Make her beg for me

"Please Christy," she said again.

A wicked grin spread across my face. "Please what, Alice?" I bat my eyelashes at her playfully.

"Oh fuck, I'd knew you do this. You always do this in my dreams. Make me beg over and over."

I kissed the inside of her thighs as confirmation. "I don't know what you're talking about."

"Oh Christy, please eat me out." She started squirming. "I need your tongue on my clit, your fingers inside me, toying with me." She tried to squeeze her things together but I kept them apart. "Just like that, Christy, you always know just how to treat me."

"Like a slut?" I offered.

"Like a fucking hole, like just a tongue, like whatever you want me. Fuck, when did I become such a sub?"

I slapped her ass, causing her to lurch and gasp. "You've always been a slutty sub," I told her. "You're just now realizing it. And you're the biggest sub of all for your big sister, right?"

She nodded. "Your sub, your slut, your everything. I'm yours, I'm yours, I'm yours! Now take what's yours, please! Take me, and fuck me, and lick me, please Christy! I've waited so long, I've been a good girl!"
