I think I know you from another forum good to see you

Sorry that I need to disagree with you, but cum-on-demand does not necessarily need any physical stimulation previously. In a D/s relationship, my sub was 'trying it on' with bratty behaviour. Of course, I had a number of options, but i used the "Cum for me immediately" and not only did she do so, but it was a wonderful tool to remind her who was in control of her mind and body.
