We’ve all had one at some time or other usually unintentionally. You build up and pull back to that orgasm tip over point so many times that if you’re not careful your orgasm will actually fizzle and die. In the case of cuckolding or just male control you do it to drain the balls and that’s it. The ejaculate will actually just pour out and there will be no muscle spasms or fun stuff to go with it.
Most men don’t want a ruined orgasm but their Mistress doesn’t want them experiencing pleasure for a variety of reasons. One reason is it keeps the focus off their cocks and on the Mistress where it should be.
Is it bad for you, no. It won’t do anything harmful it just doesn’t feel good because you don’t experience a full pleasurable orgasm.
There is no perfect way to perform a ruined orgasm either. You need to know your submissive well enough to be able to feel with your hand when he’s getting to that edge obviously. Never go by his expressions or what he might be saying cause let’s face it he’ll try to get that one slip over the edge. Like everything else it just takes practice. You can also use prostate massage the same way.
