A bored teen, left alone with her friend's stepbrother, can't resist her growing curiosity. She invites him to her room, claiming she needs help with homework. But as they sit close, she notices his growing bulge and can't help but touch it. He's hesitant at first, but her persistence and the taboo thrill win him over. They start kissing, and she guides his hand to her panties, already wet with desire. He fingers her, making her moan softly, before she takes out his hard cock and sucks him off. They fuck on her bed, their moans filling the house, until they both cum hard.
