Incest Seduction/Rub the oil into Kim's ass

From Create Your Own Story

"Your wish is my command," you state with zeal, slapping your hands onto your sister's ass. Even as you start working your hands around her bum, Kim can't hold back a chuckle at your ridiculous initiation. But she isn't laughing for long as you rub your hands over the full width of her ass. Your fingers push her towel even higher, exposing more and more of her lower back. Your thumbs dive below each cheek, lifting them into the air slightly and helping you peak on the fingers she has pressed against her pussy.

"Um, Ry. There's a lot... in... between..."

You respond without words, gripping her cheeks and spreading her ass wide. You stare at her asshole for a moment, tiny pale and pink, and the globs of oil sitting in the middle of her ass. Kim shifts her fingers a little, clearly embarrassed by her own request.

With one thumb, you gently brush from her the top of her cheeks down across her taint. Her pretty little asshole puckers as your thumb slides over it. You slide back in the opposite direction, collecting and redistributing much of the oil with your digit. A small glob runs amok however, settling just below her hole. You bring an index finger down to the glob and push it up. Your finger lightly presses against Kim's pink star. That tiny bit of pressure gets her attention though. One of her legs jerks a few inches to the side and a long exhale shudders as it leaves her lips.

You continue to kneed your sister's bum, more than happy to have her joyously firm ass in your hands, but can't stop yourself from dipping deep between her cheeks and stroking the length of her crack over and over. Little by little you push more oil toward your sis's fingers. It oozes underneath her hand and you watch intently as she is forced to rub it in to herself more than once.

This was never about a massage. Play with Kim's asshole some more.

Continue moving higher. There's still plenty of towel in the way.
