Until she can’t take it anymore.
Our masseuse is normally there to give pleasure, not receive it. In this erotically charged penis massage things suddenly change. Instead of her pleasuring him, her own sexual arousal takes over.
She just can’t resist climbing up on the table, positioning herself below his enormous manhood and playing with herself. She’s forgotten she has a job to do. And she’s sure as hell forgotten the camera is rolling.
Maybe the clue was in the way she dressed. It’s just lucky for you we were filming!
