"So my sister lost a drunk bet to my buddy and had to let him fuck her. Whatever, twenty year olds make bad decisions, who am I to interfere. What she doesn't know is I lost a bet to him earlier that week. My penalty? Poke holes in every single condom in her nightstand. Every. Single. One. Pin straight through the tip, real tidy, you can't even see it.
So now here we are in her living room, my friend is balls deep in her tight little tanned ass, pounding her face into the throw pillow my mom made, and she's moaning like a cat in heat thinking she's safe because "he's wearing protection." Look at her, hair everywhere, lipstick smeared, tits swinging, that perfect little arched back, ass up like she was built for it. She has no idea that the rubber on his cock is basically a sieve. He knows. I know. She doesn't. That's the joke.
He's been planning this for two years, ever since she turned eighteen and started filling out. He's gonna nut so deep in her tonight her ovaries will hear it. And in nine months when she's waddling around with a swollen belly crying about how the condom must've broken, me and him are gonna be on the back porch sipping beer like absolute fucking villains. I'm gonna be the world's best uncle to my own nephew, who is technically my buddy's son, who my sister will swear up and down was conceived "by accident." Greatest bet I ever lost."
