The mistake Anna and Alex are making is the same mistake a ton of other couples on these sites are making. They act as if all these different kinds of sex acts and props will make them more interesting to watch and that simply is not the case. Case in point with Lex and Iris, they are always trying new things, new costumes, new props, but there is absolutely no chemistry between them whatsoever. Same with Anna and Alex. There's no passion between these two. There's no inherent desire to see the other person pleasured. And that in turn makes any sex they have boring to watch.
Alex almost always acts as if fucking Anna is like a 9-to-5 job that he hates. And I've seen people here criticizing Alex for looking at his phone while Anna sucks his dick, but it's not as if she's sucking him off with any passion either. She's about as lifeless as a zombie while she's doing it. If I were in his shoes I'd probably be watching TV or looking at my phone too. The chemistry and passion between the two people involved are just as important as the actual sex itself. Probably even more so. The whole reason why professional porn is garbage because in most cases you can clearly see the lack of passion between the performers and they're just there to pick up a paycheck. Lex and Iris used to have that in spades but they've been sucked dry. Same can be said about Anna and Alex. but same can also be said for a ton of other couples. They're fucking each other for views and money rather than doing it because they actually like each other.
