On a 7-9, Sarah will fuck you if you turn her on

Sarah sits down on her bright pink bedsheets next to her blonde sister Shasta. Shasta is lying down naked and relaxed after you gave her an orgasm by making her giggle.

"I want to see you coming hard too," you tell Sarah. "While I look into your eyes from an inch away, while I'm deep in your pussy. Would you like that?"

Sarah blinks, still trying to clear her head. She takes a deep breath, then another. She runs her hands through her chestnut-brown hair, which turns into a repeated motion, sensually caressing herself over her head, neck, and shoulders. "Oh, you mean?" she says, your question connecting to an answer. She smiles broadly. "I think I'd like that. But first I've got these tingles all over, I guess. Could you kinda help smooth them out?" She runs a hand down each arm, down her sides, down over her breasts and abdomen. "I can't reach my back, y'know?"

"Okay," you say. You start caressing Sarah, following her rhythm of long, slow strokes. She sighs as the waves of tingles over her skin smooth themselves out.

"Mmm, that's good," Sarah says. "Do my back more."

"Easier if you lie down," you say.

"Okay. Move over, Shas," she says.

"Mmph?" Shasta says. But somehow she understands and slides over on Sarah's bed.

Sarah lies down on her tummy, wincing when her nipples slide over the hot pink bedsheets. "Oooh!" she says.

You sweep your hands in long, light, smooth caresses down Sarah's back, from her shiny chestnut-brown hair down her back, over her buttocks and down her legs.

Sarah coos in pleasure. "Yes, more, more," she says. "Ahhh."

After you-don't-know-how-long of this, Sarah turns to look over her shoulder at you.

"Hey, didn't you want to...oh yeah, fuck me?" she asks. "How about now?"

Sarah giggles as you guide her up onto her knees.

"Ooh!" she cries as you brush your fingertips lightly over her pussy lips, deep pink and swollen with arousal. "How you gonna see my eyes if I'm on my knees?" she asks.
