Chubby Sister Fucked By Brother After Prom

It's time for prom! I was supposed to go with my boyfriend, Tom but he decided to BREAK UP WITH ME only a few hours before the big date! I am so upset! I don't want to be some 18 year old chubby loser. I start crying on search for my brother. I know this is a last resort but I am really hoping that he will be able to come to my rescue. I CAN'T go alone...
