It’s only a half hour into it, and Camille rides Jack like a surf boarder rides a wave. Jack controls the first seven hours of the encounter but she rides the experience, flowing with the waves. He uses her however he wants.
For the next three hours, it seems that she regains the initiative and things wax and wane between the two. My mutual agreement - they sleep the rest of that night.
The next day, he again aggressively takes control, bringing her to climax, but between his bouts of assertiveness, she makes him cum - just as much and just as hard.
By noon, both feel the soreness of overuse, but Camille feels it the more, finally getting her penultimate and ultimate cumms from the still hard stud.
She did her utmost, but he bested her in this primal battle of the sexes.
