Jacking off in your little sister
                         An Erotic Story

     "Mike, did you remember to jack off in your little sister 
this morning?"
     "Yes Mom."
     "BOTH of them?"
     "Aw Geeze.  Mom, I just blew my nuts in Cindy.  Do I have to 
do Jenny too?"
     "Mike, you know better than that.  Jenny's period is in 
about two weeks, and your father and I don't want her missing her 
chance.  Besides, it's time she helped out by having some of the 
babies around here, instead of having me and your Aunt Marie do 
all the chores ... and that means that we expect you to do your 
part too.  So get back in that room, and don't come out until 
your little sister's womb is full of cum, OK?"
     "Yes Mom."
     And don't try to sound like it's such a big chore ... I know 
you like feeling your little sister's tight little slit sucking 
the sperm out of your prick up into her tummy just as much as she 
does ... if not more."
     "Aw Geeze, Mom ... but Jenny's only 10 years old."
     "Ten years old, or 25, your little sister has been having 
periods now for almost a year now ... she's definitely old enough 
to breed.  Or do you want me to have your father do it?  I 
thought you LIKED fucking the little kid ... you've been doing it 
since she was five."
     "Never mind, Mom.  I'll do it.  I just don't like the 
thought of hurting her by getting her pregnant when she's so 
little."
     "You should have thought of THAT, the first time you 
squirted baby-making sperm in your little sister's tummy back 
when she was five.  Now get busy."
     "Yes Mom."
     "Good.  I'll expect you to have both of your sisters 
pregnant before Christmas.  Either that, or I'll have your father 
help out.  Do you want that?"
     "No Mom ... I'll do it."
     "See to it ... and Jenny?"
     "Yes Mom?"
     "Make sure your big brother does it right when he jacks off 
in you.  And when he's finished, I want you to lay there for at 
least half an hour before getting up to let your big brother's 
sperm soak in properly, OK?"
     "But Mom, I'm hungry!"
     "You do what I said.  I'll keep your food hot until you get 
out ... but if you rush the job, you won't get ANY breakfast, you 
hear?"
     "Yes Mom."
     "Now Mike, you take your sister in the other room and jack 
off in her right this time.  I want you to sperm your little 
sister's womb real good at least once before you leave for school 
for the next week.  If you hurry, you'll have time for breakfast 
too; so hurry up."
     "Yes Mom."
     "Geeze, the things you have to do to get kids to do their 
chores today.   <Sigh.>  I swear it wasn't so difficult to get 
you to jack off in me, when Mom had you knock me up for the first 
time."
     <Snicker> "No., it never was."
     "C'mere Little Brother, let's go peek in on our kids, see 
how they're doing, and maybe get a little baby-making practice in 
ourselves."
     "I thought from now on that you were going to leave the 
baby-making to Mike and his two little sisters."
     "Like hell I am.  I just want their help.  That doesn't mean 
I'm going to stop having kids myself.  Or do you want me to get 
Daddy to do the job again?"
     "No ... I'll do it.  You always WERE the boss when it came 
to sex, weren't you Janet?"
     "And always will be too.  And don't you forget it."
     "Yes Dear."
     "C'mon ... if we hurry, we can watch while our son squirts 
his sperm right up inside Jenny's tight little baby-hole, and 
plants a baby in his own little sister's cute little tummy at the 
same time as you jack-off in me, and plant yet another kid or two 
in mine."
     "OoooooOhhHH!"
     "I knew that would get you."
