Unspoken Pleasure (erotica)
Too Far: 6

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.
