I want to take hidden pictures of the girls standing together.
Wow, that is quite different. Are you serious about taking those pictures?
To answer your question, yes I have been thinking about it for a while now.
I am not sure where this is going but I think you could get in trouble for this, is this really worth it to you? I value your friendship too much to see you head down the wrong path. Why not just ask for the pictures?
Haha I can't ask them for a picture, that'd be dumb. They would just say no.
It is better to ask in my opinion even if they say no. The cops could find out what you did and then you could be arrested. I am worrying about you. Please try to think of your future.
