The best part of doing it is after he cums and you suck his cock right back into your mouth, covered in its own cum. The taste of a hard cock covered in the cum you just got out of him - ummmm. And you can think about it. Think about what you just did. You made him cum. Yeeeaaaahhh! You did that, you sure did. So satisfying. You feel better now, lots better. At least until the hunger returns. Then you are back to the hunt for the next time.
