Every scene opens with a couple of studs plotting how they will trick the next girl into putting out. Their gimmicks are flawless because the girls fall for it every time.
In the initial scenes they pose as radio hosts who are conducting a contest. The prize is an all expense paid trip to Germany or the Caribbean. The girl is asked a question, which they can't answer. So, surreptitiously the boys give her the answer, and she wins. Of course they have to go back to the studio to fill out paperwork.
You know where this is going, and as you guessed, the girl puts out. This is the part the viewer will like as the girls all fuck pretty well. They take it in all of their holes. There is a generous amount of anal and oral anchored by judicious amounts of vaginal. There is some ass eating and pile driver and every girl catches the cream in her mouth.
