A Tale of Kasey and Casey

Kasey and Casey grew up attached at the hip. Same house, same boys, same secrets. Then Casey vanished. She didn’t just ghost her step-sister. She traded everything for one man’s rules, one set of hands, one brutal, perfect way to serve. Now she’s spread on his bed, arms and legs knotted in rope, heels barely steady beneath her. Clamps bite her pussy lips to those heels. Every tiny shift tugs. More clamps pinch her nipples hard. Drool leaks past the ring gag. She waits, breathing through it, trying to stay upright. Derrick walks in with a crop and no mercy. He fucks her face until spit runs down her chin, denies her when she’s close, then flips her into a pretzel tie and drives straight into her ass. He pounds her like he owns every inch. The bell rings. He sends her to answer it. Kasey stands there, pissed off and half-relieved. Casey opens the door naked, marked, trembling. Before she can explain, Derrick shows up and Kasey walks. Later she sneaks back, watches through the window, sees her sister getting taken apart. Fury wins. She storms inside and orders Casey out. Casey shuts her down fast. One choke hold, one choice: stay and learn or leave for good. Kasey spits and curses, but her clothes come off. Her ass turns red under Casey’s hand. Derrick shoves his cock down her throat and Casey keeps swinging the flogger. When he pushes into Kasey from behind, she begs to come inside Casey’s cunt. Derrick makes her earn it. Then he ties Kasey tight, clips a vibrator to her clit, and fucks her while Casey waits one wrong twitch away from the TENS unit. Kasey breaks, Casey pays, and Derrick unties them both. Next lesson is posture. Casey holds a tray in one hand, a toy in the other, while Kasey rides Derrick’s cock in her ass and yanks the zipper lines off her sister’s skin on command. They trade places, trade holes, share him between them until both are shaking. Kasey’s back in the house. Back under the same roof. Back where she belongs.
