"So, Emily, you still prefer whole milk?" Jake asks, trying to keep his voice steady as his sister's cleavage catches his eye. Emily smirks, knowing full well the effect she has on him. "Always, Jake. It's thicker, creamier," she purrs, licking her lips. Jake swallows hard, his cock twitching in his pants. He watches as Emily takes a sip of her coffee, her lips wrapping around the rim of the mug. He can't take it anymore. "Emily, I need you," he growls, standing up and pulling her into a fierce embrace. They stumble to the couch, hands exploring each other's bodies, their clothes falling away, revealing the siblings' naked, eager forms.
