Your sister

“It was my sister?” You’re perplexed “it was Emily? What?” This makes no sense.

But Carrie gets it “we met at that orgy. I made her cum... your sister is a prolific cummer you know.”

“What?”

“We stayed in touch and she asked me if I could help her make this little fantasy come true.”

You still can’t wrap your head around this. “It’s... you’ve been... this whole time?” You’re stunned as Carrie confirms your inquiry with a teasing look “but how did you know that’s what I was going to request when you said...”

“Little suggestions here and there. I told your sister to start wearing sexier outfits. Just a little bit. And then last month remember when I pointed out those twins in the bikini. Oh and there’s this.” Carrie walks over to her vinyl collection and grabs the record that’s been sitting in front this whole time. Twisted Sister.

“Is it?” Carrie asks. “You just told me you wanted to fuck your sister.”

You seethe, only half seriously. “You’ve been conspiring with her this whole time.” And suddenly something occurs to you. “Have you been fucking her the whole time?”

Carrie shrugs. “Well... yes”

“Many times.” Carrie answers.

You start to pace. “I don’t even... I don’t know what to do about this.”

“What are you taking about? What you do about it is fuck your sister. You’ve hit the taboo jackpot. She wants to. You want to. I want to help.”

It’s true. But you can’t help but feel a little played by Emily. Growing up you were always planning each other. Is this her tricking you? In a way that ends with your cock inside her. Should you care. Should you just fuck?

“No.” You say to Carrie much to her dismay. “I mean, yes we’re going to have some fun but first we’re going to have some fun.” You’re not exactly making sense and you can see it on her face. “Don’t tell Emily that I explicitly agreed to anything. Tell her you’re positive I’m willing to do it. But I’m really really getting into...”
