The girls want to have a friendly competition, and you get to be judge, assistant, and prize all in one! The girls naturally will need a little help getting properly hard for measuring, so you will suck each one of them before they get the tape out and measure themselves. The winner gets to fuck you silly while you jack off the other two, and they all finish by jerking off into your face at the same time.

The actresses don't have to be anyone specific, but they need to be well-hung in order for the contest to work.
