Vincent, the lustful stepbrother, suggests a unique study method for Eva's upcoming exam. In their dimly lit room, he whips out his massive cock, offering it as a tool for her success. Eva, initially shocked, can't help but feel a warmth between her legs. She tentatively takes Vincent's cock into her small mouth, gagging as he fucks her face. Vincent then bends Eva over the desk, her petite frame struggling to contain his size as he pounds into her. Eva's pussy stretches to accommodate Vincent's huge dick, her wetness coating his shaft as he fills her with cum, leaving her dripping and gasping for breath.
