The host did correctly incorporate paying attention to the balls when rimming. However I believe that a good rim job can also incorporate the cock (separate and apart from the balls as mentioned). One way is to have your partner some to the end of your bed and kneel. You now have access to a panoply of toys to work on (hopefully to your partner's delight): his balls, shaft, and hole. Go to it. If, however, you have a bed with footboard, you will have to do it completely with both of you on the bed. No problem but you have to pull his shaft backward. This may be harder because it will be really stiff cause you are doing such a good job on the rim. At any rate, pay attention to the video and your partner will pay you back in ways that you won't forget.
