This is a speciality of mine and I always liken it to playing the guy like a sexual instrument. Having him loosly tied and blindfolded naked on the bed. Do ask if he has any allergies before you start.
Think of the film nine and a half weeks. Think of what you can stimulate his senses with. Feathers, leather, soft whips, silk gloves, chocolate, fruit, ice. Progress slowly and slowly build it up so that you stimulate his body first and then his nether regions. Dont forget to use your body too. I dont get naked until he is blindfolded then brush my body on his to let him know that I am now naked. I usually finish off with letting them go so they can get their hands on me or a baby oil hand job, depending on his preference.
Good luck and enjoy.
