Smile

Her grin was her most powerful weapon, an expression of joy and desire. It glimmered with passion, molded by love and the sensation of his touch. It mirrored her contentment and the elation of having him close.
Every curve of her lips whispered unspoken ecstasy, a language he taught her with his knowledgeable touch. And under his tender guidance, she experienced pleasures previously foreign to her. His admiration for her smile was unmistakable, driving her to continue expressing her happiness and lust for him with every beaming and sultry smile she gifted him.
