Each day mistress waited to see how long I stay hard without the tube, today it was over six hours. It is quite comfortable now I am used to it. Mistr...ess has ordered a new longer tube with an internal battery powered pump to maintain the vacuum, she thinks that after a month pumped in the tube, and the effects will be almost permanent. While the tube was off today, she told me to masturbate to her ass, when I was excited my cock was no bigger and when I came, it did not shrink back, my mistress. Wasn't it?I couldn't help to continue imagining that porn scene. She sucked that cock all the way up to the head, and then licked it all the way down to the balls. Stroking the shaft as she started sucking on the balls. I could imagine it so vividly, it was like I could feel it happening to me! Sucking on my balls and stroking my cock, with such a tight grip but excruciatingly slowly. Feeling each inch of her sliding all the way up & down my length. Looking up at me as she jerked me off. She. " Oh. Well, tomorrow, you know, we're supposed to go --"I said quickly, "Uh, somebody else has to use this phone, so I should get off." Oh." Anyway, I'm fine, and... I'll, uh, I'll call back if you want. Later." Okay, just thought you might want -- " Have to go. Really." Behind the far wall behind me, I heard the water stop running."Okay. I just wanted to know if the reading went well." Oh, yeah. It was great, really great." So who won?" They, uh, they don't know yet." I looked at the door into. He said.The conversation changed then to general chit chat, the news, the weather, how he would only have a garden for another 6 years or so, before the sea takes it. It was nice.The conversation sort of petered out, and we both just laid there relaxing and taking in the last of the evening sun. Out of the corner of my eye, I noticed that Sid had started to gently stroke his cock. I turned my head, trying not to make it too obvious, and watched, as very slowly Sid’s cock began to grow and.
