Well, actually...

You sigh... “Well, don’t get me wrong. I’d love to seduce your sister. It’s just that, I kinda thought watching you seduce her would be the fun part.”

Carrie leans in toward you. “How well versed do you think I am at the art of sister seduction?”

“I could imagine you doing well if called upon” you answer with a smirk.

“Paint me a picture.” She replies, returning your smirk, squeezing her cleavage together with the tops of her arms.

“Yeah?”

“Yeah. Tell me what you want to happen and maybe we can make it happen. Convince me. I’m horny tonight.” Carrie licks her lips.

“You’re horny every night.”

“I don’t see how that’s relevant.”

She has a point. So you ponder for a minute and, as she says, start to paint a picture. “Well you invite her over. But when she walks through the door and sees you she realizes that something is... different. You’re different. I mean, you’re you, but you’ve embraced your innermost perversions and are no longer to show the world that you’re a...” you search your mind for the right words.

“Slut?” She smiles and wiggles for you.

“Yeah. Maybe more like a...”

“Living fuck toy, corrupted by her own desires and her man’s gorgeous cock?”

“Yeah,” You say. “Something like that.”

Carrie licks her lips again. She takes a deep breath. Her lovely chest heaves up and down.

“Gently and matter-of-factly you start to tell her the rules of the household. Things like, ‘no closed doors’ and ‘no underwear ever.’”

“Or ‘only underwear and no clothes. But never both.’” Carrie seems to be into it. She likes where this is going. “And you have to rub one out every day.” She smiles and you’re not sure if she’s smiling because she isn’t thinking of this as her actual future reality or because she is.

And from there all it takes is for you to tell her how much better life is having given in to it all.

The room is quiet for a bit. Then your girlfriend smirks “fuck it. Let’s just do it” as she starts to rub your exhausted but bulging crotch.

“You mean... have sex or... this plan?” It’s crazy that she’s ready to go again.

“Why not both?” She asks. “It’s early. The only question I have is... what’s your favorite flavor of fuck toy?”

You cock your head not sure what she’s asking.

So she clarifies “Bimbo? Bad girl? Sex ****? What do you want my sister to see when she walks through that door?”

You don’t have an answer so you promise to give it some though my as Carrie climbs atop your sweaty body and fucks you. And then as you sleep and awake to a passionate morning fuck, then off to work, still pondering her question. Few men have their girlfriend ask how they want her to transform herself.

When you make your way to her place that evening, she greets you with a lanky little cami, and something new. A big bandage on her chest above her left breast.

“Want to see it?” She asks proudly, pulling it off to expose a fresh tattoo that says “USE ME”

You’re shocked. “Wow.” You say. “That’s... permanent.”

“So is seducing your sister. Can’t ever take that back.” She winks. “I figure this would work whatever look I try to pull off. So... do you finally have an answer?”

And as Carrie’s question rings in your ears you know you do.
