Trying to Breed My Little Sister (bg/mg, inc, ped, unsafe)

Summary:  A teenage boy begins having some fun with his younger 
sister…then tries to knock her up… 



It all started years ago, during the summer back when I was eleven 
and Michelle (my sister) was nine.  

By that point our parents had decided that we were old enough to be at 
home alone while they were at work.  For the first four weeks of that 
summer, pretty much every day when we were home alone, Michelle would 
say she was bored.  For whatever reason, the first time she told me 
she was bored, I jokingly suggested that we could play a game of “I’ll 
show you mine, you show me yours.”  She called me an “idiot” and walked 
off.  I thought the suggestion of playing “I’ll show you mine, you show 
me yours” was funny, so every time after that, whenever she said she 
was bored I would suggest that we could play a game of “I’ll show you 
mine, you show me yours.”  She generally called me an “idiot”, or 
something else along those lines.  

Then, one Friday, she actually said, “okay” and told me to go first.  I 
dropped my pants and underpants, she stared at my crotch for a few 
minutes, before I pulled my pants and underpants back up.  Then she 
pulled her shorts and panties down, I stared at the hairless slit 
between her legs for a couple minutes until she pulled her shorts and 
panties back up.  That first game of “I’ll show you mine, you show me 
yours” was fun, but it didn’t last much more than five minutes.

During the week that followed (every day when we were home alone 
anyway), Michelle and I would drop our pants and stare at each other’s 
hairless crotches.  Each day the game of “I’ll show you mine, you show 
me yours” lasted a little longer: ten minutes…fourteen minutes…nineteen 
minutes…twenty-three minutes, and the last day of that week a full 
half hour.

The following Monday I suggested we could try playing a game of “you 
touch mine; I’ll touch yours.”  Michelle said “no” but offered to play 
another game of “I’ll show you mine, you show me yours;” I was okay 
with that idea.  That game lasted a full forty minutes.  Same thing 
happened on Tuesday, except our game of “I’ll show you mine, you show 
me yours” ended up lasting for almost an hour.  By the time Friday of 
that week hit we were still playing “I’ll show you mine, you show me 
yours,” Michelle suggested that we take our pants off completely, and 
we spent over three hours staring at each other’s crotches.

By the end of that summer we were spending almost the entire time our 
parents were at work naked from the waist down, and staring at each 
other’s hairless crotches.

***

The following summer, Michelle actually warmed up to the idea of “you 
touch mine; I’ll touch yours.”  It was really awkward for the first 
few days: we kinda just poked at each other’s crotches with the tips 
of our fingers and giggled.  

After a couple weeks of playing “you touch mine; I’ll touch yours” we 
began to understand each other’s anatomy.  Soon touching became 
feeling, which became rubbing and stroking…  

One day, around the middle of the summer, Michelle had my balls cradled 
in the fingers of her left hand as she was moving her right hand 
up-and-down the length of my twelve-year-old dick.  Then something 
happened…something I didn’t understand at the time: my butt-cheeks 
tightened.  For a second, or so, I wondered what that was all about.  
My train of thought was interrupted by the feeling that my balls had 
tensed up…  An instant later it felt like something was rocketing up 
the little tube on the underside of my dick…  Before I could really 
comprehend what was happening, a spurt of thick creamy-white liquid 
shot out of the little hole at the tip of my dick; it arced up in the 
air, before falling back down and splattering across the front of 
Michelle’s ten year-old thighs.  

My little sister and I were both dumbfounded, and could only watch as 
another five spurts of the thick creamy-white liquid followed the same 
trajectory as the first…

“Euuwe! It’s all over my legs,” Michelle complained after the last 
spurt hit her legs and my dick began to wilt.  

I offered to clean the thick creamy-white liquid off my sister’s legs.  
She was more than happy to let me clean up the mess of goo that was 
splattered over her legs.  I was a bit surprised by how warm the goo 
felt when the tip of my finger first touched that first glob.  Even 
more surprising, though, was the fact that I had this strange urge to 
move the goo up to my sister’s slit and to rub it in…what the hell was 
that about?

Pretty much every day that we played “you touch mine; I’ll touch yours” 
for the rest of the summer the same thing happened.  Well, more or 
less: as time progressed Michelle seemed less and less bothered / 
disgusted by the goo that shot out of my dick landing on her legs.  

***

At the beginning of the following summer, when I was thirteen and 
Michelle was eleven we picked up playing “you touch mine, I’ll touch 
yours” where we had left off at the end of the previous summer.  There 
was something slightly different than the previous summer, though: 
Michelle didn’t want me to clean up the white goo that shot out of my 
dick and splattered on her legs, she wanted to do it herself.  

Over the course of the first month of that summer, we continued playing 
“you touch mine, I’ll touch yours” and Michelle continued to clean up 
the goo that landed on her legs.  The thing is, the way she was 
cleaning it up; she began spreading the white goo around on her thighs…  
After a couple weeks of her cleaning it up, she was rubbing it into her 
skin: almost like it was a lotion…  

Then one day, must have been about five weeks into the summer vacation 
from school, I suggested we try a different version of “you touch mine, 
I’ll touch yours:” sitting down, with her on my lap facing me.  I was 
actually somewhat surprised that Michelle said ‘okay’ the first time I 
suggested it; although, I suspect she was agreeable to the idea since 
it meant we wouldn’t be spending so much time standing.  That first 
time we sat while playing “you touch mine, I’ll touch yours” it must 
have taken us a good ten minutes to figure out exactly how we had to 
sit to be able to face each other, and be able to properly touch each 
other’s crotches at the same time.  Through a bit of trial-and-error, 
we discovered that the best position was for me to be sitting with my 
legs spread slightly, and Michelle sitting on the middle of my thighs 
with her knees on either side of my hips.  

Of course with us in that position, when the creamy-white goo shot out 
of the little hole at the tip of my dick, it couldn’t land on her 
thighs: it landed on her belly, just below her bellybutton.  When 
Michelle started rubbing it into her skin, like it was some sort of 
hand cream or suntan lotion, I got this urge to move her hand down 
towards the slit between her legs.  Before I realized I had moved an 
inch, I watched as my hand took hold of my little sister’s wrist and 
began moving her hand downwards on her belly.  When she asked me what 
I was doing, I told her “I thought it would be neat if the goo was on” 
her slit.  I wasn’t sure why I thought it would be neat, but I did.  
She gave me a funny look and told me that once the goo was on her body 
it was her decision what to do with it, and she went back to rubbing 
it into the skin on her belly.  

We continued playing “you touch mine, I’ll touch yours” sitting down 
like that for the rest of the summer.  I never tried to touch 
Michelle’s hand or move the white goo to a different part of her body; 
she did, however, begin to move the goo farther and farther down on her 
belly.  

Then, the last week of summer vacation, Michelle shocked me by actually 
moving the white goo onto her slit.  She didn’t really seem to rub it 
into her slit though…

***

At the beginning of the following summer, when I was fourteen and 
Michelle was twelve we picked up playing “you touch mine, I’ll touch 
yours” pretty much where we had left off at the end of the previous 
summer.  Michelle sitting on my lap and, her moving the white goo down 
from her belly onto her slit.

About two weeks into the summer vacation, while Michelle was sitting 
on my thighs and she was stroking my dick, I pondered an ideal out 
loud, “maybe I could shoot the white goo onto your slit so you don’t 
have to move it there…”

The instant after I finished saying those words I would have sworn 
that Michelle was going to say “no way”; but she didn’t.  She just 
kinda froze in place: her hand stopped moving on my dick and her 
breathing became extremely regular.  

After a minute of very awkward silence she asked if I could “tell when 
the white goo’s about to shoot out.”  After I told her that I could, 
she suggested we try getting her slit to the tip of my dick.  After a 
couple tries, we discovered that if she kind of half-stood and shoved 
her hips forward her slit would be just above the tip of my dick.  

Secure in the knowledge of how to get her slit to my dick, Michelle 
went back to stroking my dick.  

We sat silently for a few minutes while Michelle moved her 
twelve-year-old hand up-and-down the length of my fourteen-year-old 
dick.  

“Gonna shoot,” I half groaned as my butt-cheeks tightened.  In a flash, 
Michelle let go of my dick.  As she half-stood I noticed that my balls 
had tensed up.  She shoved her hips forward: just as the tip of my dick 
brushed against her slit I felt the white goo rocketing up the little 
tube on the underside of my dick.

A small fraction of a second later the first spurt of thick 
creamy-white liquid shot out of the little hole at the tip of my dick 
and splattered directly onto Michelle’s twelve-year-old slit.  

My little sister held steady, as spurt after spurt of the creamy-white 
liquid erupted out of my cock and splattered across her slit.  

After the creamy-white liquid stopped shooting out of my dick, Michelle 
informed me that “having the white goo shoot directly onto her slit 
felt neat” and that she “wanted to do that again”.

So for the following three weeks, every time we played “you touch mine, 
I’ll touch yours” we did it exactly like that: Michelle sat on my 
thighs, then when I was about to shoot the white goo I’d give her a 
second or two of warning and so she could half-stand and shove her hips 
forward; putting her slit was against the tip of my dick just as the 
white goo shot out.  

***

Then, one day, just after Michelle sat on my thighs, she surprised me 
by saying she wanted “to try something a little different”.  

Despite having no idea what she wanted to do differently, I said 
“sure”.  

Barely a millisecond later, she had half-stood and moved her hips 
forward to the point where the tip of my dick was brushing against her 
slit: this was no different than what she did so I could shoot the 
white goo on her slit… Then she did something which really was 
different, she continued moving her hips forward: putting the tip of 
my dick just below her slit.  Before I could wonder what she was up to, 
she was lowering her body down and, in doing so, forcing first the tip 
of, then the entire head of my dick into her slit.  

At that point, with the entire helmet shaped head of my dick submerged 
within her slit Michelle stopped moving.  In a serious sounding voice 
she told me, “Clair said this is lots better than playing ‘you touch 
mine, I’ll touch yours’”.  

“It’s better so far,” I quickly agreed, before silently wondering who 
Clair was.

Michelle nodded then continued slowly moving her body down.  In one 
single motion it went from being just the head of my dick in her slit 
to the entire length of my dick being submerged within the warm moist 
recesses of her twelve-year-old slit: and DAMN did it feel GOOD…far 
better than anything we’d done previously.

It was only after I felt her butt cheeks press against my balls that 
Michelle spoke again, “Clair says to make sure to pull your dick out 
of my slit before you shoot the white goo…”

“I’m sorry, who’s Clair?” I interrupted, not being able to think of 
anyone with that first name.

“My friend Marie, her cousin,” Michelle answered before reverting back 
to her previous comment, “Clair says you can shoot the goo on the 
outside of my slit, but that bad stuff will happen if you shoot it 
inside.”

I wasn’t quite sure what she was talking about, but I found myself 
saying, “Okay…”

“So,” Michelle continued, “You gotta tell me when you start shooting 
so we can get it out.”

Nodding I replied, “Yeah, right.”  

As my lips met after speaking those two words, Michelle began to slowly 
lift her body up: my dick slowly sliding out of her slit.  

Then, when just the head of my dick was still inside her slit, she 
reversed course and began moving her body back down: my dick sliding 
back in.  

As my sister repeated those up-and-down movements with my dick sliding 
in-and-out of her warm moist slit, I began thinking about the 
information she had relayed from Clair…clearly the ‘bad things’ was 
pregnancy, but Michelle was only twelve, so we really wouldn’t have to 
worry about that.  

My mind kept wandering to the statement Michelle had made about 
‘telling her when I start shooting’: something about it didn’t quite 
make sense.  After a few minutes it hit me: if I told her WHEN I START 
shooting, then there was no way that the first spurt wouldn’t end up 
going inside her slit.  Wondering if I had heard her wrong, I asked, 
“I gotta make sure to tell you when I start shooting, right?”

The moment I spoke those words Michelle instantly froze in the middle 
of her down-stroke: about a third of the length of my dick inside her 
slit.  A fraction of a second later she practically leapt off my lap: 
the third of my dick which had been in her slit quickly flopping out 
and slapping against my lower belly.  

For a few seconds she stared at my dick before commenting, “You’re not 
shooting…” in a confused tone.

“That’s right, I’m not shooting,” I confirmed her statement before 
explaining and reiterating my previous statement, “I wanted to make 
sure I understood: I’m supposed to tell you when I start shooting, 
right?”

“Oh…yeah: tell me when you start shooting so I can do like I just did,” 
she answered as she lowered her body back down.

As the head of my dick re-entered my sister’s slit I suggested, “I 
don’t think you gotta jump off so quick.”

“Gotta get off quick ‘cause if you shoot it inside my slit bad stuff 
will happen,” she restated what she’d already told me she’d heard from 
Clair while moving her body up-and-down: my dick sliding in-and-out of 
her slit.

“Yeah: I know, but if you jump off that quick none will get anywhere 
near your slit…and you like it when it shoots onto your slit…” I 
reasoned.

“Oh…  Yeah…right…” she replied in a marginally pensive tone, while 
maintaining her up-and-down movements.

Perhaps thirty seconds after Michelle had accepted my reasoning for 
her to not pull of my dick too fast I felt my butt-cheeks tighten under 
me.  Per what we’d just discussed, I kept quiet.  My balls drew up, 
and I kept my mouth shut.  I felt the white goo rocketing up the little 
tube on the underside of my dick, and still I remained silent.  Then, 
just her butt-cheeks bumped up against my balls, and as the first spurt 
of thick creamy-white liquid began to shoot out of the little hole at 
the tip of my dick I declared, “Shooting.” 

Michelle immediately hopped up: my dick quickly being withdrawn from 
her twelve-year-old slit.  As I had anticipated, the first spurt of 
creamy white goo shot out of my dick while it was still in the process 
of sliding out of her slit.  Less than a second later the second spurt 
splattered directly onto Michelle’s twelve-year-old slit.  It was 
quickly followed by a third, and a fourth, and a fifth, and a sixth: 
those subsequent spurts of white goo coating the outside of her slit 
and making it impossible to tell that there was a spurt leaking out of 
her slit.  

“Wow, that was great,” Michelle commented shortly after the 
creamy-white liquid stopped shooting out of the little hole at the tip 
of my dick.  

“Yeah…it was…” I panted an agreement.  I took a deep breath then 
suggested, “We could do it again, if you put it back in…”

A huge smile appeared on my sister’s face as she lowered her body back 
down: my dick once again sliding into her slit.

That day we went through the same thing two more times.  Both times she 
moved her body up-and-down: my dick sliding in-and-out of her slit 
until I told her that I was “shooting” as the first spurt was spraying 
out of the little hole at the tip of my dick.  

For the following week we did it exactly the same way two or three 
times each day and every day while our parents were at work.  

***

It wasn’t until I had shot seven of eight spurts into her slit that I 
came to the conclusion that I actually WANTED to knock Michelle up.  
There was something I really liked about the ideas of my little 
sister’s belly getting big with my baby growing inside it and being the 
father of my niece or nephew.  So, I decided that I would do my utmost 
to knock up my sister.  

After I had come to that conclusion, I didn’t tell Michelle that I was 
“shooting” until the second spurt was leaving the little hole at the 
tip of my dick.  

For the remainder of the summer I did just that: shooting two spurts of 
cum into my sister’s slit before telling her we had to pull-out.  

At the time I was truly disappointed that, despite all my efforts, my 
sister didn’t get pregnant.  Looking back on it, it is a good thing she 
didn’t get pregnant: if she had I’d have been in SO MUCH trouble…
