Synopsis:
A trio of roommates who find an alien transformation device which allows you to change into anything you want and play with it. A ruthless criminal who wants to use the device for his own shady goals. Two government agents on a desperate race to stop the device's hapless users from making a mistake they'll regret for the rest of their lives. All of them want to gain control of the device, and all of them will be in for a night they'll never forget - they'll be in for Monster's Night.

Thanks @ ElrodW for checking the story beforehand and confirming that it's not violating any of the MAU universe's rules! :)

Takes place in dkfenger's Trust Machines universe (universe can be found on deviantart). All over the globes, so called 'Venn Machines' are popping up. Those machines allow two people to enter two opposite booths and then transform each other into whatever they want for a predetermined timespan ranging from eight hours to three years. Every change is possible, including changes into the opposite gender, animals or even objects such as clothing.

Many of my Trust Machines stories are animal, creature or object tf, but this one is mainly TG, therefore I decided to post it here as well.

Sean picks up a beautiful girl in a bar. He doesn't suspect that he's bound to fall victim to one of his buddy Josh's over the top jokes...
