In the dim closet, a bandit-like brother sneaks up on his sister, pressing his hard cock against her from behind. He grunts, "Shh, don't move," as he unzips his pants, revealing his thick, veiny cock. She gasps, feeling his warmth against her ass. He roughly pulls up her skirt, rubbing her pussy over her panties before pushing them aside and plunging into her wetness. She bites her lip, trying not to moan as he fucks her hard and fast, his heavy balls slapping against her clit.
