Step Sister Loves when I Fuck her Doggy Style! Huge Cock Penetrates Tight Pussy with Difficulty!

A step sister with a big ass and huge tits, who's always had a thing for her stepbrother, finally gets her chance to explore her forbidden lust. She's been watching him from the shadows, her heart racing as she imagines what it would be like to have him inside her. Today's the day she makes her move, and she's not holding back. As he walks in, she subtly drops her towel, revealing her perfect, oiled-up body. He can't help but stare, and she knows she's got him hooked. She beckons him closer, her eyes filled with desire. He hesitates, but her big, round ass is too much for him to resist. He steps forward, his huge cock already straining against his jeans. She pushes him gently, guiding him to the bed. She climbs on top, straddling him, and he can feel her wetness against him. She's so eager, so ready. She reaches down and unzips his pants, freeing his massive cock. She gasps, her eyes widening at the sight of it. She's never seen anything like it, and she's both excited and terrified. But her desire is stronger. She positions herself above him, and with a deep breath, she slowly lowers herself onto him. He fills her completely, stretching her tight pussy to its limits. She moans, a sound of pleasure and pain. He groans too, feeling her tightness around him. She starts to move, her hips rocking gently at first, then faster and harder. She rides him like a savage, her big ass slapping against his thighs. He grabs her hips, helps her thrust. She's lost in the moment, her body taking over. He can't hold back much longer, but he wants this to last. He flips her over, putting her in a doggy style position. She looks back at him, her eyes wide, her tongue licking her lips. He knows she's ready for more. He slams into her, his huge cock penetrating her tight pussy with difficulty. She screams, her body arching back. He doesn't stop, he keeps pounding into her, her big ass taking every inch of him. She's moaning, begging for more, and he gives it to her. He's so deep inside her, she can feel every inch of him. She's close, so close. He keeps pounding, his own pleasure building. And then, suddenly, he pulls out, his cock throbbing. He can't believe he's here, right on the edge. He wants to finish, but not like this. He wants her to feel it too. He rolls her over, pulls her up into his lap, her legs straddling him. He thrusts up into her, and she shrieks, her body convulsing around him. He can feel her pussy clenching, her orgasm ripping through her. He moans, his own release following. He fills her with his hot cum, deep inside her. They collapse together, their bodies still shaking with pleasure. It's been a long time coming, and they both know they'll never forget this moment.
