Step Sister Fucks me when we are Home alone

Imagine you're standing in the living room, feeling the warmth of the afternoon sun as it filters through the windows. You're home alone, and suddenly, you hear footsteps. It's your step-sister, back from school early. She's wearing that tiny skirt that makes your heart race, and you can't help but notice her full, round ass. You're about to put your headphones back in, but she stops you. "Hey," she says, her voice a sultry whisper. "I've been thinking about something." You look up, and she's already unzipping your pants, her eyes locked onto you with a hungry look. "I want to taste you," she says, her breath hot on your ear. You can't believe what's happening, but you don't want to stop her. She takes your cock out, her hand wrapping around it, and you can feel her fingers teasing you. She leans down, her big, full lips wrapping around your shaft, and you can't hold back a groan. She's sucking you like a pro, her mouth feeling incredible. You're watching her through the window, feeling her hair brush against your thighs. The sight of her big ass moving as she sucks you off is mind-blowing. You're about to blow your load, but she pulls away, a smirk on her face. "Not yet," she says, her voice a low purr. "I want to fuck you." She stands up, her skirt falling to the floor, revealing her wet, ready pussy. She pushes you down on the couch, straddling you. You can feel her warmth as she slides onto your cock, her big ass bouncing as she rides you. You're watching her through the window, seeing her big tits jiggle as she moves. The sight of her is so hot, and you can't believe you're actually fucking your step-sister. She's grinding down on you, her pussy tight and wet. You can feel your orgasm building, but she keeps you on the edge. She leans down, her hair brushing against your face, her lips just inches from yours. "I want to feel you come inside me," she whispers, her voice a low growl. And then, you're coming, your cock pulsing as you fill her up. She grinds down on you, milking you, and you can feel her own orgasm building. She's crying out, her body convulsing as she comes, her pussy tight and wet around your cock. You're both panting, your bodies slick with sweat. She leans down, her lips brushing against yours, a soft kiss. "That was amazing," she says, her voice a low purr. "Let's do it again sometime." You can't believe what just happened, but you know you won't be forgetting this anytime soon.
