Bent forward, arms behind the back to show off her breasts

With such a gorgeous face, body, and disposition to please, why not pose her a bit more? Since this is "submission," make the poses outrageously exposing : arms high to show off her breasts, standing at attention to show off her ass, legs apart, then bending over, presenting her breasts, dangling her breasts, holding her labia open, make her play with herself until she's about to cum, then direct her through the same poses.
