Big Dick Birthday Surprise

Upon arriving home, I discover my stepsister in a state of solitude and dismay on her special day. It seems her companions have completely abandoned her. Wanting to lift her spirits, I offer her solace, only to learn that what she truly longed for was some intimate celebration.
Feeling the responsibility as a caring step-sibling, I am more than willing to fulfill her desires. She eagerly takes charge, eagerly taking my manhood into her mouth, reveling in every moment before straddling and riding me with fervor, showcasing her ample posterior. Best wishes on your birthday, Natana Brooke!.
