The safe word conversation is the best part of this story/relationship.... And there are more than one reason for it.
trust factor... (Already mentioned but repeating)
The way you weaved trust in this is total love... When I read for first time I was like 🥺🥺
Not only does it break stereotypes about the "duties" of a woman towards husband and marriage.... It also challenges the belief that the woman cannot chose to stop the husband---- The urban myth of "point of no return" that is often used to justify what I can only call in-the-moment selfish choice of need of one over comfort of another.
By giving her the power (with these words) and taking the responsibility to stop himself.... Aryan also breaks the usual stereotype of how we see a Dom.
It gives us an important take away that for a good Dom... Control is more about responsibility than power.
On a lighter note: someone's topping the list faster 🤭
