This might be one of the coolest “unsimulated sex” objects ever. Both actress and actor were already known persons with careers in movies and stage as well. In particular on German speaking regions. Both at ~40y, I assume also that both have stablished relationships and families (she is an incredible woman and specially a mother, already when the filming took action, this is a major point here in my view). Both decided to take the challenge on performing such erotic-thriller roles with, I would say, no constraints at all. The scenes are raw, beautiful and authentic. They are tremendously professional delivering everything on this project! The level of intimacy achieved is tremendous for two human beings. They are delivering the story about an affair between a man and a woman and that is what is actually happening there all time. I wish I could have such intimacy and complicity with all my partners, always, all time, in the way these two are having here. This makes these scenes (and behind the scenes as well) even more pleasurable. They undress, expose and touch each other, wide open legs masturbation, both perform oral sex (come on guys, his penis disappeared when she goes down on him and on the shower scene, his face is smashed against her genitalia). No graphical penetrating is actually shown at any moment but it is highly plausible that might had happened by several details such: a) raw scenes from a mid-low budget project e.g. no CGI neither prosthetic were obviously used, these two are bare naked all the time b) instinctive arm/hand movements, genitals in the “wrong alignment” become very uncomfortable. This works either you are penetrating or “only” rubbing each other. You simply cannot plan such actions. More importantly, c) some angles on Petra’s face suggest she is blushing e.g. red face, I have this impression also from the behind the scenes video. You agree on what this usually means on a girl, right? Assuming she is really blushing, there is a great chance she’s having a great moment. And specially, d) the actor is not circumcised, this is visible multiple times. After the first sex performance they have (quite nervous btw…) you have a glimpse on his dick “popping out” of the hidden angle of his leg. However - now - having no visible skin on the tip of his penis. For a non-circumcised man, this happens while penetrating (or rubbing for while…) without a condom unless you decide yourself, at some point just by chance, to expose your dick glans. Only my two cents. The movie and the scenes are really cool.
