Teens and cheerleaders.
In this country of ours there has to be more than just a handful of male high school cheerleading coaches out there who like putting their girls through the drills - especially during tryout season. And they're not counting sheep when they can't sleep. They're counting high school cheerleader girls without panties doing high jumping open-air splits and cartwheels. They're also renting this.
The auditions in Cheerleader Auditions 2 are where this title gets it right. And the girls do a good job playing along, oblivious to the perverted coach, who gets off making them do things to flash him. Unfortunately, only three of the six girls do auditions.
The hardcore is pretty average stuff, with the only scene of note being the final one with Becky, a petite brunette who showed up to fuck first, get paid second.
