I learned at a very early age that sucking a cock isn't done properly until you finish the job. Which meant several lengthy sessions sucking, licking and taking ALL the cum in my mouth. I've nothing against the sight of creamy cum on a boys chin, but I was taught that avoiding it was a waste. Suck..take the load, swallow...then suck some more. That few seconds after the orgasm is critical to being a 'good boy'. A warm mouth gently sucking until the sensations are too much to bear, is the sign of a genuine cocksucker. That's the difference between being paid to do it...and doing it because you love it. The other thing I learned was giving properly, inevitably meant my cock would be treated the same way.
Unbeherrscht männliche Geilheit kann es auf dieser Erde nicht genug geben. Sie führt zu so vielen guten Taten. Deswegen ist Erziehung des Nachwuchses so wichtig.
