Elias Cash, the studious stepbrother, offers to help his blonde stepsister, Kait, with her homework. As he explains the answers, Kait's eyes wander, fixating on Elias' growing bulge. Seizing the opportunity, she leans in, her small tits pressing against his arm, and whispers, "I know another way to get an A." Kait's slender fingers unzip Elias' pants, revealing his throbbing cock. She eagerly takes it in her mouth, her lips stretching to accommodate his size. Elias grips her blonde locks as she expertly sucks, her tongue swirling around his shaft. The room fills with the sound of wet slurps and Kait's muffled moans, her face a messy canvas of saliva and precum.
