Adding quiet background music to an already overdriven soundtrack isn't a good idea by itself; doing so with an untranslated import is a killer. Every little sound reverberates like it's being blown directly into a microphone on a windy day. The girls are average. The sex is average, too.
The last scene says it all: after two guys finish doing a d.p. on one of the women, they simply clean her off by tossing a few buckets of water on her reclining form... and then they leave.
