     This was the opportunity 27-year-old Tammie had been waiting 
for.  She'd come home early from work and, while walking by her 
13-year-old son's room, she saw him masturbating through the 
partially open door.

     It had been such a long year since Jimmy's father had died, 
such a long time since she'd had a big, stiff dick.  Her pussy 
started juicing even before she slid a hand up her skirt and 
started fingering her moist slit and clit.

     "To hell with mourning any more," thought Tammie.  "It's 
time I got some of what *I* need.  Besides, he's going to need 
more practice than just the little he got last year, before he 
shows his sisters how."  Throwing caution to the wind, Tammie 
rapidly undressed just outside her son's door, and stepped into 
the room.

     "I know something that'll feel much better than your hand," 
she said; eyes twinkling, as she watched Jimmy's stiff 8-incher 
rapidly wilt.

     "Geez, Mom!" Jimmy yelled.  "Can't a guy have a little 
privacy around here?" he asked.

     "I'm sorry, Honey," Tammie said apologetically. "But it's 
been so long since I've even SEEN a good stiffy! Besides, I've 
been meaning to talk to you for a while," she said; stroking her 
son's hardening cock.

     Taking a cue from his mom's actions, Jimmy slowly started 
exploring his mother's body, as she sat naked beside him on his 
bed.

     As her son started fingering her juicy pussy, Tammie started 
moaning, "Oh, yeah! That's good, honey."

     "As I was saying," Tammie continued, a bit breathlessly.  
"You know how this family has certain, um ... traditions. Since 
you're the man of the family now, it's your duty to take care of 
certain ... things. Its time you took care of one of those 
traditional responsibilities."

     "You know how I took your cherry on your 12th birthday last 
year?  Well, next week is the twins' 12th birthday; and as the 
man of the house, it's your responsibility to make women out of 
your sisters.... And as your mother, ('Not to mention a horny 
woman,' Tammie though to herself.) I feel it's my job to make 
sure you know what you're doing.... Just so you don't 
accidentally hurt your sisters..."  Tammie moaned softly, as she 
moved to impale herself on her son's fleshy pole.



                                1


     "Oh, Jimmy!" she cried. "God!  I wish I'd gotten up the 
nerve to have this talk with you earlier!  I haven't felt this 
full since I lost your dad!"

     "Oh, mom!  You don't know how long I've wanted you like 
this, how long I've been fantasizing about this....  Ever since 
that first time, I've been wanting to do it again," Jimmy moaned.

     "Oh, Jimmy!  I'm sorry.  It's just that your father and I 
were so close; I couldn't just start fucking you right away.  
We'll make it up.  Now fuck your horny mother!  Knock her up, 
like you're gonna do your sisters!  Give me your baby!  I wanna 
feel my handsome son's baby inside me!" Tammie cried.

     "Oh, mom! I'm cumming inside you," Jimmy groaned, as his 
mother's vagina squeezing on his engorged prick, and the thought 
of planting a baby in his own mother's womb almost drove him over 
the edge.

     "Cum in me baby!" Tammie moaned; trying to encourage her 
son. "Fill Mommy's pussy with your nasty baby juice!"

     His mother's dirty language was the last straw.  Jimmy could 
feel what seemed like a gallon of cum racing out of his balls 
into his mother's juicy cunt.  The oversexed boy could feel 
himself almost lose consciousness from the sheer pleasure of 
sending bolt after bolt of thick creamy cum splashing into his 
mother's receptive womb; while he heard her gasping for breath in 
her own orgasm.

     Later, while the two incestuous lovers lay enjoying the 
afterglow of sex, Tammie giggled.  "Well, I can see you'll be 
able to take good care of your sisters!" she observed slyly.

     "Yeah, I have to admit, I've noticed how they've started to 
'bloom,'" Jimmy said.  "And they've been trying to sneak a peek 
at me in the shower lately," he added; smirking.

     "Hmm... I can see YOU find the idea of fucking your little 
sisters exciting," Tammie laughed while fondling her son's 
rapidly inflating dick.

     "Yeah -- almost as exciting as fucking my own mom," Jimmy 
replied, flexing his dick in his mother's gentle grasp.

     "Well, I've GOT to take your cock!  I just love sucking on a 
stiff one like yours, Jimmy," she said as she rolled over and 
started sucking her son's cock.  It had been so *long* since 
she'd had a good prick to suck on.  Tammie was enjoying herself, 
for the first time in almost a year.

     "Mmmm...Oh, that's good, Mom!" Jimmy moaned.





                                2


     "Mmf.  Yeah.  It tastes sooo good!  Especially with our cum 
all over it!" Tammie said; smacking her lips at the delicious 
taste.

     "You keep that up, and I'll be cumming any minute now," 
Jimmy observed. "And I'd hate to waste my cum where it won't do 
any good...," he finished, with a grin.

     "Ooh, yeah.  Give it to me doggie-style this time!" his 
mother moaned.

     "OK, Mom. You asked for it.  Take my big baby-maker up your 
juicy pussy! I'm gonna knock you up so good our kids'll have 
kids!" the incestuous mother-fucker said; as he filled his mom's 
spasming cunt full of his incestuous cum.  Such a sexy thought, 
making babies in your own daughters.  Well.... Maybe someday.

     --

     The next week, after her daughters' 12th birthday, Tammie 
called the girls into her bedroom.

     "Girls, it's time for you two to become women.  Your brother 
tells me you've been trying to peek at him in the shower, so I 
know you're curious.  Normally, your father would be the one to 
teach you about sex and how to make a baby.  But since the 
accident, your brother is taking over as the man of the house.  
Jackie, Jenny:  James is going to make women of you two tonight.  
So I want you both to get naked and lie down on my bed here," 
Tammie said.

     The two girls quickly complied; giggling nervously.  Their 
parents had never kept sex a secret; so they both knew what was 
involved in "becoming a woman" and how babies were made.  Still, 
they had never really believed until now, that their own mother 
would have their big brother be the one who showed them how.

     James walked in sporting a hard-on; boldly walked over to 
the two girls and asked, "OK, who's first?"  He figured he might 
as well be up-front about it.  If his little sisters wanted to 
find out about sex, then he was just the man to show them.

     Jackie and Jenny looked at each other for a moment; until 
Jenny said, "I wanna go first."

     "OK.  Spread your legs, and let's get started," Jimmy 
instructed; feeling both nervous and excited himself; having 
never fucked a virgin before.

     "Eat her out first; and get her good and juicy," Tammie 
suggested.  "Then, just before she cums, pop her cherry."






                                3


     "OK, Mom.  That's a good idea.  I guess she won't feel it 
quite so much when I pop her cherry," Jimmy said; as he knelt 
between his 12-year-old sister's thighs and started eating her 
hairless pussy.

     "Ohh! Jimmy.  That tickles funny!" Jenny cried. "Please keep 
licking my coochie," she squealed; thrusting her crotch up at her 
big brother.

     "A *woman* calls it her pussy, Honey," Tammie said.

     "Oh, Jimmy, lick my pussy!" Jenny wailed; as she squeezed 
her brother's head between her thighs.  "Oh, oh, oh - Jimmy!" 
Jenny panted.  "I feel funny."

     Taking that as his cue, Jimmy placed the head of his 8-inch 
'monster' at the opening of his sister's virgin pussy, and rubbed 
it up and down a couple of times; thereby making sure it was good 
and lubricated.  Then the boy pushed his cock into his sister's 
pussy; burying himself about halfway in and popping her cherry.

     "Oh!" Jenny cried; her eyes suddenly going wide-open. 
"Aaaaah!" she wailed; wrapping her arms and legs around her big 
brother as she climaxed.

     James gritted his teeth, trying to keep from cumming before 
he got all the way into his little sister's sucking young pussy. 
Slowly fighting his sister's spasming  cunt and her legs clutched 
around his back; he pulled himself back out halfway, then buried 
himself to the hilt in the 12-year-old's orgasming pussy.  Unable 
to hold out any longer; he felt his balls tighten as he pumped 
what felt like a quart of incestuous sperm into his little 
sister; while their mother and her twin sister looked on with 
interest.  It was so exciting to watch the 13 year old boy try to 
impregnate his own little sister.

     "Am, am I a REAL woman now?" Jenny asked, as she came down 
from her first orgasm; her pussy still spasming around her big 
brother's cock.  "When can we do it again?" she continued. "I 
*like* it!" she said tiredly, with a smile on her face.  Feeling 
her brother squirting his cum inside her had been a thrill like 
none she had ever gotten before.  Not with her own fingers, or 
even with her twin sister.  She resolved that she was going to be 
feeling this wonderful sensation a *lot* more in the future.

     "Technically, you're a woman, since Jimmy fucked you and 
came in you.  But in this family, you don't get all your rights 
until after you've had your first baby," Tammie explained.  "I 
know you two've been having your monthlies for some time now, so 
Jenny may already be pregnant now.  However, you should keep 
'practicing' making a baby with Jimmy, until you get it right, 
and stop having your period.  Same goes for you, Jackie," she 
said.

     "Gee, mom.  I dunno if I can do Jackie right now.  Jenny 
really took a lot outa' me," Jimmy said; sounding tired.

     "But that's no fair," Jackie cried.  "I wanna be a real 
woman too!!"

     "Well, then:  You're just gonna' have to help Jimmy get 
ready," Tammie told her.

     "What do I do?" asked Jackie.

     "Take your brother's cock in your mouth; and treat it like a 
Popsicle or ice-cream cone -- lick it and suck it," her mother 
instructed.

     "But, but.... He just had it inside of Jenny.  Shouldn't he 
wash it first?" Jackie asked.

     "No, Honey.  That just makes his dick taste even better.  
See?  *I* don't mind," Tammie said; taking Jimmy's bloody cock in 
her mouth.

     "Oh, mom!  That feels great," Jimmy said; moaning in 
pleasure.  "Hey, Jackie.  You try it.  Just remember: If you bite 
it off, you won't be a real woman," he said, jokingly.

     Jackie stuck her tongue out at her big brother and said, "Of 
course I won't bite.  I can't WAIT for my turn."

     "Oh, yeah, Sis.  That's it.  Suck me good.  Yeah," Jimmy 
chuckled.  "You're a real natural little cock-sucker aren't 
you?!"

     When Jimmy started to pull his dick out of her mouth, Jackie 
started to protest.  "Why are you pulling it out??  It tastes so 
good.  I wanna keep sucking.  I thought you LIKED having me suck 
on your dick.  Am I doing it wrong???" she asked, in confusion.

     "No, silly.  You were doing it great.  But you want to 
become a REAL woman don't you?" Jimmy replied.

     "OK," Jackie said agreeably; lying back and spreading her 
legs for her handsome big brother.  "Make me a real woman!!"

     Jimmy was going start out by eating his sister out, but when 
he noticed she was already juicy from watching him fuck her twin 
and sucking on his dick, he just rubbed the head of his dick up 
her hairless slit a couple of times, and plunged right in.









                                5


     "Oh, Jimmeeeeee!" Jackie wailed as the combination of 
pleasure and pain drove her over the edge into orgasm.  She 
hadn't really expected to cum the first time; knowing that it 
would hurt.  But the knowledge that it was her own big brother 
whom she loved so much, driving his thick baby-making penis 
inside her tight little slit, where no man had ever been, was too 
exciting for the young girl.  Her tight little pussy milked and 
squeezed on her brother's prick; trying to milk his incestuous 
cum inside her belly, where it belonged.

     Jimmy pulled out slightly and started to really fuck his 
dick in and out of his sister's orgasming pussy.  Despite having 
cum only a few minutes before in Jenny's pussy, Jimmy could feel 
the pressure starting to build in his balls again; and knew he 
would soon be filling the child's womb with jet after jet of 
incestuous baby-making sperm.  He was going to do it right, and 
let his little sister have it all.

     Jackie barely managed to stay conscious, as Jimmy's pile-
driver dick kept ramming in and out of her freshly deflowered 
pussy; sending her into wave after wave of orgasm.

     Finally, Jimmy couldn't take the frantic squeezing of his 
little sister's tight pussy any more, and dumped a huge load of 
cum in his little sister's ripe womb.  Squirt after squirt spat 
out the head of his prick, and into the warm recesses of his own 
little sister's welcoming young womb.

     "Oh, Sis.  I'm cumming," he groaned.  "I'm making a baby in 
my own sister.  Oh, Jackie. Feel the baby-juice shooting in you?  
Oh, baby, take it!" Jimmy cried, as he collapsed in orgasmic 
bliss on top of the gasping little girl.

     "Oh, yes, Jimmy.  Make a baby in me.  Make me a real woman" 
Jackie cried.  "I'm gonna have your babyyyy..."  She couldn't 
believe how good it felt.  It had been exciting, when her brother 
had just been fucking her.  But when she felt the older boy 
stiffen on top of her, and knew he was sending jet after jet of 
incestuous baby-making cum squirting into her unprotected uterus, 
the little girl knew that everything before had just been a 
build-up.  "There's nothing like knowing your own brother loves 
you enough to let you carry his baby," she thought, as she worked 
to strip the last precious drops of Jimmy's sperm into her no-
longer-virginal young slit.

     A few minutes later, Jimmy woke to someone sucking his cock.  
It was his mother.  He could feel his dick starting to get hard 
all over again.

     "Mommy's turn, baby" Tammie cooed.  "Make a baby in me like 
you did your sister, and maybe it'll be another little girl for 
you to fuck!" she moaned.





                                6


     Well, after leaving two generous helpings of incestuous cum 
inside his little sisters, it took a little longer for Jimmy to 
work up enough sperm to impregnate his mother as well.  Still, he 
was young, and it didn't take all *that* long, before he was 
filling the older woman's womb with his seed, just like he had 
done with her daughters.

     As you can imagine, no one got much sleep that night.  With 
three horny, fertile females, and one oversexed teenager, it 
didn't take long for all three women to get big bellies either.

     Fortunately, the local obstetrician was very understanding 
and didn't ask any questions when all three showed up pregnant at 
the same time.

     As it turned out, Jackie "caught" first, followed by Tammie.  
Jenny was starting to feel left out when she finally stopped 
having her monthlies as well.

     When the time came for the delivery, Jenny and Jackie each 
had a little girl while Tammie had twins: a boy and a girl.

     "Good," Tammie said, finally satisfied.  "Three more little 
girls for Jimmy to fuck; and a boy to help you girls, when your 
big brother gets too busy getting his daughters pregnant."

     None of the women wanted to give up Jimmy; and he was 
willing to keep fucking all three of them.  So, over the next 
several years, Jimmy's sisters and mother had several more 
sister/daughters and brother/sons for Jimmy.  Until one day, 
almost thirteen years after that first night with his sisters, 
Jimmy's eldest daughter turned twelve years old....

     But that's another story.
