Poker Night Punishment with my Bratty Step Sister

The tension in the house was electric, all thanks to a few hands of poker and my bratty stepsister’s massive ego. Cassie had been strutting around all week, bragging about her "poker face," so when we sat down for a casual game in the living room, I knew I had to take her down a peg. The stakes were simple: if she lost, she had to obey my every command for an entire evening. Of course, she agreed, flashing me that cocky smirk that drives me absolutely crazy.

One by one, my royal flushes and clever bluffs chipped away at her confidence. I watched her pout and squirm, trying to read my eyes, but it was futile. When I finally laid down my winning hand, her face went from smug to utterly speechless. She slammed her cards down, trying to weasel out of the deal, but a deal is a deal. I reminded her of the rules, my voice low and firm, as I leaned over the coffee table. Her cheeks flushed a deep crimson, but she knew she was trapped.

The punishment was simple but deliciously wicked. I ordered her to change out of her comfy clothes and into the tiny, sheer lingerie I had stashed away for a "special occasion." Her hands were trembling as she slipped into the lace, her eyes wide with a mixture of humiliation and, if I’m being honest, a hint of arousal. Standing nervously in the middle of the room, she was a vision of taboo temptation. I made her dance for me, slowly, teasingly, while I watched from the couch, my cock already straining against my jeans. Her skin was glowing under the soft lamp light, and every nervous giggle and shy twirl made my need for her more intense. This was about teaching her a lesson, but right now, all I could think about was claiming my prize and showing her exactly what happens when you lose a bet to your older stepbrother.
