After hours of battle and multitude of peaks, the old champ has been KO'ed by cum.
The new champ, worn as she is, knows how close this was. She needs to impress something dramatic upon her defeated rival. More than a KO, the idea is to break the old champ.
The new champ had learned her opponents body well. Even in this state, the sure signs of another climax are building.
If new champ's lucky, old champ will revive during another peak and pass out again, underscoring a relentless nature.
