I think you should have done some breath play when she was gasping for air trying to stay awake and what I think was her trying to not have an orgasm. The Breath play would have made her forget that she is trying to control her orgasm, and made her have one.
Don't get me wrong I like the model and her performance.
What I am trying to say is the Vibrator then squirt combo. It is over exploited especially with Yum-Ra series with Rain DeGrey. Jaded? true it may just be me from the look of the other comments. Peace
