Interested in inter-racial swinging?
Want to watch your girlfriend get nailed to the wall by a big, black man?

Of course there's a little more to it than that.
It explores that most basic of human desires and why people seek this sort of lifestyle. What struck me was that by having an entire 'scene' devoted to black guys and hearing how they view it, there does seem to be some sort of underlying racism to it, but maybe that's just my white guilt.
For me, it's not quite obvious who is being exploited the most.
You make up your own minds about it.
