In a cramped, dimly lit room, a heated exchange between cousins escalates. She taunts him, "You're all talk, primo." He responds with a stinging slap to her ass, leaving a red handprint. She gasps, her body betraying her with a surge of lust. He unzips, his cock springing free. She backs onto him, guiding him to her slick entrance. He grips her hips, driving into her with force, their bodies slapping together as he fucks her doggystyle, her ass bouncing with each thrust.
