Looking for more stories

There are two stories I am looking for. I don't recall much about hte first one, other than it is a boy whose sister makes him put on girls stuff (I think) and then locks him in it, takes his picture and sends it around the school. He gets out but she acts like she did no wrong

the other is a boy living like a girl, not sure if the whole family remembers at first, but at one point, they are in a car, he/she gets out and runs, the sister runs after and tackles him/her and drags him/her back to the car. I want to say there was blackmail in this as well. And I swear the sister and friend of hers assaulted the boy/girl

any ideas?
