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. The knowledge that neither child knew the full

consequences of what they were doing, was almost mind-blowing. I

had fantasies of Judy being six months gone; her now-flat cute

little belly sticking out and heavily swollen with her own

brother's baby inside her; neither child having the faintest idea

of what had happened, or what was going on in her body ... the

two kids still fucking merrily away, without either one knowing

the end results of what they were doing or had done. I almost

had a climax at the very thought.

Bobby and Judy however, weren't really listening to me. The

two kids were too involved in THEIR respective climaxes to pay

attention to their mother having a vicarious one next to them.

"Do it," Judy echoed my words. "Do it, Bobby. I want to

FEEL it squirt inside me." Her sweet young face twisted up into

a grimace that almost looked like pain, as her hips began working

almost frantically to extract her brother's sperm. Judy's mind

might not know the full consequences of her actions with her

brother; but her body was certainly doing everything a little

girl can do to get it to reproduce.

So was Bobby. With a groan he suddenly sank down on his

little sister; frantically rutting into the child while his prick

bulged and spat wad after thick white wad of sperm into Judy's

milking vagina. Bulge after thick bulge rippled through my son's

prick, as the boy bred his little sister like a bull breeding a

cow. Thinking about how the child's tight little tunnel was

squeezing the boy's penis at the same time as it stretched her

inside and then throbbed and spat gob after thick sticky gob of

gooey white cum inside the little girl's sucking young vagina;

splattering incestuous seed against the child's uterus until

Judy's cervix dipped into the obscene pool of her brother's cum

and sucked it into her developing womb, was enough to make me

shudder with repressed need for something similar inside myself.

But this thick white injection of baby-juice, was reserved for my

daughter's womb, so SHE could feel HER brother's baby squirming

inside her cute little tummy, like I had once, not my needing

womb ... as much as I wanted it for myself. I had had MY fun

years earlier, when I had first Robert, and then two years later,

Judith Ann. I sighed for the lost days of my mis-spent youth.

Well, maybe NOT so mis-spent, thinking about the two wonderful

results mating so joyfully here in front of me.

"Do it," I encouraged the boy thickly; my tongue swollen and

swamped with saliva as I almost drooled on the two of them.

"Squirt your spunk as far up in Judy's tummy as you can. I don't

want you wasting any of it on the bed." I could barely choke out

the words; as a climax of my own at sight of the erotic dance

taking place in front of me took me over the edge. I could

barely stand up to see the two kids work out their own climaxes;

Bobby's seed filling his little sister's belly with thick heavy

gouts of pearly white incestuous cum pumping in lusty jets from

his straining, squirting penis against the smooth pink walls of

my daughter's tightly stretched and squeezing little slit.

For not the first time, I wondered if it could possibly feel

as good to Bobby to have Judy's tight little sleeve wrapped

around his swollen prick, as I knew it felt to the little girl to

have him sliding, swelling, then spurting inside her, from my own

similar experiences when I was their age.

"Unh, Uhn, Unh," he panted. Then, "Yes Mom," as his squirts

subsided into just little drops of goo in Judy's belly. My

imagining the sticky mess he had made inside the little girl, as

his prick first spasmed, then squirted, and finally dripped the

last few sticky white globs of incestuous sperm inside his own

sister's tight little tunnel, almost made me cum again.

"Good," I said. "For the next week or so, I want you to

make sure and spunk your little sister's belly as often as you

can. A horny young boy like you should be able to fuck your

little sister at least three times a day, and probably four or

five. OK?"

Neither child even wondered why.

"OK," said Bobby happily; slowly pulling his white-streaked

member out of his little sister's clutching young slit. Even

soft, my daughter's tight little hole clung to the older boy's

prick; following it out, almost looking like a second skin

turning inside-out around the boy's penis, and stripping nearly

every thick drop of her brother's potent seed inside her tummy

where it belonged. I almost collapsed again in orgasm; thinking

about millions of my son's vigorous sperm wriggling up inside the

child's uterus and on into her womb; as each lusty little tadpole

raced the others, vying desperately their in frantic search for

the little girl's waiting and ripening eggs.

"And don't let me catch you wasting any of it outside your

sister," I added; remembering the other day. Over the years,

ever since they first started fucking, I had made sure both kids

knew and experienced ALL aspects of sex ... even those I didn't

care for personally. The kids had taken to sex like ducks to

water; in the last few years, making their way three times

through the Kama Sutra (which I bought the moment Bobby first

ejaculated sperm inside his sister). "Your sister is going to

need LOTS of spunk up in her tummy in the next few weeks, if

she's going to be a BIG girl like her mother," I added. Exactly

how big and how like a mother, I didn't tell them. I figured

Judy would find out soon enough, when her cute little panties

started getting tight. (Or maybe not even then, with a little

bit of luck!)

Bobby just nodded happily; grinning from ear to ear. If his

mother wanted him to spend all of his spunk inside his cute

little sister's tight little sleeve, then he was quite willing to

put it there. I thought seriously for a moment of getting out

the Kama Sutra again ... and then decided that one of the books

my sister had lent me years ago when I was trying desperately to

get pregnant might be better.

"You too," I prompted Judy. "For the next two weeks, I want

you to let me know if your big brother doesn't fuck you and

squirt his spunk in your tummy at least once in the morning

before school, and once at night before you go to bed, besides

whatever fucks you kids do during the day, OK?"

"Yes, Mom." Judy seemed unconcerned and not even surprised

at my insistence on having Bobby ejaculate his seed in her

vagina, instead of squirting his cum in her mouth and ass like he

often did. "Can we do it again now? Please, Mom?"

I was about to say it was getting late, close to school

time, and that her brother probably wouldn't be able to do it

again so soon, when Bobby put the lie to that last, by sliding

his cum-dripping re-erect penis back inside the little girl and

starting to fuck the 11-year-old all over again! I actually SAW

a thick white drop of cum oozing from the end of the swollen

prick, before it vanished again into the child's peach-like

split, that was soon sucking once again at her brother's thick

penis, in hopes of getting the older boy to squirt her tiny

little womb full of life-giving seed yet one more time. Ah, the

resilience of youth!

I settled back down to watch. The two kids might be a

little late getting to school this morning, but there ARE higher

priorities, you know. If necessary, I would write them a note,

or take them to school myself. I knew it would take a little

longer for the boy to ejaculate his cum inside his sister the

second time; so I made myself comfortable while I looked. I

spent the time waiting; daydreaming about Judy having two or even

three kids by her big brother, and her tummy being swollen by a

fourth one, with neither child ever having the faintest idea of

how it happened, or the normal end-result of having a teenaged

boy keeping his nubile young sister's cute little tummy full of

his incestuous sperm. I wanted MY kids to have as much fun as I

did, (or hopefully even more than I had) back when I was their

age.

My orgasm at that sexy thought ripped through me as I joined

my two children in their second and third (Bobby's second, Judy's

third) orgasm of the morning. My stomach rippled, and my vagina

clutched in an unsteady rhythm at my probing fingers; almost in

sync with my daughter's tight little sleeve clamping and

squeezing desperately in frantic attempts to milk each precious

drop of her brother's sperm from the swelling, throbbing, and

wildly spurting member that was filling her tummy so nicely ...

and like *my* tummy hadn't been filled in way too long, it seems.

Millions of tiny sperm rippled through the thick tube on the

bottom of Bobby's prick, before being spat vigorously into the

welcoming young womb of his little sister, where hopefully at

least one would reach the child's waiting egg before the day was

over.

God I love my kids. Judy was going to really enjoy this,

when she finally figured out what had happened, and what I had

done for the two of them.

I sure had, when my parents did it for me and Dan.
