Adult drama is probably the best way to describe this. And that's that, because while it would have been nice if this had some depth to it (no pun intended), this is pretty simple in its nature and in its "story". Now I reckon you can read certain things into certain characters or their behaviour. Especially the female host of the "party". But while it is not spoken out, I do not think she is subtle about her true intentions.
Having said all that, the adult part of the drama is not because of heavy thinking or understanding, but rather the fact that you have explicit intercourse shown here. And while some would consider it overall normal (if you are not getting upset about "cheating", though the characters here would beg to differ or lesbian tendencies that is). Now there might be a softer version of this, if you are interested in the character downfalls and what this is telling, but that will be up to you. This does what it says - or rather its characters are doing it - quite a lot
