Moments during an impact scene when you dance on the edges; giving enough pain to hurt but, not to harm a treasured masochistic sub. Watching the body they've given to you begins to struggle, fighting between escaping the blows and arching into them.
A delightful dance performed as the sensations overwhelm their last bits of self-control.
In those moments, your heart beats faster, your mind focuses on the bond of trust given to you, and the world shrinks to the space between you and your sub.
In those moments, the time spent learning, practicing and committing yourself to being a responsible Dom is rewarded. Watching their body quiver and struggle. Hearing their screams or gagged moans as the sensations and exchange of power overwhelms them.
In the moments afterward, releasing the bindings, seeing their eyes looking dreamily into yours and feeling their body collapse contently into your embrace. Priceless.
