RCT-554 - H-cup fitness instructor whispering dirty talk during private PT

With Yumi Nagasaku appearing and this concept, I was super hyped the moment I saw the cover. But I was disappointed after watching it. The two actresses aren't to blame at all. In fact, they fit the concept perfectly and worked hard! The problem is that the content is just them wearing instructor outfits and having sex in a gym (angry). They use a microphone to say dirty things, but it’s not exciting at all. It completely betrayed my expectations that they would be doing all sorts of lewd things in a fitness setting. Soft On Demand usually features 'log' actors, POV shots, and actresses playing nymphos (with lots of dirty talk). Is that style (aimed at herbivore men) popular these days? This work just followed that trend. Sigh, what a shame.
