The stepbrother, unable to resist his insatiable desire for his stepsister, sneaks into her room while she's asleep. He undresses and crawls towards her, his cock already hard. He gently wakes her up, kissing her neck and whispering dirty words in her ear. She moans softly, not fully awake but aroused by his touch. He pushes her pajamas aside, revealing her wet pussy, and starts to lick it vigorously. She wakes up fully now, groaning in pleasure as he relentlessly pleasures her. He slowly enters her tight pussy, filling her up with his hard cock. They both groan loudly as he begins to thrust deeply inside her. He slaps her round ass as he fucks her harder, making her moan even louder. She cums hard around him, screaming her pleasure.
