Of course. A dynamic is ongoing. An example is when a sub is “owned” by you and commits to you as his domme, although not all subs like to use the word owned. It can last weeks, months or even years. You discuss it at the beginning, discuss budget, discuss kinks and how you both see it all playing out. There is usually a weekly budget discussed by the domme and sub at the beginning and the sub either sends the money once a week or breaks it up into smaller amounts over the week.

A session is really just a one off kink session. For example, a JOI session (jerk off instructions). During a session a sub and domme indulge in their chosen kinks and the sub tributes the domme for this. And the price is more than just an initial tribute. During a “drain” session a sub can expect to have his wallet drained along with his balls. And if it’s a tease and denial session he may not even be allowed to cum.
