Sister's Ride: Saddle Up, Big Brother
In the dimly lit study, Michelle and Brian sit close, their thighs touching as they pretend to study. Unbeknownst to Brian, Michelle's mind races with lustful thoughts. She leans in, her breath hot on his ear, whispering, "I've been bad, Brian. I need you to punish me." He tenses, then turns to face her, his eyes filled with a mix of shock and desire. She takes his hand, guiding it under her skirt, showing him how wet she is. He hesitates, then begins to stroke her, his fingers moving in and out of her slick pussy. She moans softly, her hips moving in rhythm with his hand. Suddenly, she stands, pulling him up with her. She bends over the desk, hiking up her skirt, offering herself to him. He unbuckles his pants, his cock hard and ready. He enters her, fucking her hard and fast, their bodies slapping together, their moans filling the room.
