As soon as the door closed behind his stepfather, Lex leaned in close to his stepmother, Sarah. Their bodies brushed against each other, and Lex could feel Sarah's heart racing. She looked up at him with eager eyes, her lips parted slightly. Without saying a word, Lex pulled Sarah's dress up over her head, revealing her lacy black bra and panties. Sarah gasped as Lex's hands slid down her waist, unhooking her bra before sliding it off her arms. He cupped her large breast in his hand, kneading it gently as he leaned in to kiss her neck. Meanwhile, Sarah reached between them and unzipped Lex's pants, freeing his hard cock. She gripped it firmly in her hand, stroking it as she moaned softly. Leaning back, Lex pulled Sarah against him, his hard-on pressing against her stomach as he kissed her neck passionately.
