Not Really
                         An Erotic Story

     "Oh Sis, I'm. . ."
     "Don't cum in me, I could have a baby!"
     I looked down at where most of my son's cock had vanished up 
inside his 12-year-old little sister's tight little slit.  From 
the jerking of the fat rod, I knew the boy wouldn't be able to 
hold out, so I knew that I'd better act fast, before it was too 
late.
     Hurriedly, I reached down and grabbed my son's hips, and 
PUSHED, as hard as I could!  The last half-inch of my son's penis 
slid up inside his little sister.  Diane's eyes widened in shock, 
as her big brother's cock stretched her uterus, and then popped 
inside her fertile young womb, as the 15 year old boy began to 
cum.  It was so exciting to watch my son impregnate his little 
sister.  Spasm after spasm shook the boy's body, as he squirted 
gob after thick sticky gob of his potent seed in his own little 
sister's unprotected young womb.
     "Ungh.  Unnngghhh!" grunted Jason.  "Oh God, I'm cumming in 
you!  Oh Diane!"
     Diane whimpered a little, then suddenly seemed to decide to 
accept it.  The little girl wrapped her arms and legs around her 
older brother, and pushed back.  "Cum.  Cum.  Cum in me," she 
said.  "C'mon big brother, knock your little sister up."
     I watched closely, to be sure my son did it right, and left 
every drop of his incestuous sperm in his little sister's tight 
little belly where it belonged.  He did.  It wasn't until both 
children had finished their orgasms, and his cock could no longer 
remain erect, that he pulled out of the little girl.
     I could see a thick white drop of sperm dripping off the end 
of the boy's penis as he withdrew, and shortly a matching drop 
started to ooze out of his sister's tight little crack. I knew my 
son had done it right, and had left a generous helping of his 
baby-making sperm in his little sister's cute little tummy.  
Hopefully, that same tummy would soon be swelling with her big 
brother's baby kicking inside.  Well, if not, I'd see to it that 
Jason kept trying until it did.  My wife was going to be so proud 
of our kids, when I told her.
     I thought about our other two children, and wondered how 
long it would be, before Billy was old enough to father a child 
on HIS little sister, Suzy.  After thinking about this a bit, I 
brightened with a new thought.  Maybe Billy and Suzy weren't old 
enough to MAKE a baby yet, but that didn't mean they weren't old 
enough to practice.  This thought was so exciting, I just knew I 
had to tell my wife.  Since the whole Idea of mating Jason and 
Diane, so that Karen's baby would have a playmate to grow up 
with, had been hers, I was fairly sure she'd go for it.  I could 
hardly wait, until she got home.
