Kneeling in front of Travis, I reminded him that he was only allowed to orgasm with permission and that that permission had not been granted. "It's time that you learned the difference between 'want' and 'need.' You wanted to come when you masturbated without permission. You didn't need to come. You only 'need' to come when I tell you that you need to come. Do you understand?" He nodded. "Good. Now, I'm going to show you what it feels like to really want to come." With that I turned on the Hitachi, setting it to a comfortable buzz and knelt in front of him so I could press the tip behind his balls, on the soft skin between his sack and his asshole. A moan came immediately to his lips. I licked my lips and flicked my tongue up along the underside of his shaft, right where it met the head of his cock. The Hitachi continued its low buzz as I moved it onto his sack and onto the base of the spine, keeping up a slow, steady pace of licks.
