Going Too Far: >5
Emily rocked back onto her knees. She looked down at our juncture and smiled. "I always thought that looked so
hot. You buried inside me."
| could see now that she was teasing me. Using dirty talk to getto go first. Only she didn't need to tease -- |
was ready to burst already. But | held on. | knew | had to. If we stopped now Emily would just makego all
over again. | had to let her have her fantasy, just like she said: get as close to the edge without going over.
| shifted a little and Emily warnedthat | wasn't allowed to thrust. Only to lie back. As if that somehow made
things safer. Like her warm, tight pussy wasn't squeezing, pulsing, pulling at my cock for its precious seed.
Instead | reached up and grabbed her breasts. Pinched her nipples. | felt her pussy clench as | did it.
"God, | love these," | said.
"| always thought they were too small."
"They're perfect. You're perfect."
Emily reached back and cradled my balls. Two could play this gapparently. "These are really full," she said,
"I don't know if I've ever felt them when they're like this."
"Be careful," | said, "They're really tender."
"Is all that build up just from me?" Emily asked, "I mean, you were unloading at least five times a day and then...
Nothing. There has to be, like... God, at least 25, 30 regular cums in there." | groaned.
"You might givequintuplets, all that sperm. Fuck. You'd better not cum in me, Ryan."
"I won't," | said.
"I mean, just imagine, you think you've got it under control, then suddenly you slip and WHOOPS! There's my
baby brother's baby inside of me."

"You're cruel," | said. Emily just winked. | decided to try giving her a little scare. | flexed my penis in her pussy,
almost like | might be cumming. She gasped, her face went white, and she even started to lift off a little. But
then she laughed. "Ohhhh, you almost hadthere, big guy."
"Worth a shot," | said.
"You'll be the first to give," Emily said, "I just know you will. And then you'll know that I'm the big sister."
She bared down on my cock with her cunt, then laughed again. | groaned. | was getting close now. My need to
explode slowly shifting from urge to reality.
"I'm like, really fertile now, too," Emily said, "Like, | could probably get pregnant just from standing near some
sperm today. My little egg is in my womb just waaaaaaaaiiiiting for sbig bad Ryan spermies to cinside."
| rolled my head back. All this talk was drivingcrazy. | didn't want to make my sister pregnant but my body
did -- my instinctive drive to reproduce didn't care about college or disappointing my parents or any of that. It
just wanted to make more mes and my big sister was telling it exactly what it wanted to hear.
| started to pant from all the pressure. The little spark of orgasm that started in the base of my penis slowly
spread upwards.
"Getting... close..." | said.
"0000, yeah. | can feel that," Emily said, "Your cock is like... swelling up inside me. Fuck. And | haven't even
touched my naughty little clitty. I'm telling you, Ry, I'm never going back to condoms. We're going to have to find
another way. This... this is just too good."
She shifted her weight again, moved up more on her feet. Ready to spring off at the last second. She could see
the cliff coming now and my crazy sister just slammed on the accelerator.
"My little brother's going to givehis baby," she started to chant, "My little brother's going to givehis
baby."
"No," | said, teeth grinding, "Can't... Won't..."
"Ready to give up then, little Ryan? Admit that your big sister is the best?"
Damn her. "N... no. Not yet." | still had time, I could feel it. Maybe if we were actually humping | would go, but
just sitting here, | could maintain control.
Emily relaxed a little. She looked down at where we were joined again. She seemed to be thinking. Then she bit
her lip and her eyes went wide and wet.
"I missed this," she said, "I really did. | got so used to having you in me. Maybe | forgot how much | need that
cock in my pussy."
"I missed you, too," I said.
"I know we didn't... Maybe | didn't say it enough. But you know that | love you, Ryan. | mean it. Please. Please tell
"Oh God, Emily. Of course I love you. | love you more than anything in the world."
And then Emily's pussy squeezed my cock as hard and tight as I'd ever felt it. Not just a grip but a rolling wave
that went from my root, up my shaft, then squeezed my head. Her eyes popped open and so did mine.
It cout of nowhere. That little spark went straight to a raging conflagration, skipping every step in between.
| raced to shove her back, to get my cock out of her pussy before...
"I win!" Emily threw her arms up in triumph.
| cinside my sister. Not a little spurt but a massive blast of joyous sperm that shot straight into her. A fire
hydrant of fertility just opened up -- not a stream or a spurt -- but an explosion of force that filled her pussy in
one shot.
"OH F...!" Emily started to lift off, but then my cum hit her cervix and she stopped. Her eyes rolled back in her
head and she fell forward. My cock still buried inside her. My second blast was more voluminous than the first.
My dick kept going back to the well, expecting to find it empty, but instead there was still more than it could
carry and it raced to dump the contents in Emily's snatch before rushing back for more.
| wrapped my arms around my sister, thinking | could pull her off my cock, but she heldso tight. Her body
convulsing. And then a noise cout of my sister that I'd never heard before and would never forget.

It was a deep, primal sound. Something ancient from her animal brain. It started almost like a whisper and then
immediately ratcheted into a deafening shout.
"hhhhhhrrrrrrrrfRRRRRRAAAA AAAAAAAHHHHHHHHHHHH! FUCK! Oh FFFFFFFFFUCK! You're cumming inside
MEEEEEEEEEeeeeeeeeee!"
Another blast. Another. Filling my sister's fertile twat over and over again. Ripping right into her womb. Our
orgasms simply swallowed us up. | held onto my shaking sister as we both cand clike we would never
stop. "I LOVE my brother's cock!" Emily howled, "I LOVE my brother's CUM!"
Impossibly | felt my balls finally start to empty. My cock was still firing, but now it felt like smaller bits. Less and
less. Emily's orgasms subsided with mine. Oh God. There was no way that. | mean. She was more than
pregnant... Oh God. She stood up, both of us sticky with sweat. As Emily got to her feet, a rivulet of her brother's
sperm streamed out of her pussy and splashed onto my leg. She reached her hand down to cup under her sex.
And then she started to laugh. A kind of low, thing, that sounded almost the sas a sob. | leapt up and
wrapped myself around my big sister.
"I love my brother," she said. Whispered it into my ear. "I love my little brother so much."
And | told her | loved her too.

My parents heard us. Of course they did. My ears still echo from Emily's orgasmic cries. Later, after she and |
were able to joke about it, | named it her 'pregnancy shriek.' Her announcement to the world that she had
conceived. | joked that she could join the X-Men, but of course that would require someone to knock her up every
tthey fought a bad guy.
When they heard Emily, Mom and Dad raced downstairs. We were still stumbling around like zombies. Covered in
sperm and girl cum. There was no point in lying about it. This is meant to be a happy story in the end. So I'll just
say that things got ugly.
The good news is that this finally got us out of the house. Pretty much forever, actually. We got our own place. |
turned down the scholarship and followed Emily to school. Got a job to help pay for things while she worked on
her degree. We stopped fucking after that fateful day. Instead we started making love. I've been lucky enough to
hear Emily's amazing pregnancy shriek three times so far. I've don't think I'll ever get tired of hearing it. You
really can go too far. | know we did. And it was the best decision we ever made.
