Truth

"Well?" your sister moaned and her knees trembled for a minute. You had trouble finding your tongue because you couldn't help but think of it swirling around Rachel's pink nipples. They had to be diamond-hard, and he could only imagine that her clit was at least as hard as she played with it under the froth of creampie.

"I invented a...a...spray," you stammer. "It's um...fuck, Rach..."

"Mmm...later, Mike. You will fuck me again, spray or not," she moaned. "I've wanted you forever, but we're sister and...mmmm....fuck....brother," she said. The tidal wave of cum seems to have slowed down from her pussy, but she's still playing in the sloppy mess. She leans back against the wall for support as her legs start to shake again. "Always wanted you," she purrs out, staring at you like a predator through her sweat-matted hair plastered on her brow.

"Jesus, Rach," you say, you hand on your flacid, cum-soaked cock. Life is returning to the rod, and quickly. "The spray makes women want me."

"Want to fuck you, you mean?" Rachel says and a fresh push of her own juices start flowing. "Because, Mike, I want to fuck you again. I want to fuck my brother."

You bite your lip and feel your cock surge in your hand.

"Mom will be home soon," you say, common sense piercing through the veil of lust in your mind. A panic sets in.

"We're talking here, fuck her!" your sister says, almost spitting out the words like venom. And then a light bulb goes off; her whole expression lightens and she cums again. "Fuck her, Mike. I want to watch you fuck our mom," and the words make her thighs and abs pulsate and your cock is iron.

"Okay, sis," you say, your brain on a sex-addled high. "We need to shower. Right fucking now," you manage to say, that common sense creeping in. "And we need to mop up the cum."
