Revenge is sweet.
This one is pretty simple. A man who has not been very good to his wife is forced to watch her with another man. The reason for the revenge could be any number of things. All depends on your imagination!
The party is going rather well and the idea is presented to some of the girls that they couldn't tell the difference between one their boyfriend and the rest of the men if they were blindfolded. She puts the theory to the test and ends up pleasing the wrong guy.
A couple gets into an argument over who is the more outgoing. Neither really has done anything that outlandish so a bet is made and they decide to play a game of exhibition. Each going back and forth with "dares" till someone chickens out. Neither of them have really tried anything like this before. How far will they be able to push each other??
Two world war two fighter pilots have been competing for top dog position. Each trying to best the others records. I would play one of the fighter pilots and you would play his rivals wife. This could be either consensual or non-con. Either way he'll get a new record one way or another.
A young snoody girl takes a vacation to New Orleans. After she finds herself in a Hoodoo shop she mocks the owner belittling the idea of Hoodoo/Voodoo. This is were he teaches her a lesson by putting a spell on her and turning her into a more "open minded" individual.
Let me know if any of them sound fun!
