“Make your sister happy”

Cassidy knows exactly what you mean. She closes her eyes, takes a deep breath, and turns to her sister. Then she smiles and pulls of her sheer top.

“I like your nipple rings.” She says, leaning in, placing her tongue just below the fold of her left breast, then licking upward in a long motion until she’s able to take her sister’s nipple ring between her teeth with a chuckle.

“Please...” Carrie says, eyes closed, body quaking.

Cassidy’s body trembles too, though not in anticipation like her sister, in anxiety, in full understanding of what she’s actually doing. But it doesn’t stop her from wrapping her tongue around her sister’s nipple and then sliding it off and up to her neck.

“Can I put my tongue in your mouth?” Cassidy asks.

“Please..” Carrie responds.

And then like a good **** Cassidy turns to you, waiting for your approval. She understands already.

“Do what pleases your sister” you say, your cock throbbing.

So Cassidy slides her tongue into her sister’s mouth, licking around the inside of her lips, then plunging it in deep.

When she finally slips it out, Carrie, woozy with lust finished her though “Please... stop delaying. Please make me cum.”

Cassidy nods. You wonder how strange it is for her that her sister just said those words. Then again, the 3 of you are so far past ‘strange’

She lays her sister down on her back and slides her panties down her long legs.

“I’ve never done this before.” Cassidy says to her sister before burying her face in Carrie’s crotch with as much confidence as she can muster.

Carrie wraps her thighs around her sister’s head and reaches down to take a handful of brown hair. Her body flails and whips around violently. You wonder when was the last time she’d gone this long without an orgasm. Ever since she started fucking? And now she’s done it for you.

Her mouth is open in permanent scream, but no noise comes out. Her eyes roll back into her head. Her hand that’s not gripping her sister’s hair pounds at the floor.

For someone who’s never done this before, Cassidy knows what she’s doing. Then again Carrie is an easy cummer.

Which her sister is learning right now. She screams, muffled at first, then loud as she pulls her face back, Carrie’s juices squirting up at her.

What a shocking, beautiful, messy sight. Cassidy covered by her sister’s wet passion.

Carrie lies limp and exhausted on the floor. And Cassidy turns her attention to you next. “Master?”
