She'll warm Beth up

"Yeah, I...I wouldn't mind that," Natalie says, a little breathless.

"Go on, warm her cunt up for me," Anna says with a laugh. She's starting to step into the harness.

Nat kneels down behind Beth at the edge of the bed, the other girl wriggling her full hips in anticipation. Nat's heart is beating fast - though she'd never dream of telling Anna this, she's never really been with another girl before. {if Sluttery > 39}Just been fucked in the same room as them.{endif} Beth's pussy looks delicious and inviting, already moist. Nat licks her lips. She has some idea how this is supposed to go...leaning forward, she extends her tongue and gives Beth's labia a tentative slurp.

Beth's warm, and slightly sticky, and a little salty. And she moans as Nat licks her in a way that sends shivers down Nat's spine. She wants to hear that sound again. So she gives Beth another lick, swiping her tongue up from the girl's clit to her base, then another, then flicks her tongue over Beth's clit. Beth groans and grinds her hips back toward Nat's face and Nat, impatient, grabs her hips with both hands. She buries her face in Beth's pussy, inhaling the musky salt scent of her sex, pushing her tongue deeper into Beth's slick folds as she works gasps and shrieks out of the girl bound on the bed.

"Nice, that's super hot," she hears Anna say. There's a click and, as Nat comes up for air, she sees Anna standing nearby with her phone pointed at the two of them.

"What...are you doing?" Nat asks. Her brain feels slightly sluggish.

"Don't worry, just taking some pics for Insta. You look super hot with Beth's juices on your lips. Smile!" Nat does so reflexively, and Anna grins as she snaps another picture. "Now give me a turn, I wanna stuff the slut."

Something in Nat feels like she should object to Anna taking pictures of her eating Beth out - or at least to her posting them on Instagram - but then she notices Anna's wearing the harness she was holding earlier, and one of her larger dildos is slotted through a holster at the front. Nat's eyes widen. Is she really gonna...

"Go on, give me room!" Nat scrambles out of Anna's way, and her friend smirks. Kneeling on the bed behind Beth, she smacks the bigger girl's ass. "You ready for my cock, little bitch?"

"Yes, Anna! Please," Beth whines. Anna grins and winks at Nat, who's settled onto a beanbag.

"You a good little slut, Beth?"

"Yes! Yes, I'll be a good slut, Anna. Please, fuck me?"

"Whose good little slut are you?" Anna hisses. She's using one hand to rub the dildo up and down Beth's soaked pussylips, and reaches forward to grab the brunette's hair with the other.

"Yours, Anna! I'm your slut!" Beth pleads.

"Good whore," Anna growls. Thrusting forward suddenly, she sinks the entirety of her cock into Beth's soaked tunnel. Beth lets out a howling moan as the huge dildo stretches her, her body immediately beginning to tremble. Anna, grinning, doesn't relent until the dildo is seated fully inside Beth's cunt. Nat notices Anna grinding against the base of the dildo, rubbing herself through her jeans against the blunt end while driving it deeper into Beth. Beth begins to gasp rhythmically as Anna finally withdraws, then begins slamming her hips into Beth's again and again.

"What do you say to me, bitch?" Anna cries.

"Thank you! Thank you Anna! Thank you for fucking my cunt!" Beth gasps. Anna laughs, eyes wild with delight.

Nat is staring, mesmerized. She's never seen Anna like...this. And she's never seen a girl do that to another girl, either. The very sight is getting her all hot and bothered, and she can feel her hand drifting, of its own accord, down toward her crotch. She wants to touch herself. But...will it be weird if she does? She can't help but be turned on. Should she join in visibly? Or try to hide?
