Out of the corner of his eyes, Caius saw the ripples of sound become musical notes that always burst into more colorful ripples and it was such a beautiful sight. He looked up then at Eloise's face and her eyes were closed as more moans escaped her lips leading to more ripples, more musical notes that burst but she didn't seem at all aware. Like her magic was exploding from her with little to no control.
The moment Eloise opened her eyes, the ripple reactions around them stopped. She saw Caius looking at her, her nipple still in his mouth as he sucked up even more of her tit. She wrapped one hand around the back of his head as she breathed in and out and arched her back so much, that the encouragement that he should continue what he was doing was so clear.
