Trapped in the confines of their strict home, siblings Emily and Luke turn to each other for forbidden comfort. Emily, her heart pounding, tentatively reaches out to stroke Luke's cock through his pajamas. Luke, surprised but eager, guides her hand, teaching her the rhythm he likes. They freeze at the sound of their mother's footsteps, quickly separating. Later, they reconvene, this time with Luke's cock fully in Emily's hand, her innocence lost in the heat of their taboo embrace. Their passion builds until they're forced to stifle their moans, their bodies trembling with the thrill of their secret, sinful union.
