Tash and Suzie are both musicians and awaiting the start of rehearsals at their local concert hall. They don't like boredom...

They meet one another - by accident - in one restroom and discover they, each, have a boyfriend waiting upstairs for them.

Boyfriends with very similar kinks, in fact, so they swap places and see if they can convince them, with persuasive acting ability that, in fact, they're fucking their own girlfriends.

And that's just the beginning of a delightfully entertaining day for the girls...
