Inadvertently stripping my stepsister's underwear, I unknowingly penetrate her with my soft member until ejaculation occurs within her

In a moment of absent-mindedness, I found myself inadvertently stripping off my stepsister's underwear, my hands exploring her soft curves. The sensation of her skin against mine sent waves of pleasure coursing through my body, my arousal growing stronger with every touch. As I continued to caress her, my soft member found its way inside her, gliding effortlessly against her moist folds. The sensation was intoxicating, driving me to the brink of ecstasy. I could feel her warmth surrounding me, her tightness wrapping around my length as I thrust deeper into her. The rhythm of our bodies entwined quickened, my movements becoming more desperate as I neared the peak of my pleasure. With a final, powerful thrust, I released my pent-up desire within her, my climax filling her to the brim.
