Prime era Mike, back when his site Nympho was new, would've made one of the best scenes of Shawna's career with her. The angles and direction would be right, and he'd make sure he'd get her to squat fuck him for a decent amount of time, it's always been his favourite position with big asses.
Unfortunately present day Mike has lost most of his enthusiasm, energy and drive for this. The only good Adriano scenes any more are ones where the girl compensates for his lack of energy, and even then, it's a two-way street and the girl's bound to lose some of her own enthusiasm when fucking a guy who just seems out of it.
The best thing Mike can do for his legacy now is hire a Logan Long replacement, and let him do pretty much all the scenes, while Mike focuses on keeping the overall aesthetic intact.
