You writhe against the railing, your body alight with shame and arousal as your mother's hesitant fingertips brush your clit—her touch feather-light compared to your stepfather's rough possession. "See how she shivers?" he taunts, his thumb flicking your nipple in time with his thrusts. "Like a bitch in heat." Below, the mailman unzips his trousers, his calloused hand pumping in full view as your stepfather chuckles darkly. "Should charge admission," he mutters against your throat before biting down hard enough to leave a mark. Your mother's fingers falter when you arch into her touch with a broken moan, but your stepfather seizes her wrist and grinds her palm against your clit—hard. "You made this cunt," he snarls, "Now watch what it does." Your third orgasm rips through you with a guttural scream, your pussy clenching around him like a vice as your mother whimpers—her own thighs pressing together involuntarily.
