a gentle loving kiss on the lips which then made her give me
an even bigger hug. We held hands as we walked back to our picnic site.

	Britney and I walked up hand in hand and I thought Robert was going
to come unglued before we could let him know that Britney was going to let
him fuck her virgin pussy. Following the rules of the tradition he was not
allowed to ask or beg in any way. He had to just sit there and wait for his
present and since Britney was going to give it to him it was up to her to
tell him when she was ready.

	"That was fun Daddy." Britney said in a teasing way.

	She knew what her brother wanted to hear and since she was in
charge for the first time in her life she was determined to drag it out. I
looked over at Kathy and gave her the secrete sign to let her know that
Britney was going to let her brother fuck her in the pussy. That way at
least Kathy would know. We all sat there enjoying the beautiful vacant
beach. We talked a little but mainly just sat and looked around. I guess
Britney's pussy was ready or might have been she had relaxed enough to go
to the next step because she stood up and walked over to her brother. She
sat down next to him and kissed him on the lips. He kissed her back but
still did not say anything. I was proud of Robert for being strong enough
to take the teasing Britney was dishing out.

	When Britney was ready she looked at Robert and said,
"Robert. Happy birthday. I hope you like your present from the family."

	She then took his hand and put his hand on her pussy. He looked at
her and smiled. It was funny. He had wanted this time to come for a long
time and now that it was here he did not have a clue of what to do.

	"Robert. I think your sister is trying to tell you that you got
your wish. Would you like to accept the family's gift?" I asked my son.

	Being speechless he just nodded his head, "Yes."

	I chuckled and asked Britney if she was ready. When she said she
was ready I had her lay down. I then helped my son position himself between
her legs. He was stiff as a board and ready to explode. I figured he would
not last long but was hoping he would at least last long enough they could
enjoy the first fuck. I helped him get his dick lined up and told him to
gently push. I watched Robert's cock as he slowly pushed it into his
sister's virgin pussy. I felt my own cock getting super hard as I watched
the show. I almost felt like it was my first time to fuck. Robert bottomed
out with a low moan. Britney was not really in pain but I did notice some
discomfort on her face. I made sure he let her adjust to his dick before he
began to fuck her. When she was ready I told Robert to begin to pump his
dick in and out of his sister's cunt. He started off slowly but soon picked
up speed. Within minutes he was pounding her pussy with a hard pussy
pounding motion. His small marble sized balls bouncing off his sister's
sexy butt.

	Watching him fuck his sister brought back memories of when I fucked
my sister for the first time. My sister was older than Britney was. I got
to fuck a 12 year old for my first sex session. I just hoped Robert was
enjoying his first time as much as I enjoyed my first fucking.

	The longer he fucked the faster he got. It was only about fifteen
minutes of fucking when I heard Britney begin to moan. It was a moan of
love and enjoyment and not a moan of pain. I looked down to notice my dick
was leaking pre-cum by the gallon. I was afraid I was not going to last
long when it was my turn.

	Britney all of a sudden began to loudly moan, "Robert. You feel so
good inside me. Yes! That is the spot. Oh! Oh!! Yes!!! There! Right
There!!! Oh, Oh, Oh."

	That was it. Robert exploded with a double time fuck speed as he
shot his load deep into his cute little sister's pussy. He gave a big grunt
as his load left his dick. They both were panting like dogs in
heat. Eventually they calmed down and began to breath normally. They laid
there still connected as Robert's dick began to go limp. He kissed her,
slipping his tongue into her mouth before they were disconnected.

	Robert pulled his cock from his sister's pussy letting me know it
was my turn. I wasted no time placing my head between my daughter's legs
where I began to lick her bare slit. I licked her pussy lips clean and then
worked my way inside her outer pussy lips. It only took me about five
minutes before I had licked her clean both inside and outside. I kissed
Britney with a loving kiss slipping my tongue inside giving her a taste of
her brother's cum. She looked at me, smiled, and gave me a super hard long
hug before letting me go. I then looked over at Kathy with a lustful
thought and winked at her.

	"Kathy, are you ready to show the kids how we have fun?" I asked
with a look of need in my eyes.

	She giggled from a slight case of embarrassment. We had never had
sex in front of the kids even though we were at a nudist resort and they
had been seeing us naked for days. She got on her hands and knees with her
butt in the air. I knew what this meant and was happy to oblige. She wanted
it doggie style since it was her favorite position.

	I got behind my wife and gently slipped my cock into her already
wet hole. Slowly I pushed my dick in until I was pressed against her
butt. My balls pressed against her butt cheeks as I began to pull my dick
out and push it back in. I did this slow and easy until I was ready to
begin our regular fuck session. I was not only going to give my wife a
pounding to remember but I was also going to put on a fantastic show for
the kids.

	I placed my hands on my wife's shoulders so I could get better
leverage. With everything in position I began to slowly pump my dick in and
out of Kathy's pussy. I could feel her starting to gain more pleasure from
my actions because of the amount of wetness I was feeling on my cock. I
took advantage of the wetness and pumped faster.

	I looked over and saw both children with their eyes fixed on what I
was doing to their mother. Just the thought of my children watching me fuck
my wife was really making me even more excited. I decided to teach Robert
how to make his sister or any other girl he fucked have extra hot orgasms.

	"Robert. Watch and learn. This is how you turn sex into a hot fuck
session." I suggested.

	With the notice I gave my son, I began the show. I pounded as fast
and hard as I could for just about a minute. There was really no certain
time I would do this to start but determined when to change speed by the
moans Kathy would make. When she began to moan I shifted my tactics. I gave
three hard fast pounds of my dick to her snatch. Quickly followed by three
medium speed medium force poundings. Then ending the sequence with three
slow light pumps.

	This sequence of pounds would be repeated over and over and over
for as long as I could manage not to shoot my wad. The longer I fucked her
pussy the louder she moaned. I then shifted and fucked one series of
thrusts from the left then the next set from the right. Kathy's breathing
increased and I could feel her matching my pumps with backwards thrusts.

	"Right there! That is the spot! Fuck my pussy! I am going
to...Oooooooo." She began to scream.

	It was a good thing we were alone on the island. If anyone would
have been around they would be thinking I was hurting my wife. I continued
to pound her as the children watched wide eyed and mouths opened. I was at
the point I was going to cum but wanted to make sure Kathy came first.

	I let out a warning, "I am going to fill your pussy with my hot
seed."

	"Pleaseeeeeeeee! I want to feel your cum splatter inside my hole! I
am going to cum with you. Shoot. Shoot your wad." She yelled.

	I was now over the top and would cum even if I stopped
cold. Knowing this I stepped up my speed and pounded as fast and hard as I
could. I did not even stop after I blew my whole load of cum deep into her
snatch. Then all of a sudden I felt Kathy explode. She spewed her girl cum
all over my still pounding shaft. Still pumping I felt her cum mix with
mine and begin to run down my shaft and to my balls. I began to slow my
thrusts and Kathy's breathing began to return to normal. The kids still
watching as I pulled my still semi-erect shaft from its favorite place.

	"Robert. Britney. Come over here and learn how to clean your mother
up." I demanded.

	While the kids moved over, Kathy turned over and spread her legs so
they could get between her legs. When they were close enough to see I
reached in and pulled her pussy lips apart showing them the inside of her
cunt. I pointed out her clit hood and then pulling the hood back I showed
them her clit. I explained that as they licked her clean they should lick,
suck, and even nibble at her clit and hood. I told them that this would
make her feel good. I also told them that she would put her hands on their
head as they worked her over so she could guide them as to how hard to dig
in. I told them that they should just follow the commands from her sounds
and hand suggestions.

	With the instruction given they began. Britney started and right
off the bat, Kathy started moaning. Her hands clamped onto the back of
Britney's head and she pulled her as deep into her cunt as she could. A few
minutes later I told them to switch so Kathy let go and allowed her son to
dive in. He too licked, sucked, and cleaned her cunt. She was still moaning
but I could tell he was not doing the job that Britney had done. Again I
told them to switch. Kathy was happy to have Britney back and began to fuck
her face with thrusts.

	"Oh! Fuck!" I heard Kathy moan.

	Kathy's body began to shake and her hands pulled Britney's head
hard into her snatch. Britney took that as a sign to work harder. Kathy's
movements and breathing continued to increase until she went stiff and quit
breathing all together. After a few jerks of Kathy's body, she released
Britney's head. Britney pulled back from between her mother's legs. Her
face was soaked. There was pussy cum dripping from her nose, lips, and
chin.

	"Mommy, why did you pee on my face?" Britney honestly asked.

	Kathy looked up at me and I could tell she could not talk. Her
orgasm had taken her breath and left her paralyzed. I knew I was going to
have to explain what happened.

	I chuckled and said, "Your mother did not pee on you. That was
cum. You gave her an orgasm and she blasted your face with girl cum
juice. You should feel pleased that you were able to do that to your
mother." I then looked at Robert and added, "Robert, Lick some of the cum
from your sister's face so you will know what it tastes like."

	He did as I said. Robert then commented on how good it tasted and
that he wanted his mother to shoot some in his face. I told him to get
between her legs and give it a shot. I told him what to do and this time he
listened. He lapped at her clit teasing it with his tongue and even
nibbling at it with his teeth. By now my cock was rock hard once again and
the pre-cum was dripping from my dick head. Kathy began to shake and like
before she tensed up. I told Robert to get ready and just about that time
she blasted off another round of pussy juice. She coated his face just like
she had done to Britney. This time she pushed him away and closed her legs
as she laid back in a ball shivering.

	"What's wrong with Mommy?" Robert questioned.

	"She is having multiple orgasms and until they pass she will need
to just lay there and rest. You might say the two of you wore her out." I
said with a laugh.

	I was now in need of another cum shot myself so I asked the kids if
they wanted to learn how to give a man a blow job. Without even having to
think they said they wanted to learn.

	I told them to climb between my legs and lick my dick like they had
licked their mother's pussy. Instantly they were licking away at both my
dick and balls. They cleaned off all the pre-cum and the cum from the
earlier activities with Kathy. I told them how to slip my cock into each of
their mouths. They took turns licking and sucking my cock head and shaft. I
will have to admit that Britney was better at it than Robert was. It was
not that Robert was not good at it but there was just something about
Britney's 10 year old mouth that my cock just adored. I got really close to
cumming about the time they were to switch. I, on the other hand, wanted my
first shot to be in Britney's mouth so I held her head next to my body
until my first shot penetrated my pee hole and spurted out into her loving
mouth. Not wanting Robert to be left out I pulled my cock from Britney's
lips and pulled Robert close enough that my next squirt splattered on his
cheek. I moved back and forth until both children were covered with my
white yummy cum. I told them to lick each other's face until my cum was
cleaned up.

	I looked down and saw that Robert was again hard and ready to be
milked again. I suggested that Britney should get more practice. I told her
to lean over and suck her brother's dick until he came down her
throat. Without question she began and in just a few minutes he was getting
ready to expel his load down his sister's throat. I told her to see if she
could drink his whole load without spilling a drop. I knew since he had
already cum once it would be easier but then I also knew he had only cum
once in the past week so he was still going to cum a lot. I told Robert
that while she sucked his cock to finger fuck her pussy. This would benefit
the both of them. I showed him how to finger fuck his sister as she sucked
his cock.

	They began and in just a few minutes he blasted his second load of
the day down her throat. She was perfect and without missing a beat or
dropping a drop she gave her brother an exceptional blow job drinking his
entire load. She to experienced a baby orgasm from the fingering her
brother was doing.

	We laid in the sun and rested for the next hour or so. When we were
finally able to move around we had our picnic before packing everything up
and heading back to the room. I returned the boat as the others put things
away.

	Kathy and I took a shower together while the kids rested. I then
had Robert and Britney shower together while Kathy and I talked about how
we felt about what happened. We decided that we were going to be an open
family and would allow sex as long as no one outside the family knew and
that everyone was agreeable to the idea. When they returned from their
shower we talked about the new decision but I knew there was something
funny about the way they were acting. Come to find out they had just had
sex in the shower even before they knew it was alright with Kathy and
myself.

	Over time we all had sex with each other both as a group and
individually. Kathy loved the oral sex that Britney was able to perform on
her. I loved Britney's pussy and was finally able to fuck her a few years
later. Robert found he loved fucking his sister and my asshole equally and
Britney loved sex with everyone. We even set up family night and once a
month we had group sex where we played a game that randomly decided who
fucked who in what hole. Just think, all of this came to pass just because
of a family tradition. You just never know what could happen when
traditions are followed to the letter.

                                             The End
