Kelly Greene, a youthful brunette, finds herself tossing and turning in her sleep, haunted by erotic dreams. Her stepbrother, J Mac, hears her cries and enters her room, finding her restless and vulnerable. As he tries to comfort her, he can't help but notice her perky small tits and shapely body. Kelly, awakened by his presence, feels a strange attraction to him. They begin to explore each other's bodies, starting with a passionate kiss. Kelly eagerly takes J Mac's big, throbbing cock into her mouth, deepthroating him with skill. She then straddles him in cowgirl position, her tight pussy sliding down his length. They switch to doggystyle, J Mac's strong hands gripping her hips as he pounds into her. The night ends with them entwined, spent, and questioning their taboo actions.
