The stepdad, a powerfully built alpha male, pins his young, lithe stepson down on the bed, his strong hands gripping the boy's wrists. The stepson squirms, his ass pressing against the stepdad's throbbing cock, trying to entice him. The stepdad grins, his eyes never leaving the boy's. "You want this cock, don't you?" he growls. The stepson nods, biting his lip, his breath coming in short gasps. The stepdad releases one of the boy's wrists, using his hand to guide his cock into the boy's ass. The boy gasps, his body tensing as the thick cock pushes into him. The stepdad leans down, his breath hot on the boy's ear. "You're such a good little cock slut, taking daddy's big cock like this," he whispers. The boy moans, his ass clenching around the stepdad's cock as he begins to thrust, his body moving in sync with the stepdad's. The room fills with the sound of their bodies coming together, the slapping of flesh, the moans of pleasure, and the dirty talk that pushes them both closer to the edge.
