Fucked Step Sister, so as not to Watch Porn!

Imagine the little sister you never knew you had, the one that's hot, wild, and just a bit naughty. She's been living with her stepbrother for a while now, and the chemistry between them is palpable. One night, when everyone else is asleep, she can't resist anymore. She slips into his room, her heart racing with anticipation. As she crawls into bed beside him, she gently shakes his shoulder, whispering his name. He stirs, his eyes opening to the sight of her, his step-sister, his little secret. She teases him, her hands running through his hair, her breath hot on his ear. "Baby, I've been watching you," she whispers, her voice like velvet. "I can't take it anymore. I need you." He's taken aback, but the look in her eyes is too much to resist. He pulls her closer, his hands roaming over her curves, feeling the softness of her skin. She grinds against him, her body already on fire with desire. He flips her onto her back, his hands gripping her firm, round ass. She moans, her body arching off the bed as he spanks her, hard. The sound echoes through the room, a mix of pleasure and pain. He does it again, and again, until her ass is glowing red. Then, he slides inside her, slow and deep. She gasps, her eyes widening as he fills her completely. He starts to move, his hips thrusting against hers, his cock sliding in and out of her wet heat. She wraps her legs around him, pulling him closer, her nails digging into his back. He fucks her hard and fast, his breath coming in ragged gasps. She's screaming his name, her body convulsing as she comes, her pussy clenching around him. He pulls out, his cock glistening with her juices, and he finishes inside her, filling her with his hot cum. She moans, her body shuddering as she feels him inside her, his cum spilling out of her pussy. They lie there for a moment, their bodies entwined, their hearts racing. Then, they whisper to each other, their voices barely audible, "Don't tell anyone."
