Alex Blake and Alex Jett, step-siblings bound by blood and taboo desires, find themselves drawn to each other in the quiet of their shared home. Alex B, the elder, can't help but notice Alex J's growing manhood, while Alex J is captivated by his stepsister's womanly curves. One fateful evening, they collide in the hallway, Alex J's hard-on pressing against Alex B's thigh. They freeze, hearts pounding, then retreat to their respective rooms, but the tension lingers. That night, they each pleasure themselves, fantasizing about the other, their moans echoing through the house.
