Watching my son

I watched closely as Bobby’s thick prick vanished slowly
into his little sister. Looking at the thick member slowly
sinking into the nubile young girl’s body, you would never think
the older boy would be able to get all of that meat into the
child, without him longcocking her and making her scream in pain.
Judy however, had been fucking her big brother since she was
three years old, and he was five; enjoying it all the while.
Today was no different for that. For something else it was,
however.
I know it’s wrong to let my son fuck his own sister like
this. Even more, I know just how dangerous it is to allow the
boy to ejaculate his seed in his little sister’s fertile young
belly … but I can’t help it; being mesmerized by the sight of
my handsome boy’s prick first bulging, and then throbbing as he
squirted gob after thick white gob of his potent seed into the
child’s womb. Ever since the first time the boy actually
ejaculated in his little sister about four years ago, I knew this
moment would come … and I could no more stop it now, than I
could back then. Watching the two kids progress from simple
feeling-up to oral sex to actual vaginal intercourse to anal sex
and other things even further out had been a constant thrill over
the years. In the last few years, watching them go even further,
as first Bobby then Judy reached puberty was more than just
exciting, it was thrilling, exciting, electrifying, provocative,
exhilarating, and just plain erotic as Hell. That my two kids
were now grownups, (in the only way that really matters) doing
real grownup things, was as stimulating as anything you could
imagine.
Bobby’s panting grew harsher, as his orgasm approached;
while Judy locked her slim ankles around her lover’s legs. There
was no way that steaming load of thick white pregnancy-juice was
going any place except into the little girl’s sucking young womb
where it belonged.
“Do it,” I murmured. “Do it.”
Bobby grinned up and me and smiled; holding his prick buried
to the hilt in his little sister’s belly, while he held off his
approaching climax. They both knew full well how much I liked to
watch them fuck.
“Do what, Mom?” He prompted.
“Yeah, Mom, what?” added Judy. Her grin matched that of the
older boy, as her hips slowly rocked back and forth in an
instinctive copulating motion; her slippery little slit slowly
massaging the thick penis that was buried to the hilt in her wet,
engorged, and wantonly swollen sex.
“Cum in her,” I said. “Shoot your spunk in your little
sister’s womb. You want to cum as far up in your sister’s tummy
as you can.” I shivered at the obscenity of what I was saying.
I know it’s wrong to let my son ejaculate his sperm in his little
sister … especially considering that the younger girl has been
having periods for over four months now; and had finally finished
her first regular flow a little over a week earlier.



Somehow the danger of having my barely teenaged boy actually
impregnate his eleven year old little sister with his incestuous
sperm just increased the thrill of watching the two kids mating
like this.
