Unspoken Pleasure (erotica)
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."

I could see now that she was teasing me. Using dirty talk to get me to go first. Only she didn't need to tease -- I was ready to burst already. But I held on. I knew I had to. If we stopped now Emily would just make me go all over again. I had to let her have her fantasy, just like she said: get as close to the edge without going over.

I shifted a little and Emily warned me that I 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 I reached up and grabbed her breasts. Pinched her nipples. I felt her pussy clench as I did it.

"God, I love these," I said.

"I always thought they were too small."

"They're perfect. You're perfect."

Emily reached back and cradled my balls. Two could play this game apparently. "These are really full," she said, "I don't know if I've ever felt them when they're like this."

"Be careful," I 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." I groaned.

"You might give me quintuplets, all that sperm. Fuck. You'd better not cum in me, Ryan."

"I won't," I 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," I said. Emily just winked. I decided to try giving her a little scare. I flexed my penis in her pussy, almost like I 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 had me there, big guy."

"Worth a shot," I 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. I groaned. I was getting close now. My need to explode slowly shifting from urge to reality.

"I'm like, really fertile now, too," Emily said, "Like, I could probably get pregnant just from standing near some sperm today. My little egg is in my womb just waaaaaaaaiiiiting for some big bad Ryan spermies to come inside."

I rolled my head back. All this talk was driving me crazy. I 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.

I 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..." I said.

"OOOO, yeah. I can feel that," Emily said, "Your cock is like... swelling up inside me. Fuck. And I 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 replace 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 give me his baby," she started to chant, "My little brother's going to give me his baby."

"No," I 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." I still had time, I could feel it. Maybe if we were actually humping I would go, but just sitting here, I 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. I got so used to having you in me. Maybe I forgot how much I need that cock in my pussy."

"I missed you, too," I said.

"I know we didn't... Maybe I didn't say it enough. But you know that I love you, Ryan. I mean it. Please. Please tell me you still love me."

"Oh God, Emily. Of course I love you. I 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 came out of nowhere. That little spark went straight to a raging conflagration, skipping every step in between. I raced to shove her back, to get my cock out of her pussy before...

"I win!" Emily threw her arms up in triumph.

I came inside 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 replace 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.

I wrapped my arms around my sister, thinking I could pull her off my cock, but she held me so tight. Her body convulsing. And then a noise came out 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.

"hhhhhhrrrrrrrrRRRRRRAAAA 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. I held onto my shaking sister as we both came and came like we would never stop. "I LOVE my brother's cock!" Emily howled, "I LOVE my brother's CUM!"

Impossibly I 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. I 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 same as a sob. I 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 I told her I loved her too.

My parents heard us. Of course they did. My ears still echo from Emily's orgasmic cries. Later, after she and I were able to joke about it, I named it her 'pregnancy shriek.' Her announcement to the world that she had conceived. I joked that she could join the X-Men, but of course that would require someone to knock her up every time they 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. I 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. I know we did. And it was the best decision we ever made.
