Sandra is definitely the dom on the stage. Scarlett naturally became the sub not only because she is shorter and had to look up, but she definitely took the woman's role during the kiss, arms go from waist to hips and Sandra comes straight in with her hands pulling Scarlett's lips to a sensual conclusion.
Sandra must have a wild side judging by her recent relationship with Jesse James, so we know she has a rough alter ego that may prove to be more than young Scarlett can handle.
A defiant Scarlett may surprise Sandra in a more private setting. Scarlett wears a deviant little grin during many of her exploits, add to that her age, the never ending public image she needs to maintain and her world class breasts, I'm more than positive Scarlett carries a caged aggression in need of a release. Sandra's womanly assets would wined up floored in a collection of her own sweat, Scarlett on top using her thighs as blinders to help a stunned Sandra focus her attention "up" to make sure Scarlett has full attention of a teary eyed Sandra B.
