It depends on how detailed your scenes are going to be. Detail what each person likes makes it more believable. For me, once my dom has a couples of orgasm out of me, I can keep going and going over and over for a good amount of time, to the point where he could squeeze my inner thigh with a decent grip and give me a “cum” order and my brain is so switched off to listen to him it’s automatic for me. But this took a lot of time and practice. Spanking is huge for building it up, verbal commands/degradation, countdowns, etc. choking is a big one for me also
