Tell her about the time you fucked her boyfriend

"More than two dots" You say, puffing yourself out, partially to display your anger, partially to display your breasts. "And remember that cute boy you dated when we were younger, Phillip?" Meg smirks. "One of them would be him."

Meg smiles. She doesn't seem as shocked as expected she'd be. Maybe she just doesn't care. It's been years since Phillips and it turned out he was a pretty big cad.

Still, you're going to let her know what happened. You're going to prove that you're not the prude she's saying you are.

"Remember that night that Mom and Dad were out of town and you were excited because you could have him sleep over?" You say. Meg nods. "Good. Well, in the middle of the night he came into my room. He started telling me how pretty I was, and how much he thought of me. And I told him I wanted to feel his cock. But that could never be enough. Pretty soon he was in my bed and we were fucking." You let that sit out there for a bit, looking at your slutty kid sister, with pride. Feeling like you've finally proved to her that you're a bad girl too.

Meg just starts to laugh. Fuck her.

"You think I didn't know about that?" She says. "Phil went into your room to fuck you because I asked him to." She beams a big smile.

You try not to look shocked. But you can't help it. Meg has the upper hand again.

"I figured you could use the self esteem boost. I asked him if he'd go fuck you. Then when he came back I was so turned on, I sucked his cock clean."

That's it. There's just no competing with Meg's perversion. Your furious. Your so fucking turned on.

You go to slap her. And you just make the slightest contact with your cheek, when Meg grabs your hand. She's quick. She grabs your hand and pulls you toward her, wrapping your hand around the back of her neck sensually.

She bites her lip. And she speaks softly, passionately. "And do you want to know the truth? That was the best blow job I ever gave." She glances downward, downward toward your crotch, just briefly. "It wasn't just because his cock had pussy juice on it. I've eaten pussy since then. I've sucked cocks that were covered, drenched in pussy juices since then. It's never been the same." She pulls you closer to her. You tremble. "It's because it was yours." Meg says.

Is she trying to seduce you? Is she trying to prove she's sluttier than you by seducing her own sister? Isn't that what you were considering doing? Were you? You can't think straight. But you feel yourself falling into Meg's spell.

"What... what are you saying?" You ask.

"I'm saying, I want to know that taste again. I want to know that exact taste. I'm asking if you'll...."
