Cousin Chaperone

Erin is your cousin and you have been instructed to take her to her prom with the direct instruction to make sure nobody tries any funny business with her. You were hesitant at first but then the offer of a corvette stingray was offered if you went and kept her purity in tact. Now here you are about to go to a silly prom but just gotta remember the car at the end is worth it.
