In the dim light of the closet, I explore the forbidden, my heart pounding. Her panties, silky and warm from her body, become my focus. I rub them against my cock, feeling the smooth fabric, the hint of her warmth. I'm rock hard, aching. I free myself, my hand wrapping around my thick shaft. I stroke, the image of her in these panties, her pussy dampening the fabric, driving me wild. I can't hold back. I cum hard, my load filling her panties, marking them as mine.
