A beautiful woman, and the mesh on her body perfectly emphasizes all the attractive curves of her body. But why treat her like a backstreet whore is beyond comprehension. I've never understood people who get off on it! And if you really think your partner is a complete whore, you'd better put on a condom or something! In any case, I don't think you fuck a woman at home that rough.
Staging is super, but the script could have been finished in a more interesting way, for example, either the awakened girlfriend would have thrown the friends out into the street, or even joined them and looking at her friend obliquely would have screwed her boyfriend much cooler than a mulatto!
