My Stepsister made me really Horny while Playing Video Games

Imagine yourself in the game room, the lights are low, the atmosphere is charged with a mix of anticipation and tension. Your stepsister, a gorgeous brunette with a big, curvy ass, is engrossed in her game. Her feet, clad in tiny socks, twitch with excitement as she plays. You, unable to resist her allure, decide to make a move. You sneak up behind her, pushing your hard-on against her. She giggles, feeling your bulge, but continues to play. You can't help but get closer, your hand reaching out to grab her thigh. She looks up, her eyes meeting yours, a playful smile on her lips. You lean in, whispering in her ear, "You're making me really horny, sis." Her eyes widen, her game forgotten for a moment. She turns around, her hands going to your shirt, pulling you closer. You can feel her breath on your neck, her hands exploring your body. She looks up at you, her eyes filled with desire, and says, "I thought you were just going to watch me play." You smirk, "Well, now that you've started, you can't stop." And so, the game begins.
