Your Stepsister's In Charge

Penny's about to run errands and lays it out for the girls before she leaves. Listen to your big sister, she tells Summer, like she always does. Door shuts. Five seconds later Aften's already strutting around like she runs the place, barking orders like Summer's her personal bitch now. Summer rolls her eyes but nods, knowing how this goes. First thing Aften wants is a little dance—then she says strip. Clothes hit the floor and both girls are breathing a little heavier, nipples stiff, shorts getting damp. Aften pulls Summer in, shoves her own tits forward and tells her to grab them, then suck. Summer latches on, tongue working circles while Aften groans and grinds against nothing. Heat's climbing fast. Aften lies back and drags Summer on top so they can sixty-nine, tongues flicking clits, hips rocking, muffled moans turning the living room into their own filthy circus. Aften gets a wicked spark and bolts upstairs, coming back wearing nothing but a strap-on harness. Summer's eyes go wide but she's game—on all fours in seconds. Aften lines up, slams in deep, fucks her in hard, hungry strokes while Summer claws the cushions. Then the front door clicks. Penny's back early, catches the whole show, arms crossed and eyebrow up. "Power trip much?" she says, half smirk, half scold. She drops her bag and steps in close. "Guess it's time you two taught big sis a lesson." Clothes fly. Summer pins Aften's wrists while Penny takes the strap, works it into her from behind, every thrust knocking that cocky attitude loose. They're a sweaty tangle of payback and payback-again, and nobody's errands getting done anytime soon.
