itsPOV - Perving on your Stepsister Tiffany Tatum leads to fuck session

In a hidden corner of the house, our blonde and petite stepsister, Tiffany Tatum, is getting ready to do her yoga routine. You're secretly watching her, your heart pounding as she bends and twists with her tiny, firm tits and tight little ass. Her flexibility is insane, you can't help but let your imagination run wild. She's not wearing much, just a tiny pair of shorts and a sports bra, her feet bare and her legs toned. You can't resist the urge to get closer. As you creep towards her, she looks up, catching your gaze. Her eyes widen in surprise before she realizes your intentions. But instead of being scared, she has a mischievous glint in her eyes. You're surprised but excited. Tiffany is game. She stands up, facing you, her breath catching as you grab her. She's still a little nervous, but her body responds to your touch, her nipples hardening under her sports bra. You can't wait any longer. You push her against the wall, her back pressing against the cool surface. Your hands roam her body, cupping her tits, squeezing her ass. She moans softly, her head thrown back. You can see her wetness through her shorts. You pull down your pants, your hard cock springing free. She looks down, her eyes widening at the sight of your huge dick. You lift her up, her legs wrapping around your waist. She's so petite, so light. You slide her down your cock, filling her tight little pussy. She gasps, her eyes watering a little. But she's so wet, so ready. You start to move, slowly at first, then faster, harder. Her tits bounce, her breath coming in short gasps. She's on a high, her body moving with yours. You can feel her tighten around you as you fuck her, her orgasm building. She comes, her body shaking, her pussy pulsing around your cock. You can't hold back any longer. You come too, your cum filling her up. You pull out, her cum dripping down your shaft. You watch as she rubs it into her skin, her smile sultry. This is just the beginning of your taboo step fantasy.
