 When I was Thirteen

   I just had my 13th birthday when mom came into my room and found me
masturbating.  I tried to cover up but she saw everything.  I was so
embarrassed.  "Johnny," she said, "that's not anything you should be
embarrassed about.  It is perfectly normal for boys and girls to
masturbate. I'm sorry I barged in without knocking first.  I'll try to
remember."

   Johnny really wasn't that embarrassed.  He was more startled than
anything.  His real desire was to see a girl naked other than his sister,
Marcy.  She is 9 and a real tomboy.  She doesn't have any boobs yet and she
is built like a stick with lanky legs, no waist to speak of and a boy's
butt.  She loves to wear boy's shorts and tee shirts even though mom tries
to dress her in dresses or skirts and pretty blouses.

   I rummaged through her drawers once and found she wears soft cartoon
panties with thin elastic and they are cut way different than my briefs.  I
also rummaged through mom's drawers and found hers.  She likes even thinner
ones and only has a patch of material in front.  The rest is really just a
thin ribbon to hold them up.  The elastic is very narrow too.  Dad doesn't
wear briefs.  He wears shorts under his clothes.  They are all different
colors and patterns, some plaid and some striped and some are just plain
solid color.  They have a slot in front so he can pee without removing
them.

   A few days after mom caught me masturbating she said at dinner, "Mrs. 
Jones asked me if you would like to babysit for her sometime?  I told her
you had never done that except for your little sister.  I said I would ask
you if you wanted to."

   "Mom, Johnny's a good babysitter.  He always played games with me when I
was little and he tucked me in bed really good." Mary said.

   "Mom, I'd like to babysit for Mrs.  Jones sometime.  It would give me
some money to buy things.  Besides, Betsy and Billy are neat kids." Johnny
said.

   "OK, I'll call her tomorrow and let you know when and such." Mom said
with a smile.

   That night I lay there in bed wondering how babysitting would really be.
Would I get to bathe them or dress them would they already be ready for bed
when I got there?

   The next day after school mom told me that the Jones' were going out of
town Friday evening and wouldn't return until Sunday morning.  I told her
that we would check on you and her kids and that you would call me if you
had any problems.  She said she would pay you $50 for the weekend.  That's
a lot of money for a boy your age.

   My grin was from ear-to-ear as she told me all of this.  I definitely
would do a good job babysitting.

   "Mom, how old is Betsy and Billy?" I asked.

   "Ummmmmm Billy is 6, I think, and Betsy is 8 maybe 8 ½.  Why?"

   "Oh I was thinking about what kind of games we could play and maybe go
to the park."

   "Johnny, that's a big boy to be thinking about how to keep them
occupied. They will like the park and maybe even swimming.  I'll pack your
swim suit and some other clothes." Mom added.

   "Mom, I want some big boy undershorts, not the kind I have now.  Could
we get me some like dad wears?" I asked?

   "Sure, I'll see if your dad will take you shopping tonight.  It'll be
good for both of you." She said.

   Dad took me shopping and we had fun.  We always have fun when he gets a
chance to relax from his work.  We talked about all sorts of things and he
even mentioned babysitting would be fun for me as it would prepare me for
when I have kids of my own, especially when they don't want to mind.  Dad
and I shopped at a sports store and I got a new swimsuit, one of those
Speedo racer styles in Bright Red just like our school swim team wears. 
Then we went to a department store in the mall and looked at shorts,
underwear and undershirts.  Dad had to have the saleslady measure me to be
sure I got the right size since dad doesn't usually buy my clothes.  I got
three packages of undershorts in various patterns and colors and a package
of tank tops.

   Mom washed everything before she would let me wear any.  That night
Marcy sneaked into my room.  I think she was curious all of a sudden.  I
usually sleep in briefs but tonight I was butt naked.  I had been stroking
my penis and it was fully hard.  I am about average in penis size, at least
from what I see in the locker showers at school.  I have very little hair
around my penis but what is there is very soft and silky.

   Anyway, Marcy came in and crawled into bed with me.  She snuggled up to
me and hugged me as she said, "Johnny, are you gonna have fun with Betsy
and Billy?"

   "Ummmmm, I hope so.  I hope we can play games together and maybe go to
the park and swim."

   "Can I go swimming with you if you take them?" she asked.

   "Sure, sis, but only if mom says its ok.  I have to watch them and I
don't know if they swim that well or at all, so you'll have to stay close
so nothing happens to you." I said.

   She suddenly realized I was naked and she cuddled closer.  My penis got
hard as she spooned into my back.  I really wanted to see her naked now and
do things with her but I didn't know what or how.

   "Johnny, Why are you naked in bed?" she whispered.

   "I sometimes like to sleep naked.  It's cool to my skin and I like it."
He answered.

   "I like feeling your skin too." She commented.

   On hearing that Johnny turned to face her.  She felt his hard penis
poking her.  "Johnny why is your thingee stiff?" She asked.

   "It sometimes gets that way.  I don't know for sure but you being here
hugging me doesn't help keep it soft." He added.

   She started to move away from him when he leaned in and kissed her on
the lips.  It was just a little kiss, nothing like a lover would kiss his
girl but it took her by surprise.

   "That was nice Johnny, but why did you kiss me?"

   "I love you sis; always have."

   "I love you too though sometimes you're mean to me."

   "Sorry sis, I'll try not to be mean again.  Now I think you better go to
your bed before you fall asleep and mom finds you here in the morning."
Johnny told her.

   "OH alright, but kiss me again." She said.

   Johnny kissed her once more on her lips and this one lingered a bit
longer then she got up and went to her bed.

   Friday came and Johnny was looking forward to the weekend with the
Jones' kids.  When he arrived, Mrs.  Jones showed him the book with all of
the phone numbers and the permission slips for him and his parents should
the kids need medical attention.  He hoped that wouldn't be necessary.

   Betsy and Billy were very anxious to playing in the backyard.  Johnny
pushed the swing for them and they kept yelling "Higher" on each swing
push. Johnny could see Betsy's panty each time he pushed her and it was
pink.  He could see the red lines caused by the seat on her thighs too.  He
was getting turned on by this sight.

   Pretty soon they wanted to go to the park but Johnny said they could do
that tomorrow.  They settled down to playing in their playroom.  Billy took
his shorts off and was only in his briefs then Betsy took her dress off and
was only in her panty.

   After their dinner, it was bath time.  The kids wanted Johnny to bathe
with them so he decided that might be nice.  He ran the water in the tub to
the right temperature and added some bubble bath and toys.  Both kids
stripped naked and climbed in.  Johnny got a full view of Betsy's open
cleft as she got in.  He stripped naked too and climbed in.

   Betsy paid him no mind since she is around her brother all the time. 
There was lots of touchy feely as they played with their toys.

   He had Billy stand so he could lather him up and wash him.  When Billy
stood his little penis was fully hard and the head poking out of the
foreskin.  Betsy noticed this and reached for it to play with it.

   Johnny watched as Billy stuck his hips out anticipating her touching
him. She took hold of his penis and lightly stroked it back and forth. 
Billy gave out some mewling sounds since it was pleasureful for him.  Then
Betsy leaned closer to him and took his penis into her mouth.  He put his
hands around her head as she had him fully in her mouth.

   Johnny didn't know what she was doing but Billy seemed to like it as he
was jerking back and forth as she ministered to him.  He wondered just what
that would feel like and then wondered if his sister would maybe to that
for him.  He dearly loved his sister and she liked being with him in bed
especially when he was naked but they had not engaged in anything like
this.

   A few minutes later they both stopped and she just held him in her
mouth. He told her he loved her and she then slipped off his penis.  It was
still hard so Johnny put some soap on his hands and began washing him like
he washes himself.  It must have been very sensitive since Billy yelped,
"It hurts!"

   Johnny rinsed him off and then helped him out of the tub.  He handed him
his towel so he could dry himself.  Then he stood Betsy and gazed at her
little split.  It was a bit puffy and inviting.  Since it was already close
to his mouth he leaned forward and gave it a little kiss.  She giggled that
it tickled so he did it again.  Then he stuck his tongue out and gave her a
lick.  She giggled even louder but didn't pull away.

   Johnny had discovered something that felt good to her.  He continued
licking and gripping her little butt as she pushed herself closer to him to
give him more contact.  She really liked it as she gave out a moan now and
then.

   Johnny's penis was now very hard and stiff.  He wondered why since he
wasn't playing with it.  A few minutes of licking her and she relaxed and
leaned onto his shoulder.  He caressed her and kissed her then whispered
that he needed to soap her and wash her.  She let him.  As he got his knees
to wash her face she saw his hard penis.  She reached out and touched it
like she had her brother's and Johnny flinched at her touch.

   It was a tender touch and he liked it.  He whispered to her to be
careful as it might shoot out his semen.  That was new to her since Billy
didn't do that.  She continued playing with him as he finished bathing and
rinsing her with the hand shower.  He then opened the drain and as the
water gurgled as it drained away he lifted her.  In doing so she hugged him
close.  He then stood up with her in his arms.

   He stepped out of the tub holding her close.  His penis was hard and
poking at her virgin split.  It felt good to him and apparently to her as
she pushed it to make it feel good to her.  He then dried her off with her
soft towel.  She loved his attention to her nipples and he girl parts.  He
kissed her when he finished and helped her put on her little nighty.

   Billy, meanwhile, watched as his sister and Johnny played with each
other.  "Sissy, can I sleep with you in your bed?" Billy asked.

   She smiled and said he could.  Johnny helped Billy into his shorty
pajamas noticing his penis was still very stiff.  They led him to her bed
and she crawled in followed by Billy.  Johnny, still very naked, knelt
beside the bed and had them say their prayers then gave each a love stroke
on their chests and sex parts.  Billy snuggled up to his big sister and
kissed her then fell asleep.  She was holding his penis as she too fell
asleep.

   Johnny put out their bed lamp and went to the bathroom to clean it up
and finish his bath.  He took his time being sure to get himself feeling
good by masturbating.  He shot his semen into the tub and then rinsed off.
Then he dried the wet floor with a towel and put on his shorts.  Satisfied
everything was in order he went to the den to watch TV and nap.

   It was well after midnight when the Jones' returned home.  Mrs.  Jones
noticed that Johnny was lying on the couch and his penis was outside his
shorts and he was holding it.  Mr.  Jones thought it was cute and said, " I
guess he had fun with Betsy and Billy.  I wonder what really happened." He
said to no one in particular.

   "I don't know," Mrs.  Jones said in reply, "but I'll go check on them."
When she went in to Betsy's room she saw her two snuggled together and
Betsy holding Billy's little penis.  It was now very soft and both had
little smiles on their faces.

   "I think they are happy." She said.  "Billy has his arm over Betsy and
she is holding his little penis.  I doubt anything else happened that we
need to be concerned about.  I will watch them over the next few days and
see if there is anything to be concerned about.  I wouldn't worry too much.
Johnny is a young teen and curious about his sexuality and Betsy is
beginning to be interested in her body too.  I suspect they have played
some games like 'show me yours and I'll show you mine.' It's normal, heck I
did that with my brothers too."

   Over the next couple of weeks all of the kids acted normal.  Neither mom
noticed anything different with their kids.  Johnny was even left alone on
a Saturday night with his sister.  Mom and dad never guessed what all they
did but Johnny and Marcy learned a lot about each other's bodies.

   It began just a few minutes after their parents left for their night
out. Johnny told his sister he was going to take a bath and left her to get
a game ready for them to play when he got cleaned up.  He got his shorty
pajamas and stripped to his boxers and went to the bathroom.  He and his
sister share their bath with each other.  They used to bathe together but
after he got caught masturbating in front of his sister as their bathed
last year, mom made them bathe separately.  She told them they both needed
their private time and that they were getting too old to bathe together.

   One thing Johnny knew was that was not true since he had caught them
bathing, showering together often.  And the sounds he heard were different
from he and his sister sounds.  He thought they kissed a lot but he wasn't
sure.

   Johnny had just stripped naked and was stepping into the tub when Marcy
came into the bathroom.  She saw him naked for the first time in a long
time and felt tingly in her pussy.  It was a new feeling for her, one she
seemed to like.  "Can I bathe with you Johnny?" she asked.

   "Sure sis, Mom isn't here and I'd like that.  You get ready and I'll add
more hot water and some bubble bath to the tub." He said.

   Marcy ran to her room throwing her clothes off as she went.  She was so
happy.  She and her brother were going to bathe each other.  It was only
few minutes later that she nakedly ran back to the bathroom and stepped
into the tub with Johnny.

   He took note of her young body.  It was more developed than Betsy's. 
Her split seemed more puffy and when she spread her legs as she stepped in
he could see deep into her.  He could see the hole where he thought his
penis would go but he wasn't sure.

   She settled into his lap as he put his arms around her.  She could feel
his hardening penis as it got situated in her cleft.  He hugged her close
and then kissed the back of her neck and her earlobe.  He inadvertently
found one of her sensitive erogenous zones and she clasped his hands to her
chest.  He could feel some softness under her stiff nipples.

   He began washing her with the liquid soap she used.  It was very soft
and slick on their skin.  He liked it and hoped she would use it on him. 
He washed her little chest and then had her stand as he washed, caressed
and fingered her little butt and between her legs.  He took the hand shower
massager and rinsed her even putting it on fast pulse and aimed it at her
virgin hole.  She almost collapsed on him as she orgasmed, though she
didn't know what it was.  He kissed her and then he gave her pussy cleft a
lick just like he did with Betsy.

   "Oh Johnny!" She exclaimed as his tongue flicked across her immature
clitty.  "Oh, Oh, OH...." She moaned as he delved deeper into her.  "Don't
Stop Johnny.  OH my that is so good." She kept moaning.  She kept jerking
and thrusting her hips as he now tasted her girly flavor as she began
seeping her fluids.

   It tasted so good to him that he soon realized he had his middle finger
embedded to the first knuckle in her butt hole.  She was thrusting back and
forth, first her pussy then her butt was getting massaged and felt up.

   She was gripping his shoulders and moaning, throwing her head back and
mewling with pleasure.  A short time later it was too much and she slipped
from his grip and fell down onto him.  His now hard penis was standing
proud as she fell and the mark couldn't have been better.  She fell
directly onto his cock and tore her virginity as his over 4 inch penis
penetrated her vagina to the hilt.

   "AIIEEEEEE" she screamed as the instant pain hit her brain. 
"OHHHHHHH.....GODDDDDDD....  IT HURRRTTTTSSS JOHHNNNYY." She screamed but
didn't try to get off.

   "Take it out..!  Please!" She yelled.

   He tried to reposition her but she was now sitting full onto him and he
got a flushed feeling of pleasure as he felt his cock swell and felt the
heat of her tight passage.  "Ahhhhhhhh" he moaned as he blasted her young
pussy with his semen.  It was the most glorious feeling for him in the
world.  He had never felt that wonderful in his young life.  It was like he
had died and gone to heaven.

   He found her lips and began kissing her.  It was not a sisterly kiss
either.  It was an totally adult, wet, sucking, tongue lashing kiss.  His
brain was now overwhelmed with the sensations he was feeling.  He felt her
relax in his arms and give herself to him totally.  She sighed heavily as
the initial pain was overcome by the most pleasant feeling she had ever
felt.

   She felt his fullness inside her.  It seemed to fill her to capacity and
then she felt his penis twitch inside her.  "OH Johnny...  Don't stop... 
Don't take it out...  Push it deeper..  Oh honey ...  feels....  So ... 
good..." she suddenly whispered.  She now threw her arms around him and
squeezed him and then tried to raise up to get a better position.  As she
did he thrust up once more..  She dropped down again on him.  His penis was
now fully hard and as big as it could ever be.  He didn't know it but it
was now 5 inches long and resting on her cervix opening.

   They sat that way for several minutes each lost in their own thoughts
and pleasure.  He spewed another shot of his now virile sperm into her. 
She and he suddenly realized just what they were doing and knew it was the
beginning of a loving friendship not usual for brother and sister.

   "Marcy, I'm sorry if I hurt you..." he began acting guiltily.  "Oh god
your pussy feels so good.  I could stay in there forever." He said.

   "Oh I know Johnny.  I never thought we'd do this.  I can't stop moving
on you.  I felt some hot wetness..  What did you do in there?" she asked.

   "I think I spurted my sperm inside you.  Sperm is what makes babies in
women and girls if they are fertile." He said.

   "What's fertile mean, Johnny?"

   "It means when you have your monthlies, you know, like bleed every month
or so.  They told us in sex-ed that girls have eggs in their bodies
produced in their ovaries and when they get old enough a mature egg gets
into her tubes and if sperm join with the egg she can get pregnant and then
have a baby." He explained.

   The whole time he was explaining she was fucking herself on his penis.
"Oh, Johnny, I've not had any bleeding so I hope that is a good sign." She
said.

   "I think it is.  But, I think you should get off of me now.  My legs are
going to sleep and we need to finish bathing." He said.

   "OK but I want us to do this again on a bed or the floor.  I loved
having your penis inside me.  It felt so natural." She said.

   As she got up his penis slipped out followed by a flood of pink blood
and semen mixed into the bath water.  "Yuck" he said as he saw that.  He
splashed water onto her pussy and washed it away at the same time he rubbed
her naked pussy.

   "Oh Johnny...  That feels so nice."

   "Really sis, All I'm doing is washing your...  your...  pussy."

   She stood up and then helped her brother stand.  She is a full head
shorter than him but she stood on tippy toes and kissed him.  He leaned
down to accept her kisses.  She also felt his cock that was now only half
hard.

   They finished their bath and dried each other off.  There was constant
chatter between them as they gathered up their clothes and put them in the
hamper.  He took her hand and led her to his bed.  His bed is a full size
double bed and would give them lots of room for what he had in mind.

   He got her on her back in the middle of it and spread her legs as wide
as possible.  He looked into her gaping pussy.  It was all pink and red
from their previous activity.  He leaned down and licked her once.  She
grabbed her ankles as Johnny buried his mouth onto her open pussy.  He
stuck his tongue into her cunny hole and licked all around the edges.  She
was moaning and crying in pleasure as he brought her to one orgasm after
another.

   Meanwhile his cock had regained it hardness.  He wanted to bury it once
again into his sister.  He leaned up to kiss her.  His cock found her
wetness and the slot just as he got her lips against his.  He thrust, or
rather fell, into her formerly virgin hole.  She swooned again as her
nerves overtook her brain.  She shuddered in silence as he pounded in and
out of her tightness.  He was a raging bull now deeply banging her cervix
and his balls were slapping her anus.

   Though he had the speed of youth his endurance was short lived.  He
collapsed onto her.  His penis flexed and twitched inside her as the last
shots of his sperm bathed her cervix.  He didn't realize just how lucky he
was that she was pre-pubescent or she would have been knocked up many times
over by the amount of sperm he shot into her.

   She had fainted and was out of her mind as he too fainted in lust onto
her.  They both awoke about the same time.  She just hugged him close as he
wiggled and flexed his cock inside her love chamber.  They kissed lip to
lip not as brother sister but as lover to lover.

   Mom and dad found them in that position when they returned home.  There
was no doubt that they had made love and that a culmination had occurred.
Mom could see his sperm crusting around Marcy's vagina and his penis was
still lodged fully in her.  It was the most erotic scene their parents had
ever seen.  Dad took mom in his arms and then led her to their lair.  There
was no foreplay between them as Dad just thrust his 8 inches fully in to
his wife of 13 years.  He cared not whether she was fertile or not.  He had
his way with her as he did on their wedding night when they conceived their
son.

   When they all awoke the next morning they both hoped that only mom had
conceived this time.  Marcy would be taken to the doctor to get her on
birth control since they both knew there would be no keeping them apart.

   The following week Mrs.  Jones and Johnny's mom were talking privately.
Johnny's mom told her about finding her kids locked in loving embrace and
that Marcy was now protected.  Mrs.  Jones said she noticed her two were
more loving and suspected they too were sneaking bedtimes together.

   Mrs.  Jones said that Betsy had asked when Johnny was going to babysit
them again.  The women agreed to let him babysit her kids.  If there was
that trust between the kids and love then let them be kids.  Mrs.  Jones
assured Johnny's mom that Betsy was too little to have a baby so no
protection would be needed.  She did say she would keep an eye out and hope
that her son would find his sister to be his lover in a year or so.

   So it was at thirteen, I, Johnny, lost my virginity and caused my sister
and neighbor girl to lose theirs within weeks of each other.  My sister and
I graduated together: she from high school and me from university.  She was
pregnant by me on her graduation, but she married her boyfriend who thinks
it was he who knocked her up and now she is pregnant with a little girl by
him.  I married Betsy when she graduated high school a year later and now
she is pregnant.  We don't care what sex the baby is so it is still a
mystery to me.
