My normal wank habit is 30-45 minutes of steady, controlled wanking before shooting my load and falling asleep. I could properly shoot after 5 minutes but choose to prolong the sensation. Last night I was a bit drunk and horny so just went for it. I shoot my load pretty quickly, but I wasn't fully satisfied. After a few minutes I was hard again and started wanking again. That second wank was the best wank I've had in a long, long time.
I was possessed with an urge to cum. I was wanking more furiously than I have done in years. I didn't think about prolonging or controlling it, I was focus purely on get spunk to fly out of my cock. It last about 20 minutes. By the time I finished I was out of breath and sweating liking crazy, my cock was red raw and my wrist was sore.
I'm going to be wanking like that more often. It's great to be able to stay in control, but it's also great to go wild and surrender to pure sexual energy.
