Ruined Orgasm Videos, Please

[TheIntrepidBoyager]

Mistress is expressing interest in learning more about ruined orgasms. She's read about it and we've talked a little about it but I think videos would be quite helpful so please share links to any good ones you know of. I know it isn't necessarily rocket science but there is some technique and besides, the videos may provide motivation.

Thanks in advance.
