Tattooed Derrick, the head of the household, finds his stepsisters Casey and Kasey tied up in their shared bedroom, their roles reversed for once. With a wicked grin, he decides to play along, forcing them into a family threesome they won't forget. Casey, always the submissive one, begs for his cock while Kasey, tied spread-eagled on the bed, watches hungrily. Derrick teases them both, his thick, veiny cock slapping against their faces before he fucks Casey hard from behind, her screams of pleasure filling the room. Kasey, desperate for her turn, whimpers until Derrick unties her, only to tie her up again, this time with his cock deep inside her.
