From a start working up the heat on a sexy foe, she cannot ignore what he does to her. Sensation by sensation she is distracted away from her original intent - that is to overload him with pleasure. In time, he gains the superior position. She tries to rally, being in a position of minimal energy expenditure, but he keeps piling on the good sensations.
Intentions dwindle as sensations intensify. The universe shrinks to the urgency of an approaching orgasm. Looking at his steely gaze merely intensifies the lust - so she closes her eyes - but still - he pounds her body, invading her consciousness as his cock invades her body.
She cumms - wordlessly a first time, then a second, then a third. His pace maddeningly does not vary and she feels truly helpless and buffeted by a superior sexuality.
With her forth peak - she knows she can go no farther and signals her submission with the dry words: “I give”.
A few minutes later, the victor has his time of release, spewing cum and grunting like the dominant animal he is.
