4 Hands... 2 Sisters

Zoey and Gia sprawl on the couch, going over next week's massage exam. Gia brags about kneading thighs crammed with muscle and steel bone. Zoey shoots back that backs are her thing-strong, breakable, and kind of mysterious. Their phones ping together. Gia reads first: her buddy ditched. Zoey checks hers-her guy flaked too. No practice dummies in sight. Gia snaps her fingers. "Us?" Zoey squirms-step-sisters aren't supposed to oil each other. Gia rolls her eyes, reminds her they're not blood-related and there's no time to hunt replacements. Zoey caves, and they drag the table out. Zoey asks who strips first. Gia grins and tells her to peel and lie down. Zoey shimmies out of her clothes, face-planting onto cool vinyl. Gia slicks her palms, swoops straight for Zoey's fat ass. "That part?" Zoey yelps. Gia claims stress collects there, palms gliding over slick curves. Zoey sighs, gives the green light, and melts as her sister kneads glistening cheeks. Heat surges. Too much heat. She blurts that she should flip. Gia shifts to Zoey's tits, slides lower, fingertips brushing Zoey's slit. Zoey grabs her wrist. "Whoa." Gia shrugs, asks why not. Zoey flips the script: if it's innocent, Gia can get naked and switch spots. Gia hops up with zero hesitation. Naked, she stretches out while Zoey drizzles oil and follows the curve of her sister's waist down to her tight rear. She pours a river over Gia's butt, gripping each cheek like dough. Gia groans that the angle's even better from her back and flips, spreading wide. Zoey's tongue dives in, ring tickling the swollen clit until Gia wails and shudders through a long, wet orgasm. They aren't calling it a study night yet.
