With the on-line sub I had for over five years I used both what we called 'near-cums' and forced orgasms as punishment. I set a strict regimen for when she was to bring herself to almost cumming. The very first thing in the morning as she was sitting on the pot, but before her morning pee. During her lunch break in the ladies room. (I think the keeping quiet part of that was almost as bad as the near-cum!) The instant she got home from work. (She was required to strip just inside the front door of her apartment and stay nude constantly when alone at home.) And then again later that night as I watched her on cam.

Now this was punishment to her, not only because she hated to not finish what she started along with the, shall we say physical discomfort, but in her mind she knew it was because she had displeased me and that made it even worse. This was her atonement. But, I know you're asking about the forced orgasm part. When I felt that she was now properly contrite she was allowed relief, but on my terms!

As she sat before her cam I had her place a rolled up towel between her opened lips and place the infamous egg down there pressed tight against her clit. Then I sat back impassively and watched and counted the number of orgasms she had. After four or five days of being denied her clit was now hyper sensitive and being forced to cum as many as ten times without a break in between and not being allowed to remove the egg from her clit was absolute agony to her. The lesson had been learned and we only had to do this maybe three times in the five years we were together.

I guess you could say it was effective. *L*
