With both he will do as she wishes and he has no idea of what will happen next.

With Femdom a major component of what make this moment special is her enjoying her power - this is about her feeling dominant and her enjoying his submission.

FemDom is well suited to a naturally dominant or bossy woman.

With Devotional Sex her control of their sexual activity has enabled this moment. But what makes this moment special is her enjoying her Knight sexually desiring her.

If this were "normal" sex then he would probably get on top of her and enter her in just a few seconds. But with Devotional Sex she can pause this moment of desire. This erotic connection is more tantra than dominance. She enjoys looking at his erection, she enjoys the desire in his eyes.

And with Devotional Sex she loves that his desire will be channeled into sexually pleasing her - it is her choice as to whether or not she has him enter her, or perhaps this session she will have him eat her to orgasm and that is all. The thrill for her is not that she can make him do this, but that she will enjoy being pleasured the way that she wants by a man who enjoys pleasuring her.

With Devotional Sex this moment is 20% kink (her power enabling the moment) but it is 80% tantra (a celebrating of erotic desire).

One thing that makes Devotional Sex different from FemDom is that many non-dominant, non-kinky women may enjoy having a Knight.
