If the sex lived up to the setups here, this might have been a must-have volume. As it is, SLS6 is merely quite good, and testament to the notion that you don't need leather, cuffs and paddles to explore the erotic sub-currents of power disparity.
In the opener, and as is true of most of the scenarios essayed here, the buildup is far hotter than the payoff as analyst Sean Michaels and patient April tussle after yet another pointless therapy session. April is a splendid subbie, and seems genuinely vulnerable and desirous only of that which will please an effectively aloof Michaels. Similarly impressive is the attention that goes into setting the mood for Alec Metro and "wife" Barrett Moore's encounter with dominant call girl Heather Lyn, but here the sex actually lives up to the stage set for it. Lyn lays into Moore's ass with a strap-on, trading off with Metro, who does much the same using only what nature gave him. An effective outing for all involved, and especially director Pachard.
