Orgasm control is probably one of my oldest and earliest kinks. I learned about edging in fanfiction (thanks ff.net!) and was pretty much hooked.
It’s a kink for me though, just like flogging or bondage, and isn’t something I immediately think about when I think about D/s. It definitely plays into that control element that I love and I’ve started seeing it more from a desire to please my top rather than what I’m getting out of it. Daddy gets plenty of sadistic pleasure out of ordering me to cum in front of other people though.
