When my lascivious stepsister and I found ourselves alone, she couldn't resist the urge to seduce me. She dropped to her knees, eagerly devouring my throbbing cock with an insatiable hunger. The sight of her perfect ass bent over, eagerly awaiting my penetration, was too much for me to resist. I plunged deep into her, filling her up with my massive shaft. The intensity of our coupling left us both breathless, as I continued to pound her relentlessly. The pleasure was overwhelming, culminating in a powerful climax that left her mouth filled with my hot, sticky cum. The sight of her licking every last drop off my pulsating member left me utterly satisfied. Our passionate encounter left us both utterly drained, but completely content. The taste of our shared ecstasy lingered in the air, a testament to our unquenchable desire.
