The pulsing told Xavier he was getting closer to cumming. Which meant he would be able to taste the sexy demon's "cream" or cum. He moved his head up and down. Still constricting his throat then loosening it then constricting it again. Sucking hard on him. Dragging his teeth over him as he sucked. Still fondling and kneading the balls like they were treasured jewels. He heard the mewing and purred more. So exciting. He enjoyed hearing those sexy sounds coming from his sexy demon. Well technically blake's sexy demon but he was part of blake so his in thus effect. He wanted to taste what he felt pulsing within the shaft in his mouth. Sucking even harder.
