Under the guise of watching a horror film, step-siblings engage in a taboo game of seduction. The teen sister, her heart pounding from fear and excitement, reaches out to grasp her brother's hardening cock through his jeans. He stiffens, not from the movie's scares, but her brazen touch. She leans in, whispering, 'Do you want me to suck it?' as the film's screams echo around them.
