Teaching Skyler

Skyler looks fresh off the playground with those reckless eyes, but here she is, biting her lip as she tries to shove her own fist up that narrow, barely-legal cunt. The knuckles catch, the skin stretches white around every joint. She swears, pushes harder, grunts like someone half trying to hurt herself on purpose. Petra kneels behind her, slick to the wrist in lube, then slips her fingers in alongside Skyler’s. Two hands working in tandem now, she spreads the younger girl open, guiding Skyler’s fist past the stubborn second knuckle until, with a wet pop and a hiss, the whole fist finally slides home. Skyler’s stomach jumps. Petra curls her fingers, pressing down from inside, turning the stretch into something deliberate and deep until Skyler starts panting through clenched teeth, hips twitching like she’s being rewired.
