Michael's position was a precursor to a more intense engagement, and Betty, still basking in the afterglow of passion, seemed not yet fully recovered from her previous surrender.
When Michael lifted her legs, she was momentarily unresponsive.
As she came to her senses, Michael had already hoisted her legs onto his shoulders.
"Ah... no, don't..." Betty quickly tried to protest, realizing Michael's intentions.
Her legs were now on his shoulders, her buttocks lifted off the bed, her lower body elevated above her upper body, giving her the sensation of being upended.
But before Betty could fully articulate her protest, Michael's next move interrupted her.
Instead of penetrating her, Michael lifted her legs, then reached under to grasp her buttocks.
